Description

Technical Field

[0001] This disclosure relates to the field of battery technology, and in particular to a method, apparatus, device, and medium for determining charging intent. Background Technology

[0002] Currently, new energy vehicles are a key focus of the automotive industry. Among them, the battery is a crucial component that drives the vehicle. Because batteries are easily affected by environmental factors during charging, charging is slow and takes a long time. Preheating the battery can reduce charging time, but related technologies can only use the user's navigation destination as a standard to predict charging intentions. They cannot flexibly and accurately predict charging intentions, and therefore cannot control the vehicle's status in advance based on its subsequent use, such as shortening charging time by preheating the battery. Summary of the Invention

[0003] To solve the above-mentioned technical problems, or at least partially solve them, this disclosure provides a method, apparatus, device, and medium for determining charging intention, which can automatically identify the user's charging intention and facilitate subsequent control of the vehicle to preheat the battery in a timely manner.

[0004] In a first aspect, embodiments of this disclosure provide a method for determining charging intent, including:

[0005] During vehicle operation, determine whether the vehicle's battery temperature is less than or equal to the preset temperature;

[0006] If the vehicle's battery temperature is less than or equal to the preset temperature, the user's charging intention is determined based on the vehicle's current driving data and historical charging data.

[0007] Optionally, based on the vehicle's current driving data and historical charging data, the user's charging intention can be determined, including:

[0008] Based on the navigation information in the current driving data, determine whether the vehicle's navigation destination is a charging station;

[0009] If the vehicle's navigation destination is a charging station, then the user's charging intention is determined to be "charging permitted".

[0010] If the vehicle's navigation destination is not a charging station, the confidence level of the user's charging intention is determined based on the current driving data and historical charging data, and the user's charging intention is determined based on the confidence level of the user's charging intention.

[0011] Optionally, the user's charging intention is determined based on the confidence level of the user's charging intention, including:

[0012] If the confidence level of the user's charging intention is within the first confidence level range, then the user's charging intention is determined to be that charging is permitted.

[0013] If the user's charging intention confidence level is within the second confidence level range, then prompt the user with charging preheating interaction information, and determine the user's charging intention based on the user's feedback interaction results;

[0014] The lower limit of the first confidence range is greater than the upper limit of the second confidence range.

[0015] Optionally, the second confidence range includes the first subrange and the second subrange.

[0016] Optionally, if the user's charging intention confidence level is within the second confidence level range, then the user is prompted with charging preheating interaction information, and based on the user's feedback interaction results, the user's charging intention is determined, including:

[0017] If the user's confidence level in charging intention is within the first sub-range, a weak reminder will be used to prompt the user with charging preheating interaction information. The weak reminder will be sent to the user through the vehicle's multimedia system.

[0018] If the user's confidence level in charging intention falls within the second sub-range, a strong reminder will be sent to the user to prompt them with charging preheating interaction information. The strong reminder will be sent to the user via multimedia to prompt them with charging preheating interaction information, and at the same time, a text message will be sent to the user's mobile terminal.

[0019] Optionally, if the vehicle's navigation destination is a charging station, then the user's charging intention is determined to be permitted, including:

[0020] If the vehicle's navigation destination is a charging station, then determine whether the vehicle's remaining battery power is less than a preset threshold.

[0021] If the remaining battery power is less than a preset threshold, a weak reminder will be sent to the user to prompt the charging preheating interaction information, and the user's charging intention will be determined to allow charging.

[0022] If the remaining battery power is greater than or equal to a preset threshold, the confidence level of the user's charging intention is determined based on the current driving data and historical charging data, and the user's charging intention is determined based on the confidence level of the user's charging intention.

[0023] Optionally, after determining the user's charging intention, the method may also include:

[0024] If the user's charging intention is to allow charging, the battery preheating start time is determined based on the preheating charge required for the vehicle's battery to preheat.

[0025] Send a reminder message to the vehicle, including the start time of the warm-up.

[0026] Optionally, after determining the user's charging intention, the method may also include:

[0027] If the user's charging intention is to allow charging, then determine whether the vehicle's remaining battery power is sufficient for preheating; if so, preheat the vehicle's battery.

[0028] Secondly, embodiments of this disclosure provide a charging intention determination device, comprising:

[0029] The judgment unit is used to determine whether the vehicle's battery temperature is less than or equal to a preset temperature during vehicle operation.

