The present disclosure relates to a battery management system upgrade and operation method, a controller, a battery management system and a storage medium. The battery management system upgrade method includes: checking whether there is a target upgrade program corresponding to the program in the first storage area; When the target upgrade program exists, write the target upgrade program into the second storage area; after the target upgrade program is successfully written into the second storage area, jump from the first storage area to the second storage area. The second storage area runs the target upgrade program. With the technical solution provided by the present disclosure, the battery management system can be upgraded while the battery management system is running, ensuring that the main task of the battery management system will not be destroyed, and running the target upgrade program after the upgrade program is successfully written, ensuring that the battery management system Always in working condition, seamless upgrade of the battery management system is achieved.
Description
technical field [0001] The present disclosure relates to the field of electronic technology, and in particular, to a method for upgrading and operating a battery management system, a controller, a battery management system and a storage medium. Background technique [0002] With the development of electronic technology, the pace of introducing new products to the market is gradually accelerating. In order to respond to the market's need for product function upgrades and to repair potential product problems, it has become an inevitable task for manufacturers to update product software regularly or irregularly. [0003] IAP (In Application Programming) is a common method used to upgrade product software. In the related art, the FLASH area of the main board of the product is usually divided into two logical areas, that is, a boot BOOT area for booting and software updating and an application program APP area for running software. When the product is working normally, the ma...
