[0002] With the increasing popularity of electric vehicles, the performance and lifespan of power batteries have become key factors affecting user experience. Low-temperature environments have a particularly significant impact on battery performance, leading to decreased battery capacity, reduced regenerative braking power, lower charge / discharge efficiency, and even safety hazards. Therefore, developing efficient low-temperature battery thermal management and control strategies is crucial.

[0003] Traditional battery thermal management control strategies typically employ a single heating power and temperature threshold, with heating activation conditions preset based on vehicle charge or temperature. This lacks consideration of different users' driving habits and fails to match personalized heating strategies, resulting in energy waste and significant differences in driving range between different users using the same vehicle or between different users using the same vehicle in low-temperature environments. Summary of the Invention

[0016] The driving style corresponding to each route type is determined based on the range of pedal opening and accelerator pedal activation frequency under the corresponding route type.

[0017] Preferably, the step of matching the target route type of the vehicle's current driving route from historical user profile data includes:

[0018] Determine whether the vehicle's current route is a historical route that the driver has already traveled;

[0019] If the vehicle's current route is a historical route that the driver has already traveled, then the target route type to which the vehicle's current route belongs is matched based on the historical frequency of the vehicle's current route.

[0020] If the vehicle's current route does not belong to the driver's historical routes, the preset route type will be used as the target route type for the vehicle's current route.

[0021] Preferably, if the vehicle's current route does not belong to a historical route already traveled by the driver, the step of matching the corresponding driving style and speed range based on the target route type includes:

[0022] The preset driving style and preset speed range are defined as the driving style and speed range corresponding to the target route type.

[0025] Based on the predetermined correspondence table of driver's driving style, driving speed range, target heating power and target recovery power of the battery under different route types, the driver's driving style and driving speed range under the current driving route are determined, and the target heating power and target recovery power of the battery are determined.

[0026] Preferably, the method further includes:

[0036] The beneficial effects of this invention are as follows:

[0037] By comprehensively considering the driver's driving habits, driving conditions, and the real-time status of the battery, a personalized battery heating strategy has been optimized. Specifically, the target heating power of the battery is dynamically adjusted based on the driver's driving style (smooth, skillful, aggressive) and driving speed range (low, medium, high). This personalized heating strategy effectively addresses the battery thermal management needs under different driving scenarios, ensuring that the battery is always within its optimal operating temperature range. For example, for drivers with an aggressive driving style and high-speed driving, the target heating power is increased to meet their needs for frequent acceleration and high power recovery; while for drivers with a smooth driving style and low-speed driving, the target heating power is reduced to avoid unnecessary energy waste. In addition, by monitoring the remaining battery charge and temperature in real time, the solution can further fine-tune the heating power to ensure battery safety and performance. This personalized heating strategy based on driving habits not only improves battery life and vehicle energy efficiency but also enhances the comfort and adaptability of the driving experience, providing an innovative solution for intelligent thermal management of electric vehicles.

[0040] The method of the present invention will be further described below with reference to the embodiments and accompanying drawings. This embodiment is implemented based on the technical solution of the present invention, and provides detailed implementation methods and specific operating procedures. However, the scope of protection of the present invention is not limited to the following embodiments.

[0041] Reference Figure 1 This application provides a battery thermal management control method, including:

[0042] S101, Based on user profile data and the vehicle's current driving route, identify the driver's driving style and speed range on the current driving route; the user profile data is generated based on the driver's historical driving data;

[0043] S102, determine the target heating power and target recovery power of the battery based on the driver's driving style and speed range under the current driving route;

[0044] S103, based on the battery's real-time remaining charge and real-time temperature, obtains the battery's current maximum recovery power;

[0045] S104, when the current maximum recovery power of the battery is lower than the target recovery power, the battery is heated with the target heating power until the current maximum recovery power of the battery is equal to or exceeds the target recovery power.

[0046] User profile data refers to a comprehensive description generated by collecting and analyzing drivers' historical driving behavior data, including information such as driver identity, route type, driving style, driving speed range, and target heating power and target recovery power of the battery determined based on the driver's driving style and speed range under different route types.

