Running and charging interlocking device of electric vehicle

Abstract

The invention discloses a running and charging interlocking device of an electric vehicle. The device comprises low and high-voltage power distribution circuits, a charger and an energy storage system, wherein the anodes and the cathodes of the charger and the energy storage system are connected with a contactor K5 and a contactor K6 respectively; in a running state, the contactors K5 and K6 are disconnected, and the charger and the energy storage system are disconnected; when a charger plug is inserted into a charge port socket, a charging contactor is connected, the control signal of a charging contactor controller is just switched on, the contactors K5 and K6 are connected, the charger and the energy storage system are switched on, and the whole vehicle is in a charging state; and the input of a key switch 12V or 24V is just cut off, and the outputs of a key switch ACC gear and an ON gear do not carry charges so as to ensure that the vehicle does not run during charging. According to the technical scheme of the invention, interlocking of charging and running circuits is comprehensively realized by the high and low-voltage power distribution circuits, and hidden dangers of the electric vehicle in the running or charging state due to error operation of a driver in the practical running process are avoided.

AI Technical Summary

Benefits of technology

The inventor describes an electrical car charge-up lock that allows for efficient and easy access when needed while also preventing accidents from happening due to incorrect behavior on board. Additionally, it uses this technology to provide both direct current (“DC”) power and alternating current (AC) power at different voltages depending upon how long they have been charged up. This improves overall performance efficiency without sacrificing safety features like batteries or AC systems.

Problems solved by technology

This technical problem addressed in this patents relates to improving safe behavior at both regular charge (when there's no risk) and quick charging without causing potential accidents due to incorrect operations caused by overcharged connections with exposed contacts.
