[0045] The following describes the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and the features in the embodiments can be combined with each other without conflict. It should also be understood that the terms used in the embodiments of the present invention are intended to describe specific implementation schemes, rather than to limit the scope of protection of the present invention. The test methods for which specific conditions are not specified in the following examples are usually carried out under conventional conditions or under the conditions recommended by the manufacturers.

[0046] When numerical ranges are given in the embodiments, it should be understood that unless otherwise specified in the present invention, both endpoints of each numerical range and any value between the two endpoints can be selected. Unless otherwise defined, all technical and scientific terms used in the present invention are in accordance with the prior art mastery of the technicians in the field and the description of the present invention, and any equipment and materials of the prior art similar or equivalent to the equipment and materials in the embodiments of the present invention can also be used to implement the present invention.

[0047] With the continuous advancement of electric vehicle technology, the demand for higher performance such as the range of electric vehicles is also increasing year by year. Taking the improvement of the range of electric vehicles as an example, the current methods for improving the range of electric vehicles in the industry mainly involve increasing battery capacity and improving battery energy density. Among them, the method of increasing battery capacity is mainly to provide more electrical energy by expanding the size and energy storage capacity of the battery, thereby extending the driving distance of the electric vehicle. The method of improving battery energy density is mainly to improve the battery's energy storage efficiency and power output density, store more energy under the same volume and weight, and achieve a longer range under limited battery capacity.

[0048] However, this adjustment method of the vehicle battery also has certain risks, which can easily lead to abnormal conditions such as overcharging and discharging of the vehicle battery. For example, high-capacity and high-density batteries may lead to accelerated attenuation and even cause spontaneous combustion problems. And during the use of the vehicle, if the battery is overcharged and discharged, it will seriously damage the consistency of the battery, accelerate the battery loss rate and shorten the battery life. In addition, excessive charging and discharging will also cause excessive energy stored in the battery, increasing the risk of spontaneous combustion. Each charge and discharge will cause irreversible damage to the battery, and this damage will have a cumulative effect. The more times, the more significant the impact on battery performance. In addition, in actual application, consumers may intentionally or unintentionally overcharge or over-discharge the battery due to their lack of understanding of the battery maintenance characteristics, which will seriously affect the battery life and increase the risk of thermal runaway.

[0049] In the related technologies, vehicles either have no adjustment measures for battery abnormalities such as overcharging and discharging, or the adjustment measures are relatively delayed. The real-time management of vehicle single batteries is not high, which will lead to increased loss of vehicle batteries and shorten the battery life. At the same time, there are also certain safety risks, such as spontaneous combustion of vehicle batteries.

[0050] In view of the above technical problems, the utility model inventor found in the process of studying the vehicle battery management system based on satellite communication that the vehicle can realize data interaction with the cloud platform based on satellite communication. Satellite communication can improve the efficiency and real-time performance of data transmission and ensure the reliable transmission of data. At the same time, the vehicle can use the powerful computing power of the cloud platform to perform data statistics and analysis to realize the real-time and safe management of the power of the vehicle's single battery. Specifically, after the vehicle is locked due to the exhaustion of the free power interval of the single battery in the battery assembly, it receives the unlocking information sent by the cloud platform through satellite communication, which is used to indicate that the user has paid the fee for the paid power interval of the single battery; then the vehicle can unlock the use of the single battery so that the single battery can continue to discharge. In this way, the vehicle configures the power of the single battery in the battery assembly into a free power interval for free use by the user and a paid power interval for unlocking and use, and the vehicle and the cloud platform transmit and interact the unlocking information through satellite, which can improve the efficiency and reliability of data transmission, realize the online real-time management of the power of the vehicle's single battery, avoid abnormal situations such as excessive charging and discharging of the vehicle battery, reduce battery loss, and extend the service life of the battery. At the same time, it can also reduce the safety risk of the vehicle battery and ensure the safety of the vehicle and the user.

