The invention provides an energy conversion device and a vehicle, and the energy conversion device comprises a motor controller, a bus capacitor, a first switch module, a motor, a second switch module and a third switch module. Through the control of the on or off of the first switch module, the second switch module and the third switch module, the energy conversion device can enter a motor driving mode, a battery pack self-heating mode and a battery pack electricity-keeping self-heating mode; in the battery pack self-heating mode, the process of discharging the bus capacitor by the battery pack in the battery pack self-heating loop and the process of charging the battery pack by the bus capacitor can be alternately carried out, so that the temperature rise of the battery pack is realized; in the battery pack power-keeping self-heating mode, when a battery pack is in the battery pack heating process, the external power supply equipment supplies power to the battery pack self-heating loop, so the electric quantity of the battery pack is maintained, and the problem that the electric quantity is reduced when the battery pack outputs electric energy for self-heating is avoided.

    本申请提供一种能量转换装置及车辆,能量转换装置包括电机控制器、母线电容、第一开关模块、电机、第二开关模块以及第三开关模块,通过控制第一开关模块、第二开关模块以及第三开关模块的导通或者关断,可以使能量转换装置进入电机驱动模式、电池包自加热模式以及电池包保电自加热模式,在电池包自加热模式下可以使电池包自加热回路中的电池包对母线电容的放电过程与母线电容对电池包的充电过程交替进行进而实现电池包的升温,在电池包保电自加热模式下,当电池包进行加热的过程中,外部的供电设备对电池包自加热回路进行供电,维持了电池包的电量,避免了电池包输出电能进行自加热时导致的电量降低的问题。
