Description

Technical Field

[0001] The present disclosure relates to the field of vehicle control, and in particular to a vehicle charging control method, an electronic device, and a vehicle. Background Art

[0002] With the rapid development of vehicle technology, vehicles have become an important means of transportation in people's daily lives. In the field of new energy vehicles, power batteries are core components, and their lifespan directly affects the performance and economy of the vehicle.

[0003] When the vehicle is currently charging, if the battery temperature is high, charging directly at this time will accelerate the chemical reaction of the battery, causing a sharp drop in lifespan, and thus reducing vehicle performance. Summary of the Invention

[0004] In view of this, the purpose of the present disclosure is to propose a vehicle charging control method, electronic equipment and vehicle to solve the problem that when the vehicle is currently charging, if the vehicle battery temperature is high, direct charging at this time will cause the chemical reaction of the battery to accelerate, resulting in a sharp decrease in lifespan, and thus a decrease in vehicle performance.

[0005] Based on the above objectives, a first aspect of the present disclosure provides a vehicle charging control method, the method comprising:

[0006] Determining that the vehicle is connected to a charging pile and that a battery temperature of the vehicle battery is greater than a preset temperature threshold, obtaining the vehicle's current power level and available charging time, and determining a natural cooling available time based on the vehicle's current power level and the available charging time;

[0007] determining a target cooling strategy based on the available natural cooling time, and cooling the vehicle battery using the target cooling strategy;

[0008] Determine that the battery temperature of the vehicle battery is less than or equal to a preset temperature threshold, and charge the vehicle through the charging pile.

[0009] Specifically, determining a target cooling strategy based on the available natural cooling time includes:

[0010] comparing the available natural cooling time with a preset time threshold;

[0011] In response to the available natural cooling time being less than or equal to a preset time threshold, determining that the target cooling strategy is active cooling, wherein the active cooling is cooling using a thermal management system; or

[0012] In response to the available natural cooling time being greater than a preset time threshold, the ambient temperature is acquired, and a target cooling strategy is determined according to the battery temperature and the ambient temperature.

[0013] With this solution, if the available natural cooling time is determined to be less than or equal to the preset time threshold, active cooling alone can be used to lower the battery temperature. However, if natural cooling is possible, the ambient temperature is obtained to avoid the risk of failing to lower the battery temperature to the preset threshold due to high ambient temperatures. This improves the battery cooling success rate, allowing the vehicle to charge as quickly as possible to meet the user's charging needs.

[0014] Specifically, determining a target cooling strategy according to the battery temperature and the ambient temperature includes:

[0015] In response to the battery temperature being greater than the ambient temperature, determining the target cooling strategy to be natural cooling; or,

[0016] In response to the battery temperature being less than or equal to the ambient temperature, determining the target cooling strategy to be active cooling.

[0017] Specifically, after determining that the target cooling strategy is natural cooling, the following steps are further included:

[0018] Use natural cooling to cool the vehicle battery and record the cooling time;

[0019] In response to the cooling time being equal to the available natural cooling time, obtaining a current battery temperature;

[0020] It is determined that the current battery temperature is greater than a preset temperature threshold, and the vehicle battery is cooled using active cooling until the battery temperature is less than or equal to the preset temperature threshold.

[0021] The above solution compares the battery temperature with the ambient temperature. If the battery temperature is less than or equal to the ambient temperature, only active cooling can be used for cooling. Meanwhile, if the battery temperature is greater than the ambient temperature, after the available time of natural cooling using ambient heat dissipation is reached, it is determined whether the battery temperature is less than or equal to a preset temperature threshold, and then whether active cooling is still required. This combination of natural and active cooling fully utilizes the environment for natural cooling, reduces energy consumption, ensures that the battery temperature meets charging conditions, and extends battery life.

[0022] Specifically, obtaining the current battery level of the vehicle and the available charging time, and determining the available natural cooling time according to the current battery level of the vehicle and the available charging time, includes:

[0023] Obtain the current battery level of the vehicle and the available charging time, and determine the charging time based on the current battery level of the vehicle;

[0024] obtaining a cooling efficiency of a vehicle thermal management system, and determining an active cooling time required to cool the battery from a temperature to a preset temperature threshold based on the cooling efficiency;

[0025] The available natural cooling time is determined according to the available charging time, the charging duration, and the active cooling time.

[0026] Through the above solution, when determining the available time of natural cooling, the active cooling time can be maximized. After determining the available time of natural cooling, even if a combination of natural cooling and active cooling is required, it can still be ensured that the battery is charged while the user is using the car, thereby improving the user's car experience.

