Electric vehicle charging pile

Electric vehicle charging pile

The DC contactor for electric vehicles is characterized by high working voltage, which is nearly 20 times higher than the 24 V commonly used in automotive electrical appliances. When the DC circuit with a working voltage higher than 250 V is broken, it is difficult to extinguish the arc. After analyzing the causes of contact failure of the traditional product contact system and the action failure of the electromagnetic mechanical system, the reliability design concept is used to reduce the failure rate of the contact system and improve the reliability of the action and reset of the electromagnetic mechanical system.
