The invention relates to the technical field of electric vehicles, and provides a battery endurance mileage display method and device and an electric vehicle. The method comprises the steps that when a battery limit endurance mode of a vehicle is started, the real remaining electric quantity of a battery pack and the corresponding hidden endurance mileage are calculated when the vehicle meter display SOC is 0%, and part of the hidden endurance mileage is superposed to the current vehicle meter display endurance mileage to obtain a new meter display endurance mileage; the new meter display endurance mileage and the vehicle meter display SOC are matched and bound, and when the meter display endurance mileage of the vehicle is zero, the vehicle meter display SOC is 0%; and displaying the new meter display endurance mileage, and updating the vehicle meter display SOC based on the new meter display endurance mileage. According to the method, the partial endurance mileage in the hidden endurance when the vehicle still can run after the vehicle meter display SOC is 0% is displayed to the user, it is guaranteed that the battery pack still has the remaining electric quantity when the meter display SOC is 0, the driving confidence of the battery pack to the user is not damaged, and the mileage anxiety psychology of the user is reduced.

    本申请涉及电动汽车技术领域,提供了一种电池续航里程显示方法、装置和电动汽车。该方法包括:当车辆开启电池极限续航模式时,计算车辆表显SOC在0%时电池包的真实剩余电量及其对应的隐藏续航里程,并将部分该隐藏续航里程叠加至当前车辆表显续航里程中,得到新的表显续航里程;对新的表显续航里程与车辆表显SOC进行匹配绑定,使车辆的表显续航里程为零时,车辆表显SOC为0%;显示新的表显续航里程,并基于该新的表显续航里程更新车辆表显SOC。本申请将车辆表显SOC为0%后车辆依旧能够行驶的隐藏续航中的部分续航里程显示给用户,既保证在仪表显示SOC为0时电池包仍有剩余电量,也不损伤电池包给与用户驾驶信心,减少了用户的里程焦虑心理。
