Description

Field of invention

The present invention relates to a test device for various types of devices, devices or components, i.e. a device which is used to measure useful parameters of a device, device or component and then to analyze the parameters derived from the test. In particular, this invention relates to a test device for devices, devices or components with distributed functions, wherein a simplified test device measures basic parameters of a device, a device or a component and uses this raw data to analyze, manipulate and evaluate the test results to determine the state of the device, the Device or the component and optionally for forwarding the raw data or the status data to a further destination, for example from the smart device of a technician of a car dealership to the computer of the customer service manager, to a separate intelligent device (smart device) such as a smartphone or a tablet computer that can be used elsewhere.

In a further embodiment, the smart device can acquire the fundamental parameters from the simplified test device and transmit the fundamental parameters and optionally other information for analysis, manipulation and evaluation of the test results to determine the state of the device to a web server.

The tester of the invention is described in detail herein with respect to a battery tester, but as mentioned above is not limited thereto. In this embodiment, a simplified battery tester is connected to the terminals of a battery in order to carry out certain tests and then gives the resulting raw data for an analysis, for example a comparison of measured parameters of the battery with values that are expected from a battery in good condition and one more appropriate action to a smart device.

Background of the invention

Batteries have been widely used in many applications for years to provide electrical power needed for a wide range of applications. For example, batteries are widely used in the automotive industry to provide power for a starter to start an internal combustion engine, to power additional loads in a vehicle, and to provide electricity to electric motors that provide propulsion for the vehicle. Batteries are also used in many commercial applications for powering indoor vehicles or for providing backup or standby power for a device such as a computer or telecommunications device in the event of a power failure.

With the ubiquitous use of batteries in so many applications, it is important to know the battery condition so that the reliability of the primary application is ensured. Over the past 50 years, a number of battery testing and monitoring procedures have been developed to provide important information relating to battery condition. The simplest methods involve measuring the specific gravity of the electrolyte or measuring a voltage as well as a voltage under a given load. Measurements of a voltage under a load are evaluated by the device or by the user of the device in order to determine the maintenance status of the battery.

In the past 30 years, these methods have largely been replaced by electrical test methods, commonly referred to as "ohmic" test methods, in which the internal resistance of the battery is measured and compared with a reference value. Exemplary battery ohmic test procedures are set forth in the US publications US 6,704,629 B2 , US 7 212 006 B2 , U.S. 5,744,962 A , U.S. 3,873,911 A and many others.

In general, it is believed that these ohmic test methods are more efficient and reliable in indicating a battery condition than conventional load test methods or test methods based on relative density. However, ohmic test devices are generally relatively expensive compared to the equipment required for conventional test methods.

Furthermore, commercial ohmic test devices are "integrated", i.e. they have both the measuring and the analysis function. Such integrated battery testers are provided, for example, with test connections that are to be connected to the battery so that raw data parameters can be measured, and are also provided with a keypad or the like by means of which the user can enter several data entries relating to the specifications of a battery to be tested can, as well as with a microprocessor, memory, stored program and the like so that the parameters can be properly analyzed and a useful result is provided to the user.

The data inputs during a battery test are referred to herein as “context parameters”. An input of these context parameters into the test device is necessary so that the measured parameters of a specific battery to be tested can be meaningfully compared with the nominal specifications of a similar battery in good condition. The context parameters are used to select a suitable algorithm for calculating a battery condition and a battery condition with sufficient accuracy. Without such context parameters, the measured values derived from a battery are not sufficient to determine a battery condition or a battery condition.

For example, ohmic test devices typically measure the “open-circuit voltage” (OCV), that is, the voltage across the battery when no external loads are connected. Assume an OCV of 6.4V is measured. If the nominal operating voltage of the battery is not known, it is impossible to determine whether an OCV of 6.4V indicates a good or bad battery, or a charged or discharged battery. If the device (or the user) knows that the battery should have a voltage of 12.6V when fully charged, an OCV of 6.4V will indicate that the battery is essentially discharged and possibly defective. However, if the battery context parameters indicate that the battery is nominally a 6V battery, an OCV of 6.4V indicates that it can be considered fully charged. (It will be apparent to those skilled in the art that this is not enough to ensure that the battery is in good condition, merely that it is fully charged. Additional measurements and contextual information are needed to determine the condition of the battery.)

In an ohmic test to determine the state of a battery, certain context parameters must be used to determine a qualitative test result based on the raw data measured by the test device. Such battery context parameters can, for example, be a nominal battery voltage or an expected battery voltage, a nominal battery capacity or a nominal battery power, a battery power system, a battery type, a nominal battery size, a battery manufacturer, a battery chemistry, a battery switch, a battery temperature, a battery pack configuration, a battery location, a test point location, a connection type, a connection material, a battery model, etc. In existing commercial battery testers, such context parameters are typically determined by the user and appropriate values are sequentially entered into the tester.

More precisely, depending on the test application, more or less critical context parameters must be entered by the user before a test can be carried out and qualitative results can be determined. This requires that the tester have a user interface for entering these values. The user interface of the typical integrated battery tester is any display screen associated with a keyboard, keypad, or a number of buttons that the user presses in turn to enter or select values, typically in response to prompts displayed on the screen. Through this interface, the user selects suitable context values for the test, initiates the test and carries out actions after the test, for example viewing test results and printing or saving the results. The user interfaces provided in currently available battery testers are typically cumbersome and require a large number of button presses so that they take a long time to operate. Furthermore, user interfaces currently in use may be difficult to operate without instructions. Both can lead to operating errors and the omission of critical context information.

In particular, the process for determining and entering context parameters in a battery tester is fraught with errors and uncertainty. When prompted to enter battery context parameters, the user must understand which parameters are needed. The user must be able to determine these parameters by viewing the battery or otherwise available information. The user must enter the parameters accurately and completely. Often enough information about the battery is not available for the user to determine the basic and critical context parameters. This problem is particularly pronounced in the case of AGM batteries (absorbed glass mat batteries). The electrical performance properties, particularly ohmic behavior, of AGM batteries can vary considerably from model to model and from manufacturer to manufacturer. Accurate ohmic testing of AGM batteries relies on an accurate and precise understanding of the determined ohmic context parameters for the battery model. However, such information is not provided on the battery label. In addition, even if the resistive properties for a particular battery model were known, the same battery model can be sold under many different names, making it virtually impossible to determine the origin and the appropriate context parameters for the battery because the battery is not sufficiently identified can be.

In practice, due to the difficulty of accurately and specifically identifying batteries, context parameters are often generalized so that broad categories of batteries are grouped together and a general context parameter setting is used for the entire category. For example, the context parameter "Battery Construction Type" has been generalized to include three basic (and visually identifiable) groups of batteries called WET, AGM FLAT, and AGM Spiral. The user will select the closest of these battery type groups based on the visual inspection of the battery. The ultimate accuracy of the analysis is severely limited, however, as each battery has certain battery type characteristics which, if correctly identified, could be used to determine a much more accurate battery test result. Ideally, each battery model would have a unique design parameter that reflects the very specific properties of the battery.

However, the identification of specific battery type properties is very difficult. It is impractical or problematic for battery manufacturers to include specific battery type details on the battery label. Instead, only general specifications of interest to the buyer are given on the label. In addition, the same battery is often sold under different brand names unrelated to the original manufacturer, making it virtually impossible to identify specific battery characteristics by looking at the label. Furthermore, as mentioned above, even if the precise context parameters can be identified by the user, the input of this information into the test device is critical and is often performed incorrectly. Often times, the technician using the test fixture does not enter the information properly so that one or more context parameters are overlooked or entered incorrectly. Incomplete or incorrect entry of context parameters leads to incorrect test results.

After entering the context parameters into the battery tester, the user initiates a battery test. The tester will measure certain raw data parameters of the battery. Typically only two or three raw parameters are measured, for example a voltage and a resistance value, and occasionally the temperature. However, many other parameters are measurable and potentially useful in determining the condition of the battery, including capacity, reactance, inductance, fluid level, specific gravity of the electrolyte, current, etc., and are accordingly intended to fall within the scope of the invention. These measured raw parameters are then used in complex algorithms to determine qualitative results as a function of the entered context parameters. These qualitative results indicate the condition of the battery and can include, for example, an estimated cold start performance, a state of charge, a maintenance status, a remaining battery life, a start maintenance status and other variables. The ascertained qualitative values are then compared with the context parameters entered by the user in order to come to a conclusion, typically pass or fail. These calculations are performed using a microprocessor and usually displayed on the user interface screen, and they can be printed out for future use or stored in the device's memory. In connection with vehicle batteries, it is also known to start the internal combustion engine of the vehicle and measure the minimum voltage across the battery during cranking, which indicates a battery condition, and to measure the voltage and current ripple after the internal combustion engine has started, which indicates generator power indicates.

