The invention discloses a control method, device and equipment of a fast charging contactor. A fast charging positive contactor is arranged on the positive electrode of a fast charging loop, and a fast charging negative contactor is arranged on the negative electrode of the fast charging loop; and the quick charging positive contactor and the quick charging negative contactor are controlled to be switched off or switched on according to the charging state of the whole vehicle or the state of a charging pile, so that the quick charging loop is controlled to be switched on or switched off. The positive electrode and the negative electrode of the quick charging loop can be controlled to be in an open state by controlling the quick charging positive contactor and the quick charging negative contactor to be opened and closed, it is guaranteed that when the quick charging loop has an insulation problem, the electric leakage risk cannot be generated, and the charging safety of the electric vehicle is effectively improved.
本申请公开了一种快充接触器的控制方法、装置和设备,通过在快充回路的正极设置快充正接触器,在所述快充回路的负极设置快充负接触器;根据整车的充电状态或充电桩状态控制所述快充正接触器和所述快充负接触器断开或闭合,以控制所述快充回路导通或断开。通过控制快充正接触器和快充负接触器断开和闭合能够控制快充回路的正极和负极都处于断开状态,保证了当快充回路出现绝缘问题时,也不会产生漏电风险,有效的提高了电动汽车充电的安全性。
