Problems solved by technology

When the general protection switch at the incoming line end encounters a fault and trips, all charging output circuits on the charging pile will stop charging the battery, and they can only be used after the maintenance personnel eliminate the fault. In this case, other vehicles using the charging pile The charging process may be delayed for a long time
In addition, the power-off operation after charging is usually done manually, which may disconnect the control switch when the battery is not fully charged or cause the battery charging time to be too long, shortening the service life of the battery

Abstract

The invention discloses a charging pile for an electric vehicle, comprising a main leakage protecting switch, a plurality of charging output loops, a current measuring device and a control device, wherein the main leakage protecting switch is connected with a power supply grid; the charging output loops are connected with the main leakage protecting switch and comprise output loop control switches and charging sockets; the current measuring device is used for measuring the current of the charging output loops; and the control device is used for controlling the on-off of the output loop control switches and the main leakage protecting switch according to a current value measured by the current detecting device. The charging pile for the electric vehicle has the advantages of simple structure, convenient use, safety and reliability.

Description

technical field [0001] The invention relates to a charging device, in particular to an electric vehicle charging pile. Background technique [0002] With the development and popularization of electric vehicles, there is an increasing demand for public charging devices. The currently used charging piles are usually connected to a general protection switch at the incoming line end connected to the grid, and multiple charging output circuits are set at the output end. Each output circuit has its own control switch, and the power can be cut off after the battery is fully charged. Protect. When the general protection switch at the incoming line end encounters a fault and trips, all charging output circuits on the charging pile will stop charging the battery, and they can only be used after the maintenance personnel eliminate the fault. In this case, other vehicles using the charging pile The charging process may be delayed for a long time. In addition, the power-off operation ...
