[0023] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0025] After being parked for a long time in a cold environment, the temperature of the power battery or low-voltage battery on the car will approach the ambient temperature. However, the battery is usually not allowed to discharge at -30℃ or below because the temperature is too low. This may cause the user to be unable to start the vehicle when using it again, and can only use an external power supply to assist in starting, or wait for the battery to slowly heat up, thus disrupting the user's normal life rhythm and affecting the user's car experience.

[0026] In order to solve the problems of the prior art, the embodiments of the present application provide a method, device and related equipment for preheating a car battery. The method for preheating a car battery provided by the embodiments of the present application is first introduced below.

[0027] Figure 1 FIG. 1 is a flow chart of a method for preheating a vehicle battery provided by an embodiment of the present application. Figure 1 As shown, a method for preheating a car battery may include the following steps S101 to S104.

[0028] S101, when the vehicle is in a parked state, obtaining an initial temperature of the vehicle battery, an ambient temperature, and a parking time of the vehicle;

[0029] S102, in a preset corresponding relationship, determining the parking duration corresponding to the ambient temperature, the initial temperature and the preset first temperature threshold as the pre-power-off duration of the vehicle battery, wherein the corresponding relationship is used to indicate the corresponding relationship between each battery temperature and each parking duration under different ambient temperature ranges and different initial temperatures of the vehicle battery;

[0030] S103, calculating the parking time and the pre-power-off duration to determine the preheating time of the vehicle battery;

[0031] S104: heating the vehicle battery during preheating.

[0032] The car battery preheating method of the embodiment of the present application can obtain the initial temperature of the car battery, the ambient temperature and the parking time of the car when the car is in the parking state; in the preset corresponding relationship, the parking time corresponding to the ambient temperature, the initial temperature and the preset first temperature threshold is determined as the pre-power-off time of the car battery, and the corresponding relationship is used to indicate the relationship between each battery temperature and each parking time under different ambient temperature ranges and different initial temperatures of the car battery; the parking time and the pre-power-off time are calculated to determine the preheating time of the car battery; and the car battery is heated at the preheating time. In this way, the embodiment of the present application can predict the pre-power-off time of the car battery in a low temperature environment according to the initial temperature and ambient temperature of the car battery and the preset corresponding relationship, and then determine the preheating time of the car battery in combination with the parking time of the car, and heat the car battery at the preheating time, so that the car battery will not be unable to discharge due to too low temperature, and will not interfere with the normal use of the user, thereby improving the user's car experience.

[0033] The above-mentioned automobile battery preheating method is mainly applied to vehicle terminals. The present application is not limited thereto, and can also be a terminal device with data processing capabilities such as a vehicle central control system or a cloud server.

[0034] The specific implementation methods of the above steps are introduced below.

[0035] In S101, the above-mentioned automobile may be an automobile including a power battery or a low-voltage battery. For example, it may be a pure electric new energy automobile, or a traditional internal combustion engine vehicle equipped with a low-voltage battery.

[0036] The above-mentioned car battery can be a power battery or a low-voltage battery. Among them, the power battery can be a lithium-ion battery, which can be composed of a battery cell and a protection circuit board. A low-voltage battery refers to a rechargeable battery with a lower rated voltage. Generally speaking, the voltage range of a low-voltage battery is usually between 3V and 12V. Low-voltage batteries are widely used in various electronic devices and systems, such as automotive auxiliary systems, home emergency power supplies, electronic toys, handheld appliances, etc. They usually use chemical reactions to store and release electrical energy, and can be charged by an external power source.

[0037] The above-mentioned parking state specifically refers to a state in which the car is parked and powered off.

[0038] The initial temperature of the automobile battery may be the initial temperature of the automobile battery when the automobile is in a parked state.

[0039] The above-mentioned ambient temperature may be the ambient temperature of the vehicle when the vehicle is in a parked state, but is not limited thereto. The ambient temperature may also include the temperature in a future period as predicted by the weather forecast.