[0027] Specifically, determining the charging time according to the current power level of the vehicle includes:

[0028] Obtaining the maximum output power of the charging pile, and determining the target charging power based on the maximum output power of the charging pile and the current power of the vehicle;

[0029] The target charging power is determined according to the current power of the vehicle, and the target charging power is ratioed to obtain the charging time.

[0030] Specifically, obtaining the maximum output power of the charging pile and determining the target charging power according to the maximum output power of the charging pile and the current power of the vehicle include:

[0031] Obtaining a vehicle battery health, determining a maximum allowable charging current for the vehicle based on the vehicle battery health, the current charge level of the vehicle, and the battery temperature, and determining a maximum allowable charging power corresponding to the maximum allowable charging current of the vehicle;

[0032] Get the maximum output power of the charging pile;

[0033] In response to the maximum output power of the charging pile being less than the maximum allowable charging power, determining the target charging power to be the maximum output power of the charging pile; or,

[0034] In response to the maximum output power of the charging pile being greater than or equal to the maximum allowable charging power, the target charging power is determined to be the maximum allowable charging power.

[0035] The above solution limits the charging power when charging a vehicle using a charging station. If the maximum output power of the charging station exceeds the vehicle's maximum allowable charging power, the vehicle's maximum allowable charging power is used as the target charging power. This prevents battery damage caused by excessive charging power and extends battery life.

[0036] Specifically, obtaining the current battery level of the vehicle and the available charging time, and determining the available natural cooling time according to the current battery level of the vehicle and the available charging time, includes:

[0037] In response to the current battery level of the vehicle being less than a preset battery level threshold, charging the vehicle using a charging pile until the battery level of the vehicle is equal to the preset battery level threshold; or

[0038] In response to the current power level of the vehicle being greater than or equal to a preset power level threshold, the available charging time is acquired, and the available natural cooling time is determined according to the current power level of the vehicle and the available charging time.

[0039] Through the above solution, when the vehicle's battery level is already low, in order to avoid the need for active cooling using the vehicle's thermal management system, the low battery level causes deep discharge of the vehicle, which affects the battery life. Therefore, the vehicle battery is charged first, and then the subsequent cooling judgment logic is executed to avoid deep discharge damage to the vehicle battery.

[0040] Based on the same inventive concept, the second aspect of the present disclosure provides a vehicle charging control device, comprising:

[0041] a natural cooling available time determination module configured to determine that a vehicle is connected to a charging pile and that a battery temperature of the vehicle battery is greater than a preset temperature threshold, obtain the vehicle's current power level and the available charging time, and determine the natural cooling available time based on the vehicle's current power level and the available charging time;

[0042] a cooling processing module configured to determine a target cooling strategy based on the available natural cooling time, and perform a cooling process on the vehicle battery using the target cooling strategy;

[0043] The charging module is configured to determine that the battery temperature of the vehicle battery is less than or equal to a preset temperature threshold and charge the vehicle through the charging pile.

[0044] Based on the same inventive concept, the third aspect of the present disclosure proposes an electronic device, comprising a memory, a processor, and a computer program stored on the memory and executable by the processor, wherein the processor implements the vehicle charging control method as described above when executing the computer program.

[0045] Based on the same inventive concept, a fourth aspect of the present disclosure proposes a non-transitory computer-readable storage medium, which stores computer instructions for causing a computer to execute the vehicle charging control method as described above.

[0046] Based on the same inventive concept, the fifth aspect of the present disclosure provides a vehicle, comprising the vehicle charging control device described in the second aspect, the electronic device described in the third aspect, or the storage medium described in the fourth aspect.

[0047] As can be seen from the foregoing, the present disclosure provides a vehicle charging control method, electronic device, and vehicle. The method determines that a vehicle is connected to a charging station and the battery temperature of the vehicle battery is greater than a preset temperature threshold, indicating that the vehicle needs to be charged. However, due to the high battery temperature, to ensure battery life, the battery should be cooled before charging. The method obtains the vehicle's current battery level and available charging time, and determines a natural cooling time based on the current vehicle level and the available charging time, where the natural cooling time represents the time allowed for natural cooling by the environment. A target cooling strategy is determined based on the available natural cooling time, and the vehicle battery is cooled using the target cooling strategy. Based on the available natural cooling time, a target cooling strategy is selected that is appropriate for the current environment and vehicle battery status, and the vehicle battery is cooled using the target cooling strategy. While achieving battery cooling, the method fully utilizes natural cooling from the environment, avoiding reliance solely on the vehicle's thermal management system for active cooling, which could result in excessive vehicle energy consumption. When the vehicle battery temperature is determined to have dropped below the preset temperature threshold, the method indicates that the battery temperature has a minimal impact on battery life during vehicle charging. Charging the vehicle through the charging station extends battery life while reducing cooling energy consumption. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] In order to make the objectives, technical solutions and advantages of the present disclosure more clearly understood, the present disclosure is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0053] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present disclosure should have the usual meanings understood by people with ordinary skills in the field to which the present disclosure belongs. The "first", "second" and similar words used in the embodiments of the present disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components.