[0030] The determination unit is used to determine the user's charging intention based on the vehicle's current driving data and historical charging data if the vehicle's battery temperature is less than or equal to a preset temperature.

[0036] Fourthly, embodiments of this disclosure provide a computer-readable storage medium having a computer program stored thereon, characterized in that the computer program, when executed by a processor, implements the steps of the charging intention determination method as described above.

[0037] This disclosure provides a method for determining charging intent. During vehicle operation, relevant vehicle data is acquired in real time to determine if the vehicle's battery temperature is less than or equal to a preset temperature. If so, the user's charging intent is determined based on current driving data and historical charging data. This method can automatically identify the user's charging intent based on relevant vehicle data, is easy to implement, highly flexible, and can further reduce charging time and improve user experience.

[0047] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0048] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0049] To reduce battery charging time, some vehicles are equipped with an on-the-go battery preheating function. This function typically refers to the vehicle preheating the battery while the user is using in-car navigation to reach a supercharging station, ensuring that the battery temperature is within the optimal range for charging upon arrival at the charging station, thereby reducing the average charging time by 25%. However, this technology can only use the user's navigation destination as a standard to predict charging intentions, and cannot flexibly and accurately predict charging intentions. Therefore, it cannot control the vehicle's status in advance based on the vehicle's subsequent usage. For example, there are many limitations to using battery preheating to shorten charging time, and it is impossible to allocate resources reasonably to ensure that battery preheating can be carried out, resulting in time-consuming charging and a poor user experience.

[0050] To address the aforementioned technical issues, this disclosure provides a method for determining charging intent. This method automatically identifies the user's charging intent based on relevant vehicle data. Once the charging intent is determined to be valid, a charging preheating reminder can be sent to the user to prevent missing the battery preheating start time. This method offers high flexibility, further reduces charging time, and improves the user experience.

[0051] Specifically, the method can be executed by the vehicle or the server. Specifically, the vehicle or server can determine the charging intention by obtaining the vehicle's current driving-related data.

[0052] For example, in one application scenario, such as Figure 1 As shown, server 12 obtains the vehicle's current driving-related data and determines the charging intention based on this data. Vehicle 11 obtains the charging intention from server 12 and then performs subsequent operations based on this intention, such as sending a battery preheating reminder message to the user. This current driving-related data can be generated by vehicle 11 in real time.

[0053] In another application scenario, vehicle 11 acquires current driving-related data and determines its charging intention based on this data. Then, if charging is permitted, it sends a battery preheating reminder to the user. The following describes the charging intention determination method in detail using vehicle 11 as an example through one or more embodiments.

[0054] It is understood that the charging intention determination method provided in the embodiments of this disclosure is not limited to the above-mentioned possible scenarios.

[0055] Figure 2 This is a flowchart illustrating a method for determining charging intention provided in an embodiment of the present disclosure, specifically including the following steps S210 to S220:

[0056] S210. During vehicle operation, determine whether the vehicle's battery temperature is less than or equal to a preset temperature.

[0057] Understandably, during vehicle operation, real-time vehicle data is acquired. This data may include battery information and driving-related data. Based on the battery information, the system determines whether the current battery temperature is lower than or equal to a preset temperature. This preset temperature can be the temperature at which the vehicle is configured to activate battery preheating; it can be understood as the temperature condition for activating battery preheating. If the temperature condition is met, the system continues to determine the user's charging intention. If the battery temperature is higher than or equal to the preheating temperature, battery preheating is not required, and the user's charging intention may not be determined. The preset temperature is the temperature corresponding to the optimal charging state, and the preset temperature could be 22 degrees Celsius. The real-time acquired driving-related data includes navigation information, driving route, and driving time.

[0058] S220. If the vehicle's battery temperature is less than or equal to the preset temperature, the user's charging intention is determined based on the vehicle's current driving data and historical charging data.

[0059] Optional, historical charging-related data includes travel data, vehicle data, and charging data.

[0060] Understandably, based on the above S210, the real-time vehicle driving-related data is the vehicle's current driving-related data; data analysis is performed on the vehicle's current driving-related data and the corresponding historical charging-related data to determine the user's charging intention; among which, historical charging-related data includes travel data, vehicle data, and charging data. Travel data refers to the user's travel route, time, start point, and destination, etc.; vehicle data refers to the data related to various components in the vehicle; and charging data refers to the user's charging time, charging habits, and charging pile data, etc.

