The invention provides a charging system and an electric vehicle, the charging system comprises a motor controller MCU and a first inductor, a first bridge arm in the MCU and the first inductor form a voltage conversion circuit, when the power supply voltage is smaller than the minimum charging voltage of a power battery, the MCU can carry out boost conversion on the power supply voltage through the voltage conversion circuit, and then the power battery is charged. The power supply voltage after boosting conversion is used as first output voltage to be output to the power battery, and the first output voltage is not less than the minimum charging voltage. While the charging system is utilized to carry out voltage reduction conversion on the power supply voltage, the occupied space and the cost of the charging system are reduced.
本申请提供一种充电系统及电动汽车,该充电系统包括电机控制器MCU和第一电感,MCU中的第一桥臂和第一电感构成电压转换电路,MCU可以在电源电压小于动力电池的最小充电电压时,通过电压转换电路对电源电压进行升压转换,并将升压转换后的电源电压作为第一输出电压输出给动力电池,该第一输出电压不小于最小充电电压。本申请可以在利用充电系统对电源电压进行降压转换的同时,降低充电系统所占用的空间和成本。
