The invention provides a charging device with double battery packs and an electric vehicle. The charging device is characterized in that an AC input filter circuit obtains filtered AC voltage after filtering processing; an APFC conversion circuit rectifies the filtered AC voltage to obtain a rectified first DC voltage; the rectified first DC voltage is boosted to obtain a rectified second DC voltage; a DC/DC conversion circuit inverts the rectified second DC voltage to obtain a DC voltage in a square wave form; voltage reduction and rectification are performed on the square-wave DC voltage to obtain a third DC voltage; a shunt circuit sends charging request information to a control circuit when detecting the battery voltage of a first battery pack and/or the battery voltage of a second battery pack within a preset time; and the control circuit controls the third DC voltage to charge the first battery pack and/or the second battery pack according to the charging request information, so that the battery voltage of the first battery pack and/or the battery voltage of the second battery pack are/is in a saturated state.

    本发明提供了双电池包的充电装置和电动车,包括:AC输入滤波电路通过滤波处理后得到滤波后的交流电压;APFC变换电路将滤波后的交流电压整流得到整流后的第一直流电压;将整流后的第一直流电压进行升压得到整流后的第二直流电压;DC/DC变换电路将整流后的第二直流电压进行逆变得到方波形式的直流电压;将方波形式的直流电压进行降压和整流得到第三直流电压;分流电路在预设时间内检测到第一组电池包的电池电压和/或第二组电池包的电池电压的情况下,向控制电路发送充电请求信息;控制电路根据充电请求信息控制第三直流电压充电给第一组电池包和/或第二组电池包,使第一组电池包的电池电压和/或第二组电池包的电池电压为饱和状态。
