The China patent with the application number of CN201710353365.6 provides a battery management system which comprises a gas sensing module, a smoke sensing module, a temperature sensing module, a control module, a fire extinguishing module and an early warning module. The gas sensing module senses the concentration of the thermal runaway gas in the battery box and transmits the sensed concentration value of the thermal runaway gas to the control module. The smoke sensing module senses the concentration of smoke in the battery box and transmits the sensed concentration value of the smoke to the control module. The temperature sensing module senses the temperature of the battery box and transmits the sensed temperature value to the control module. The control module compares the received concentration value of the thermal runaway gas, the smoke concentration value and the temperature value with corresponding reference values, and determines an early warning level according to the comparison result.