In more complex battery test environments, such as when testing a parallel pack of batteries or when testing and comparing multiple batteries in a row of batteries, the hardware and firmware of the tester must have a long and complex test sequence, such as instructing the user to perform multiple steps, and then storing and comparing qualitative and quantitative results from multiple tests.

As testing of batteries has evolved and the results of battery tests become more important in improving quality and handling of warranty for batteries, it is desirable to be able to obtain the test reports or test records from the test apparatus so that they can be collected and further analyzed or distributed or combined with other information, for example to provide operational reports. This storage and exchange of information is often cumbersome and expensive. Typically, this capability requires a memory as part of the device so that a large number of test records can be stored, along with an interface that allows the files stored by the device to be transferred to another device, such as a computer system to the Track data for a vehicle fleet. Procedure for this transfer of stored data to another Devices involve the use of removable memory cards or on-board memory that can be read through a data port such as a serial port or a "USB" port connected to a computer. Alternative methods include a "WiFi", "Bluetooth" or other radio or infrared connection between the test device and a remote device so that test reports can be sent to a network.

It can thus be seen that, even if the function of a battery tester is comparatively simple per se, since only a few raw data parameters can be determined on the basis of the battery itself, commercially available battery testers have become complex and expensive in order to be able to provide useful qualitative results Indicate battery health and provide workable recommendations for a wide variety of battery types, and also provide the ability to save and share results and reports, print results, send results to a remote device for further analysis, and the like.

Similar problems arise with other forms of specialized integrated test equipment, such as a specialized device for reading diagnostic data from an on-board diagnostic (OBD) port of a car, a device for verifying proper performance of telecommunications equipment, and many other devices. More precisely, there are numerous examples of test devices of various types in which the actual collection of data, downloading of status codes, performing simple tests and the like compared to the analysis of the test results, the receipt of required context data, the provision of a user interface, the dissemination the results to other devices and the like is a simple task.

The US 7 209 813 B2 discloses a mobile phone that can be connected to an existing vehicle data interface. In addition, the mobile phone can be connected to a battery in order to perform the functions of a battery testing device.

Objects and Summary of the Invention

It is therefore an object of this invention to provide a simplified device for testing devices, devices or components, that is to say for measuring relevant parameters of the devices, devices or components, and for transmitting the measured values to an associated external "Smart" device, which is connected with little effort -Device "that can also be used for other purposes, for example a smartphone, a tablet computer or the like. In this way, the device-specific test device can be considerably simplified, and already existing capabilities of the smart device can be "exploited", i.e. used additionally.

The smart device can be designed with software for performing an analysis of the parameters derived from the test, or it can be designed with software for connection to a remote web server so that the web server can perform the analysis based on the parameters derived from the test derived parameters. A test device according to the invention thus has a simplified test device, a suitably programmed smart device and optionally a suitably programmed, remotely connected web server.

In connection with testing a battery, the simplified battery tester measures the basic battery parameters of interest, typically an open circuit voltage, an internal resistance of the battery and a temperature, and appropriately sends this raw data to the smart device for analysis, Evaluation, determination of results and further processing of test data. More specifically, in this way, instead of the battery test device, the external smart device is provided with a memory, a user interface for acquiring battery test context information and a circuit for displaying, storing and transmitting results and test reports.

The external smart device can also be used for other purposes so that it is not used solely for the purpose of battery testing per se. More specifically, the external smart device can be a smartphone, a tablet computer, a laptop, or the like. Thus, dividing the function of the known battery test devices to the simple, low-cost battery test device and the already existing external smart device according to the present invention has many advantages, which are discussed in more detail below.

In summary, these advantages include a substantially reduced effort for the battery test device, since the test circuit can be constructed very simply, enabling an input of the context parameters by means of the sophisticated user interface that is already provided by the external smart device, which this task for the user simplified, enabling use of the memory and the Computing power of the smart device to perform the analysis of the raw data and enabling use of the sophisticated communication capabilities of the smart device to provide convenient communication of test results to a remote device. Furthermore, according to the invention, the image sensor contained in such smart devices can also be used for several purposes, which is explained in more detail below.

As mentioned above, the test devices of the invention can be used in applications other than battery testing per se, in other words, with a distribution of the data measurement function and the analysis function to a simplified test device and an existing smart device capable of doing so, others Perform tasks that allow for a "use" of the capabilities of the smart device, which are generally much more sophisticated than known integrated testers. This enables, for example, a technician, who will typically have a smart device for personal and business use, to use that device in conjunction with one or more simplified test devices, each for easily obtaining useful raw data from a variety of different devices, devices or components are used.

For example, it is easy to imagine a car mechanic having a simplified battery tester and a different simplified device to connect to the on-board diagnostic (OBD) port that is used to download various data objects used in verifying vehicle operation and useful for tracking defects, is provided on, owns (or is fitted with) modern vehicles. Both devices would read raw data and transmit it to a smart device for analysis. With this device and a smart device, the mechanic could avoid having to buy a separate built-in battery tester and an OBD tester, which essentially saves the cost of the tools needed. Further, the smart device would be useful for all of the purposes that such devices are used, both personal and business, so that the cost of the smart device would not weigh on the mechanic's tooling budget.

• Es ist eine Aufgabe dieser Erfindung, die Benutzerschnittstelle, den Prozessor, den Speicher, den Bildsensor, die Kommunikationseinrichtung, die Fähigkeit, bequem Software herunterzuladen, die die Smart-Vorrichtung für eine Analyse von Daten, die von verschiedenen vereinfachten Prüfvorrichtungen geliefert werden, anpassen, und andere Komponenten und Fähigkeiten einer externen Smart-Vorrichtung anstelle der Batterieprüfschaltung beispielsweise zum Interagieren mit dem Benutzer, Erfassen von Batteriekontextinformation, Berechnen von qualitativen Ergebnissen und Verwalten von Ergebnissen einzusetzen, wodurch der Aufwand und die Komplexität der speziell vorgesehenen Batterieprüfvorrichtung verringert wird.

Referring again to an embodiment of the invention in which the simplified test apparatus is used for battery testing (but remembering that the invention is not so limited), the objects and advantages of the invention will be further explained, it being noted that many of these objects and benefits are not limited to testing batteries, but can be useful when testing various devices, devices and components:

• It is an object of this invention to provide the user interface, processor, memory, image sensor, communications facility, the ability to conveniently download software that customize the smart device for analysis of data provided by various simplified test devices, and to use other components and capabilities of an external smart device in place of the battery test circuit, for example to interact with the user, capture battery context information, calculate qualitative results, and manage results, thereby reducing the overhead and complexity of the dedicated battery test device.

It is a further object of this invention to provide the user interface, image sensor, communication device, and processing device of a portable device such as a smartphone or tablet computer for performing the tasks of accepting user-entered battery context information, executing algorithms for calculating qualitative battery test results, and displaying and / or transferring these results, whereby the effort and complexity of providing user interfaces, keyboards, communication systems, a memory and other elements in a specially provided battery test device, as is necessary in known integrated battery test devices, can be avoided.

It is another object of this invention to provide a simplified battery tester that measures basic battery values and communicates that information to a remote smart device. The remote smart device is provided with software that prompts the user for contextual information and guides the user through a series of actions and inputs to complete a qualitative analysis of the battery. The remote smart device is adapted to run a wide variety of software programs, each program being specifically tailored to analyze a particular battery type or application. The software of the remote device is designed such that the software can be updated at any time to improve or modify the analysis algorithm, for example by means of a conventional software download, so that the simplified battery test device does not have to be capable of being updated to give better results.

The remote smart device can also access data for improving or modifying the test algorithm by updating the locally stored list of critical algorithm parameters so that no software update is required, only an adjustment of critical logic values. Such an update can be accomplished by simply interacting with an appropriately configured web server.

According to a further aspect of the invention, a simplified battery testing device measures basic battery values (“raw data”) and forwards this information to a remote smart device as set out above. The remote smart device is reconfigured with software that prompts the user for appropriate contextual information. Such contextual information (e.g. battery model, brand, size, type, standard power, voltage, unique ID) can be entered manually from information on the battery label, or the software can be used to use the camera or other digital sensor or receiver to acquire a battery identification code ( UPC code, barcode or other proprietary code). It is also contemplated that batteries may contain a radio identification (RFID) chip that transmits battery identification data when activated by an associated RFID receiver included in the simplified battery tester.

In a further embodiment of the invention, upon receipt of the raw data and context information or a battery identification code by the smart device, the smart device communicates this accumulation of raw data and context information or battery identification code to a remote web server. If the raw data is accompanied by context information, an algorithm for determining the state of the battery based on the raw battery data and the context information is executed on the web server. Alternatively, if the raw battery data is accompanied by a battery identification code, a program configured to retrieve battery context information for the battery from a database is executed on the web server, and then the algorithm for determining the condition of the battery is executed.

