Abstract

The invention relates to an alternating current charging post for an electric automobile. The alternating current charging post comprises a wiring terminal part and a metering circuit part, wherein the wiring terminal part comprises a verification terminal; the metering circuit part comprises a metering management control unit, a power supply module, a key board, a card reader, a charging socket, an alternating current contactor, a single-phase electric energy meter and an emergency stop switch; the power supply module is used for supplying power to the metering management control unit; the key board and the card reader are connected to the input end of the metering management control unit; the output end of the metering management control unit is connected with the electric automobile through the charging socket; the output end of the metering management control unit is connected with the emergency stop switch through the alternating current contactor; the verification terminal is connected with the single-phase electric energy meter; and the single-phase electric energy meter is connected with the metering management control unit. The alternating current charging post disclosed by the invention has the advantages of reasonable and novel design and high creativity; and the verification of metering parameters can be directly carried out without opening a charging post door and the on-site verification efficiency of a charging and metering device can be greatly increased.

Description

technical field [0001] The invention relates to a charging device capable of charging electric vehicles and conforming to the verification regulations of measuring instruments, in particular to an AC charging pile for electric vehicles, which belongs to the innovative technology of AC charging piles for electric vehicles. Background technique [0002] At present, the AC charging device for electric vehicles on the market is mainly composed of a charging switch, a metering device, a control management system, and a charging interface. AC charging piles are metering equipment because they involve the measurement and collection of user charging fees. However, if the existing charging pile needs to verify its measurement parameters, it is necessary to open the maintenance door of the charging pile, and then verify the electric energy meter inside. Such an operation does not conform to the verification regulations of measuring instruments, and the measurement verification time o...