[0051] For example, Figure 1 This is a schematic diagram of the application scenario of the vehicle battery management system based on satellite communication provided in this application. Figure 1As shown, the application scenario of the solution provided by the present application includes a vehicle 101, a satellite 102, and a cloud platform 103. The vehicle 101 collects consistency information of the battery assembly, and then uploads the consistency information to the satellite 102; the satellite 102 receives the consistency information uploaded by the vehicle 101, and sends the consistency information to the cloud platform 102; the cloud platform 102 generates the battery management information of the vehicle based on the consistency information sent by the satellite 102, and sends the battery management information to the satellite 102; the satellite 102 receives the battery management information returned by the cloud platform 103, and sends the battery management information to the vehicle 101, and the vehicle 101 can implement safety management for the battery assembly based on the battery management information.

[0052] In addition, when the free power interval of a single battery in the battery assembly of vehicle 101 is exhausted and locked, vehicle 101 receives unlocking information sent by cloud platform 103 via satellite 102 communication. Vehicle 101 can unlock the use of the single battery, allowing the single battery to continue to discharge, meet the user's power needs, and ensure the safety and stability of the vehicle battery assembly.

[0053] Figure 2 The schematic diagram of the architecture of the vehicle battery management system based on satellite communication provided in this application is as follows: Figure 2 As shown, when the free power interval of the single battery in the vehicle battery assembly is exhausted and locked, the vehicle can display the paid power usage confirmation information through the output device. After receiving the paid power usage confirmation information, the user needs to choose whether to pay the fee according to actual needs. When the user completes the payment operation, the payment system will generate payment confirmation information and send the payment confirmation information to the cloud platform through the network. After receiving the payment confirmation information, the cloud platform can parse and verify to confirm the user's payment status. After confirming that the user has completed the payment, the cloud platform will generate unlocking information accordingly. After that, the cloud platform can send the unlocking information to the target satellite, and the target satellite will send the unlocking information to the vehicle's on-board satellite terminal, so that the vehicle can unlock the single battery through the control unit and the battery management unit, so that the single battery can continue to discharge.

[0054] In addition, the vehicle and the cloud platform can also exchange consistency information based on satellite communication, further realizing real-time safety management of vehicle battery components. Specifically, the vehicle control unit collects the consistency information of the battery components through the battery management unit according to a preset period, and then the vehicle sends the consistency information to the target satellite through the on-board satellite terminal. After receiving the consistency information, the target satellite sends the consistency information to the cloud platform of the cloud server. The cloud platform receives the consistency information and generates battery management information based on the consistency information. The cloud platform then returns the battery management information to the target satellite, and the target satellite receives the battery management information and forwards the battery management information to the on-board satellite terminal. The vehicle control unit can realize real-time safety management of the vehicle battery components based on the battery management information to ensure the safety and stability of the vehicle battery components.

[0055] The vehicle battery management system based on satellite communication in the present application includes a vehicle, a target satellite and a cloud platform; wherein the vehicle is used to receive unlocking information sent by the cloud platform through satellite communication after the free power interval of a single battery in the vehicle battery assembly is exhausted and locked, and the unlocking information is used to indicate that the user has paid the fee for using the paid power interval of the single battery; the use of the single battery is unlocked so that the single battery continues to discharge; wherein the power of each single battery in the battery assembly is configured as a free power interval for free use by the user and a paid power interval for unlocking and use;

[0056] The target satellite is used to receive unlocking information sent by the cloud platform, the unlocking information is used to indicate that the user has paid for the paid power interval of the single battery in the vehicle battery assembly, and send the unlocking information to the vehicle;

[0057] The cloud platform is used to generate unlocking information after determining that the user has paid for the use of the paid power range of the single battery in the vehicle battery assembly. The unlocking information is used to indicate that the user has paid for the use of the paid power range of the single battery, and the unlocking information is sent to the vehicle via satellite communication.

[0058] Figure 3 This is a flow chart of the first embodiment of the vehicle battery management system based on satellite communication provided by this application. Figure 3 As shown, the vehicle battery management system based on satellite communication is used for:

[0059] S301: After the free power interval of a single battery in a vehicle battery assembly is exhausted and locked, receiving unlocking information sent by a cloud platform via satellite communication, the unlocking information is used to indicate that the user has paid for the paid power interval of the single battery.