According to a particular advantage of this latter aspect of the invention, the smart device does not have to be configured with a specific analysis algorithm, since this function is taken over by the software on the web server. Appropriate analysis software runs on the web server and returns the result data to the smart device for presentation to the user. In this way, the software on the smart device can be kept simple and only focused on collecting information and providing a user interface, while the web server application is responsible for executing the appropriate algorithms. In this embodiment, the simplified test device provides raw battery data, the smart device provides a user interface for the collection of contextual and other test information from the user, and the web server software performs all analysis and diagnostic tasks. In this way, the cost and complexity of maintaining and improving the diagnostic algorithm is reduced since software on the smart device does not need to be modified or updated; all updates, e.g. when new battery types appear, are carried out simply by updating the databases accessed by the web server. Furthermore, the fact that the software application program ("app") running on the smart device can be considerably simplified so that it is essentially only used to communicate data from the simplified battery tester to the web server thereby making it easier to allow different types of smart devices to be used in implementing the invention.

In another modification, the simplified battery tester measures basic battery values and passes this raw data to a smart device. The smart device is configured with software commonly known, for example, as a web browser, or other similar software that interfaces with a specific remote web server. In this embodiment, the smart device simply forwards the raw data to the server and the web server responds by presenting a "web form" to the smart device's browser. The smart device then prompts the user for contextual information that is needed for a full analysis. Thus, the remote web server is configured with software that causes the smart device to display one or more forms prompting the user to enter appropriate contextual information, and upon completion of the form or forms, the web server performs the analysis using the raw battery data and the context data provided by the user. In this embodiment of the invention, the smart device need only be configured with basic "web browser" software to provide a connection to the web server; no dedicated application ("app") need be provided on the smart device.

In another embodiment of the invention, a simplified battery tester measures basic battery values and displays those values in human readable form. The user can then simply enter the raw data into a conventional web browser (ie, on a conventional PC) that is designed to accept input of basic battery values and contextual data. The web browser then delivers this information to a remote web server. The web server software is designed to apply the appropriate algorithms to the entered data and return the test results to the browser. In this way it is possible to bypass the smart device entirely.

A particular advantage of the present invention is that the simplified test apparatus only produces raw data, so it is very unlikely that there will be a need to update its capabilities, for example when new types of batteries become available. Accordingly, the simplified test device should be able to be used for many years even as new types of batteries become available and need to be tested. When the analysis of the raw data is performed by the smart device, new methods, algorithms, battery applications and context information properties can be carried over to the smart device by a simple software download and incorporated into final qualitative results; if the analysis is performed by a web server, only the software on the web server needs to be updated, in both cases the simplified test device does not have to be modified. Such changes can be made quickly and easily to the software residing on the remote smart device or on the web server by simply updating the appropriate application software. This method greatly increases the range of battery types, battery configurations, and battery applications that can be tested using the same simplified battery tester.

According to another aspect of the invention, a battery testing device communicates raw data to a smart device, and the smart device acquires battery identification information directly from the battery that can be used to reliably identify the specific battery model without the user reading and understanding information on the battery label must and must enter this information. Using the battery identification information, specific context values which are important for an accurate battery test are accessed in a database and these are made available for the analysis and diagnosis algorithm. In this way, the battery testing device and the smart device can be used to test batteries without the user entering data. This simplifies the operation of the test device and eliminates a frequently occurring source of error.

It is another object of this invention to provide a simplified battery tester that provides raw information regarding an objective battery parameter quickly and conveniently to a remote smart device using a simple, low-cost method. This simple, low-cost communication between the simplified battery test device and the smart device can be carried out in various ways, each known from different fields.

For example, the raw battery parameter information can be transmitted quickly and conveniently from a simple test device to a remote device by a wired communication technique such as serial communication performed using the known USB communication technique. Alternatively, the raw battery parameter information can be transmitted quickly and conveniently from a simplified test device to a remote device using a wireless communication interface such as the well-known “WiFi” or “Bluetooth” radio communication technology. Such wired and radio communication techniques are supported by the smart devices used today and can be easily implemented in a simple battery tester.

Both wired and radio communication technology, however, are subject to certain potential complications; the cables required for wired communication can be lost or damaged, and the standards for WiFi or Bluetooth can change over time. If these complications could be prevented due to a simpler communication technique, it being noted in particular that there is no specific reason for communication from the smart device to the simplified battery test device, but only for communication in the opposite direction, a further advantage would be obtained become.

Therefore, it is a further object of this invention to provide a method for transmitting raw battery parameter information from a simplified battery testing device to a remote smart To provide apparatus in a quick and convenient manner, avoiding a wired data or communication bus or a radio transmission method. Such a method enables a battery testing device which is very inexpensive and has few problems.

According to this latter aspect of the invention, raw battery parameter information is transmitted from a simplified battery tester to a smart device by allowing the simplified test device to display a graphic image such as a bitmap image that is visually recognized by a smart device. Since the conventional smart devices nowadays all contain an image sensor and are able to employ sophisticated software to recognize such bitmaps and to read data therefrom, provision of communication from the simplified battery tester to the smart device is thereon Do not complicate the functions already provided by the smart device; the battery tester need only be able to display a bitmap containing the raw data in a form that can be recognized by the smart device, which is easily possible.

One known form of such bitmaps is known in the industry as the "QR" code, which is traditionally used to convey characters from, for example, a magazine to a smart device. For example, a user can cause the camera of his or her smartphone to scan a QR code in an advertisement in a magazine. The QR code usually stores an Internet address that can then be used immediately by the smartphone to access the website of the person who placed the ad. Such QR codes can easily be generated for coding raw data, for example measurements that are carried out with regard to a battery to be tested, and displayed on a screen of a simplified battery test device and read from there by the smart device. Therefore, it is an object of this invention to provide a means and method for quickly and conveniently transmitting raw battery parameter information from a simplified battery tester by enabling the simplified tester to display a QR code containing the battery parameter information. The QR code is visually captured by an image sensor or camera of the remote smart device. The smart device then uses the raw data transmitted via the QR code and the battery context information entered by the operator to evaluate the battery in the manner previously described.

It is also within the scope of the invention that multiple sets of raw data are collected and these are transmitted in separate operations from the simplified battery tester to the smart device. For example, the simplified battery tester can measure a voltage, a temperature and a resistance and display a QR code with these three values and then wait for a starting sequence of an internal combustion engine. When a starting sequence of an internal combustion engine is detected, it will detect the starting voltage (i.e. the minimum voltage reached by the battery during starting of the internal combustion engine), a generator voltage and a generator ripple. After collecting these values, it will generate and display a new QR code that contains these additional values. The smart device will receive the QR codes in turn, analyze the data and display the qualitative result.

It is also within the scope of this invention for the simplified battery tester to display a QR code with the battery parameter data information associated with address information such as an Internet address or a specific Internet Protocol (IP) address so that a smart device or other application that receives this code can pass all the information directly to a specific web server that is designed to analyze the associated battery parameter data. An exemplary string could be
"Http://www.testdata.com/?/Xb342C12a5d2h331x4f". In this example, www.testdata.com is the address for the web server on which the diagnostic software is located and the following string contains part or the The entirety of the data necessary to determine a diagnostic result. Using this method avoids the need for the smart device to contain the diagnostic software. Instead, the smart device only needs to be able to transfer the test data string to the web Server and display results returned by the web server.

It is desirable to prevent unauthorized software applications from using the readings produced by the simplified battery tester - that is, it is desirable to prevent unauthorized vendors from selling software for smart devices that functionally interact with the simplified battery tester of this invention. Accordingly, it is a further object of this invention to provide the raw battery parameter information after encoding the raw battery parameter information into a series of values which Do not directly display battery measurements, and then convert these encrypted values into a graphical image that can be scanned by a remote device for transmission from a simplified battery tester to a remote smart device. In this embodiment of the invention, the remote smart device contains software that is capable of deciphering the data so that the values can be analyzed as a function of battery context information and used to determine qualitative battery performance information.

In another embodiment of the invention, pre-existing wiring interfaces in a vehicle can be used to minimize the number of connections that must be made between the battery under test and the smart device. One such method is to use the existing DC power wiring in the vehicle to relay the raw battery parameter information. By using the existing power wiring in the vehicle, the battery tester connected to the battery, which is also connected to the wiring of the vehicle, can transmit the raw battery parameter information over the vehicle's DC wiring using one of many possible protocols. A receiving device remotely connected to the DC power wiring from the battery tester can then receive the battery parameter information communicated over the DC wiring.

