Embodiment 1

[0024] Such as figure 1 As shown, the present invention provides a method for stably upgrading the battery management system. This method is applicable to a single battery management system. The software and hardware that need to be satisfied are: a dedicated upgrade host computer, a communication conversion module, a battery management system, The upgrade protocol is supported in the battery management system program.

[0025] Based on the above software and hardware, the method for stably upgrading the battery management system of the present invention is specifically described as follows:

[0026] a) When the battery management system meets the upgrade conditions, the dedicated upper computer sends the "command to enter the upgrade state" with a period of 100ms, until it receives a reply from the battery management system to "response command to enter the upgrade state" and then stops. At this time, the battery management system enters the upgrade process state.

Abstract

The invention discloses a method for stably upgrading a battery management system, which adopts an interactive upgrading mode, a single small data volume upgrading function, a fixed frame format and CRC16 verification function, an error retransmission function and a delay retransmission function, eliminates error data generated by interference, and ensures smooth and accurate operation in the whole upgrading process.

Description

technical field [0001] The invention relates to the technical field of battery management systems, in particular to a method for stably upgrading the battery management system. Background technique [0002] With the development of technology and the progress of society, the use of lithium-ion batteries is becoming more and more extensive. Due to the instability of lithium-ion batteries, the battery management system has become an indispensable part of it. At the same time, the battery management system often works in a more complex environment, and the upgrade methods based on serial communication or TCP communication are easy to receive interference, resulting in communication failure and data errors. Even during the upgrade process, if certain measures are not taken, it is easy to cause the upgrade to fail. Therefore, how to stably and smoothly upgrade the battery management system in a complex electromagnetic environment has become an urgent problem to be solved. Conte...
