[0031] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0032] The following description, with reference to the accompanying drawings, outlines an embodiment of the present invention, including a battery temperature pre-regulation method, a controller, a computer-readable storage medium, a battery temperature pre-regulation device, and a vehicle.

[0033] Figure 1 This is a flowchart of a battery temperature pre-conditioning method according to an embodiment of the present invention.

[0034] like Figure 1 As shown, the battery temperature pre-regulation method of this invention, applied to a vehicle, may specifically include:

[0035] S1. Obtain the current temperature of the battery when the vehicle is in navigation mode and located within the target charging area, or when the vehicle is not in navigation mode but located within the target charging area and the battery charge is less than a preset charge threshold.

[0036] S2 adjusts the battery temperature based on the current temperature and a preset temperature range to bring the battery temperature to the preset temperature range before performing the battery charging operation.

[0037] Specifically, the target charging area can be determined based on the location of charging devices such as charging piles and charging stations. For example, the target charging area can be divided with the charging pile as the center and the target distance as the radius, or the target charging area can be based on the area of ​​the charging station itself.

[0038] Taking the charging area as the area corresponding to a charging station as an example, when the vehicle is in navigation mode, the target charging area can be the area of ​​the charging station corresponding to the navigation destination, or the area of ​​the charging station along the navigation route. When the vehicle is in navigation mode, if it is determined that the vehicle is within the target charging area, it is considered to be in an active charging state, indicating a battery charging need. For example, if the user estimates that the current battery level is insufficient to reach the destination based on the target driving range, they will actively charge the battery. In this case, there is no need to judge the battery level; instead, the battery temperature is actively adjusted to bring it to a preset temperature range before charging, improving charging efficiency and shortening charging time.

[0039] When the vehicle is not in navigation mode and is located within the target charging area, the system acquires the battery level and determines if charging is needed. If the battery level is below a preset threshold, charging is considered necessary, and the system proactively adjusts the battery temperature to a preset range before charging, improving charging efficiency and shortening charging time. If the battery level is equal to or greater than the preset threshold, no charging is considered, and the pre-adjustment of battery temperature is not performed. The preset threshold can be set according to actual conditions and is not specifically limited.

[0040] In addition, battery temperature regulation can be achieved through temperature control components installed in the vehicle. These can include PTC heaters, liquid cooling systems, heat pump systems, heat pipe technology, and intelligent thermal management systems, with specific applications chosen based on actual conditions.

[0041] Therefore, this embodiment can automatically determine and adjust the battery temperature when the user navigates to a charging station (target charging area), or when the battery level is below a preset threshold and the user enters an area with a charging station (target charging area), ensuring that the battery is within the optimal temperature range during charging, thereby improving charging efficiency. The preset temperature range can be set based on battery parameters, or it can be set in conjunction with the current ambient temperature to ensure the battery is within the optimal temperature range during charging.

[0042] In one embodiment of the present invention, adjusting the battery temperature based on the current temperature and a preset temperature range includes: obtaining the temperature difference between the current temperature and the preset temperature range; and adjusting the battery temperature based on the temperature difference.

[0043] In other words, the battery temperature is pre-regulated based on the temperature deviation between the current temperature and the preset temperature range. Specifically, when the battery's current temperature is within the preset temperature range, no temperature regulation is performed; when the battery's current temperature is outside the preset temperature range, the temperature difference between the current temperature and the preset temperature range is obtained, and the pre-heating or pre-cooling function is activated based on the temperature difference to adjust the battery temperature to the preset temperature range. This temperature regulation can be achieved through a built-in temperature control device or an external heat / cold source.

[0044] In one embodiment of the present invention, temperature regulation of the battery based on temperature difference includes: cooling the battery when the temperature difference is positive; and heating the battery when the temperature difference is negative.

[0045] In other words, when the battery's current temperature is higher than the preset temperature range, the battery pre-cooling function is activated to cool the battery down, thereby adjusting the battery temperature to the preset temperature range. When the battery's current temperature is lower than the preset temperature range, the battery pre-heating function is activated to heat the battery up, thereby adjusting the battery temperature to the preset temperature range.

[0046] In one embodiment of the present invention, the method of adjusting the battery temperature based on the temperature difference further includes: obtaining the absolute value of the temperature difference; and adjusting the operating parameters of the temperature adjustment based on the absolute value of the temperature difference.

[0047] In other words, the absolute value of the temperature difference is used to determine the magnitude of the temperature difference between the current temperature and the preset temperature range. This allows for dynamic adjustment of the temperature regulation parameters, thereby adjusting the intensity and speed of temperature regulation to ensure that the battery temperature can quickly and accurately reach the preset temperature range. These parameters can include heating power, refrigerant flow rate, valve opening, and other parameters.

