Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0027] The present invention can solve the problem that the system cannot run the application program when the remote upgrade using the communication interface fails, and the problem that the BMS system cannot fall back to the required historical version of the application program as required. In the present invention, by setting two backup program storage areas and adopting an exception handling mechanism, the update of the BMS system has a strong self-recovery capability, greatly improving the reliability of the software update process, and especially effectively preventing the system update from ...

Abstract

The invention discloses an application program version returning method based on BMS Bootloaderupgrade. The method comprises the following steps of (1) entering a working state when a BMS module is power on, reporting a current software version number to the BMS module by a host computer, and checking an update bit on FLASH; (2) when a system receives an update command sent by a control module, carrying out software update; (3) when the update is unsuccessful, returning to original version application program running, or returning to required history version application program running according to the actual condition. According to the application program version returning method based on BMS Bootloaderupgrade provided by the invention, two backup program storage areas are arranged, and an exception handling mechanism is adopted, so that the update of the BMS system has stronger self-recovery capability, the reliability of the software update process is greatly improved, the phenomenon of system boot failureoccurred after system update can be effectively prevented particularly, and higher practical value is achieved.

Description

technical field [0001] The invention belongs to the technical field of BMS system upgrading, and more specifically relates to a method for rolling back application program versions based on BMSBootloader upgrading. Background technique [0002] The internal structure of electric vehicles is complex, and the high-voltage battery pack is carried inside, which is associated with certain risks locally. Therefore, the way for after-sales personnel to upgrade the BMS system application program is mainly to perform remote online upgrades through serial ports or CAN and other communication methods. During the upgrade process, due to communication failure and other reasons, the upgrade will fail, and the original historical version program will be lost, so that the application program needs to be updated repeatedly, which affects the normal operation of the electric vehicle. [0003] The traditional method of upgrading the application of the BMS system is to use the bootloader at the...
