The invention provides an energy conversion device and a vehicle, the energy conversion device comprises a reversible PWM rectifier and a motor coil, and the motor coil comprises a first winding unit,a second winding unit and a third winding unit which are respectively connected with the reversible PWM rectifier; an external alternating-current port and a battery form an alternating-current charging circuit or an alternating-current discharging circuit through the energy conversion device; wherein the first end, the second end and the third end of the alternating-current port are respectivelyconnected with the first winding unit, the second winding unit and the third winding unit in a one-to-one correspondence manner, the first end of the battery is connected with the first confluence end of the reversible PWM rectifier, and the second end of the battery is connected with the second confluence end of the reversible PWM rectifier. When the device is applied to the vehicle, the alternating-current charging and discharging circuits and the driving circuit can reuse the reversible PWM rectifier and the motor coil, and the problems that an existing overall control circuit comprising abattery charging circuit, a motor driving circuit and a heating circuit is complex in structure, low in integration level, large in size and high in cost are solved.
Description
technical field [0001] The application belongs to the field of electronic technology, and in particular relates to an energy conversion device and a vehicle thereof. Background technique [0002] With the continuous popularization of electric vehicles, more and more electric vehicles will enter society and families, bringing great convenience to people's travel. Relevant subsidy policies for the construction of charging stations in various places are also planned or even introduced. Both the quantity and the distribution range have been greatly improved. However, due to the limitation of the mileage of pure electric vehicles, vehicle users are very concerned about the problem that the vehicle breaks down due to the exhaustion of the power source. Although many vehicle manufacturers remind the vehicle driver of the remaining battery power information and low battery warning information through the vehicle instrument or other methods, it is inevitable that the remaining power...
