Detailed Implementation

[0014] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0016] In order to ensure that the vehicle's battery is at the optimal charging temperature when the vehicle arrives at the charging station, this application provides a vehicle battery temperature adjustment method, which includes: first, in response to a navigation request to reach the target charging station, determining the state of charge (SOC) of the target vehicle's battery at the target charging station based on the total energy consumption of the target vehicle when it arrives at the target charging station; then, based on the SOC, predicting the target charging temperature of the target vehicle's battery when the charging speed is fastest; and finally, controlling the target vehicle's battery to adjust to the target charging temperature during vehicle travel, so as to ensure that the battery reaches the optimal charging temperature when the vehicle arrives at the charging station, thereby improving the charging speed and reducing thermal management energy consumption.

[0017] This application provides a method for adjusting the temperature of a vehicle battery, which will be described below with reference to specific embodiments.

[0018] Figure 1This is a flowchart illustrating a vehicle battery temperature adjustment method provided in an embodiment of this application. This method can be applied to a vehicle battery temperature adjustment device, which can be a vehicle electronic control unit (ECU).

[0019] It is understood that the vehicle battery temperature adjustment method provided in this application embodiment can also be applied in other scenarios.

[0020] The following is about Figure 1 The method for adjusting the temperature of a vehicle battery is described below. The method provided is exemplified by its application in a vehicle battery temperature adjustment device, and can be referred to as Example 1. The method provided in Example 1 may include the following steps: S110, in response to a navigation request to reach a target charging station, determine the first state of charge of the target vehicle's battery at the target charging station based on the total energy consumption of the target vehicle as it travels to the target charging station.

[0021] In this embodiment, when a user needs to charge the vehicle's battery at a charging station, the user opens the navigation software and sends a navigation request to the vehicle's controller to drive to the target charging station. The vehicle's controller transmits the request to the vehicle's battery temperature adjustment device. The temperature adjustment device responds to the navigation request by obtaining the location where navigation is enabled as the vehicle's navigation location, obtaining the location of the target charging station for battery charging, and predicting the total energy consumption of the vehicle when the target vehicle drives to the target charging station.

[0022] Furthermore, the vehicle battery temperature adjustment device predicts the first state of charge of the target vehicle at the target charging station based on the total energy consumption of the vehicle. This allows the battery to be adjusted to the optimal charging temperature based on the battery's state of charge when the vehicle arrives at the station, ensuring the fastest charging speed and avoiding unnecessary energy consumption for thermal management.

[0023] Among them, total vehicle energy consumption refers to the predicted energy consumption of the target vehicle from its navigation location (i.e., the navigation starting point) to the target charging station.

[0024] The first state of charge refers to the state of charge of the target vehicle when it arrives at the target charging station, as predicted from the vehicle's navigation location (i.e., the navigation starting point). In other words, the first state of charge is the state of charge of the battery when the vehicle arrives at the charging station.

[0025] S120. Based on the first state of charge, determine the target charging temperature of the target vehicle's battery at the target charging station, wherein the target charging temperature is located within the starting charging temperature range of the target vehicle's battery, and the charging speed corresponding to the starting charging temperature range is greater than the charging speed corresponding to other temperatures.

[0026] Understandably, since the first state of charge refers to the battery's state of charge when the vehicle arrives at the charging station, the vehicle's battery temperature adjustment equipment, based on the first state of charge, can accurately predict the optimal charging temperature of the vehicle's battery at the charging station.

[0027] The initial charging temperature range refers to the temperature range within which the battery of the target vehicle charges at its fastest rate.

[0028] For example, in a fast charging environment, the starting charging temperature range is 25°C to 35°C; in a low-temperature environment, the starting charging temperature range is 20°C to 25°C; and in a high-temperature environment, the starting charging temperature range is 30°C to 38°C.

[0029] The target charging temperature refers to the optimal charging temperature of the vehicle's battery at a charging station. Optionally, the target charging temperature can be a portion of the initial charging temperature range or a specific temperature value.