[0047] The driver's identity can be confirmed through methods such as vehicle key, mobile phone connection, or biometrics. After identifying the driver, user profile data is obtained by analyzing the driver's historical driving behavior data. Historical driving behavior data includes: vehicle route, speed, accelerator pedal opening, and frequency of accelerator pedal use.

[0048] When analyzing data to create user profiles, the process includes classifying routes by type, identifying driving styles, and identifying speed ranges.

[0049] Route type classification refers to classifying routes into fixed routes (high-frequency driving), low-frequency routes (low-frequency driving), and regular routes (other routes) based on the driver's historical driving data.

[0050] Fixed routes refer to specific routes that a driver frequently travels over a period of time (such as a month or longer); these routes are usually the driver's daily commute, frequently visited locations (such as between home and work), or fixed travel paths. For fixed routes, the driver's driving time is relatively fixed, such as the daily commute route to and from get off work.

[0051] Low-frequency routes refer to routes that drivers occasionally travel. Although not frequently, these routes have a certain degree of repetition; they may be routes that drivers regularly take to visit a certain location (such as weekend trips to the suburbs or regular visits to relatives and friends). For low-frequency routes, the driving time is not fixed, but there is a certain periodicity.

[0052] Regular routes refer to routes that drivers drive occasionally and without a clear pattern; these routes are usually one-off or non-periodic, and may be travel paths decided on the spur of the moment by the driver. For regular routes, there is no clear pattern in the driver's travel time, destination, and route selection.

[0053] In this embodiment of the application, when classifying driving styles, the driving styles are categorized as smooth, skillful, and aggressive based on the accelerator pedal opening degree and the brake pedal opening frequency.

[0054] A smooth driving style refers to a driving approach characterized by gentle operation, minimal changes in acceleration and deceleration, and smooth braking and acceleration. In this style, the accelerator pedal opening varies little, typically fluctuating within a narrow range to avoid sudden acceleration; the brake pedal is used less frequently, with shallower pedal travel each time to avoid abrupt braking. For example, the accelerator pedal opening fluctuates between 0% and 30%, and the number of braking actions per kilometer is less than 5 (0-5 braking actions per kilometer).

[0055] A skilled driving style refers to a driving approach where the driver operates the vehicle with proficiency, making reasonable use of its performance, exhibiting moderate acceleration and deceleration, and smooth braking and acceleration. In this style, the accelerator pedal opening is moderate, adjusted appropriately according to road conditions to avoid frequent sudden acceleration; the brake pedal opening frequency is also moderate, adjusted appropriately according to road conditions to avoid frequent sudden braking. For example, the accelerator pedal opening fluctuates between 30% and 60%, and the number of braking actions per kilometer is between 5 (excluding 5) and 10.

[0056] Aggressive driving style refers to a driving style characterized by intense maneuvering, significant changes in acceleration and deceleration, and frequent rapid acceleration and braking. Under this style, the accelerator pedal is opened more widely, resulting in frequent rapid acceleration and drastic changes in pedal opening; the brake pedal is used more frequently, leading to frequent sudden braking, and the pedal travel is deeper.

[0057] For example, the accelerator pedal opening fluctuates between 60% and 100%, and the number of braking actions exceeds 10 per kilometer.

[0058] For the same route classification, the speed range is determined based on the vehicle's speed across multiple routes within that route type; specifically, it is determined based on the vehicle's average speed across multiple routes. In this embodiment, based on the average speed, it is divided into a low-speed range (V). 低 ), medium speed range (V) 中 ) and high-speed driving range (V 高 Three speed ranges. Low-speed driving range (V) 低 The speed limit range (V-M) typically refers to urban roads, congested sections, or sections with low speed limits, such as an average speed between 0-40 km / h; the medium speed range (V-M) typically refers to urban expressways, national highways, or provincial highways, such as an average speed between 40-80 km / h; and the high speed range (V-High) typically refers to highways or expressways, such as an average speed between 80-120 km / h.

