The invention discloses a charge remaining time prediction method, a battery control system and a storage medium, and the method comprises the steps: calculating the maximum charge current according to the charge power and the voltage of a battery pack, the charge power being used for indicating the actual maximum charge power when the battery pack of a vehicle is charged; air conditioner load current is determined according to the working condition of the vehicle, and the working condition is used for indicating the starting state of an air conditioner and a heat management system of the vehicle and the starting sequence of the air conditioner and the heat management system when the air conditioner and the heat management system are started; and calculating the remaining charging time according to the maximum charging current and the air conditioner load current. The calculation of the air conditioner load current in the remaining charging time is determined based on the working condition to which the vehicle belongs, and the working condition to which the vehicle belongs considers the starting state and the starting sequence of the air conditioner and the heat management system, so that the air conditioner load current can be predicted more accurately; and thus, the prediction accuracy of the remaining charging time is improved.

    本申请公开了一种充电剩余时间的预测方法、电池控制系统和存储介质,该方法包括:根据充电功率和电池包的电压计算得到最大充电电流,充电功率用于指示在对车辆的电池包进行充电时的实际最大充电功率;根据车辆所属的工况确定空调负载电流,该工况用于指示车辆的空调和热管理系统的开启状态,以及若空调和热管理系统都开启时空调和热管理系统的开启顺序;根据最大充电电流和空调负载电流计算充电剩余时间。本申请在计算充电剩余时间中空调负载电流是基于车辆所属的工况确定的,同时由于车辆所属的工况考虑到了空调和热管理系统的开启状态和开启顺序,因此能够更为准确地预测得到空调负载电流,进而提高了充电剩余时间的预测准确率。