When the absolute position of the described object changes, the relative position relationship may also change accordingly.

[0054] The terms used in this disclosure are explained as follows:

[0055] SOC: State-of-Charge (SOC) refers to the battery's current charge level, indicating the proportion of electrical energy stored in the battery to its total capacity. It is similar to the amount of fuel in a tank, showing the percentage of remaining battery power.

[0056] BMS: Battery management system (BMS) is an indispensable component of electric vehicles. It is the hub for managing and monitoring power batteries. It manages, maintains and monitors each battery module, and is responsible for preventing battery overcharge and over-discharge, extending battery life, and helping batteries operate normally.

[0057] SOH: State of health (SOH) is often used to indicate the remaining life of a battery. Battery operating conditions are complex, and multiple factors such as temperature and charge / discharge rate can affect the health of individual cells. Inconsistencies in individual cells can also affect the life of the battery pack.

[0059] APP: Application (APP). In a narrow sense, APP refers to third-party applications for smartphones. In a broad sense, APP refers to all client software, and now mostly refers to mobile applications.

[0060] With the rapid development of vehicle technology, vehicles have become an important means of transportation in people's daily lives. In the field of new energy vehicles, power batteries are core components, and their lifespan directly affects the performance and economy of the vehicle.

[0061] When the vehicle is currently charging, if the battery temperature is high, charging directly at this time will accelerate the chemical reaction of the battery, causing a sharp drop in lifespan, and thus reducing vehicle performance.

[0062] At the same time, thermal management systems are typically used to cool vehicle batteries. However, existing thermal management strategies often fail to fully utilize natural cooling from the environment, resulting in high energy consumption.

[0063] That is to say, when the vehicle is currently charging, if the vehicle battery temperature is high, directly charging at this time will accelerate the chemical reaction of the battery, resulting in a sharp decrease in lifespan and vehicle performance. If the battery is only cooled by the thermal management system, the vehicle energy consumption is high. Therefore, this embodiment proposes a vehicle charging control method, such as Figure 1 As shown, the method includes:

[0064] Step 101: Determine whether the vehicle is connected to a charging pile and the battery temperature of the vehicle battery is greater than a preset temperature threshold, obtain the current battery level of the vehicle and the available charging time, and determine the available natural cooling time based on the current battery level of the vehicle and the available charging time.

[0065] In a specific implementation, when a vehicle is connected to a charging station, indicating that a user wants to charge the vehicle via the charging station, the battery temperature of the vehicle battery is obtained and compared with a preset temperature threshold, wherein the preset temperature threshold is the maximum battery temperature allowed to ensure battery life when the vehicle is charging.

[0066] If the battery temperature is less than or equal to the preset temperature threshold, it means that charging the vehicle will not have a significant impact on the battery life, so the charging process can be directly entered.

[0067] If the battery temperature is higher than the preset threshold, it indicates that the battery temperature is too high. Directly charging the vehicle will accelerate the chemical reaction in the vehicle battery, causing a sharp decrease in battery life. Therefore, the vehicle battery must be cooled down until it reaches the preset threshold before charging the vehicle using a charging station.

[0068] For example, the preset temperature threshold is 40°C, meaning that the maximum battery temperature allowed during vehicle charging to ensure battery life is 40°C. Furthermore, when the battery temperature is less than or equal to 40°C, the vehicle can be charged directly. When the battery temperature is greater than 40°C, direct charging will result in a reduced battery life due to the high battery temperature. Therefore, the vehicle battery must be cooled to reduce the battery temperature to less than or equal to 40°C.

[0069] Obtain the vehicle's current battery level and available charging time, and determine the available natural cooling time based on the current battery level and available charging time. The available charging time represents the time from the current time until the next time the user uses the vehicle, i.e., the maximum time available for vehicle charging. The available natural cooling time represents the time allowed for natural cooling by the environment.

[0070] In this embodiment, the time corresponding to the user's next car use can be determined by a pre-set car use time point or by the itinerary information set by the user, specifically including:

[0071] When determining the time corresponding to the user's next use of the car through a pre-set car use time point, the user is supported to set multiple car use time points, and the car use time point after the current time and closest to the current time is used as the target car use time point.

[0072] For example, the user pre-sets multiple car usage time points, namely 18:00 and 8:00, and the current time is 12:00, so the target car usage time point is determined to be 18:00, that is, the user's next car usage time is determined to be 18:00.

