The invention provides a charging time prediction method, and the method comprises the steps: obtaining the voltage of a battery pack, the state of charge of a single body, the maximum voltage of the single body, and the maximum temperature of the single body, and determining the limiting current of a charging pile according to the voltage of the battery pack and the preset power of the charging pile; the method comprises the following steps: determining a request current of a vehicle according to a single charge state, a single maximum voltage and a single maximum temperature, then determining a charging current according to a limiting current of a charging pile and the request current of the vehicle, predicting single voltages of a plurality of single bodies in a charged battery pack based on a Thevenin model, and when the single maximum voltage after charging meets a preset condition, determining the charging current of the vehicle. And obtaining the charging time. Therefore, the charging time prediction method considering various conditions is provided.

    本申请提供了一种充电时间预测方法,该方法通过获取车辆所发送的电池包电压、单体荷电状态、单体最高电压和单体最高温度,然后根据电池包电压与充电桩的预设功率确定充电桩的限制电流,根据单体荷电状态、单体最高电压和单体最高温度,确定车辆的请求电流,然后根据充电桩的限制电流和车辆的请求电流确定充电电流,基于戴维南模型预测充电后电池包中多个单体的单体电压,当充电后的单体最高电压满足预设条件时,获得充电时间。由此,提供了一种考虑多种条件的充电时间预测方法。
