[0063] The following describes the present invention based on embodiments, but the present invention is not limited to these embodiments. In the following detailed description of the present invention, some specific details are described in detail. Those skilled in the art can fully understand the present invention without the description of these details. In order to avoid obscuring the essence of the present invention, well-known methods, processes, procedures, elements, and circuits are not described in detail.

[0064] In addition, those of ordinary skill in the art should understand that the drawings provided herein are for illustrative purposes only, and the drawings are not necessarily drawn to scale.

[0065] Unless the context clearly requires otherwise, the words "including", "comprising" and similar words in the specification shall be construed in an inclusive sense rather than an exclusive or exhaustive sense; that is, it is the meaning of "including but not limited to".

[0066] In the description of the present invention, it should be understood that the terms "first", "second", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. In addition, in the description of the present invention, unless otherwise specified, the meaning of "a plurality" is two or more.

[0067] During low-temperature charging of rechargeable batteries, lithium metal accumulation often occurs due to reasons such as chemical reactions inside the battery. When the accumulation reaches a certain amount, lithium metal dendrites will form and pierce the battery separator, resulting in an internal short-circuit accident. To avoid the above risks, battery manufacturers or original equipment manufacturers (OEMs) will formulate low-temperature charging strategies to limit the battery current magnitude at low temperatures. However, while limiting the battery current magnitude at low temperatures, the battery charging efficiency decreases, and the battery charging time will also be extended for a long time.

[0068] Based on this, to improve the impact of low-temperature environments on battery charging, a common measure is to equip the battery thermal management system with a heating device, which is turned on during battery charging. However, taking the vehicle battery in a new energy vehicle as an example, this method of adding a heating device to provide heating for battery charging can, to a certain extent, alleviate the problem of slow charging under low-temperature conditions, but there is still much room for improvement compared to the refueling time of fuel vehicles.

[0069] Next, the charging of the vehicle battery in an online car-hailing service platform will be used as an example for illustration. It should be understood that with the widespread use of new energy vehicles, the information interaction method in this embodiment can be applied not only to online cars providing online car-hailing services, but also to cloud battery management systems, charging reservation service platforms, fast charging service platforms, in-vehicle battery management control systems, etc., and is not limited here.

[0070] Figure 1 It is a flowchart of the information interaction method on the server side. As Figure 1 shown, the information interaction method of this embodiment is applied to the server and specifically includes the following steps.

[0071] In step S100, vehicle information and charging pile information of the target vehicle are obtained. Among them, the vehicle information includes vehicle position information and the initial battery temperature, and the charging pile information includes the target charging pile position information.

[0072] In step S200, a guiding speed for the target vehicle to reach the target charging pile is determined based on the vehicle information and the charging pile information. When the target vehicle travels to the target charging pile at the guiding speed, the battery temperature rises from the initial battery temperature to a preset temperature, and the battery charging efficiency at the preset temperature is higher than that at the initial battery temperature.

[0073] Optionally, when the target vehicle travels to the target charging pile at the guiding speed, the preset temperature can be the battery temperature corresponding to the highest charging efficiency of the target vehicle. When the battery temperature reaches the above preset temperature, the charging efficiency of the vehicle battery of the target vehicle is the highest, the charging time is the shortest, and the waiting cost consumed by the vehicle driver for waiting for battery charging is the lowest.

[0074] Furthermore, the setting of the preset temperature can be determined based on the cloud data of the corresponding vehicle model of the target vehicle collected on the online car-hailing service platform. For example, by obtaining all the cloud data of vehicle model A on the online car-hailing service platform, determining the charging time required for each vehicle to increase the battery power from 20% to 90% at different temperatures, and determining the temperature corresponding to the data with the shortest charging time as the preset temperature of the vehicle battery of the target vehicle.

[0075] Furthermore, the waiting cost of the vehicle driver mentioned in this embodiment is determined by the product value of the basic waiting cost of the vehicle driver and the charging time. The larger the product value, the higher the waiting cost of the corresponding vehicle driver. Among them, the basic waiting cost of the vehicle driver is determined according to the ratio of the income obtained by the target driver corresponding to the target vehicle for executing historical orders within a preset time period to the time consumed. The larger the ratio, the higher the basic waiting cost of the vehicle driver.