[0061] Optionally, after determining the user's charging intention, if the user's charging intention is to allow charging, the preheating start time of the battery is determined based on the preheating charge required for the vehicle's battery to preheat; and a reminder message including the preheating start time is sent to the vehicle.

[0062] Understandably, based on the above S220, if the user's charging intention is to allow charging, the preheating power required for the vehicle's battery to preheat is obtained. Preheating power refers to the amount of electricity required to raise the battery's temperature from its current temperature to a preset temperature. Then, the preheating power required for battery preheating is calculated. This preheating power can be obtained by consulting a table comparing temperature difference and preheating power. Temperature difference refers to the temperature value between the current battery temperature and the preheating temperature. The preheating time is obtained by dividing the preheating power by the preheating temperature. Based on the preheating time, the optimal preheating time or preheating start time is determined. The optimal preheating time ensures that the battery temperature is at the preset temperature during charging, meaning that the battery is charged in its optimal charging state. After determining the optimal preheating time (preheating start time), a reminder message including the optimal preheating time is sent to the vehicle. The user can then choose to automatically preheat the battery at the optimal preheating time or manually activate the preheating process. The specific method of activating battery preheating is not limited.

[0063] This disclosure provides a method for determining charging intent. While the vehicle is in motion, relevant vehicle data is acquired in real time to determine if the battery temperature is less than or equal to a preset temperature. If so, the user's charging intent is determined based on current driving data and historical charging data. If the user's charging intent indicates that charging is permitted, a reminder can be sent to the user. This method can automatically identify the user's charging intent based on relevant vehicle data and send a charging preheating reminder to the user accordingly. This timely and accurate delivery of charging preheating reminders prevents users from missing the optimal battery preheating time, further reduces charging time, and improves the user experience.

[0064] Based on the above embodiments, Figure 3 This is a flowchart illustrating a method for determining charging intention provided in an embodiment of this disclosure. Optionally, the user's charging intention is determined based on the vehicle's current driving-related data and historical charging-related data, specifically including, for example... Figure 3 The following steps S310 to S330 are shown:

[0065] S310. Based on the navigation information in the current driving-related data, determine whether the vehicle's navigation destination is a charging station.

[0066] Understandably, if the vehicle's battery temperature is less than or equal to the preset temperature, the navigation destination will be determined based on the navigation information in the current driving data.

[0067] S320. If the vehicle's navigation destination is a charging station, then the user's charging intention is determined to be "charging permitted".

[0068] Understandably, based on the above S310, if it is determined that the vehicle's navigation destination is a charging station, then the charging intention can be directly determined as allowing charging.

[0069] S330. If the vehicle's navigation destination is not a charging station, then determine the user's charging intention confidence level based on the current driving data and historical charging data, and determine the user's charging intention based on the user's charging intention confidence level.

[0070] Understandably, based on the above S310, if the vehicle's navigation destination is not a charging station, further data analysis is performed on current driving-related data and historical charging-related data to obtain the user's charging intention confidence level. The user's charging intention confidence level can be understood as the probability that the user will charge during the current driving process. For example, if the vehicle is currently driving on its way home from get off work, the probability of the user charging after reaching the destination is relatively high. Alternatively, if the user's charging time is periodic, the probability of charging is also relatively high when a cycle is reached. Subsequently, the relationship between the user's charging intention confidence level and a preset confidence range is determined. Different methods are used to determine the user's charging intention within different preset confidence ranges. Specifically, the preset confidence range includes the first confidence range and the second confidence range described below. The preset confidence level can be determined based on the actual situation of the vehicle.

[0071] Optionally, the user's charging intention is determined based on the confidence level of the user's charging intention. Specifically, if the confidence level of the user's charging intention is within the first confidence level range, the user's charging intention is determined to be "allow charging"; if the confidence level of the user's charging intention is within the second confidence level range, the user is prompted with charging preheating interaction information, and the user's charging intention is determined based on the interaction results of the user's feedback.

