Abstract

The invention provides a grounding and phase dislocation detecting circuit of alternating current charging equipment, and relates to the field of equipment detection. The grounding and phase dislocation detecting circuit of the alternating current charging equipment comprises a live wire, a zero wire, a ground wire, a transformer and a controller; the ground wire is connected with the live wire and the zero wire separately, a primary coil of the transformer is connected between the ground wire and the zero wire, and a secondary coil of the transformer is electrically connected with the controller; the transformer is used for sensing voltage between the zero wire and the ground wire; the controller is used for determining the grounding and phase dislocation state of the alternating currentcharging equipment according to the voltage of the secondary coil of the transformer. The grounding and phase dislocation detecting circuit of the alternating current charging equipment has the advantage of more accurately determining the grounding and phase dislocation state.

Description

technical field [0001] The present application relates to the field of equipment detection, in particular, to a grounding and phase-wrong detection circuit for AC charging equipment. Background technique [0002] With the improvement of energy saving and environmental protection awareness, the new energy vehicle market is becoming more and more mature. For new energy vehicles, AC charging equipment is a must. [0003] However, many existing AC charging equipment do not have the function of grounding and phase error detection. Even if some AC charging equipment has the function of grounding and phase error detection, the detection circuit is not isolated from the AC power grid and is easily affected by the harmonic interference of the AC power grid. A problem that makes the detection inaccurate. Contents of the invention [0004] The purpose of this application is to provide a grounding and phase error detection circuit for AC charging equipment to solve the problem of ina...