[0076] In step S300, the vehicle speed required to heat the vehicle battery is prompted to the target vehicle according to the guiding speed.

[0077] The technical solution of the embodiment of the present invention determines the guiding speed for the target vehicle to reach the target charging pile based on the vehicle information and the charging pile information by obtaining the vehicle information and the charging pile information of the target vehicle, and prompts the vehicle speed required to heat the vehicle battery to the target vehicle according to the guiding speed, so that the vehicle battery is heated by the heat generated during vehicle driving during the journey of the target vehicle to the target charging pile. Compared with only relying on the heat generated by battery discharge during vehicle driving without a guiding speed and the traditional method of relying on a battery heating device for battery warming, the battery warming speed is faster, and while saving battery power, the battery temperature of the target vehicle can be quickly increased from the initial battery temperature to the preset temperature, thereby improving the charging efficiency of the vehicle battery after the target vehicle reaches the target charging pile, reducing the charging time, and saving the time cost consumed by battery charging.

[0078] Optionally, before obtaining the target vehicle, the information interaction method of this embodiment further includes: receiving a reservation request of the target vehicle. The reservation request includes vehicle information.

[0079] Optionally, the information interaction method of this embodiment further includes: obtaining the power information of the target vehicle, where the power information is used to characterize the battery power of the target vehicle; and, in response to the battery power of the target vehicle being less than the preset power, sending the charging pile information to the target vehicle.

[0080] Optionally, the vehicle information in this embodiment further includes vehicle identification information. As Figure 2 shown, the above step S200 in this embodiment is implemented through the following steps.

[0081] In step S210, obtain historical operation data based on the vehicle identification information.

[0082] Optionally, when obtaining the historical operation data, the vehicle identification information in this embodiment may be the unique identification information corresponding to the target vehicle, or the unique identification information corresponding to the vehicle model to which the target vehicle belongs, or the unique identification information corresponding to the vehicle battery type configured by the target vehicle.

[0083] Furthermore, to improve the representativeness of the guiding vehicle speed and reduce the complexity of method implementation, the vehicle identification information in this embodiment adopts the unique identification information corresponding to the vehicle model to which the target vehicle belongs.

[0084] In step S220, determine the temperature rise relationship table of the target vehicle based on the historical operation data. The temperature rise relationship table is used to characterize the battery temperature rise per unit time corresponding to the target vehicle in different vehicle speed ranges.

[0085] In this embodiment, the vehicle speed range in the temperature rise relationship table starts with an average speed of 20 - 30 km / h and increases upward in a gradient of 10 km / h, specifically including 20 - 30 km / h, 30 - 40 km / h, ···. The battery temperature rise is the temperature rise value generated every 10 minutes. For example, when the average speed is in the range of 20 - 30 km / h, the corresponding battery temperature rise is 0.7℃ / 10min; when the average speed is in the range of 30 - 40 km / h, the corresponding battery temperature rise is 1.0℃ / 10min; when the average speed is in the range of 40 - 50 km / h, the corresponding battery temperature rise is 1.3℃ / 10min. And, the vehicle speed range interval in this embodiment may only include one side endpoint value. For example, when the vehicle speed is 30 km / h, it may belong to the vehicle speed range of 20 - 30 km / h or the vehicle speed range of 30 - 40 km / h.

[0086] It should be understood that as the vehicle driving speed increases, the corresponding battery temperature rises faster. That is, the faster the average speed of the vehicle, the higher the battery temperature rise per unit time.

[0087] In step S230, the guiding speed is determined based on the vehicle position information, the target charging pile position information, and the temperature rise relationship table.

[0088] Optionally, as Figure 3 shown, when determining the guiding speed based on the vehicle position information, the target charging pile position information, and the temperature rise relationship table in this embodiment, the following steps are included.

[0089] In step S231, the driving distance of the target vehicle is determined based on the vehicle position information and the position information of the target charging pile.

