Fig. 2 shows a first embodiment of the battery record management system according to the present invention. The battery record management system 14 of the present invention includes at least one battery management device 16 and a cloud server 18. The number of battery management devices 16 is exemplified here by one. The battery management device 16 includes a storage device 20, a battery control unit 22 and a Global Positioning System (GPS) module 24. The battery control unit 22 is electrically connected to the storage device 20, the global positioning system 24, at least one battery 26, and a wireless module 28, wherein the wireless module 28 is, for example, a 2G module, a 3G module, or a GPRS module. The battery control unit 22 is provided with a control program, and accordingly retrieves the history information of the battery 26 to record it in the storage device 20. The number of cells 26 is exemplified here by one. The cloud server 18 is wirelessly connected to the battery control unit 22 through the wireless module 28, and provides at least one management request (request), and may also provide multiple management requests simultaneously or sequentially. The battery control unit 22 uploads the history information to the cloud server 18 via the wireless module 28. Then, the battery control unit 22 reads the management request through the wireless module 28 to manage the battery 26 or the storage device 20 accordingly. The global positioning satellite module 24 locates itself to establish a position data. In order to avoid that the battery control unit 22 uploads the history information to the cloud server 18 through the wireless module 28 for too long time and fails to take into account other programs that the battery control unit 22 must continuously execute, such as the history information of the battery 26 in the next time period that the battery control unit 22 intends to upload the history information to the cloud server 18, the time period that the battery control unit 22 uploads the history information to the cloud server 18 through the wireless module 28 is limited to a preset time period, for example, 0.01 to 1 second each time, and once the preset time period is exceeded and the history information is not uploaded, the battery control unit 22 uploads the history information that is not uploaded to the cloud server 18 through the wireless module 28 when the battery control unit 22 is connected with the cloud server 18 through the wireless module 28 next time. The present invention automatically stores the historical information of the battery 26, and also can synchronously update the physical state record and the abnormal record of the battery 26 to the cloud server 18 periodically or aperiodically, so as to facilitate maintenance analysis, and further reduce the maintenance cost and the maintenance schedule. In addition, customer service needs may be passively provided, even with customer care services being actively initiated based on information in cloud server 18. The present invention is directed to the management request, and is not actively instructed by the cloud server 18 to the battery control unit 22, which may disturb the operation of the battery control unit 22. On the contrary, the present invention only provides the management request in the cloud server 18, and downloads and reads the battery data after the battery control unit 22 uploads the battery data, so as to schedule time by using the management request, and perform special application on the battery 26 or the storage device 20, so as to reduce the interference of program interruption to the battery control unit 22, and also reduce the program processing load of the battery control unit 22.
The historical information also includes history information, a plurality of first interaction information and real-time information of the battery 26. The history information includes the factory time, test record, first use time, charging times, cycle life and abnormal occurrence time of the battery 26; each first interaction message includes a state of the battery 26 and a corresponding occurrence time stamp, a state duration and first physical parameters, the state is a charging state, a discharging state, a standby state, a protection state, a sleep state or a shutdown state, and the first physical parameters further include position data, power, current, voltage, temperature and residual capacity of the battery 26 when the occurrence time stamp occurs; the real-time information includes position data, power, current, voltage, temperature, and remaining capacity of the battery 26. While the battery 26 is being charged or discharged, the battery control unit 22 monitors the voltage, temperature and current of the battery 26 at any time. The state of the battery 26 is determined according to its own physical parameters, for example, when the current of the battery 26 is greater than +0.1 ampere, it is regarded as a charging state; a discharged state when the current of the battery 26 is less than-0.1 ampere; the battery control unit 22 presets a normal voltage, current and temperature range, and when any physical quantity exceeds the preset range 2, the battery control unit 22 stops charging or discharging according to the current situation, and is in a protection state; when the battery 26 is not in the protection state and the current is +0.1 to-0.1 ampere, the battery is regarded as the standby state; when the battery 26 stays in the standby state for 10 minutes continuously, the battery control unit 22 stops the loop of the external current and enters the sleep state, so as to reduce the internal power consumption until the battery 26 is externally connected to a charger or an electric vehicle is converted into a charging state or a discharging state; when the battery stays in the sleep state for 30 consecutive days or when the battery runs out of charge, the battery control unit 22 automatically turns off all monitoring functions, which is the power-off state.
