Direct current charging pile field detection system and method

The invention discloses a direct current charging pile field detection system and method. The detection system comprises a main control unit, a direct current standard meter, a program control direct current electronic load and a test equipment interface. The detection method comprises the following steps of connecting a direct current charging pile firstly; starting the detection system; transmitting a control command of the main control unit to the direct current standard meter, the program control direct current electronic load and the test equipment interface through a test control bus; reporting an execution result to the main control unit through the test control bus after the control command is executed by the direct current standard meter, the program control direct current electronic load and the test equipment interface; comparing tested data with data of the charging pile in the main control unit; and finally obtaining a conclusion whether the charging pile is qualified or not. The detection system and the detection method are used for testing whether the direct current charging pile is qualified or not so as to ensure the benefits of a user and a person supplying the charging pile.