[0030] In some embodiments, the target charging temperature is any battery starting temperature within the starting charging temperature range. In other embodiments, the target charging temperature is the battery starting temperature within the starting charging temperature range that maximizes battery life. In still other embodiments, the target charging temperature is the battery starting temperature within the starting charging temperature range that maximizes battery life while minimizing energy efficiency loss.

[0031] For example, in a fast charging environment, the starting charging temperature range is 25°C to 35°C, and the target charging temperature is 30°C to 32°C; in a low-temperature environment, the starting charging temperature range is 20°C to 25°C, and the target charging temperature is 22°C to 24°C; in a high-temperature environment, the starting charging temperature range is 30°C to 38°C, and the target charging temperature is 34°C to 36°C.

[0032] For example, in a fast charging environment, the initial charging temperature range is 25°C to 35°C, and the target charging temperature is 30°C; in a low-temperature environment, the initial charging temperature range is 20°C to 25°C, and the target charging temperature is 23°C; in a high-temperature environment, the initial charging temperature range is 30°C to 38°C, and the target charging temperature is 35°C.

[0033] S130, Adjust the battery of the target vehicle to the target charging temperature of the target charging station.

[0034] Since the target charging temperature is the optimal charging temperature for the vehicle's battery at the charging station, the vehicle's battery temperature adjustment device can send the target charging temperature to the vehicle's thermal management system. This system then controls the vehicle's thermal management system to adjust the battery temperature from the vehicle's initial temperature at the navigation location to the target charging temperature of the target charging station, ensuring that the battery is charged at the optimal temperature.

[0035] The first temperature at the vehicle's navigation location can be understood as the battery temperature of the vehicle at the starting point of navigation.

[0036] This embodiment first responds to the navigation request to reach the target charging station, determines the state of charge (SOC) of the target vehicle's battery at the target charging station based on the total energy consumption of the vehicle traveling to the target charging station, then predicts the target charging temperature of the target vehicle's battery when the charging speed is fastest based on the SOC, and finally controls the target vehicle's battery to adjust to the target charging temperature during the vehicle's journey, so as to ensure that the battery reaches the optimal charging temperature when the vehicle arrives at the charging station, thereby improving the charging speed and reducing thermal management energy consumption.

[0037] Furthermore, after controlling the target vehicle's battery to adjust to the target charging temperature of the target charging station, the vehicle battery temperature adjustment device can send the target charging temperature to the target vehicle's display device for display; and / or send the target charging temperature to the target vehicle's voice playback device for playback.

[0038] Optionally, the display device can be an in-vehicle display screen of the target vehicle or an external display device that is communicatively connected to the target vehicle.

[0039] Optionally, the voice playback device can be the vehicle's in-vehicle audio system or an external voice playback device that is connected to the target vehicle.

[0040] In this way, the system will provide feedback to the user after the target vehicle's battery is adjusted to the target charging temperature of the target charging station, so that the user can start the charging operation when the battery reaches the optimal charging temperature, which will help improve the user's charging experience.

[0041] This application also provides another method for adjusting the temperature of a vehicle battery, which specifically explains the total energy consumption of a target vehicle when it travels to a target charging station.

[0042] Figure 2 A flowchart of another vehicle battery temperature adjustment method provided in this application is shown below. Figure 2 As shown, the method includes the following steps: S210, in response to a navigation request to drive to a target charging station, obtain at least one local energy consumption value of the target vehicle driving to the target charging station, wherein the at least one local energy consumption value includes driving energy consumption, low-voltage load energy consumption, air conditioning energy consumption, thermal management energy consumption and battery self-generated heat.

[0043] In this embodiment, considering the energy consumption of predicting future journeys, the vehicle battery temperature adjustment device needs to take into account the driving energy consumption, low-voltage load energy consumption, air conditioning energy consumption, thermal management energy consumption, and battery self-generated heat of the target vehicle traveling to the target charging station as local energy consumption values.

