The existing parallel upgrade method generally adopts the broadcast upgrade method, which can only upgrade all parallel BMS at the same time by sending an upgrade package at one time. It cannot meet the needs of upgrading only some energy storage batteries separately, and when all BMS systems are upgraded at the same time, a large amount of upgrade bandwidth resources are required, and there will be communication interference with each other, resulting in a large number of program upgrade failures.

[0013] See also Figure 1 , Figure 1 A schematic diagram of the system architecture of an online upgrade method for a parallel energy storage battery provided in an embodiment of this specification is shown.

[0014] like Figure 1As shown, the system architecture of the online upgrade method of the parallel energy storage battery may at least include an energy storage battery 10 to be upgraded, an online upgrade platform 20 and a network 30.

[0015] The online upgrade platform 20 can provide background services for the energy storage battery 10 to be upgraded.

[0016] The network 30 is used as a medium for providing a communication link between the energy storage battery 10 to be upgraded and the online upgrade platform 20. The network 30 may include various connection types, such as wired or wireless communication links or optical fiber cables.

[0017] In addition, it should be noted that Figure 1 What is shown is only one system provided by the present disclosure. In practical applications, other systems may also be included, for example, more energy storage batteries to be upgraded may be included.

[0018] In the embodiments of this specification, the energy storage battery 10 to be upgraded and the online upgrade platform 20 may be directly or indirectly connected via wired or wireless communication, which is not limited in this disclosure.

[0019] See next Figure 2 , Figure 2 The overall flow chart of an online upgrade method of a parallel energy storage battery provided in an embodiment of this specification is shown.

[0020] like Figure 2 As shown, the online upgrade method of the parallel energy storage battery may at least include the following steps: Step 201: Obtain upgrade message information and a target upgrade package from an online upgrade platform, and determine at least one energy storage battery to be upgraded in the upgrade message information.

[0021] In the embodiments of the present specification, in order to improve the system capacity of the energy storage battery system, multiple energy storage batteries can be connected in parallel to obtain a parallel energy storage battery system. When the parallel energy storage battery system is subsequently upgraded and maintained, since the energy storage batteries in the parallel energy storage battery system may be connected at the same time, or may be connected separately according to actual usage requirements, the actual operating programs in each single energy storage battery are different. When the parallel energy storage battery system is upgraded online, the operating programs corresponding to some energy storage batteries are the same as the upgrade programs corresponding to the target upgrade package. Therefore, there is no need to upgrade all energy storage batteries at the same time, and only the designated part of the energy storage batteries needs to be upgraded. Among them, the entire parallel energy storage battery upgrade system may include an online upgrade platform and multiple parallel connected energy storage batteries. When upgrading the designated part of the energy storage batteries, the upgrade message information and the target upgrade package can be obtained from the online upgrade platform first. Among them, the upgrade message information includes the ID of the energy storage battery to be upgraded, and the number of energy storage batteries to be upgraded can be one or more, so the ID of each energy storage battery to be upgraded in the upgrade message information can be further determined, so that the same target upgrade package can be repeatedly sent to each energy storage battery to be upgraded later. As an example, the upgrade message information is ID 0x11851, 0x11A51, and the last bit of the message is 1, which determines that only the first energy storage battery needs to be upgraded. If the message information is ID 0x11851, 0x11A51; ID 0x11852, 0x11A52, then the last bit of the message is 1 and 2, which determines that the first energy storage battery and the second energy storage battery need to be upgraded.

[0022] Step 202: Determine the upgrade order of each of the energy storage batteries to be upgraded according to the current program version of each of the energy storage batteries to be upgraded.

[0023] In the embodiments of the present specification, after determining each energy storage battery to be upgraded whose running program needs to be upgraded, in order to avoid upgrading multiple energy storage batteries to be upgraded at the same time in a short period of time, causing congestion of bandwidth resources, it is necessary to further determine the upgrade order of each energy storage battery to be upgraded, so that the subsequent upgrade process can be quickly and orderly upgraded based on the upgrade order. When determining the upgrade order of each energy storage battery to be upgraded, since the time points at which each energy storage battery to be upgraded is connected in parallel may be different, resulting in different current program versions of each energy storage battery to be upgraded, it is necessary to first determine the current program version of the energy storage battery to be upgraded, and determine the upgrade weight according to the current program version of each energy storage battery to be upgraded, and finally determine the upgrade order of each energy storage battery to be upgraded according to the upgrade weight.