More precisely, modern vehicles all have an on-board diagnostic port (OBD port). An “OBD scan tool” is connected to the OBD port by a technician in order to detect vehicle operating data, fault codes and the like. The OBD port connections contain the DC power wires (B + and ground) and are thus connected directly to the battery. The simplified battery test device can be connected to the battery, carry out the desired test and then transfer the raw data to the OBD port via the power wiring. A typical OBD scan tool can be configured to receive the raw data. In this manner, the raw battery parameters can be transmitted to a remote device by the appropriately configured OBD scan tool using any of many communication methods already in use by OBD readers. Such methods include Bluetooth, WiFi, and direct wired communication, but could also include displaying an optical code described above.

It is an object of this invention to improve the accuracy and reliability of battery measurements by automatically measuring one or more battery characteristics multiple times and automatically comparing results to ensure that the measurements are consistent within an acceptable range. If the results are consistent within an acceptable range, the values of the sequentially measured results can be automatically averaged to produce an average or otherwise statistically modified to produce a result that best reflects the true measurement. If the results obtained in sequence are not sufficiently consistent, then the simplified battery tester will automatically measure the property n more times, where n could be any value greater than or equal to one, and the results are further analyzed for consistency. If the results are not sufficiently consistent, the test device can clearly indicate a failed test on the display or generate graphical code which, when scanned from a remote device, indicates a failed test so that the user can initiate a new test .

It is an object of this invention to quickly, conveniently, and accurately capture battery context information on the smart device so that the smart device software can accurately process the raw data from the simplified battery tester without the user of the tester or smart device evaluate or enter certain context information. This will allow automatic digital input of battery properties and context information, so that operator errors as well as input of battery test data are eliminated. This data is captured digitally using RFID, optical scanning or other digital techniques to eliminate the potential operator errors and reduce the overall inspection time.

In one embodiment, a software application is running on the smart device that prompts the operator to point the image sensor at a bar code on the battery label. The image sensor captures the bar code image and the software determines the battery identification information based on the code number. Once the battery identification information is known, generic or specific battery context parameters can be retrieved from a local database stored on the smart device containing a long list of battery identities and their associated context parameters, or from a remote server maintaining such a database, can be downloaded and used in the analysis of the tested battery.

The battery identification information can simply be the well known Universal Product Code (UPC) or some other specially designed code that can be optically read by the smart device. Alternatively, the battery identification information can be stored digitally and transmitted as a radio code and detected, for example using known radio frequency identification (RFID) techniques. For example, the battery manufacturer can insert an “RFID chip” into the battery during manufacture, and the battery ID can be received by an RFID receiver in the simplified battery tester and transmitted to the smart device using one of the methods described above.

The battery identification information enables the battery to be identified as a specific battery model. As previously mentioned, in known battery testing methods, the battery model information is generally assigned to one of a few battery types referred to as battery construction or design, e.g. wet, maintenance free, absorbed glass mat (AGM), gel cell, etc. Each battery type is one or more generic Assigned conversion characteristics that are used by the analysis algorithm to convert raw battery information into generally understandable battery performance measurements such as cold start current (CCA), start current (CA) or ampere hours (Ah).

For all battery types, especially for AGM batteries, however, the generic conversion characteristics are only approximations and are inherently inaccurate compared to a specific conversion characteristic for a particular battery model.

In one embodiment, the smart device is configured to contain specific contextual details, including diagnostic algorithm details, and specific conversion characteristics or battery type factors for specific battery models. Once the specific battery model is known, the specific battery context details can be used to determine the test results. In this way, the algorithm for testing a specific battery can be tailored very precisely to the specific battery model being tested, which improves the accuracy of the diagnosis.

Specific battery context details for a battery model can include objects such as specially tailored battery type factors, reference performance values based on one or more test standards, a battery brand, a battery model name and number, a battery design, a warranty period, parameters relating to an expected end of life, and any other information about a Battery model that could be useful in evaluating the performance and health of a battery.

If the battery is configured with a code that is uniquely assigned to a specific battery, for example a serial number, additional identification information can be determined from the serial number. For example, the serial number can be optically scanned and broken down into components, which can include a battery brand, a battery model, a unique battery ID, a date of manufacture, a date of origin, a factory of origin, or any other data encoded in the code by the battery manufacturer are. The smart device software can determine the specific information contained in the code, or the smart device software can be configured to transmit the code to a web server that is used to identify and determine the type of code specific information components and values in the code based on the code type. The web server would then return the information to the smart device along with relevant specific battery test parameters to be used to analyze the battery.

In this way, battery manufacturers can maintain, modify and update the critical parameters and test thresholds against which their batteries are assessed. By modifying the parameters in a database maintained on a web server, a subsequent check is carried out according to the updated parameters. This allows settings and enhancements to be disseminated very efficiently and quickly without having to update the firmware encoded in most battery testers, and it even avoids the relatively hassle-free process of updating the software on the smart device as the updated parameters are used by the software of the smart device as soon as the master parameter database, which is stored on the web server, is updated.

It is a further object of this invention to quickly and conveniently add useful identification information to an inspection record so that the inspection report can be readily associated with a particular battery, vehicle, facility, location, building, or other useful identifying attribute can. This can be done easily by adding such identification information using hardware and software already on a remote smart device are present.

For example, in connection with a vehicle, the software on the remote smart device may prompt the user either before or after the remote smart device scans the display of the simplified battery tester to capture the graphic code containing the simplified battery measurements for identification details of the Battery or the vehicle. The details could include the vehicle identification number (VIN), which can be optically scanned or photographed by the remote smart device's image sensor and then stored in conjunction with the battery status information for later use. In this context, the scanned image of a human-readable version of the VIN can be converted by the software using optical character recognition into an alphanumeric character string representing the vehicle identification number and stored as a field along with the other data relating to the battery becomes. Alternatively, the VIN can be present on the vehicle in the form of a bar code that can be scanned by the image sensor of a remote device and converted to an alphanumeric code.

The VIN can be correlated to a specific vehicle manufacturer and model using a database residing in the smart device or accessed on a web server over the Internet. The make and model of a vehicle can be correlated with specific contextual details that can be used to improve the accuracy of the diagnosis. For example, the VIN can be used to determine the manufacturer-specified battery for a vehicle, and the reference values for that battery can be used as context information for the vehicle.

Such information related to the characteristics of a specific vehicle can also be used to address another common problem. It is particularly difficult to test batteries that are located in remote areas in the vehicle. Often times, batteries are located under a seat or in a secluded room that is not easily accessible. In this case, remote battery connections are provided for jump starting or for enabling basic battery diagnostic procedures in a conveniently accessible location. However, ohmic tests of a battery performed on the remote terminals are corrupted by the resistance created by the connections between the battery and the remote terminals used for testing. Once the resistance of the particular configuration is known, the test results can be adjusted to obtain an accurate diagnosis. A database of such adjustment factors for each vehicle can be created, and when the VIN is scanned, the smart device or web server can look up and apply the appropriate adjustment factor so that an extremely accurate test result is obtained.

Other useful identifying information that can be similarly captured and stored with the inspection report includes a battery bar code, serial number or part number, a photo of the battery, the vehicle's license plate number, the number of a vehicle in a vehicle fleet, the location of the test, as determined by a GPS provided on the remote smart device, a photo of the battery installation, or any other information that can be used to identify the battery being tested.

It is a further object of the present invention to automatically integrate battery test report information with other maintenance information related to a particular vehicle in maintenance. After simplified battery measurement information has been obtained by the remote smart device and converted into battery status information as a function of the context information, a battery test report is generated. This battery test report contains battery identification information that can be correlated to a particular vehicle or owner. By using one or more related identification values, the battery test report can be automatically combined with other records relating to the same vehicle, vehicle type, or owner.

As previously mentioned, while the invention is described herein in connection with testing a battery, the invention can be applied to testing numerous forms of devices, devices, and components. In any event, a simplified test fixture will be connected to the device, device or component to be tested, measure raw data, collect stored data, and similar operations to obtain raw data useful for determining the condition of the device being tested Device or component can be analyzed, perform and transfer the raw data to an associated smart device. The smart device will then perform the analysis, typically upon input of context parameters indicative of normal operation of the device, device, or component and providing useful output. In this way, the effort for the test device can be minimized, and the very sophisticated analysis, display, user interface, image acquisition, data storage, software update and communication capabilities of the smart device can be used in numerous uses.

Other aspects and features of the invention will become apparent to those skilled in the art from the following description.

Detailed description of the preferred embodiments

As mentioned earlier, shows 1 an overall structure of a test device with a distributed measurement and analysis function according to the invention. The test device is shown in connection with testing a vehicle battery, but the invention is not limited to what is explained in more detail below.

