The method may be performed by a charging device in the vehicle, which may be implemented in the form of hardware and/or software, and the device may generally be integrated in the car. As shown in Figure 2, the method includes the following steps.

S101. When receiving a remote charging command, obtain the charging mode carried in the remote charging command.

In the embodiment of this application, Figure 3 is the architecture and interface design diagram of the remote charging control system used in Embodiment 1 of this application, which mainly includes mobile terminal equipment, telematics system, vehicle controller, body control system, and battery management system. , charging system, air conditioning system, electronic stability system and transmission controller. The remote charging command is conveyed to the vehicle by pre-establishing a connection between each vehicle and the mobile terminal device. An application can be installed on the mobile terminal device, and the connection between each vehicle and the mobile terminal device can be established through the application. Connect, you can register the specified information of the vehicle on the application, For example, it can be the license plate number. When the vehicle registration information is completed on the application, a matching connection relationship is established between the mobile terminal device and the vehicle. When the vehicle is in a state where high-voltage power can be achieved, the vehicle can receive signals from The command information of the mobile terminal device enables the vehicle to realize the charging control function. The mobile terminal device can be a mobile phone, a tablet computer or a smart watch, or it can be a terminal device with data transmission function. Charging mode is a variety of modes preset on the application for users to choose. It can be a specific charging method, a combination of multiple charging methods, or switching between different modes. Select different charging modes and the vehicle will perform corresponding functions. It can be charging at a designated time, charging in real time, or charging at intervals.

The user downloads the designated application on the mobile terminal device, logs in to the program through the account and password, registers the user's relevant information, and enters the relevant information that the user can drive the target vehicle. At this time, the relationship between the user and the vehicle has already been established. A one-to-one connection relationship is established, and the user selects and determines the charging function that the vehicle currently needs to perform by operating the preset mode in the interface on the application. The execution process is the user's operation mode in the mobile terminal device interface, and the mode selection signal is transmitted to the T-Box. The T-Box converts the user's operation information into the user's remote charging instructions, and sends the remote charging instructions to the vehicle body. control system and vehicle controller. At this time, the vehicle controller receives the charging mode carried in the remote charging command.

For example, the user logs in to a designated account on the application on the mobile terminal device and sets a unique password. After entering the program page, the user registers vehicle-related information, which can be the vehicle plate number of a designated vehicle. The user selects to reserve charging on the application interface. mode, at this time the vehicle controller receives the task content of charging the target vehicle.

Optionally, the following describes how to obtain the charging mode carried in the remote charging command, including:

Generate remote charging instructions based on the charging information edited in the application; where the charging information includes the charging mode and the charging time corresponding to the charging mode;

Send the remote charging command to the target vehicle so that the target vehicle charges based on the charging mode.

In this embodiment, the user can select preset charging selection settings through the application program on the mobile terminal, configure all charging modes in the application program in advance, and display multiple different charging modes on the user interface. User selection, the user can complete the selection step by step through the prompts in the application. When the user selects an option for charging, the charging instruction can be generated. The charging instruction may also include a scheduled charging time. For example, the user selects the scheduled charging mode on the application interface and selects the charging time as three o'clock in the afternoon. At this time, the vehicle controller receives the task content of charging the target vehicle at three o'clock in the afternoon. When the time reaches the afternoon Three points perform charging functions for the target vehicle.

S102. Based on the charging mode, determine the current status information of the target vehicle.

The target vehicle is a vehicle that has established a communication connection with the mobile terminal device and needs to be charged. For example, the user pre-registers the vehicle's frame number and other related information on the application of the mobile terminal device. When he wants to remotely enable the reservation charging control, the user enters the operation interface of the application, and the selected registered vehicle is the target vehicle. . The current parameter information is the information about the body and vehicle status, which can be the status information of the hardware device of the target vehicle, or the status information of the communication connection of the target vehicle.

When the user issues an instruction to remotely enable scheduled charging control via a mobile terminal, the remote information control system integrated in the target vehicle receives and reads the instruction to enable scheduled charging control, and begins to determine whether a communication connection has been established with the user's mobile terminal device. Information about the vehicle's current body and vehicle status.