[0073] When determining the time of the user's next ride based on the trip information set by the user, the system can synchronize with the calendar of the user's electronic device via an API, automatically extract the estimated departure time from the most recent trip, and then use the estimated departure time as the user's next ride time. The user's electronic device includes at least one of the following: a mobile phone, a computer, a tablet, a watch, a bracelet, etc.

[0074] In this embodiment, the user may need to change the car use time due to reasons such as sudden emergencies. Therefore, the user is supported to remotely modify the car use time through the mobile phone APP or voice assistant to ensure that the sudden trip adjustment can take effect immediately.

[0075] Step 102 : determining a target cooling strategy based on the available natural cooling time, and cooling the vehicle battery using the target cooling strategy.

[0076] In a specific implementation, a corresponding target cooling strategy is determined based on the determined available natural cooling time, and the vehicle battery is cooled using the target cooling strategy. The target cooling strategy represents a specific method for cooling the vehicle battery, and the target cooling strategy includes active cooling and natural cooling.

[0077] In this embodiment, active cooling refers to cooling through the use of a thermal management system. For example, during fast charging, the optimal battery temperature is approximately 40°C. At this temperature, the lithium-ion battery's internal resistance is minimized, enabling extremely fast charging and minimal losses. Furthermore, the battery generates heat during charging, and the thermal management system must promptly dissipate this heat away from the battery pack to maintain the optimal charging temperature. If this temperature is exceeded, the charging current must be reduced to prevent irreversible battery degradation.

[0078] Natural cooling means lowering the battery temperature through environmental heat dissipation. It can be understood that when the vehicle battery is cooled by natural cooling, the battery temperature of the vehicle battery is reduced to the same as the ambient temperature because it relies solely on natural heat dissipation.

[0079] Step 103 : Determine whether the battery temperature of the vehicle battery is less than or equal to a preset temperature threshold, and charge the vehicle through the charging pile.

[0080] In specific implementations, a targeted cooling control strategy is used to cool the vehicle battery and monitor the battery temperature in real time until the battery temperature is less than or equal to a preset temperature threshold. This indicates that charging the battery will not significantly impact the battery life. Therefore, when the battery temperature is determined to be less than or equal to the preset temperature threshold, the vehicle is charged using a charging station.

[0081] Through the above scheme, it is determined that a vehicle is connected to a charging station and the battery temperature of the vehicle battery is greater than a preset temperature threshold. This indicates that the vehicle needs to be charged. However, due to the high battery temperature, to preserve battery life, the battery should be cooled before charging. The vehicle's current battery level and available charging time are obtained. Based on the current vehicle level and available charging time, a natural cooling time is determined. The natural cooling time represents the time allowed for natural cooling by the environment. A target cooling strategy is determined based on the available natural cooling time, and the vehicle battery is cooled using the target cooling strategy. Based on the available natural cooling time, a target cooling strategy is selected that is appropriate for the current environment and vehicle battery status. The target cooling strategy is then used to cool the vehicle battery. While achieving battery cooling, this strategy fully utilizes natural cooling from the environment, avoiding reliance solely on the vehicle's thermal management system for active cooling, which could result in excessive vehicle energy consumption. When the vehicle battery temperature is determined to have fallen below the preset temperature threshold, this indicates that the battery temperature has a minimal impact on battery life during vehicle charging. Charging the vehicle through the charging station extends battery life while reducing cooling energy consumption.

[0082] In some embodiments, since the natural cooling available time represents the time allowed for cooling the vehicle battery by natural cooling, the corresponding target cooling strategy is determined by determining the length of the natural cooling available time. That is, determining the target cooling strategy based on the natural cooling available time in step 102 specifically includes:

[0083] Step 1021, comparing the natural cooling available time with a preset time threshold;

[0084] Step 1022: In response to the available natural cooling time being less than or equal to a preset time threshold, determining that the target cooling strategy is active cooling, wherein the active cooling is cooling using a thermal management system; or

[0085] Step 1023 : In response to the available natural cooling time being greater than a preset time threshold, obtaining the ambient temperature, and determining a target cooling strategy according to the battery temperature and the ambient temperature.

[0086] In specific implementation, after determining the available natural cooling time, the available natural cooling time is compared with a preset time threshold. In this embodiment, the preset time threshold is preferably 0.

[0087] If the available natural cooling time is less than or equal to the preset time threshold, and the preset time threshold is 0, then no natural cooling time is available, meaning that the vehicle battery temperature cannot be lowered through natural heat dissipation from the environment. Therefore, the target cooling strategy is determined to be active cooling, which uses the thermal management system for cooling.

[0088] If the available natural cooling time exceeds the preset time threshold, it indicates that the vehicle battery temperature can be lowered by natural heat dissipation from the environment. In the above embodiment, it has been explained that when the vehicle battery is cooled by natural cooling, the battery temperature of the vehicle battery can be reduced to the same as the ambient temperature due to the sole use of natural heat dissipation.

