Abstract: A charging pile includes a power system and a charging terminal. The power system includes a first power unit, a second power unit, a power control unit, and a heat sink. The first power unit is connected to the second power unit, and the first power unit and the second power unit have same output voltages and same output currents. The power control unit is configured to control the output voltages and the output currents of the two power units. The charging terminal includes a charging control module, a direct-current distribution unit, and a charging plug. The charging plug is configured to connect to a to-be-charged battery and charge the to-be-charged battery. The direct-current distribution unit is configured to allocate a power supply to the charging plug. The charging control module is configured to bill and display the charging.

Abstract: A charging pile system comprising a system input bus, charging pile circuit groups, a controller, a power allocation unit, and charging terminals. The power allocation unit comprises a first switch group, a second switch group, and a third switch group. The first switch group comprises first switching devices, the second switch group comprises second switching devices, and the third switch group comprises third switching devices. The first switching devices are coupled to respective output ends of the charging pile circuit groups so as to configure at least two idle charging pile circuit groups to be coupled either in series or in parallel to provide a first output. Each of the second switch group and the third switch group is configured to couple an input end of any of the charging terminals in series or in parallel to provide a second output to the charging pile circuit groups.
