This application proposes an energy conversion device and a vehicle. The energy conversion device includes a motor coil of a motor, a bridge arm converter, a bus capacitor connected in parallel with the bridge arm converter, and a controller connected to the bridge arm converter. Drive power and heating power of the motor coil, control the bridge arm converter to make the external power supply connected to the external charging and discharging port or the electric energy of the external battery flow to the driving and heating circuit, and adjust the current of the driving and heating circuit to make the external power supply or the external battery The battery drives the motor to work while the motor coil consumes power to generate heat. The application only needs to control the bridge arm converter and then adjust the external power supply or the current flowing from the external battery to the driving and heating circuit, so that the external power supply or When the external battery drives the motor to work, the motor coil consumes electricity to generate heat, which solves the problems in the prior art that the motor control system has a complex overall structure, low integration, large volume and high cost.
Description
technical field [0001] The present application relates to the technical field of vehicles, in particular to an energy conversion device and a vehicle. Background technique [0002] In recent years, with the continuous development of electric vehicle technology, the market's acceptance of electric vehicles has continued to increase, and battery charging and motor drive, as the core technologies in electric vehicles, have received widespread attention. At present, the battery heating circuit and the motor drive circuit in the existing electric vehicles on the market are separated. The heating circuit is used to heat the battery of the electric vehicle, and the motor drive circuit is used to drive the motor of the electric vehicle. intervene independently of each other. [0003] However, although two circuits can be used to complete the heating and motor driving process of electric vehicles, since the two circuits in the above method do not interfere with each other and are in...