[0089] Therefore, when the available natural cooling time is greater than the preset time threshold, it is also necessary to obtain the ambient temperature, and then further determine the corresponding target cooling strategy based on the ambient temperature and battery temperature to avoid the risk of not being able to lower the battery temperature to the preset temperature threshold due to high ambient temperature.

[0090] With this solution, if the available natural cooling time is determined to be less than or equal to the preset time threshold, active cooling alone can be used to lower the battery temperature. However, if natural cooling is possible, the ambient temperature is obtained to avoid the risk of failing to lower the battery temperature to the preset threshold due to high ambient temperatures. This improves the battery cooling success rate, allowing the vehicle to charge as quickly as possible to meet the user's charging needs.

[0091] In some embodiments, the battery temperature is compared with the ambient temperature to determine whether natural heat dissipation can be used to cool the battery. That is, in step 1023, a target cooling strategy is determined based on the battery temperature and the ambient temperature, specifically including:

[0092] Step 10231: In response to the battery temperature being greater than the ambient temperature, determining that the target cooling strategy is natural cooling; or,

[0093] Step 10232: In response to the battery temperature being less than or equal to the ambient temperature, determining that the target cooling strategy is active cooling.

[0094] During specific implementation, the ambient temperature of the vehicle environment is obtained, and the battery temperature is compared with the ambient temperature.

[0095] If the battery temperature is higher than the ambient temperature, the target cooling strategy is determined to be natural cooling. Because the battery temperature is higher than the ambient temperature, natural cooling from the ambient environment can be used to control the cooling and heat dissipation of the vehicle battery.

[0096] In this embodiment, since heat is dissipated through natural cooling from the environment, the vehicle battery temperature is cooled to the ambient temperature at the lowest possible temperature. At the same time, because different ambient temperatures correspond to different heat dissipation efficiencies, and ambient heat dissipation is significantly affected by the weather, it is impossible to accurately estimate when the vehicle battery temperature will reach the preset temperature threshold. Therefore, the cooling time of natural cooling can be measured to determine whether active cooling is still needed to assist in heat dissipation. That is, after determining that the target cooling strategy is natural cooling, the following steps are specifically included:

[0097] Step A: Cooling the vehicle battery using natural cooling and recording the cooling time;

[0098] Step B: in response to the cooling time being equal to the available natural cooling time, obtaining a current battery temperature;

[0099] Step C: determining that the current battery temperature is greater than a preset temperature threshold, and cooling the vehicle battery using active cooling until the battery temperature is less than or equal to the preset temperature threshold.

[0100] In specific implementation, after determining that the target cooling strategy is natural cooling, the vehicle battery is cooled using natural cooling, that is, the vehicle battery is naturally cooled by the environment. At the same time, the cooling time is recorded when natural cooling begins.

[0101] Monitor the recorded cooling time in real time. If the cooling time is equal to the natural cooling available time, it means that the current natural cooling time has reached the previously calculated natural cooling available time. Obtain the battery temperature at this time, which is the current battery temperature.

[0102] Compare the current battery temperature with a preset temperature threshold. That is, when using natural cooling to cool the vehicle battery, determine whether the battery temperature has dropped to the preset temperature threshold after the time corresponding to the available natural cooling time has passed, that is, whether it has dropped to the maximum temperature value allowed for charging.

[0103] If the current battery temperature is greater than the preset temperature threshold, it means that natural cooling alone cannot cool the vehicle battery to the maximum temperature allowed for charging, which cannot meet user needs. At this time, active cooling should be used to further cool the vehicle battery until the battery temperature is less than or equal to the preset temperature threshold.

[0104] That is, when using natural cooling to cool the vehicle battery, the maximum cooling time is the natural cooling available time. If the vehicle temperature has not dropped to the maximum allowable charging temperature after the natural cooling available time, active cooling will continue until the battery temperature is below or equal to the preset temperature threshold.

[0105] For example, if the battery temperature is 60°C, the ambient temperature is 50°C, and the preset temperature threshold is 40°C, then the target cooling strategy is determined to be natural cooling. The available natural cooling time is determined to be 30 minutes. After 30 minutes of natural cooling, the current battery temperature is obtained. If the current battery temperature is 45°C, still greater than the preset temperature threshold, active cooling is continued.

[0106] If the current battery temperature is less than or equal to the ambient temperature, and based on the above, it can be known that the current battery temperature is greater than the preset temperature threshold, then it can be known that the ambient temperature is greater than the preset temperature threshold, that is, the relationship between the ambient temperature, the preset temperature threshold and the current battery temperature is that the ambient temperature is greater than the current battery temperature and the current battery temperature is greater than the preset temperature threshold.

