随着新能源汽车的发展,新能源汽车用的继电器其性能要求也不断提高。为了适用新能源汽车继电器负载的大电流、大负载、控制线圈低功耗要求,采用先进的继电器线圈控制方法,并对双线圈模式、PWM模式等控制方法进行了讨论。 With the development of new energy vehicles, new energy vehicles with the relay performance requirements are also rising. In order to apply the high current, heavy load and control coil of the new energy vehicle relay load, the advanced relay coil control method is adopted and the control methods of the double coil mode and the PWM mode are discussed.
