摘要： 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.