The battery control unit 22 retrieves the first interaction information and records the first interaction information in the storage device 20, and the first interaction information occupies a small memory space in the storage device 20, and is not required to be uploaded frequently, and is uploaded to the cloud server 18 once in about several months. In addition, the battery control unit 22 sets a first sequence number for each first interaction information recorded in the storage device 20, where the first sequence number is a natural number, the recording time of the first interaction information along with the first sequence number is higher as the recording time is later, and the difference between the first sequence numbers of two adjacent recording times is 1. The battery control unit 22 sequentially uploads each first interaction information in the storage device 20 according to the recording time, and sets a second sequence number for each first interaction information uploaded to the cloud server 18, where the second sequence number is higher as the uploading time of the corresponding first interaction information is later, the second sequence number is also a natural number, and the difference between the second sequence numbers of two adjacent uploading times is 1. When the storage device 20 and the cloud server 18 both store the first interaction information and the battery control unit 22 finds that the last first sequence number is greater than the last second sequence number, the last first interaction information is uploaded to the cloud server 18 through the wireless module 28. For example, if the storage device 20 stores three first interaction information a1, B1, and C1, the corresponding first sequence numbers are 1, 2, and 3, respectively, and at this time, if the cloud server 18 only stores two first interaction information a1 and B1, the corresponding second sequence numbers are 1 and 2, respectively. In other words, the battery control unit 22 finds that the last first serial number is 3, which is greater than the last second serial number of 2, and therefore, the battery control unit 22 uploads the last first interaction information C1 to the cloud server 18 through the wireless module 28.
The battery control unit 22 updates the real-time information in the storage device 20 at regular time, and the cloud server 18 updates the real-time information when the battery control unit 22 uploads the latest real-time information in the storage device 20 to the cloud server 18 through the wireless module 28.
In the first embodiment of the present invention, if the wireless module 28 is integrated in the battery control unit 22, the battery management apparatus 16 can be connected to the cloud server 18 through the wireless module 28 anytime and anywhere. The consumer can obtain the history information and the current situation of the battery 26, the first interaction information, the prompting suggestion of the maintenance secretary, the active exception notification such as improper use, failure or theft, and the real-time troubleshooting service from the cloud server 18 anytime and anywhere, and can also track the position of the battery 26 from the cloud server 18 anytime and anywhere or forcibly stop the power supply of the battery 26.
The following describes the operation of the first embodiment of the battery record management system according to the present invention. Firstly, the battery 26 starts to work, the battery control unit 22 continuously monitors the first interaction information of the battery 26 according to a predetermined program, and periodically updates a set of real-time information of the battery 26 in the storage device 20 once per second at a preset frequency; when the state of the battery 26 changes, the battery control unit 22 regards as the occurrence of an event, and records an occurrence timestamp, a state duration timestamp, and a first physical parameter of the battery 26 at that time in an interactive information block on the storage device 20 in real time. In addition, the battery control unit 22 also checks the online status of the wireless module 28 and the cloud server 18 at the same frequency, when the wireless module 28 can be online to the cloud server 18, the battery control unit 22 not only immediately uploads the real-time information of the battery 26, but also checks whether the storage device 20 has the first interaction information that is not uploaded, and if the first interaction information that is not uploaded exists, the first interaction information is also synchronously backed up to the cloud server 18 after the real-time information. After the battery control unit 22 completes uploading the real-time information and synchronizing the first interactive information, the battery control unit 22 further checks whether there is an unprocessed management request from the cloud server 18, and downloads information of the unprocessed management request, so as to manage the battery 26 or the storage device 20 accordingly.
In this embodiment, the battery manager may set three management requests from the cloud server 18, which are respectively described as follows: the first is battery management parameter modification, which provides the most appropriate battery management parameters for personalized customization according to the use habits of consumers after the product is shipped, for example, the maximum charge capacity and the discharge reserve capacity can be adjusted according to the requirements of customers, so as to obtain the best battery service life. The second type of management request is to start a special recording mode of the battery control unit 22; the third type of management request is a firmware version upgrade of the battery control unit 22. These three types of management requests are changes or data collections set by the battery manufacturer or its authorized service operator from the cloud server 18 based on the needs or consent of the consumer. The battery control unit 22, after completing the download of the management request content, schedules an appropriate time for executing the management request according to the usage situation of the battery 26 at that time.
