The invention relates to a charging system and a charging confirmation method. The charging system comprises a whole vehicle side controller; the positive electrode of the first diode is electrically connected to the charging pile; the auxiliary confirmation unit is electrically connected to the negative electrode of the first diode and the whole vehicle side controller; the auxiliary confirmation unit comprises at least one digital potentiometer, the digital potentiometer is provided with a communication interface and a resistance interface, and the communication interface is electrically connected to the whole vehicle side controller and used for receiving a resistance adjusting signal sent by the whole vehicle side controller; the resistor interface is electrically connected to the negative electrode of the first diode and the ground and is used for outputting target impedance adjusted according to the resistance adjusting signal. The target impedance can be rapidly set and switched according to different whole vehicles, so that the charging pile and the whole vehicle are rapidly matched, the diagnosis and detection time is shorter, and the response speed and the charging efficiency of the circuit are improved. As the digital potentiometer occupies small space and few interfaces, the area of a circuit board is reduced, the number of devices is reduced, and the digital potentiometer is simpler and easier to use.
本申请涉及一种充电系统及充电确认方法,该充电系统包括:整车侧控制器;第一二极管,第一二极管的正极电连接于充电桩;辅助确认单元,电连接于第一二极管的负极以及整车侧控制器;辅助确认单元包括至少一数字电位器,数字电位器上设有通信接口以及电阻接口,通信接口电连接于整车侧控制器,用于接收整车侧控制器发送的调阻信号;电阻接口分别电连接于第一二极管的负极和地,用于输出根据调阻信号调整后的目标阻抗。本申请能够根据整车的不同快速设置和切换目标阻抗,使得充电桩和整车快速匹配,诊断检测时间更短,提升了电路的响应速度和充电效率。由于数字电位器占用空间小,占用接口少,降低了电路板面积,减少了器件数量,更加简单易用。
