Definitions
- the present disclosure relates generally to monitoring of energy storage devices.
- Lead acid energy storage devices are prevalent and have been used in a variety of applications for well over 100 years. In some instances, these energy storage devices have been monitored to assess a condition of the energy storage device. Nevertheless, these prior art monitoring techniques typically are complex enough and sufficiently costly as to limit their use, and to limit the amount of data that is obtained, particularly in low value remote applications. For example, there is generally insufficient data about the history of a specific energy storage device over the life of its application. Moreover, in small numbers, some energy storage devices are coupled to sensors to collect data about the energy storage system, but this is not typical of large numbers of devices and/or in geographically dispersed systems. Often the limited data obtained via prior art monitoring is insufficient to support analysis, actions, notifications and determinations that may otherwise be desirable.
- a battery monitor circuit for monitoring a battery is located external to the battery and wired electrically to the battery.
- the battery monitor circuit comprises: a voltage sensor for connecting electrically to the battery for monitoring a voltage between a positive terminal and a negative terminal of the battery.
- the battery comprises a single monobloc or a plurality of monoblocs that are electrically connected in series or parallel, and each monobloc comprises at least one electrochemical cell.
- the battery monitor circuit further comprises a temperature sensor for monitoring a temperature of the battery, a processor for receiving a monitored voltage signal from the voltage sensor, for receiving a monitored temperature signal from the temperature sensor, for processing the monitored voltage signal and the monitored temperature signal, and for generating voltage data and temperature data based on the monitored voltage signal and the monitored temperature signal, and a memory for storing the voltage data and the temperature data.

- the intelligent energy storage system further comprises a remote display for receiving data, information, and notifications from the remote device and for providing notifications associated with the plurality of batteries based on analysis of the voltage data and the temperature data received by the remote device from the first portion of the plurality of batteries and the second portion of the plurality of batteries.
- a method of remotely monitoring a battery comprises sensing, using a battery monitor circuit disposed externally to the battery and coupled to a positive terminal and a negative terminal of the battery, a voltage of the battery with a voltage sensor; recording the voltage and a timestamp for the voltage in a storage medium of the battery monitor circuit; sensing, via a temperature sensor of the battery monitor circuit, a temperature of the battery; recording the temperature and a timestamp for the temperature in the storage medium; generating, using a processor of the battery monitor circuit, voltage data and temperature data based on the recorded voltage and the recorded temperature; and wirelessly transmitting, using a transceiver of the battery monitor circuit, the voltage data, the temperature data, the voltage timestamp, and the temperature timestamp recorded in the storage medium (collectively, “battery operating data”) to a remote device.

- the battery 100 / 200 may be configured to communicate a unique electronic identifier (unique serial number, or the like) from the battery monitor circuit 120 to the remote device, the cellular network 418 , or the locally located remote device 414 .
- This serial number may be correlated with a visible battery identifier (e.g., label, barcode, QR code, serial number, or the like) visible on the outside of the battery, or electronically visible by means of a reader capable of identifying a single battery in a group of batteries. Therefore, the system 400 may be configured to associate battery data from a specific battery with a unique identifier of that specific battery.
- an installer may enter into a database associated with system 400 various information about the monobloc, for example relative position (e.g., what battery, what string, what position on a shelf, the orientation of a cabinet, etc.). Similar information may be entered into a database regarding a battery 100 .
- the data indicates a battery of interest (for example, one that is performing subpar, overheating, discharged, etc.)
- that particular battery can be singled out for any appropriate action.
- a user can receive information about a specific battery (identified by the unique electronic identifier), and go directly to that battery (identified by the visible battery identifier) to attend to any needs it may have (perform “maintenance”). For example, this maintenance may include removing the identified battery from service, repairing the identified battery, charging the identified battery, etc.
- a battery 100 / 200 may be noted as needing to be re-charged, a warehouse employee could scan the batteries on the shelves in the warehouse (e.g., scanning a QR code on each battery 100 / 200 ) to find the battery of interest and then recharge it.
- the locally located remote device 414 can be configured to retrieve the data on that specific battery, including the unique electronic identifier, voltage and temperature, and alert if some action needs to be taken with respect to it (e.g., if the battery needs to be recharged before shipment).
- the battery monitor circuit 120 itself, the remote device and/or any suitable storage device can be configured to store the battery operation history of the individual battery 100 / 200 through more than one phase of the battery's life.
- the history of the battery can be recorded.
- the battery may further record data after it is integrated into a product or placed in service (alone or in a battery). The battery may record data after it is retired, reused in a second life application, and/or until it is eventually recycled or disposed.
- the historical data is stored remotely from the battery monitor circuit 120 .
- the data described herein can be stored in one or more databases remote from the battery monitor circuit 120 (e.g., in a cloud-based storage offering, at a back-end server, at the gateway, and/or on one or more remote devices).
- the system 400 may be configured to store, during one or more of the aforementioned time periods, the history of how the battery has been operated, the environmental conditions in which it has been operated, and/or the society it has kept with other batteries, as may be determined based on the data stored during these time periods.
- the remote device may be configured to store the identity of other batteries that were electrically associated with the battery 100 / 200 , such as if two batteries are used together in one application. This shared society information may be based on the above described unique electronic identifier and data identifying where (geographically) the battery is located.
- the remote device may further store when the batteries shared in a particular operation.
- time may include the date, hour, minute, and/or second of a voltage/temperature measurement. In another exemplary embodiment, “time” may mean the amount of time that the voltage/temperature condition existed.
- the history is not based on data derived from the charge and discharge currents associated with the battery(s). This is particularly significant because it would be very prohibitive to connect to and include a sensor to measure the current for each and every monobloc, and an associated time each was sensed from the individual battery, where there is a large number of monoblocs.
- system 400 may be in communication with an external battery management system (BMS) coupled one or more batteries 100 / 200 , for example over a common network such as the Internet.
- BMS battery management system
- System 400 may communicate information regarding one or more batteries 100 / 200 to the BMS and the BMS may take action in response thereto, for example by controlling or modifying current into and/or out of one or more batteries 100 / 200 , in order to protect batteries 100 / 200 .
- the system in contrast to past solutions, is configured to store contemporaneous voltage and/or contemporaneous temperature data relative to geographically dispersed batteries. This is a significant improvement over past solutions where there is no contemporaneous voltage and/or contemporaneous temperature data available on multiple monoblocs or batteries located in different locations and operating in different conditions.
- historical voltage and temperature data is used to assess the condition of the monoblocs or batteries and/or make predictions about and comparisons of the future condition of the monobloc or battery.
- the battery monitor circuit 120 is located such that it is viewable/accessible from the outside of battery 100 / 200 .
- battery monitor circuit 120 is located external to the battery 100 / 200 in a location that will measure the external temperature of the battery 100 / 200 .
- the battery monitor circuit 120 may measure the temperature in between two or more monoblocs, the outer casing temperature of a monobloc, or the air temperature in a battery containing multiple monoblocs.
- a battery 100 / 200 having a battery monitor circuit 120 coupled thereto may be coupled to a load and/or to a power supply.
- battery 100 / 200 may be coupled to a vehicle to provide electrical energy for motive power.

The contents of each of the foregoing applications are hereby incorporated by reference for all purposes (except for any subject matter disclaimers or disavowals, and except to the extent that the incorporated material is inconsistent with the express disclosure herein, in which case the language in this disclosure controls).
- The present disclosure relates generally to monitoring of energy storage devices.
- Lead acid energy storage devices are prevalent and have been used in a variety of applications for well over 100 years. In some instances, these energy storage devices have been monitored to assess a condition of the energy storage device. Nevertheless, these prior art monitoring techniques typically are complex enough and sufficiently costly as to limit their use, and to limit the amount of data that is obtained, particularly in low value remote applications. For example, there is generally insufficient data about the history of a specific energy storage device over the life of its application. Moreover, in small numbers, some energy storage devices are coupled to sensors to collect data about the energy storage system, but this is not typical of large numbers of devices and/or in geographically dispersed systems. Often the limited data obtained via prior art monitoring is insufficient to support analysis, actions, notifications and determinations that may otherwise be desirable. Similar limitations exist for non-lead-acid energy storage devices. In particular, these batteries, due to their high energy and power have entered various new mobile applications that are not suitable for traditional monitoring systems. Accordingly, new devices, systems and methods for monitoring energy storage devices (and batteries in particular) remain desirable, for example for providing new opportunities in managing one or more energy storage devices, including in diverse and/or remote geographic locations.
