Problems solved by technology

The electrical signal passed through the charging connection device is the actual electrical signal received by the electric vehicle. Since the current charging connection device does not have a detection port, it is impossible to measure the actual electrical signal of the charging connection device (that is, received by the electric vehicle) detection

Abstract

The invention provides an electric vehicle AC charging connection device with a measurement and detection port. A detection port is arranged at a charging connection device end of an AC charging point; the electromagnetic induction and equivalent ampere-turns principles are adopted to convert the AC in the charging connection device into a voltage or current signal with measurable measurement standards, and the electric signals are measured and detected. The electric vehicle AC charging connection device with a measurement and detection port can detect the actual consumed electric energy of electric vehicles, can detect the actual electric signals received by the electric vehicle, and can detect the charging point of the electric vehicle without opening a shell of the charging point for wiring, so as to facilitate the detection process of detection personnel, improve the detection efficiency, and also improve the detection reliability and security greatly. The electric vehicle AC charging connection device with a measurement and detection port can input standard signals and automatically calibrate the current measurement error.

Description

technical field [0001] The invention relates to the field of electric vehicle charging facilities, in particular to an electric vehicle AC charging connection device with a metering detection port. Background technique [0002] As a national strategic emerging industry, the electric vehicle industry has received strong support from the state for its industrial development. As the main body of the industry, electric vehicles and charging facilities are rapidly entering people's daily lives. [0003] At present, the electric vehicle AC charging piles on the market are mainly composed of a display module, a control module, a billing module, a communication module, a charging connection device, an electric energy meter and a host casing. The main function is to complete the charging and charging of electric vehicles. Since it involves trade settlement, the AC charging pile as a whole is used as a measuring instrument, and the electrical values ​​involved need to be traced. At...
