The invention provides a vehicle, an energy conversion device and a charging method thereof.A switch module and a second switch module are arranged, the second switch module is arranged between a power battery and a voltage transformation module, and when the first switch module is turned on, the power battery, the first switch module, an energy storage module and an external power module form a first charging loop; and when the second switch module is switched on, the power battery, the second switch module, the voltage transformation module, the energy storage module and the external power supply module form a second charging loop. According to the technical scheme, when the high-voltage power supply platform direct-current charging pile is connected, direct-current charging can be carried out through the first charging loop, the charging speed of the power battery is increased, and when the low-voltage power supply platform direct-current charging pile is connected, boosting charging can be carried out through the second charging loop; the problem that in the prior art, a low-voltage power supply platform direct-current charging pile cannot fully charge a power battery or cannot charge the power battery is solved.

    本申请提供一种车辆、能量转换装置及其充电方法,通过设置一开关模块和第二开关模块,并将第二开关模块设置在动力电池与变压模块之间,当第一开关模块导通时,动力电池、第一开关模块、储能模块以及外部电源模块构成第一充电回路,当第二开关模块导通时,动力电池、第二开关模块、变压模块、储能模块以及外部电源模块构成第二充电回路。本申请技术方案当连通高电压供电平台直流充电桩时,可以通过第一充电回路进行直流充电,提升了动力电池的充电速度,当连通低电压供电平台直流充电桩时,可以通过第二充电回路进行升压充电,解决了现有技术中低电压供电平台直流充电桩对动力电池充电充不满或是不能充电的问题。
