The invention discloses a test device for a charging pile. The test device comprises a main circuit unit and a control circuit unit. The main circuit unit comprises a converter, a bidirectional DC/DCconversion circuit and a function detection module for hardware. The control circuit unit comprises a main controller. The main controller communicates with the converter, the bidirectional DC/DC conversion circuit, an electricity meter and BMS through a first communication interface. The main controller communicates with a touch screen through a second communication interface. The main controllercommunicates with a host computer through a third communication interface. The BMS communicates with the charging post through a fourth communication interface. According to the test device for the charging pile and a test system for an AC, DC charging pile, the energy in a charging pile testing process can be used as the energy input of the charging pile, grid only provides the power lost by thedevice itself. The test device for the charging pile and the test system for the AC, DC charging pile can be applied to the charging piles input by AC or DC grid, can save energy, and can be used inthe test of the charging pile.
