The invention provides an electric vehicle cooling liquid filling method and system, and relates to the technical field of electric vehicle cooling liquid filling, and the electric vehicle cooling liquid filling method comprises the steps that cooling liquid level information and a whole vehicle slope signal are obtained, and whether the cooling liquid is lost or not is judged; when it is judged that the cooling liquid needs to be injected, the whole vehicle is adjusted to normally increase high pressure and is in a P gear, a cooling liquid injection request is triggered to the heat management control module, and after the heat management control module receives the cooling liquid injection request, cooling liquid injection is controlled to run; and an operation cycle is executed, whether the trigger request for filling the cooling liquid is continuous or not is obtained in real time, if the trigger request for filling the cooling liquid is not closed, the operation cycle for filling the cooling liquid is repeated, and filling and supplementing of the cooling liquid are achieved.

    本公开提供了一种电动汽车冷却液加注方法及系统,涉及电动汽车冷却液加注技术领域,包括:获取冷却液液位信息以及整车坡度信号,判断冷却液是否发生缺失;当判断需要加注冷却液时,调整整车正常上高压且处于P档,触发冷却液加注请求至热管理控制模块,当热管理控制模块接收到冷却液加注请求后控制运行冷却液加注;执行一个运行循环,实时获取冷却液加注的触发请求是否持续,若冷却液加注触发请求未关闭,则重复加注冷却液运行循环,实现冷却液的加注以及补加。
