The invention provides an energy conversion system and an electric vehicle. The energy conversion system comprises a controller, a first charging port, a first switch tube combination circuit and a second switch tube combination circuit. The first switch tube combination circuit is used for connecting the first charging port and the power battery, and the second switch tube combination circuit is used for connecting the power battery. The controller is used for controlling an upper switch tube and a lower switch tube in the first switch tube combination circuit and the second switch tube combination circuit to be switched on or switched off, so that current output from the first charging port flows to the power battery through a winding in the first switch tube combination circuit and the switched-on switch tube; and the winding in the second switch tube combination circuit alternately charges and discharges the power battery, so that the self-heating charging of the power battery is realized. According to the invention, the charging temperature of the power battery can be improved, and the charging efficiency of the electric vehicle is improved.

    本申请提供一种能量转换系统及电动车辆。其中,能量转换系统包括控制器、第一充电口、第一开关管组合电路和第二开关管组合电路。第一开关管组合电路用于连接第一充电口和动力电池,第二开关管组合电路用于连接动力电池。控制器用于控制第一开关管组合电路和第二开关管组合电路中的上开关管和下开关管导通或关断,使得从第一充电口输出的电流经过第一开关管组合电路中的绕组和导通的开关管流向动力电池,且使得第二开关管组合电路中的绕组对动力电池进行交替充放电,以使动力电池实现自加热充电。采用本申请,能够提高动力电池的充电温度,提高了电动车辆的充电效率。
