Claim 13:
14. The power system comprising according to claim 13, wherein the DC/DC conversion module further comprises:
a first input/output end connected in parallel to the bus capacitor, wherein the first input/unit end is used as an input end of the DC/DC conversion module when the bridge arm conversion module converts the alternating current input voltage supplied by the alternating current charging interface to form the bus voltage of the bus capacitor, and used as an output end of the DC/DC conversion module when the bridge arm conversion module drives the motor based on the bus voltage of the bus capacitor;
a second input/output end configured to connect the traction battery via a fuse, wherein the second input/output end is used as an input end of the DC/DC conversion module when the DC/DC conversion module converts the traction battery voltage to form the bus voltage and used as an output end of the DC/DC conversion module when the DC/DC conversion module converts the bus voltage of the bus capacitor to charge the traction battery.
