[0010] Further, when the external vehicle requesting charging and this vehicle reach an agreement on the external charging protocol, obtain the real-time motion state of the external vehicle so that the charging interface of this vehicle is docked with the charging interface of the external vehicle, specifically including: After reaching an agreement on the external charging protocol, start the sensing system of this vehicle to obtain the real-time motion state of the external vehicle; Based on the real-time motion state of the external vehicle, adjust the driving state of this vehicle so that this vehicle and the external vehicle are on the same horizontal line and have the same driving state, and dock the charging port of this vehicle with the charging port of the external vehicle to charge the external vehicle.

[0011] In a second aspect, a charging system based on new energy vehicles in motion is provided, including: A receiving module for receiving the charging request signal from an external vehicle; A verification module, configured to verify whether the battery management system of an external vehicle is consistent with that of the vehicle itself; A construction module, configured to construct a charging protocol for the vehicle to charge external devices; An acquisition module, configured to acquire the real-time motion state of the external vehicle; A docking module, configured to dock the charging interface of the vehicle with the charging interface of the external vehicle.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. Traditional new energy vehicles mainly rely on fixed charging piles for charging. During long-distance travel or in remote areas, the distribution density of charging piles is limited, and vehicles often face the dilemma of not being able to find a suitable charging pile, resulting in insufficient power and inability to continue driving. However, this technical solution realizes charging between new energy vehicles in motion. Vehicles do not need to rely on fixed charging piles and can charge as long as they encounter vehicles with consistent battery management systems, greatly increasing the flexibility and convenience of charging and effectively alleviating the problem of range anxiety.

[0016] 2. The BMS consistency verification is carried out before the start of charging, which can detect in advance the mismatch between the two vehicles in terms of the battery management system and take timely measures to avoid potential risks.

[0017] 3. Mismatched battery parameters may impact the vehicle's electrical system. By comparing the battery parameters, the compatibility of the charging process with the vehicle's electrical system can be ensured, avoiding electrical system failures caused by charging and protecting the overall performance and safety of the vehicle.

[0018] 4. The Vehicle Identification Number (VIN) is the unique identity identifier for each vehicle.

[0019] 5. Re-checking whether the battery management system of the external vehicle is consistent with that of this vehicle is an important supplement and confirmation to the previous checking process. In a complex communication environment and in the presence of possible interference, the secondary check can avoid problems of BMS inconsistency caused by signal misjudgment or data transmission errors.

[0020] 6. Based on the real-time motion state of the external vehicle, adjust the driving state of this vehicle so that this vehicle and the external vehicle are on the same horizontal line and have the same driving state.

[0029] With the global emphasis on environmental protection and energy sustainable development, new energy vehicles have been widely promoted and applied. However, the problem of range anxiety of new energy vehicles has always been a key factor restricting their further development. At present, new energy vehicles mainly rely on fixed charging piles for charging. The distribution density of these charging piles is limited and the charging time is long. During long-distance driving or in remote areas, new energy vehicles often have difficulty finding a suitable charging pile, resulting in the vehicle being unable to continue driving due to insufficient power, which brings great inconvenience to users.

[0030] In addition, the existing charging methods are mainly carried out when the vehicle is stationary, which not only limits the usage scenarios of new energy vehicles but also reduces the operation efficiency of the vehicles. For example, in the fields of logistics distribution and public transportation, vehicles need to frequently stop at charging stations for charging, increasing the operation cost and time cost. Moreover, large-scale construction of charging piles requires a large amount of land, funds and resource investment, and the construction period is long, making it difficult to meet the rapidly growing charging demand of new energy vehicles.

[0031] To solve the above technical defects, the inventor provides a charging method, system and device based on new energy vehicles in motion.

[0032] The following further describes the present invention in detail with reference to the accompanying drawings: In a first aspect, an embodiment of the present invention provides a charging method based on new energy vehicles in motion, as Figure 1 shown, including: S101. While receiving a charging signal request from an external vehicle, check whether the battery management system of the external vehicle is consistent with that of the present vehicle; Exemplarily, first, while receiving a charging signal request from an external vehicle, send a BMS information communication link to the external vehicle to obtain the BMS information of the external vehicle, read the BMS information of the present vehicle, and compare it with the received BMS information of the external vehicle; wherein, if the external vehicle is consistent with the BMS of the present vehicle, the judgment result is transmitted to the control systems of the present vehicle and the external vehicle; if the external vehicle is inconsistent with the BMS of the present vehicle, the present vehicle sends a rejection signal to the external vehicle and explains the reason for rejection.