[0060] S302: Unlocking the use of the single cell battery so that the single cell battery continues to discharge; wherein the power level of each single cell battery in the battery assembly is configured into a free power level range for free use by the user and a paid power level range for unlocking and use that requires payment.

[0061] In the present application, the vehicle battery assembly can be configured inside the electric vehicle as its core energy device to provide stable power for the vehicle. The vehicle battery assembly includes at least one single battery and may also include a battery management unit connected to the at least one single battery. The battery management unit is used to manage the single battery and realize corresponding detection, power management and control functions.

[0062] Among them, each single cell can be any one of the following batteries: lithium battery, lithium iron phosphate battery or solid-state battery. Among them, lithium batteries have high energy density and light weight, and are suitable for electric vehicle applications with high energy density and weight requirements. Lithium iron phosphate batteries have higher safety and stability, and are suitable for application scenarios that require higher safety. As an emerging technology, solid-state batteries have achieved a good balance between high energy density and safety, providing more reliable and lasting power support for electric vehicles. By selecting the appropriate type of single cell, the battery assembly can meet the needs of different vehicles and users, while providing more flexible and diversified energy solutions.

[0063] According to different voltage value intervals, each single battery includes a preset free power interval and a paid power area. In the free power interval, users can freely use the energy stored in the battery to meet the needs of daily short-distance travel. In the paid power interval, users can unlock additional power by paying a certain fee to cope with long-distance travel or urgent charging. The preset paid power interval refers to a power range pre-set in the battery use management unit. When the remaining power of the single battery is within this range, the user needs to pay the corresponding fee to continue to use the power. The setting of this interval is usually determined according to the needs of the user and the strategy of the service provider. The upper and lower limits of the interval can be determined according to the battery capacity, the model of the tram or the personal needs of the user. For example, the preset paid power interval can be set to require payment when the remaining power of the battery is less than 30%. When the remaining power of the battery exceeds this interval, the user can freely use the power without paying additional fees. However, once the power enters the preset payment interval, the user needs to confirm and pay the corresponding fee before continuing to use the battery.

[0064] Specifically, when the remaining power of a single battery reaches the set paid power interval, the vehicle can lock the paid power interval of the single battery through the battery management unit to prevent the user from continuing to consume power and avoid excessive discharge of the battery. At the same time, the battery management unit will push the paid power usage confirmation information to the user, including providing relevant fee information for paying for the use of power in this interval, so that the user can confirm and pay the corresponding fees. At this time, the user can choose to pay additional fees to unlock the paid power interval and obtain additional power support when necessary according to actual needs. When the user pays the corresponding fee, the cloud platform will detect that the user has paid in full, can generate unlocking information, and send the unlocking information to the vehicle based on satellite communication.

[0065] When the remaining power of a single battery reaches the preset payment power interval, the battery management unit can lock the use of the single battery by software or hardware. Specific locking operations may include software-controlled locking, hardware power-off locking, and remote-controlled locking. Among them, software-controlled locking refers to monitoring and identifying the remaining power of a single battery through a software program in the battery management unit. Once it is detected that the power of a single battery enters the preset payment interval, the software will send an instruction to the battery management unit to request that the single battery be locked. In this way, the single battery can no longer supply power to the vehicle, thereby limiting the user's continued use. Hardware power-off locking refers to locking a single battery through a hardware device. For example, a switch or circuit breaker can be set in the battery management unit. When the power reaches the preset interval, the battery management unit will automatically cut off the connection between the battery and the vehicle, so that the battery cannot output power, thereby achieving a locked state. Remote control locking means that when the power of a single battery reaches the preset interval, the battery management unit can be remotely controlled through the network to achieve a battery locking operation.

[0066] In the present solution, it should be understood that the monitoring of the remaining power can be determined by the effective voltage of the battery. The battery management unit or control unit obtains the real-time voltage of each single cell and determines whether to lock or unlock the use of the battery based on the voltage value and the effective voltage range corresponding to the preset free power interval and the effective voltage range corresponding to the paid power interval.

