The invention provides an electric vehicle driving range calculation method and system, a storage medium and an electric vehicle. The method comprises the steps that the current environment temperature and the battery pack temperature are collected; judging whether the vehicle starts a battery cell heating function or not; if yes, calculating the first available electricity quantity of the battery pack at the heating cut-off temperature; calculating the first average power consumption of the vehicle within the specified mileage before the current moment; calculating predicted power consumption required by heating according to the current environment temperature, the battery pack temperature and the heating cut-off temperature; calculating the driving range at the current moment according to the first available power consumption, the predicted power consumption and the first average power consumption; if not, calculating a second available electricity quantity of the battery pack at the battery pack temperature; calculating a second average power consumption of the vehicle within a specified mileage before the current moment; and calculating the driving range at the current moment according to the second available power consumption and the second average power consumption. The problem that the driving range of an existing vehicle drastically jumps when the battery cell heating function is started is solved.
本发明提供一种电动汽车续驶里程计算方法、系统、存储介质及电动汽车,所述方法包括:采集当前环境温度及电池包温度;判断车辆是否开启电芯加热功能;若是,则计算电池包在加热截止温度时的第一可用电量;计算当前时刻前指定里程数内车辆的第一平均耗电量;根据当前环境温度、电池包温度及加热截止温度计算出加热所需的预计耗电量;根据第一可用电量、预计耗电量及第一平均耗电量计算出当前时刻的续驶里程;若否,则计算电池包在电池包温度下的第二可用电量;计算当前时刻前指定里程数内车辆的第二平均耗电量;根据第二可用电量及第二平均耗电量计算出当前时刻的续驶里程。本发明解决了现有车辆在开启电芯加热功能时续驶里程大幅跳变的问题。
