Abstract

The invention discloses an electric automobile charging system. The electric automobile charging system comprises a charging control board, wherein a central processing unit, an electric signal acquisition circuit, an overload protection circuit and an alarm circuit are arranged on the charging control board, the electric signal acquisition circuit is connected to a voltage transformer and a current transformer which are arranged on a charging gun, and the central processing unit is connected to the electric signal acquisition circuit, the overload protection circuit and the alarm circuit. According to the electric automobile charging system, the structure principle is simple, collection of the charging voltage and the current signal can be realized, meanwhile, overload protection can be realized, abnormal alarm of the power supply can be realized, and normal use of a charging pile is ensured.

Description

technical field [0001] The invention relates to the technical field of charging protection circuits, in particular to an electric vehicle charging system. Background technique [0002] A charging pile is an electric vehicle charging station. Charging piles are divided into floor-mounted charging piles and wall-mounted charging piles, which provide users with functions such as timing, electricity metering, and amount charging. [0003] The current charging pile has a certain protection mechanism, but the protection effect is poor, and it does not have an abnormal output voltage alarm function. Therefore, it is necessary to improve it. Contents of the invention [0004] The purpose of the present invention is to provide a charging system for electric vehicles to solve the problems raised in the background art above. [0005] In order to achieve the above object, the present invention provides the following technical solutions: a charging system for electric vehicles, inclu...