[0090] Optionally, the vehicle position information in this embodiment is used to represent the display position corresponding to the current location of the target vehicle on the map. The position information of the target charging pile is used to represent the display position corresponding to the target charging pile on the same map. The driving distance of the target vehicle can be the straight-line distance between the vehicle position information and the target charging pile position information, or the actual travel distance corresponding to the navigation route from the current position of the target vehicle to the target charging pile.

[0091] Furthermore, the driving distance of the target vehicle in this embodiment is the actual travel distance corresponding to the navigation route from the current position of the target vehicle to the target charging pile. When there are multiple navigation routes, the driving distance of the target vehicle is the average value of the actual travel distances corresponding to all navigation routes or the driving distance of the shortest navigation route.

[0092] In step S232, the heating temperature difference is determined based on the initial battery temperature and the preset temperature.

[0093] In this embodiment, the heating temperature difference is the difference between the preset temperature and the initial battery temperature.

[0094] In step S233, the vehicle speed range that simultaneously satisfies the driving distance and the heating temperature difference is selected from the temperature rise relationship table, and the vehicle speeds within the vehicle speed range are determined as the guiding speeds.

[0095] In this embodiment, when determining the guiding speed, the intermediate vehicle speed in each vehicle speed range is selected for calculation, and the vehicle speeds within the speed range where the intermediate vehicle speed satisfies the following relational expression are determined as the guiding speeds.

[0096]

[0097] Among them, T in the above formula is the heating temperature difference, with the unit of °C; s is the driving distance, with the unit of km; v is the intermediate vehicle speed, with the unit of km / h; Δt is the battery temperature rise corresponding to the speed range where the intermediate vehicle speed is located, with the unit of °C / 10min.

[0098] Optionally, the guiding vehicle speed in this embodiment can adopt the intermediate vehicle speed in each speed range. Thus, it is convenient to quickly determine the guiding vehicle speed for the target vehicle to drive to the target charging pile, improve the determination efficiency of the guiding vehicle speed, and further reduce the waiting cost of the vehicle driver.

[0099] Optionally, as Figure 4 shown, the steps for prompting the target vehicle to heat the vehicle battery according to the guiding vehicle speed in this embodiment are as follows.

[0100] In step S310, obtain the guiding vehicle speed.

[0101] In step S320, determine whether the guiding vehicle speed is greater than the restricted vehicle speed. The restricted vehicle speed is used to represent the speed limit value that appears on the road where the target vehicle is driving towards the target charging station. When the guiding vehicle speed is not greater than the restricted vehicle speed, that is, when the guiding vehicle speed is less than or equal to the restricted vehicle speed, execute step S330; when the guiding vehicle speed is greater than the restricted vehicle speed, execute step S340.

[0102] Optionally, when there are multiple speed limit values during the target vehicle driving towards the target charging station, the restricted vehicle speed in this embodiment is the minimum value among the multiple speed limit values. Thus, on the premise of ensuring driving safety, the battery temperature is adjusted by adjusting the driving speed of the target vehicle, and the practicability is stronger.

[0103] In step S330, in response to the guiding vehicle speed being less than or equal to the restricted vehicle speed, send a first prompt message. The first prompt message is used to prompt the target vehicle to drive to the target charging pile at the guiding vehicle speed.

[0104] In step S340, in response to the guiding vehicle speed being greater than the restricted vehicle speed, send a second prompt message. The second prompt message is used to prompt the target vehicle to turn on the battery heating device and drive to the target charging pile at a preset driving speed at the same time, and the preset driving speed is less than or equal to the restricted vehicle speed.

[0105] Optionally, the preset driving speed in this embodiment can be a driving speed less than the restricted vehicle speed. The difference between the preset driving speed and the restricted vehicle speed can be adjusted according to actual driving experience or actual driving conditions.

[0106] After determining the guiding vehicle speed, the technical solution of this embodiment determines the relationship between the guiding vehicle speed and the restricted vehicle speed. When the guiding vehicle speed is less than or equal to the restricted vehicle speed, the target vehicle is made to travel to the target charging pile at the guiding vehicle speed, so that the target vehicle can reach the preset temperature when it arrives at the target charging pile, maximizing the charging efficiency of the target vehicle, shortening the charging time of the target vehicle, and reducing the waiting cost of the vehicle driver; or when the guiding vehicle speed is greater than the restricted vehicle speed, the target vehicle travels to the target charging pile at the preset driving speed and turns on the battery heating device, so that while driving safely and in accordance with regulations, the temperature of the vehicle battery can be increased as much as possible, improving the charging efficiency of the vehicle battery, reducing the charging time after the target vehicle arrives at the target charging pile, and reducing the waiting cost of the vehicle driver.

