Abstract

The present invention provides an AC charging post calibration device. The device comprises a charging post interface, an electrical parameter acquisition module, a control and guide module and a load interface. The electrical parameter acquisition module is respectively connected with the charging post interface and the load interface via live lines L1, L2 and L3, and a zero line N. The control and guide module is respectively connected with the charging post interface and the load interface via a ground line PE, a charging connection confirming line CC and a control confirming line CP. According to the technical scheme of the invention, during the charging process of an AC charging post, the current value and the voltage value of the AC charging post in the normal charging state can be measured in real time. Meanwhile, the statistics on the electric energy is conducted in real time. Therefore, the device provides detection data for the field verification, the testing, the sampling and the annual inspection of AC charging posts.

Description

technical field [0001] The invention relates to the field of AC charging pile detection, in particular to an AC charging pile verification device. Background technique [0002] With the continuous popularization of new energy electric vehicles, AC charging piles for electric vehicles, as the basic supporting facilities for new energy electric vehicles, are closely related to people's lives. AC charging piles are divided into AC charging piles and DC AC charging piles. Among them, AC charging piles are fixedly installed outside the electric vehicle and connected to the AC power grid to provide AC power supply for the electric vehicle on-board charger. At present, the on-site verification device for AC charging piles is still in the state of development and research. [0003] At present, the AC electric energy meter verification device of the AC charging pile and the electric energy metering device of the single-phase wide-range AC charging pile in the prior art have solved t...
