Abstract

The present invention discloses an alternating current and direct current charging pile calibration device at a same stage. The calibration device comprises an AC charging interface, a DC charging interface, an AC sampling circuit, a DC sampling circuit, a switching circuit, a calibration device processor and an electronic load. The AC charging interface and the DC charging interface are connected to the AC sampling circuit and the DC sampling circuit. The AC sampling circuit and the DC sampling circuit are connected to the switching circuit. The output end of the switching circuit is connected to the calibration device processor which is connected to the electronic load which is matched with the AC charging interface and the DC charging interface. According to the alternating current and direct current charging pile calibration device, alternating current charging pile calibration and direct current charging pile calibration can be realized at the same stage.

Description

technical field [0001] The invention relates to a charging pile verification device, in particular to a same-stage verification device for AC and DC charging piles. 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. Charging piles are divided into AC charging piles and DC AC charging piles. The charging pile is a power supply device that is fixedly installed outside the electric vehicle and connected to the grid to provide power for the on-board charger of the electric vehicle. [0003] The disadvantage of the existing products is that the charging pile verification device can only realize the verification of the DC charging pile or the verification of the AC charging pile, but cannot realize the verification of the AC and DC on the same platform. Contents of the invention [000...