- In an example embodiment, a battery monitor circuit for monitoring a battery is located external to the battery and wired electrically to the battery. The battery monitor circuit comprises: a voltage sensor for connecting electrically to the battery for monitoring a voltage between a positive terminal and a negative terminal of the battery. The battery comprises a single monobloc or a plurality of monoblocs that are electrically connected in series or parallel, and each monobloc comprises at least one electrochemical cell. The battery monitor circuit further comprises a temperature sensor for monitoring a temperature of the battery, a processor for receiving a monitored voltage signal from the voltage sensor, for receiving a monitored temperature signal from the temperature sensor, for processing the monitored voltage signal and the monitored temperature signal, and for generating voltage data and temperature data based on the monitored voltage signal and the monitored temperature signal, and a memory for storing the voltage data and the temperature data. The voltage data represents the voltage between the positive terminal and the negative terminal of the battery, and the temperature data represents a temperature of the battery. The battery monitor circuit further comprises an antenna, and a transmitter for wirelessly communicating the voltage data and the temperature data to a remote device via the antenna.
- In another example embodiment, an intelligent energy storage system comprises a plurality of batteries, each battery electrically connected to a respective battery monitor circuit disposed externally to the battery. A first portion of the plurality of batteries are remotely dispersed from a second portion of the plurality of batteries, and the plurality of batteries are associated with at least one remote device for remotely receiving, via wireless data transmission, voltage data and temperature data from each of the plurality of batteries. The intelligent energy storage system further comprises a remote display for receiving data, information, and notifications from the remote device and for providing notifications associated with the plurality of batteries based on analysis of the voltage data and the temperature data received by the remote device from the first portion of the plurality of batteries and the second portion of the plurality of batteries.
- In another example embodiment, a method of remotely monitoring a battery comprises sensing, using a battery monitor circuit disposed externally to the battery and coupled to a positive terminal and a negative terminal of the battery, a voltage of the battery with a voltage sensor; recording the voltage and a timestamp for the voltage in a storage medium of the battery monitor circuit; sensing, via a temperature sensor of the battery monitor circuit, a temperature of the battery; recording the temperature and a timestamp for the temperature in the storage medium; generating, using a processor of the battery monitor circuit, voltage data and temperature data based on the recorded voltage and the recorded temperature; and wirelessly transmitting, using a transceiver of the battery monitor circuit, the voltage data, the temperature data, the voltage timestamp, and the temperature timestamp recorded in the storage medium (collectively, “battery operating data”) to a remote device.
- The contents of this section are intended as a simplified introduction to the disclosure, and are not intended to limit the scope of any claim.

While these embodiments are described in sufficient detail to enable those skilled in the art to practice the principles of the present disclosure, it should be understood that other embodiments may be realized and that logical, mechanical, chemical, and/or electrical changes may be made without departing from the spirit and scope of principles of the present disclosure. Thus, the detailed description herein is presented for purposes of illustration only and not of limitation. For example, the steps recited in any of the method descriptions may be executed in any suitable order and are not limited to the order presented.
- Moreover, for the sake of brevity, certain sub-components of individual components and other aspects of the system may not be described in detail herein. It should be noted that many alternative or additional functional relationships or physical couplings may be present in a practical system, for example a battery monitoring system. Such functional blocks may be realized by any number of suitable components configured to perform specified functions.
- Principles of the present disclosure improve the operation of a battery, for example by eliminating monitoring components such as a current sensor which can drain a battery of charge prematurely. Moreover, principles of the present disclosure improve the operation of various computing devices, such as a mobile communications device and/or a battery monitor circuit, in numerous ways, for example: reducing the memory utilized by a battery monitor circuit via compact storage of battery history information in a novel matrix-like database, thus reducing manufacturing expense, operating current draw, and extending operational lifetime of the battery monitor circuit; facilitating monitoring and/or control of multiple monoblocs via a single mobile communications device, thus improving efficiency and throughput; and reducing the amount of data transmitted across a network linking one or more batteries and a remote device, thus freeing up the network to carry other transmitted data and/or to carry data of relevance more quickly, and also to significantly reduce communications costs.
- Additionally, principles of the present disclosure improve the operation of devices coupled to and/or associated with a battery, for example a cellular radio base station, an electric forklift, an e-bike, and/or the like.
- Yet further, application of principles of the present disclosure transform and change objects in the real world. For example, as part of an example algorithm, lead sulfate in a lead-acid monobloc is caused to convert to lead, lead oxide, and sulfuric acid via application of a charging current, thus transforming a partially depleted lead-acid battery into a more fully charged battery. Moreover, as part of another example algorithm, various monoblocs in a warehouse may be physically repositioned, recharged, or even removed from the warehouse or replaced, thus creating a new overall configuration of monoblocs in the warehouse.
- It will be appreciated that various other approaches for monitoring, maintenance, and/or use of energy storage devices exist. As such, the systems and methods claimed herein do not preempt any such fields or techniques, but rather represent various specific advances offering technical improvements, time and cost savings, environmental benefits, improved battery life, and so forth. Additionally, it will be appreciated that various systems and methods disclosed herein offer such desirable benefits while, at the same time, eliminating a common, costly, power-draining component of prior monitoring systems—namely, a current sensor. Stated another way, various example systems and methods do not utilize, and are configured without, a current sensor and/or information available therefrom, in stark contrast to nearly all prior approaches.

Yet further, the battery monitor circuit may comprise an antenna and a transceiver, for example for wirelessly communicating data, such as the voltage data and the temperature data to a remote device, and for receiving data and/or instructions. Alternatively, the battery monitor circuit may include a wired connection to a remote device, for example for communicating the voltage data and the temperature data to a remote device via the wired connection, and/or for receiving data and/or instructions. In one exemplary embodiment, the battery monitor circuit transmits the voltage data and the temperature data wirelessly via the antenna to the remote device. In another exemplary embodiment, the battery monitor circuit transmits the voltage data and the temperature data via a wired connection to the remote device. The battery monitor circuit may also comprise a GPS receiver for receiving global positioning signals. In an exemplary embodiment, the battery monitor circuit is configured to be located external to the battery and wired electrically to the battery.

