The invention discloses a battery damp-heat early warning method and a vehicle. The method comprises the steps that a risk change cloud picture of a battery pack is generated based on historical characteristic parameters in different areas on the battery pack of a vehicle, and the risk change cloud picture is used for representing the parameter change condition of the characteristic parameters in a future time period; the thermophysical parameters of the battery pack are identified, identification parameters of the battery pack are obtained, and the thermophysical parameters are used for representing parameters obtained by conducting a thermophysical test on the battery pack; and carrying out damp-heat early warning on the risk change cloud atlas based on the identification parameters, and determining whether the battery pack has damp-heat risks or not. The technical problem that the damp heat early warning effect on the vehicle battery is poor in the related technology is solved.

    本发明公开了一种电池湿热预警方法和车辆。其中,该方法包括:基于车辆的电池包上不同区域中的历史特征参数,生成电池包的风险变化云图,其中,风险变化云图用于表征特征参数在未来时间段内的参数变化情况;对电池包的热物性参数进行辨识,得到电池包的辨识参数,其中,热物性参数用于表征对电池包进行热物性测试得到的参数;基于辨识参数对风险变化云图进行湿热预警,确定电池包是否存在湿热风险。本发明解决了相关技术中对车辆电池进行湿热预警的效果差的技术问题。
