Portable detection apparatus for alternating-current/direct-current charging pile

The invention discloses a portable detection apparatus for an alternating-current/direct-current charging pile. A direct-current charging pile detection unit and an alternating-current charging pile detection unit are integrated with one portable apparatus, so that simultaneous detection of the direct-current charging pile and the alternating-current charging pile can be realized. The apparatus can take power from an alternating-current or direct-current charging machine and no external power supply is needed in field usage. The apparatus has a storage function and apparatus configuration parameters and information and a log of a tested power supply pile can be stored in a power-down mode. Because the apparatus has an external communication function, upper computer software can be used for configuring equipment or leading the information and the log of the tested power supply pile out. Besides, an external resistor box can be extended and thus functions of loaded testing on a charging pile and factor calibrat