[0067] The vehicle battery management system based on satellite communication provided in this embodiment can effectively lock the single battery, ensuring that the user needs to pay a fee to continue to use the power when the paid power range is reached. This locking mechanism can encourage users to save power and use resources reasonably, avoid overcharging and discharging of vehicle single batteries, reduce battery loss, extend battery life, and promote the sustainable development of the electric vehicle market.

Of course, the consistency information may also include other types of information, which may be flexibly set based on actual needs, and the present application does not limit this.

[0072] S402: Send consistency information to the cloud platform based on satellite communication.

[0073] In this application, satellite communication may refer to a communication transmission method based on satellites. A cloud platform refers to a computing platform deployed in the cloud, such as a cloud server, which can realize the statistics, processing and calculation of operating data and generate corresponding control instructions. Specifically, after the vehicle obtains the consistency information of the battery assembly, it can upload the consistency information to the target satellite, and the target satellite forwards the consistency information to the cloud platform to achieve efficient, reliable and accurate transmission of vehicle data.

[0074] S403: Receive battery management information returned by the cloud platform based on satellite communication, and manage the battery components according to the battery management information.

[0075] In this application, battery management information may refer to control management instructions for battery components issued by the cloud platform, which may include fault information of the battery components and target management operations (or management strategies), etc. After receiving the consistency information of the battery components sent by the vehicle based on satellite communication, the cloud platform can determine whether there is an abnormal fault in the battery component based on the consistency information, and determine the corresponding management operation for the abnormal fault situation, and then generate battery management information. The cloud platform can return the battery management information to the vehicle via satellite communication. The vehicle can receive the battery management information and perform safe management of the battery components based on the battery management information through the control unit and the battery management unit, etc., to ensure the safety and normal operation of the vehicle battery.

[0076] In the vehicle battery management system based on satellite communication provided in this embodiment, the vehicle detects the consistency information of the battery assembly, and then sends the consistency information to the cloud platform based on satellite communication; then the vehicle receives the battery management information returned by the cloud platform based on satellite communication, and manages the battery assembly according to the battery management information. In this way, the vehicle exchanges data with the cloud platform through satellite communication, which can ensure the real-time and accuracy of vehicle battery management, avoid abnormal conditions of the vehicle battery, reduce battery loss, extend battery life, and ensure the safety of the vehicle and users (consumers, drivers, etc.).

[0077] Figure 5 The flowchart of the third embodiment of the vehicle battery management system based on satellite communication provided in the application is as follows. Figure 5 As shown, the vehicle battery management system based on satellite communication is used for:

[0078] S501: According to a preset time period, the battery management unit of the battery assembly detects consistency information; the consistency information includes single cell consistency information, consistency information of the free power interval and consistency information of the paid power interval.

[0079] In the present application, the preset time period may refer to a preset data detection period, such as 100 milliseconds, 200 milliseconds or 500 milliseconds, etc., which may be flexibly set based on the data collection performance of the vehicle, and the present application does not limit this. The battery management unit may be used to detect various real-time states of a single battery.

[0080] The consistency information of the single cell battery may include at least one of the power information, temperature information, resistance information, voltage information and current information of each single cell battery. Specifically, the power information may refer to the total power, used power, remaining power and other information of the single cell battery, which can be used to determine whether the capacity of the single cell battery is abnormal or whether there is an abnormality in the use of power. Temperature information may refer to the real-time temperature information of the single cell battery, which can be used to determine whether the single cell battery has abnormal conditions such as overheating. Voltage information and current information can provide accurate data about the power of the single cell battery, which can be used to determine the actual performance of the operating status of the single cell battery. Resistance information may refer to the internal resistance information of the single cell battery, which can be used to determine whether there is something inside the single cell battery, and can be used to determine the internal resistance of the single cell battery. Of course, the consistency information may also include other types of information, which is not limited in this application.

[0081] In this step, the vehicle can periodically detect the consistency information corresponding to each single battery through the battery management unit according to a preset time period, and the detection can be implemented based on the sensor corresponding to each single battery. In this way, the vehicle can quickly obtain the real-time status of the single battery through periodic detection of consistency information, thereby improving the real-time performance of subsequent battery management.

