Abstract

The invention relates to the technical field of software upgrading, and discloses a software upgrading method and device, a battery management system, a battery and an electric device. The method comprises the following steps: receiving an upgrading instruction; obtaining upgrading content corresponding to the upgrading instruction; and skipping to a corresponding bootstrap program according to the upgrading content, and executing an software upgrading operation according to the bootstrap program, wherein the bootstrap program comprises a first BootLoader program and a second BootLoader program, the first BootLoader program is used for upgrading the second BootLoader program, and the second BootLoader program is used for upgrading the first BootLoader program or an application program. According to the invention, problems of a BootLoader can be adjusted in time, and the BootLoader can be subjected to function perfection, change and communication protocol adjustment after the battery is packaged. The invention has relatively high reliability and flexibility, and effectively improves the software upgrading convenience.

Description

technical field [0001] The present application relates to the technical field of software upgrade, and in particular to a software upgrade method, device, battery management system, battery and electric device. Background technique [0002] After the traditional battery pack is assembled, the software needs to be updated due to requirements changes, design defects and other reasons. During the upgrade process, there may be upgrade errors due to operational errors, upgrade error files, software design defects, etc. At this time, the only way to correct the errors is to unpack and re-burn the software. [0003] However, the unpacking process is complicated and time-consuming. For battery packs with high air-tightness requirements, it will also cause air-tightness problems; Contents of the invention [0004] The embodiments of the present application at least partly solve the above problems, and improve the reliability of the battery management system during software upgrade...