[0107] Optionally, before obtaining the vehicle information and charging pile information of the target vehicle, the information interaction method of the server side in this embodiment further includes: receiving a reservation request of the target vehicle. The reservation request includes vehicle information. Thus, after the server receives the reservation request of the target vehicle, it determines the guiding vehicle speed of the target vehicle according to the reservation request and the obtained vehicle information and charging pile information, and prompts the target vehicle with the vehicle speed required for heating the vehicle battery according to the guiding vehicle speed.

[0108] Optionally, the information interaction method of the server side in this embodiment further includes: obtaining the power information of the target vehicle, where the power information is used to represent the battery power of the target vehicle; and in response to the battery power being less than the preset power, sending the charging pile information to the target vehicle. Thus, the server determines whether the target vehicle needs to be charged and battery heated according to the power information, and at the same time obtains the charging pile information sent by the target vehicle, which is convenient for the server to determine the route of the target vehicle to reach the target charging pile according to the vehicle information and the target charging pile information, providing convenience for the target vehicle to reach the target charging pile.

[0109] Figure 5 It is a schematic diagram of the information interaction method of the vehicle side. As Figure 5 shown, the information interaction method of this embodiment includes:

[0110] In step S510, send vehicle information. The vehicle information includes vehicle position information and the initial battery temperature.

[0111] Optionally, the vehicle information in this embodiment further includes vehicle identification information. The vehicle identification information corresponds to the target vehicle one by one, and each vehicle has a uniquely corresponding vehicle identification information.

[0112] In step S520, receive the prompt of the vehicle speed required for heating the vehicle battery sent by the server.

[0113] In this embodiment, the vehicle terminal receives a prompt of the vehicle speed required to heat the vehicle battery sent by the server. When the target vehicle travels at the above vehicle speed, the heat generated by the vehicle's travel can be used to increase the temperature of the vehicle battery, and the battery temperature of the target vehicle can be quickly increased from the initial battery temperature to a preset temperature, thereby improving the charging efficiency of the target vehicle after reaching the target charging pile, shortening the charging time, and reducing the driver's waiting cost.

[0114] Optionally, receiving the prompt of the vehicle speed required to heat the vehicle battery sent by the server in this embodiment includes the following steps.

[0115] In step S521, receive the first prompt message. The first prompt message is used to prompt the vehicle to travel to the target charging pile at the guiding vehicle speed.

[0116] In step S522, receive the second prompt message. The second prompt message is used to prompt the vehicle to turn on the battery heating device and at the same time travel to the target charging pile at a preset driving speed, and the preset driving speed is less than or equal to the restricted vehicle speed.

[0117] It should be noted that step S521 and step S522 in this embodiment are executed in parallel. When the guiding vehicle speed is less than or equal to the restricted vehicle speed, the vehicle terminal will receive the first prompt message. When the guiding vehicle speed is greater than the restricted vehicle speed, the vehicle terminal will receive the second prompt message.

[0118] Optionally, the sending of the vehicle information and the receiving of the first prompt message and the second prompt message in this embodiment are all realized through the terminal device of the vehicle terminal. The terminal device here can be a terminal held by the vehicle driver, or an in-vehicle terminal or a detachable terminal installed inside the vehicle for the vehicle driver to receive and view information. When the vehicle driver receives the first prompt message, drive the target vehicle to the target charging pile at the guiding vehicle speed, so that during the target vehicle's travel to the target charging pile, the heat generated during the vehicle's travel can be used to heat the vehicle battery, thereby enabling the battery temperature of the target vehicle to be heated to the preset temperature when it reaches the target charging pile. Or, when the vehicle driver receives the second prompt message, drive the target vehicle to the target charging pile at the preset driving speed, so that during the vehicle's travel to the target charging pile, the heat generated during the vehicle's travel can be used to heat the vehicle battery, which is beneficial to improving the charging efficiency of the target vehicle after traveling to the target charging pile, reducing the charging time, and reducing the vehicle driver's waiting cost.

