[0047] The purpose, features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0048] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0049] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0050] The main solution of this application embodiment is: a vehicle driving battery thermal management method, including: obtaining current driving path information, querying a set of path thermal management strategies based on the current driving path information, determining a target path thermal management strategy, and controlling vehicle driving according to the target path thermal management strategy.

[0051] In this embodiment, for ease of description, the following description will focus on identifying the vehicle-mounted computer as the executing entity.

[0052] Current technology in the power battery thermal management strategy generally adopts a static threshold, which means that the current threshold cannot be dynamically adjusted and can only respond passively. Cooling is activated when the battery temperature exceeds a certain value and heating is activated when the battery temperature falls below a certain value, which cannot meet the needs of users under various operating conditions.

[0053] This application provides a solution that uses this method to match and select different route thermal management strategies based on the current driving path, thereby adjusting the thermal management strategy for different road conditions to better suit the road conditions. At the same time, the set of route thermal management strategies is also set based on user habits, making it more user-friendly.

[0054] It should be noted that the executing entity in this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, or mobile phone, or an electronic device or in-vehicle computer capable of performing the above functions. The following description uses an in-vehicle computer as an example to illustrate this embodiment and the subsequent embodiments.

[0055] Based on this, embodiments of this application provide a method for thermal management of a vehicle's driving battery, referring to... Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the vehicle driving battery thermal management method of this application.

[0056] In this embodiment, the vehicle driving battery thermal management method includes steps S10 to S20:

[0057] Step S10: Obtain the current driving route information, and query the route heat management strategy set based on the current driving route information to determine the target route heat management strategy;

[0058] It should be noted that the solution in this embodiment is to first record the user's driving route, match an initial thermal management strategy for each route, optimize the thermal management strategy for each route based on the driving conditions of each route, and then when the user drives again, if it matches the recorded and stored route, the thermal management strategy for that route is directly adopted and optimized; if it does not match, a new route is created, the corresponding thermal management strategy is stored, and optimization is performed again, and so on, until all of the user's driving routes are covered.

[0059] It should be understood that, firstly, the current driving route information is obtained, including the current vehicle location and the final navigation destination. Then, the corresponding heat management strategy for the same or approximately the same route found in the set of route heat management strategies is used as the target route heat management strategy.

[0060] In one feasible implementation, before invoking the set of path thermal management strategies, it is necessary to pre-store thermal management strategies for different paths. Before step S10, the method further includes: acquiring historical vehicle driving data; determining battery temperature data and vehicle driving path data based on the historical vehicle driving data; establishing multiple path thermal management strategies based on the battery temperature data and vehicle driving path data; and establishing a set of path thermal management strategies based on the path thermal management strategies.

[0061] It should be noted that the starting latitude and longitude coordinates Star01(x,y) and ending latitude and longitude coordinates End01(x,y) of each user's single driving trip are obtained from the vehicle's historical driving data, and stored as a path A(0,1)...A(m,n) (where m represents the same starting point and n represents the same ending point). Each path corresponds to a thermal management strategy, that is, multiple path thermal management strategies are obtained, and then the path thermal management strategy set is obtained by summarizing them.

[0062] It should be understood that if the distance between the starting point and the destination of the user's vehicle driving next time does not exceed 1 kilometer, the heat management strategy of the previous path will still be used. Otherwise, a new path A(m,n) should be set up to store the new heat management strategy. If the distance between the starting point and the previous starting point does not exceed 1 kilometer, then m is the same; otherwise, it is taken in order. If the distance between the destination and the previous destination does not exceed 1 kilometer, then n is the same; otherwise, it is taken in order.

[0063] In the specific implementation, each path A(0,1)...A(m,n) is obtained, and the corresponding thermal management strategy is: cooling is turned on when the battery maximum temperature Tmax≥35℃, and cooling is turned off when Tmax≤33℃ (taking cooling as a simple example, other thermal management strategies are similar in logic). Each path is initially set with the above thermal management strategy, and the battery temperature T0 at the beginning of each path, the ambient temperature Te, the temperature at the end of the path T1, and the highest temperature Tmax1 during the journey are obtained.