As previously mentioned, the basic function is a measurement of battery parameters, typically the open circuit voltage (OCV), resistance and temperature of a battery 10 , through a simplified battery tester 12 when this is done by connecting to the battery 10 Is "booted up". The technique used to measure resistance may generally be that described in the aforementioned Huang patents and summarized below, but it may be any other technique. Values other than those mentioned can also be measured, as noted earlier.

In a more complex test, after measuring the aforementioned basic parameters, the user can be prompted to start the vehicle's internal combustion engine. This will result in additional measurements, typically the minimum voltage measured across the battery during engine start-up, which is useful in evaluating the battery, and the voltage and frequency of a ripple detected after the engine is started which is useful when evaluating the alternator or alternator. The steps necessary to perform these tests are described below with reference to FIG 4th described.

After performing the simplified battery testing device 12 supported tests in the manner described above then transmits the simplified battery tester 12 this raw battery parameter data to a smart device 14th what by the reference number 16 is specified.

Such intelligent devices 14th , which typically include devices commonly known as smartphones or tablet computers, as well as other devices with the The capabilities required have several features that are used in implementing the invention. For example, such smart devices include image sensors that are connected to image processing circuitry and software so that they can decode symbols such as a so-called QR code, which provides an alphanumeric string consisting of letters and numbers. These smart devices are also equipped with memory and considerable processing power, with the ability to download software (commonly referred to as an “app” for the English word “application”) that adapts the device to a new use, and have the ability to communicate in several ways. Thus, to adapt an already existing smart device for use in connection with the present invention, one need only download appropriate software, for example software that implements the steps discussed below.

As previously mentioned, the raw data can be retrieved from the simplified battery tester in several ways 12 to the smart device 14th including a wired connection or a wireless connection. Currently the preferred method is to display an encoded version of the raw data on a screen 13 the battery tester 12 , e.g. in the form of a QR code (see 2 ), and reading it by an image sensor or camera included in the smart device 14th is included. The smart device 14th , the battery context information such as the battery power has been made available (for example, through user input via a touchscreen 18th ), then analyzes the raw data according to a stored algorithm and determines the battery status.

The smart device 14th can be used for optical reading of a barcode 27 or another code on the battery 10 containing battery identification information. Alternatively, the smart device 14th use other methods of acquiring battery identification information from the battery. For example (as below in connection with 6th is discussed) the simplified test device 12 an RFID receiver capable of receiving information from an RFID chip supplied by the manufacturer as part of the battery 10 is provided. The one from the RFID receiver in the simplified test fixture 12 received information may be transmitted to the smart device along with the battery check information in any of the ways described herein. Upon receipt of the battery identification information, the smart device is 14th able to select specific battery context information for the particular battery being tested. The smart device 14th may be provided with a database of specific batteries and the corresponding context information for each of them, or the smart device 14th can pass the battery identification information to a remote web server, what with 30th indicates where context information is available for that specific battery; the web server then provides the appropriate battery context information for a calculation of battery condition results to the smart device 14th continue.

Optionally, the smart device 14th the battery status data to a remote computer 20th transferred, for example to the maintenance system of a dealer or a workshop. In that case the smart device will 14th also prefers vehicle identification data such as the VIN obtained by the smart device from the tag 22nd , which is provided on all vehicles, can be read what by the reference number 24 or the number of the license plate 26th of the vehicle, also through the smart device 14th what can be read by the reference number 28 is specified, transferred. The battery status data and other identifications can alternatively or additionally via a printer 25th can be printed out.

As noted earlier, the smart device 14th typically need battery context information, typically including the battery type and nominal specifications of the battery, and the battery power type to which the specifications refer, in order to perform the analysis. This information is usually printed on the label or sticker on the battery. The user can enter this information directly in response to prompts displayed on the smart device screen. Alternatively, the smart device can obtain this data by user input of a battery identification such as the part number, whereupon the specification of the battery is downloaded from the Internet, for example from the website of the battery manufacturer, indicated by the reference number 30th is specified. The smart device 14th may also be able to identify the battery from a barcode, RFID storage device, or similar identification 27 on the battery 10 to read, if available, and also receives the nominal specification and other context information from a database that is available on the web server, provided the relevant specifications are not already contained in the RFID info or the barcode.

As mentioned before, in most cases batteries are grouped into main type categories, for example “wet”, “VRLA” or maintenance free and AGMs that have a common resistance behavior. This was advantageous as the user can expect to determine the general type of a particular battery by inspecting it. The battery tester or, in the case of this invention, the smart device 14th is typically provided with specific algorithms that are generally accurate enough to test any type of battery. However, it was found that within one type category, in particular the AGM type, there are differences with regard to the ohmic behavior of batteries. If a specific battery can be tested using specific algorithms appropriate for the model, the test accuracy is improved. By allowing the smart device to identify a specific battery as previously described, the smart device can download not only battery specifications, but also certain algorithm parameters for that specific battery model. Downloadable information could also include a specific battery type factor, battery warranty period, and other useful properties that cannot be readily ascertained.

2 Figure 12 shows a schematic view of the simplified battery testing device 12 according to the invention. As shown, the device 12 a central unit 32 which contains the circuitry necessary to carry out the functions described, which is explained below with reference to FIG 3 discussed in more detail, an advertisement 13 and a positive and a negative spring clamp 34 and 36 for convenient attachment to the poles of a battery 10 , as in 1 is shown on. The clamps 34 and 36 are via cable 38 and 40 in a conventional manner with the internal circuitry of the device 12 connected. The clamps 34 and 36 and their associated cables 38 and 40 can be designed as so-called Kelvin clamps, which are conventionally used, with separate conductors for signal level currents such as the voltage across the battery 10 and higher currents such as the current when a load resistor for measuring the internal resistance of the same is connected across the battery. See also the Huang patents mentioned above. One of the clamps 34 and 36 can have a temperature sensor 42 to measure the temperature of the battery 10 contain.

3 Figure 3 shows a block diagram of the components of the simplified battery tester 12 the invention. These include a microprocessor control unit (MCU) 44 , an ad 13 , Electric wire 38 and 40 who have favourited the MCU 44 with the battery 10 that is to be checked, connect, and a transistor switch 46 . As mentioned earlier, the cables can 38 and 40 each in Kelvin clamps 34 and 36 end up. When used for other types of tests, the MCU software that runs the test equipment 12 optimized, stored and executed with regard to testing a particular type of device, device or component, and the testing device will be provided with suitable connection components.

4th As previously mentioned, shows the basic steps in the process performed by the simplified battery tester 12 when connected to a battery. In step 50 becomes the device 12 connected; the process begins immediately with such a "start-up" of the test device 12 . As indicated at 52, there is an initial delay for a duration of N (e.g. five) seconds to allow transient behavior to subside, for example to ensure that the clamps 34 and 36 good contact with the battery terminals 10 produce.

In step 54 guides the device 12 a number X identical measurements of basic parameters of the battery 10 out. As previously explained, these measurements will typically include an initial measurement of the open circuit voltage (OCV) across the battery. An "ohm value" (resistance value) for the internal resistance r of a battery 10 can then be done by measuring the voltage V _B (equivalent to OCV) across the battery using contacts 47 and 47 ' Connect a load to a known resistor R across the battery for a short period of time by closing the switch 46 so that about contacts 43 and 43 ' taking a single short pulse of large current I from the battery and measuring the voltage V _R across the load R using contacts 45 and 45 ' while again measuring the voltage V _B 'across the battery. The current I drawn from the battery is then _{calculated by I = V R} / R and the internal resistance r of the battery is calculated by r = V _B - V _B '/ I. See also the Huang patents noted above, it being understood that the invention is not so limited. The result gives values for the OCV and the internal resistance; the temperature of the battery 10 can also be measured using a contact 42 , like already mentioned before.

How through the steps 56 , 58 and 60 specified, the measuring step 54 Repeated X times to ensure accuracy.

If the measured battery parameter data determined in this way are considered reliable, they can be used as in step 62 specified and compressed as in step 64 specified before being encrypted in step 68 be transmitted. The compression and encryption can be obtained from transforming the data that is in be measured in a decimal format, in a different format, for example in the hexadecimal format. This causes the number of characters to be transmitted to be reduced, thereby providing a data compression function, and also making the transmitted data (e.g., a QR code or the like) harder to decode for an unauthorized user, which provides an encryption function . More specifically, any smart device can read the QR code and obtain an alphanumeric string therefrom, without specific knowledge of the algorithm required to convert this string into data indicating the measured battery parameters, but the alphanumeric string per se is useless. In addition to the battery parameter data, an identification of the simplified battery test device 12 be transferred what in step 66 is specified. This would typically be the model and serial number of the device 12 as well as the software version that uses it.

