The invention relates to an energy conversion device applied to a vehicle-mounted power battery, a control method of the energy conversion device and a vehicle. The device comprises a voltage adjusting module used for reducing the output voltage of the power battery and then outputting the voltage from the second end of the voltage adjusting module; the input end of the first voltage conversion module is connected with the second end of the voltage adjusting module, and the first voltage conversion module is used for converting the direct current into alternating current and supplying the alternating current to a first motor; the input end of the second voltage conversion module is connected with the power battery or the second end of the voltage adjusting module, and the second voltage conversion module is used for converting the direct current into alternating current and supplying the alternating current to a second motor; and the controller is configured to control the voltage adjusting module, the first voltage conversion module and the second voltage conversion module to enable the power battery to supply power as required if it is judged that the power battery needs to supply power to the first motor and/or the second motor. According to the scheme, driving of motors of different voltage platforms is realized.
