The Design Theory of DC Contactor for the Electric Vehicle
The requirements of DC contactor for the electric vehicle are small in volume and very reliable characteristic.Its characteristic is high working voltage, which is almost 20 times higher than 24V that the normal automotive electrics use.It is very difficult to control the arc when the breaking working voltage is over 250V DC circuit.After analyzing the reasons why the traditional products occur contact failure at contact system and occur movement failure at the electric-magnetic mechanical system, the reliable design concept is used, it can reduce the failure rate of the contact system during the period of operation, improve the reliability of the movement and reset of electro-magnetic mechanical system.We adopted the design features which can have the main contact system with permanent magnetic blow-out arc control performance, and it can achieve a DC contactor for electric vehicle with small in volume and high reliability.