When the battery tester of the invention is used to test a battery which is used as a battery for starting an internal combustion engine, the user may be prompted to start the internal combustion engine at this point, or he may do so after a few seconds have passed by step 70 is specified. The testing device 12 will then be like in step 72 make specified secondary measurements; as previously mentioned, these typically include the minimum voltage across the battery during start-up and the voltage and frequency of a ripple after start-up. The former indicates the state of preservation of the battery, and the latter indicates a function of a generator.

After connecting these secondary measurements, the data obtained can be used in the steps 74 and 76 can be compressed and encrypted as previously explained, and both the primary and secondary data can be used in step 78 again preferably by generating a QR code that appears on the screen 13 the testing device 12 is displayed.

It will be understood that while a QR code is currently the preferred form of code for transferring data from the simplified test device to the smart device, other forms of optical machine readable data transfer formats can be used and are accordingly within the scope of the invention . For example, a one-dimensional code such as a barcode can be used, or other forms of two-dimensional "bitmaps" similar to the QR code can be used. Accordingly, reference herein to the use of a QR code is intended to include other forms of code that are suitable for the purposes set forth herein.

5 shows the main steps taken by the smart device 14th in receiving the raw battery parameter data relating to a specific battery 10 to be tested from the simplified battery tester 12 are received, analyzing the data with reference to context parameters describing the nominal characteristics of the battery, determining the battery condition and communicating the results in a useful form.

In the step 90 Assuming that the simplified battery tester is able to display data on its screen in the form of a code, for example a QR code (possibly compressed and / or encrypted), the smart device scans 14th the QR code. As previously noted, all of the devices referred to herein as smart devices have the ability to scan QR codes and convert the QR codes to an alphanumeric string (if the appropriate app has been downloaded). This is done in the step 92 carried out. When the raw data has been compressed and / or encrypted, the smart device becomes 14th as part of the app that enables the device to function according to the invention, have downloaded the software needed to convert the QR coded data into a series of measurements.

In step 94 represents the user of the smart device 14th the context information that describes the nominal specifications of the battery and other context information that is useful in determining qualitative results. This can be done in several ways. The operator may be prompted to enter key values such as battery rating, which are normally printed on the battery; the operator can enter the battery pack number and the smart device can download the key data from the manufacturer's website; or the operator can use the smart device 14th use to acquire battery identification information from the battery, for example by scanning the bar code label on the battery to obtain the battery part number and then download the context information you need. If the test device of the invention is used to periodically test a number of identical batteries, for example in a vehicle fleet or a stationary battery bank (explained in more detail below), the context information can be permanently stored in the smart device, which eliminates the repeated input step.

In step 96 the smart device selects an appropriate algorithm to analyze the raw data using the context information. For example, it is known that batteries that are partially discharged can still be evaluated, but that different battery types require different “compensation curves”. See, for example, the McShane et al. Patent 5,821,756. By entering the battery context information, for example a part number or alternatively the battery type, battery power and the like, the smart device can select the correct algorithm for analyzing the raw data.

In step 98 the context information and the measured data are used to calculate a qualitative battery condition; for example, it is determined whether the battery is well preserved and discharged, fully charged but not in good condition, and the like. In step 100 it is determined that the battery passes or fails this test and in step 102 a recommendation is given (for example "battery ok" or "replace battery"). This information is then in step 104 displayed on the screen of the smart device.

In step 106 can use the smart device 104 used to collect additional information related to the battery; for example, when installed in a vehicle, the vehicle identification number (VIN) can be detected by scanning the label that is present in all modern vehicles. Alternatively, the information on the vehicle's license plate or the number that identifies the vehicle in a fleet can be recorded. This vehicle identification information is then stored together with the qualitative battery status information.

Finally can step in 108 the stored information can be exported, for example to a central computer of a service center or the like.

The method of using a graphical bitmap to display battery characteristics previously described can also be applied to simplified battery test circuits designed for semi-permanent attachment to batteries. In this embodiment, the simplified battery tester works 12 as a continuous battery power monitor, and the graphic image is periodically updated to reflect the most recent measurements. By scanning the device 12 at any time using a remote smart device 14th the current measurements of the battery can be recorded and analyzed, and qualitative status results can be calculated and displayed.

In the previous part of the application, an embodiment of the invention was described in which the smart device carries out, among other things, the analysis of the raw data received from the simplified test device; that is, the smart device has the algorithms needed to process the raw data and battery identification information to evaluate a battery. However, brief reference has already been made to further embodiments in which the smart device is used in different ways, the processing of the raw data being handled differently. These embodiments are described in more detail below. Additional improvements are also discussed.

In a first further embodiment, which is referred to as the “web client” embodiment, the smart device is again provided with an application program or an “app” that has software that enables the smart The device can effectively control the collection of raw data from the simplified tester, but with the raw data passed from the smart device, which functions as a "web client", to a remote computer which functions as a "web server" which analyzes the raw data and forwards the result of the test to the smart device and performs other functions such as storing the data for long-term prediction and the like. Thus, in this embodiment the smart device is again provided with software that prompts the user to scan the screen of the simplified tester to obtain raw data, scan the barcode or UPC on the battery to obtain the battery identification data, scan the vehicle identification number (VIN) and the like. This data and this information is then transmitted to the web server for analysis and further processing.

In a second further embodiment, referred to as the “web browser” embodiment, the smart device does not need to have a dedicated app. Instead, the smart device only functions as a web browser, ie when activated, for example by scanning a QR code on the simplified checking device that contains the Internet address of the web server, the smart device simply accesses the web Server, which in turn responds with a series of prompts to the user. The smart device then displays these to the user who takes the required actions and the smart device transmits the results to the web server, which in turn performs the analysis.

It will be apparent to those skilled in the art that a smart device per se is not needed for this "web browser" embodiment of the invention, since any device capable of capturing the raw data and battery identification information from the simplified battery tester will and supports a web browser function that can perform required functions.

Both further embodiments have the significant advantage that the smart device does not have to be able to carry out the analysis, but rather serves essentially to transmit raw data and battery identification information to the web server, which means that the smart device need not be provided with the specific information needed to properly analyze each of the many hundreds of different battery models on the market. Instead, this information can simply be stored in a database that is maintained in conjunction with the web server, which is easier than repeatedly updating a database for download to various smart devices as new battery models become available. The second “web browser” embodiment provides the further advantage that there is no need to provide different types of apps to support the different types of smart devices that are currently available.

In a further possible improvement, the battery can be provided with a device that forwards the battery identification data directly to the simplified battery tester, which can then transmit the data to the smart device via the QR code together with the raw data. This would greatly simplify the process of providing reliable battery identification data to the smart device for analysis as above, as well as providing the data from the smart device to the web server for analysis as in the embodiments described below. This could be achieved by installing an “RFID chip” in the battery during manufacture, which is used, for example, to identify pets and other animals. The RFID chip would be encoded to transmit an identification of the battery to a corresponding RFID receiver provided in the simplified battery tester.

Thus, according to this aspect of the invention, a web-based battery diagnostic system is provided. In a first “web client” embodiment, a smart device running a specially developed app is used to acquire raw test data from a simplified test device. The app can be configured to collect battery identification data by scanning a battery UPC code or more detailed information, including a unique ID or a barcode, through RFID or user input, and can also contain application identification information such as a VIN code in the vehicle context or other application identification information such as an identification of a test location.

The raw test data and the battery identification information and the application identification information are then transmitted from the smart device to a remote computer which functions as a web server and is equipped with analysis protocols and algorithms for calculating results and diagnoses based on the data provided. The web server returns these results to the smart device for presentation to the user.

In a second “web browser” embodiment, the user accesses a remote web server using the smart device as a web browser, or uses a separate device that can serve as a web browser, such as a personal computer . The web server is designed with analysis protocols and algorithms for calculating results and diagnoses based on the data provided. The smart device receives raw test data from the simplified test device, as well as battery identification information, and makes this available directly to the web server, optionally together with “application identification information”. Such application identification information can describe the specific application in which the battery is used, for example starting an automobile, as a backup in industry, as a backup in telecommunications, in an electric or hybrid vehicle, or in a marine deep cycle. Such information can be used to tailor the context information that is collected and the algorithms that are used to determine battery status. The web server uses stored analysis protocols and algorithms and calculates results and diagnoses based on the data provided. The results are displayed to the user in the browser.

In the first "web client" embodiment, the software on the smart device can be very simple and does not need to be updated frequently because the battery analysis algorithm resides on the web server; at the second "web Browser "embodiment, dedicated software / applications on the smart device can be completely eliminated. A major advantage of either embodiment is that the analysis software and battery information database are in a central location and can be updated and managed with minimal complexity. Furthermore, in particular with the “web browser” embodiment, the need to use software applications for different mobile operating systems such as iOS, Android, Symbian, Windows 8th , etc. to develop and maintain, eliminated.

