[0040] A second aspect of this application provides a charging adapter device, which includes a power input interface, a power selection circuit, a switch circuit, a microcontroller unit (MCU), and a power output interface.

[0041] The power input interface is connected to the power selection circuit and the switch circuit respectively. The power selection circuit is connected to the switch circuit and the power output interface respectively. The switch circuit is also connected to the microcontroller unit.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0065] In related technologies, users can insert the charging gun from a charging station into the charging port of an electric vehicle. After the charging station and the electric vehicle complete a handshake communication, the charging station outputs electrical energy to the charging port of the electric vehicle through the charging gun according to the output power preset by the developers. This achieves the purpose of charging the electric vehicle's battery. However, these related technologies suffer from low flexibility and poor safety when charging electric vehicles.

[0066] To address this, this application provides a charging control method. By establishing a communication connection with the vehicle to be charged and acquiring real-time status data of the battery device in the vehicle, the method determines the charging information to be executed for the vehicle. Based on the real-time status data of the battery device and the charging information to be executed, the method adjusts the charging parameters of the charging adapter and outputs electrical energy to the vehicle according to the adjusted charging parameters. This method can improve the flexibility and safety of charging electric vehicles.

[0067] This application describes a charging control method used in a charging adapter device as an example. However, it does not imply that this application's embodiments can only be applied to charging control in charging adapter devices.

[0068] Figure 1 This is a schematic diagram of the structure of a charging adapter device provided in an embodiment of this application. See also... Figure 1 The charging adapter A may include a power input interface a, a power selection circuit b, a switch circuit c, a microcontroller unit d, and a power output interface e.

[0069] from Figure 1 As can be seen, the power input interface a is used to connect to the power source, the power output interface e is used to connect to the battery pack in the vehicle to be charged, and the microcontroller d is used to connect to the various control devices in the vehicle to be charged.

[0070] The power selection circuit b is used, under the action of the microcontroller unit d, to adjust the parameters of the electrical energy output by the charging adapter A through the power output interface e. For example, the power selection circuit b can adjust the power value, current value, voltage value, etc. of the electrical energy output by the charging adapter A through the power output interface e, but this embodiment of the application does not limit this.

[0071] The on / off circuit c is used, under the action of the microcontroller d, to control whether the charging adapter A outputs electrical energy to the battery pack.

[0072] The microcontroller unit d is specifically used to execute any step in the charging control method provided in the embodiments of this application.

[0073] Optionally, the vehicle to be charged can be any electric vehicle such as an electric bicycle, electric motorcycle, or electric-assisted bicycle.

[0074] The control devices in the vehicle to be charged may include the battery management system (BMS) or battery MCU of the battery device in the vehicle to be charged, or the controller in the vehicle to be charged.

[0075] Optionally, the power input interface a can be a plug for connecting to a power source, and the power output interface e can be a plug for connecting to a battery pack. This application embodiment does not limit this.

[0076] The power source can be 220V, 110V or other voltage levels of electrical energy output from mains power or generator; this application does not limit this.

[0077] Optionally, the switching circuit c may include multiple switching transistors, and the switching circuit c can be powered on or off by controlling the conduction or disconnection of each switching transistor through the microcontroller d.

[0078] For example, when the switching circuit c is powered on, the power transmission between the power input interface a, the power selection circuit b, and the power output interface e can be disconnected, and the charging adapter A will then output power to the battery pack. When the switching circuit c is powered off, the power transmission between the power input interface a, the power selection circuit b, and the power output interface e can be connected, and the charging adapter A will not output power to the battery pack.

[0079] Figure 2 This is a schematic diagram illustrating an application scenario of a charging adapter device provided in an embodiment of this application. See also... Figure 2 In this application scenario, the components include a charging adapter A and a vehicle B to be charged.

[0080] One possible way, from Figure 2 As can be seen from (a) in the diagram, the vehicle B to be charged may include a battery device f, a controller h, and an input device s.

[0081] The battery device f may include a battery pack g, which may be composed of multiple batteries connected in series. Specifically, the battery pack g may be a lithium battery or other types of batteries.