[0048] For example, when the battery's current temperature is higher than the preset temperature range, the battery pre-cooling function is activated. Simultaneously, the absolute value of the temperature difference is acquired. If the absolute value of the temperature difference is large, the refrigerant flow rate is increased to accelerate cooling; if the absolute value of the temperature difference is small, cooling is performed according to the preset refrigerant flow rate. Conversely, when the battery's current temperature is lower than the preset temperature range, the battery pre-heating function is activated. Again, the absolute value of the temperature difference is acquired. If the absolute value of the temperature difference is large, the refrigerant flow rate is increased to accelerate heating; if the absolute value of the temperature difference is small, heating is performed according to the preset refrigerant flow rate.

[0049] Understandably, the operating parameters for temperature regulation also have preset parameter ranges. The operating parameters are adjusted within the preset parameter range based on the absolute value of the temperature difference to avoid damage to the battery caused by excessive heating or cooling capacity.

[0050] In addition, during the temperature regulation process of the battery, the intensity and speed of temperature regulation can be dynamically adjusted according to the real-time temperature of the battery, changes in ambient temperature, and preset temperature range to ensure that the battery temperature can quickly and accurately reach the preset temperature range.

[0051] In one embodiment of the present invention, the battery temperature pre-adjustment method further includes: acquiring the ambient temperature; determining a preset temperature range based on the ambient temperature; or, determining a target temperature within the preset temperature range based on the ambient temperature, so as to adjust the battery temperature based on the current temperature and the target temperature.

[0052] In other words, the preset temperature range can be set solely based on battery parameters, or it can be determined in conjunction with the ambient temperature of the battery. For example, if the preset temperature range is determined to be 25℃-28℃ based on battery parameters, and the vehicle is in an environment of -10℃, considering the impact of the external environment on the battery temperature during charging, the preset temperature range can be adjusted upwards accordingly, for example, to 28℃-30℃; if the vehicle is in an environment of 35℃, considering the impact of the external environment on the battery temperature during charging, the preset temperature range can be adjusted downwards accordingly, for example, to 22℃-27℃. Then, battery temperature pre-adjustment is performed based on the adjusted preset temperature range.

[0053] Alternatively, a target temperature within a preset temperature range can be determined based on the ambient temperature, and then the battery temperature can be adjusted based on the current temperature and the target temperature. For example, if the preset temperature range is 25℃-28℃, and the vehicle is in an environment of -15℃, the target temperature is set to 28℃; if the vehicle is in an environment of 35℃, the target temperature is set to 25℃. Then, the battery temperature is adjusted to the target temperature to complete the pre-adjustment of the battery temperature.

[0054] In one embodiment of the present invention, when adjusting the temperature of the battery to a preset temperature range, the battery temperature pre-adjustment method further includes: sending a feedback signal to the vehicle controller.

[0055] In other words, once the battery temperature is adjusted to the preset range, the temperature pre-adjustment process stops, and a feedback signal is sent to the vehicle's controller to indicate that the pre-adjustment is complete. At this point, the vehicle can begin charging to ensure maximum charging efficiency and driving range. Simultaneously, the controller records the data and effects of this temperature adjustment, providing a reference for subsequent optimization and improvement.

[0056] As a specific embodiment of the present invention, such as Figure 2 As shown, the battery temperature pre-conditioning method may include the following steps:

[0057] S101, obtain the vehicle's in-vehicle navigation status and the vehicle's current location.

[0058] S102, Determine whether the in-vehicle navigation is turned on. If yes, proceed to step S103; otherwise, proceed to step S104.

[0059] S103, determine whether the vehicle is located within the target charging area. If yes, proceed to step S107; otherwise, proceed to step S101.

[0060] S104, determine whether the vehicle is located within the target charging area. If yes, proceed to step S105. If no, proceed to step S101.

[0061] S105, obtains the battery power.

[0062] S106, determine whether the battery level is less than a preset power threshold. If yes, proceed to step S107; otherwise, proceed to step S101.

[0063] S107, obtain the current temperature of the battery.

[0064] S108, determine whether the current temperature is within the preset temperature range. If yes, proceed to step S109; otherwise, proceed to step S110.

[0065] S109: Determine that the battery temperature is at its optimal operating state and begin charging the battery.

[0066] S110, determine whether the current temperature is higher than the preset temperature range. If yes, proceed to step S111; otherwise, proceed to step S112.

[0067] S111, perform a cooling operation on the battery temperature. Then return to step S107.

[0068] S112, heat the battery to adjust its temperature. Then return to step S107.

[0069] Therefore, this embodiment allows for pre-adjustment of the battery temperature before charging, ensuring battery charging efficiency and offering the following advantages:

[0070] 1. Improved charging efficiency: By preheating or precooling the battery to its optimal charging temperature range, charging time can be significantly shortened, improving charging efficiency. This not only increases the vehicle's driving range but also reduces user waiting time during charging, enhancing the user experience.