According to another aspect of the invention, a battery tester is provided which is capable of providing useful test results without a user having to enter data. In this case, a simplified battery tester is connected to a battery and, after a specific time delay, an automatic test routine for measuring battery parameters begins. The user does not have to enter anything into the simplified test device. The simplified test device automatically records data and displays the data in machine-readable form, for example as a QR code, and optionally in a form that can be read by a user.

As mentioned previously, in previously used battery testers, the user had to read battery context information such as test parameters from the battery label and enter this data into the test device. However, this process was flawed as the user may not read the information, read it incorrectly, or make mistakes when entering data into the data validator. According to an important aspect of the invention, the smart device is designed to digitally record the battery identification information. This battery identification information could be in the form of a UPC code or other optically readable code, or it could be provided by an RFID chip built into the battery at manufacture.

If the battery identification information is to be supplied by means of an RFID chip, then the simplified battery test device, which will have an RFID receiver in this embodiment, will be designed to automatically detect the RFID information of the battery immediately after the test device has been connected to the battery. The simplified test device will display on its display the battery identification information that was captured by the RFID transmission together with the raw data, for example by means of a QR code.

The smart device will again capture the battery identification information from the optical code on the battery label or from the RFID tag after it has been identified by the simplified test device along with the raw battery test data. Additionally, the smart device can capture vehicle or application identification information, for example using a VIN scan. The battery and vehicle identification information is used by the smart device to look up the appropriate context values and specific test variables so that a full and comprehensive battery test and diagnosis can be performed. The database of battery context information and test parameters can be stored in the smart device or on a web server that is dynamically accessed to look up the battery analysis parameters in a database and to communicate the critical parameters to the smart device.

Together, these functions enable a comprehensive test of a battery with specific battery test parameters without a user having to enter data. This eliminates human error and attempted fraud and increases inspection speed.

These embodiments of the invention will now be discussed in detail with reference to the accompanying drawings.

As previously explained, shows 6th a schematic of the components used for the new “web client” embodiment and the new “web browser” embodiment of the invention. 7th Figure 12 shows a flow chart of the steps of the "web client" embodiment, and 8th Figure 12 shows a flow diagram of the steps of the "web browser" embodiment. 9 FIG. 13 is a flow chart of a modification of the process of FIG 8th .

6th shows a simplified battery tester 120 that with a battery 122 through wires 126 connected is. The test device 120 performs appropriate tests as previously described to generate raw data that can be analyzed to determine the condition of the battery, and generates a QR code as shown 124 . This is then through a smart device 128 read. The smart device 128 will then typically prompt the user for the VIN or other machine readable code indicating the vehicle or other contextual information what with 130 and the battery identification information via a bar code, UPC or other machine readable code, what with 132 is designated to scan.

Optionally, the battery identification information can be obtained from an RFID chip 134 provided which is provided in the manufacture of the battery. This could be used to provide a unique identification of each battery, which could be very valuable. As is known, such an RFID chip transmits 134 a unique identification code when addressed by a nearby RFID receiver. This addressing can be done and the battery identification information obtained from an RFID receiver 136 , the part of the simplified battery tester 120 is detected and added to the raw data can be included as part of the QR code 134 to the smart device 128 be transmitted.

The raw data and the battery identification information are then stored by the smart device 128 as in 140 shown over the internet to a web server 138 transfer. In this step the smart device works 128 as a web client. Ie the software app running on the smart device 128 running, assigns the internet address of a web server 138 so that the raw data and the battery identification information are transmitted to it. The web server then pulls one or more databases 142 , 144 to determine the correct battery characteristics, perform the analysis and send the result back to the smart device 128 for an appropriate action.

7th Figure 12 shows a flow chart of these steps for the first "web client" embodiment in which the smart device 128 has an app that causes the smart device to provide instructions to the user, the battery tester, as needed 120 Scan to get the QR code, scan the battery bar code, scan the VIN number, etc. Thus, the user starts in a first step 150 the application. In an optional step 152 the user will be prompted to scan or enter the VIN with the smart device. In a second optional step 154 the user is prompted to scan the battery identification code (which could be the UPC or a separately provided barcode or the like) with the smart device. If the battery has an RFID chip, the simplified battery tester can 120 determine the battery identification from it, so that the user does not have to enter anything to ensure that this data is correctly recorded. Other data, for example the location of the test, can be entered in step 156 can be entered.

The battery tester 120 is already connected to the battery or is in step 158 connected to the same. The test device 120 then leads in step 160 the automatic test routine and shows in step 162 the raw data (and the RFID battery identification data, if the battery and battery tester are equipped accordingly). The user will then step in 164 prompted to scan the QR code to receive the raw data. The smart device, which serves as a web client, then presents in step 166 a connection to a remote computer 138 that serves as a web server and transfers in step 168 the raw data along with the battery identification information, VIN and other collected data to the server 138 . The server then intervenes in step 170 to the database to find the appropriate battery information, for example its performance, the standard to which the performance relates, and one or more coefficients that are required to convert measured raw data into standardized battery power units such as CCA, CA, ampere-hours, etc., to determine. These coefficients contain the previously mentioned values, which differ significantly for batteries of different construction classes and for batteries within these classes, especially within the AGM class. The server then performs in step 172 the algorithm for determining the battery condition and transmits in step 174 the result to the smart device. The smart device then shows in step 176 the result to a user for appropriate action.

As previously explained, it is particularly difficult to test batteries that are located in remote or inaccessible spaces in the vehicle. Batteries are often located under a seat or in a remote location that is not easily accessible. In this case, remote battery terminals are provided in a position that is easily accessible so that jump-starting or battery diagnostic procedures can be performed. However, ohmic tests of a battery made on the remote terminals are corrupted due to the resistance created by the connections between the battery and the remote terminals used for testing. If the resistance of the particular design is known, then an adjustment of the test results can be made to obtain an accurate diagnosis. Database 142 , 144 ( 6th ) may have such adjustment factors for each vehicle, and when the VIN is scanned, the smart device or web server in step 170 look up and apply the appropriate adjustment factor so that a highly accurate test result is obtained.

8th Fig. 10 shows a second "web browser" embodiment in which the smart device is merely used as a web browser or in which the smart device per se is replaced by another device that provides the necessary data entry. and has communication skills, such as a personal computer.

Any reference in the following to a smart device is to be understood to include the latter possibility.

In step 200 the user starts the web browser function on the smart device and uses it in step 202 to access a specific web server. In step 204 the web server starts a web application program that has the battery test and analysis routine and begins a test session for the web browser by sending a dynamic web form and appropriate instructions to the web browser in step 206 . The user then sees the form on the browser screen and completes it in step 208 , typically by capturing the QR code from the simplified verification device (used as previously with respect to 7th described in step 158 connected to the battery in step 160 has carried out the test routine and in step 162 has displayed the raw data), capturing a barcode, UPC or RFID code that identifies the battery, capturing the VIN code if provided, or manually entering the above or any other required information into the web form. The smart device then carries the completed form in step 210 back to the web server.

The web application then analyzes in step 212 the data returned and sends in step if necessary 214 another request. After all the required information has been collected, the web application analyzes the returned data, closes in step 216 the diagnosis and sends in step 218 the test report for the browser. This one is in step 220 received and the user can take appropriate action.

With an alternative that is in 9 shown, the simplified battery tester 120 be provided with the Internet address of the web server. Testing would then involve connecting the simplified battery tester 120 with the battery 122 in step 240 begin; the simplified battery tester 120 would then step in 242 perform the test and in step 244 Display a QR code (or an equivalent) with the raw data and the internet address of the server and the battery identification information if the battery is equipped with an RFID chip. In step 250 Then the user would simply enter the QR code with the smart device 128 scan, which automatically uses the address contained in the code, in step 252 open a browser session with the web server. The smart device 128 would then use the internet address to communicate with the web server, and the process would essentially be as before in connection with 8th described completed, the steps are labeled similarly. The step 254 differs from step 208 in 8th in that the data image is already in step 250 has been captured.

The previously described method of using a smart device as a web browser and sending battery test data to the web server can also be used with devices that are primarily used for other diagnostic purposes, ie as opposed to smartphones, tablet computers and the like . For example, various “workshop diagnostic platforms” can be used, essentially tablet computers with specific test software and suitable connection components and cables that are used in workshops for diagnosing and repairing vehicles.

Some of these workshop diagnostic devices differ from smart devices per se in that they do not have components and software for optically acquiring data, i.e. they are not able to read, for example, a QR code from a simplified test device. In such cases, the simplified test device is connected to the workshop diagnostic platform in the manner described below through the existing wiring of the vehicle. The workshop diagnostic platform can then be used to carry out battery diagnosis or to carry out either the web client embodiment or the web browser embodiment of the present invention. With this configuration, various information, for example the VIN or other data, will be available for the workshop diagnostic platform on the basis of previously performed test procedures, for example on the basis of an on-board diagnostic scan being carried out and information being extracted from the vehicle computer. In this case, some of the information needed to perform the battery test algorithm can be shared between the vehicle diagnostic application and the battery test procedures, allowing testing with less user interaction.