[0024] As an example, the current program version of the first energy storage battery is E05, and the current program version of the second energy storage battery is E02. Since program version E05 is a multiple upgrade version of program version E02, the upgrade weight of the second energy storage battery is greater than that of the first energy storage battery. Therefore, the upgrade order is to upgrade the second energy storage battery first and then the first energy storage battery.

[0025] In one possible implementation, determining the upgrade order of each of the energy storage batteries to be upgraded according to the current program version of each of the energy storage batteries to be upgraded includes: Determine the current program version of each of the energy storage batteries to be upgraded and the upgrade program version of the target upgrade package; The current program versions are compared with the upgraded program versions respectively, and the upgrade sequence of the energy storage batteries to be upgraded is determined based on the comparison results.

[0026] In the embodiment of the present specification, the current program version of each energy storage battery to be upgraded and the upgrade program version of the target upgrade package can be determined first. As an example, the current program version of the first energy storage battery is E05, the current program version of the second energy storage battery is E02, and the program version of the target upgrade package is E06. Then, each current program version is compared with the upgrade program version respectively. The comparison result of the first energy storage battery is 1 version lower than the upgrade program version, and the comparison result of the second energy storage battery is 4 versions lower than the upgrade program version. Then, the upgrade order of each energy storage battery to be upgraded is further determined according to the comparison result, that is, the second energy storage battery is upgraded first and then the first energy storage battery is upgraded. Among them, when each comparison result is characterized as the same current program version of each energy storage battery to be upgraded, the upgrade can be performed according to the ID order of each energy storage battery to be upgraded.

[0027] In one possible implementation, the comparing the current program versions with the upgraded program versions respectively, and determining the upgrade order of the energy storage batteries to be upgraded based on the comparison results, includes: Calculate the difference between the version number of the upgraded program version and the version number of each current program version to obtain each difference result; The difference results are weighted and fused based on the historical upgrade time of each current program version, and the upgrade order of each energy storage battery to be upgraded is determined according to each weighted fusion result.

[0028] In the embodiment of the present specification, when there are a large number of energy storage batteries to be upgraded, there may be multiple current program versions that are the same. If the upgrade is performed in the order of the IDs of the energy storage batteries to be upgraded, the real-time requirements of the individual energy storage batteries to be upgraded cannot be met. Therefore, the version number of the upgrade program version and the version number of each current program version can be respectively calculated to obtain the difference results. As an example, when the current program version of the first energy storage battery is E05, the current program version of the second energy storage battery is E02, the current program version of the third energy storage battery is E05, the current program version of the fourth energy storage battery is E03, and the current program version of the fifth energy storage battery is E02, and the program version of the target upgrade package is E06, the difference results are respectively the first energy storage battery D1=1, the second energy storage battery D2=4, the third energy storage battery D3=1, the fourth energy storage battery D4=3, and the fifth energy storage battery D5=4. Next, determine the historical upgrade time of the current program version in each energy storage battery to be upgraded. The earlier the historical upgrade time, the greater the corresponding upgrade weight. Therefore, the upgrade weight corresponding to each historical upgrade time can be determined according to the preset upgrade time weight rule. As an example, the upgrade time of the first energy storage battery is T1, the upgrade time of the second energy storage battery is T2, the upgrade time of the third energy storage battery is T3, the upgrade time of the fourth energy storage battery is T4, and the upgrade time of the fifth energy storage battery is T5. It is judged that each historical upgrade time T1<T2<T3<T4<T5, then the upgrade weight corresponding to each energy storage battery is the first energy storage battery upgrade time weight Q1=5, the second energy storage battery upgrade time weight Q2=4, the third energy storage battery upgrade time weight Q3=3, the fourth energy storage battery upgrade time weight Q4=2, and the fifth energy storage battery upgrade time weight Q5=1. Finally, the upgrade time weight fusion is performed on the difference results to obtain the weight fusion results H1= D1* Q1=1*5=5, H2= D2* Q2=4*4=16, H3= D3* Q3=1*3=3, H4= D4* Q4=3*2=6, H5= D5* Q5=4*1=4. Since H3<H5

[0029] Step 203: Send the target upgrade package to each of the energy storage batteries to be upgraded based on the upgrade sequence, and determine the sending status of each of the target upgrade packages according to the number of times each of the target upgrade packages is sent.