[0082] The input device s can be an instrument panel in the vehicle B to be charged. The input device s can include an instrument MCU, an input module j, and a display module k.

[0083] In this case, the input module j can be a touch screen that can be triggered by the user or relevant technicians, or it can be a device that includes corresponding triggerable buttons. The user can input some possible instructions through the input module j to indicate the parameters that the user expects to charge the vehicle B to be charged.

[0084] The microcontroller unit d in the charging adapter A can be connected to the controller h, the controller h is connected to the battery pack g, and the instrument MCU can be connected to the controller h, the input module j, and the display module k respectively.

[0085] For details on the connection structure, please refer to [link / reference]. Figure 2 As in (a), the embodiments of this application will not be repeated here.

[0086] For example, the user can input the desired charging level and / or charging parameters through the input module j, and the user-input charging level and / or charging parameters can be displayed through the display module k. Additionally, the display module k can also display the current status of the vehicle B to be charged, such as vehicle speed, remaining battery power, and power steering level; however, this embodiment of the application does not limit this information.

[0087] One possible way, from Figure 2 As can be seen in (b) above, the battery device f may also include a battery pack g and a battery MCU.

[0088] In this case, the microcontroller d in the charging adapter A can be connected to the battery MCU and the controller h respectively, the battery MCU is connected to the battery pack g, and the instrument MCU can be connected to the controller h, the input module j and the display module k respectively.

[0089] The battery MCU can be used to monitor the status of the battery pack g.

[0090] In addition, the controller h can also be connected to the battery pack g to directly obtain the status data of the battery pack g through the controller h. This application embodiment does not limit this.

[0091] For details on the connection structure, please refer to [link / reference]. Figure 2 As in (b), the embodiments of this application will not be repeated here.

[0092] Generally, when charging adapter A is connected to the vehicle B to be charged, charging adapter A can connect to the battery MCU, controller h, and / or instrument MCU. At this time, charging adapter A can also supply power to the battery MCU, controller h, and / or instrument MCU, and the connection method can be arbitrary, such as connecting to the battery MCU, controller h, and / or instrument MCU through the power output interface e. This embodiment of the application does not limit this. In this way, even when the battery pack in the vehicle B to be charged has zero charge, the battery MCU, controller h, and / or instrument MCU can still be powered on and operate normally and communicate with the microcontroller d.

[0093] The charging control method provided in the embodiments of this application will be explained in detail below.

[0094] Figure 3 A flowchart of a charging control method provided in this application is shown. This method can be applied to the microcontroller d in the charging adapter A described above. See also... Figure 3 This application provides a charging control method, including:

[0095] Step 1001: Establish a communication connection with the vehicle to be charged and obtain real-time status data and input parameters of the battery device in the vehicle to be charged.

[0096] Optionally, the vehicle to be charged can be the aforementioned vehicle B. Establishing a communication connection with the vehicle to be charged can refer to establishing a communication connection with the battery MCU and / or controller in the vehicle to be charged. Specifically, it can be established based on the Controller Area Network (CAN) protocol, the USART serial communication protocol, or other communication protocols. This application embodiment does not limit this.

[0097] Optionally, the battery device can be the aforementioned battery device f.

[0098] The real-time status data may refer to the real-time status of the battery pack in the battery device. This real-time status data can be used to indicate whether the battery pack has power and / or the specific amount of power in the battery pack. The real-time status data includes at least one of the following: remaining power, operating voltage, and operating current.

[0099] This input parameter can be used to indicate the parameters of electrical energy that can be input to the battery device, such as the input power range, input voltage range, and / or input current range supported by the battery device.

[0100] Generally, if the electrical energy output from the charging adapter or other charger to the battery device does not meet the input parameters, the battery device can disconnect the charging channel between the charging adapter and the battery device.

[0101] It is worth noting that since the real-time status data can be used to indicate whether the battery pack has power and the specific amount of power in the battery pack, and the real-time status data can include the remaining power, operating voltage, and operating current, the charging adapter can determine whether the vehicle to be charged needs to be charged at present based on the real-time status data, which facilitates subsequent charging control.

