Alternating current charging pile system for electric vehicles

Abstract

The invention provides an alternating current charging pile system for electric vehicles. The alternating current charging pile system for the electric vehicles comprises a box body interior circuit system, a front end equipment circuit system and a wire inlet power supply; the box body interior circuit system comprises an alternating current charging pile control board, a circuit breaker I, a circuit breaker II, a lightning protector, an intelligent electric meter and a 24V power supply; the wire inlet power supply is divided into two paths via a terminal block; one path is connected with the circuit breaker I, a fuse protector, the intelligent electric meter and the alternating current charging pile control board in sequence; the other path is connected with the circuit breaker II, the 24V power supply and the alternating current charging pile control board in sequence; the lightning protector is merged between the intelligent electric meter and the fuse protector; the intelligent electric meter communicates with the alternating current charging pile control board via an RS485 interface; the alternating current charging pile control board is externally connected with a 4G box via a network interface; an intelligent mobile terminal communicates with the alternating current charging pile control board via the 4G network; user balance judgement and charging ordering are finished by an APP of the intelligent mobile terminal; and conversion from user balance into electric amount and charging and power-off control are finished by the alternating current charging pile control board.

Description

Technical field [0001] The invention belongs to the technical field of charging equipment, and specifically relates to an AC charging pile system for an electric vehicle. Background technique [0002] The function of the charging pile is similar to the refueling machine in a gas station. It can be fixed on the ground or wall and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential community parking lots or charging stations. It can be based on different voltage levels. Charge various types of electric vehicles. An AC charging pile is a charging device installed outside the electric vehicle, connected to the AC power grid, and providing AC power to the electric vehicle battery through the on-board charger. Generally, it has functions such as power metering, billing, communication, and control. In recent years, the central and local governments have given great support to electric vehicles. Now many cities have their own elect...

AI Technical Summary

Problems solved by technology

In recent years, the central and local governments have given great support to electric vehicles. Now many cities have their own electric vehicle promotion plans. The demand for electric vehicles has increased under the promotion of the government, but the problem of difficulty in charging electric vehicles has never been resolved. be effectively resolved

Existing charging piles generally have problems such as single function, low charging efficiency, high single-unit power, and large floor space.
