摘　　要：随着新能源车型的快速迭代,零件不断变更,车型开发周期缩短,导致车型中存在亏电现象。此现象不仅影响影响车型的用户口碑,还使售后排查困难。文章针对纯电动汽车亏电进行了原因分析,提供汽车亏电时排查的方向,并通过平台预警,降低车辆亏电率,提升用户用车体验。With the rapid iteration of new energy vehicles,parts are constantly changing,and the development cycle of vehicle models is shortened,resulting in a power deficit in vehicle models.This phenomenon not only affects the reputation of users of the model,but also makes after-sales investigation difficult.This article analyzes the reasons for the power loss of pure electric vehicles,provides directions for investigation when the car is losing power,and uses platform warnings to reduce the rate of vehicle power loss and improve the user's car experience.