Thebattery 100 may further comprise apositive terminal 101 and anegative terminal 102. The sealed case may have openings through which thepositive terminal 101 andnegative terminal 102 pass. - With reference now to
FIG. 2 , abattery 200 may comprise a plurality of electrically connected monoblocs, forexample batteries 100. The monoblocs in thebattery 200 may be electrically connected in parallel and/or series. In an exemplary embodiment, thebattery 200 may comprise at least one string of monoblocs. In an exemplary embodiment, a first string may comprise a plurality of monoblocs electrically connected in series. In another exemplary embodiment, a second string may comprise a plurality of monoblocs electrically connected in series. If there is more than one string of monoblocs in the battery, the first, second, and/or additional strings may be electrically connected in parallel. A series/parallel connection of monoblocs may ultimately be connected to apositive terminal 201 and anegative terminal 202 of thebattery 200, for example in order to achieve a desired voltage and/or current characteristic or capability forbattery 200. Thus, in an exemplary embodiment, abattery 200 comprises more than one monobloc. Abattery 200 may also be referred to herein as a power domain. - The
battery 200 may have a cabinet orhousing 210. For example, thebattery 200 may comprise thermal and mechanical structures to protect the battery and provide a suitable environment for its operation. - With reference now to
FIGS. 1 and 2 , in an example application, abattery 100/200 may be used for back-up power (also known as an uninterrupted power supply or UPS). Moreover, thebattery 100/200 may be used in a cellular radio base station application and may be connected to a power grid (e.g., to alternating current via a rectifier/inverter, to a DC microgrid, and/or the like). In another exemplary embodiment, thebattery 100/200 is connected to an AC power grid and used for applications such as peak shaving, demand management, power regulation, frequency response, and/or reactive power supply. In another exemplary embodiment, thebattery 100/200 is connected to a drive system providing motive power to various vehicles (such as bicycles), industrial equipment (such as forklifts), and on-road light, medium and heavy-duty vehicles. In other example applications, thebattery 100/200 may be used for any suitable application where energy storage is desired on a short or long-term basis. Thebattery 100/200 may be shipped in commerce as a unitary article, shipped in commerce with other monoblocs (such as on a pallet with many other monoblocs), or shipped in commerce with other monoblocs as part of a battery (for example,multiple batteries 100 forming a battery 200). - In an exemplary embodiment, a
battery monitor circuit 120 may be connected to thebattery 100. In an exemplary embodiment, a singlebattery monitor circuit 120 may be associated with a single monobloc (see battery 100), as illustrated inFIG. 1 . In another exemplary embodiment, a singlebattery monitor circuit 120 may be associated with asingle battery 200, as illustrated inFIG. 2 . In another exemplary embodiment, more than onebattery monitor circuit 120 is connected to a single battery. For example, a first battery monitor circuit could be connected to a first monobloc of the battery and a second battery monitor circuit could be connected to a second monobloc of the battery. - The
battery monitor circuit 120 may comprise avoltage sensor 130, atemperature sensor 140, aprocessor 150, atransceiver 160, anantenna 170, and a storage medium or memory (not shown in the Figures). In an exemplary embodiment, abattery monitor circuit 120 is configured to sense a voltage and temperature associated with a monobloc orbattery 100/200, to store the sensed voltage and temperature in the memory together with an associated time of these readings, and to transmit the voltage and temperature data (with their associated time) from thebattery monitor circuit 120 to one or more external locations. - In an exemplary embodiment, the
voltage sensor 130 may be electrically connected by a wire to apositive terminal 101/201 of thebattery 100/200 and by a wire to anegative terminal 102/202 of thebattery 100/200. In an exemplary embodiment, thevoltage sensor 130 is configured to sense a voltage of thebattery 100/200. For example, thevoltage sensor 130 may be configured to sense the voltage between thepositive terminal 101/201 and thenegative terminal 102/202. In an exemplary embodiment, thevoltage sensor 130 comprises an analog to digital converter. However, any suitable device for sensing the voltage of thebattery 100/200 may be used. - In an exemplary embodiment, the
temperature sensor 140 is configured to sense a temperature measurement of thebattery 100/200. In one exemplary embodiment, thetemperature sensor 140 may be configured to sense a temperature measurement at a location on or outside of thebattery 100/200. The location where the temperature measurement is taken can be selected such that the temperature measurement primarily reflects the temperature of thebattery 100/200 itself and only indirectly, secondarily, or less significantly is influenced by neighboring batteries or environmental temperature. In various exemplary embodiments, thebattery monitor circuit 120 is configured to be located outside of thebattery 100/200, proximate tobattery 100/200, attached to thebattery 100/200, electrically connected by wire tobattery 100/200, and/or configured to move withbattery 100/200 so as to remain electrically connected to the positive and negative terminals of thebattery 100/200. - In a different exemplary embodiment, the
temperature sensor 140 may be configured to sense the temperature measurement at a location on or inside of thebattery 100/200. The location where the temperature measurement is taken can be selected such that the temperature measurement primarily reflects the temperature of thebattery 100/200 itself and only indirectly, secondarily, or less significantly is influenced by neighboring monoblocs or environmental temperature. In an exemplary embodiment, thetemperature sensor 140 comprises a thermocouple, a thermistor, a temperature sensing integrated circuit, or the like. In certain exemplary embodiments, thetemperature sensor 140 is embedded in the connection ofbattery monitor circuit 120 to the positive or negative terminal of thebattery 100/200, thus reducing the number of wired connections utilized to thebattery 100/200 to only two. - In an exemplary embodiment, the
battery monitor circuit 120 comprises a printed circuit board for supporting and electrically coupling the voltage sensor, temperature sensor, processor, storage medium, transceiver, antenna, and/or other suitable components. In another exemplary embodiment, thebattery monitor circuit 120 includes a housing (not shown). The housing can be made of any suitable material for protecting the electronics in thebattery monitor circuit 120, for example a durable plastic. The housing can be made in any suitable shape or form factor. In an exemplary embodiment, the housing ofbattery monitor circuit 120 is configured to be attached to thebattery 100/200 and may be secured, for example via adhesive, bolts, screws, clamps, and/or the like. Moreover, any suitable attachment device or method can be used to keep thebattery monitor circuit 120 constantly connected to thebattery 100/200. In another exemplary embodiment, thebattery monitor circuit 120 is not directly attached to thebattery 100/200, but is positioned adjacent to thebattery 100/200 such that it moves with the battery. For example,battery monitor circuit 120 can be coupled to the frame or body of an industrial forklift containing battery 100/200. - In an exemplary embodiment, the
battery monitor circuit 120 further comprises a real-time clock capable of maintaining time referenced to a standard time such as Universal Time Coordinated (UTC), independent of any connection (wired or wireless) to an external time standard such as a time signal accessible via a public network such as the Internet. The clock is configured to provide the current time/date (or a relative time) to theprocessor 150. In an exemplary embodiment, theprocessor 150 is configured to receive the voltage and temperature measurement and to store, in the storage medium, the voltage and temperature data associated with the time that the data was sensed/stored. In an exemplary embodiment, the voltage, temperature and time data may be stored in a storage medium in the form of a database, a flat file, a blob of binary, or any other suitable format or structure. Moreover, theprocessor 150 may be configured to store additional data in a storage medium in the form of a log. For example, the processor may log each time the voltage and/or temperature changes by a settable amount. In an exemplary embodiment, theprocessor 150 compares the last measured data to the most recent measured data, and logs the recent measured data only if it varies from the last measured data by at least this settable amount. The comparisons can be made at any suitable interval, for example every second, every 5 seconds, every 10 seconds, every 30 seconds, every minute, every 10 minutes, and/or the like. The storage medium may be located on thebattery monitor circuit 120, or may be remote. Theprocessor 150 may further be configured to transmit (wirelessly or by wired connection) the logged temperature/voltage data to a remote device for additional analysis, reporting, and/or action. In an exemplary embodiment, the remote device may be configured to stitch the transmitted data log together with the previously transmitted logs, to form a log that is continuous in time. In this manner, the size of the log (and the memory required to store it) on thebattery monitor circuit 120 can be minimized. Theprocessor 150 may further be configured to receive instructions from a remote device. Theprocessor 150 may also be configured to transmit the time, temperature and voltage data off of thebattery monitor circuit 120 by providing the data in a signal to thetransceiver 160. - In another exemplary embodiment, the
battery monitor circuit 120 is configured without a real-time clock. Instead, data is sampled on a consistent time interval controlled by theprocessor 150. Each interval is numbered sequentially with a sequence number to uniquely identify it. Sampled data may all be logged; alternatively, only data which changes more than a settable amount may be logged. Periodically, when thebattery monitor circuit 120 is connected to a time standard, such as the network time signal accessible via the Internet, the processor time is synchronized with real-time represented by the time standard. However, in both cases, the interval sequence number during which the data was sampled is also logged with the data. This then fixes the time interval between data samples without the need for a real-time clock onbattery monitor circuit 120. Upon transmission of the data log to a remote device, the intervals are synchronized with the remote device (described further herein), which maintains real time (e.g., UTC), for example synchronized over an Internet connection. Thus, the remote device is configured to provide time via synchronization with thebattery monitor circuit 120 andprocessor 150. The data stored at thebattery monitor circuit 120 or at the remote device may include the cumulative amount of time a monobloc has spent at a particular temperature and/or voltage. Theprocessor 150 may also be configured to transmit the cumulative time, temperature and voltage data from thebattery monitor circuit 120 by providing the data in a signal to thetransceiver 160. - In an exemplary embodiment, the time, temperature and voltage data for a battery may be stored in a file, database or matrix that, for example, comprises a range of voltages on one axis and a range of temperatures on a second axis, wherein the cells of this table are configured to increment a counter in each cell to represent the amount of time a battery has spent in a particular voltage/temperature state (i.e., to form a battery operating history matrix). The battery operating history matrix can be stored in the memory of