[0033] In the above steps, by sending a BMS information communication link to the external vehicle to obtain its BMS information and comparing it with the BMS information of the present vehicle, it is possible to accurately judge whether the battery management systems of both parties are consistent. Different BMSs may have differences in communication protocols, charging control strategies, battery parameter management, etc. Only by ensuring the consistency of the BMSs of both parties can the accurate transmission of data and the safe execution of charging operations be guaranteed during the charging process, avoiding charging failures, battery damage, and even safety accidents caused by BMS incompatibility. Secondly, checking the BMS consistency before the start of charging can detect the mismatch of the battery management systems of both vehicles in advance, and take timely measures to avoid potential risks. If the BMSs are inconsistent, the present vehicle sends a rejection signal to the external vehicle and explains the reason for rejection, preventing various problems that may be caused by forced charging and ensuring the safety and reliability of the charging process.

[0034] Furthermore, checking the BMS consistency while receiving a charging signal request from an external vehicle can quickly screen out vehicles with the same BMS as the present vehicle, avoiding unnecessary charging negotiation and preparation processes. For vehicles with inconsistent BMSs, the charging request is rejected in a timely manner, saving the time and resources of both parties and improving the charging efficiency. Only when the BMSs of both parties are consistent will the judgment result be transmitted to the control systems of the present vehicle and the external vehicle, and enter subsequent processes such as charging protocol construction and charging interface docking, which ensures that the charging process is carried out on the basis of system compatibility between both parties, reduces the possibility of charging interruption or failure caused by system incompatibility, and improves the charging success rate.

[0035] In addition, when the BMS of the external vehicle is inconsistent with that of the host vehicle, the host vehicle sends a rejection signal to the external vehicle and explains the reason for rejection. This clear feedback mechanism enables the users of the external vehicle to clearly understand the reason for the rejection of the charging request, avoiding confusion or dissatisfaction of the users due to unclear situations and enhancing the user experience.

[0036] Throughout the process, through operations such as sending BMS information communication links, obtaining and comparing BMS information, and feedback judgment results, effective information interaction between the host vehicle and the external vehicle is achieved. Both vehicles can timely understand the status of each other's battery management systems and the feasibility of charging, providing a basis for subsequent charging decisions, and improving the transparency and communication efficiency of the charging process.

[0037] Finally, through BMS consistency verification, it can be ensured that charging resources are only allocated to vehicles with consistent BMS, avoiding waste of charging resources caused by BMS incompatibility. Under the conditions of limited charging resources and time, the resources are preferentially allocated to rechargeable vehicles, improving the utilization efficiency of charging resources and making the charging process more reasonable and efficient. In the case of large-scale popularization of new energy vehicles, this technical solution helps to achieve the coordination and management of charging between vehicles. Through BMS consistency verification, rechargeable vehicle combinations can be quickly screened out, providing a basis for the scheduling and allocation of large-scale vehicle charging and contributing to the construction of a more efficient and orderly charging network.

[0038] Furthermore, reading the BMS information of the host vehicle and comparing it with the BMS information of the received external vehicle specifically includes comparing the battery types, rated voltages, rated currents, and charging cut-off voltages of the host vehicle and the external vehicle. Different types of batteries have different chemical characteristics and charging requirements. For example, there are significant differences in charging methods and charging rates between lithium-ion batteries and lead-acid batteries. If charging is carried out with mismatched battery types, it may lead to problems such as battery overheating, overcharging, and short circuits, seriously damaging the battery and even causing safety accidents such as fires and explosions. By comparing the battery types, it can be ensured that charging only occurs between batteries of the same or compatible types, avoiding safety risks caused by differences in battery characteristics.