For example, if user A wants to turn on the scheduled charging function of the target vehicle at three o'clock in the afternoon, he will select the scheduled charging mode through the mobile terminal device, and then set the scheduled charging time. The application will package the user's mode selection and time and send it to the vehicle. in the T-Box and transmitted to the vehicle controller integrated in the target vehicle. After receiving and reading the instruction to turn on the scheduled charging control, the vehicle controller begins to detect the vehicle's current body and vehicle status information, such as charging Whether the gun is connected, whether the communication connection of the target vehicle is normal, etc.; if user A wants to charge the target vehicle immediately, he can turn on the real-time charging function of the target vehicle, select the real-time charging mode through the mobile terminal device, and the application will change the user's mode The selection is sent to the T-Box of the vehicle and transmitted to the vehicle controller integrated in the target vehicle. After receiving and reading the instruction to enable real-time charging control, the vehicle controller begins to detect the current body and vehicle status of the vehicle. Information; if the user has selected a charging mode, but temporarily needs to change the currently selected charging mode, the charging mode can be switched. Then select the mode you want to switch through the mobile terminal device, and the application sends the mode selected by the user to the T-Box of the vehicle. After receiving and reading the instruction to switch the charging mode, the vehicle controller begins to detect the current body of the vehicle. and vehicle status information.

S103. If the current status information meets the corresponding preset conditions, charge the target vehicle based on the charging mode.

The preset condition is a condition that is preset to a certain content in the vehicle control system. The preset condition can be one or a combination of multiple preset conditions. When the vehicle controller receives the remote charging control command, The vehicle control system compares the parameters set to determine the content with the current status information to determine whether the current status information meets the preset conditions. When a preset condition is set, if the current status information meets the set condition, the remote charging control function of the target vehicle is activated; if the current status information does not meet the set condition, the remote charging of the target vehicle cannot be started. control function. When the preset condition is a combination of multiple conditions, if all current status information meets the set conditions, the remote charging control function of the target vehicle is started; if any current status information does not meet the preset conditions, it cannot be started. Remote charging control function of the target vehicle. The charging function of the target vehicle is completed through the charging system in Figure 3. The target vehicle is connected to the power supply in the environment through the charging gun to charge the target vehicle. The power source can be charged using a household 220-volt power supply, a public charging pile, or you can apply for a charging pile to be built in your own parking space.

When the vehicle controller of the target vehicle receives the remote charging control command sent by the user, it starts the function of matching the current status information of the target vehicle with the preset conditions. If any current status information does not meet the preset conditions, it cannot Start the remote charging control function of the target vehicle and wait for the next instruction signal; if all current status information meets the preset conditions, start the remote charging control function of the target vehicle and execute the charging function according to the charging mode selected by the user.

For example, the target vehicle is well connected to the public charging pile in the parking lot. The user selects the scheduled charging mode through the mobile terminal device to make an appointment to charge the target vehicle at 3 p.m., and the vehicle controller receives and reads the information to enable the scheduled charging control. After the instruction, it starts to detect the current vehicle body and vehicle status information, and compares the current vehicle status information with the preset conditions to determine whether the current vehicle status information meets the preset conditions. If all current status information meets the preset conditions If the conditions are met, the remote charging control function of the target vehicle is activated. When the timer of the vehicle controller shows that it has reached three o'clock in the afternoon, the power in the public charging pile is input to the target vehicle.

With the above technical solution, users can choose multiple charging modes to achieve charging control of the target vehicle.

When a remote charging instruction is received, the charging mode carried in the remote charging instruction is obtained; based on the charging mode, the current status information of the target vehicle is determined; if the current status information meets the corresponding preset conditions, based on The charging mode charges the target vehicle. This application solves the problem of adaptive remote charging control on the premise of ensuring the safety of the vehicle and people, so as to charge the vehicle based on the charging mode, thereby improving the vehicle driving experience and enhancing the convenience of vehicle use.

Embodiment 2

Figure 4 is a flow chart of a vehicle charging method provided in Embodiment 2 of the present application. Based on the above-mentioned embodiment, the embodiment of the present application explains the content corresponding to the aforementioned embodiment S102 and S103. The embodiment of the present application can be compared with the above-mentioned embodiment. Multiple options are combined in one or more embodiments. As shown in Figure 4, the method includes the following steps.

S201. When receiving a remote charging command, obtain the charging mode carried in the remote charging command.

S202. Based on the charging mode, determine the current status information of the target vehicle.

Optionally, based on the above technical solution, the charging mode includes at least one of an immediate charging mode, a scheduled charging mode and a charging switching mode.

