Power supply system and electric excavator
The invention discloses a power supply system and an electric excavator. The power supply system comprises an AC power supply input module, a DC power supply input module, an AC power supply conversion module, a DC power supply conversion module, a power distribution module and a power storage battery. The alternating current power supply input module is connected with an external alternating current power supply and connects the external alternating current power supply to the alternating current power supply conversion module; the AC power supply conversion module converts an external AC power supply into a DC power supply. The direct-current power supply input module is connected with an external direct-current power supply, and the direct-current power supply input module connects the external direct-current power supply to the direct-current power supply conversion module and the power distribution module; the direct-current power supply conversion module converts an external direct-current power supply and charges the power storage battery; and the power distribution module outputs a power supply suitable for the power storage battery and the electric equipment and supplies power to the power storage battery and the electric equipment. The power supply system supplies power by accessing an external direct-current power supply and an external alternating-current power supply, so that the working efficiency of the power supply system is improved.
