And the controller responds to the received starting instruction, skips to the APP area through the bootstrap program of the BOOT area, runs the program in the APP area, and then the battery management system enters a normal working state to execute a corresponding task.
In the normal operation process of the battery management system, the controller responds to the update notification received from the external device (shown in fig. 1) or the storage device (shown in fig. 2) of the battery management system, jumps from the APP area to the BOOT area, reads the version information and the check information of the upgrade program from the external device or the storage device of the battery management system through the BOOT program of the BOOT area, judges the integrity of the upgrade program and determines whether to upgrade. And if the upgrading is determined, erasing the data of the APP area, reading the upgrading program from the external equipment or the storage equipment, writing the upgrading program into the APP area, jumping from the BOOT area to the APP area after the upgrading program is successfully written, and running the upgrading program, so that the upgrading of the battery management system is completed.
As can be seen from the above description, in the related art, in the process of upgrading the battery management system, the APP area needs to jump to the BOOT area to execute the upgrade task, which causes the battery management system to fail to execute the main task and to work normally in the upgrade process, and the temporary abnormal working state may cause damage to the product and even cause a safety accident.
In order to solve the above technical problem, an embodiment of the present disclosure provides a method for upgrading a battery management system.
Before explaining the technical solutions provided by the embodiments of the present disclosure, an implementation environment related to the embodiments of the present disclosure is first explained.
As shown in fig. 3, an implementation environment related to an embodiment of the present disclosure includes a battery management system including a controller and a storage device (e.g., RAM) and an external device.
The controller comprises a BOOT BOOT area and a plurality of storage areas, wherein the BOOT BOOT area is used for storing BOOT programs for booting and running the battery management system, and each storage area is used for storing application programs (hereinafter referred to as 'programs') for realizing functions of balancing, protecting and the like of the battery management system. Further, the controller also comprises a plurality of information areas, each information area corresponds to one storage area and is used for storing data such as version information and verification information of the program corresponding to the storage area.
The storage device may include a plurality of program file areas each for storing an upgrade program, and an information area for storing version information, check information, and the like of the respective upgrade programs. The controller responds to the received starting instruction, the BOOT program is guided to jump to one of the storage areas in which the program is stored, the program in the storage area is operated, and therefore the battery management system enters a normal working state and executes tasks such as battery equalization, over-temperature protection and overvoltage protection.
It should be noted that fig. 3 is only illustrated that the controller includes two storage areas and two information areas and the storage device includes two storage areas and one information area.
Based on the implementation environment shown in fig. 3, an embodiment of the present disclosure provides a method for upgrading a battery management system. Fig. 4 is a flowchart illustrating a battery management system upgrade method according to an exemplary embodiment of the present disclosure, as shown in fig. 4, the method including the steps of:
s41, checking whether there is a target upgrade program corresponding to the program of the first storage area.
The first storage area may be a storage area to which a program currently running in the battery management system belongs, or may be any storage area in the controller.
In an optional implementation manner, it may be determined whether the version of the optional upgrade program is newer than the version of the program in the first storage area, and if the version of the optional upgrade program is newer than the version of the program in the first storage area, it is determined that the target upgrade program exists.
In specific implementation, as shown in fig. 5, version information corresponding to the program in the first storage area and version information identifying the upgrade program may be identified, and whether the version of the upgrade program is newer than the version of the program in the first storage area is determined according to the program in the first storage area and the version information of the upgrade program; and if the version information of the upgrading program is newer than the version of the program in the first storage area, determining that the target upgrading program exists. Further, if only one upgrading program of a program of which the version is new to the first storage area exists, taking the upgrading program as a target upgrading program; if there are a plurality of upgrade programs whose versions are newer than the program in the first storage area, the upgrade program whose version is the latest can be selected from the upgrade programs as the target upgrade program.
The version information corresponding to the program in the first storage area can be read from the information area corresponding to the first storage area.
The version information of the upgrade program may be read from a storage device inside or outside the battery management system, for example, from a corresponding information area of the storage device.
It should be noted that there may be only one or a plurality of alternative programs in the storage device. In the case that a plurality of alternative programs exist in the storage device, a complete alternative program with a newer version can be selected from the alternative programs as an upgrade program. For example, taking an example that the storage device has two upgrading programs (i.e., a first candidate program and a second candidate program), the verification information and the version information of the first candidate program and the second candidate program of the storage device may be identified respectively, whether the first candidate program is complete is determined according to the verification information of the first candidate program, and whether the second candidate program is complete is determined according to the verification information of the second candidate program; and if the first alternative program and the second alternative program are complete, selecting the version update of the first alternative program and the second alternative program as an upgrading program, and identifying the version information of the upgrading program.
