Abstract

The invention discloses a charging pile insulation detection system and method. The system adopts a charging pile insulation detection circuit to carry out insulation detection on a charging pile, and comprises a bus voltage measurement module which is used for measuring the voltage to ground of a positive bus, the voltage to ground of a negative bus and the voltage between the positive bus and the negative bus of the charging pile insulation detection circuit; the insulation resistance calculation module is used for calculating positive bus-to-ground insulation resistance and negative bus-to-ground insulation resistance in the charging pile insulation detection circuit according to the positive bus-to-ground voltage, the negative bus-to-ground voltage and the voltage between the positive bus and the negative bus; and the insulation state judgment module is used for judging the insulation state of the charging pile according to the ground insulation resistance of the positive bus and the ground insulation resistance of the negative bus. The technical problem of insulation detection of the charging module of the charging pile in the prior art is solved.

Description

technical field [0001] The present application relates to the technical field of charging pile insulation detection, and in particular, to a charging pile insulation detection system and method. Background technique [0002] With the rapid development of charging pile charging module technology and rechargeable battery technology, the maximum voltage level of DC charging piles has risen from 750V to 1000V. In public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations, various types of electric vehicles can be charged according to different voltage levels. However, the insulation failure of the charging module of the charging pile may cause electric shock accidents, so the insulation detection is very important for the safe charging of the charging pile. [0003] Aiming at the problem of insulation detection of the charging module of the charging pile in the related art, no effective solution has been prop...