[0059] After completing the above information identification, it is necessary to combine the driver's above driving habit parameters to find the target heating power and target recovery power that best match the driver's different driving styles and different driving speed ranges under different route types.

[0060] Drivers with a smooth driving style typically operate gently, with low acceleration and deceleration, and smooth braking and acceleration. This driving style has a lower energy demand on the battery, so a lower heating power (P_low) can be used to maintain the battery temperature, and the regenerative braking power demand is also low (p_low). Drivers with a skillful driving style operate with expertise, making reasonable use of vehicle performance, with moderate acceleration and deceleration. This driving style has a moderate energy demand on the battery, so a medium heating power (P_medium) and regenerative braking power (p_medium) can be used. Drivers with an aggressive driving style operate more aggressively, with frequent rapid acceleration and braking. This driving style has a higher energy demand on the battery, so a higher heating power (P_high) is needed to maintain the battery temperature, and the regenerative braking power demand is also high (p_high).

[0061] When driving at low speeds, vehicles frequently start and stop, resulting in numerous braking and acceleration actions. Under these conditions, there are more opportunities for battery recovery, but the power demand for recovery is lower because the vehicle speed is low and the braking energy is small. At the same time, less heat is generated by the battery when driving at low speeds, so the heating power demand is also lower.

[0062] When driving at medium speeds, the vehicle's driving conditions are relatively stable, with moderate braking and acceleration. Under these conditions, the battery recovery opportunities and recovery power requirements are moderate, and the heat generated by the battery is also moderate, so the heating power requirement is also moderate.

[0063] When driving at high speeds, the vehicle's operating conditions are relatively stable, with fewer braking and acceleration actions, but a large amount of energy is recovered during each braking action. Under these conditions, the battery's recovery power requirement is high, and at the same time, the battery generates a lot of heat, so the heating power requirement is also high.

[0064] For a combination of smooth driving and low-speed driving, the vehicle's braking and acceleration actions are less frequent, the energy recovery requirements are lower, and the battery heat generation is less, so lower heating and recovery power can be used.

[0065] For a combination of smooth driving and medium-speed driving, the vehicle's driving conditions are relatively stable, the energy recovery demand is moderate, and the battery heat generation is moderate. Therefore, a moderate heating power and recovery power can be used.

[0066] For smooth driving and high-speed driving: In this combination, the vehicle brakes and accelerates less, but recovers more energy with each braking action and generates more heat from the battery. Therefore, higher heating and recovery power can be used.

[0067] For a combination of skilled driving and low-speed driving, the vehicle's braking and acceleration are moderate, the energy recovery requirements are moderate, and the battery heat generation is moderate. Therefore, moderate heating and recovery power can be used.

[0068] For a combination of skilled driving and moderate-speed driving, the vehicle's operating conditions are relatively stable, the energy recovery requirements are moderate, and the battery heat generation is moderate. Therefore, moderate heating and recovery power can be used.

[0069] For a combination of skilled driving and high-speed driving, the vehicle's braking and acceleration actions are moderate, but the energy recovered during each braking is relatively large, and the battery generates a lot of heat. Therefore, a higher heating power and recovery power can be used.

[0070] For a combination of aggressive driving and low-speed driving, the vehicle experiences more braking and acceleration, resulting in moderate energy recovery requirements and moderate battery heat generation. Therefore, moderate heating and recovery power can be used.

[0071] For a combination of aggressive driving and medium-speed driving, the vehicle undergoes more braking and acceleration, resulting in higher energy recovery requirements and greater battery heat generation. Therefore, higher heating and recovery power can be used.

[0072] For a combination of aggressive driving and high-speed driving, the vehicle undergoes more braking and acceleration actions, resulting in a larger amount of energy recovered during each braking action and a greater amount of heat generated in the battery. Therefore, the highest heating and recovery power can be used.

[0073] The final data is shown in Table 1 below:

[0074]

[0075] Table 1

[0076] In actual control, the thermal management control of the battery can be carried out using Table 1 above.