The arrangement of the components required to use the workshop diagnostic platform for the alternative described above is shown schematically in 10 shown. The simplified battery tester 306 is with a battery 302 connected that in a vehicle 300 is built in. The battery tester 306 is via a wire connection 304 that is typical of electrical battery testers, such as a pair of Kelvin connections, to the battery 302 connected. At the in 10 embodiment shown can Battery tester 306 one or more methods of outputting battery test data and other data provided by the simplified battery test device 306 are obtained, implement. So that it can also be used for other applications (as described above), the test device 306 an optical output device such as a screen for displaying a QR code 308 , a radio communication link 312 for Bluetooth, WiFi or other radio processes or a DC power communication device 310 exhibit. The DC power communication device 310 uses a hardwired connection 304 for sending battery test data and other data over the DC wiring 314 of the vehicle 300 . That way, a recipient can 318 connected to the vehicle's DC wiring will receive the battery test data. The in 10 Example shown, this receiver could have an OBD interface 318 a workshop diagnostic platform 324 be. The OBD interface 318 is connected to the OBD port 316 with the vehicle DC wiring 314 connected. Thus the workshop diagnostic platform could 324 the battery test data via a wired connection 320 , an optical image sensor or the like via the OBD port 316 receive.

Even if in this embodiment the OBD port 316 is used to access vehicle DC power wiring, the transmission of information does not involve the vehicle computer or OBD system. Rather, the OBD port points 316 one pin that is connected to the positive terminal of the battery via the vehicle wiring, and another pin that is connected to the vehicle ground, which is connected to the negative terminal of the battery. A digital message with the test results and associated data is simply transmitted and effectively superimposed on the (nominal) 12 volts across the battery terminals. In this way, the DC communication of the test data can be performed without consulting the vehicle computer system. Also when using the vehicle OBD port 316 For use with vehicle DC power wiring, a DC communications receiver could be advantageous 318 at a different point in the vehicle DC power wiring 314 get connected.

Alternatively, the workshop diagnostic platform 324 if properly equipped, the battery test data using an image sensor and capturing an image on the display screen 308 of the simplified battery tester 306 as described above, or could receive the battery test data via a radio receiver 322 through direct communication with the radio transmitter 312 receive.

The workshop diagnostic platform 324 can then essentially take over the function of the smart device described above, ie have a user interface and directly run a battery diagnostic software. Alternatively, the workshop diagnostic platform 324 be able to at 326 Establish an Internet connection and, as previously described, can download battery test data and other vehicle data from the OBD interface 318 to a remote server 328 send, according to either the web client embodiment or the web server embodiment of the present invention.

In this embodiment, the simplified battery tester can provide battery test data to a diagnostic tool that is already in use in the shop, thereby reducing the number of tools a technician must use. Using the Internet to communicate with a web server that has the analysis software, the diagnostic tool can also be simplified.

11 shows the steps taken by the workshop diagnostic platform 324 (in 11 referred to as a "diagnostic tool") to perform the method of the present invention. As mentioned earlier, this is the simplified battery tester 306 in step 350 connected to the battery leads in step 352 the check routine, generates the raw data and optionally a web server address and gives this information in step 356 out. The workshop diagnostic platform connected to the vehicle's OBD port 324 leads in step 358 pass the test and then receive in step 360 the battery test data and takes action in step 362 the available context information such as the VIN from the vehicle computer via the OBD port. The workshop diagnostic platform 324 then performs the steps in step necessary to analyze the data to characterize the battery 364 out.

This can be done in one of the three ways previously described. The workshop diagnostic platform 324 can in step 368 perform the analysis yourself; this corresponds to the first embodiment in which the smart device does not contact a web server. Alternatively, the workshop diagnostic platform 324 in step 366 follow the “web client” approach, in which the workshop diagnostic platform 324 Has software that prompts the user to complete the various input steps as in 7th perform; or she can step in 370 the “web browser” approach of 8th and 9 where the web server essentially controls the collection of data as needed. In both the "web client" approach and the "web browser" approach, the web server carries out the battery analysis described above. In any case will be presented to the user in step 372 the results of the examination are communicated.

Thus, a device that is sold as a workshop diagnostic platform or the like and that differs from a smartphone or a tablet computer that is not intended for use in a workshop can still be classified as a “smart device” within the meaning of the following claims be understood if it has the necessary functions.

While the invention has been described in connection with testing a vehicle battery, it can be used in other battery testing applications. For example, it is common to use large rows of "stationary" batteries to provide backup power for emergency power to traffic lights, hospitals, telecommunications facilities, and other critical facilities. Such rows of batteries are usually kept fully charged so that the question of whether batteries are possibly discharged does not usually arise. However, such batteries lose storage capacity over time and accordingly it is important to monitor their deterioration. This is usually achieved through the ohmic measurements given above.

In accordance with the invention, the complex and expensive battery testers currently in use, which typically include test circuitry for making such ohmic measurements in conjunction with a user interface to enable the user to enter a battery identification number or the like, a memory for storing the results for each Battery, communication means for transmitting reports to a central computer which monitors the results, and the like can be replaced by the simplified battery testing device and the smart device according to the invention.

In such use, the simplified battery tester would 12 Connected in turn to each battery under test and performed the basic ohmic measurement explained above, that is, measure the internal resistance of the battery. This would then become the smart device as described above 14th transferred, and the smart device 14th would also be used as explained above to analyze the raw data to evaluate the battery against a standard for batteries of this type and record the result along with an identification of the battery. The results for a large number of batteries that were tested could then be downloaded to a central computer, printed out, or the like.

Alternatively, or in addition, results of a battery test on a day may be compared to previous test results for the same battery to determine trends. The battery test results can be stored in the smart device or stored in a remote database that the smart device can dynamically access. In this way, using any of the battery identifiers discussed above, the operator can identify a battery that has already been tested. After the battery has been identified, the current test results are automatically compared to the previous test results to provide information on a rate of deterioration of the battery.

Finally, as previously mentioned, the test apparatus of the invention is not limited to testing a battery, but can be used in testing many different types of devices, devices or components. In any event, as previously mentioned, the simplified test fixture would be provided with suitable components for connecting the microprocessor control unit (MCU) of a test fixture to the circuitry of the device, device or component to be tested, and the MCU would be provided with suitable software programmed, for example, to perform a physical measurement of a value (as in the embodiment for testing a battery), to query an internal memory (as in the OBD example), the identification of the tested item (as in the use of an RFID chip described above ) or the like. The simplified test device would then transmit this information to an associated smart device for analysis and for taking appropriate action.

In addition to using test devices according to the invention in testing a battery or downloading OBD data, there are numerous applications for test devices according to the invention, both in and outside of the automotive industry. For example, telecommunications equipment is usually tested using test equipment that measures parameters such as a data rate to verify that the subscriber is receiving the promised service. Such test devices are currently usually integrated, as previously described; that is, they include circuitry for applying a test signal to the device and measuring a response thereof, as well as a microprocessor with suitable software for analyzing the results, receiving operator input through a user interface and reporting the results. As previously explained, according to the invention, an integrated test device can be replaced by a simplified test device for performing the basic test operation and for passing on the raw data resulting therefrom to a suitably programmed smart device for analysis, user input, dissemination of results and the like.

Accordingly, the principle of operation of the simplified tester of the invention can be broadly understood as obtaining data indicating the condition of the device, device or component to be tested, including measuring a value (as in the case of a battery), downloading stored data Data (e.g. downloading data indicating the condition of a vehicle from its OBD port) or feeding a signal into a circuit and measuring its response (e.g. when testing a telecommunication device) and transmitting the data obtained in this way to the smart Device are described. As previously discussed, the smart device provided with the appropriate software (typically by downloading a software app provided by the manufacturer of the particular test device) then determines the state of the device, device or component based on the data received. As previously described, the data analysis function can alternatively be performed by a web server in response to data passed from the smart device.

Therefore, even if several preferred embodiments of the invention have been described in detail, numerous improvements and extensions are within the knowledge of the person skilled in the art and accordingly fall within the scope of the invention, unless they are excluded by the following claims.

It is explicitly emphasized that all features disclosed in the description and / or the claims are viewed as separate and independent of one another for the purpose of the original disclosure as well as for the purpose of limiting the claimed invention, regardless of the combinations of features in the embodiments and / or the claims should. It is explicitly stated that all range specifications or specifications of groups of units disclose every possible intermediate value or subgroup of units for the purpose of the original disclosure as well as for the purpose of restricting the claimed invention, in particular also as a limit of a range specification.
