Battery thermal management

The invention relates to battery thermal management. A method for managing thermal energy of a vehicle having a battery and an electric propulsion system is provided. The system monitors a current battery temperature, after the vehicle is connected to an outside power source at a plug time, and determines an outside air temperature. The system predicts a cabin heating temperature for a subsequentdrive cycle. The subsequent drive cycle occurs when the vehicle is no longer connected to the outside power source. If the predicted cabin heating temperature is greater than the outside air temperature, the system heats the battery to a thermal storage temperature that is greater than a target operating temperature of the battery. Therefore, thermal energy is stored within the battery, and may betransferred to heat the cabin. 本发明涉及电池热管理。提供了用于管理具有电池和电力推进系统的车辆的热能的方法。车辆在插电时间连接到外部电源后，系统监测当前电池温度，并确定外部空气温度。系统预测后续驾驶循环的车厢加热温度。当车辆不再与外部电源连接时，发生后续驾驶循环。如果预测的车厢加热温度高于外部空气温度，则系统将电池加热到高于电池的目标操作温度的蓄热温度。因此，热能储存在电池内，并且可以被传递以加热车厢。