[0044] In some embodiments, firstly, driving energy consumption, low-voltage load energy consumption, and air conditioning energy consumption are obtained; then, the thermal management dissipation coefficient of the target vehicle at the target charging station, battery specific heat capacity, battery pack mass, first open-circuit voltage, battery internal resistance, and remaining time for the target vehicle to travel from the vehicle navigation location to the target charging station are obtained; based on the driving energy consumption, low-voltage load energy consumption, air conditioning energy consumption, thermal management dissipation coefficient, battery specific heat capacity, battery pack mass, first open-circuit voltage, battery internal resistance, and remaining time, the thermal management energy consumption and battery self-generated heat are determined.

[0045] Among these, driving energy consumption, low-voltage load energy consumption, and air conditioning energy consumption can be obtained directly. Thermal management energy consumption and battery self-generated heat need to be calculated.

[0046] Alternatively, thermal management energy consumption and battery self-generated heat can be determined by the following methods:

[0047]

[0048] in, It is thermal management energy consumption; The battery generates its own heat; In It is the thermal management dissipation coefficient, which is related to vehicle speed and ambient temperature; It's about the quality of the battery pack; It is the target charging temperature; This is the battery's first temperature at the vehicle's navigation location; It is the battery's internal resistance; It is the predicted battery current when the vehicle reaches the target charging station; This is the remaining time from the vehicle's navigation location to the target charging station.

[0049] Alternatively, the battery current can be determined by the following method:

[0050] in, It is the first open-circuit voltage; It is the vehicle's total energy consumption.

[0051] Alternatively, the total energy consumption of a vehicle can be determined by the following method:

[0052]

[0053] in, It refers to driving energy consumption; It is low-voltage load energy consumption; It refers to air conditioning energy consumption.

[0054] By combining the above formulas, we can calculate the thermal management energy consumption and the battery's self-generated heat.

[0055] S220. Calculate the sum of at least one local energy consumption value to obtain the total energy consumption of the vehicle.

[0056] In this embodiment, the vehicle battery temperature adjustment device determines the driving energy consumption, low-voltage load energy consumption, air conditioning energy consumption, thermal management energy consumption, and battery self-generated heat. It then adds these local energy consumption values ​​together to obtain the total vehicle energy consumption, which is recorded as follows: .

[0057] In this way, the total energy consumption of the vehicle when it arrives at the charging station is calculated based on the energy consumption of multiple local areas when the vehicle arrives at the charging station, so as to accurately predict the state of charge of the vehicle when it arrives at the charging station based on the total energy consumption of the vehicle.

[0058] S230. Based on the total energy consumption of the target vehicle as it travels to the target charging station, determine the first state of charge of the target vehicle's battery at the target charging station.

[0059] S240. Based on the first state of charge, determine the target charging temperature of the target vehicle's battery at the target charging station, wherein the target charging temperature is located within the starting charging temperature range of the target vehicle's battery, and the charging speed corresponding to the starting charging temperature range is greater than the charging speed corresponding to other temperatures.

[0060] S250: Adjust the battery of the target vehicle to the target charging temperature of the target charging station.

[0061] S230~S250 are similar to S110~S130, and will not be described in detail here.

[0062] This application also provides another method for adjusting the temperature of a vehicle battery, and this embodiment provides a detailed explanation of S110. Figure 3 A flowchart of yet another method for adjusting the temperature of a vehicle battery provided in this application is shown below. Figure 3 As shown, the method includes the following steps: S310, in response to a navigation request to drive to a target charging station, obtains the second state of charge and the second open-circuit voltage of the target vehicle's battery at the vehicle's navigation location.

[0063] In this embodiment, the vehicle battery temperature adjustment device can calculate the state of charge (SOC) of the vehicle when it arrives at the charging station based on the vehicle's total energy consumption and the Open Circuit Voltage Model (OCV) of the battery, using numerical integration. Therefore, the vehicle battery temperature adjustment device needs to obtain the second SOC and second open circuit voltage of the target vehicle at its navigation location as input data for the OCV model.