[0040] In S102, the above correspondence can be used to indicate the correspondence between each battery temperature and each parking time under different ambient temperature ranges and different initial temperatures of the vehicle battery. The battery temperature is the real-time temperature of the vehicle battery.

[0041] The above-mentioned first temperature threshold can be the lowest temperature at which the car battery can meet the user's minimum car usage needs. For example, the car battery of a hybrid vehicle can still meet the engine's starting power at -35°C, and the vehicle can then be driven by fuel without the need for the car battery to be discharged for a long time; while the car battery of a pure electric vehicle must be above -30°C to be continuously discharged.

[0042] In the above-mentioned preset corresponding relationship, the parking time corresponding to the ambient temperature, the initial temperature and the preset first temperature threshold is determined as the pre-power-off time of the vehicle battery. For example, in the preset multiple corresponding sub-relationships, the corresponding sub-relationship corresponding to the ambient temperature and the initial temperature is determined as the target corresponding sub-relationship; in the target sub-corresponding relationship, the parking time corresponding to the preset first temperature threshold is determined as the pre-power-off time of the vehicle battery. Alternatively, in the preset corresponding relationship, the initial temperature, the ambient temperature and the temperature of the future time period in the weather forecast are used to determine the battery temperature corresponding to each unit parking time (for example, 1 hour) of the vehicle battery one by one, and the parking time when the battery temperature is less than or equal to the first temperature threshold is determined as the pre-power-off time of the vehicle battery.

[0043] In some embodiments, the above correspondence relationship may include multiple corresponding sub-relationships, and different corresponding sub-relationships correspond to different ambient temperature ranges and different initial temperatures of the vehicle battery;

[0044] The above S102 may specifically include:

[0045] Among the preset multiple corresponding sub-relations, determining the corresponding sub-relations corresponding to both the ambient temperature and the initial temperature as the target corresponding sub-relations;

[0046] In the target sub-correspondence, the parking time corresponding to the preset first temperature threshold is determined as the pre-power-off time of the vehicle battery.

[0047] The above-mentioned corresponding sub-relationships can be used to indicate the corresponding relationship between each battery temperature and each parking time in each ambient temperature range and each initial temperature.

[0048] In this embodiment, by directly determining the corresponding sub-relationship corresponding to both the ambient temperature and the initial temperature as the target corresponding sub-relationship in the preset multiple corresponding sub-relationships, and in the target sub-corresponding relationship, the parking time corresponding to the preset first temperature threshold is quickly determined as the pre-power-off time of the vehicle battery, thereby improving data processing efficiency.

[0049] As an implementation of the present application, in order to accurately determine the pre-power-off duration of the vehicle battery, before the above S102, the following steps may also be included:

[0050] Acquire historical data of multiple vehicle batteries, the historical data including historical ambient temperature of the vehicle batteries, historical first temperature of the vehicle batteries at the beginning of vehicle parking, and historical second temperature of the vehicle batteries at various parking durations;

[0051] Establish multiple corresponding sub-relationships by associating multiple historical data according to different preset ambient temperature ranges, different initial temperatures, different parking durations, and different battery temperatures;

[0052] A corresponding relationship is generated according to a plurality of corresponding sub-relationships.

[0053] The above historical data may include the historical ambient temperature of the vehicle battery, the historical first temperature of the vehicle battery at the beginning of the vehicle parking, and the historical second temperature of the vehicle battery at various parking durations. The historical first temperature is the historical battery temperature of the vehicle battery at the beginning of the vehicle parking at the historical ambient temperature, and the historical second temperature is the historical battery temperature of the vehicle battery at different parking durations at the historical ambient temperature.

[0054] In this embodiment, through the historical data of multiple car batteries, multiple corresponding sub-relationships are established according to the association between different preset ambient temperature ranges, different initial temperatures, different parking times and different battery temperatures, and an accurate corresponding relationship can be obtained, thereby accurately determining the pre-power-off time of the car battery.

[0055] In S103, the preheating time of the vehicle battery is a time associated with the parking time and the pre-power-off duration.

