CHARGING PILE APPARATUS AND SYSTEM, AND CHARGING METHOD

摘要

A charging pile apparatus and system, and a charging method. The apparatus comprises a power supply unit (101), a direct-current charging unit (102), and a state monitoring unit (103). The power supply unit (101) is connected to the direct-current charging unit (102) to supply power to the direct-current charging unit (102). The state monitoring unit (103) is connected to the power supply unit (101) and the direct-current charging unit (102). The power supply unit (101) is used for receiving external power supply, and processing an input voltage and outputting a stable direct current. The direct-current charging unit (102) is used for receiving the direct current output by the power supply unit (101) and charging an externally-connected storage battery. The state monitoring unit (103) is used for acquiring state information of the power supply unit (101) and the direct-current charging unit (102), and monitoring a charging process of the direct-current charging unit (102). By means of the charging pile apparatus, the externally-connected storage battery can be directly charged.
