[0052] FIG1 is a flow chart of a charging method provided by an embodiment of the present invention. As shown in FIG1 , the method includes:

[0053] Step 101: The user equipment obtains a charging power limit.

[0054] In an embodiment of the present invention, a charging method is applied to a user device, including but not limited to a mobile phone, tablet computer, portable PC, desktop computer, wearable device, etc. The user device includes a vehicle charging application (APP), and a server that develops the vehicle charging application is in communication with the user device. After the user device runs the vehicle charging application, a charging settings interface may be displayed. The user may set a charging power limit through the user device according to the displayed charging settings interface. The charging power limit may be a battery power range or a specific value, for example, a charging power limit of 60%-80% or a charging power limit of 100%. The charging settings interface may include the user-set charging power limit, making it easier for the user to select the desired charging power level. The user device may display a default charging power limit. If the user does not change the default charging power limit, the charging power limit obtained by the user device is the default charging power limit, for example, a default charging power limit of 100%.

[0055] Step 102: The user device generates charging-related information based on the reservation type obtained from the user input and in response to the user input for setting other information.

[0056] In this embodiment of the present invention, the reservation type includes a single reservation type or a daily reservation type. When the reservation type includes a single reservation type, the charging-related information includes the scheduled charging start time; when the reservation type includes a daily reservation type, the charging-related information includes the scheduled charging start time and the scheduled charging end time.

[0057] Step 103: The user equipment generates reservation information according to the charging power limit, reservation type, and charging-related information.

[0058] In the embodiment of the present invention, the reservation information includes a charging power limit, a reservation type, and charging-related information.

[0059] Step 104: The user device sends the reservation information to the vehicle, so that the vehicle is charged according to the reservation information.

[0060] In an embodiment of the present invention, a user device is connected to a server, and a vehicle is also connected to the server. The user device sends reservation information to the server, and the server forwards the reservation information to the vehicle. The vehicle includes a communication module, and the communication module receives the reservation information.

[0061] An embodiment of the present invention provides a charging method, in which a user device obtains a charging power limit; based on the obtained reservation type input by the user, charging-related information is generated in response to the operation of setting other information input by the user; reservation information is generated according to the charging power limit, the reservation type and the charging-related information; the reservation information is sent to a vehicle so that the vehicle is charged according to the reservation information, so that the user can set the charging power limit, the reservation type and the charging-related information through the user device, which is convenient for the user to set the battery power at the end of charging, convenient for the user to reasonably choose whether to make a single reservation for charging according to his own needs, and also convenient for the user to choose the time to start charging, so that the vehicle can be charged according to the reservation information, and then the vehicle can determine the time to end charging according to the charging power limit or charging-related information, thereby improving the customer experience.

[0062] In one possible implementation, the reservation type includes a single reservation type, and the charging-related information includes a first scheduled charging start time; step 102 may specifically include: step 1021, the user device generates a first scheduled charging start time in response to an operation of setting other information input by the user based on the reservation type being a single reservation type.

[0063] In this embodiment of the present invention, a single-time scheduled charging type is a type that only executes the scheduled charging once. The first scheduled charging start time is the time point set by the user to start the scheduled charging. The charging setting interface also includes a scheduled charging button. The user can select the time point to start the scheduled charging by clicking the scheduled charging button on the user device.

[0064] The charging-related information also includes a first scheduled charging end time. Step 102 may specifically include: Step 1022: The user device determines the first scheduled charging end time based on the reservation type being a single reservation type. When the user confirms that the reservation type is a single reservation type, the user device determines that the first scheduled charging end time is not available.

[0065] In one possible implementation, the reservation type includes a daily reservation type, and the charging-related information includes a second scheduled charging start time and a second scheduled charging end time; step 102 may specifically include: step 1023, the user device obtains and displays a reference end time sent by the server based on the reservation type being a daily reservation type, the reference end time being a time generated by the server based on the acquired vehicle current information, charging power limit, and vehicle historical charging information; step 1024, the user device generates a second scheduled charging start time and a second scheduled charging end time based on the reference end time in response to an operation input by the user to set other information.

