The counter of the public storage unit is used for counting the successful downloading times of the complete OTA upgrade package, and because the OTA upgrade package is related to battery hardware information and/or BMS system information of the battery pack, a plurality of battery pack modules in the battery pack system in the same area can timely delete OTA upgrade package data in a storage area of the public storage unit to save storage space of the public storage unit if the battery hardware information of the battery pack modules is the same, and the counted successful downloading times of the OTA upgrade package are the same as the number of the battery pack modules in the system.
By the method, any battery pack module of the regional battery pack can download the OTA upgrade package and execute data upgrade in a stable or unstable network environment, if the first battery pack module enters a signal shielding region such as an indoor space in the upgrade process, the upgrade requirement is automatically sent to an instruction area of a public storage unit, and the other battery pack modules are idle to continuously access a server and continuously download breakpoint, so that the OTA data download is completed. The technical problems that the regional battery pack system has the advantages of data saving and stable downloading caused by complex environments are effectively avoided. And the system upgrading efficiency and upgrading effect are improved.