[0077] In conjunction with S101, during actual control, the vehicle's current route can be determined based on the vehicle's navigation route, and matched with historical routes to obtain the corresponding route type. When the vehicle is not using navigation, multiple real-time positioning data can be used to infer which historical route the vehicle's location falls on, and then match the corresponding route type. That is, by determining whether the vehicle's current route belongs to a historical route already traveled by the driver; if so, the target route type is matched based on the historical frequency of the current route.

[0078] Once the route type is identified, the driving style and speed range of the driver under that route type can be directly determined using the data in Table 1 above, thereby obtaining the corresponding target heating power and target recovery power.

[0079] Considering the actual situation, the historical driving routes stored in the user profile data may not necessarily include the current driving route. In this case, the preset route type is directly used as the target route type to which the vehicle's current driving route belongs; and the preset driving style and preset speed range are determined as the driving style and speed range corresponding to the target route type. Taking this situation as an example, which should be the driver's first route, the preset route type is defined as a regular route, the preset driving style as a smooth driving style under a regular route, and the preset speed range as a low-speed driving range.

[0080] Through the above process, the target heating power and target recovery power of the battery can be determined.

[0081] Then, in step S103, the maximum recovery power at different SOC and temperatures is determined based on the battery's characteristic curve (usually provided by the battery manufacturer).

[0082] Specifically, based on the battery's real-time remaining charge and real-time temperature, the battery's maximum recovery power is calculated using the following formula:

[0083] p max =f(SOC,T)

[0084] Where, p max is the maximum recovery power, SOC is the real-time remaining battery capacity, T is the real-time battery temperature, and f is a function determined based on battery characteristics.

[0085] Then, the relative magnitudes of the battery's current maximum regenerative braking power and the target regenerative braking power are compared. When the battery's current maximum regenerative braking power is greater than the target regenerative braking power, it indicates that the battery has sufficient capacity to meet the target regenerative braking power requirement in its current state. This means that the battery can accept charging at the target regenerative braking power without exceeding its safety and performance limits. In this case, there is no need to heat the battery; the vehicle system can recover energy according to the target regenerative braking power to optimize battery efficiency and vehicle energy consumption performance. Simultaneously, this also helps extend battery life, as the battery operates under suitable conditions, avoiding overcharging or overheating that could potentially damage battery health.

[0086] When the battery's current maximum recovery power is lower than the target recovery power, it indicates that the battery cannot meet the target recovery power requirement under its current state. This is because, at low temperatures, the viscosity of the electrolyte inside the battery increases, the ion diffusion rate slows down, leading to increased internal resistance and limited recovery power. In this case, even if the battery has sufficient remaining charge, the low temperature will restrict its recovery capability. Therefore, it is necessary to activate battery heating to adjust the battery temperature to a suitable range.

[0087] In this embodiment, when heating the battery, the battery is heated with a target heating power until the battery's current maximum recovery power is equal to or exceeds the target recovery power.

[0088] The embodiments described above optimize a personalized battery heating strategy by comprehensively considering the driver's driving habits, driving conditions, and the real-time status of the battery. Specifically, the solution dynamically adjusts the target heating power of the battery based on the driver's driving style (smooth, skillful, aggressive) and driving speed range (low, medium, high). This personalized heating strategy effectively addresses the battery thermal management needs under different driving scenarios, ensuring the battery is always within its optimal operating temperature range. For example, for drivers with an aggressive driving style and high-speed driving, the target heating power is increased to meet their needs for frequent acceleration and high power recovery; while for drivers with a smooth driving style and low-speed driving, the target heating power is reduced to avoid unnecessary energy waste. Furthermore, by monitoring the remaining battery charge and temperature in real time, the solution can further fine-tune the heating power to ensure battery safety and performance. This personalized heating strategy based on driving habits not only improves battery life and vehicle energy efficiency but also enhances the comfort and adaptability of the driving experience, providing an innovative solution for intelligent thermal management of electric vehicles.