[0066] In an embodiment of the present invention, the daily appointment type is opposite to the single appointment type, and can be expressed as a type of executing the scheduled charging multiple times. The second scheduled charging start time is the time point set by the user to start the scheduled charging; the second scheduled charging end time is the time point set by the user to end the scheduled charging. After the user selects the daily appointment type, the user device will send an appointment type notification message to the server; in response to the appointment type notification message, the server generates a reference end time based on the acquired vehicle current information, charging power limit and vehicle historical charging information. The vehicle's current information includes the vehicle's third current battery power; the vehicle's historical charging information includes the vehicle's previous battery charging status, for example, the vehicle's historical charging information includes the changes in the battery power of the vehicle over a period of time. The reference end time is an estimated time required for the battery power to increase from the third current battery power to the charging power limit for the user's reference. The reference end time can be expressed by a time period or a time point. The embodiment of the present invention does not limit the representation method of the reference end time.

[0067] The user can select a second scheduled charging end time based on the displayed reference end time. After the user selects the second scheduled charging start time and the second scheduled charging end time, the user device displays a confirmation button. In response to the user clicking the confirmation button, the user device generates the second scheduled charging start time and the second scheduled charging end time.

[0068] In a possible implementation, step 104 further includes: step 105: the user device generates reservation cancellation information in response to the reservation cancellation operation input by the user; and sends the reservation cancellation information to the vehicle.

[0069] In an embodiment of the present invention, the user device may display a button for closing the scheduled charging schedule. In response to a user clicking the button, the user device generates a cancellation message. The user device transmits the cancellation message to a server, which forwards it to the vehicle's communication module. The communication module then controls the vehicle to enable charging upon connection to an off-board charger, thereby enabling the vehicle to cancel the scheduled charging schedule and enable charging upon connection to the off-board charger.

[0070] An embodiment of the present invention provides a charging method, in which a user device obtains a charging power limit; based on the obtained reservation type input by the user, charging-related information is generated in response to the operation of setting other information input by the user; reservation information is generated according to the charging power limit, the reservation type and the charging-related information; the reservation information is sent to a vehicle so that the vehicle is charged according to the reservation information, so that the user can set the charging power limit, the reservation type and the charging-related information through the user device, which is convenient for the user to set the battery power at the end of charging, convenient for the user to reasonably choose whether to make a single reservation for charging according to his own needs, and also convenient for the user to select the start time of charging or the start time and end time of charging, so that the vehicle can be charged according to the reservation information, and then the vehicle can determine the end time of charging according to the charging power limit or the charging-related information, thereby improving the customer experience.

[0071] FIG2 is a flow chart of another charging method provided by an embodiment of the present invention. The method is applied to a vehicle, and the vehicle includes a communication module and a controller module. As shown in FIG2 , the method includes:

[0072] Step 201: The communication module controls the controller module to charge the vehicle based on the reservation information received from the user device, where the reservation information is a charging power limit obtained by the user device; generates charging-related information based on the reservation type obtained from the user input and in response to the user input for setting other information; and generates information based on the charging power limit, the reservation type, and the charging-related information.

[0073] In the embodiment of the present invention, the communication module includes a telematics box (TBOX), and the controller module includes a vehicle control unit (VCU).

[0074] Figure 3 is a schematic diagram of an interaction provided by an embodiment of the present invention. As shown in Figure 3, Figure 3 illustrates the vehicle's remote communication module, charging and distribution module, vehicle controller, and battery management module, as well as a mobile phone, server, and off-board charger. The mobile phone and server can send remote commands to each other; the server and remote communication module can send remote commands to each other; the off-board charger can charge the battery management module. The remote communication module is connected to the charging and distribution module, vehicle controller, and battery management module via a gateway, and the vehicle controller is connected to the battery management module. As shown in Figure 3, the user device includes a mobile phone, which sends reservation information to the server, and the server forwards the reservation information to the remote communication module.