[0064] The OCV model includes the mapping relationship between the battery open-circuit voltage and the state of charge.

[0065] S320. Based on the second state of charge, the second open-circuit voltage, and the vehicle's total energy consumption, determine the first state of charge.

[0066] In this embodiment, the vehicle battery temperature adjustment device inputs the second state of charge, the second open-circuit voltage, the first open-circuit voltage, and the total energy consumption of the vehicle into the OCV model. Since the OCV model has learned the mapping relationship between the battery open-circuit voltage and the state of charge, and uses the total energy consumption of the vehicle as the area enclosed by the battery open-circuit voltage and the state of charge, the first state of charge is obtained.

[0067] In this way, after accurately predicting the state of charge of the vehicle when it arrives at the charging station, the battery OCV model is used to continue predicting the state of charge when it arrives at the charging station through numerical integration.

[0068] S330. Based on the first state of charge, determine the target charging temperature of the target vehicle's battery at the target charging station, wherein the target charging temperature is located within the starting charging temperature range of the target vehicle's battery, and the charging speed corresponding to the starting charging temperature range is greater than the charging speed corresponding to other temperatures.

[0069] S340, Adjust the battery of the target vehicle to the target charging temperature of the target charging station.

[0070] S330~S340 are similar to S120~S130, and will not be described in detail here.

[0071] This application also provides another method for adjusting the temperature of a vehicle battery, and this embodiment provides a detailed explanation of S120. Figure 4 A flowchart of another method for adjusting the temperature of a vehicle battery provided in this application is shown below. Figure 4 As shown, the method includes the following steps: S410, in response to a navigation request to reach a target charging station, determines the first state of charge of the target vehicle's battery at the target charging station based on the total energy consumption of the target vehicle during its journey to the target charging station.

[0072] S410 is similar to S110, so it will not be described in detail here.

[0073] S420. Based on the first state of charge, determine the starting charging temperature range of the target vehicle's battery at the target charging station.

[0074] Since the starting charging temperature range is the temperature range within which the battery of the target vehicle charges at its maximum speed, the starting charging temperature range can be understood as the minimum / maximum battery temperature threshold that allows the charging system to start charging.

[0075] In some embodiments, the vehicle battery temperature adjustment device uses a charging time prediction model to process the first state of charge with a calibrated minimum charging time as a constraint, and determines the starting charging temperature range, wherein the calibrated minimum charging time refers to the charging time from the battery's initial charge at the target charging station to its rated charge.

[0076] S430: Determine the target charging temperature based on the starting charging temperature range.

[0077] In some embodiments, the target charging temperature is any battery charging temperature within the starting charging temperature range.

[0078] In other embodiments, the target charging temperature is the battery starting temperature with the longest battery life within the starting charging temperature range. Specifically, the vehicle battery temperature adjustment device uses a battery temperature prediction model, with the longest battery life as a constraint, to process the starting charging temperature range to obtain the target charging temperature.

[0079] In other embodiments, the target charging temperature is the battery starting temperature within the starting charging temperature range that maximizes battery life and minimizes energy efficiency loss. Specifically, the vehicle battery temperature adjustment device uses a battery temperature prediction model to process the starting charging temperature range with the constraints of maximizing battery life and minimizing energy efficiency loss to obtain the target charging temperature.

[0080] Among them, the battery's calibrated maximum power consumption and calibrated maximum lifespan can be obtained from battery usage data.

[0081] In this way, the charging time prediction model is first used to process the vehicle's state of charge at the charging station, and the shortest charging time is used as the constraint to optimize and determine the starting charging temperature range. Then, the target charging temperature of the battery is determined from the starting charging temperature range, thereby achieving accurate determination of the target charging temperature by combining the vehicle's state of charge at the charging station.

