The invention relates to the technical field of vehicles, in particular to a battery abnormality determining method and device and a battery charging remaining time determining method and device. Thebattery abnormality determining method comprises the steps of obtaining vehicle state data of at least two adjacent moments including a current moment, inputting the obtained vehicle state data into atrained battery temperature parameter estimation model to obtain a predicted temperature parameter of a battery at the current moment, and determining whether the battery is abnormal or not based onthe predicted temperature parameter of the battery and the actual temperature parameter of the battery. According to the method, the temperature parameter is predicted by adopting the vehicle state data at multiple adjacent moments which can influence the temperature of the battery, so that the accuracy of temperature parameter prediction can be improved, and the reliability of judging whether thebattery is abnormal or not can be improved.

    本申请涉及车辆技术领域,尤其涉及一种电池异常、电池充电剩余时间的确定方法及装置。其中,电池异常的确定方法包括获取包括当前时刻的至少两个相邻时刻的车辆状态数据,并将获取的车辆状态数据输入训练好的电池温度参数预估模型中,可以得到当前时刻的电池预测温度参数,进而,基于电池预测温度参数和电池实际温度参数,可以确定电池是否出现异常。通过采用会对电池温度产生影响的多个相邻时刻的车辆状态数据进行温度参数的预测,可以提高预测温度参数的准确性,进而,可以提高判断电池是否异常的可靠性。
