The invention provides a charging method and system based on power battery charging urgency degree quantification. The method comprises the following steps: determining a travel urgency degree; real-time state data in the charging process of the power battery is collected, the battery core temperature is solved according to a battery model, and the upper limit of the battery core temperature can change along with the change of the travel urgency degree, namely, the upper limit of the battery core temperature can correspondingly rise when the travel urgency degree is improved; establishing and training a battery rapid charging model considering the user travel urgency degree; according to the battery rapid charging model considering the user travel urgency degree, the optimal charging current of the battery at the current moment is solved according to the travel urgency degree and the collected real-time state data and core temperature data in the battery charging process, and the power battery is charged according to the optimal charging current.

    本发明提出了一种基于动力电池充电紧迫程度量化的充电方法及系统,包括:确定出行紧迫程度;采集动力电池充电过程中实时状态数据,并根据电池模型求解电池核心温度,所述电池核心温度上限会随着出行紧迫程度的变化而发生改变,即出行紧迫程度提高,电池核心温度上限也会相应上升;建立并训练计及用户出行紧迫度的电池快速充电模型;所述计及用户出行紧迫度的电池快速充电模型根据出行紧迫度和采集的电池充电过程中实时状态数据以及核心温度据,求解当前时刻电池的最优充电电流,动力电池根据该最优充电电流进行充电。