battery monitor circuit 120 and/or in a remote device. For example, and with brief reference toFIG. 4B , an example batteryoperating history matrix 450 may comprisecolumns 460, with each column representing a particular voltage or range of voltage measurements. For example, the first column may represent a voltage range from 0 volts to 1 volt, the second column may represent a voltage range from 1 volt to 9 volts, the third column may represent a voltage range from 9 volts to 10 volts, and so forth. The batteryoperating history matrix 450 may further compriserows 470, with each row representing a particular temperature (+/−) or range of temperature measurements. For example, the first row may represent a temperature less than 10° C., the second row may represent a temperature range from 10° C. to 20° C., the third row may represent a temperature range from 20° C. to 30° C., and so forth. Any suitable scale and number of columns/rows can be used. In an exemplary embodiment, the batteryoperating history matrix 450 stores a cumulative history of the amount of time the battery has been in each designated voltage/temperature state. In other words, the batteryoperating history matrix 450 aggregates (or correlates) the amount of time the battery has been in a particular voltage/temperature range. In particular, such a system is particularly advantageous because the storage size does not increase (or increases only a marginal amount) regardless of how long it records data. The memory occupied by the batteryoperating history matrix 450 is often the same size the first day it begins aggregating voltage/temperature data as its size years later or near a battery's end of life. It will be appreciated that this technique reduces, compared to implementations that do not use this technique, the size of the memory and the power required to store this data, thus significantly improving the operation of thebattery monitor circuit 120 computing device. Moreover, battery voltage/temperature data may be transmitted to a remote device on a periodic basis. This effectively gates the data, and, relative to non-gating techniques, reduces the power required to store and transmit data, reduces the size of the memory, and reduces the data transmission time. - In an exemplary embodiment, the
transceiver 160 may be any suitable transmitter and/or receiver. For example, thetransceiver 160 may be configured to up-convert the signal to transmit the signal via theantenna 170 and/or to receive a signal from theantenna 170 and down-convert the signal and provide it to theprocessor 150. In an exemplary embodiment, thetransceiver 160 and/or theantenna 170 can be configured to wirelessly send and receive signals between thebattery monitor circuit 120 and a remote device. The wireless transmission can be made using any suitable communication standard, such as radio frequency communication, Wi-Fi, Bluetooth®, Bluetooth Low Energy (BLE), Bluetooth Low Power (IPv6/6LoWPAN), a cellular radio communication standard (2G, 3G, 4G LTE, 5G, etc.), and/or the like. In an exemplary embodiment, the wireless transmission is made using low power, short range signals, to keep the power drawn by the battery monitor circuit low. In one exemplary embodiment, theprocessor 150 is configured to wake-up, communicate wirelessly, and go back to sleep on a schedule suitable for minimizing or reducing power consumption. This is desirable to prevent monitoring of the battery viabattery monitor circuit 120 from draining the battery prematurely. Thebattery monitor circuit 120 functions, such as waking/sleeping and data gating functions, facilitate accurately sensing and reporting the temperature and voltage data without draining thebattery 100/200. In one exemplary embodiment, thebattery monitor circuit 120 is powered by the battery to which it is coupled for monitoring. In other exemplary embodiments, thebattery monitor circuit 120 is powered by the grid or another power supply, for example a local battery, a solar panel, a fuel cell, inductive RF energy harvesting circuitry, and/or the like. - In some exemplary embodiments, use of a Bluetooth protocol facilitates a single remote device receiving and processing a plurality of signals correlated with a plurality of batteries (each equipped with a battery monitor circuit 120), and doing so without signal interference. This one-to-many relationship between a remote device and a plurality of batteries, each equipped with a
battery monitor circuit 120, is a distinct advantage for monitoring of batteries in storage and shipping channels. - In an exemplary embodiment,
battery monitor circuit 120 is located external to the battery. For example,battery monitor circuit 120 may be attached to the outside ofbattery 100/200. In another example,battery monitor circuit 120 is located proximate to thebattery 100/200, with thevoltage sensor 130 wired to the positive and negative terminals of thebattery 100/200. In another exemplary embodiment,battery monitor circuit 120 can be connected to thebattery 100/200 so as to move with thebattery 100/200. For example, ifbattery monitor circuit 120 is connected to the frame of a vehicle and thebattery 100/200 is connected to the frame of the vehicle, both will move together, and the voltage andtemperature monitoring sensors - In an exemplary embodiment,
temperature sensor 140 may be configured to sense a temperature of one of the terminals of a monobloc. In another exemplary embodiment,temperature sensor 140 may be configured to measure the temperature at a location or space between two monoblocs in a battery, or the air temperature in a battery containing multiple monoblocs. In this manner, the temperature sensed by thebattery monitor circuit 120 may be more representative of the temperature of thebattery 100/200 and/or the electrochemical cells therein. Moreover, thetemperature sensor 140 may be located in any suitable location outside of a monobloc or battery for sensing a temperature associated with the monobloc or battery. - Thus, with reference now to
FIG. 3 , anexemplary method 300 for monitoring abattery 100/200 comprising at least one electrochemical cell comprises: sensing a voltage of thebattery 100/200 with avoltage sensor 130 wired to the battery terminals (step 302), and recording the voltage and the time that the voltage was sensed in a storage medium (step 304); sensing a temperature associated withbattery 100/200 with a wired temperature sensor 140 (step 306), and recording the temperature and the time that the temperature was sensed in the storage medium (step 308); and wirelessly transmitting the voltage, temperature and time data recorded in the storage medium to a remote device (step 310). The voltage, temperature, and time data, together with other relevant data, may be assessed, analyzed, processed, and/or utilized as an input to various computing systems, resources, and/or applications (step 312). In this exemplary method, thevoltage sensor 130,temperature sensor 140, and storage medium are located outside thebattery 100/200 on abattery monitor circuit 120. Moreover,method 300 may comprise taking various actions in response to the voltage, temperature, and/or time data (step 314), for example charging a battery, discharging a battery, removing a battery from a warehouse, replacing a battery with a new battery, and/or the like. - With reference now to
FIG. 4A , in an exemplary embodiment, thebattery monitor circuit 120 is configured to communicate data with a remote device. The remote device may be configured to receive data from a plurality of batteries, with each battery equipped with abattery monitor circuit 120. For example, the remote device may receive data fromindividual batteries 100, each connected to abattery monitor circuit 120. And in another exemplary embodiment, the remote device may receive data fromindividual batteries 200, eachbattery 200 connected to abattery monitor circuit 120. - An
example system 400 is disclosed for collecting and using data associated with eachbattery 100/200. In general, the remote device is an electronic device that is not physically part of thebattery 100/200 or thebattery monitor circuit 120. Thesystem 400 may comprise alocal portion 410 and/or aremote portion 420. Thelocal portion 410 comprises components located relatively near the battery orbatteries 100/200. “Relatively near,” in one exemplary embodiment, means within wireless signal range of the battery monitor circuit antenna. In another example embodiment, “relatively near” means within Bluetooth range, within the same cabinet, within the same room, and the like. Thelocal portion 410 may comprise, for example, one ormore batteries 100/200, abattery monitor circuit 120, and optionally a remote device located in thelocal portion 410. Moreover, the local portion may comprise, for example, a gateway. The gateway may be configured to receive data from eachbattery 100/200. The gateway may also be configured to transmit instructions to eachbattery 100/200. In an example embodiment, the gateway comprises an antenna for transmitting/receiving wirelessly at the gateway and/or for communicating with a locally locatedremote device 414. The locally locatedremote device 414, in an exemplary embodiment, is a smartphone, tablet, or other electronic mobile device. In another exemplary embodiment, the locally locatedremote device 414 is a computer, a network, a server, or the like. In a further exemplary embodiment, the locally locatedremote device 414 is an onboard vehicle electronics system. Yet further, in some embodiments, the gateway may function as locally locatedremote device 414. Exemplary communications, for example between gateway 412 and locally locatedremote device 414, may be via any suitable wired or wireless approach, for example via a Bluetooth protocol. - In some exemplary embodiments, the remote device is not located in the
local portion 410, but is located in theremote portion 420. Theremote portion 420 may comprise any suitable back-end systems. For example, the remote device in theremote portion 420 may comprise a computer 424 (e.g., a desk-top computer, a laptop computer, a server, a mobile device, or any suitable device for using or processing the data as described herein). The remote portion may further comprise cloud-based computing and/or storage services, on-demand computing resources, or any suitable similar components. Thus, the remote device, in various exemplary embodiments, may be acomputer 424, a server, a back-end system, a desktop, a cloud system, or the like. - In an exemplary embodiment, the