[0102] Step 1002: Determine the charging information to be performed for the vehicle to be charged.

[0103] Optionally, the charging information to be performed can be used to indicate the maximum parameters that the charging adapter can currently output electrical energy to the vehicle to be charged or the battery pack in the vehicle to be charged, such as the power range or voltage range.

[0104] The charging information to be executed can be the desired charging parameters input by relevant technicians or users through the input device in the vehicle to be charged, or the charging parameters determined by the battery MCU, controller, instrument MCU in the vehicle to be charged, or the microcontroller unit in the charging adapter according to the actual situation. This application embodiment does not limit this.

[0105] It is worth noting that since the charging information to be executed can be used to indicate the parameters that the charging adapter can currently output electrical energy to the vehicle to be charged, and this charging information can be input by relevant technicians or users, or determined by the battery MCU, controller, instrument MCU in the vehicle to be charged, or the microcontroller unit in the charging adapter according to the actual situation, the parameters of the electrical energy output by the charging adapter to the vehicle to be charged can be adjusted in real time through this charging information to improve the flexibility of charging control.

[0106] Step 1003: Adjust the charging parameters of the charging adapter according to the real-time status data of the battery device, the input parameters and the charging information to be performed, and output electrical energy to the vehicle to be charged according to the adjusted charging parameters.

[0107] Optionally, the charging parameters of the charging adapter may include the output power, output voltage and / or output current of the charging adapter.

[0108] The power output to the vehicle to be charged according to the adjusted charging parameters can be the output of power, voltage and current to the battery pack in the battery device of the vehicle to be charged, which meets the power, voltage and current indicated by the adjusted charging parameters.

[0109] It's worth noting that when charging the battery pack in the vehicle, the charging stage generally needs to be determined based on the battery pack's charge level, such as trickle charging, constant current charging, or constant voltage charging. Specifically, when the battery pack's charge level is very low, such as less than or equal to 10%, it can be determined to be in the trickle charging stage, where a constant current is used to slowly charge the battery pack. When the battery pack's charge level is greater than 10% and less than or equal to 80%, it can be determined to be in the constant current charging stage, where a constant current is used to fast charge the battery pack. Finally, when the battery pack's charge level is greater than 80% and less than or equal to 100%, it can be determined to be in the constant current charging stage, where a small current is used for float charging until charging is complete.

[0110] In other words, the required or allowed electrical energy parameters of the battery pack vary depending on its charge level.

[0111] It is worth noting that the real-time status data is used to indicate the real-time status of the battery pack, such as remaining charge or operating voltage. The charging adapter can then determine the charging stage for the battery pack based on this data. The input parameters indicate the parameters of electrical energy that can be input to the battery device. The charging information to be executed can be input by relevant technicians or users through input devices in the vehicle to be charged, or it can be determined by the battery MCU, controller, instrument MCU in the vehicle to be charged, or the microcontroller unit in the charging adapter, based on actual conditions, to indicate the parameters that the charging adapter currently needs to output electrical energy to the vehicle to be charged.

[0112] Therefore, by adjusting the charging parameters of the charging adapter based on the real-time status data of the battery device, the input parameters, and the charging information to be executed, the parameters of the electrical energy output by the charging adapter can be flexibly adjusted. It can also ensure that the electrical energy output by the charging adapter to the vehicle to be charged according to the adjusted charging parameters meets the current charging stage of the battery pack, thereby ensuring the safety of charging the battery pack.

[0113] In this embodiment of the application, by establishing a communication connection with the vehicle to be charged and obtaining the real-time status data and input parameters of the battery device in the vehicle to be charged, the charging adapter can determine whether the vehicle to be charged needs to be charged at present based on the real-time status data, so as to facilitate subsequent charging control.

[0114] By determining the charging information to be executed for the vehicle to be charged, and adjusting the charging parameters of the charging adapter based on the real-time status data of the battery pack and the charging information to be executed, the charging adapter outputs electrical energy to the vehicle to be charged according to the adjusted charging parameters. Since the real-time status data indicates the real-time status of the battery pack, such as remaining charge or operating voltage, the charging adapter can determine the charging stage for the battery pack based on this data. The charging information to be executed can be input by relevant technicians or users through input devices in the vehicle to be charged, or it can be parameters determined by the battery MCU, controller, instrument MCU in the vehicle to be charged, or the microcontroller unit in the charging adapter, based on actual conditions, indicating the current electrical energy output that the charging adapter needs to provide to the vehicle to be charged.