[0107] At the same time, due to the natural heat dissipation from the environment, the vehicle battery temperature is now cooled to the ambient temperature at the lowest. However, the ambient temperature is greater than the preset temperature threshold, so natural cooling cannot reduce the current battery temperature to below the preset temperature threshold. In this case, only active cooling can be used for cooling, which determines the target cooling strategy as active cooling.

[0108] For example, the battery temperature is 50°C, the ambient temperature is 60°C, and the preset temperature threshold is 40°C. At this time, it is impossible to cool the battery temperature to the preset temperature threshold by natural heat dissipation. Therefore, the target cooling strategy is determined to be active cooling.

[0109] The above solution compares the battery temperature with the ambient temperature. If the battery temperature is less than or equal to the ambient temperature, only active cooling can be used for cooling. Meanwhile, if the battery temperature is greater than the ambient temperature, after the available time of natural cooling using ambient heat dissipation is reached, it is determined whether the battery temperature is less than or equal to a preset temperature threshold, and then whether active cooling is still required. This combination of natural and active cooling fully utilizes the environment for natural cooling, reduces energy consumption, ensures that the battery temperature meets charging conditions, and extends battery life.

[0110] In some embodiments, because the ambient temperature is an uncontrollable factor, when natural cooling is used, the battery temperature may still not drop to the maximum charging temperature allowed after natural cooling, that is, active cooling is still required for cooling.

[0111] Therefore, when determining the available natural cooling time, the active cooling time required to cool the battery temperature to a preset temperature threshold when active cooling is used can be eliminated, that is, the active cooling time can be maximized. After determining the available natural cooling time, even if a combination of natural cooling and active cooling is required, the battery can still be charged while the user is using the vehicle. That is, in step 101, the current vehicle power level and the available charging time are obtained, and the available natural cooling time is determined based on the current vehicle power level and the available charging time, specifically including:

[0112] Step 1011, obtaining the current battery level of the vehicle and the available charging time, and determining the charging time according to the current battery level of the vehicle;

[0113] Step 1012 , obtaining a cooling efficiency of the vehicle thermal management system, and determining an active cooling time required to cool the battery temperature to a preset temperature threshold based on the cooling efficiency;

[0114] Step 1013: Determine the available natural cooling time according to the available charging time, the charging duration, and the active cooling time.

[0115] During specific implementation, the current power level of the vehicle and the available charging time are obtained, and the charging time is determined based on the current power level of the vehicle. The charging time represents the total charging time required to charge the vehicle from the current power level to the full power level.

[0116] Obtain the cooling efficiency of the vehicle's thermal management system. This efficiency represents the rate at which the vehicle battery temperature decreases per hour when the vehicle thermal management system is used to cool the vehicle battery. Based on this efficiency, determine the active cooling time required to cool the battery temperature to a preset temperature threshold.

[0117] The available time for natural cooling is determined based on the available time for charging, the charging duration, and the active cooling time. The available time for natural cooling is determined in the following manner:

[0118] The charging time and the active cooling time are added together to obtain the sum value. The available charging time is subtracted from the sum value to obtain the available natural cooling time.

[0119] Through the above solution, when determining the available time of natural cooling, the active cooling time can be maximized. After determining the available time of natural cooling, even if a combination of natural cooling and active cooling is required, it can still be ensured that the battery is charged while the user is using the car, thereby improving the user's car experience.

[0120] In some embodiments, the process of determining the charging time based on the current power level of the vehicle specifically includes:

[0121] Step 10A: Obtain the maximum output power of the charging pile, and determine the target charging power according to the maximum output power of the charging pile and the current power of the vehicle.

[0122] Step 10B: determining a target charging power according to the current power of the vehicle, performing ratio processing on the target charging power and the target charging power to obtain a charging time.

[0123] In specific implementation, the maximum output power of the charging pile is obtained, and the target charging power is determined according to the maximum output power of the charging pile and the current power of the vehicle, wherein the target charging power represents the charging power adopted when the vehicle is charging.

[0124] The target charging capacity is determined based on the vehicle's current battery level. The target charging capacity represents the total amount of energy required to charge the vehicle's battery. Specifically, the target charging capacity is the difference between the vehicle's current battery level and the full battery level. For example, if the vehicle's current battery level is 40% and the full battery level is 100%, the target charging capacity is determined to be 60%.

[0125] The determined target charging power is ratioed to the target charging power to obtain a charging duration, wherein the charging duration represents the corresponding charging time when the vehicle charging power reaches the target charging power.