[0119] Optionally, before sending the vehicle information, the vehicle - side information interaction method in this embodiment further includes: sending a reservation request. The reservation request includes vehicle information. Thus, the vehicle information and charging requirements are sent to the server in a reservation manner. After receiving the reservation request of the target vehicle, the server determines the guiding vehicle speed of the target vehicle according to the reservation request, the obtained vehicle information, and charging pile information, and prompts the target vehicle with the vehicle speed required for heating the vehicle battery according to the guiding vehicle speed.

[0120] Furthermore, the information interaction method in this embodiment further includes: sending power information and receiving charging pile information. The power information is used to represent the remaining battery power of the vehicle. The charging pile information includes the target charging pile location information. Thus, based on the power information sent by the target vehicle, the server determines whether the target vehicle needs to be charged and battery - heated, and at the same time obtains the charging pile information sent by the target vehicle, which is convenient for the server to provide battery - heating services for the target vehicle according to the actual power information of the vehicle, giving priority to meeting the charging requirements of vehicles with lower battery power, and at the same time helping to improve the utilization efficiency of the charging piles.

[0121] The technical solution of the embodiment of the present invention sends vehicle information through the terminal device on the vehicle - side and receives the first prompt information or the second prompt information. When the vehicle - side receives the first prompt information, it prompts the vehicle driver to drive the target vehicle to the target charging pile at the guiding vehicle speed, and during the process of the target vehicle arriving at the target charging pile, the vehicle battery is heated by the heat generated during vehicle driving, so that the battery temperature of the target vehicle can be heated to the preset temperature when it arrives at the target charging pile, maximizing the temperature rise of the vehicle battery, thereby improving the charging efficiency of the vehicle battery after arriving at the target charging pile, reducing the charging time, and saving the waiting cost of the vehicle driver. At the same time, compared with the process of heating the battery only by the heat generated by battery discharge during driving without a guiding vehicle speed, since the driving speed is faster under the guiding vehicle speed, the time required for battery temperature rise is shorter, and the battery capacity consumed for battery temperature rise is less, thus saving the battery capacity during the battery temperature - rising process. When the vehicle - side receives the second prompt information, it prompts the vehicle driver to drive the target vehicle to the target charging pile at the preset driving speed, so as to heat the vehicle battery by the heat generated during vehicle driving during the process of the vehicle arriving at the target charging pile, which is conducive to accelerating the battery temperature - rising process, improving the charging efficiency of the target vehicle after arriving at the target charging pile, reducing the charging time, and reducing the waiting cost of the vehicle driver. At the same time, compared with the traditional process of heating the battery by a battery - heating device, since the power supply of the battery to the battery - heating device is reduced, the battery capacity required for discharging during the battery temperature - rising process can be reduced, thus saving the battery capacity during the battery temperature - rising process.

[0122] Figure 6It is a schematic diagram of the information interaction process. As Figure 6 shown, the information interaction system in this embodiment includes a cloud platform 1 and a vehicle terminal 2. Among them, a communication connection is established between the cloud platform 1 and the vehicle terminal 2 through a network. The cloud platform 1 corresponds to an online car-hailing service platform and is configured with a server. The vehicle terminal 2 can be a terminal held by a vehicle driver, or an in-vehicle terminal or a detachable terminal installed inside the vehicle for the vehicle driver to receive and view information. In addition, the following processes are included during the information interaction process.

[0123] In step S610, the vehicle terminal sends a reservation request and power information.

[0124] In this embodiment, the reservation request includes vehicle information. The vehicle information includes vehicle identification information, vehicle location information, and initial battery temperature. The power information is used to represent the remaining battery power of the target vehicle.

[0125] In step S620, the cloud platform obtains vehicle information and charging pile information.

[0126] Optionally, the vehicle information obtained by the cloud platform in this embodiment is consistent with the vehicle information in the reservation request sent by the vehicle terminal.