[0115] Therefore, by adjusting the charging parameters of the charging adapter based on the real-time status data of the battery device, the input parameters, and the charging information to be executed, the parameters of the electrical energy output by the charging adapter can be flexibly adjusted. It can also ensure that the electrical energy output by the charging adapter to the vehicle to be charged according to the adjusted charging parameters meets the current charging stage of the battery pack, thereby ensuring the safety of charging the battery pack.

[0116] This can improve the flexibility and safety of charging electric vehicles.

[0117] In one possible implementation, see [link to relevant documentation]. Figure 4 The system determines the charging information to be performed for the vehicle to be charged, including:

[0118] Step 1004: If the charging parameters to be executed as indicated by the user are obtained, then the charging parameters to be executed are used as the charging information to be executed.

[0119] Optionally, the charging parameters to be executed include at least one of the following: charging level, current range to be executed, power range to be executed, and voltage range to be executed.

[0120] Optionally, the charging level can be set in advance by relevant technical personnel according to actual needs for the charging adapter. The charging level can also indicate the corresponding power range to be executed, current range to be executed, and / or voltage range to be executed.

[0121] For example, the charging level can be divided into level 1, level 2, and level 3. Specifically, level 1 indicates the power range to be executed [0, 159W], level 2 indicates the power range to be executed [160W, 259W], and level 3 indicates the power range to be executed [260W, 399W].

[0122] It is understandable that the charging parameters to be executed may also exclude the charging level and directly include the power range, current range and / or voltage range to be executed.

[0123] The current range to be executed and the voltage range to be executed can be set according to the charging level and / or the power range to be executed, and this application embodiment does not limit this.

[0124] Optionally, the charging parameters to be executed can be input by the user through the aforementioned input device s. Specifically, the charging parameters to be executed can also be obtained by parsing the power selection command or gear selection command input by the user through the input device s, which is not limited in this embodiment.

[0125] It is worth noting that, if the charging parameters to be executed as indicated by the user are obtained, it can be determined that the user has input the desired charging parameters through the input device s. In this case, the charging parameters to be executed need to be used as the charging information to facilitate subsequent charging of the vehicle and / or battery pack according to the user's desired charging parameters.

[0126] Step 1005: If the charging parameters to be executed as indicated by the user are not obtained, the charging parameters corresponding to the lowest charging level shall be used as the charging information to be executed.

[0127] Optionally, the lowest charging level may refer to the charging level with the lowest indicated voltage, current and / or power among the various charging levels preset by relevant technicians.

[0128] For example, among the three charging levels mentioned above (level 1, level 2, and level 3), level 1 indicates the smallest range of power to be executed, so level 1 is the lowest charging level.

[0129] The charging parameters corresponding to the lowest charging level may include the charging level, the power range to be executed, the current range to be executed, and / or the voltage range to be executed, which are not limited in this application embodiment.

[0130] It is worth noting that if the user-indicated charging parameters are not received, it can be determined that the user did not input the desired charging parameters through the input device s, or that there is a communication problem between the charging adapter and the vehicle to be charged, causing the charging adapter to fail to receive the charging parameters. In this case, the lowest charging level should be used as the charging information to be executed. This ensures that when the charging parameters of the charging adapter are subsequently adjusted based on the aforementioned real-time status data and the charging information to be executed, the adjusted charging parameters will not be too high, thus avoiding damage to the vehicle to be charged or its battery pack, thereby improving the safety of charging electric vehicles.

[0131] It is understandable that, whether the charging parameters to be executed are obtained or not, the charging adapter can determine different charging information to be executed in order to adjust the charging parameters of the charging adapter. This can improve the flexibility of determining the charging information to be executed and adjusting the charging parameters of the charging adapter.