[0056] In some embodiments, the above S103 may specifically include:

[0057] Add the parking time and the expected power-off duration to obtain the expected power-off time of the car battery;

[0058] The preheating time of the vehicle battery is obtained by subtracting the pre-power-off time from the preset time, and the preset time is less than the pre-power-off time.

[0059] The above-mentioned pre-power-off time means the time when the car battery cannot meet the user's minimum car use demand after the pre-power-off time since the car was parked.

[0060] The above-mentioned preheating time is obtained by subtracting the pre-power-off time from the preset duration, which means that the vehicle battery needs to be heated before the pre-power-off time.

[0061] The above-mentioned preset duration, illustratively, may be 30 minutes, but is not limited thereto in the present embodiment and may also be other values, which are not specifically limited here.

[0062] In this embodiment, the parking time is added to the pre-power-off time to obtain the pre-power-off time of the car battery, and the pre-power-off time is subtracted from the preset time to accurately determine the preheating time of the car battery, so as to heat the car battery at the preheating time and ensure the user's normal car use needs.

[0063] As another implementation of the present application, in order to prevent the vehicle from being unusable due to the low temperature of the vehicle battery, after the pre-power-off time is subtracted from the preset time length to obtain the preheating time of the vehicle battery, the following may also be included:

[0064] A reminder message is sent to the user of the car at the preheating time, and the reminder message is used to remind the user to perform thermal insulation treatment on the car battery.

[0065] The above-mentioned insulation treatment, illustratively, can be to move the vehicle to a place with higher temperature, such as a basement; or, to park the vehicle near the charging facility, connect the charging gun, and turn on the battery insulation function, that is, use the power of the charging pile to keep the car battery warm to prevent the car battery temperature from being too low; or to prepare the charging harness, when the car is needed after 8 hours, if the car battery temperature is still too low, plug in the gun for charging and heat the car battery.

[0066] In this embodiment, a reminder message is sent to the user of the car in time at the preheating time, and the reminder message is used to prompt the user to perform heat preservation treatment on the car battery, so as to avoid the car battery temperature being too low and causing the vehicle to be unusable.

[0067] In S104, the vehicle battery is heated. Exemplarily, this can be achieved by a heating sheet attached to the surface of the vehicle battery or by a heat carrier in a liquid cooling plate. In the present application, the heating method is not limited thereto and other heating methods may also be used, which are not specifically limited here.

[0068] In some embodiments, the above S104 may specifically include:

[0069] determining a target temperature associated with a first temperature threshold, the target temperature being greater than the first temperature threshold;

[0070] The vehicle battery is heated to the target temperature during the preheating period.

[0071] Since the greater the difference between the battery temperature and the ambient temperature, the faster the heat dissipation rate, the target temperature does not need to be too far from the first temperature threshold to reduce energy consumption and slow down the heat loss of the vehicle battery. The above target temperature can be, for example, a temperature 10°C higher than the first temperature threshold. In this embodiment, the target temperature is not limited to this, but can also be other values, which are not specifically limited here.

[0072] In this embodiment, by determining the target temperature associated with the first temperature threshold, the vehicle battery is heated to the target temperature during preheating, thereby reducing energy consumption and slowing down heat loss from the vehicle battery while ensuring that the vehicle battery can meet the user's minimum vehicle usage needs.

[0073] As another implementation of the present application, in order to avoid the situation where the vehicle battery temperature is too low during preheating and the vehicle cannot be used, the above method may further include:

[0074] According to the preset time period, the battery temperature of the vehicle battery is obtained regularly;

[0075] When the battery temperature is less than or equal to a preset second temperature threshold, the vehicle battery is heated, the second temperature threshold is associated with the first temperature threshold, and the second temperature threshold is greater than the first temperature threshold.

[0076] The above-mentioned preset time period may be, for example, 1 hour.

[0077] Compared with obtaining the battery temperature of the vehicle battery in real time, the above-mentioned regular acquisition of the battery temperature of the vehicle battery can save more energy of the vehicle battery.

