The invention discloses an electric vehicle charging framework compatible with two charging voltages of 400V and 800V. The electric vehicle charging framework comprises a standard charging port, a vehicle-mounted charging control module and a charging system, the charging system comprises two groups of battery modules with voltage of 400V, a single-pole single-throw switch relay, a single-pole double-throw switch relay and two main fuses. The vehicle-mounted charging control module is used for controlling and driving switches of the single-pole single-throw switch relay and the single-pole double-throw switch relay and controlling and driving a main circuit breaker for charging; the invention provides an electric vehicle charging framework compatible with two charging voltages of 400V and 800V by changing the series-parallel connection relation of battery modules and a charging method thereof.
本发明公开了兼容400V和800V两种充电电压的电动车充电架构,包括标准充电口,车载充电控制模块和充电系统;所述充电系统包括两组电压为400V的电池模组,一个单刀单掷开关继电器,一个单刀双掷开关继电器和两个主保险丝;所述车载充电控制模块用于控制和驱动单刀单掷开关继电器和单刀双掷开关继电器的开关,以及控制和驱动充电的主断路器;提供了一种通过改变电池模组的串并联关系来支持兼容400V和800V两种充电电压的电动车充电架构及其充电方法。