[0075] An embodiment of the present invention provides a charging method, in which a communication module controls a controller module based on reservation information received from a user device to enable a vehicle to charge, wherein the reservation information is for the user device to obtain a charging power limit; based on the reservation type obtained from the user input, charging-related information is generated in response to the user input for setting other information; information generated based on the charging power limit, the reservation type, and the charging-related information allows the vehicle to determine the start and end times of charging based on the reservation information, thereby controlling the vehicle charging time and improving the customer experience.

[0076] In one possible implementation, the reservation information includes a charging power limit, a reservation type, and charging-related information, wherein the reservation type includes a single reservation type, and the charging-related information includes a first scheduled charging start time. Step 201 may specifically include:

[0077] Step 2011 : The communication module determines whether to charge the vehicle based on the first current time and the first scheduled charging start time. If so, execute step 2012 ; if not, execute step 2016 .

[0078] In the embodiment of the present invention, the communication module determines whether the first current time reaches the first scheduled charging start time; if it is determined that the first current time reaches the first scheduled charging start time, it is determined that the vehicle is charged and step 2012 is executed; if it is determined that the first current time does not reach the first scheduled charging start time, it is determined that the vehicle is not charged and step 2016 is executed.

[0079] Figure 4 is an interactive flow chart provided by an embodiment of the present invention. As shown in Figure 4, a user logs into a mobile app and sets a charging power limit of 60%-80% on the charging interface of the mobile app. The default charging power limit is 100%. The mobile phone displays a reservation type selection interface, which includes single reservation type and daily reservation type. If the user selects the single reservation type, the mobile phone displays a reservation charging start time interface in response to the user's selection. The user can set the reservation charging start time. The mobile phone forwards a remote reservation charging instruction to the vehicle's TBOX via a server. The remote reservation charging instruction includes the charging power limit, single reservation type, and reservation charging start time. If the user selects the daily reservation type, the mobile phone displays a reservation charging start time and reservation charging end time interface in response to the user's selection. The reservation charging start time and reservation charging end time interface displays the estimated time required to charge from the vehicle's current power level to the charging power limit. The user can set the reservation charging start time and reservation charging end time. The mobile phone forwards the remote reservation charging instruction to the vehicle's TBOX via a server. The remote reservation charging instruction includes the charging power limit, daily reservation type, reservation charging start time, and reservation charging end time. TBOX stores the charging power limit and charging time, where the charging time includes the scheduled charging start time or the charging time includes the scheduled charging start time and the scheduled charging end time. TBOX determines whether the current time has reached the scheduled charging start time. If the TBOX determines that the current time has not reached the scheduled charging start time, and if the current vehicle network is in an awake state, the TBOX sends a "scheduled charging request = prohibited charging" + charging power limit signal to the VCU based on the current vehicle network, and the VCU controls the entire vehicle to prohibit charging. If the TBOX determines that the current time has reached the scheduled charging start time, it wakes up and maintains the vehicle network, and sends a "scheduled charging request = allowed charging" + charging power limit signal to the VCU based on the vehicle network. The VCU controls the entire vehicle to enter the charging process and charge at high voltage. The TBOX determines whether the reservation type is a single reservation. If so, the TBOX does not perform any operation and ends the subsequent process. At the same time, the VCU determines whether the battery level has reached the charging limit. If the VCU determines that the battery level has not reached the charging limit, it continues to determine whether the battery level has reached the charging limit until it determines that the battery level has reached the charging limit. At this point, the vehicle controls the charging process to end and the high voltage is released. The mobile app notifies the user that charging is complete.If the reservation type is daily, the TBOX determines whether the current time has reached the scheduled charging deadline, and the VCU determines whether the battery level has reached the charging limit and / or whether a "forbidden charging" request has been received. If the TBOX determines that the current time has not reached the scheduled charging deadline, it continues to perform the step of determining whether the current time has reached the scheduled charging deadline until the TBOX determines that the current time has reached the scheduled charging deadline, at which point it sends a scheduled charging request of "forbidden charging" to the VCU. If the VCU determines that the battery level has not reached the charging limit and has not received a "forbidden charging" request, it continues to determine whether the battery level has reached the charging limit and / or whether a "forbidden charging" request has been received. Until the VCU determines that the battery level has reached the charging limit and / or receives a "forbidden charging" request, it controls the vehicle to terminate the charging process and release the high voltage. The mobile app notifies the user that charging is complete.

