Abstract: An energy conversion apparatus and a vehicle are provided. The energy conversion apparatus includes a motor coil of a motor (101), a bridge arm converter (102), a bus capacitor (103) connected to the bridge arm converter (102) in parallel, and a controller (104) connected to the bridge arm converter (102). When the energy conversion apparatus is connected to an external power supply, according to to-be-driven power of the motor and to-be-charged power of an external battery (105), the controller (104) controls the bridge arm converter (102) to cause electrical energy of the external power supply to flow to a drive-charging circuit, and adjusts a current of the drive-charging circuit, to cause the external power supply to drive the motor to output drive power and charge the external battery (105) at the same time.
