The system comprises an input connector and one or more boosting electrical elements, one end of the input connector is used for being electrically connected with an external power source, the other end of the input connector is electrically connected with an electric drive assembly element of a vehicle electric drive assembly through the boosting electrical elements, and a boosting circuit is formed; the output end of the boosting circuit is used for being electrically connected with a battery, and the boosting electrical element is contained in a driving assembly shell of the vehicle electric driving assembly. According to the vehicle direct-current boost charging system, the boost electrical element and the electric drive assembly element of the vehicle electric drive assembly form the boost circuit, so that an external power supply connected to the input connector is boosted through the boost circuit and then charges the battery. As the boosting electrical element is accommodated in the driving assembly shell of the vehicle electric driving assembly, a boosting box does not need to be additionally arranged, the vehicle direct current boosting charging system can be deeply integrated in the electric driving assembly, the design is simplified, the size is reduced, and the cost is reduced.
本发明公开一种车辆直流升压充电系统及车辆,系统包括:输入接插件以及一个或多个升压电气元件,输入接插件一端用于与外部电源电连接,另一端通过升压电气元件与车辆电驱动总成的电驱总成元件电连接,形成升压电路,升压电路的输出端用于与电池电连接,升压电气元件容置在车辆电驱动总成的驱动总成壳体内。本发明的车辆直流升压充电系统,其升压电气元件与车辆电驱动总成的电驱总成元件形成升压电路,从而将输入接插件接入的外部电源,通过升压电路升压后,为电池充电。由于升压电气元件容置在车辆电驱总成的驱动总成壳体内,因此无需额外设置升压盒子,车辆直流升压充电系统能够深度集成于电驱动总成内部,简化设计,减少体积,并降低成本。
