The embodiment of the invention discloses an electric vehicle battery aging identification method and device, terminal equipment and a computer readable storage medium. The method comprises the stepsof obtaining charging current data of an electric vehicle; determining whether the charging current data has preset charging curve characteristics including that the step number is greater than or equal to a first preset number threshold, the amplitude of a single step is smaller than a preset current threshold, the length of the single step is larger than or equal to a preset length threshold, the current difference of the descending section of each step is smaller than or equal to the preset percentage of the current of the stable section, and the current value of the end point of each stepis larger than that of the initial point of the trickle section; and if the charging current data has the preset charging curve characteristics, judging that the battery of the electric vehicle is aged. According to the embodiment of the invention, the method achieves the recognition of the aging phenomenon of the electric vehicle battery, timely knows whether the electric vehicle battery is agedor not, reduces the potential safety hazards in a charging process, and improves the safety of the electric vehicle charging process.

    本申请实施例公开了一种电动车电池老化识别方法、装置、终端设备及计算机可读存储介质,方法包括:获取电动车的充电电流数据;确定充电电流数据是否具备预设充电曲线特征,预设充电曲线特征为包括阶梯数量大于或等于第一预设数量阈值、单个阶梯幅度小于预设电流阈值、单个阶梯的长度大于或等于预设长度阈值、每个阶梯的下降段电流差小于或等于平稳段电流的预设百分比和每个阶梯的结束点的电流值大于涓流段起始点的电流值的特征;若充电电流数据具备预设充电曲线特征,则判定电动车的电池出现老化现象。本申请实施例实现了对电动车电池老化现象的识别,及时得知出电动车电池是否老化,降低充电过程的安全隐患,提高了电动车充电过程的安全性。
