The invention provides a battery heat preservation control method and system based on a power grid, which belong to the field of vehicle control. The battery heat preservation control method comprisesthe steps that whether the temperature of a battery pack of a vehicle is lower than a first preset value or not is judged after the vehicle is charged by a charging pile and a vehicle-mounted chargerof the vehicle is in an inserted state with the charging pile; when the temperature of the battery pack of the vehicle is lower than the first preset value, the vehicle-mounted charger is controlledto send a charging request to the charging pile, and meanwhile, a battery pack power supply switch is controlled to be switched off, so that a thermal management system of the vehicle obtains energy of the charging pile through the vehicle-mounted charger and is used for heating the battery pack; and when the temperature of the battery pack of the vehicle is higher than a second preset value, thevehicle-mounted charger is controlled to send a charging stopping request to the charging pile, so that the charging pile stops providing energy, and the second preset value is higher than the first preset value. According to the battery heat preservation control method and system, the drivability of the vehicle can be ensured, and the endurance mileage of the whole vehicle is reduced.
本发明提供了一种基于电网的电池保温控制方法及控制系统,属于车辆控制领域。该电池保温控制方法包括:在车辆完成充电桩充电后且车辆的车载充电机与充电桩处于插接状态时,判断车辆的电池包的温度是否低于第一预设值;当车辆的电池包的温度低于第一预设值时控制车载充电机向充电桩发送充电请求,同时控制电池包供电开关断开,以使得车辆的热管理系统通过车载充电机获取充电桩的能量并用于加热电池包;当车辆的电池包的温度高于第二预设值时控制车载充电机向充电桩发送停止充电请求,以使得充电桩停止提供能量,其中,第二预设值高于第一预设值。本发明的电池保温控制方法及控制系统能够确保车辆的驾驶性能并减少整车的续航里程下降。