[0064] Step S20: Control the vehicle's movement according to the target path thermal management strategy.

[0065] It should be noted that in order to accurately control vehicle movement, the temperature at which thermal management is turned on and off needs to be determined based on the target path thermal management side path, thereby ensuring the health of the battery pack.

[0066] In one feasible implementation, in order to accurately control the vehicle, step S20 includes: determining a cooling control temperature and a heating control temperature according to the target path thermal management strategy; and controlling battery cooling and heating during vehicle operation according to the cooling control temperature and the heating control temperature.

[0067] It should be understood that, firstly, the cooling control temperature and heating control temperature are determined according to the target path thermal management strategy. That is, the entry and exit temperatures for cooling the battery pack, and the entry and exit temperatures for heating the battery pack. This ensures normal operation while minimizing battery pack safety and energy consumption.

[0068] In one feasible implementation, in order to optimize the thermal management strategy after each trip, after step S20, the method further includes: recording the battery temperature information and ambient temperature information of this trip; determining the starting battery temperature, the ending battery temperature, and the highest temperature along the way based on the battery temperature information; optimizing the target path thermal management strategy based on the starting battery temperature, the ending battery temperature, the highest temperature along the way, and the ambient temperature information; and updating the path thermal management strategy set based on the optimized target path thermal management strategy.

[0069] It should be noted that the thermal management strategy optimization logic is as follows: if Tmax1 ≤ 45℃ during each route, the battery thermal management strategy should be optimized to bring Tmax1 closer to 45℃ (this threshold is the highest continuous operating temperature of the battery cell that does not affect battery life, obtained by the battery manufacturer through experimental testing, and varies for different cells), thereby maximizing the saving of battery thermal management energy consumption. Then, based on this threshold, along with parameters such as the starting battery temperature, ending battery temperature, and highest temperature along the route, and combined with the start and stop temperatures of thermal management during the specific driving process, an analysis is conducted to determine whether to modify the thermal management parameters of the target route's thermal management strategy.

[0070] In one feasible implementation, to accurately determine how to optimize the thermal management strategy, the step of optimizing the target path thermal management strategy based on the starting battery temperature, the ending battery temperature, the highest temperature along the way, and the ambient temperature information includes: obtaining ambient temperature influence parameters and thermal management activation temperature information; determining an updated thermal management activation temperature and an updated thermal management deactivation temperature based on the starting battery temperature, the ending battery temperature, the highest temperature along the way, the ambient temperature, the ambient temperature influence parameters, and the thermal management activation temperature information; and optimizing the target path thermal management strategy based on the updated thermal management activation temperature and the updated thermal management deactivation temperature.

[0071] It should be understood that the optimized thermal management cooling activation threshold for this driving scenario is Tmax ≥ T_activation + (45℃ - Tmax1) - (T01 - T0) + (a0 + b0Te). Here, 45℃ is the highest continuous operating temperature of the battery cell that does not affect battery life, obtained by the battery manufacturer through experimental testing, and varies for different cells. T0 is the initial driving temperature stored under the corresponding driving path, T01 is the initial battery temperature under the corresponding driving path, Tmax1 is the highest temperature stored during the driving process under the corresponding driving path, T_activation is the thermal management activation temperature stored under the corresponding driving path, and (a0 + b0Te) is the influence of ambient temperature on thermal management cooling activation. Cooling exit temperature = activation temperature - 2℃ (hysteresis interval); after multiple training sessions on the same path, the thermal management strategy for this path is summarized as T_activation = a + bX + cY, where X is the initial battery temperature and Y is the ambient temperature.

