The invention relates to the technical field of electric vehicles, in particular to a method, device and system for determining the endurance mileage, an electric vehicle and a storage medium, firstly, the current driving energy consumption and mileage of the electric vehicle are obtained, and the real-time average energy consumption is determined according to the current driving energy consumption and mileage; then, a historical driving sequence of the electric vehicle is obtained, an effective driving sequence is determined according to the historical driving sequence, the historical driving sequence comprises historical driving information arranged according to the time sequence, and each piece of historical driving information corresponds to mileage and energy consumption; and determining historical average energy consumption according to the effective driving sequence. And finally, determining the endurance mileage according to the historical average energy consumption, the real-time average energy consumption and the available residual energy. The effective driving sequence is determined to be updated along with continuous accumulation of the historical driving sequence, so that the historical average energy consumption can reflect the average energy consumption performance of the electric vehicle in the recent period, and the estimation precision of the endurance mileage can be improved.
本申请涉及电动汽车技术领域,具体涉及一种确定续航里程的方法、装置、系统、电动汽车和存储介质,首先,获取电动汽车的当前行驶的能耗和里程,并根据当前行驶的能耗和里程,确定实时平均能耗。然后,获取电动汽车的历史行驶序列,并根据历史行驶序列,确定有效行驶序列,其中,历史行驶序列包括按时间顺序排列的历史行驶信息,各历史行驶信息对应有里程和能耗。根据有效行驶序列,确定历史平均能耗。最后,根据历史平均能耗、实时平均能耗和可用剩余能量,确定续航里程。有效行驶序列是随着历史行驶序列的不断累积而确定更新的,使得历史平均能耗能够反映近期电动汽车的平均能耗表现,从而,能够提高续航里程的估算精度。
