According to the hybrid electric vehicle battery heating control method and system, the battery heating target temperature is divided into a plurality of different gradients according to the remaining electric quantity of a battery, different heating rates are adopted for different gradients, meanwhile, the heating rates are further corrected in combination with other state information of a current vehicle, and the battery heating target temperature is obtained. In other words, the relatively high heating rate is adopted for relatively low residual electric quantity, and the relatively low heating rate is adopted for relatively high residual electric quantity, so that the effect of finely controlling the heating rate of the battery is achieved, the waste of energy consumption in a low-temperature environment is reduced, and the endurance mileage is improved.
一种混合动力汽车电池加热控制方法及控制系统,电池加热控制方法根据电池的剩余电量,将电池加热目标温度分为多个不同的梯度,不同的梯度采用不同的加热速率,同时结合当前车辆的其他状态信息,进一步对加热速率进行修正,即较低的剩余电量采取较高的加热速率,较高的剩余电量采取较低的加热速率,从而达到精细化控制电池加热速率的效果,降低低温环境下能耗的浪费,提升续航里程。
