The invention relates to an electric vehicle high-voltage safety control method and device and a vehicle, which belong to the field of vehicles. The electric vehicle high-voltage safety control methodcomprises the following steps that the vehicle speed information is obtained; when the vehicle speed information is not greater than a threshold value, charging port cover state information is obtained; when the state of the charging port cover is an open state, the electric vehicle is controlled to be in a non-high-voltage state, that is, when finger touch safety possibly occurs, the electric vehicle is controlled to be in the non-high-voltage state to avoid finger touch safety accidents, that is, the positive electrode of the battery pack and the positive electrode of the load in the electric vehicle are controlled to be disconnected, and/or the negative electrode of the battery pack and the negative electrode of the load are controlled to be disconnected.
本公开涉及一种电动车高压安全控制方法、装置及车辆,属于车辆领域,其中一种电动车高压安全控制方法包括如下步骤:获取车速信息;在所述车速信息不大于阈值时,获取充电口盖状态信息;在所述充电口盖的状态为打开状态时,控制电动车处于非高压状态,即在可能出现指触安全时,控制电动车处于非高压状态避免出现指触安全事故,也即控制电动车中的电池包的正极与负载的正极处于断开状态,和/或电池包的负极与负载的负极处于断开状态。