[0127] Optionally, the charging pile information in this embodiment includes target charging pile location information. The target charging pile can be a charging pile within a preset distance range obtained by the vehicle terminal according to the current vehicle location information, or a charging pile obtained by the cloud platform from the server according to the location information of the target vehicle. And there can be multiple charging piles obtained by the cloud platform from the server. The cloud platform can sort each charging pile according to location or usage performance, and select the charging pile with the best location or the strongest usage performance as the target charging pile.

[0128] Optionally, when the target charging pile is determined by the vehicle terminal, this embodiment executes step S640 after step S620 and does not need to execute step S630. When the target charging pile is determined by the cloud platform, this embodiment continues to execute the subsequent steps S630 - S660 after step S620.

[0129] In step S630, the cloud platform sends the charging pile information to the vehicle terminal.

[0130] Optionally, after the cloud platform in this embodiment obtains the vehicle information and charging pile information of the target vehicle, in response to the battery power of the target vehicle being less than the preset power, the charging pile information is sent to the vehicle terminal. Thus, by providing battery heating service for the target vehicle according to the actual vehicle power information, the charging requirements of vehicles with lower battery power can be preferentially met, and the applicability is higher.

[0131] In step S640, the cloud platform determines the guiding vehicle speed.

[0132] Optionally, the vehicle information in this embodiment further includes vehicle identification information. The vehicle identification information adopts the unique identification information corresponding to the vehicle model to which the target vehicle belongs.

[0133] Optionally, after the cloud platform receives the feedback of the charging pile information from the vehicle terminal, it executes step S640. Moreover, when determining the guiding vehicle speed of the target vehicle, the cloud platform first obtains the historical operation data corresponding to the target vehicle model based on the vehicle identification information, and determines the temperature rise relationship table of the target vehicle based on the historical operation data. After determining the temperature rise relationship table corresponding to the target vehicle, it determines the driving distance of the target vehicle based on the vehicle position information of the target vehicle and the position information of the target charging pile, then determines the heating temperature difference based on the initial battery temperature and the preset temperature, and finally queries the temperature rise relationship table to select the vehicle speed range that simultaneously satisfies the form distance and the heating temperature difference from the temperature rise relationship table, and determines the intermediate vehicle speed in the vehicle speed range as the guiding vehicle speed for the target vehicle to reach the target charging pile.

[0134] Optionally, the operations of obtaining the historical operation data corresponding to the same vehicle model and determining the corresponding temperature rise relationship table based on the historical operation data in this embodiment only need to be executed once when initially determining the temperature rise relationship table of the above vehicle model. After determining the temperature rise relationship tables corresponding to each vehicle model, store each temperature rise relationship table, and directly call the corresponding temperature rise relationship table when it is necessary to determine the guiding vehicle speed of the same type of target vehicle next time. Thus, the repeated execution of the same step is reduced, which is beneficial to improving the information interaction efficiency and further enhancing the use experience of the vehicle driver or passenger.

[0135] In step S650, the cloud platform sends the vehicle speed required for the target vehicle to heat the vehicle battery to the vehicle terminal.

[0136] When the cloud platform in this embodiment sends the vehicle speed required for the target vehicle to heat the vehicle battery to the vehicle terminal, it will judge the relationship between the guiding vehicle speed and the restricted vehicle speed. When the guiding vehicle speed is less than or equal to the restricted vehicle speed, the cloud platform sends the first prompt information to the vehicle terminal to prompt the vehicle driver to drive the target vehicle to the target charging pile according to the guiding vehicle speed. When the guiding vehicle speed is greater than the restricted vehicle speed, the cloud platform sends the second prompt information to the vehicle terminal to prompt the vehicle driver to drive the target vehicle to the target charging pile according to the preset driving speed.

[0137] Optionally, when a battery heating device is configured in the target vehicle, the second prompt message is further used to prompt the target vehicle to turn on the battery heating device to heat the battery, so that under the combined action of the predetermined driving speed of the target vehicle and the battery heating device, the temperature of the vehicle battery of the target vehicle can reach the preset temperature when the target vehicle arrives at the target charging pile, avoiding the limitation of the vehicle speed limit on the battery heating process. At the same time, compared with the conventional heating that solely relies on the battery heating device, the overall heating speed is faster.