[0126] In this embodiment, the specific method of determining the target charging power based on the maximum output power of the charging pile and the current power of the vehicle includes:

[0127] Step a: obtaining the vehicle battery health, determining the vehicle's maximum allowable charging current based on the vehicle health, the vehicle's current battery level, and the battery temperature, and determining the maximum allowable charging power corresponding to the vehicle's maximum allowable charging current;

[0128] Step b, obtaining the maximum output power of the charging pile;

[0129] Step c: in response to the maximum output power of the charging pile being less than the maximum allowable charging power, determining the target charging power to be the maximum output power of the charging pile; or

[0130] Step d: In response to the maximum output power of the charging pile being greater than or equal to the maximum allowable charging power, determining the target charging power to be the maximum allowable charging power.

[0131] In specific implementations, the vehicle battery health, also known as the battery status health, is obtained. The vehicle battery health is a key parameter in the battery management system, used to monitor the health of the battery, including the remaining capacity and life of the battery.

[0132] The maximum allowable charging current of the vehicle is determined based on the vehicle battery health, the current vehicle charge, and the battery temperature. Specifically, a database may be searched based on the vehicle battery health, the current vehicle charge, and the battery temperature to determine the corresponding maximum allowable charging current of the vehicle. The database stores a correspondence between the vehicle battery health, the current vehicle charge, and the battery temperature, and the maximum allowable charging current of the vehicle. The correspondence may be in the form of at least one of the following: a relationship table, a function relationship, a curve relationship, a key-value pair relationship, and a bar chart relationship.

[0133] In this embodiment, the maximum allowable charging current of the vehicle represents the maximum value of the charging current allowed when the vehicle is charged, that is, it is the upper limit of the charging current allowed when the vehicle battery is charged.

[0134] The maximum allowable charging power corresponding to the maximum allowable charging current of the vehicle is determined, and the maximum output power of the charging pile is obtained. The maximum allowable charging power is compared with the maximum output power of the charging pile to obtain a comparison result.

[0135] If the comparison result is that the maximum output power of the charging pile is less than the maximum allowable charging power, the target charging power is determined to be the maximum output power of the charging pile. That is, when the charging pile is used to charge the vehicle battery at this time, the charging power is the maximum output power of the charging pile.

[0136] If the comparison result is that the maximum output power of the charging pile is greater than or equal to the maximum allowable charging power, the target charging power is determined to be the maximum allowable charging power. That is, when the charging pile is used to charge the vehicle battery, the charging power is the maximum allowable charging power.

[0137] The above solution limits the charging power when charging a vehicle using a charging station. If the maximum output power of the charging station exceeds the vehicle's maximum allowable charging power, the vehicle's maximum allowable charging power is used as the target charging power. This prevents battery damage caused by excessive charging power and extends battery life.

[0138] In some embodiments, before cooling the vehicle battery, it is first determined whether the vehicle battery is sufficiently charged to avoid deep discharge of the vehicle when active cooling is required using the vehicle thermal management system, which may affect the battery life. That is, in step 101, the current battery level of the vehicle and the available charging time are obtained, and the available natural cooling time is determined based on the current battery level of the vehicle and the available charging time, which specifically includes:

[0139] Step 101A: In response to the current battery level of the vehicle being less than a preset battery level threshold, the vehicle is charged using a charging pile until the battery level of the vehicle is equal to the preset battery level threshold; or

[0140] Step 101B: in response to the current power level of the vehicle being greater than or equal to a preset power level threshold, obtain the available charging time, and determine the available natural cooling time based on the current power level of the vehicle and the available charging time.

[0141] During specific implementation, the current battery level of the vehicle is obtained. If the current battery level of the vehicle is less than a preset battery threshold, it means that the vehicle battery level is too low. The vehicle should be preliminarily charged until the vehicle battery level is equal to the preset battery threshold. Then, the available charging time is obtained, and the available natural cooling time is determined based on the current battery level of the vehicle and the available charging time.

[0142] If the current battery level of the vehicle is greater than or equal to a preset battery level threshold, the available charging time can be directly obtained, and then the available natural cooling time can be determined based on the current battery level of the vehicle and the obtained available charging time.

[0143] For example, the preset power threshold is 20%, and the current power of the vehicle is 10%. At this time, the current power of the vehicle is too low. The vehicle should be charged to 20% first, and then the vehicle battery should be cooled until it drops to the preset temperature threshold before charging.

[0144] Through the above solution, when the vehicle's battery level is already low, in order to avoid the need for active cooling using the vehicle's thermal management system, the low battery level causes deep discharge of the vehicle, which affects the battery life. Therefore, the vehicle battery is charged first, and then the subsequent cooling judgment logic is executed to avoid deep discharge damage to the vehicle battery.