battery monitor circuit 120 may be configured to communicate data directly betweenbattery monitor circuit 120 and the locally locatedremote device 414. In one embodiment, this communication can be by wire. For example, the wire communication can be by Ethernet cable, USB cable, twisted pair, and/or any other suitable wire and corresponding wired communication protocol. In another exemplary embodiment, the communication between thebattery monitor circuit 120 and the locally locatedremote device 414 can be a wireless transmission, such as via Bluetooth transmission. Moreover, any suitable wireless protocol can be used. - In an exemplary embodiment, the
battery monitor circuit 120 further comprises a cellular modem for communicating via acellular network 418 and other networks, such as the Internet, with the remote device. For example, data may be shared with thecomputer 424 or with the locally locatedremote device 414 via thecellular network 418. Thus,battery monitor circuit 120 may be configured to send temperature and voltage data to the remote device and receive communications from the remote device, via thecellular network 418 to other networks, such as the Internet, for distribution anywhere in the Internet connected world. - In various exemplary embodiments, the data from the
local portion 410 is communicated to theremote portion 420. For example, data and/or instructions from thebattery monitor circuit 120 may be communicated to a remote device in theremote portion 420. In an exemplary embodiment, the locally locatedremote device 414 may communicate data and/or instructions with thecomputer 424 in theremote portion 420. In an exemplary embodiment, these communications are sent over the Internet. The communications may be secured and/or encrypted, as desired, in order to preserve the security thereof. - In an exemplary embodiment, these communications may be sent using any suitable communication protocol, for example, via TCP/IP, WLAN, over Ethernet, WiFi, cellular radio, or the like. In one exemplary embodiment, the locally located
remote device 414 is connected through a local network by a wire to the Internet and thereby to any desired remotely located remote device. In another exemplary embodiment, the locally locatedremote device 414 is connected through a cellular network, for examplecellular network 418, to the Internet and thereby to any desired remotely located remote device. - In an exemplary embodiment, this data may be received at a server, received at a
computer 424, stored in a cloud-based storage system, on servers, in databases, or the like. In an exemplary embodiment, this data may be processed by thebattery monitor circuit 120, the locally locatedremote device 414, thecomputer 424, and/or any suitable remote device. Thus, it will be appreciated that processing and analysis described as occurring in thebattery monitor circuit 120 may also occur fully or partially in thebattery monitor circuit 120, the locally locatedremote device 414, thecomputer 424, and/or any other remote device. - The
remote portion 420 may be configured, for example, to display, process, utilize, or take action in response to, information regardingmany batteries 100/200 that are geographically dispersed from one another and/or that include a diverse or differing types, groups, and/or sets ofbatteries 100/200. Theremote portion 420 can display information about, or based on, specific individual battery temperature and/or voltage. Thus, the system can monitor a large group ofbatteries 100/200 located great distances from each other, but do so on an individual battery level. - The
remote portion 420 device may be networked such that it is accessible from anywhere in the world. Users may be issued access credentials to allow their access to only data pertinent to batteries owned or operated by them. In some embodiments, access control may be provided by assigning a serial number to the remote device and providing this number confidentially to the battery owner or operator to log into. - Voltage, temperature and time data stored in a cloud-based system may be presented in various displays to convey information about the status of a battery, its condition, its operating requirement(s), unusual or abnormal conditions, and/or the like. In one embodiment, data from one battery or group of batteries may be analyzed to provide additional information, or correlated with data from other batteries, groups of batteries, or exogenous conditions to provide additional information.
- Systems and methods disclosed herein provide an economical means for monitoring the performance and health of batteries located anywhere in the cellular radio or Internet connected world. As
battery monitor circuits 120 rely on only voltage, temperature and time data to perform (or enable performance of) these functions, cost is significantly less than various prior art systems which must monitor battery current as well. Further, performance of calculations and analyses in a remote device, which is capable of receiving voltage, temperature and time data from a plurality of monitoring circuits connected to a plurality of batteries, rather than performing these functions at each battery in the plurality of batteries, minimizes the per battery cost to monitor any one battery, analyze its performance and health, and display the results of such analyses. This allows effective monitoring of batteries, critical to various operations but heretofore not monitored because an effective remote monitoring system was unavailable and/or the cost to monitor batteries locally and collect data manually was prohibitive. Example systems allow aggregated remote monitoring of batteries in such example applications as industrial motive power (forklifts, scissor lifts, tractors, pumps and lights, etc.), low speed electric vehicles (neighborhood electric vehicles, electric golf carts, electric bikes, scooters, skateboards, etc.), grid power backup power supplies (computers, emergency lighting, and critical loads remotely located), marine applications (engine starting batteries, onboard power supplies), automotive applications, and/or other example applications (for example, engine starting batteries, over-the-road truck and recreational vehicle onboard power, and the like). This aggregated remote monitoring of like and/or disparate batteries in like and/or disparate applications allows the analysis of battery performance and health (e.g., battery state-of-charge, battery reserve time, battery operating mode, adverse thermal conditions, and so forth), that heretofore was not possible. Using contemporaneous voltage and temperature data, stored voltage and temperature data, and/or battery and application specific parameters (but excludingdata regarding battery 100/200 current), the short term changes in voltage and/or temperature, longer term changes in voltage and/or temperature, and thresholds for voltage and/or temperature may be used singularly or in combination to conduct exemplary analyses, such as in thebattery monitor circuit 120, the locally locatedremote device 414, thecomputer 424, and/or any suitable device. The results of these analyses, and actions taken in response thereto, can increase battery performance, improve battery safety and reduce battery operating costs. - While many of the embodiments herein have focused on electrochemical cell(s) which are lead-acid type electrochemical cells, in other embodiments the electrochemical cells may be of various chemistries, including but not limited to, lithium, nickel, cadmium, sodium and zinc. In such embodiments, the battery monitor circuit and/or the remote device may be configured to perform calculations and analyses pertinent to that specific battery chemistry.
- In some example embodiments, via application of principles of the present disclosure, outlier batteries can be identified and alerts or notices provided by the
battery monitor circuit 120 and/or the remote device to prompt action for maintaining and securing the batteries. Thebatteries 100/200 may be made by different manufacturers, made using different types of construction or different types of cells. However, wheremultiple batteries 100/200 are constructed in similar manner and are situated in similar environmental conditions, the system may be configured to identify outlier batteries, for example batteries that are returning different and/or suspect temperature and/or voltage data. This outlier data may be used to identify failing batteries or to identify local conditions (high load, or the like) and to provide alerts or notices for maintaining and securing such batteries. Similarly,batteries 100/200 in disparate applications or from disparate manufacturers can be compared to determine which battery types and/or manufacturers products perform best in any particular application. - In an exemplary embodiment, the
battery monitor circuit 120 and/or the remote device may be configured to analyze the data and take actions, send notifications, and make determinations based on the data. Thebattery monitor circuit 120 and/or the remote device may be configured to show a present temperature for eachbattery 100/200 and/or a present voltage for eachbattery 100/200. Moreover, this information can be shown with the individual measurements grouped by temperature or voltage ranges, for example for prompting maintenance and safety actions by providing notification of batteries that are outside of a pre-determined range(s) or close to being outside of such range. - Moreover, the
battery monitor circuit 120 and/or the remote device can display the physical location of eachbattery 100/200 (as determined by the battery monitor circuit 120) for providing inventory management of the batteries or for securing the batteries. In one exemplary embodiment, the physical location information is determined by thebattery monitor circuit 120 using a cellular network. Alternatively, this information can be provided by the Global Positioning System (GPS) via a GPS receiver installed in thebattery monitor circuit 120. This location information can be stored with the voltage, temperature, and time data. In another exemplary embodiment, the location data is shared wirelessly with the remote device, and the remote device is configured to store the location data. The location data may be stored in conjunction with the time, to create a travel history (location history) for the monobloc that reflects where the monobloc or battery has been over time. - Moreover, the remote device can be configured to create and/or send notifications based on the data. For example, a notification can be displayed if, based on analysis in the battery monitor circuit and/or the remote device a specific monobloc is over voltage, the notification can identify the specific monobloc that is over voltage, and the system can prompt maintenance action. Notifications may be sent via any suitable system or means, for example via e-mail, SMS message, telephone call, in-application prompt, or the like.
