The invention discloses a power battery health assessment method and device based on an electric vehicle charging pile management platform, equipment and a medium. The method comprises the steps of: using a charging pile for obtaining a target temperature when the charging charge quantity of a power battery of a target electric vehicle reaches a preset charging state in each charging process; whenthe power battery reaches a preset charging stopping condition in each charging process, obtaining a target charging charge quantity; judging whether the target temperature is within a preset range or not; if yes, fitting a charging model of the power battery, and determining a predicted charging charge quantity of the power battery at the target number of times according to the charging model; screening the charging charge quantity meeting a preset screening condition from the target charging charge quantity to obtain a screening charge quantity group, and obtaining a charge average value ofthe screening charge quantity group; and evaluating the health condition of the power battery according to the predicted charge quantity and the charge average value. Obviously, the management experience of an operator in the management process of the electric vehicle can be remarkably improved.

    本申请公开了的一种基于电动汽车充电桩管理平台的动力电池健康评估方法、装置、设备及介质,包括:利用充电桩获取目标电动汽车的动力电池在每次充电过程中充电电荷量达到预设充电状态时的目标温度;当动力电池在每次充电过程中达到预设中止充电条件时,获取目标充电电荷量;并判断目标温度是否在预设范围之内;若是,则拟合动力电池的充电模型,并根据充电模型确定动力电池在第目标次数时的预测充电电荷量;从目标充电电荷量中筛选符合预设筛选条件的充电电荷量,得到筛选电荷量组,并获取筛选电荷量组的电荷平均值;根据预测充电电荷量和电荷平均值评估动力电池的健康状况。显然,这样可以显著提高运营商在对电动汽车进行管理过程中的管理体验。