[0138] Furthermore, when the battery heating device in the vehicle is also used to provide heating for the passenger compartment or other heating requirements, to ensure that the vehicle battery can be heated to the preset temperature when the guiding vehicle speed is greater than the restricted vehicle speed, the battery heating device in this embodiment preferentially provides heating for the vehicle battery and reduces or stops the heating for the passenger compartment or other heating requirements.

[0139] In step S660, the vehicle terminal adjusts the driving speed of the target vehicle to heat the vehicle battery.

[0140] In this embodiment, after receiving the first prompt message, the vehicle terminal prompts the vehicle driver to adjust the driving speed of the target vehicle to the guiding vehicle speed and drive the target vehicle to the target charging pile at the guiding vehicle speed.

[0141] Optionally, in this embodiment, after receiving the second prompt message, the vehicle terminal prompts the vehicle driver to turn on the battery heating device and adjust the driving speed of the target vehicle to the preset driving speed, so that the target vehicle drives the target vehicle to the target charging pile at the preset driving speed.

[0142] The technical solution of this embodiment sends a reservation request and power information through the vehicle terminal. After obtaining the vehicle information and charging pile information, the cloud platform sends the charging pile information to the vehicle terminal, determines the guiding vehicle speed, and sends the vehicle speed required to prompt the target vehicle to heat the vehicle battery to the vehicle terminal. Thus, through the interaction process between the cloud platform and the vehicle terminal, when the target vehicle drives to the target charging pile at the guiding vehicle speed or the predetermined driving speed, the temperature of the vehicle battery is increased by adjusting the driving speed of the vehicle. In this way, not only can the temperature of the vehicle battery reach the preset temperature when the target vehicle arrives at the target charging pile, improving the charging efficiency of the vehicle battery, shortening the charging time of the vehicle battery, reducing the waiting cost of the vehicle driver, but also saving battery power.

[0143] Figure 7 is another schematic diagram of the information interaction process. As Figure 7As shown in the figure, the information interaction system in this embodiment includes a charging platform 3, a cloud platform 1, and a vehicle terminal 2. Among them, communication connections are established among the cloud platform 1, the vehicle terminal 2, and the charging platform 3 through a network. The cloud platform 1 corresponds to an online car-hailing service platform. The vehicle terminal 2 can be a terminal held by a vehicle driver, or an in-vehicle terminal or a detachable terminal installed inside the vehicle for the vehicle driver to receive and view information. In addition, the following processes are included during the information interaction process.

[0144] In step S710, the charging platform sends charging pile information to the vehicle terminal.

[0145] Optionally, in this embodiment, the charging platform acquires vehicle information and corresponding power information, and the power information is used to represent the remaining battery power of the vehicle. When it is detected that the battery power of the vehicle is in a low power state, charging pile information is sent to the target vehicle in the corresponding low power state.

[0146] Optionally, the battery power in this embodiment can be reflected by the state of charge of the battery (i.e., the SOC value). When the battery power of the vehicle is less than the preset power value, the vehicle is considered to be in a low power state. Specifically, the preset power value in this embodiment can be set to an SOC value of 30%. It should be understood that the preset power value in this embodiment can also be set according to the specific power consumption of the vehicle, the distribution of charging piles, or other influencing factors to meet the fast charging requirements of different vehicles.

[0147] In step S720, the vehicle terminal acquires the charging pile information and sends a reservation request to the charging platform.

[0148] Optionally, the target charging pile in this embodiment can be the best charging pile selected by the charging platform according to the actual situation of the target vehicle, or determined by the vehicle terminal. After determining the target charging pile, the navigation software is used to plan the navigation routes between the current position of the vehicle and each target charging pile. After the vehicle terminal confirms the current target charging pile, the vehicle terminal sends a reservation request to the charging platform.

[0149] In step S730, the charging platform sends the reservation request and the charging pile information to the cloud platform.

[0150] In this embodiment, after the charging platform acquires the reservation request sent by the vehicle terminal, it sends the reservation request and the charging pile information to the cloud platform at the same time. Among them, the reservation request includes vehicle information. The charging pile information includes the location information of the target charging pile. The vehicle information includes vehicle identification information, vehicle location information, and the initial battery temperature.