In this embodiment, the charging modes are diversified for the user to choose, mainly including instant charging mode, scheduled charging mode and charging switching mode. Instant charging mode is when the user wants to charge the target vehicle immediately In the case of charging, under the premise that the target vehicle and the charging pile have been connected, the user operates the application on the mobile terminal device and immediately charges the target vehicle. This mode is generally suitable for the target vehicle that still has some remaining power and the user temporarily needs it. When using a car, in order to ensure that the target vehicle has sufficient power, it is necessary to immediately store electricity for the target vehicle. The scheduled charging mode refers to charging the target vehicle according to the time specified by the user. With the popularity of new energy vehicles, more and more users are choosing new energy vehicles. As a means of transportation, vehicles are usually used for commuting. In this case, there will be peak charging periods for the vehicles, and the electricity price will be different throughout the day. The electricity price is higher during peak charging periods and lower during off-peak periods. Therefore, choosing a time period with lower electricity prices to charge the target vehicle can reasonably allocate resources and reduce charging costs. The charging switching mode is when the user has selected a charging mode, but temporarily needs to change the currently selected charging mode, the charging mode can be switched. Charging mode switching can include:

(1) Convert scheduled charging mode to real-time charging mode

1) When the vehicle is already in the charging process of scheduled charging mode, if the user operates the application to switch to real-time charging mode, all scheduled settings should be canceled for the vehicle, and then the vehicle will continue to charge;

2) When the vehicle is in scheduled charging mode but the scheduled start time has not been reached, if the user operates the application to switch to real-time charging mode, the target vehicle will enter the remote real-time charging control process;

(2) Convert real-time charging mode to scheduled charging mode

When the vehicle is charging in real time, the user operates the application to switch to the scheduled charging mode. When the set appointment time arrives, the T-Box sends a mode switching instruction to the vehicle controller. At this time, the target vehicle is in the scheduled charging mode.

(3) Modify the reserved charging time of the vehicle

The vehicle is in scheduled charging mode, and the driver can modify the scheduled charging time. If the scheduled charging start time is not reached, the T-Box can temporarily not send instructions to the relevant controller.

Based on the charging mode, determine the current status information of the target vehicle, including: if the charging mode is instant charging mode, the current status information of the target vehicle is obtained when the charging instruction is received; if the charging mode is the scheduled charging mode, the current status information of the target vehicle is obtained when the charging instruction is received; When commanding, the current status information of the target vehicle is obtained according to the charging time in the reserved charging mode; if the charging mode is the charging switching mode, when the charging instruction is received, the target vehicle is obtained according to the instant charging mode or the scheduled charging mode switched to current status information.

In this embodiment, after the user sends a remote charging control instruction through an application on the mobile terminal device and selects a charging mode, the instruction is transmitted to the vehicle's telematics system, and the telematics system transmits the user's instruction information Convert to user remote commands, and send the user remote commands to the vehicle controller respectively. When receiving the charging control command, the vehicle controller needs to determine the current status information of the target vehicle. The current status information of the target vehicle can reflect the status of the target vehicle. Is the status satisfied? conditions for charging to ensure the stability and safety of the target vehicle system during the charging control process.

S203. If the current status information meets the corresponding preset conditions, charge the target vehicle based on the charging mode.

Next, the current status information and preset conditions are introduced. The current status information includes at least one of the following: communication status between the AC charging gun and the target vehicle; key status; charger status; charger temperature information; battery status; Correspondingly, the preset conditions include: the communication status is normal communication; the key status is not connected; the temperature information is within the normal temperature range; and the battery is in a fault-free state.

In this embodiment, the communication status between the AC charging gun and the target vehicle refers to the connection transition state between the power source and the target vehicle. This signal is provided by the charging system in Figure 3. Charging can only be achieved when the charging gun and the power source are well connected. Function, the complete connection between the charging gun and the power source is the basic condition for all subsequent control content. The key status can determine whether the vehicle is in a drivable state. When the vehicle key status is Key Off or Key ACC, Key Off means that the vehicle power supply is not powered. At this time, the vehicle controller area network (Controller Area Network, CAN) is generally in a dormant state. ;Key ACC represents the power-on status of the vehicle. When the vehicle is powered on, the CAN network will wake up and start transmitting signals, but the engine has not started. The vehicle is basically connected to the 12V power supply voltage. At this time, the windows are available and the air conditioner can be turned on. .

In this embodiment, Figure 5 is a network topology diagram of the vehicle remote charging control system used in Embodiment 2 of the present application. The relevant CAN is described as follows: (1) Electric Vehicle CAN (EVCAN) mainly includes new energy-related Network nodes VCU, BMS, CCU, MCU; (2) Power Network (Power Train CAN, PTCAN) mainly includes traditional vehicle-related network nodes TCU and ESP, etc.; (3) Body Network (BodyCAN) mainly includes network nodes BCM, HVAC, etc.; (4) Different controller signal interactions across network nodes can be realized through the gateway GW node.