Fig. 3 shows a second embodiment of the battery record management system according to the present invention. The second embodiment differs from the first embodiment in the wireless module 28. In the second embodiment, the wireless module 28 further includes a short-range wireless communication interface 30 and a smart communication device 32, wherein the smart communication device 32 is a smart phone or a tablet computer, and the short-range wireless communication interface 30 is a bluetooth interface, a wireless fidelity (Wifi) interface or a Zigbee wireless protocol interface. The short-range wireless communication interface 30 is electrically connected to the battery control unit 22, the smart communication device 32 is wirelessly connected to the short-range wireless communication interface 30, and the cloud server 18 is sequentially wirelessly connected to the battery control unit 22 through the short-range wireless communication interface 30 and the smart communication device 32. The battery control unit 22 uploads the history information to the cloud server 18 through the short-range wireless communication interface 30 and the smart communication device 32, and the battery control unit 22 reads the management request through the short-range wireless communication interface 30 and the smart communication device 32.
In the second embodiment of the present invention, if the battery control unit 22 is externally connected to the short-range wireless communication interface 30 and the smart communication device 32, it means that the battery control unit 22 cannot be connected to the cloud server 18 at any time and any place. At this time, if the consumer wants to connect the short-range wireless communication interface 30 and the smart communication device 32, the consumer can go to a dealer or a maintenance station, or buy the consumer, the history information and the current status of the battery 26 can be obtained from the cloud server 18. In addition, if the short-range wireless communication interface 30 is integrated into the battery control unit 22 and the short-range wireless communication interface 30 is externally connected to the intelligent communication device 32, it also means that the battery control unit 22 cannot be connected to the cloud server 18 at any time and any place. Only when the consumer has the intelligent communication device 32, the cloud server 18 can be connected to obtain the first interaction information, the prompt suggestion of the maintenance secretary, the active exception notification such as improper use or failure, and the real-time troubleshooting service.
The operation of the second embodiment of the battery record management system provided by the present invention is described below. Firstly, the battery 26 starts to work, the battery control unit 22 continuously monitors the first interaction information of the battery 26 according to a predetermined program, and periodically updates a set of real-time information of the battery 26 in the storage device 20 once per second at a preset frequency; when the state of the battery 26 changes, the battery control unit 22 regards as the occurrence of an event, and records a final time point of the occurrence of the event and a first physical parameter of the battery 26 at that time in an interactive information block on the storage device 20 in real time. In addition, the battery control unit 22 also checks the connection status of the short-range wireless communication interface 30, the smart communication device 32 and the cloud server 18 at the same frequency, when the short-range wireless communication interface 30 and the smart communication device 32 can be connected to the cloud server 18, the battery control unit 22 not only immediately uploads the real-time information of the battery 26, but also checks whether the storage device 20 has the first interaction information that is not uploaded, and if the first interaction information that is not uploaded exists, the first interaction information is also synchronously backed up to the cloud server 18 after the real-time information. After the battery control unit 22 completes uploading the real-time information and synchronizing the first interactive information, the battery control unit 22 further checks whether there is an unprocessed management request from the cloud server 18, and downloads information of the unprocessed management request, so as to manage the battery 26 or the storage device 20 accordingly.
The application of the management request of the present invention is described below, as shown in fig. 2 and 3. The management request is a capacity adjustment request, a time limit request, a geographical range limit request, an analysis record request, or an update request. When the management request is the electric capacity adjustment request, the battery control unit 22 adjusts the maximum charge capacity or the reserved electric capacity of the battery 26 in accordance with the electric capacity adjustment request. The maximum charging capacity is adjusted, so that a customer can select an optimal scheme between the available electric quantity and the service life, and after the customer purchases the optimal scheme, the optimal scheme is ensured and replaced appropriately. For example, the power consumption of 100% can be maintained 500 times, the power consumption of 90% can be maintained 700 times, or the power consumption of 80% can be maintained 1000 times. As for the adjustment of the setting of the reserve capacity, the remaining capacity during the deep discharge can be increased or decreased to avoid the over discharge caused by the long-time storage. When special needs exist, the setting of the reserved electric quantity can be temporarily cancelled so as to prolong the journey continuation. For example, the reserved power of 10% is preset, and can be temporarily or permanently modified to 5% according to the user's requirement, or the reserved power can be cancelled, so as to provide the maximum cruising performance of the user. However, if the user is accustomed to short-distance use, often leaving the warehouse for a long time, the reserved capacity can be set to a high value of 15% or 20%.