[0039] The rated voltage, rated current, and charging cut-off voltage of a battery are key parameters during the battery charging process. The rated voltage determines the normal operating voltage range of the battery, the rated current reflects the maximum charging current that the battery can withstand, and the charging cut-off voltage is the upper limit of the battery voltage during charging. If these parameters do not match, it may cause the battery voltage to be too high and the current to be too large during charging, exceeding the battery's tolerance range and thus damaging the battery. Strictly comparing these parameters can ensure that the charging process operates within the safe operating range of the battery, effectively preventing battery damage. At the same time, mismatched battery parameters may impact the vehicle's electrical system. For example, an overly high charging voltage may damage the vehicle's charging equipment, battery management system, and other electronic components. By comparing the battery parameters, the compatibility of the charging process with the vehicle's electrical system can be ensured, avoiding electrical system failures caused by charging and protecting the overall performance and safety of the vehicle.

[0040] Moreover, understanding information such as the rated voltage, rated current, and charging cut-off voltage of both batteries helps in formulating more optimized charging strategies. For example, determining the appropriate charging current based on the battery's rated current can avoid the charging current being too large or too small. An overly large charging current may cause the battery to heat up severely, reducing the charging efficiency and even damaging the battery; an overly small charging current will prolong the charging time. By comparing the parameters, the most suitable charging current can be selected to improve the charging efficiency and shorten the charging time. For different types of batteries, the charging method can also be adjusted according to their characteristics. For example, lithium-ion batteries usually require a constant current - constant voltage charging method, while lead-acid batteries have different charging requirements. By comparing the battery type and related parameters, the most suitable charging method for both batteries can be adopted to improve the charging efficiency.

[0041] In addition, comparing battery parameters before charging can quickly determine whether the two batteries are suitable for charging. If the parameters do not match, the charging attempt can be terminated in a timely manner, avoiding the time and resources wasted due to mismatched charging operations. This can improve the charging success rate, reduce unnecessary charging attempts, and enhance the overall charging efficiency. In the charging scenario between new energy vehicles in motion, standardized parameter comparison makes it easier for different vehicles to conduct charging interactions. Vehicles do not need to perform complex adaptations and adjustments. As long as the parameters match, they can charge, improving the convenience and universality of charging between vehicles and facilitating the widespread application of in-motion charging technology.

[0042] Furthermore, while receiving the charging request signal from an external vehicle, a BMS information communication link is sent to the external vehicle to obtain the BMS information of the external vehicle. Specifically, it includes receiving the charging request signal sent by the external vehicle and parsing the received signal to extract the vehicle identification number of the external vehicle. The vehicle identification number (VIN) is the unique identity identifier of each vehicle. By parsing the charging request signal to extract the VIN of the external vehicle, the specific vehicle sending the charging request can be accurately identified, avoiding signal confusion and misjudgment that may occur in a multi-vehicle environment, and ensuring that this vehicle conducts subsequent charging information interaction and operations with the correct external vehicle. At the same time, accurately obtaining the VIN of the external vehicle is a prerequisite for establishing the BMS information communication link. Based on this VIN, this vehicle can specifically establish a safe and stable communication connection with the external vehicle to ensure the accurate transmission of data between the two parties. This provides a reliable communication foundation for subsequent operations such as obtaining the BMS information of the external vehicle and conducting charging negotiations.

[0043] During the charging communication process, only vehicles that have been correctly identified and verified can conduct information interaction with this vehicle. By extracting the VIN and conducting identity verification, illegal vehicles or malicious devices can be effectively prevented from accessing the charging system, ensuring the data security and privacy of the charging process, and avoiding security issues such as vehicle information leakage and charging system attacks caused by illegal access.

[0044] After extracting the VIN of the external vehicle, this vehicle can associate and record this information with the relevant data of the charging process, which helps to establish a complete charging management database, facilitating the query, statistics, and analysis of charging records. For example, information such as the charging times and charging amounts of different vehicles can be statistically analyzed, providing data support for the planning and management of charging facilities.

[0045] In the case where multiple external vehicles request charging, different vehicles can be clearly distinguished through the VIN, facilitating this vehicle to prioritize and coordinate the management of charging requests. According to factors such as the power demand and driving status of the vehicles, the charging order can be reasonably arranged to improve the utilization efficiency of charging resources and ensure the orderly progress of the charging process.

[0046] If a fault or abnormal situation occurs during the charging process, through the previously extracted VIN information, the relevant external vehicle can be quickly located, which helps to promptly investigate the cause of the fault and take corresponding solutions to reduce the impact of the fault on the charging process.