[0082] S440: Adjust the battery of the target vehicle to the target charging temperature of the target charging station.

[0083] S440 is similar to S130, so it will not be described in detail here.

[0084] This application also provides another method for adjusting the temperature of a vehicle battery, and this embodiment provides a detailed explanation of S130. Figure 5 A flowchart of another method for adjusting the temperature of a vehicle battery provided in this application is shown below. Figure 5 As shown, the method includes the following steps: S510, in response to a navigation request to reach a target charging station, determines the first state of charge of the target vehicle's battery at the target charging station based on the total energy consumption of the target vehicle during its journey to the target charging station.

[0085] S510 is similar to S110, so it will not be described in detail here.

[0086] S520. Based on the first state of charge, determine the target charging temperature of the target vehicle's battery at the target charging station, wherein the target charging temperature is located within the starting charging temperature range of the target vehicle's battery, and the charging speed corresponding to the starting charging temperature range is greater than the charging speed corresponding to other temperatures.

[0087] S520 is similar to S120, so it will not be described in detail here.

[0088] S530, obtains the rate of change of battery temperature.

[0089] Among them, the battery temperature change rate refers to the speed at which the vehicle's temperature is adjusted during transit.

[0090] In some embodiments, the vehicle battery temperature adjustment device first obtains the second state of charge of the target vehicle at the vehicle navigation location, the target vehicle speed, and the target air conditioning opening degree. Then, based on the second state of charge, the target vehicle speed, and the target air conditioning opening degree, it determines the air conditioning operating power and obtains the battery temperature change rate based on the air conditioning operating power.

[0091] The operating power of an air conditioner can be either heating power or cooling power.

[0092] Specifically, after the vehicle battery temperature adjustment equipment obtains the second state of charge, the target vehicle speed, and the target air conditioning opening degree, it can predict the air conditioning operating power based on the second state of charge, the target vehicle speed, and the target air conditioning opening degree by looking up a table. Then, it can continue to predict the battery temperature change rate based on the air conditioning operating power by looking up a table.

[0093] S540 determines the temperature adjustment duration based on the battery temperature change rate, the first temperature, the target charging temperature, and the in-transit temperature control redundancy duration.

[0094] Among them, the in-transit temperature control redundancy time refers to the redundancy period of the pre-calibrated in-transit temperature control time, which can be adjusted according to the actual test results.

[0095] In this embodiment, the vehicle battery temperature adjustment device first calculates the temperature difference between the target charging temperature and the first temperature, then calculates the ratio of the temperature difference to the battery temperature change rate, and finally adds the calculated ratio to the temperature control redundancy time to obtain the temperature adjustment time.

[0096] Alternatively, the temperature adjustment time can be determined by the following method:

[0097] in, It refers to the temperature adjustment time; It is the target charging temperature; It is the first temperature; It is the rate of change of battery temperature; This refers to the redundant time for temperature control during transit.

[0098] S550: During the temperature adjustment period, according to the rate of change of battery temperature, control the battery of the target vehicle to adjust from the first temperature at the vehicle navigation location to the target charging temperature of the target charging station.

[0099] In this embodiment, after determining the temperature adjustment duration and the battery temperature change rate, the vehicle battery temperature adjustment device can control the execution of on-the-go temperature adjustment according to the battery temperature change rate within the temperature adjustment duration, so that the battery in the vehicle reaches the optimal charging temperature at the charging station.

[0100] Understandably, the temperature adjustment time is a theoretical time for controlling temperature adjustment. In some cases, when the vehicle is close to a charging station, the remaining navigation time may be less than the temperature adjustment time. In this situation, the vehicle's battery temperature adjustment device immediately activates on-the-go temperature control.

[0101] In some embodiments, during the remaining time that the target vehicle travels from its navigation location to the target charging station, the vehicle battery temperature adjustment device controls the target vehicle's battery to adjust from a first temperature at the vehicle navigation location to a second temperature at the target charging station location, according to the battery temperature change rate. The remaining time is less than the temperature adjustment time, and the second temperature is less than the target charging temperature.

