The embodiment of the invention provides a control method and system for charging preheating of an electric vehicle. The control method comprises the steps that the battery temperature is obtained and compared with a preheating temperature threshold value and a heating temperature threshold value; when the battery temperature is smaller than a preheating temperature threshold value, entering a battery preheating mode; when the battery temperature is greater than a preheating temperature threshold value and less than a heating temperature threshold value, entering a charging heating mode; and when the battery temperature is greater than a heating temperature threshold value, entering a charging mode. The technical problem that in the prior art, a power battery is weak in charging capacity or does not have charging capacity in a low-temperature environment is solved.

    本发明的实施例提供了一种电动汽车充电预加热的控制方法及系统,获取电池温度并将所述电池温度分别与预加热温度阈值和加热温度阈值相比较;当所述电池温度小于预加热温度阈值时,则进入电池预加热模式;当所述电池温度大于预加热温度阈值且小于加热温度阈值时,则进入充电加热模式;当所述电池温度大于加热温度阈值时,则进入充电模式。解决了现有技术中存在的动力电池在低温环境下充电能力很弱或没有充电能力的技术问题。