[0132] In one possible implementation, see [link to relevant documentation]. Figure 5 The charging adapter adjusts its charging parameters based on the real-time status data of the battery device, the input parameters, and the charging information to be performed, and outputs electrical energy to the vehicle to be charged according to the adjusted charging parameters, including:

[0133] Step 1006: Determine the real-time charging stage of the battery device based on the real-time status data, and determine the allowable power range corresponding to the real-time charging stage based on the input power range supported by the battery device indicated by the input parameters.

[0134] Optionally, the real-time charging stage can refer to the charging stage corresponding to the battery pack when the battery pack in the battery device is being charged. The real-time charging stage can be the trickle charging stage, constant current charging stage, or constant voltage charging stage mentioned above, specifically determined based on the real-time status data.

[0135] Optionally, the input parameter is used to indicate the input power range supported by the battery device, which specifically refers to the power range corresponding to the entire process of the battery device's charge from 0% to 100%. That is, the input power range can indicate the maximum and minimum input power of the battery device.

[0136] For example, if the real-time charging phase is a trickle charging phase, then the range with the smaller input power can be determined from the input power range as the allowable power range corresponding to the trickle charging phase.

[0137] If the real-time charging stage is a constant current charging stage, then the range with the larger input power can be determined from the input power range as the allowable power range corresponding to the constant current charging stage.

[0138] If the real-time charging stage is a constant voltage charging stage, then a suitable range of input power can be determined from the input power range as the allowable power range corresponding to the constant voltage charging stage.

[0139] The specific settings can be determined by relevant technical personnel based on actual parameters, or the allowable power range can be determined based on the actual state of the battery device. This application embodiment does not limit this.

[0140] Optionally, the allowable power range can be used to indicate the maximum and / or minimum allowable input power when the battery pack is being charged during the real-time charging phase. Generally, the minimum allowable input power can be 0.

[0141] The allowable power range can also refer to the safe power range for charging the battery pack. That is, when the power supplied to the battery device or the battery pack meets the allowable power range, the risk of damage to the battery device or the battery pack can be greatly reduced.

[0142] For example, if the real-time charging stage is a constant current charging stage, then the allowable power range can be [0, 180W]. Specifically, the allowable power range corresponding to each charging stage can be determined according to the actual electrical parameters of the battery pack, and this application embodiment does not limit this.

[0143] This allows for the determination of the charging stage and corresponding allowable power range of the battery device during charging, facilitating flexible adjustment of the charging adapter's charging parameters based on this allowable power range. Furthermore, since this allowable power range aligns with the battery device's input power range, it ensures that adjusting the charging adapter's charging parameters using the real-time status data and the charging information to be executed will not damage the battery device.

[0144] Step 1007: Determine the charging power range based on the charging information to be executed.

[0145] Optionally, the power range to be charged can be used to indicate the maximum power range that the charging adapter can currently output.

[0146] For example, if the charging information to be executed includes a power range to be executed, the power range to be executed can be directly read from the charging information to be executed.

[0147] If the charging information to be executed includes the charging level, the voltage range to be executed, and / or the current range to be executed, then the power range to be executed corresponding to the charging level, the voltage range to be executed, and / or the current range to be executed can be calculated or matched based on the charging level, the voltage range to be executed, and / or the current range to be executed. This application embodiment does not limit this.

[0148] Step 1008: Adjust the charging parameters of the charging adapter according to the allowable power range and the power range to be charged, and charge the vehicle to be charged according to the adjusted charging parameters.

[0149] It is worth noting that, since the allowable power range can be used to indicate the maximum and minimum allowable input power of the battery pack during the real-time charging phase, the power range to be charged can be used to indicate the maximum power range that the charging adapter can currently output. Therefore, based on the allowable power range and the power range to be charged, a charging parameter that is as large as possible but not greater than the maximum allowable input power of the battery pack can be determined, thereby improving the flexibility and safety of charging electric vehicles.