[0030] ​In the embodiments of the present specification, after determining the upgrade order of each energy storage battery to be upgraded, the same target upgrade package can be sent to each energy storage battery to be upgraded in the upgrade order. In each separate sending process, the sending failure may occur due to network interference or other accidental factors. In order to improve the success rate of subsequent upgrades, it is necessary to resend the target upgrade package after the sending failure, record the number of times each target upgrade package is sent, and determine the sending status of each target upgrade package based on the number of times it is sent. Among them, although the sending status may include successful sending and failed sending, regardless of whether the sending status is successful, as long as the sending status of the previous target upgrade package is determined, the target upgrade package needs to be sent to the next energy storage battery to be upgraded in the upgrade order.

[0031] In one possible implementation, the sending of the target upgrade package to each of the energy storage batteries to be upgraded based on the upgrade sequence includes: For any of the energy storage batteries to be upgraded, sub-packaging the target upgrade package according to the parameter information of the target upgrade package to obtain at least two upgrade sub-packages; All the upgrade sub-packages of the target upgrade package are sent to each of the energy storage batteries to be upgraded according to the upgrade sequence.

[0032] In the embodiment of the present specification, in the process of sending a target upgrade package to any energy storage battery to be upgraded, in order to prevent the target upgrade package from being too large, resulting in data packet loss and upgrade failure, the target upgrade package can be sent in sub-packages. Among them, when sending the sub-packages, the parameter information of the target upgrade package can be determined first, and the parameter information may include the number of sub-packages of the upgrade package, the size of the upgrade package and other information. Then, the target upgrade package is split according to the size information and sub-package information in the parameter information to obtain multiple upgrade sub-packages. Furthermore, the sub-package sending method of each upgrade sub-package sends all the upgrade sub-packages in the same target upgrade package to each energy storage battery to be upgraded according to the determined upgrade order.

[0033] In one possible implementation, determining the sending status of each target upgrade package according to the number of times each target upgrade package is sent includes: For any of the energy storage batteries to be upgraded, after the target upgrade package fails to be sent, the target upgrade package is resent, and the number of resends corresponding to the target upgrade package is counted; The retransmission times are compared with a preset maximum retransmission times, and the sending status of each target upgrade package is determined based on each comparison result.

[0034] In the embodiment of the present specification, in the process of sending a target upgrade package to any energy storage battery to be upgraded, each energy storage battery to be upgraded will feedback the receiving status after receiving the target upgrade package. When the reply is 1, it means that the reception is normal, and when the reply is 0, it means that the reception is abnormal. When the first target upgrade package fails to be sent and the receiving feedback reply is 0, it indicates that the first target upgrade package fails to be sent. The target upgrade package can be resent, and the number of resends corresponding to the target upgrade package is counted. At the same time, the number of resends is compared with the preset maximum number of resends. Generally, the preset maximum number of resends is set to 3. Further, the sending status of each target upgrade package sent to the energy storage battery to be upgraded is determined according to each comparison result, that is, when the number of resends is greater than 3 times and the reception is still abnormal, that is, when the reception is abnormal for three consecutive times, the sending status of the target upgrade package is judged to be a sending failure, and when the number of resends is equal to 0 or greater than 0 and less than 3 times, and the reception is still normal, the sending status of the target upgrade package is judged to be a sending success.

[0035] Step 204: After each of the sending states is characterized as being sent successfully, an upgrade instruction is sent to each of the energy storage batteries to be upgraded corresponding thereto.

[0036] The upgrade instruction is used to control each of the energy storage batteries to be upgraded to be upgraded based on the target upgrade package.

[0037] In the embodiment of the present specification, after sending the target upgrade package to each energy storage battery to be upgraded in the upgrade order, as long as the sending status of a certain sending process is monitored to be sent successfully, the upgrade instruction can be sent to the corresponding energy storage battery to be upgraded. After receiving the upgrade instruction, the energy storage battery to be upgraded is upgraded first according to the received target upgrade package. Other energy storage batteries to be upgraded are upgraded in the same way according to the sending status of the target upgrade package. Among them, when the sending status is characterized as failure, it means that the corresponding energy storage battery to be upgraded has not received the target upgrade package, and there is no need to send the upgrade instruction to the corresponding energy storage battery to be upgraded.