[0082] S502: Send consistency information to the target satellite through the vehicle-mounted satellite terminal, so that the target satellite sends the consistency information to the cloud platform.

[0083] In this application, the vehicle-mounted satellite terminal may refer to a satellite communication terminal installed in the vehicle, which can communicate wirelessly with the target satellite. Specifically, after the vehicle obtains the consistency information through the battery management unit, it can send the consistency information to the target satellite through the vehicle-mounted satellite terminal. After receiving the consistency information sent by the vehicle-mounted satellite terminal, the target satellite can send the consistency information to the cloud platform. In this way, data transfer and transmission between the vehicle and the cloud platform based on the target satellite can ensure efficient, reliable and accurate data transmission.

[0084] S503: Receive battery management information returned by the cloud platform based on satellite communication.

[0085] S504: Controlling the working state of a single cell in the battery assembly according to the battery management information; the working state of the single cell includes a locked state, an unlocked state, a charging state or a discharging state.

[0086] In the embodiments of the present application, the working state of a single cell may refer to the current operating state of the single cell, which may specifically include a locked state, an unlocked state, a charging state, or a discharging state. Among them, the locked state may refer to that the connection between the single cell and the vehicle is in a cut-off state, and the single cell cannot output power. The unlocked state may refer to that the single cell and the vehicle are in a normal connection state, and the single cell can output power normally. The charging state may refer to that the single cell is in the charging process; the discharging state may refer to that the single cell is in the discharging process. Of course, the working state may also include other states, which are not limited in the present application.

[0087] In this step, the vehicle receives the battery management information returned by the cloud platform based on satellite communication, and then can control the working state of the single battery in the battery assembly based on the battery management information. Specifically, the vehicle can adjust the working state of the single battery with a fault condition based on the target management operation in the battery management information, and can switch the working state, or maintain the same working state but adjust the specific working data (such as adjusting the charging and discharging rate) to achieve safe management of the battery assembly. Exemplarily, for single batteries with aging, the vehicle can adjust them to a locked state; for single batteries with overcharge, the vehicle can switch them from a charging state to a discharging state; for single batteries with over-high temperatures, the vehicle can adjust the discharge rate of the single battery in the discharging state.

[0088] In this application, the vehicle controls the working status of the vehicle's single battery according to the battery management information, and can take corresponding safety management measures for faulty batteries or abnormal batteries, thereby improving the real-time and effectiveness of battery safety management, and ensuring the safety and stability of the entire battery assembly of the vehicle.

[0092] Figure 6 This is a flow chart of the fourth embodiment of the vehicle battery management system based on satellite communication provided by this application. Figure 6 As shown, the vehicle battery management system based on satellite communication is used for:

[0093] S601: Receive unlocking information sent by the cloud platform, where the unlocking information is used to indicate that the user has paid for the paid power range of the single battery in the vehicle battery assembly.

[0094] S602: Send unlock information to the vehicle.

[0095] In this application, if the remaining power of a single battery reaches the preset paid power range, the use of the single battery is locked and a paid power usage confirmation message is pushed. After receiving the paid power usage confirmation message, the user needs to choose whether to pay the fee according to actual needs.

[0096] When the user completes the payment operation, the relevant payment system will generate payment confirmation information and send the information to the cloud platform through the network. The payment confirmation information is used to indicate whether the user has paid the fee for the paid power interval of the single battery. After receiving the payment confirmation information, the cloud platform will parse and verify it to confirm the user's payment status. Once it is confirmed that the user has completed the payment, the cloud platform will generate unlocking information accordingly, update the user's battery usage rights, and unlock the single battery, allowing the user to continue to use the power. Throughout the process, the payment confirmation information can timely convey the user's payment status and help the cloud platform determine whether to unlock the single battery.