[0080] Step 2012: Based on the vehicle network being in an awake state, the communication module sends a first scheduled charging request message to the controller module through the vehicle network. The first scheduled charging request message includes a charging power limit and a first scheduled charging request.

[0081] In this embodiment of the present invention, when it is determined that the vehicle is charging, if the vehicle network is not awake, the communication module will wake up and maintain the vehicle network. The vehicle network includes a Controller Area Network (CAN), which includes a CAN bus. The communication module actively sends a vehicle network management message to wake up the CAN network. As shown in Figure 3, the TBOX sends a first scheduled charging request message to the VCU through the vehicle network gateway. As shown in Figure 4, the first scheduled charging request is a "scheduled charging request = allow charging" request.

[0082] Step 2013: The controller module controls the vehicle to be in a charging state according to the first scheduled charging request.

[0083] In the embodiment of the present invention, the vehicle has been connected to the off-board charger, as shown in Figure 3, and the off-board charger is connected to the battery management module, as shown in Figure 4. The VCU controls the entire vehicle to enter the charging process, applies high voltage for charging, and enables the off-board charger to charge the vehicle.

[0084] Step 2014: The controller module determines whether to end charging the vehicle based on the charging power limit and the first current battery power. If so, execute step 2015; if not, execute step 2014.

[0085] In this embodiment of the present invention, prior to step 2014, the communication module determines that the reservation type is a single reservation type and that the vehicle is in a charging state. The controller module determines whether the first current battery power level has reached the charging power limit. If so, the controller module determines to terminate vehicle charging and executes step 2015. If not, the controller module determines to continue vehicle charging and executes step 2014.

[0086] Step 2015: The controller module controls the vehicle to be in a non-charging state.

[0087] In the embodiment of the present invention, as shown in FIG4 , the VCU controls the entire vehicle to end the charging process and lower the high voltage.

[0088] Step 2016: The communication module determines whether the vehicle network is in the awake state. If so, execute step 2017; if not, execute step 2011.

[0089] In the embodiment of the present invention, the vehicle network may be in an awake state or a non-awakened state.

[0090] Step 2017: The communication module sends a first charging prohibition message to the controller module through the vehicle network.

[0091] In this embodiment of the present invention, the communication module periodically sends a first charge prohibition message to the controller module via the CAN bus, based on the vehicle network being awake. As shown in Figure 4, the first charge prohibition message includes a signal consisting of "charging reservation request = charge prohibition" and a charging power limit.

[0092] Step 2018: The controller module controls the vehicle to be in a non-charging state according to the first charging prohibition message.

[0093] In one possible implementation, the reservation information includes a charging power limit, a reservation type, and charging-related information. The reservation type includes a daily reservation type. The charging-related information includes a second scheduled charging start time and a second scheduled charging end time. Step 201 may specifically include:

[0094] In step 201A, the communication module determines whether to charge the vehicle based on the second current time and the second scheduled charging start time. If so, execute step 201B; if not, execute step 201F.

[0095] In this embodiment of the present invention, the communication module determines whether the second current time reaches the second scheduled charging start time; if it is determined that the second current time reaches the second scheduled charging start time, it is determined that the vehicle is charged and step 201B is executed; if it is determined that the second current time does not reach the second scheduled charging start time, it is determined that the vehicle is not charged and step 201F is executed.

[0096] Step 201B: Based on the vehicle network being in an awake state, the communication module sends a second scheduled charging request message to the controller module through the vehicle network. The second scheduled charging request message includes a charging power limit and a second scheduled charging request.