According to the network topology in Figure 5, the communication status of multiple communication nodes is checked through multiple controllers. The status information of the power system is mainly to check whether there is a fault in the power system, that is, whether the high-voltage power-on function of the motor and battery can be used normally. The current battery charge value and temperature information are provided by the battery management system shown in Figure 3 to ensure that there is no fault in the battery of the target vehicle.

S204. When the target vehicle is in the charging mode and receives the target function opening instruction, feedback information that the target function cannot be opened normally is fed back.

The target function is a function configured on the target vehicle other than charging control. For example, it may be the function of remotely turning on the air conditioner. For electric vehicles, there is only one power battery as the energy source, and whether the vehicle can drive is directly related to the energy of the battery. Therefore, the priority of the vehicle's remote charging function is set higher than the priority of the non-remote charging control function, for example, remotely turning on the air conditioning function. At this time, the user needs to be prompted through the application on the user interface that the target vehicle is currently in charging control mode and cannot respond.

For example, when the vehicle is in the process of turning on the remote air conditioner, the user operates the application on the mobile terminal device to switch to remote charging. At this time, the T-Box sends relevant instructions to the vehicle controller, and the vehicle controller should control the remote charging. The air conditioner is turned off and responds to the user's signal request for remote real-time charging or scheduled charging. When the vehicle is in the process of remote charging, the vehicle controller should send the battery status signal to the T-Box that it is charging, and the T-Box will inform the user through the application that the vehicle is in the process of charging. At this time, if the driver If the air conditioner is turned on remotely through operation control, the application will prompt the user that the vehicle is in the charging process and does not allow the air conditioner to be turned on. That is, during the vehicle charging process, it does not respond to the driver's signal request to remotely turn on the air conditioner.

The above technical solution proposes a vehicle power battery remote charging control method. By designing the remote control system architecture and functional interfaces, network topology, as well as remote air conditioning control strategies and remote battery charging control strategies, users can use their mobile devices to It can easily realize remote control of vehicles, meet users' diverse needs for target vehicle charging control, save charging costs, ensure reliable and stable operation of the charging system, ensure safe and reliable operation, and enrich the user experience with remote charging functions. The interaction between vehicles meets the diverse needs of users for target vehicle charging control, saves charging costs, ensures reliable and stable operation of the charging system, ensures safe and reliable operation of remote charging functions, and improves vehicle driving control experience, enhancing the convenience of using the vehicle.

Embodiment 3

In the embodiment of this application, the process of vehicle remote charging control is introduced in an implementation manner, which mainly includes the vehicle remote scheduled charging entry control strategy, the vehicle remote real-time charging entry control strategy, the vehicle remote real-time charging and scheduled charging mode conversion control strategy and the vehicle Remote charging exit control strategy.

1. Vehicle remote real-time charging access control strategy

The user can perform remote real-time charging control by operating the application on the mobile terminal device. The implementation process is as follows: the user operates the real-time charging mode of the application on the mobile terminal device, and the signal is transmitted to the vehicle-mounted T-Box as a remote charging command, and then the VCU The remote charging mode request sent by the T-Box is received in the real-time charging mode, that is, the signal Remote_CMReq=InsCharge mode; when the VCU determines that the following conditions are all met, the vehicle is controlled to enter remote charging. These conditions include: VCU receives the real-time charging request signal sent by T-Box and is set, that is, the signal InstantChargeReq=True, VCU detects that the vehicle key status is Key Off or Key ACC, VCU detects that the vehicle's battery charging gun is connected normally, and VCU detects the high-voltage system There is no fault, the battery does not report an insulation fault, the charger has no fault, the vehicle's high-voltage interlock is normal and the motor's active discharge circuit is normal. When the above conditions are met, the high-voltage system is considered to be fault-free; in addition, it is also necessary to determine whether the VCU receives the battery sent by the BMS. The charging status signal is the allowed charging mode. The VCU detects that the temperatures reported by the charger's temperature sensor 1 and temperature sensor 2 do not exceed the specified value (such as 65 degrees Celsius). When the VCU determines that all the above conditions are met, it controls the vehicle to perform remote charging. During the remote charging process, the BMS needs to send the battery charging status signal as charging. After the instrument receives the signal, Light up the battery charging status indicator on the instrument panel. After receiving the signal, the BCM controls the indicator light at the charging port to light up (for example, by flashing at a certain frequency).