S42, if it is checked that the target upgrade program corresponding to the program in the first storage area exists, the target upgrade program is written into the second storage area.
Wherein the second storage area may be any other storage area except the first storage area.
Specifically, the target upgrade program may be written into the second storage area with respect to the data in the second storage area.
And S43, jumping from the first storage area to the second storage area after the target upgrading program is successfully written into the second storage area, and running the target upgrading program.
By the battery management system upgrading method provided by the embodiment, whether a target upgrading program corresponding to the program in the first storage area exists is checked, if the target upgrading program is checked, the target upgrading program is written into the second storage area, and after the target upgrading program is successfully written into the second storage area, the first storage area jumps to the second storage area to operate the target upgrading program.
Further, since the controller reads the boot identifier of the second storage area after jumping to the second storage area, if the boot identifier is normal, a series of initialization tasks such as data initialization and Board initialization are performed first, and in order to avoid repeated execution of the initialization tasks, as shown in fig. 5, after the target upgrade program is successfully written into the second storage area, the controller may set the boot identifier of the second storage area to be abnormal, so that the controller may skip the initialization task after jumping to the second storage area, and directly run the target upgrade program, thereby improving the performance of the battery management system.
Further, in order to avoid the problem that the battery management system cannot return to the normal operation state after being failed to be upgraded, the method for upgrading the battery management system according to the embodiment further includes: and if the target upgrading program fails to be written, continuing to run the program of the first storage area. Therefore, after the upgrading of the battery management system fails, the battery management system cannot jump to the BOOT area or other storage areas, still stays in the current storage area, continues to run the currently running program, and further has no influence on the main task, so that the reliability of the battery management system is improved.
Further, in order to ensure that the battery management system can still jump to the target upgrade program after being restarted under the conditions of unexpected power failure and the like, as shown in fig. 5, the method further includes: and after the target upgrading program is successfully written, erasing data in the information area corresponding to the target upgrading program, and writing the version information and the verification information of the target upgrading program into the information area.

Specifically, determining the memory area to be jumped according to the version information and the check information of each program includes: the controller reads version information and verification information of the program of the corresponding storage area from each version information area respectively through a BOOT program of the BOOT area, judges whether the program is complete or not according to the verification information of the program of the storage area aiming at each storage area, and selects the storage area with the complete stored program from all the storage areas as a candidate storage area. And then, selecting the storage area with the latest version of the stored program according to the version information of the program of each candidate storage area, jumping to the storage area, and running the program of the storage area.
Illustratively, as shown in fig. 6, the controller includes two storage areas (i.e., storage area 1 and storage area 2) and two information areas (information area 1 and information area 2), wherein the storage area 1 stores a program 1, the storage area 2 stores a program 2, the information area 1 corresponds to the storage area 1, and is used for storing version information Ver1 and check information Sign1 of the program 1; the information area 2 corresponds to the storage area 2 for storing the version information Ver2 and the check information Sign2 of the program 2. The controller reads version information Ver1 and check information Sign1 of program 1 from information area 1 and version information Ver2 and check information Sign2 of program 2 from information area 2 through the BOOT program of the BOOT area. Next, it is determined whether the program 1 and the program 2 are complete (i.e., whether Sign1 is TRUE and Sign2 is TRUE) according to Sign1 and Sign2, respectively. If the program 1 and the program 2 are not complete (i.e. Sign1 ═ FALSE, Sign2 ═ FALSE), ending the program upgrading task; if the program 1 and the program 2 are both complete (i.e. Sign1 is TRUE, Sign2 is TRUE), selecting a storage area to which the program with the updated version belongs according to the respective version information, jumping to the storage area, and running the program in the storage area; if only one program is complete (i.e. Sign1 or Sign 2), the storage area to which the complete program belongs is selected, and the storage area is jumped to, and the complete program is run.
Based on the same inventive concept, the disclosed embodiments further provide a computer-readable storage medium, on which a computer program is stored, and the computer program, when executed by a processor, implements the steps of the battery management system operation method according to any of the embodiments.