[0151] In step S740, the cloud platform acquires the vehicle information and the charging pile information, and determines the guiding vehicle speed of the target vehicle according to the acquired vehicle information and charging pile information.

[0152] In step S750, the cloud platform sends to the vehicle side the vehicle speed required to prompt the target vehicle to heat the vehicle battery.

[0153] In step S760, the vehicle side adjusts the driving speed of the target vehicle to heat the vehicle battery.

[0154] Optionally, the steps of determining the guiding vehicle speed of the target vehicle, prompting the vehicle speed required for the target vehicle to heat the vehicle battery, and adjusting the driving speed of the target vehicle to heat the vehicle battery in this step are the same as those above, and will not be elaborated here.

[0155] The technical solution of this embodiment sends the charging pile information to the vehicle side through the charging platform. After the vehicle side obtains the charging pile information, it sends a reservation request to the charging platform. After the charging platform obtains the reservation request from the vehicle side, it sends the reservation request and the charging pile information to the cloud platform. The cloud platform obtains the vehicle information and the charging pile information, determines the guiding vehicle speed of the target vehicle based on the obtained vehicle information and the target charging pile location information, and sends to the vehicle side the vehicle speed required to prompt the target vehicle to heat the vehicle battery based on the guiding vehicle speed. Finally, the vehicle side adjusts the driving speed of the target vehicle according to the received first prompt information or second prompt information to heat up the vehicle battery. Thus, through the interaction process among the cloud platform, the charging platform, and the vehicle side, the target vehicle travels to the target charging pile at the guiding vehicle speed or the predetermined driving speed, and the vehicle battery is heated by the heat generated during vehicle driving. While saving battery power, the temperature of the vehicle battery when the target vehicle reaches the target charging pile can reach the preset temperature, thereby improving the charging efficiency of the vehicle battery, shortening the vehicle battery charging time, and further reducing the waiting cost of the vehicle driver.

[0156] Figures 8 - 11 It is a schematic diagram of the interaction interface on the vehicle side. As Figure 8 shown, when the vehicle side makes a charging reservation, the vehicle information, power information, and reservation control are displayed on the reservation interface. The vehicle information includes vehicle identification information, vehicle location information, and the initial battery temperature. The power information shows the remaining power of the target vehicle. When the user clicks the send reservation control, the vehicle side sends the vehicle information to the cloud platform.

[0157] As Figure 9 shown, after the cloud platform obtains the charging pile information and determines the guiding vehicle speed of the target vehicle, it sends the charging pile information and the prompt of the vehicle speed required to heat the vehicle battery to the vehicle side respectively, and the detailed heating plan of the target battery is displayed on the heating plan display interface on the vehicle side. The displayed content includes vehicle identification information, vehicle location information, target charging pile location information, initial battery temperature, preset temperature, vehicle driving distance, and recommended vehicle speed.

[0158] AsFigure 10 As shown, after the vehicle terminal confirms the above battery heating solution, the vehicle terminal will display a navigation interface for the target vehicle to drive from the current position to the target charging pile. At the same time, for the convenience of guiding the vehicle driver to drive, the navigation interface in this embodiment also displays the recommended vehicle speed, the current battery temperature, the current vehicle position information, and the position information of the target charging pile.

[0159] As Figure 11 shown, when the temperature of the vehicle battery has been heated from the initial battery temperature to the preset battery temperature, it indicates that the battery heating is completed. At this time, the heating completion interface of the vehicle terminal will display the current battery temperature, the current battery power, the current vehicle position information, and the end heating control. When the vehicle driver clicks the end heating control, it indicates that the current battery heating process ends.

The determination unit 122 is used to determine the guiding vehicle speed for the target vehicle to reach the target charging pile based on the vehicle information and the charging pile information. When the target vehicle travels to the target charging pile at the guiding vehicle speed, the battery temperature rises from the initial battery temperature to the preset temperature, and the battery charging efficiency at the preset temperature is higher than the battery charging efficiency at the initial battery temperature. The prompt unit 123 is used to prompt the target vehicle with the vehicle speed required for heating the vehicle battery according to the guiding vehicle speed.