- In an exemplary embodiment, where the
battery monitor circuit 120 has been connected to abattery 100/200, the system provides inventory and maintenance services for thebattery 100/200. For example, the system may be configured to detect the presence of a monobloc or battery in storage or transit, without touching the monobloc or battery. Thebattery monitor circuit 120 can be configured, in an exemplary embodiment, for inventory tracking in a warehouse. In one exemplary embodiment, thebattery monitor circuit 120 transmits location data to the locally locatedremote device 414 and/or a remotely located remote device and back-end system configured to identify when aspecific battery 100/200 has left the warehouse or truck, for example unexpectedly. This may be detected, for example, whenbattery monitor circuit 120 associated with thebattery 100/200 ceases to communicate voltage and/or temperature data with the locally locatedremote device 414 and/or back end system, when the battery location is no longer where noted in a location database, or when the wired connection between the monobloc or battery and thebattery monitor circuit 120 is otherwise severed. The remote back end system is configured, in an exemplary embodiment, to trigger an alert that a battery may have been stolen. The remote back end system may be configured to trigger an alert that a battery is in the process of being stolen, for example as successive monoblocs in a battery stop (or lose) communication or stop reporting voltage and temperature information. In an exemplary embodiment, wherein thebattery monitor circuit 120 is configured with Bluetooth communications and connected by wire to a battery, thebattery monitor circuit 120 may be configured to identify if thebattery 100/200 leaves a warehouse unexpectedly and, in that event, to send an alarm, alert, or notification. In another embodiment wherein thebattery monitor circuit 120 communicates via a cellular network with a remote device, the actual location of the battery can be tracked and a notification generated if the battery travels outside a predefined geo-fenced area. These various embodiments of theft detection and inventory tracking are unique as compared to prior approaches, for example, because they can occur at greater distance than RFID type querying of individual objects, and thus can reflect the presence of objects that are not readily observable (e.g., inventory stacked in multiple layers on shelves or pallets) where RFID would not be able to provide similar functionality. - In some exemplary embodiments, the remote device (e.g., the locally located remote device 414) is configured to remotely receive data regarding the voltage and temperature of each
battery 100/200. In an exemplary embodiment, the remote device is configured to remotely receive voltage, temperature, and time data from eachbattery monitor circuit 120 associated with eachbattery 100/200 of a plurality of batteries. These batteries may, for example, be inactive or non-operational. For example, these batteries may not yet have been installed in an application, connected to a load, or put in service. The system may be configured to determine which batteries need re-charging. These batteries may or may not be contained in shipping packaging. However, because the data is received and the determination is made remotely, the packaged batteries do not need to be unpackaged to receive this data or make the determination. So long as abattery monitor circuit 120 has been attached to these batteries, these batteries may be located in a warehouse, in a storage facility, on a shelf, or on a pallet, but the data can be received and the determination made without unpacking, unstacking, touching or moving any of the plurality of batteries. These batteries may even be in transit, such as on a truck or in a shipping container, and the data can be received and the determination made during such transit. Thereafter, at an appropriate time, for example upon unpacking a pallet, the battery or batteries needing re-charging may be identified and charged. - In a further exemplary embodiment, the process of “checking” a battery may be described herein as receiving voltage data and temperature data (and potentially, time data) associated with a battery, and presenting information to a user based on this data, wherein the information presented is useful for making a determination or assessment about the battery. In an exemplary embodiment, the remote device is configured to remotely “check” each
battery 100/200 of a plurality of batteries equipped withbattery monitor circuit 120. In this exemplary embodiment, the remote device can receive wireless signals from each of the plurality ofbatteries 100/200, and check the voltage and temperature of eachbattery 100/200. Thus, in these exemplary embodiments, the remote device can be used to quickly interrogate a pallet of batteries that are awaiting shipment to determine if any battery needs to be re-charged, how long until a particular battery will need to be re-charged, or if any state of health issues are apparent in a particular battery, all without un-packaging or otherwise touching the pallet of batteries. This checking can be performed, for example, without scanning, pinging, moving or individually interrogating the packaging or batteries, but rather based on thebattery monitor circuit 120 associated with eachbattery 100/200 wirelessly reporting the data to the remote device (e.g., 414/424). - In an exemplary embodiment, the
battery 100/200 is configured to identify itself electronically. For example, thebattery 100/200 may be configured to communicate a unique electronic identifier (unique serial number, or the like) from thebattery monitor circuit 120 to the remote device, thecellular network 418, or the locally locatedremote device 414. This serial number may be correlated with a visible battery identifier (e.g., label, barcode, QR code, serial number, or the like) visible on the outside of the battery, or electronically visible by means of a reader capable of identifying a single battery in a group of batteries. Therefore, thesystem 400 may be configured to associate battery data from a specific battery with a unique identifier of that specific battery. Moreover, during installation of a monobloc with abattery monitor circuit 120 attached (for example, battery 100) in abattery 200, an installer may enter into a database associated withsystem 400 various information about the monobloc, for example relative position (e.g., what battery, what string, what position on a shelf, the orientation of a cabinet, etc.). Similar information may be entered into a database regarding abattery 100. - Thus, if the data indicates a battery of interest (for example, one that is performing subpar, overheating, discharged, etc.), that particular battery can be singled out for any appropriate action. Stated another way, a user can receive information about a specific battery (identified by the unique electronic identifier), and go directly to that battery (identified by the visible battery identifier) to attend to any needs it may have (perform “maintenance”). For example, this maintenance may include removing the identified battery from service, repairing the identified battery, charging the identified battery, etc. In a specific exemplary embodiment, a
battery 100/200 may be noted as needing to be re-charged, a warehouse employee could scan the batteries on the shelves in the warehouse (e.g., scanning a QR code on eachbattery 100/200) to find the battery of interest and then recharge it. In another exemplary embodiment, as the batteries are moved to be shipped, and the package containing the battery moves along a conveyor, past a reader, the locally locatedremote device 414 can be configured to retrieve the data on that specific battery, including the unique electronic identifier, voltage and temperature, and alert if some action needs to be taken with respect to it (e.g., if the battery needs to be recharged before shipment). - In an exemplary embodiment, the
battery monitor circuit 120 itself, the remote device and/or any suitable storage device can be configured to store the battery operation history of theindividual battery 100/200 through more than one phase of the battery's life. In an exemplary embodiment, the history of the battery can be recorded. In an exemplary embodiment, the battery may further record data after it is integrated into a product or placed in service (alone or in a battery). The battery may record data after it is retired, reused in a second life application, and/or until it is eventually recycled or disposed. - Although sometimes described herein as storing this data on the
battery monitor circuit 120, in a specific exemplary embodiment, the historical data is stored remotely from thebattery monitor circuit 120. For example, the data described herein can be stored in one or more databases remote from the battery monitor circuit 120 (e.g., in a cloud-based storage offering, at a back-end server, at the gateway, and/or on one or more remote devices). - The
system 400 may be configured to store, during one or more of the aforementioned time periods, the history of how the battery has been operated, the environmental conditions in which it has been operated, and/or the society it has kept with other batteries, as may be determined based on the data stored during these time periods. For example, the remote device may be configured to store the identity of other batteries that were electrically associated with thebattery 100/200, such as if two batteries are used together in one application. This shared society information may be based on the above described unique electronic identifier and data identifying where (geographically) the battery is located. The remote device may further store when the batteries shared in a particular operation. - This historical information, and the analyses that are performed using it, can be based solely on the voltage, temperature and time data. Stated another way, current data is not utilized. As used herein, “time” may include the date, hour, minute, and/or second of a voltage/temperature measurement. In another exemplary embodiment, “time” may mean the amount of time that the voltage/temperature condition existed. In particular, the history is not based on data derived from the charge and discharge currents associated with the battery(s). This is particularly significant because it would be very prohibitive to connect to and include a sensor to measure the current for each and every monobloc, and an associated time each was sensed from the individual battery, where there is a large number of monoblocs.
