The embodiment of the invention provides a direct current charging control system and method for an electric vehicle. The direct current charging control system comprises a cooling assembly, a battery management system, a temperature sensor and a controller. The cooling assembly is suitable for cooling the charging socket of the electric vehicle, and the cooling intensity of the cooling assembly can be adjusted; the battery management system interacts with the charging pile to obtain current information of the charging pile; the temperature sensor is arranged in the charging socket to obtain the temperature of the charging socket; the controller is in signal connection with the temperature sensor and the battery management system, and the controller is suitable for adjusting the cooling intensity of the cooling assembly according to the current information and the temperature of the charging socket. Therefore, on one hand, the charging socket can be prevented from being overheated, and the charging safety is improved; and on the other hand, the cooling intensity of the cooling assembly is more reasonable, so that the power consumption of the cooling assembly is more reasonable, and the energy consumption of the direct current charging control system can be effectively reduced.
根据本发明实施例的用于电动车辆的直流充电控制系统以及控制方法,所述直流充电控制系统包括:冷却组件、电池管理系统、温度传感器以及控制器;冷却组件适于对电动车辆的充电插座进行冷却,且冷却组件的冷却强度能够被调节;电池管理系统与充电桩交互以获取充电桩的电流信息;温度传感器设置在充电插座内以获取充电插座的温度;控制器与温度传感器、电池管理系统信号连接,控制器适于根据电流信息、充电插座的温度调整冷却组件的冷却强度。由此,一方面,可以避免充电插座过热,提高充电安全性;另一方面,使冷却组件的冷却强度更加合理,以使冷却组件的功耗更加合理,可以有效地降低直流充电控制系统的能耗。
