Charging piles, the most important supporting facility for charging, are attracting people’s attention. In the charging process, the output voltage of a charging pile is up to several hundred volts. Any failure in the insulation or communication system of charging equipment may lead to charging accidents, even casualties.
The aging failure of the equipment and components inside charging piles also affects the safety of charging piles in use.
Considering that gas explosion may cause thermal runaway of battery module in the actual scene, the existence of high-temperature zone may be longer and the temperature peak may be higher.