- In various exemplary embodiments, system 400 (and/or components thereof) may be in communication with an external battery management system (BMS) coupled one or
more batteries 100/200, for example over a common network such as the Internet.System 400 may communicate information regarding one ormore batteries 100/200 to the BMS and the BMS may take action in response thereto, for example by controlling or modifying current into and/or out of one ormore batteries 100/200, in order to protectbatteries 100/200. - In an exemplary embodiment, in contrast to past solutions, the system is configured to store contemporaneous voltage and/or contemporaneous temperature data relative to geographically dispersed batteries. This is a significant improvement over past solutions where there is no contemporaneous voltage and/or contemporaneous temperature data available on multiple monoblocs or batteries located in different locations and operating in different conditions. Thus, in the exemplary embodiment, historical voltage and temperature data is used to assess the condition of the monoblocs or batteries and/or make predictions about and comparisons of the future condition of the monobloc or battery.
- In an exemplary embodiment, the
battery monitor circuit 120 is located such that it is viewable/accessible from the outside ofbattery 100/200. In another example,battery monitor circuit 120 is located external to thebattery 100/200 in a location that will measure the external temperature of thebattery 100/200. For example, thebattery monitor circuit 120 may measure the temperature in between two or more monoblocs, the outer casing temperature of a monobloc, or the air temperature in a battery containing multiple monoblocs. - With reference now to
FIG. 4C , in various exemplary embodiments abattery 100/200 having abattery monitor circuit 120 coupled thereto may be coupled to a load and/or to a power supply. For example,battery 100/200 may be coupled to a vehicle to provide electrical energy for motive power. Additionally and/or alternatively,battery 100/200 may be coupled to a solar panel to provide a charging current forbattery 100/200. Moreover, invarious applications battery 100/200 may be coupled to an electrical grid. It will be appreciated that the nature and number of systems and/or components to whichbattery 100/200 is coupled may impact desired approaches for monitoring ofbattery 100/200, for example via application of various methods, algorithms, and/or techniques as described herein. Yet further, in various applications and methods disclosed herein,battery 100/200 is not coupled to any external load or a charging source, but is disconnected (for example, when sitting in storage in a warehouse). - For example, various systems and methods may utilize information specific to the characteristics of
battery 100/200 and/or the specific application in whichbattery 100/200 is operating. For example,battery 100/200 and application specific characteristics may include the manufacture date, the battery capacity, and recommended operating parameters such as voltage and temperature limits. In an example embodiment, battery and application specific characteristics may be the chemistry ofbattery 100/200—e.g., absorptive glass mat lead acid, gelled electrolyte lead acid, flooded lead acid, lithium manganese oxide, lithium cobalt oxide, lithium iron phosphate, lithium nickel manganese cobalt, lithium cobalt aluminum, nickel zinc, zinc air, nickel metal hydride, nickel cadmium, and/or the like. - In an example embodiment, battery specific characteristics may be the battery manufacturer, model number, battery capacity in ampere-hours (Ah), nominal voltage, float voltage, state of charge v. open circuit voltage, state of charge, voltage on load, and/or equalized voltage, and so forth. Moreover, the characteristics can be any suitable specific characteristic of
battery 100/200. - In various exemplary embodiments, application specific characteristics may identify the application as a cellular radio base station, an electric forklift, an e-bike, and/or the like. More generally, application specific characteristics may distinguish between grid-coupled applications and mobile applications.
- In various example embodiments,
information characterizing battery 100/200 can be input by: manually typing the information: into a software program running on a mobile device, into a web interface presented by a server to a computer or mobile device, or any other suitable manual data entry method. In other example embodiments,information characterizing battery 100/200 can be selected from a menu or checklist (e.g., selecting the supplier or model of a battery from a menu). In other example embodiments, information can be received by scanning a QR code on the battery. In other example embodiments,information characterizing battery 100/200 can be stored in one or more databases (e.g., by the users providing an identifier that links to a database storing this information). For example, databases such as Department of Motor Vehicles, battery manufacturer and OEM databases, fleet databases, and other suitable databases may have parameters and other information useful for characterizing the application of a battery orbatteries 100/200. Moreover, the characteristics can be any suitable application specific characteristic. - In one example embodiment, if
battery 100/200 is coupled tobattery monitor circuit 120, battery and application specific characteristics can be programmed onto the circuitry (e.g., in a battery parameters table). In this case, these characteristics for eachbattery 100/200 travel withbattery 100/200 and can be accessed by any suitable system performing the analysis described herein. In another example embodiment, the battery and application specific characteristics can be stored remote frombattery 100/200, for example in the remote device. Moreover, any suitable method for receivinginformation characterizing battery 100/200 may be used. In an example embodiment, the information can be stored on a mobile device, on a data collection device (e.g., a gateway), or in the cloud. Moreover, exemplary systems and methods may be further configured to receive, store, and utilize specific characteristics related to a battery charger (e.g., charger manufacturer, model, current output, charge algorithm, and/or the like). - The various system components discussed herein may include one or more of the following: a host server or other computing systems including a processor for processing digital data; a memory coupled to the processor for storing digital data; an input digitizer coupled to the processor for inputting digital data; an application program stored in the memory and accessible by the processor for directing processing of digital data by the processor; a display device coupled to the processor and memory for displaying information derived from digital data processed by the processor; and a plurality of databases.

Examples of communications interface may include a modem, a network interface (such as an Ethernet card), a communications port, a Personal Computer Memory Card International Association (PCMCIA) slot and card, etc. Software and data transferred via communications interface are in the form of signals which may be electronic, electromagnetic, optical or other signals capable of being received by a communications interface. These signals are provided to communications interface via a communications path (e.g., channel). This channel carries signals and may be implemented using wire, cable, fiber optics, a telephone line, a cellular link, a radio frequency (RF) link, wireless and other communications channels.

The various system components may be independently, separately or collectively suitably coupled to the network via data links. - “Cloud” or “cloud computing” includes a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. Cloud computing may include location-independent computing, whereby shared servers provide resources, software, and data to computers and other devices on demand. For more information regarding cloud computing, see the NIST's (National Institute of Standards and Technology) definition of cloud computing available at https://doi.org/10.66028/NIST.SP.800-145 (last visited July 2018), which is hereby incorporated by reference in its entirety.
- As used herein, “transmit” may include sending electronic data from one system component to another over a network connection. Additionally, as used herein, “data” may include encompassing information such as commands, queries, files, data for storage, and the like in digital or any other form.
- The system contemplates uses in association with web services, utility computing, pervasive and individualized computing, security and identity solutions, autonomic computing, cloud computing, commodity computing, mobility and wireless solutions, open source, biometrics, grid computing and/or mesh computing.
- Any databases discussed herein may include relational, hierarchical, graphical, blockchain, object-oriented structure and/or any other database configurations. Common database products that may be used to implement the databases include DB2 by IBM® (Armonk, N.Y.), various database products available from ORACLE® Corporation (Redwood Shores, Calif.), MICROSOFT® Access® or MICROSOFT® SQL Server® by MICROSOFT® Corporation (Redmond, Wash.), MySQL by MySQL AB (Uppsala, Sweden), MongoDB®, Redis®, Apache Cassandra®, HBase by APACHE®, MapR-DB, or any other suitable database product. Moreover, the databases may be organized in any suitable manner, for example, as data tables or lookup tables. Each record may be a single file, a series of files, a linked series of data fields or any other data structure.