[0145] Based on the same inventive concept, another embodiment of the present disclosure provides a vehicle charging control method, the method specifically comprising:

[0146] Step 201: Calculate user available time.

[0147] In specific implementations, the user's available time, or charging time in the aforementioned embodiment, is calculated based on the current time and the user's preset next vehicle use time. Multiple vehicle use time points can be set, and the system automatically allocates charging windows to ensure that the battery condition meets the required level before each trip. For example, the multiple vehicle use time points are 6:00 PM today and 8:00 AM tomorrow.

[0148] In this embodiment, the system can also synchronize with the user's mobile phone / computer calendar through the API to automatically extract the estimated departure time of the most recent trip (user authorization is required). At the same time, users can remotely modify the car usage time through the mobile phone app or voice assistant to ensure that sudden trip adjustments can take effect immediately.

[0149] Step 202: Obtain charging parameters.

[0150] In practice, the vehicle communicates with the charging station to obtain the maximum output power of the charging station. The BMS (Battery Management System) calculates the time required to fully charge (i.e., the charging duration in the above embodiment) based on the current battery status (such as SOC and health) and the maximum output power of the charging station.

[0151] Based on the thermal management system's cooling capacity, calculate the active cooling time required to reduce the battery's highest module temperature from its current temperature to a preset temperature threshold. In this embodiment, the thermal management system's cooling capacity represents the battery's hourly temperature reduction, with the preset temperature threshold being 40°C.

[0152] Step 203: Determine the feasibility of natural cooling.

[0153] In a specific implementation, the natural cooling available time is calculated. The natural cooling available time is the difference between the user available time and the time required for full charging and the active cooling time. For example, the natural cooling available time is expressed using the formula:

[0154] T cool_natural =T available -T charge -T cool_active

[0155] Among them, T cool_natural is the available time for natural cooling, T available is the user's available time, T charge T is the time required to fill cool_active Active cooling time.

[0156] If the natural cooling available time is less than or equal to 0, that is, T cool_natural ≤0, the thermal management system is directly activated at this time, and charging begins after the battery temperature drops below 40°C to ensure that high-temperature charging is prohibited.

[0157] If the natural cooling available time is greater than 0, that is, T cool_natural >0, then according to the current battery temperature T current and ambient temperature T env The optimal cooling strategy is selected based on the relationship between them.

[0158] Specifically, if T current >T env , start the natural cooling countdown T cool_natural , using environmental heat dissipation to reduce battery temperature.

[0159] If T current ≤T env , if the current temperature T current <40℃, directly enter the charging process.

[0160] If T current≥40℃: Due to the high ambient temperature, natural cooling is not feasible and the thermal management system is forced to start.

[0161] Step 204: Dynamic adjustment and charging triggering.

[0162] In specific implementation, after the natural cooling countdown ends, that is, T cool_natural ≤0, if the battery temperature T current >40℃, start thermal management until the temperature reaches the target, that is, actively cool it until the temperature is below 40℃.

[0163] If T current ≤40℃, start charging immediately.

[0164] In this embodiment, the charging process is continuously monitored. If the temperature rises back to a critical value (eg, 45° C.), charging is suspended and the cooling process is restarted.

[0165] Step 205: Low battery protection mechanism.

[0166] In a specific implementation, if the battery SOC is lower than a preset threshold (eg, 15%), it is prioritized to be quickly charged to 20% SOC, and then the above logic is executed to avoid deep discharge damage.

[0167] Step 206: Dynamic strategy optimization.

[0168] In specific implementation, through the BMS's sleep and wake-up function and time variables, each time the vehicle wakes up, it re-evaluates changes in user usage time, ambient temperature fluctuations, and battery status changes.

[0169] This embodiment uses an intelligent temperature control strategy to address the three core issues of accelerated battery degradation caused by high-temperature charging, high thermal management energy consumption, and rigid static strategies. It adopts dynamic calculation of natural cooling time, differentiated cooling according to ambient temperature, low-battery staged protection, and real-time temperature monitoring to achieve the efficient energy-saving goals of extending battery life and reducing cooling energy consumption.

[0170] In this embodiment, intelligent dual-mode cooling automatically switches between natural and active cooling, fully utilizing ambient temperature differences to reduce vehicle energy consumption. Simultaneously, a temperature constraint is enforced, forcing the battery to be ≤40°C before charging, directly suppressing accelerated degradation at high temperatures. Finally, a tiered protection mechanism is implemented. When the vehicle battery charge is less than 15%, fast charging to 20% is prioritized to prevent deep discharge damage.

[0171] It should be noted that the method of the embodiments of the present disclosure can be performed by a single device, such as a computer or server. The method of the embodiments of the present disclosure can also be applied in a distributed scenario, where multiple devices cooperate to perform the method.