[0071] 2. Alleviating range anxiety: In cold or hot environments, improving charging efficiency can increase the actual driving range of electric vehicles, effectively alleviating users' range anxiety. Users can use electric vehicles for long-distance travel with greater peace of mind and enjoy a more convenient and comfortable travel experience.

[0072] 3. Intelligent Operation: Based on navigation and battery information, the system automatically determines whether to activate the battery temperature pre-regulation function, eliminating the need for manual operation and achieving intelligent management. This not only reduces the difficulty and complexity of operation for users but also improves the stability and reliability of the system.

[0073] 4. Energy conservation and emission reduction: By optimizing charging efficiency, energy consumption and emissions of electric vehicles during the charging process are reduced, meeting the requirements of environmental protection and sustainable development. At the same time, reducing charging time also reduces the load pressure on the power grid, improving the grid's operating efficiency and stability.

[0074] In summary, the battery temperature pre-adjustment method according to embodiments of the present invention acquires the current temperature of the battery when the vehicle is in navigation mode and located within the target charging area, or when the vehicle is not in navigation mode but located within the target charging area and the battery charge is less than a preset charge threshold. Based on the current temperature and a preset temperature range, the battery temperature is adjusted to within the preset temperature range before the battery charging operation is performed. Therefore, this method automatically determines and adjusts the battery temperature to the preset temperature range when the vehicle is in navigation mode and located within the target charging area, or when the vehicle is not in navigation mode but located within the target charging area and the battery charge is low, so that the battery is in the optimal temperature range during charging, thereby improving charging efficiency.

[0075] Corresponding to the above embodiments, the present invention also proposes a controller.

[0076] like Figure 3As shown, the controller 100 of this embodiment includes a memory 110, a processor 120, and a battery temperature pre-adjustment program stored in the memory 110 and executable on the processor 120. When the processor 120 executes the battery temperature pre-adjustment program, it implements the battery temperature pre-adjustment method described above.

[0077] According to the controller of the present invention, when the processor executes the battery temperature pre-adjustment program, the above-described battery temperature pre-adjustment method is implemented. Based on the above-described battery temperature pre-adjustment method, the battery temperature can be automatically determined and adjusted to a preset temperature range when the vehicle is in navigation mode and located within the target charging area, or when the vehicle is not in navigation mode, located within the target charging area and the battery charge is low, so as to ensure that the battery is in the optimal temperature range during charging, thereby improving charging efficiency.

[0078] Corresponding to the above embodiments, the present invention also proposes a computer-readable storage medium.

[0079] The computer-readable storage medium of this invention stores a battery temperature pre-regulation program, which, when executed by a processor, implements the battery temperature pre-regulation method described above.

[0080] According to an embodiment of the present invention, a computer-readable storage medium implements the above-described battery temperature pre-adjustment method when the battery temperature pre-adjustment program is executed by a processor.

[0088] According to one embodiment of the present invention, when adjusting the temperature of the battery to a preset temperature range, the adjustment module 20 is further configured to: send a feedback signal to the vehicle controller.

[0089] As a specific embodiment of this application, the battery temperature pre-regulation device may include the following modules:

[0091] 2) Navigation and Location Recognition Module: This module receives navigation commands from the user and uses GPS or other positioning technologies to identify whether the vehicle has entered a preset charging station area. Its close integration with the in-vehicle navigation system enables the system to obtain the vehicle's driving route and location information in real time, providing accurate navigation support for battery temperature pre-adjustment.

[0092] 3) Battery Level Monitoring Module: This module monitors the battery's power status in real time and triggers the battery temperature pre-regulation function when the power level falls below a preset threshold.

[0095] It should be noted that for details not disclosed in the battery temperature pre-adjustment device of the present invention, please refer to the details disclosed in the battery temperature pre-adjustment method of the above embodiments of the present invention, which will not be repeated here.

[0096] According to an embodiment of the present invention, a battery temperature pre-regulation device acquires the current battery temperature by an acquisition module when the vehicle is in navigation mode and located in a target charging area, or when the vehicle is not in navigation mode but located in a target charging area and the battery charge is less than a preset charge threshold. An adjustment module then adjusts the battery temperature based on the current temperature and a preset temperature range to bring the battery temperature to the preset temperature range before performing battery charging. Therefore, when the vehicle is in navigation mode and located in a target charging area, or when the vehicle is not in navigation mode but located in a target charging area and the battery charge is low, the device automatically determines and adjusts the battery temperature to the preset temperature range to ensure optimal temperature during battery charging, thereby improving charging efficiency.