[0072] Understandably, if the confidence level of the determined user's charging intention falls within the first confidence level range, the user's charging intention can be directly determined as allowing charging. The first confidence level range can be between 80% and 100%, excluding 80%, and can be determined based on the actual situation of the vehicle. If the confidence level of the determined user's charging intention falls within the second confidence level range, the user is prompted with charging preheating interaction information. Based on the user's feedback, the user's charging intention is determined. This notification can be made via a pop-up window on the in-vehicle screen, allowing the user to choose whether to preheat the battery, resulting in user feedback. This feedback can be either allowing or refusing battery preheating. Prompting the user with charging preheating interaction information ensures that when the confidence level of the user's charging intention is low based on driving data analysis—that is, when the current driving data is abnormal compared to historical driving data—an initial reminder can be given to the user. Simultaneously, current driving data can be obtained to facilitate accurate identification of the user's charging intention later.

[0073] Optionally, the lower limit of the first confidence range is higher than the upper limit of the second confidence range.

[0074] Understandably, the lower limit of the first confidence range is higher than the upper limit of the second confidence range, which can be 0 to 80%.

[0075] Optionally, the second confidence range includes a first sub-range and a second sub-range; wherein the lower limit of the first sub-range is higher than the upper limit of the second sub-range.

[0076] Understandably, the second confidence range includes the first sub-range and the second sub-range, which means that the second confidence range is refined. The lower limit of the first sub-range is higher than the upper limit of the second sub-range. The first sub-range can be 40% to 80%, excluding 40% and including 80%, and the second sub-range can be 0 to 40%, including 40%.

[0077] Optionally, if the user's confidence level in charging intention is within the first sub-range, a weak reminder method is used to prompt the user with charging preheating interaction information. The weak reminder method is to send the charging preheating interaction information to the user through the vehicle's multimedia system.

[0078] Understandably, if the confidence level of the determined user's charging intention falls within the first sub-range, a weak reminder method is used to prompt the user with charging preheating interaction information. This weak reminder method involves sending the charging preheating interaction information to the user via the vehicle's multimedia system, or sending a pop-up window containing the charging preheating interaction information to the user via the vehicle's screen. The user then chooses whether to preheat the battery based on the pop-up window, and the user's charging intention is determined based on the user's feedback. If the user chooses to allow preheating, the determined user's charging intention is to allow charging; if the user chooses to refuse preheating, the determined user's charging intention is to refuse charging.

[0079] Optionally, if the user's confidence level in charging intention falls within the second sub-range, a strong reminder method is used to prompt the user with charging preheating interaction information. The strong reminder method involves sending charging preheating interaction information to the user via multimedia and simultaneously sending an SMS reminder to the user's mobile terminal.

[0080] Understandably, if the confidence level of the determined user's charging intention falls within the second sub-range, a strong reminder method is used to prompt the user with charging preheating interaction information. This strong reminder method involves sending the charging preheating interaction information to the user via the vehicle's multimedia system, simultaneously sending an SMS notification to the user's mobile device, or sending a pop-up window containing the charging preheating interaction information to the user via the vehicle's screen. The user can then choose whether to preheat the battery based on the pop-up window, and an SMS notification is sent to the user's mobile device to prevent the user from missing the battery preheating notification. Based on the user's feedback, the user's charging intention is determined. If the user chooses to allow preheating, the determined user's charging intention is to allow charging; if the user chooses to refuse preheating, the determined user's charging intention is to refuse charging.

[0081] This disclosure provides a method for determining charging intent. It determines a user's charging intent by selecting different methods based on whether the navigation destination is a charging station. If the navigation destination is a charging station, the user's charging intent can be directly determined as "charging permitted." If the navigation destination is not a charging station, the confidence level of the user's charging intent is determined based on current driving-related data and historical charging-related data, and the user's charging intent is then determined based on this confidence level. This method can automatically identify the user's charging intent. Even when the navigation destination is a charging station, it can also determine the user's charging intent based on the confidence level determined by relevant vehicle driving information. This approach is easy to implement, highly flexible, and provides high accuracy in identifying the user's charging intent.

[0082] Based on the above embodiments, Figure 4 This is a flowchart illustrating a method for determining charging intent according to an embodiment of the present disclosure. Optionally, if the vehicle's navigation destination is a charging station, the user's charging intent is determined to be "allow charging," specifically including the following steps S410 to S430:

[0083] S410. If the vehicle's navigation destination is a charging station, determine whether the vehicle's remaining battery power is less than a preset threshold.

