Abstract

The embodiment of the invention discloses an electric vehicle endurance method and device, an electric vehicle, equipment and a storage medium. The electric vehicle comprises a power battery, the battery capacity of the power battery comprises available electric quantity and protection electric quantity, and the endurance method of the electric vehicle comprises the steps that the available electric quantity of the power battery is obtained; when the available electric quantity is smaller than or equal to the low electric quantity threshold value, protection electric quantity endurance is activated. According to the technical scheme, the available electricity quantity of the power battery is obtained, the size relation between the available electricity quantity and the low-electricity-quantity threshold value is judged, then a low-electricity-quantity activation reminding instruction is triggered, and after an instruction of agreeing to activate the protection electricity quantity is input outside a vehicle user, the vehicle machine generates the low-electricity-quantity activation signal to be used for endurance of the electric vehicle. Therefore, the emergency situation that the electric vehicle breaks down due to exhaustion of the power battery can be effectively handled, the endurance anxiety of a vehicle user is relieved, and potential safety hazards caused to the driving safety of the vehicle user are reduced.

Description

technical field

[0001] Embodiments of the present invention relate to the technical field of battery life of electric vehicles, and in particular, to a method and device for battery life of electric vehicles, an electric vehicle, equipment, and a storage medium. Background technique

[0002] With the popularization of electric vehicles, more and more vehicle users will encounter the situation that the power battery of electric vehicles is exhausted, especially in winter in the north, because the temperature of the external environment is relatively low, the power battery is more likely to be exhausted Condition. On the one hand, the depletion of the power battery will cause the vehicle user to use the car inconveniently and delay the journey. On the other hand, due to the uncertain location of the breakdown, it may cause great safety hazards to the driving safety of the vehicle user.

[0003] Existing electric vehicles lack targeted countermeasures when the power battery is...
