The functions and roles of the battery management system (BMS) can be detailed as follows:

BATTERY MANAGEMENT SYSTEM, which is an important link between the battery and downstream equipment, can improve the utilization of the battery, prevent the battery from overcharging and over discharging, prolong the life of the battery, and monitor the status of the battery.

1、Protect the battery cell and battery pack from damage;
2、Make the battery work in the right voltage and temperature range;
3、Keep the battery operating under the right conditions;
4、Battery parameter detection: including total voltage, total current, single cell voltage detection, temperature detection, insulation detection, collision detection, impedance detection, smoke detection, etc;
5、Battery status establishment: including SOC, SOH, SOF.
6, online diagnosis: fault including sensor failure, network failure, battery failure, battery overcharge, over discharge, over current, insulation failure, etc.;

7、Battery safety protection and alarm: When a fault is diagnosed, the BMS will report the fault to the system and cut off the circuit to protect the battery from damage;
8, charging control: slow charging and fast charging control;
9、Battery Consistency Control: Collect the single voltage information and use the equalization method to make the battery consistent, the equalization method has dissipative and non-dissipative;
10、Thermal management function: monitor the temperature of each observation point of the battery pack during charging and discharging, and decide whether to open heating and cooling;
11, network functions: including online calibration and health, online program download. Usually use CAN network;
12, information storage: storage of key data such as SOC, SOH, charge and discharge amperage, fault codes, etc..

It can be seen that the battery management system is not only closely linked to the battery, but also closely linked to the upstream and downstream systems. Compared to other products, the failure of the battery management system is relatively high and difficult to deal with.
