The invention relates to the technical field of automobile detection, and discloses a safety early warning method and system for the whole charging and discharging process of an electric automobile, and the method comprises the steps: collecting the image data of a battery pack when the remaining electric quantity of the electric automobile is lower than a preset threshold value, and determining the appearance detection evaluation value of the battery pack; charging the battery pack, and detecting charging data to determine a charging detection evaluation value of the battery pack; after the battery pack is charged, collecting discharge data to determine a discharge detection evaluation value of the battery pack; obtaining a final detection score P based on the appearance detection evaluation value, the charging detection evaluation value and the discharging detection evaluation value, and determining the risk level of the battery pack; and after determining that the risk level of the battery pack is Mi, collecting the temperature of the environment where the electric vehicle is located, judging whether the risk level is adjusted or not, obtaining the final risk level, and carrying out safety early warning. The comprehensiveness, accuracy and practicability of the electric vehicle safety early warning system are improved, and potential safety risks are effectively reduced.

    本发明涉及汽车检测技术领域,公开了一种电动汽车充放电全过程安全预警方法及系统,该方法包括:当电动汽车剩余电量低于预设阈值时,采集电池包的图像数据确定电池包的外观检测评价值;对电池包进行充电,检测充电数据确定电池包的充电检测评价值;当电池包充电完成后,采集放电数据确定电池包的放电检测评价值;基于外观检测评价值、充电检测评价值与放电检测评价值获得最终检测评分P确定电池包的风险等级;在确定电池包的风险等级为Mi后,采集电动汽车所处的环境温度并判断是否对风险等级进行调整,获取最终风险等级并进行安全预警。本发明提高了电动汽车安全预警系统的全面性、准确性和实用性,有效降低了潜在的安全风险。