[0150] In one possible implementation, the charging parameters of the charging adapter are adjusted according to the allowable power range and the power range to be charged, and the vehicle to be charged is charged according to the adjusted charging parameters, including:

[0151] If the maximum allowable power value indicated by the allowable power range is greater than or equal to the maximum charging power indicated by the power range to be charged, then the charging power of the charging adapter meets the power range to be charged, and the vehicle to be charged is charged based on the power that meets the power range to be charged.

[0152] Optionally, the maximum allowable power value can refer to the maximum value within the allowable power range, and the minimum value within the allowable power range is the minimum allowable power value. The maximum charging power can refer to the maximum value within the power range to be charged, and the minimum value within the power range to be charged is the minimum charging power.

[0153] Optionally, the power that meets the charging power range can be any power value between the maximum and minimum charging power of the charging power range. Additionally, the specific power output during charging can be adjusted based on parameters such as the battery's actual charge level and voltage.

[0154] For example, if the allowable power range is [0, 180W], then the maximum allowable power value is 180W. If the power range to be charged is [0, 159W], then the maximum charging power is 159W. It can be seen that the maximum allowable power value is greater than or equal to the maximum charging power.

[0155] It is worth noting that since the minimum allowable input power can be 0, the charging parameters of the charging adapter generally only need to be adjusted according to the maximum allowable power value.

[0156] Since the maximum allowable power value is greater than or equal to the maximum charging power, even if the charging adapter outputs power to the battery pack and charges it according to the maximum charging power, it will not exceed the maximum allowable power value of the battery pack. Therefore, it can be determined that charging the battery pack according to the charging power range will not cause damage to the battery pack.

[0157] If the maximum allowable power value is less than the maximum charging power, and greater than or equal to the minimum charging power indicated by the power range to be charged, then the charging power of the charging adapter meets the allowable power range, and the vehicle to be charged is charged based on the power that meets the allowable power range.

[0158] Optionally, the power that satisfies the allowable power range can refer to any power value between the maximum allowable power value and the minimum allowable power value of the allowable power range.

[0159] For example, if the allowable power range is [0, 180W], then the maximum allowable power value is 180W. If the power range to be charged is [160W, 259W], then the maximum charging power is 259W, and the minimum charging power is 160W. It can be seen that the maximum allowable power value is less than the maximum charging power, and greater than or equal to the minimum charging power.

[0160] It is worth noting that since the maximum allowable power value is less than the maximum charging power and greater than or equal to the minimum charging power, if the charging adapter outputs power to the battery pack at a power greater than the maximum allowable power value but less than the maximum charging power, the battery pack may be damaged. Therefore, it is necessary to ensure that the charging power of the charging adapter meets the allowable power range. Specifically, the charging power of the charging adapter can be less than the maximum allowable power indicated by the allowable power range.

[0161] If the maximum allowable power value is less than the minimum charging power, the charging power of the charging adapter is adjusted to the preset charging power, and the vehicle to be charged is charged based on the preset charging power.

[0162] Optionally, the preset charging power may refer to the power range corresponding to the lowest charging level, or it may refer to the power for trickle charging of the battery pack, or it may be a power value set by relevant technical personnel that is less than or equal to the minimum allowable power. This application embodiment does not limit this.

[0163] For example, if the allowable power range is [0, 180W], then the maximum allowable power value is 180W. If the power range to be charged is [260W, 399W], then the maximum charging power is 399W, and the minimum charging power is 260W. It can be seen that the maximum allowable power value is less than the minimum charging power.

[0164] It is worth noting that since the maximum allowable power value is less than the minimum charging power, even if the power is output to the battery pack at the minimum charging power, it exceeds the maximum allowable input power of the battery pack. This may damage the battery pack. Therefore, the charging power of the charging adapter is adjusted to the preset charging power.

[0165] It is worth noting that the charging parameters of the charging adapter can be flexibly adjusted according to the allowable power range and the power range to be charged, and it can be ensured that the charging adapter will not damage the battery pack when it outputs power and charges the battery pack according to the adjusted charging parameters. In this way, the flexibility and safety of charging electric vehicles can be improved.

[0166] In one possible implementation, see [link to relevant documentation]. Figure 6 To obtain real-time status data and input parameters of the battery device in the vehicle to be charged, including:

[0167] Step 1009: Send a data acquisition request to the battery device and receive the real-time status data sent by the battery device.