[0097] After the vehicle's battery management unit receives the unlocking information sent by the cloud platform, when the unlocking information indicates that the user has paid for the paid power range of the single battery, it means that the user has completed the corresponding payment and meets the conditions for continuing to use the single battery. Therefore, the battery management unit will perform the unlocking process to allow the single battery to continue to discharge. The unlocking process includes updating the system status so that the use rights of the single battery are restored, so that the user can continue to freely use the power provided by the single battery without any restrictions.

[0098] The vehicle battery management system based on satellite communication provided in this embodiment receives unlocking information sent by the cloud platform, which is used to indicate that the user has paid the fee for the paid power interval of the single battery in the battery assembly, and sends the unlocking information to the vehicle. The system provides users with reliable services, ensuring that users can continue to use power smoothly after completing payment, while also ensuring the safety and stable operation of the vehicle.

[0099] Optionally, based on the fourth embodiment, the vehicle battery management system based on satellite communication can also be used for:

[0100] S603: Obtain consistency information sent by the vehicle, and send the consistency information to the cloud platform;

[0101] S604: Receive the battery management information returned by the cloud platform, and send the battery management information to the vehicle.

[0102] The vehicle battery management system based on satellite communication provided in this embodiment, the target satellite obtains the consistency information sent by the vehicle based on the satellite communication terminal, and forwards the consistency information to the cloud platform. The cloud platform receives the consistency information sent by the target satellite, generates battery management information based on the consistency information, and returns the battery management information to the target satellite. The target satellite receives the battery management information and forwards the battery management information to the vehicle, so that the vehicle can perform safe management of battery components based on the battery management information. In this way, data relay transmission between the vehicle and the cloud platform based on the target satellite can improve the reliability of data transmission, and the scene adaptability is also more extensive. It can be applied to various geographical scenarios and can ensure the real-time safety management of vehicle batteries.

[0104] S701: after determining that the user has paid for the use of the paid power interval of the single battery in the vehicle battery assembly, generating unlocking information, the unlocking information is used to indicate that the user has paid for the use of the paid power interval of the single battery;

[0105] S702: Send unlocking information to the vehicle via satellite communication.

[0106] In this application, after determining that the user has paid for the usage fee of the paid power interval of the single battery in the vehicle battery assembly, the cloud platform generates unlocking information, which is used to indicate that the user has paid for the usage fee of the paid power interval of the single battery, and can control the vehicle to unlock the single battery in the locked state. Afterwards, the cloud platform can send the unlocking information to the vehicle through satellite communication, so that the vehicle can unlock the single battery in the paid power interval, so that the single battery can continue to discharge, meet the user's power usage needs, and also ensure the safe and stable operation of the vehicle.

[0107] Figure 8 This is a flow chart of the sixth embodiment of the vehicle battery management system based on satellite communication provided by this application. Figure 8 As shown, the vehicle battery management system based on satellite communication is used for:

[0108] S801: Obtaining single cell battery consistency information sent by the vehicle based on satellite communication.

[0111] S804: Generate battery management information corresponding to the battery assembly based on the real-time status of each single battery and the target management operation.

[0112] In the present application, the cloud platform obtains the consistency information sent by the vehicle based on satellite communication, and can determine the real-time status of each single battery based on the consistency information. The real-time status can specifically be a fault state (i.e., an abnormal state) or a normal state, etc. For example, if the voltage of a single battery is lower than the normal range, the capacity decreases, or the temperature rises abnormally, the cloud platform can determine that the single battery is in a fault state. Afterwards, the cloud platform can determine the target management operation corresponding to the battery assembly based on the real-time status of each single battery. The target management operation can be a safety management measure performed on a single battery in a fault state, such as stopping charging the battery, limiting its discharge rate, or reminding maintenance personnel to replace the battery in time. Of course, the real-time status of a single battery can also be other types, corresponding to other target management operations, which is not limited in the present application.

[0113] After determining the real-time status of the single battery and the target management operation of the battery assembly, the cloud platform can generate the battery management information of the vehicle based on the real-time status and the target management operation. In this way, the cloud platform can quickly identify the single battery in the faulty or abnormal state based on the consistency information, and can determine the corresponding safety management measures to ensure the overall stability and safety of the battery assembly.