[0072] This embodiment provides a method for vehicle battery thermal management. It acquires current driving route information, queries a set of route thermal management strategies based on this information, and determines a target route thermal management strategy. The vehicle's movement is then controlled according to the target route thermal management strategy. This approach achieves the matching and selection of thermal management strategies corresponding to different routes based on the current driving route. This allows for adjustments to the thermal management strategy for different road conditions, making it more adaptable to road conditions. Furthermore, the set of route thermal management strategies is also set based on user habits, further enhancing user experience.

[0073] Based on the first embodiment of this application, in the second embodiment of this application, the content that is the same as or similar to that in Embodiment 1 above can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 2 Step S10 includes steps S101 to S102:

[0074] Step S101: Obtain the current driving route information, and determine the current starting point information and current ending point information based on the current driving route information;

[0075] It should be noted that the current driving route information is obtained first, including but not limited to the starting point and destination, as well as the route already traveled and the current road.

[0076] Step S102: Query the set of path heat management strategies based on the current starting point information and the current ending point information to obtain multiple alternative path heat management strategies;

[0077] It should be understood that after determining the current starting point information and the current key information, a query is performed in the set of path heat management strategies to identify multiple alternative path heat management strategies for selection.

[0078] In practice, when the vehicle starts, it is positioned as Star(a,b). It automatically searches for paths that differ from the latitude and longitude (a,b) by 1 kilometer. If no such path is found, a new path is created and matched with the initial thermal management strategy. If n paths are found that differ from the longitude of Star(a,b) by 1 kilometer, then there are n alternative thermal management strategies.

[0079] Step S103: Determine the target path thermal management strategy from the candidate path thermal management strategies.

[0080] It should be noted that in order to determine the target path thermal management strategy, it is necessary to judge the path similarity and select the thermal management strategy corresponding to the path with the highest similarity from the candidate path thermal management strategies as the target path thermal management strategy.

[0081] In a feasible implementation, in order to accurately select a target path heat management strategy, step S103 includes: determining a driving route based on the current driving route information; calculating the similarity between the driving route and the candidate paths corresponding to each candidate path heat management strategy; selecting a target path from each candidate path based on the similarity, and using the candidate path heat management strategy corresponding to the target path as the target path heat management strategy.

[0082] It should be understood that if n paths are found that differ from Star(a,b) by 1 kilometer in longitude, driving begins, and the drive(x,y) coordinates are updated in real time. The vehicle's trajectory is compared with the trajectories of the n paths that share the same starting point (i.e., the current driving trajectory of the starting point (a,b) and drive(x,y) is compared with the trajectory from the starting point to drive(x,y) of the n paths that share the same starting point; a trajectory deviation ≤100m is considered similar). If the similarity is ≥90% (calibrated), the current path is considered the same as a path with ≥90% similarity (meaning the user is driving towards their usual destination, such as a fixed location for commuting in the morning or evening). Otherwise, a new path is created... If multiple stored paths have a similarity higher than 90% with the current path, the path whose thermal management is activated first is selected to cover all possible path scenarios. As the user continues driving, when a path is finally locked, the thermal management cooling strategy for that path is switched.

[0083] This embodiment obtains the current driving route information and determines the current starting point and current destination information based on it. It then queries a set of route thermal management strategies based on the current starting point and current destination information to obtain multiple candidate route thermal management strategies. Finally, it determines the target route thermal management strategy from these candidate strategies. In this way, it selects the most appropriate thermal management strategy corresponding to the driving conditions and road conditions as the thermal management strategy for this trip, improving the suitability of the thermal management strategy for road conditions.

[0084] It should be noted that the above examples are only for understanding this application and do not constitute a limitation on the vehicle driving battery thermal management method of this application. Any simple modifications based on this technical concept are within the protection scope of this application.

[0085] This application also provides a vehicle battery thermal management device; please refer to... Figure 3 The vehicle battery thermal management device includes:

In this way, it achieves matching and selection of thermal management strategies corresponding to different routes based on the current driving route, thereby allowing for adjustments to the thermal management strategy for different road conditions, making it more suitable for road conditions. Furthermore, the set of route thermal management strategies is also summarized and set according to user habits, making it even more user-friendly.