[0168] Optionally, see above. Figure 2 Specifically, (b) can send the data acquisition request and the input parameters to the battery MCU in the battery device.

[0169] The data acquisition request may be an instruction used to enable the battery MCU in the battery device to detect the real-time status data of the battery pack and the input parameters, and to send the real-time status data and the input parameters to the charging adapter. This application embodiment does not limit this.

[0170] Specifically, the real-time status data can be received in real time through the aforementioned microcontroller unit.

[0171] This allows for accurate and timely acquisition of the real-time status data.

[0172] In one possible implementation, see [link to previous section] Figure 6 After sending a data acquisition request to the battery device, the method further includes:

[0173] Step 1010: If the real-time status data sent by the battery device is not received within a preset time, a data acquisition request is sent to the controller of the vehicle to be charged.

[0174] Optionally, the preset time can be set by relevant technical personnel according to actual needs. Generally, the preset time can be set to a shorter duration, such as 2 seconds, 5 seconds or other possible durations. This application embodiment does not limit this.

[0175] Optionally, the data acquisition request can also be used to instruct the controller to send the real-time status data to the charging adapter.

[0176] It is worth noting that if the real-time status data sent by the battery device is not received within the preset time, it indicates that the battery in the battery device is out of power, the battery MCU is damaged, or the communication between the battery MCU and the microcontroller unit in the charging adapter has failed. Therefore, it is necessary to send the data acquisition request to the controller of the vehicle to be charged.

[0177] Step 1011: Receive the real-time status data and input parameters sent by the controller.

[0178] Understandably, the data acquisition request is used to instruct the battery device and / or the controller to send the real-time status data and the input parameters to the charging adapter.

[0179] This can improve the reliability of the data retrieval request.

[0180] In one possible implementation, obtaining real-time status data and input parameters of the battery device in the vehicle to be charged further includes:

[0181] Send a data acquisition request to the controller of the vehicle to be charged.

[0182] Optionally, see above. Figure 2 In (a), if the battery device f only includes the battery pack g and does not include other processing devices, the real-time status data can be obtained by sending the data acquisition request to the controller h.

[0183] Receive the real-time status data and input parameters sent by the controller.

[0184] This increases the flexibility in obtaining the real-time status data and the input parameters.

[0185] In one possible implementation, see [link to relevant documentation]. Figure 7 After obtaining the real-time status data and input parameters of the battery device in the vehicle to be charged, the process also includes:

[0186] Step 1012: Determine the initial charge level of the battery in the battery device as indicated by the real-time status data.

[0187] Alternatively, the battery in the battery device can refer to the battery pack in the battery device.

[0188] Optionally, the initial charge may refer to the charge level of the battery pack at the current moment.

[0189] Step 1013: If the initial charge is 0, then output electrical energy to the battery at a preset charging power.

[0190] Optionally, if the initial charge is 0, the battery or battery pack may be supplied with electrical energy at the trickle charging power indicated by the preset charging power. This application embodiment does not limit this.

[0191] It is worth noting that if the initial charge is 0, it indicates that the battery or battery pack may have entered a dormant state and needs to be charged first to wake up and activate the battery or battery pack.

[0192] Step 1014: Monitor the real-time battery level, and when the real-time battery level is greater than the trickle charge level, send a parameter acquisition command to the controller of the vehicle to be charged to obtain the charging parameters to be executed as indicated by the user.

[0193] Optionally, the real-time power level may refer to the power level of the battery during the process of outputting electrical energy to the battery at the preset charging power.

[0194] Optionally, the trickle charge capacity may refer to the battery's charge level when the trickle charge phase is completed.

[0195] Therefore, if the real-time charge of the battery is greater than the trickle charge, it indicates that the battery has stored a certain amount of electrical energy and has completed trickle charging.

[0196] In addition, when the controller receives the parameter acquisition instruction, it can forward the parameter acquisition instruction to the instrument MCU of the vehicle to be charged. This application embodiment does not limit this.