[0084] Understandably, if the vehicle's navigation destination is a charging station, meaning the user has decided to charge, then the remaining battery power is obtained, and it is determined whether the remaining battery power is less than a preset threshold. In other words, it's determined whether the remaining battery power supports battery preheating. The preset threshold can be the starting charging level for most vehicles. For example, if 70% of vehicles will charge when the remaining battery power is 30%, then the preset threshold can be set to 30%.

[0085] S420. If the remaining battery power is less than a preset threshold, a weak reminder will be used to prompt the user with charging preheating interaction information, and the user's charging intention will be determined to allow charging.

[0086] Understandably, based on the above S410, if the remaining battery power is less than a preset threshold, a weak reminder can be used to prompt the user with charging preheating interaction information, and the user's charging intention can be determined based on the user's feedback interaction results. For details on the weak reminder method, please refer to the above description, which will not be repeated here.

[0087] S430 If the remaining battery power is greater than or equal to a preset threshold, then determine the user's charging intention confidence level based on the current driving-related data and historical charging-related data, and determine the user's charging intention based on the user's charging intention confidence level.

[0088] Understandably, based on the above S410, if the remaining battery power is greater than or equal to a preset threshold, the confidence level of the user's charging intention is determined based on the vehicle's current driving data and historical charging data. That is, when the remaining battery power of the vehicle is greater than the starting charging power of most vehicles, the user's charging intention is further identified based on the acquired vehicle's current driving data. This will not be elaborated on here.

[0089] This disclosure provides a method for determining charging intent. When the navigation destination of a vehicle is a charging station, the remaining battery power of the vehicle is obtained. If the remaining battery power is less than a preset threshold, the user is prompted with charging preheating interaction information. Based on the user's feedback interaction results, the user's charging intent is determined. After determining that the navigation destination is a charging station, different reminder methods can be used to prompt the user whether to start battery preheating according to the remaining battery power. This method can accurately identify the user's charging intent and promptly remind the user in different situations, and can be applied to various scenarios.

[0090] Based on the above embodiments, Figure 5 This is a flowchart illustrating a method for determining charging intention provided in an embodiment of the present disclosure, specifically including the following steps S510 to S590:

[0091] S510: Acquire vehicle data during vehicle operation.

[0092] Understandably, vehicle data is acquired in real time while the vehicle is in motion. This vehicle data includes battery information, navigation information, and driving-related information.

[0093] S520: Determine if the battery temperature is less than or equal to the preset temperature.

[0094] Understandably, based on the above S510, the battery temperature is determined according to the battery information in the vehicle data, and it is determined whether the current battery temperature of the vehicle is less than or equal to the preset temperature. The preset temperature refers to the temperature condition for starting battery preheating in the vehicle configuration. If yes, then S530 is executed; if no, then the process ends.

[0095] S530: Determine whether the vehicle's navigation destination is a charging station.

[0096] Understandably, based on the above S520, the navigation destination of the vehicle is determined according to the navigation information in the vehicle data. If the battery temperature is less than or equal to the preset temperature, it is further determined whether the navigation destination is a charging station. If yes, S540 is executed; otherwise, S570 is executed.

[0097] S540: Determine whether the remaining battery power is less than a preset threshold.

[0098] Understandably, based on the above S530, the remaining battery power is determined according to the battery information in the vehicle data. If the vehicle's navigation destination is a charging station, it is further determined whether the remaining battery power is less than a preset threshold. The preset threshold can be the starting charging power of most vehicles. If yes, then S550 is executed; if no, then S570 is executed.

[0099] The S550 uses a subtle reminder method to display charging preheating information.

[0100] Understandably, based on the above S540, if the remaining battery power of the vehicle is less than a preset threshold, a weak reminder will be used to prompt charging preheating information, such as using a pop-up window to prompt charging preheating information.

[0101] S560: Determine the user's charging intention.

[0102] Understandably, based on the above S550, the user's charging intention can be determined based on the user's feedback interaction results, or the user's charging intention can be determined directly through the recognition results. The user's charging intention can be to allow preheating or refuse preheating.

[0103] S570, Determine the confidence level of the user's charging intention.

