The invention discloses a vehicle power battery charging method and a charging pile. The method comprises the steps that target loop connection is established between a charging pile and a power battery of a target vehicle, and a target loop comprises a charging loop and a temperature management loop; exchanging the first cooling liquid preprocessed to the target temperature in the charging pile with the second cooling liquid in the power battery through a temperature management loop; and after the exchange is completed, the power battery is charged through the charging loop. The technical problems that in the related technology, the charging efficiency of a charging pile on a vehicle power battery is low, and user requirements are difficult to meet are solved.

    本申请公开了一种车辆动力电池充电方法及充电桩。其中,该方法包括:充电桩与目标车辆的动力电池建立目标回路连接,其中,目标回路包括:充电回路和温度管理回路;通过温度管理回路将充电桩中预处理至目标温度的第一冷却液与动力电池中的第二冷却液进行交换;交换完成后,通过充电回路对动力电池进行充电。本申请解决了相关技术中充电桩对车辆动力电池充电效率较慢,难以满足用户需求的技术问题。