[0197] The parameter acquisition instruction can be used to enable the controller or the instrument MCU to acquire the charging parameters to be executed input by the user, and the controller can then send the charging parameters to be executed to the charging adapter.

[0198] In this way, the battery or battery pack can be activated even when its charge is 0%, and the charging parameters to be executed can be reliably obtained.

[0199] Step 1015: If the initial power is not 0, send the parameter acquisition instruction to the controller based on the real-time status data to obtain the charging parameters to be executed as indicated by the user.

[0200] It is worth noting that since the real-time status data can indicate the specific charge level of the battery or battery pack, it is possible to determine whether the battery or battery pack needs to be charged based on the real-time status data. When charging is required, the parameter acquisition command is sent to the controller. In this way, it is possible to flexibly determine whether to send the parameter acquisition command to the controller based on the actual charging needs, thereby improving the flexibility of charging electric vehicles.

[0201] In one possible implementation, sending the parameter acquisition instruction to the controller based on the real-time status data includes:

[0202] The system determines whether the battery device needs charging based on the real-time status data.

[0203] For example, if the real-time status data includes the battery pack's charge level in the battery device, it can be determined whether the battery pack needs charging by determining the charge level. Specifically, if the battery pack's charge level is 100%, it can be determined that the battery device does not need charging; otherwise, it can be determined that the battery device needs charging.

[0204] If necessary, a parameter acquisition command is sent to the controller of the vehicle to be charged.

[0205] Optionally, the parameter acquisition instruction is used to instruct the controller to acquire the charging parameters to be executed and send the charging parameters to be executed to the charging adapter.

[0206] In addition, the charging parameters to be executed are input to the vehicle to be charged by triggering the input device of the vehicle to be charged.

[0207] That is, the charging parameters to be executed are input into the vehicle to be charged by relevant technicians or users through the input device of the vehicle to be charged.

[0208] If not required, the battery pack can be continuously monitored in real time and new real-time status data can be obtained. When the new real-time status data indicates that the battery pack's charge is less than 100%, the charging parameters of the charging adapter can be adjusted according to the new real-time status data and the charging information to be performed, and the power can be output to the vehicle to be charged according to the adjusted charging parameters.

[0209] Furthermore, when the battery device does not require charging, the charging adapter can disconnect the power transmission between the charging adapter and the vehicle to be charged via a switching circuit within the charging adapter. This prevents continuous charging of the vehicle's battery device, which could damage the vehicle and / or the battery device.

[0210] In this way, based on the actual state data of the battery device, specifically the battery pack's charge level, it can be flexibly determined whether to send a parameter acquisition command to the controller of the vehicle to be charged, thereby improving the flexibility and safety of charging electric vehicles.

[0211] In one possible approach, during the process of adjusting the charging parameters of the charging adapter based on the real-time status data of the battery device and the charging information to be executed, and outputting electrical energy to the vehicle to be charged according to the adjusted charging parameters, the voltage of the battery device gradually increases as the battery power increases. Therefore, it is necessary to determine the real-time status data of the battery device in real time, and adjust the charging parameters of the charging adapter based on the new real-time status data and the charging information to be executed.

[0212] In this way, the charging stage of the battery pack can be accurately and timely determined based on the real-time status data of the battery device, and the real-time status data of the battery device can be adjusted accurately and timely. This improves the flexibility, safety, and immediacy of charging electric vehicles.

[0213] In one possible approach, if the charging adapter cannot establish a correct communication connection with the vehicle to be charged, that is, if the charging adapter fails to communicate with the vehicle to be charged and the charging adapter cannot obtain the real-time status data and / or charging parameters of the battery from the vehicle to be charged, then the charging parameters corresponding to the lowest charging level can be used as the charging information to be executed.

[0214] Subsequently, the charging parameters of the charging adapter can be adjusted using the charging parameters corresponding to the lowest charging level, and electrical energy can be output to the vehicle to be charged according to the adjusted charging parameters. In this way, it can be ensured that the adjusted charging parameters are not too high, so as to avoid damaging the vehicle to be charged or the battery pack in the vehicle to be charged, thereby improving the safety of charging electric vehicles.