[0104] Understandably, based on the above S530 or S540, if the vehicle's navigation destination is not a charging station, or if the vehicle's remaining battery power is greater than or equal to a preset threshold, then the confidence level of the user's charging intention is determined based on the driving data and historical driving data in the vehicle data.

[0105] S580: Determine whether the confidence level of the user's charging intention is within the first confidence level range.

[0106] Understandably, based on the above S570, it is determined whether the obtained confidence level of the user's charging intention is within the first confidence level range, where the first confidence level range can be 80% to 100%, excluding 80%; if yes, then S560 is executed; if no, then S590 is executed.

[0107] S590, Determine whether the user's confidence level in charging intention is within the first subrange.

[0108] Understandably, based on the above S580, if the obtained confidence level of the user's charging intention is not within the first confidence level range, then it is necessary to continue to determine whether the confidence level of the user's charging intention is within the first sub-range, where the first sub-range can be 40% to 80%, excluding 40%; if yes, then S591 is executed; if no, then S592 is executed.

[0109] S591. Use a weak reminder method to prompt charging preheating interactive information.

[0110] Understandably, see S550 above for details, and will not be repeated here.

[0111] S592. Use a strong reminder method to display charging preheating interactive information.

[0112] Understandably, based on the above S590, if the obtained confidence level of the user's charging intention is not within the first sub-range, then the confidence level of the user's charging intention may be in the range of 0 to 40%. In this case, a strong reminder is used to prompt the charging preheating interaction information. The strong reminder can be a pop-up window to prompt the charging preheating information, and at the same time, a text message prompt is sent to the user's mobile terminal.

[0113] Based on the above embodiments, after determining the user's charging intention, if the user's charging intention is to allow charging, then it is determined whether the remaining battery power of the vehicle is sufficient for charging preheating; if so, then the vehicle's battery is controlled to preheat according to the current driving-related data.

[0114] Optionally, if the remaining battery power of the vehicle is sufficient for preheating, the vehicle's battery can be preheated based on current driving data. Specifically, this includes: determining the target charging station based on the current driving data; calculating the driving power required for the vehicle to reach the target charging station; and controlling the vehicle's battery to preheat based on the driving power, the remaining battery power, and the vehicle's battery preheating power.

[0115] Understandably, if the vehicle's remaining battery power is sufficient for preheating, the target charging station is queried and determined based on the vehicle's driving route information. The target charging station can be the nearest charging station to the vehicle or a charging station that can be passed along the driving route. Understandably, it is only necessary to select a target charging station if the vehicle's navigation destination is not a charging station. If the vehicle's navigation destination is a charging station, it can be directly determined that the user needs to charge, and there is no need to further identify the user's charging intention. Only when the navigation destination is not a charging station and the user's intention is to allow charging, is it necessary to determine a target charging station and prompt the vehicle to charge at the target charging station.

[0116] Understandably, based on the vehicle's current location, the amount of electricity required for the vehicle to travel to the target charging station is calculated. In other words, the amount of electricity the vehicle needs to travel to the target charging station requires from the battery. The amount of electricity required for the vehicle to travel to the target charging station is equivalent to the amount of electricity required for the motor to run during the journey.

[0117] Understandably, it determines the relationship between the remaining battery charge, the driving charge, and the vehicle's battery preheating charge, and controls the vehicle's battery preheating and temperature rise based on this relationship.

[0118] Optionally, if the remaining battery charge is greater than or equal to the sum of the driving charge and the battery preheating charge, the vehicle's battery is preheated and heated to a first preset temperature. At the same time, the vehicle's motor is powered to drive the vehicle.

[0119] Understandably, if the remaining battery charge is greater than or equal to the sum of the driving charge and the battery preheating charge, this means that while driving to a charging station, the vehicle can supply power to the motor to provide the power required for driving, and at the same time, it can also provide the power required for battery preheating, that is, the remaining battery charge is sufficient; the battery can be preheated to a first preset temperature, where the battery preheating charge refers to the amount of power required to raise the battery's current temperature to the preheating temperature. The preheating temperature can be the optimal charging temperature, which can be 22 degrees Celsius. In this case, the first preset temperature can be equal to the preheating temperature.

[0120] Optionally, if the remaining battery charge is less than the sum of the driving charge and the battery preheating charge, but greater than the driving charge, the battery is preheated and heated to a second preset temperature, while the motor is powered; wherein, the first preset temperature is greater than the second preset temperature.

