Problems solved by technology

[0003] 1. With the increase in the amount of BMS program code, the time-consuming to update the program through the existing methods online (CAN / RS32 / U disk / SD card / GPRS / WIFI, etc.) is constantly increasing, which is necessary for BMS mass production and on-site update Maintenance is very inconvenient;
[0004] 2. The existing program update method adopts the method of updating the entire chip program, and any abnormality during the upgrade process will cause the entire system to fail to operate normally

Embodiment 1

[0045] Embodiment 1 of the present invention provides a method for quickly updating BMS application programs, figure 1 It is a flow chart of the method of Embodiment 1 of the present invention, please refer to figure 1 , the method of the embodiment of the present invention includes the following steps:

[0046] S101. Allocate the BMS program to its storage area in the ROM according to the functional modules;

[0047] S102. Add an external memory in the BMS, and when the module is updated, first receive and save the new module program to the external memory,

[0048] S103, judging whether there is an abnormal situation in the module update;

[0049] S104. If there is no abnormal situation, perform an integrity check on the entire module program after receiving the entire module program, and update the program to the corresponding internal storage area after the check is successful;

[0050] S105. If an abnormal situation occurs, the backup program is restored to the origina...

Abstract

The present invention discloses a BMS application rapid update method and update system. The method comprises the following steps: (1) allocating a BMS program to a storage region of the BMS program in a ROM according to a functional module; (2) adding an external memory in the BMS, and when updating the module, receiving a new module program and storing the new module program into the external memory; (3) determining whether an abnormal condition exist in module updating; (4) if the abnormal condition does not appear, performing an integrity check on the a whole module program after completing reception of the whole module program, and after the check succeeds, updating the program into a corresponding internal storage region; and (5) if the abnormal condition appears, restoring a backup program to the original module, and restoring a system to an original state. The system comprises a functional module division subsystem, an external storage subsystem, an anomaly determination subsystem, an internal storage subsystem and an abnormality restoration subsystem, which are connected sequentially. By means of the method and system disclosed by the present invention, online upgrade time of the BMS application can be shortened, and a system crash caused by BMS upgrade anomaly can be prevented.

Description

technical field [0001] The present invention relates to the technical field of electric vehicles, and more specifically, relates to a method for quickly updating BMS application programs and an updating system. Background technique [0002] With the promotion and application of new energy electric vehicles, the output of BMS (Battery Management System) has also increased, and the time taken for the application program upgrade function in the BMS production and maintenance process has also increased accordingly. The update method in the prior art mainly There are following two defects: [0003] 1. With the increase in the amount of BMS program code, the time-consuming to update the program through the existing methods online (CAN / RS32 / U disk / SD card / GPRS / WIFI, etc.) is constantly increasing, which is necessary for BMS mass production and on-site update Maintenance is very inconvenient; [0004] 2. The existing program update method adopts the method of updating the entire c...
