Specifically, as shown in fig. 1, the battery temperature-raising protection system comprises a collection module 1 and a control module 2, wherein the collection module 1 comprises an ambient temperature sensor 11, a battery temperature sensor 12 and a battery voltage sensor 13, when a vehicle is in a low-temperature environment, the ambient temperature is obtained through the ambient temperature sensor 11, the battery temperature is obtained through the battery temperature sensor 12, and the battery voltage is obtained through the battery voltage sensor 13. The control module 2 receives the battery temperature, the battery voltage and the ambient temperature acquired by the acquisition module 1.
It should be noted that, the low temperature environment is understood to mean that the ambient temperature is lower than 0 ℃.
And S2, determining time information that the battery is not heated to enter the freezing temperature and distance information that the vehicle can travel according to the battery temperature, the battery voltage and the ambient temperature.
Specifically, when the battery reaches the freezing temperature, the electrolyte in the battery may be frozen due to the excessively low temperature, and if the high-voltage battery is used in a frozen state, the high-voltage battery may be degraded. The cell freezing temperature may be-30 ℃. The time information that the battery is not heated to the freezing temperature means the time required for the battery to enter the freezing temperature without performing heating treatment on the battery in a low-temperature environment. The vehicle travelable distance information refers to the distance that the remaining electric energy can support the vehicle to travel after the electric energy required by the battery to prevent freezing is subtracted from the electric energy of the battery. The control module 2 determines time information that the battery is not heated to a freezing temperature and distance information that the vehicle can travel based on the battery temperature, the battery voltage, and the ambient temperature.

s11, acquiring the battery temperature, the battery voltage and the ambient temperature.
And S12, determining time information that the battery is not heated to enter the freezing temperature according to the battery temperature and the ambient temperature, and information about electric energy required by the battery to prevent freezing.
Specifically, as shown in fig. 1, the control module 2 includes a vehicle controller 22, and in the actual development process, actual tests are performed on how much the battery is reduced after a long time of the battery in different temperature environments, and a large amount of experimental data form a database, which may be pre-stored in the vehicle controller 22. Illustratively, when the battery temperature is 0 ℃, the ambient temperature is-20 ℃, it takes 1 hour for the battery temperature to decrease from 0 ℃ to-10 ℃. Therefore, when the battery temperature and the ambient temperature are determined, the vehicle controller 22 obtains the time information that the battery is not heated to the freezing temperature by querying the database.
The vehicle controller 22 has a learning function, and can record the historical data of how much electric energy is consumed by the battery when the battery is raised to a certain degree at different ambient temperatures to form a historical database, and the consumption of the battery is about 2.9% of the electric energy when the battery is raised to-20 ℃ at-30 ℃ and the ambient temperature is-20 ℃. Therefore, when the battery temperature and the ambient temperature are determined, the vehicle controller 22 obtains the electric energy information required by the battery to prevent freezing by querying the history database.
And S13, determining the battery power according to the battery voltage.
Specifically, the control module 2 includes a battery management system controller 21, determines that the battery power needs to be known about the capacity and voltage of the battery, and after the battery voltage, the battery temperature and the ambient temperature are obtained, the battery management system controller 21 can calculate the current power of the battery according to the battery voltage, the battery temperature and the ambient temperature, and finally obtain the battery power according to the battery power and the battery voltage.
And S14, determining distance information according to the battery power, the power information required by the battery to prevent freezing and the environment temperature.
Specifically, the walkable distance of the electric vehicle is not only related to the remaining battery power but also related to the ambient temperature, and the walkable distance is longer as the ambient temperature is higher, whereas the walkable distance is shorter as the ambient temperature is lower, so that the control module 2 can determine the distance information according to the battery power, the power information required for preventing the battery from freezing, and the ambient temperature.
And S15, feeding back time information, battery temperature and distance information to the terminal.

Specifically, battery residual electric energy information can be obtained by subtracting the electric energy required by battery freezing prevention from the battery electric energy, and the walkable distance of the electric vehicle can be determined by combining the electric vehicle hundred kilometer energy consumption according to the residual electric energy information and the ambient temperature. Accordingly, the vehicle controller 22 may determine battery remaining power information based on the battery power and the battery freeze prevention required power information, and ultimately determine distance information based on the remaining power information and the ambient temperature.
According to the embodiment of the invention, the battery temperature is predicted and calculated in the future through the whole vehicle controller, the freezing temperature of the battery is calculated as to how long the battery is to enter if the battery is not heated, meanwhile, the electric energy required by the battery for preventing freezing and the electric energy of the battery are calculated through the whole vehicle controller, and the walkable distance of the electric vehicle is calculated after the electric energy required by the battery for preventing freezing is subtracted from the electric energy of the battery. So that a user can make a subsequent travel plan according to the time information that the battery is not heated to enter the freezing temperature and the distance information that the vehicle can travel.

Or, S243, receiving a heating function instruction not started fed back by the terminal, and controlling the air conditioning system to send a heating request according to the heating function instruction not started, so as to control the air conditioning system not to heat the battery.
Specifically, after receiving the feedback time information, the battery temperature and the distance information of the whole vehicle controller 22, the user determines whether to immediately start the battery temperature raising mode, and inputs a first operation instruction through the terminal, where the first operation instruction is a preset mode, and the user may select a corresponding mode according to the own vehicle plan.
Mode one: the battery heating function is immediately turned on.
Mode two: and the heating function of the battery is delayed to be started.
