Description

Technical Field

[0001] The present invention relates to the field of battery parallel control, and in particular to an address allocation and program upgrade method, system and medium for parallel operation of multiple battery modules. Background Art

[0002] The existing multi-battery parallel technology uses a single fixed address method for communication, and most program upgrade methods still use a single unit upgrade method.

[0003] The existing single-machine fixed address method for communication generally adopts the following two methods. The first is to write the machine address into the internal control program of the battery, but it will cause the control program of each machine to be different, resulting in difficulties in the production process; the second is to use the internal control program of the battery to read the external dial switch to determine the different machine addresses, but when the battery is installed in place, it is sometimes difficult to dial the code due to the installation position, resulting in inconvenience in paralleling.

[0004] Moreover, the existing program upgrade method still adopts a method of upgrading a single machine, and the program will be upgraded one by one during the program upgrade, which makes the operation complicated. Summary of the invention

[0005] In order to overcome the existing single-machine fixed address method for communication in the above background technology, the following two methods are generally used. The first is to write the machine address in the internal control program of the battery, but it will cause the control program of each machine to be different, resulting in difficulties in the production process; the second is to use the internal control program of the battery to read the external dial switch to determine the different machine addresses, but when the battery is installed in the right position, it is sometimes difficult to dial the code due to the installation position, resulting in inconvenience in parallel. Moreover, the existing program upgrade method still adopts the method of upgrading for a single unit, and the program will be upgraded one by one during the program upgrade, resulting in the disadvantage of complex operation. The purpose of the present invention is to provide an address allocation and program upgrade method for paralleling multiple battery modules.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solution:

[0007] In a first aspect of the present invention, a method for address allocation and program upgrade of a multi-battery module parallel system is provided, wherein each battery module in the multi-battery module is connected in sequence, the multi-battery module comprises a plurality of battery modules, the first battery module is connected as a main battery module and a control switch in a connection sequence, and the remaining battery modules are connected as auxiliary battery modules: the address allocation is performed according to the connection sequence of each battery module, specifically comprising: an address allocation stage and a program upgrade stage:

[0008] The address allocation stage includes the following:

[0009] The address of the main battery module is allocated as follows: the main battery module identifies the pressing time threshold of the control switch, and after exceeding the time threshold, enters the address allocation program of the main battery module: sets the main battery module address, and the main battery module sends a shutdown and restart instruction to all auxiliary battery modules. When all auxiliary battery modules are shut down and restarted, the main battery module sends an address setting instruction and the main battery module address to all auxiliary battery modules; after all auxiliary battery modules receive the address setting instruction and the main battery module address, they enter their respective address allocation programs: set their respective addresses to (main battery module address - address interval), and send instructions to the main battery module that the local address has been set; after the main battery module receives the instruction that the local address has been set, it no longer sends the main battery module address, and exits the address allocation program of the main battery module, completing the address allocation;

[0010] The address of the current auxiliary battery module is allocated as follows: the current auxiliary battery module sends a shutdown and restart instruction to the remaining auxiliary battery modules. When the remaining auxiliary battery modules are shut down and restarted, the current auxiliary battery module sends an address setting instruction and the current auxiliary battery module address to the remaining auxiliary battery modules; after receiving the address setting instruction and the current auxiliary battery module address, the remaining auxiliary battery modules enter their respective address allocation procedures: set their respective addresses to (current auxiliary battery module address - address interval), and send instructions to the current auxiliary battery module that the local address has been set; after receiving the instruction that the local address has been set, the current auxiliary battery module no longer sends the current auxiliary battery module address, and exits the address allocation procedure of the current auxiliary battery module, completing the address allocation;

[0011] The program upgrade phase includes the following:

[0012] The assigned address of each battery module is read through the upgrade program code package to complete the program upgrade of the battery module itself, wherein each upgrade program code in the upgrade program code package is respectively configured with an address identification code, and the address identification code is used to identify the assigned address of each battery module, and they correspond one to one.