[0078] The above-mentioned second temperature threshold is associated with the first temperature threshold, and the second temperature threshold is greater than the first temperature threshold. Exemplarily, the second temperature threshold is 2°C higher than the first temperature threshold. In this embodiment, the second temperature threshold is not limited to this, but can also be other values, which are not specifically limited here.

[0079] In this embodiment, the battery temperature of the vehicle battery is obtained at a preset time period, and the vehicle battery is heated when the battery temperature is less than or equal to a preset second temperature threshold, so as to avoid the situation where the battery temperature of the vehicle battery is too low during the preheating time and the vehicle cannot be used, thereby ensuring that the user can use the vehicle normally.

[0080] In order to facilitate the understanding of the automobile battery preheating method in the embodiment of the present application, the application process of the automobile battery preheating method is described here, as follows:

[0081] The present application embodiment provides a method for preheating a car battery, and the specific steps are as follows:

[0082] 1. Through testing or simulation, the lowest temperature (equivalent to the first temperature threshold) at which the car battery can meet the user's minimum car use needs is obtained, which is recorded as Tmin. For example, the car battery of a hybrid vehicle can still meet the engine starting power at -35°C, and the vehicle can then be driven by fuel without the need for the car battery to discharge for a long time; the car battery of a pure electric vehicle must be above -30°C to discharge continuously.

[0083] 2. According to user big data, count the parking time, initial parking temperature, and ambient temperature of the vehicle, and select parameter values ​​with a higher probability of occurrence. For example, excluding short parking, the parking time is mostly 1h, 2h, 3h, 8h, 10h, 12h, etc.

[0084] 3. By testing or establishing a simulation model, the relationship between the real-time battery temperature (i.e., the above-mentioned battery temperature) and the parking time under different ambient temperatures and different initial temperatures in Article 2 is obtained. The form can be as shown in Table 1 below, or it can be a function, such as the real-time battery temperature = f (ambient temperature, battery initial temperature, parking time), and then this relationship is written into the vehicle-side or cloud controller.

[0085] Table 1:

[0086]

[0087] 4. When the user parks the car and powers off the power, the battery temperature corresponding to different parking times is predicted based on the current battery temperature, the current ambient temperature collected by the vehicle, and the content in Article 3. For example, it is expected that the battery temperature will be lower than Tmin after 8 hours.

[0088] 5. In order not to affect the user's normal use of the vehicle, it is necessary to send a message to the user via SMS, APP or manual method before the predicted battery temperature is lower than Tmin (i.e. the above-mentioned preheating time) to remind the other party to take preventive measures, including:

[0089] (1) It is recommended to move the vehicle to a place with higher temperature, such as a basement.

[0090] (2) It is recommended to park the vehicle near a charging facility, connect the charging gun, and turn on the battery insulation function, that is, use the power of the charging pile to keep the battery warm to prevent the battery temperature from being too low; or prepare the charging harness. When the vehicle is needed after 8 hours, if the battery temperature is too low, plug in the gun to charge and heat the battery.

[0091] (3) Before predicting that the battery temperature is lower than Tmin, the battery temperature is actively heated to a safe range above Tmin through a heating device. The heating process can be achieved through a heating sheet attached to the surface of the battery or through a heat carrier in a liquid cooling plate. The battery temperature does not need to be too high at the end of heating. For example, it can be heated only to Tmin+10°C (equivalent to the above target temperature) to reduce energy consumption and slow down the heat loss of the battery - the greater the difference between the battery temperature and the ambient temperature, the faster the heat dissipation rate.

[0092] In order to avoid inaccurate predictions leading to low battery and inability to use the vehicle normally, the user can also be asked to authorize the vehicle-side signal collector and controller to be woken up regularly. When the battery temperature is found to be too low (for example, Tmin+2°C, equivalent to the second temperature threshold mentioned above), a certain amount of electricity is consumed and the battery temperature is raised to a safe range above Tmin through a heating device.

[0093] Based on the vehicle battery preheating method provided in the above embodiment, the present application also provides a specific implementation of a vehicle battery preheating device. Please refer to the following embodiment.