2. Vehicle remote reservation charging access control strategy

Figure 6 is a process flow chart of the vehicle remote scheduled charging entry control strategy provided in Embodiment 3 of the present application, which includes the following steps: the user operates the scheduled charging mode of the application on the mobile terminal device and sets the scheduled charging time; the vehicle-mounted T-Box receives The timing starts after the scheduled charging mode instruction is reached; then T-Box determines whether the scheduled charging time is reached; when the scheduled charging time is reached, T-Box sends the charging mode carried in the remote charging command to the VCU, such as the scheduled charging mode signal Remote_CMReq =ResCharge mode and set signal ReserveChargeReq=True; after VCU determines that the reservation charging conditions are met based on the current status information of the target vehicle, it controls the vehicle to enter the reservation charging mode and controls vehicle charging; during the process of VCU controlling vehicle charging, if charging If an interruption occurs and is not resumed, after the specified time, the vehicle's controller enters sleep and the vehicle ends remote charging; during the process of VCU controlling vehicle charging, if charging is interrupted and then resumed, the T-Box will resume charging. Send the set signal ReserveChargeReq=True to the VCU, and the VCU continues to control the vehicle charging; finally, after the power battery is fully charged, the vehicle ends remote charging.

3. Vehicle remote real-time charging and scheduled charging mode conversion control strategy

The content of charging mode switching mainly includes three switching methods: converting the scheduled charging mode to real-time charging mode, converting the real-time charging mode to scheduled charging mode and modifying the vehicle's scheduled charging time. The conversion of scheduled charging mode to real-time charging mode also includes two situations: when the vehicle is already in scheduled charging mode and the charging mode is switched during the charging process; and when the vehicle is in scheduled charging mode but the scheduled start time has not been reached.

If the scheduled charging mode is selected to switch to the real-time charging mode, when the vehicle is already in the charging process of the scheduled charging mode, if the driver operates the application to switch to the real-time charging mode, all scheduled settings should be canceled for the vehicle. At this time, the T-Box Send Remote_CMReq=InsCharge mode and InstantChargeReq=True to the VCU, and then the vehicle continues to charge; when the vehicle is in the scheduled charging mode, but the scheduled start time has not been reached, if the driver operates the application to switch to real-time charging mode, the T-Box Send Remote_CMReq=InsCharge mode and InstantChargeReq=True to VCU to enter the remote real-time charging control process; if the real-time charging mode is selected to switch to the scheduled charging mode, when the vehicle is charging in real-time, the driver's operating application switches to the scheduled charging mode. When the set reservation time arrives, T-Box sends Remote_CMReq=ResCharge mode and ReserveChargeReq=True to VCU. Before the set reservation time arrives, T-Box sends VCU Remote_CMReq=ResCharge mode and ReserveCharge Req=False. If you choose to modify the vehicle's scheduled charging time, when the vehicle is in Key Off or Key ACC and the vehicle is in scheduled charging mode, the driver can modify the scheduled charging time. If the scheduled charging start time has not been reached, the T-Box can temporarily not charge the vehicle. The relevant controller sends instructions.

Exemplarily, FIG. 7 is a process flow chart of the vehicle remote scheduled charging and real-time charging mode conversion control strategy provided in Embodiment 3 of the present application. The implementation process is: the user operates the scheduled charging mode of the application of the mobile terminal device and sets the scheduled charging. The time is sent to the vehicle-mounted T-Box as a remote charging command. The vehicle-mounted T-Box starts timing after receiving the scheduled charging mode. Then the vehicle controller continuously determines whether the scheduled charging time has been reached. During this period, the user can switch the charging mode through the application. If the user does not click the mode switching button when the preset time is reached, the scheduled charging control mode will continue to be executed. If the user clicks the mode switching button within the preset time, the real-time charging control mode will be executed.

4. Vehicle remote charging exit control strategy

When the user wants to stop the charging control of the vehicle, the user can control the remote charging to stop by operating the application on the terminal device, and the vehicle exits the remote charging process. When the vehicle is in the process of remote charging startup or after remote charging startup is completed, if any of the following conditions is met, the vehicle should exit the remote charging process. These conditions include: VCU receives the remote charging mode request sent by T-Box to stop charging mode, that is, the signal Remote_CMReq = StpCharge mode, VCU detects that the hard wire signal connected to the charging gun is disconnected, the charger fails, and the vehicle high-voltage interlock is abnormal. , the battery reports an insulation fault, the battery reports that the battery is full, the VCU receives the battery charging request signal sent by the BMS to stop charging mode, and the VCU detects that the temperature sensor 1 or temperature sensor 2 of the charger reports that the temperature exceeds the specified value (such as 65 degrees Celsius). After the vehicle exits remote charging, the BMS sends a battery charging status signal to stop charging.
