Abstract

The invention is used to implement the management for separating and combining the function of electric automobile at different states by building a battery management system comprising a monitoring module and a charging equalization module. When the electric automobile is in normal running state, said system is working at a monitor mode that monitors each battery in the battery pack, and the charging plug socket in the charging equalization module box is in cutting-off state. When the electric automobile stops to make charge, said system is working at the charging equalization mode that adds the charging equalization box on the monitoring module to automatically make equalization charging for the battery pack. The charging equalization module box hasn't to be installed on one electric automobile, but can be used by multi electric automobiles.

Description

technical field [0001] The present invention relates to the technical field of electric vehicle management systems, in particular to a method for constructing an electric vehicle battery management system and a system thereof. Background technique [0002] Electric vehicles have become the development direction of future vehicles. They use high-power battery packs as the driving energy. They have the characteristics of low pollution, low noise, and energy saving. At present, some large-scale power stations, important communication equipment, and electric vehicles are equipped with high-power power battery packs. These power battery packs, especially lithium-ion power battery packs, use low-voltage single batteries in series to obtain high-voltage output. Main motor power supply. The performance and quality of each single battery in this series power supply mode is directly related to the power performance, quality and reliability of electric vehicles. The life of a single ...