[0047] When problems with the battery or vehicle system are detected during charging, the VIN information can serve as an important basis for tracing the production, usage, and maintenance of the vehicle. By analyzing the charging records and fault information of relevant vehicles, it helps to improve the design and manufacturing processes of the vehicle and battery, enhancing product quality and safety. Different brands and models of vehicles may adopt different communication protocols and data formats, but as a universal identifier for vehicles, the VIN has broad compatibility. By extracting the VIN and establishing a communication link, this vehicle can interact with various types of external vehicles for charging information, improving the adaptability and expandability of the charging system.

[0048] S102. When the battery management systems of both sides are consistent, construct the external charging protocol of this vehicle and send it to the external requesting charging vehicle. Exemplarily, re-check whether the battery management system of the external vehicle is consistent with that of this vehicle. When they are consistent, analyze the charging capacity of this vehicle, determine the key parameters of the external charging protocol, then construct the protocol framework for the external charging of this vehicle, encode the charging protocol, encapsulate the charging protocol data packet, and send it to the external requesting charging vehicle. Re-checking whether the battery management system of the external vehicle is consistent with that of this vehicle is an important supplement and confirmation to the previous checking link. In a complex communication environment and possible interference, secondary checking can avoid problems of inconsistent BMS caused by signal misjudgment or data transmission errors. Only by ensuring that the BMS of both sides is truly consistent can the subsequent charging protocol construction link be entered, fundamentally ensuring the safety and compatibility of the charging process and preventing charging failures and safety accidents caused by BMS mismatches.

[0049] Analyzing the charging capacity of this vehicle is carried out on the premise that the BMS of both sides is consistent. It can accurately evaluate key indicators such as the charging power and electricity that this vehicle can provide in the current state, helping to avoid situations where the charging capacity of this vehicle is insufficient to meet the needs of the external vehicle or the battery of this vehicle is damaged due to overcharging. By precisely analyzing the charging capacity, it can provide a reliable basis for determining the key parameters of the external charging protocol, ensuring that the charging process is carried out within the safe tolerance range of this vehicle.

[0050] Determining the key parameters of the external charging protocol, such as charging voltage, current, charging time, etc., is the core of constructing an efficient charging protocol. These parameters are directly related to the speed, efficiency, and safety of charging. Reasonably determining the key parameters based on the BMS information of both sides and the charging capacity of this vehicle can make the charging process more accurate and efficient, avoid energy waste and unnecessary losses during charging, improve charging efficiency, and shorten the charging time.

[0051] Secondly, constructing the protocol framework for the vehicle's external charging provides a standardized specification and process for the charging process. The standardized protocol framework helps both vehicles clearly understand various operations and requirements during charging, reducing charging problems caused by poor communication or misunderstandings. At the same time, the standardized protocol also facilitates charging interactions between different vehicles, improving the universality and compatibility of the charging system.

[0052] In addition, encoding and encapsulating the charging protocol into a charging protocol data packet can ensure the integrity and accuracy of data during transmission. The encoding process can convert the charging protocol information into a format suitable for transmission, avoiding data loss, damage, or misinterpretation during transmission. Encapsulating the data packet can add necessary identification and verification information to the data, facilitating the receiving party to identify and verify the data, further improving the reliability of data transmission.

[0053] Sending the charging protocol data packet to the vehicle requesting external charging realizes the key information interaction between the two vehicles. A stable and accurate sending mechanism ensures that the external vehicle can receive the charging protocol information in a timely and complete manner, providing a necessary prerequisite for subsequent charging operations. It helps both vehicles prepare for and perform charging operations according to the protocol content, ensuring the smooth progress of the charging process. By constructing and sending the charging protocol, the vehicle requesting external charging can clearly understand the charging rules, processes, and key parameters. This gives users clear expectations during the charging process, improving the user experience. At the same time, it also helps reduce misoperations and disputes caused by users' lack of understanding of the charging process. The standardized charging protocol and data transmission mechanism facilitate charging management. The charging management system can monitor and manage the charging process in real time according to the protocol information, promptly detecting and handling problems that occur during charging. At the same time, charging records and data can also provide strong support for the planning, optimization, and fault troubleshooting of charging facilities, improving the level and efficiency of charging management.