[0121] Understandably, if the remaining battery power is less than the sum of the driving power and the battery preheating power, but greater than the driving power, meaning the remaining battery power is sufficient for driving but insufficient to provide the power needed to raise the battery temperature to the optimal charging temperature (preheating temperature), then the battery can be preheated to a second preset temperature, which is lower than the first preset temperature (optimal charging temperature). In this case, priority is given to meeting the power requirements for motor operation (driving power), and then battery preheating is performed based on the remaining power. Even if the battery cannot be preheated to the first preset temperature, it can still be preheated first. After arriving at the charging station, the battery temperature is then raised from the second preset temperature to the first preset temperature, reducing charging time.

[0122] Optionally, if the remaining battery power is less than the driving power, the battery will not be preheated, and the motor will be powered instead.

[0123] Understandably, if the remaining battery power is less than the driving range, meaning the remaining battery power is insufficient, when the vehicle travels from its current location to the charging station, only the motor needs to be powered, and there is no need to preheat the battery.

[0124] Optionally, the vehicle battery is preheated based on the driving charge, the remaining battery charge, and the vehicle's battery preheating charge. This also includes: calculating the operating charge of one or more components of the vehicle; if the remaining battery charge is greater than or equal to the sum of the driving charge, the battery preheating charge, and the operating charge, then the battery is preheated while power is supplied to the components and the motor.

[0125] Understandably, in addition to calculating the battery preheating capacity and driving capacity, the operating capacity of one or more vehicle components can also be calculated. This component could specifically be the passenger compartment air conditioning unit. In this case, it means that while the vehicle is traveling to the charging station, the remaining battery capacity can simultaneously support the driving capacity, the operating capacity of the passenger compartment air conditioning unit, and the battery preheating capacity. In other words, while the vehicle is traveling to the target charging station, it can simultaneously meet the power supply requirements of the motor, passenger compartment air conditioning unit, and battery preheating unit.

[0126] This disclosure provides a method for determining charging intent. When the user's charging intent is recognized as allowing charging, the method calculates whether the current remaining battery power can support driving power and battery preheating power. If it can, the method determines that the preheating power is sufficient and controls the vehicle's battery to preheat. This method can reasonably allocate the remaining battery power to ensure that the battery can be preheated, thereby further reducing charging time.

[0131] Optionally, the determining unit 620 determines the user's charging intention based on the confidence level of the user's charging intention.

[0132] Optionally, the second confidence range in the determination unit 620 includes a first sub-range and a second sub-range.

[0133] Optionally, in the determining unit 620, if the user's confidence level in charging intention is within the second confidence level range, then the user is prompted with charging preheating interaction information. Specifically, if the user's confidence level in charging intention is within the first sub-range, then a weak reminder is used to prompt the user with charging preheating interaction information, which is sent to the user via the vehicle's multimedia system; if the user's confidence level in charging intention is within the second sub-range, then a strong reminder is used to prompt the user with charging preheating interaction information, which is sent to the user via multimedia system and simultaneously sent to the user's mobile terminal via SMS.

[0134] Optionally, if the navigation destination of the vehicle in unit 620 is a charging station, then the user's charging intention is determined to be "allowed to charge". Specifically, if the navigation destination of the vehicle is a charging station, then it is determined whether the remaining battery power of the vehicle is less than a preset threshold; if the remaining battery power is less than the preset threshold, then a weak reminder is used to prompt the user with charging preheating interaction information, and the user's charging intention is determined to be "allowed to charge"; if the remaining battery power is greater than or equal to the preset threshold, then the confidence level of the user's charging intention is determined based on the current driving-related data and historical charging-related data, and the user's charging intention is determined based on the confidence level of the user's charging intention.

[0135] Optionally, the device 600 also includes a reminder unit, which, after determining the user's charging intention, if the user's charging intention is to allow charging, determines the battery preheating start time based on the preheating charge required for the vehicle's battery to preheat; and sends a reminder message including the preheating start time to the vehicle.

[0136] Optionally, the device 600 also includes a preheating unit, which, after determining the user's charging intention, if the user's charging intention is to allow charging, determines whether the remaining battery power of the vehicle is sufficient for charging preheating; if so, it preheats the vehicle's battery.
