Abstract

The invention discloses a vehicle relay energy saving control circuit having voltage protection. The vehicle relay energy saving control circuit having voltage protection includes a voltage protectioncircuit, an energy saving control circuit and a vehicle relay driving circuit. A relay coil voltage is stabilized on the condition that external wide voltage range input power conditions are met; according to characteristics of a relay, the minimum pull-in voltage and the minimum holding voltage are provided at a pull-in phase and a holding phase respectively, the coil consumption power is stabilized, through feedback closed-loop control, in the case of external voltage changes, the coil is guaranteed to consume the minimum power. The vehicle relay energy saving control circuit is advantagedin that the voltage protection circuit is set, the coil is guaranteed to operate in the normal operation voltage range, under high and low voltage conditions, the relay coil is effectively protected from being influenced or damaged.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle power supplies and switches, and in particular relates to a vehicle-mounted relay energy-saving control circuit. Background technique [0002] With the increasing energy crisis and environmental pollution, the development of high-efficiency, energy-saving, and zero-emission clean electric vehicles has become an inevitable trend in the development of the domestic and foreign automobile industries. With the requirements of the national standard GB / T 18384.3-2015 for personnel electric shock protection, the stability and reliability of the internal switching devices of electric vehicles, as well as the performance of energy saving and consumption reduction, have become an important link affecting the performance of electric vehicles. [0003] Due to the complexity of the internal working environment of electric vehicles, there are many high-power and high-power load devices, which is a test ...