[0102] In this way, when the remaining navigation time is less than the temperature adjustment time, the on-the-go temperature control is activated immediately to adjust the battery temperature to the second temperature as soon as possible, so that when the vehicle arrives at the charging station, the battery temperature is as close as possible to the optimal charging temperature.

[0103] This application also provides another method for adjusting the temperature of a vehicle battery. Figure 6 A flowchart of another method for adjusting the temperature of a vehicle battery provided in this application is shown below. Figure 6 As shown, the method includes the following steps: S610, in response to a navigation request to reach a target charging station, determines the first state of charge of the target vehicle's battery at the target charging station based on the total energy consumption of the target vehicle as it travels to the target charging station.

[0104] S620. Based on the first state of charge, determine the target charging temperature of the target vehicle's battery at the target charging station, wherein the target charging temperature is located within the starting charging temperature range of the target vehicle's battery, and the charging speed corresponding to the starting charging temperature range is greater than the charging speed corresponding to other temperatures.

[0105] S630: Adjust the battery of the target vehicle to the target charging temperature of the target charging station.

[0106] S610~S630 are similar to S110~S130, and will not be described in detail here.

[0107] S640: Obtain time-saving information for the target vehicle.

[0108] Among them, the time-saving information is used to characterize the rate of saving of charging speed when the on-the-go temperature control strategy is enabled compared to the charging speed when the on-the-go temperature control strategy is not enabled.

[0109] In some embodiments, the vehicle battery temperature adjustment device first determines a first estimated charging time for the target vehicle based on a target charging temperature and a first state of charge, then determines a second estimated charging time for the target vehicle based on the first temperature and the first state of charge, and finally determines time-saving information based on the first and second estimated charging times.

[0110] Specifically, the vehicle battery temperature adjustment device inputs the target charging temperature and the first state of charge when the vehicle arrives at the charging station into the charging time estimation model to calculate the first estimated charging time. It also inputs the first battery temperature when the in-transit temperature control strategy is activated and the first state of charge when the vehicle arrives at the charging station into the charging time estimation model to calculate the second estimated charging time. Finally, based on the first and second estimated charging times, the charging time benefit before and after the in-transit temperature control strategy is activated is determined.

[0111] Alternatively, the time-saving information for the target vehicle can be determined using the following methods:

[0112] in, This is time-saving information for the target vehicle; This is the first estimated charging time; This is the second estimated charging time.

[0113] S650: Send time-saving information to the display device of the target vehicle for display.

[0114] In this embodiment, after the vehicle battery temperature adjustment device calculates the time-saving information, it sends the time-saving information to the display device of the target vehicle for display, so that the user can view the time-saving information and improve the user's charging experience.

[0115] The following description is provided in conjunction with the accompanying diagram, such as... Figure 7 The overall logic of the vehicle battery temperature adjustment method is explained as shown.

[0116] First, the vehicle battery temperature adjustment device acquires navigation data, vehicle driving data, and battery data. Then, based on these data, it predicts the total energy consumption of the vehicle as it travels to the charging station. Next, it predicts the battery's state of charge (SOC) upon arrival at the charging station. Further, based on the SOC, it determines the initial charging temperature range for the battery at the charging station. Then, it determines the target charging temperature based on this range. Next, it determines the air conditioning operating power and, based on that, the battery temperature change rate and temperature adjustment duration. Finally, it performs thermal management based on the battery temperature change rate and adjustment duration to control the vehicle's battery to reach the target charging temperature of the charging station.

[0117] Furthermore, the vehicle battery temperature adjustment device determines time-saving information based on the target charging temperature, the battery's state of charge when the vehicle arrives at the charging station, and the temperature of the vehicle at its navigation location, in order to optimize charging time.

[0118] Optionally, navigation data may include the remaining time for the vehicle to travel from the navigation location to the charging station.