- Any database discussed herein may comprise a distributed ledger maintained by a plurality of computing devices (e.g., nodes) over a peer-to-peer network. Each computing device maintains a copy and/or partial copy of the distributed ledger and communicates with one or more other computing devices in the network to validate and write data to the distributed ledger. The distributed ledger may use features and functionality of blockchain technology, including, for example, consensus based validation, immutability, and cryptographically chained blocks of data. The blockchain may comprise a ledger of interconnected blocks containing data. The blockchain may provide enhanced security because each block may hold individual transactions and the results of any blockchain executables. Each block may link to the previous block and may include a timestamp. Blocks may be linked because each block may include the hash of the prior block in the blockchain. The linked blocks form a chain, with only one successor block allowed to link to one other predecessor block for a single chain. Forks may be possible where divergent chains are established from a previously uniform blockchain, though typically only one of the divergent chains will be maintained as the consensus chain. In various embodiments, the blockchain may implement smart contracts that enforce data workflows in a decentralized manner. The system may also include applications deployed on user devices such as, for example, computers, tablets, smartphones, Internet of Things devices (“IoT” devices), etc. The applications may communicate with the blockchain (e.g., directly or via a blockchain node) to transmit and retrieve data. In various embodiments, a governing organization or consortium may control access to data stored on the blockchain. Registration with the managing organization(s) may enable participation in the blockchain network.
- Data transfers performed through the blockchain-based system may propagate to the connected peers within the blockchain network within a duration that may be determined by the block creation time of the specific blockchain technology implemented. The system also offers increased security at least partially due to the relative immutable nature of data that is stored in the blockchain, reducing the probability of tampering with various data inputs and outputs. Moreover, the system may also offer increased security of data by performing cryptographic processes on the data prior to storing the data on the blockchain. Therefore, by transmitting, storing, and accessing data using the system described herein, the security of the data is improved, which decreases the risk of the computer or network from being compromised.
- In various embodiments, the system may also reduce database synchronization errors by providing a common data structure, thus at least partially improving the integrity of stored data. The system also offers increased reliability and fault tolerance over traditional databases (e.g., relational databases, distributed databases, etc.) as each node operates with a full copy of the stored data, thus at least partially reducing downtime due to localized network outages and hardware failures. The system may also increase the reliability of data transfers in a network environment having reliable and unreliable peers, as each node broadcasts messages to all connected peers, and, as each block comprises a link to a previous block, a node may quickly detect a missing block and propagate a request for the missing block to the other nodes in the blockchain network.

The system further comprises the remote device for receiving the output data from each of the plurality of batteries, wherein the remote device utilizes the voltage data and the temperature data to make at least one determination, based only on the voltage data and the temperature data, about the operation of the battery.
- The remote device may be configured to receive the output data from the plurality of batteries and record a location of each of the plurality of batteries, and the output data of each of the plurality of batteries; wherein the remote device is configured to display a location, voltage, and temperature history for one or more of the plurality of batteries and provide notifications, via local displays, SMS text, e-mail, cellular calls or other remote communications means, that an abnormal condition exists with the battery or its operation. At least one of the processor and the remote device may be configured for assessing/predicting a battery condition based on historical output data, gathered under real time operating conditions, over time, while the battery is in operation, wherein the system does not comprise a testing apparatus, does not apply an artificial load, and does not use current to make the assessment/prediction. The at least one determination may comprise a determination of at least one of the following: Operating mode, Battery health, State of charge, Time to recharge, Remaining life, Operating time, Discharge duration, Discharge depth, Battery performance, Battery theft, Battery stress, Battery warranty, Battery abuse, Battery Location, or Alerts (Charge required, Over discharge, Under charge, Over charge, Under temperature, Over Temperature). Moreover, the at least one determination may comprise a determination of at least one of the following: Operating mode, Battery health, State of charge, Time to recharge, Remaining life, Operating time, Discharge duration, Discharge depth, Battery performance, Battery theft, Battery stress, Battery warranty, Battery abuse, Battery Location, Alerts (Charge required, Over discharge, Under charge, Over charge, Under temperature, Over Temperature) in the remote device comprising a cloud connected server displaying the results of such determinations in a manner that such results and the output data from which they are derived are available over the Internet for viewing and downloading anywhere in the connected world.
- In describing the present disclosure, the following terminology will be used: The singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to an item includes reference to one or more items. The term “ones” refers to one, two, or more, and generally applies to the selection of some or all of a quantity. The term “plurality” refers to two or more of an item. The term “about” means quantities, dimensions, sizes, formulations, parameters, shapes and other characteristics need not be exact, but may be approximated and/or larger or smaller, as desired, reflecting acceptable tolerances, conversion factors, rounding off, measurement error and the like and other factors known to those of skill in the art. The term “substantially” means that the recited characteristic, parameter, or value need not be achieved exactly, but that deviations or variations, including for example, tolerances, measurement error, measurement accuracy limitations and other factors known to those of skill in the art, may occur in amounts that do not preclude the effect the characteristic was intended to provide. Numerical data may be expressed or presented herein in a range format. It is to be understood that such a range format is used merely for convenience and brevity and thus should be interpreted flexibly to include not only the numerical values explicitly recited as the limits of the range, but also interpreted to include all of the individual numerical values or sub-ranges encompassed within that range as if each numerical value and sub-range is explicitly recited. As an illustration, a numerical range of “about 1 to 5” should be interpreted to include not only the explicitly recited values of about 1 to about 5, but also include individual values and sub-ranges within the indicated range. Thus, included in this numerical range are individual values such as 2, 3 and 4 and sub-ranges such as 1-3, 2-4 and 3-5, etc. This same principle applies to ranges reciting only one numerical value (e.g., “greater than about 1”) and should apply regardless of the breadth of the range or the characteristics being described. A plurality of items may be presented in a common list for convenience. However, these lists should be construed as though each member of the list is individually identified as a separate and unique member. Thus, no individual member of such list should be construed as a de facto equivalent of any other member of the same list solely based on their presentation in a common group without indications to the contrary. Furthermore, where the terms “and” and “or” are used in conjunction with a list of items, they are to be interpreted broadly, in that any one or more of the listed items may be used alone or in combination with other listed items. The term “alternatively” refers to selection of one of two or more alternatives, and is not intended to limit the selection to only those listed alternatives or to only one of the listed alternatives at a time, unless the context clearly indicates otherwise.
- It should be appreciated that the particular implementations shown and described herein are illustrative and are not intended to otherwise limit the scope of the present disclosure in any way. Furthermore, the connecting lines shown in the various figures contained herein are intended to represent exemplary functional relationships and/or physical couplings between the various elements. It should be noted that many alternative or additional functional relationships or physical connections may be present in a practical device or system.
- It should be understood, however, that the detailed description and specific examples, while indicating exemplary embodiments, are given for purposes of illustration only and not of limitation. Many changes and modifications within the scope of the present disclosure may be made without departing from the spirit thereof, and the scope of this disclosure includes all such modifications. The corresponding structures, materials, acts, and equivalents of all elements in the claims below are intended to include any structure, material, or acts for performing the functions in combination with other claimed elements as specifically claimed. The scope should be determined by the appended claims and their legal equivalents, rather than by the examples given above. For example, the operations recited in any method claims may be executed in any order and are not limited to the order presented in the claims. Moreover, no element is essential unless specifically described herein as “critical” or “essential.”
- Moreover, where a phrase similar to ‘at least one of A, B, and C’ or ‘at least one of A, B, or C’ is used in the claims or specification, it is intended that the phrase be interpreted to mean that A alone may be present in an embodiment, B alone may be present in an embodiment, C alone may be present in an embodiment, or that any combination of the elements A, B and C may be present in a single embodiment; for example, A and B, A and C, B and C, or A and B and C.
