【 摘 要 】

Design a charging pile electric energy verification device to improve the electric energy measurement accuracy of the charging pile. The device is mainly used for detecting whether the charging pile can be correctly configured, including a tariff period, a billing unit power, a billing rate, and the like, and detecting the communication reliability of the charging station. The test charges the pile output data by the broadband current comparator. Through RS485 communication mode, the instrumentation communication with the charging pile is always used to improve the accuracy of detection and measurement. The design and development of the DC charging pile verification device promoted the construction of the charging infrastructure and solved the charging problem of the electric vehicle.