[0038] In one possible implementation, after each of the sending states is characterized as being sent successfully, sending an upgrade instruction to each of the energy storage batteries to be upgraded corresponding thereto includes: For any of the energy storage batteries to be upgraded, after the sending status is characterized as successful sending, determining that the upgrade version information of the target upgrade package and the current working information of the energy storage battery to be upgraded are received; When the upgraded version information and the current operation information both meet the reset condition, an upgrade instruction is sent to the upgraded energy storage battery.

[0039] In the embodiments of the present specification, for the upgrade process of any energy storage battery to be upgraded, after monitoring that the sending status corresponding to the energy storage battery to be upgraded is characterized as successful sending, in order to ensure whether the received target upgrade package version is consistent with the instruction version information in the upgrade instruction, the upgrade version information of the received target upgrade package can be determined first. At the same time, in order to avoid affecting the energy storage battery to be upgraded that is in operation, it is necessary to first monitor the current working information in the energy storage battery to be upgraded at this time. Then, the upgrade version information and the current working information are judged against the reset condition. When the upgrade version information is consistent with the instruction version information in the upgrade instruction, and the current working information is that the battery current is less than 1A, it indicates that the upgrade version information and the current working information both meet the reset condition, and the upgrade instruction is sent to the upgraded energy storage battery. When it is judged that the reset condition is not met, it is prohibited to send the upgrade instruction to the upgraded energy storage battery until the reset condition is met.

[0040] In one possible implementation, each of the energy storage batteries to be upgraded is provided with a program running area and a program temporary storage area; After each of the sending states is characterized as being sent successfully, an upgrade instruction is sent to each of the corresponding energy storage batteries to be upgraded, wherein the upgrade instruction is used to control each of the energy storage batteries to be upgraded to be upgraded based on the target upgrade package, including: After the sending status is characterized as successful sending, an upgrade instruction is sent to each corresponding energy storage battery to be upgraded, wherein the upgrade instruction is used to control each energy storage battery to be upgraded to move each target upgrade package from the program temporary storage area to the program running area, and execute the program corresponding to each target upgrade package in the program running area; The method further comprises: After each receiving state is characterized as a sending failure, a pause upgrade instruction is sent to each corresponding energy storage battery to be upgraded, and the pause upgrade instruction is used to control each energy storage battery to be upgraded to execute the historical program in the program running area.

[0041] In the embodiments of this specification, generally, the programs in the energy storage battery system to be upgraded are stored in the flash of the hardware MCU, including the boot program Bootloader and the application layer program, wherein the Bootloader is fixed, and the application layer program is updated each time it is upgraded. In order to avoid the situation where the energy storage battery system to be upgraded has no program to run and causes a crash due to an upgrade failure, the flash setting can be divided into 4 storage areas, numbered 1-4 respectively, wherein storage area 1 is the Bootloader running area, storage area 2 is the information area, which stores the main running parameters of the program and can be modified; storage area 3 is the program running area, which cannot be modified and can only be erased; storage area 4 is the program temporary storage area. When the target upgrade package starts to be sent, the energy storage battery system to be upgraded will first place the newly received target upgrade package in storage area 4. When the target upgrade package is received, the online upgrade platform sends an upgrade instruction to the energy storage battery system to be upgraded. When the energy storage battery system to be upgraded restarts and resets, it moves the target upgrade package in storage area 4 to storage area 3, and executes the new program corresponding to the target upgrade package after reset. If the receiving status is characterized by a sending failure, that is, the upgrade fails, the program package temporarily received in storage area 4 is erased, and the historical program in storage area 3 is still run, which can ensure that even if the upgrade of the energy storage battery program fails, the energy storage battery system to be upgraded can still work normally.

In some cases, the actions or steps recorded in the claims can be performed in an order different from that in the embodiments and still achieve the desired results. In addition, the processes depicted in the drawings do not necessarily require the specific order or continuous order shown to achieve the desired results.
