Method for forming battery running system of electric vehicle and system said above

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 ...

Problems solved by technology

[0005] The purpose of the present invention is mainly to solve the problems in the prior art that the battery management system consumes a lot of energy, the energy waste is serious, the integrally packaged equalization module is easily damaged, and the safety of the electric vehicle is reduced, and an electric vehicle battery is proposed The composition method of the management system, through the establishment of an independent monitoring function module and a charging equalization module of the battery management system, realizes the reasonable separation and organic coordination of the functions of the electric vehicle under different conditions. The single battery is monitored and alarmed. When parking and charging, a charging equalization module is added to the monitoring module to automatically balance the battery pack.