[0013] The beneficial effects of the present invention are as follows: without changing the battery performance, an address allocation program is added to the internal control program of the battery, the address allocation program of the main battery module is entered first, and through the instructions and address interactions between the main battery module and the auxiliary battery module, the respective address allocation programs are entered, and the respective address allocations are completed in sequence according to the connection sequence. The address allocation program of each battery module is the same, which solves the problem of difficult production processes; when the program is upgraded, it will automatically match and upgrade according to the addresses of different battery modules, without the need to upgrade the program one by one, which greatly increases the efficiency of producers and operators.

[0014] In some possible implementations, after each battery module sets its local address, it sets a flag indicating that its local address has been set. The flag indicating that its local address has been set is used to inform the respective address allocation programs that the local address of the current battery module has been set, thereby preventing the address allocation programs from continuing to allocate addresses, resulting in missed addresses and inaccurate address allocation.

[0015] In some possible implementations, each battery module clears the last local address setting flag before setting the local address, to prevent the last local address setting flag from interfering with the current address allocation, causing address omission and inaccurate address allocation.

[0016] In some possible implementations, each battery module maintains the already set local address when it does not receive the address setting instruction, so as to prevent each battery module from continuing to participate in the allocation after the address is allocated, resulting in confusion in the address allocation. At the same time, the address setting instruction is received as a sign that the local address allocation is completed, so as to facilitate the subsequent address allocation of other unallocated battery modules.

[0017] In a second aspect of the present invention, an address allocation and program upgrade system for parallel operation of multiple battery modules is provided, wherein each battery module in the multiple battery modules is connected in sequence, the multiple battery modules include a plurality of battery modules, the first battery module is connected as a main battery module and a control switch in a connection sequence, and the remaining battery modules are connected as auxiliary battery modules: the address allocation is allocated according to the connection sequence of each battery module, and the system includes: an address allocation module and a program upgrade module,

[0018] The working process of the address allocation module is as follows:

[0019] The address of the main battery module is allocated as follows: the main battery module identifies the pressing time threshold of the control switch, and after exceeding the time threshold, enters the address allocation program of the main battery module: sets the main battery module address, and the main battery module sends a shutdown and restart instruction to all auxiliary battery modules. When all auxiliary battery modules are shut down and restarted, the main battery module sends an address setting instruction and the main battery module address to all auxiliary battery modules; after all auxiliary battery modules receive the address setting instruction and the main battery module address, they enter their respective address allocation programs: set their respective addresses to (main battery module address - address interval), and send instructions to the main battery module that the local address has been set; after the main battery module receives the instruction that the local address has been set, it no longer sends the main battery module address, and exits the address allocation program of the main battery module, completing the address allocation;

[0020] The address of the current auxiliary battery module is allocated as follows: the current auxiliary battery module sends a shutdown and restart instruction to the remaining auxiliary battery modules. When the remaining auxiliary battery modules are shut down and restarted, the current auxiliary battery module sends an address setting instruction and the current auxiliary battery module address to the remaining auxiliary battery modules; after receiving the address setting instruction and the current auxiliary battery module address, the remaining auxiliary battery modules enter their respective address allocation procedures: set their respective addresses to (current auxiliary battery module address - address interval), and send instructions to the current auxiliary battery module that the local address has been set; after receiving the instruction that the local address has been set, the current auxiliary battery module no longer sends the current auxiliary battery module address, and exits the address allocation procedure of the current auxiliary battery module, completing the address allocation;

[0021] The working process of the program upgrade module is as follows:

[0022] The assigned address of each battery module is read through the upgrade program code package to complete the program upgrade of the battery module itself, wherein each upgrade program code in the upgrade program code package is respectively configured with an address identification code, and the address identification code is used to identify the assigned address of each battery module, and they correspond one to one.

[0023] In some possible implementations, after each battery module sets its local address, it sets a flag indicating that its local address has been set.

[0024] In some possible implementations, before setting the local address of each battery module, the flag indicating that the local address has been set last time is cleared.

[0025] In some possible implementations, when no address setting instruction is received, each battery module maintains the set local address unchanged.

[0026] According to a third aspect of the present invention, a computer-readable storage medium is provided, on which a computer program is stored. When the computer program is executed by a processor, the steps of the address allocation and program upgrade method for parallel operation of multiple battery modules as described in any one of claims 1 to 4 are implemented.