[0097] In the embodiment of the present invention, as shown in Figure 3, the TBOX sends the second scheduled charging request message to the VCU via the gateway of the vehicle network. As shown in Figure 4, the second scheduled charging request is a "scheduled charging request = allow charging" request.

[0098] Step 201C: The controller module controls the vehicle to be in a charging state according to the second scheduled charging request.

[0099] In the embodiment of the present invention, the vehicle has been connected to an off-board charger, as shown in FIG4 , and the VCU controls the vehicle to enter the charging process and charge at high voltage.

[0100] Step 201D: The controller module determines whether to end charging the vehicle based on the charging power limit and the second current battery power and / or whether a stop charging message sent by the communication module is received. If so, execute step 201E; if not, execute step 201D.

[0101] In an embodiment of the present invention, the controller module determines whether the second current battery power reaches the charging power limit and / or whether a stop charging message sent by the communication module is received; if it is determined that the second current battery power reaches the charging power limit and / or a stop charging message sent by the communication module is received, it is determined to end charging of the vehicle and step 201E is executed; if it is determined that the second current battery power does not reach the charging power limit and the stop charging message sent by the communication module is not received, it is determined to continue charging the vehicle and step 201D is executed.

[0102] The stop charging message is sent by the communication module to the controller module based on the daily schedule type, the current charging status, the third current time, and the second scheduled charging end time. Before the controller module determines receipt of the stop charging message from the communication module, the communication module also determines whether to terminate vehicle charging based on the daily schedule type, the current charging status, the third current time, and the second scheduled charging end time. If the communication module determines that the vehicle charging is terminated, it sends the stop charging message to the controller module. If the communication module determines that the vehicle charging is to continue, it then determines whether to terminate vehicle charging based on the daily schedule type, the current charging status, the third current time, and the second scheduled charging end time. If the communication module determines that the vehicle charging is to continue, it then executes step 201A.

[0103] The current charging state includes a charging state or a charging end state. The communication module determines whether the third current time has reached the second scheduled charging end time based on the daily schedule type. If the third current time has reached the second scheduled charging end time, the communication module determines that charging of the vehicle has ended based on the current charging state including the charging state, and sends a stop charging message to the controller module. Alternatively, if the communication module determines that the third current time has reached the second scheduled charging end time, the communication module determines that charging of the vehicle has ended based on the current charging state including the charging end time. Alternatively, if the communication module determines that the third current time has not reached the second scheduled charging end time, the communication module determines that charging of the vehicle continues. Based on the daily schedule type, the communication module determines whether to end charging of the vehicle based on the current charging state, the third current time, and the second scheduled charging end time.

[0104] Step 201E: The controller module controls the vehicle to be in a non-charging state.

[0105] In the embodiment of the present invention, as shown in FIG4 , the VCU controls the entire vehicle to end the charging process and lower the high voltage.

[0106] Step 201F: The communication module determines whether the vehicle network is in the awake state. If so, step 201G is executed; if not, step 201A is executed.

[0107] In the embodiment of the present invention, the vehicle network may be in an awake state or a non-awakened state.

[0108] Step 201G: The communication module sends a second charging prohibition message to the controller module through the vehicle network.

[0109] In this embodiment of the present invention, the communication module periodically sends a second charge prohibition message to the controller module via the CAN bus, based on the vehicle network being awake. As shown in Figure 4, the second charge prohibition message includes a signal consisting of "charging reservation request = charge prohibition" and the charging power limit.

[0110] Step 201H: The controller module controls the vehicle to be in a non-charging state according to the second charging prohibition message.

[0111] In a possible implementation, step 201 further includes: step 202, the communication module obtains the vehicle operation status notification; and sends the vehicle operation status notification to the user equipment.

[0112] In an embodiment of the present invention, the vehicle operation status notification includes a charging completion status notification, which includes at least one of a charging completion prompt, a charged power level, reservation information, and a vehicle status, thereby prompting the user that the vehicle has completed charging.