When the management request is a time-limited request, the battery control unit 22 limits the power supply time of the battery 26 according to the time-limited request; when the management request is a geographical range restriction request, the battery control unit 22 controls the battery 26 to supply power when the location data is within a preset range according to the geographical range restriction request, and when the location data is outside the preset range, the battery control unit 22 controls the battery 26 to stop supplying power according to the geographical range restriction request. The time-limited request and the geographic range limiting request are applicable to electric vehicle leasing owners, and the functions or the performances of the batteries of the electric vehicles are limited when the batteries exceed a certain using time or geographic space limiting range according to leasing conditions, so that more convenient management tools are provided for the owners. For example, the electric vehicle in a closed specific park or city range is rented in a limited time, the use range of the battery of the electric vehicle is limited through the comparison of the built-in satellite positioning system information, and the battery must be returned within a limited time. In addition, the geographic range restriction request is also applicable to anti-theft situations. Even if the theft is not set in advance, when the theft is known to the user of the battery or the application vehicle thereof, such as an electric vehicle, the geographic range restriction request can be set from the cloud server, so that the electric vehicle can start the theft handling mode in the shortest time. Besides finding the stolen vehicle as soon as possible, the label can also frighten the burglarproof property of 35274c, and the risk of theft is reduced by the DNA probe.
When the management request is an analysis record request, the battery control unit 22 retrieves second interaction information of the battery 26 according to the analysis record request, and records the second interaction information in the storage device 20, where each second interaction information includes a control signal and a state of the battery 26 and a plurality of occurrence time points and second physical parameters corresponding to the control signal and the state, where the second physical parameters further include position data, power, current, voltage, temperature, and residual electric quantity of the occurrence time points, and a difference between adjacent occurrence time points is one hundredth of a second to several hundred seconds. In other words, the analysis recording request can be set to continuously record the selected battery state data of special concern within a period of time, so as to analyze the abnormal behavior of the battery during the use period. The second interactive message has a higher recording frequency than the first interactive message, and occupies a larger memory space in the storage device 20, so that the second interactive message also needs to be uploaded to the cloud server 18 more frequently, and ideally, the second interactive message is continuously maintained in a networking state. In addition to retrieving the second interaction information, the battery control unit 22 may also record data stored in a specific register of the storage device 20 at a second frequency according to the analysis record request, and upload the data to the cloud server 18 for performing abnormal behavior analysis.
When the management request is an update request, the battery control unit 22 reads and downloads the update request through the wireless module 28 to update the control program with the update request, thereby improving the performance of the battery control unit 22 or correcting errors that are not corrected in time when the battery 26 is shipped. For example, as long-term test data and models of new batteries are more completely built, more accurate battery life assessment and remaining power estimation algorithm parameters can be provided. In addition to originally setting the battery record data collection at the time of factory shipment, as analysis of massive data requires, it may be necessary to change the content, format or period of data collection in the form of an update request. In addition, with the improvement of the technology, the charging and discharging management strategy is upgraded, and the benefits of improving the use convenience, prolonging the service life and the like are achieved. Particularly, for rental-type services, the power storage system is used as an operating tool to update the strategy of battery management and control at any time, and prolonging the service life is an important means for reducing the operating cost and improving the profit.
In summary, in the invention, in addition to uploading the history information of the battery to the cloud server, so as to reduce the maintenance cost and the maintenance time, the management request is provided in the cloud server, so that the battery control unit can upload the data of the battery and then actively download and read the data, and can automatically arrange the time, and the management request is used for performing special application on the battery or the storage device, so as to reduce the interference of program interruption and the program processing burden on the battery control unit.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, so that equivalent changes and modifications in the shape, structure, characteristics and spirit of the present invention, which are described in the claims, should be included in the protection scope of the present invention.
