Analysis of working principle of battery Management System (BMS)

• Analysis of working principle of battery Management System (BMS)

1. Compared with the range anxiety, the safety anxiety of pure electric vehicles is a topic that the owners pay more attention to.

2. Data show that 80% of the spontaneous combustion accidents of new energy vehicles occur during charging or within 1 hour after being fully charged.

3. The thermal management effect of new energy vehicles will affect more than 40% of the endurance effect.

Car buyers who ignore battery safety and blindly focus on "high range" and "high energy density" may one day regret it.

Safety accidents of electric vehicles will be greatly reduced if fires caused by charging can be effectively avoided. At this point, we need to know about BMS.

Battery Management System (BMS) is an indispensable and important component of electric vehicles. It is the center of power battery management and monitoring. It manages, maintains, and monitors each module of the battery, and shoulders the responsibility of preventing over-charge and over-discharge of the battery, extending the service life of the battery, and helping the normal operation of the battery.

A battery management system (BMS) is an important link between the vehicle battery and the electric vehicle. Its main functions include real-time monitoring of battery physical parameters, battery status estimation, online diagnosis and early warning, balanced management of charge and discharge and precharge control, thermal management, and so on. Which of the above functions is not good, will make the battery fatal harm.