[0054] S103. After reaching an agreement on the external charging protocol between the external vehicle requesting charging and this vehicle, obtain the real-time motion state of the external vehicle, so that the charging interface of this vehicle is docked with the charging interface of the external vehicle. Exemplarily, after reaching an agreement on the external charging protocol, start the sensing system of this vehicle to obtain the real-time motion state of the external vehicle. Based on the real-time motion state of the external vehicle, adjust the driving state of this vehicle so that this vehicle and the external vehicle are on the same horizontal line and have the same driving state, and dock the charging port of this vehicle with the charging port of the external vehicle to charge the external vehicle. During the above steps, starting the sensing system of this vehicle to obtain the real-time motion state of the external vehicle can accurately master key information such as the position, speed, acceleration, and driving direction of the external vehicle, thus laying the foundation for adjusting the driving state of the whole vehicle and realizing the docking of the charging interface. By obtaining it in real time, it can ensure that this vehicle is adjusted according to the actual motion of the external vehicle, avoiding docking failures caused by information lag or inaccuracy. Based on the real-time motion state of the external vehicle, adjust the driving state of this vehicle so that this vehicle and the external vehicle are on the same horizontal line and have the same driving state, which can minimize the relative motion between the two vehicles and reduce the difficulty of docking the charging interface. For example, when the external vehicle accelerates, this vehicle also accelerates accordingly; when the external vehicle turns, this vehicle adjusts the steering in a timely manner to ensure that the two vehicles remain relatively stationary or move synchronously, thereby improving the success rate of docking the charging interface.

[0055] During the process of obtaining the real-time motion state of the external vehicle and adjusting the driving state of this vehicle, this vehicle can understand the relative position and distance from the external vehicle in real time, avoiding collision accidents caused by the inconsistent motion of the two vehicles. Especially in high-speed driving or complex road conditions, this safety guarantee is particularly important, ensuring the safety of the vehicle and personnel during the charging process.

[0056] Since the two vehicles are in a relatively stationary or synchronous motion state when docking the charging interface, the impact and damage to the charging interface caused by excessive relative motion are reduced. This helps to extend the service life of the charging interface, reduce the maintenance cost of the charging facilities, and at the same time ensure the stability and reliability of the charging process.

[0057] By obtaining the external vehicle's motion state in real time and adjusting the driving state of the vehicle itself to achieve the docking of the charging interface, a large amount of practical operation experience has been accumulated. This experience is of great significance for further optimizing the charging algorithm and improving the intelligence level of the charging system. At the same time, it also provides a practical basis for the research and innovation of charging technologies, helping to promote the continuous development of charging technologies. During the process of achieving the docking of the charging interface, certain technical specifications and standards need to be followed. This kind of practice helps to form unified standards and operation procedures for charging interface docking, promoting the compatibility and interoperability between different vehicles and charging devices. The advancement of standardization will reduce the construction cost of charging facilities, improve the quality and efficiency of charging services, and promote the healthy development of the new energy vehicle industry.

[0058] In the second aspect, a charging system based on moving new energy vehicles is provided, as Figure 2 shown, including: A receiving module, used for receiving a charging request signal from an external vehicle; A verification module, used for verifying whether the battery management systems of the external vehicle and the vehicle itself are consistent; A construction module, used for constructing an external charging protocol for the vehicle itself; An acquisition module, used for acquiring the real-time motion state of the external vehicle; A docking module, used for docking the charging interface of the vehicle itself with the charging interface of the external vehicle.

[0059] During specific operations, the system also includes a battery management system (BMS), a DC - DC converter, a charging interface, and a control unit; the battery management system (BMS) is used for monitoring and managing the state of the vehicle battery, including parameters such as the battery's power, voltage, and temperature, and communicating with other systems of the vehicle.

[0060] In the discharging vehicle, the DC - DC converter converts the high-voltage direct current output by the battery into a voltage suitable for charging; in the receiving vehicle, the received electrical energy is appropriately converted and stored in its own battery.

[0061] The charging interface is set at a suitable position on the vehicle, used for connecting the discharging vehicle and the receiving vehicle to achieve the transmission of electrical energy.
