The invention relates to the technical field of electric vehicle batteries, in particular to an electric vehicle power battery monitoring method and device, a server and a medium, and the method comprises the steps: receiving charging data and discharging data collected by a target vehicle in a preset state of charge (SOC) interval; matching a battery attenuation model obtained by pre-training according to the identity label of the target vehicle, inputting the charging data and the discharging data into the battery attenuation model, and outputting the actual attenuation degree of the power battery in the target vehicle; if the actual attenuation degree is smaller than a preset abnormal threshold value, it is judged that the power battery is in a preset abnormal state, the power battery of the target vehicle is generated for early warning prompt, and otherwise, it is judged that the power battery of the target vehicle is in a preset normal state. Therefore, the problems that a user cannot timely and accurately master the attenuation condition of the battery, the efficiency is extremely low, time and cost are wasted, the vehicle use safety of the user is reduced, and the use experience of the user is reduced in the related technology are solved.

    本申请涉及电动汽车电池技术领域,特别涉及一种电动汽车的动力电池监控方法、装置、服务器及介质,其中,包括:接收目标车辆在预设荷电状态SOC区间采集的充电数据和放电数据;根据目标车辆的身份标识匹配预先训练得到的电池衰减模型,将充电数据和放电数据输入电池衰减模型,输出目标车辆中动力电池的实际衰减度;若实际衰减度小于预设异常阈值,则判定动力电池处于预设异常状态,并生成目标车辆的动力电池进行预警提示,否则判定目标车辆的动力电池处于预设正常状态。由此,解决了相关技术中用户无法及时、准确掌握电池衰减状况,效率极低且浪费时间和成本,降低用户的用车安全,降低用户使用体验等问题。
