The invention relates to the technical field of vehicles, and discloses a power battery safety early warning method and system, a vehicle and a medium, and the method comprises the steps: obtaining the battery safety data of a target vehicle, and determining the working condition of the vehicle based on the battery safety data; based on the battery safety data, battery heat production and actual temperature rise of the vehicle working condition are obtained; a corresponding temperature rise threshold value under the vehicle working condition is determined based on the battery heat production amount; judging whether the battery is abnormal or not based on the temperature rise threshold value and the actual temperature rise; and when the battery is abnormal, generating early warning information, and performing battery safety early warning processing based on the early warning information. According to the method, the error caused by the influence of the actual vehicle working condition on the battery temperature can be considered, the dynamic temperature rise threshold values under different vehicle working conditions are increased, the safety early warning of the power battery can be realized only by judging the temperature rise threshold values and the actual temperature rise, the early warning process can be simplified, the early warning precision and effect are improved, and the safety of the power battery is improved. And a favorable guarantee is provided for safe use of different types of electric automobiles.
本发明涉及车辆技术领域,公开了一种动力电池安全预警方法、系统、车辆及介质,方法包括:获取目标车辆的电池安全数据,并基于电池安全数据确定车辆工况;基于电池安全数据获取车辆工况的电池产热量和实际温升;基于电池产热量确定在车辆工况下对应的温升阈值;基于温升阈值和实际温升判断电池是否存在异常;在电池存在异常时,生成预警信息,并基于预警信息进行电池安全预警处理。本发明能够考虑到实车工况对电池温度影响导致的误差,增加了不同车辆工况下的动态温升阈值,仅需通过对温升阈值和实际温升的判定即可实现动力电池的安全预警,可以简化预警流程,提高了预警的精度和效果,为不同类型电动汽车的安全使用提供了有利保障。
