An electric vehicle AC charging pile detection system and detection method thereof

Abstract

The invention discloses an electromobile AC charging pile detection system and method. Detection for an electromobile AC charging pile by a practical vehicle or vehicle-mounted battery system needs alarge place and is high cost and low in detection efficiency. The detection system comprises a master control module, a charging gun connecting socket, an electric energy metering unit, an AC contactor, a power analyzer, a load module, a PC control end and an oscilloscope. Manual and automatic control in the detection process is realized, switching in a vehicle-mounted charger can be simulated, voltage signals required for determining the connecting state of the charging gun is provided, and PWM signals output by a control and guidance circuit of the AC charging pile can be monitored in real time; charging state information can be collected accurately and displayed in a PC in the charging process, compared with display data of a charging pile body and further determined; and the load magnitude can be adjusted by the PC according to practical requirements, the practical charging conditions of different models of equipment can be simulated, and the charging pile is tested fully.

Description

technical field [0001] The invention belongs to the field of intelligent charging of electric vehicles, and in particular relates to an electric vehicle AC charging pile detection system and a detection method thereof. Background technique [0002] With the increasing number of electric vehicles, the demand for electric vehicle AC charging piles as a kind of electric vehicle charging equipment is also increasing.
