[0036] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments of this application, including various details to aid understanding. These should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this application. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0037] In the description of this application, unless otherwise stated, " / " means "or", for example, A / B can mean A or B; "and / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. The various numerical designations such as "first", "second", etc., involved in this application are only for the convenience of description and are not used to limit the scope of the embodiments of this application, nor do they indicate the order of events.

[0038] Please see Figure 1 , Figure 1 This is a schematic diagram of a vehicle battery replacement method provided in an embodiment of this application. This method can be applied to vehicles. Figure 1 As shown, the method may include, but is not limited to, the following steps:

[0039] Step S101: In response to receiving the handshake information sent by the battery swapping station, determine whether a shutdown signal has been received.

[0040] For example, after a driver enters a battery swapping station, the vehicle's battery swapping controller establishes communication with the station's controller, and the station sends a handshake message to the vehicle. Upon receiving the handshake message, the vehicle determines whether the driver has sent an engine shutdown signal.

[0041] In one embodiment of this application, the vehicle described above can be a mining truck with a replaceable battery.

[0042] Step S102: In response to receiving the engine shutdown signal, determine whether a battery swapping signal has been received within the first time period after receiving the engine shutdown signal.

[0043] In one embodiment of this application, the vehicle is in a high-voltage energized state and stops outputting torque during the first time period.

[0044] For example, within the first period (e.g., 120 seconds) after receiving a shutdown signal from the driver, the vehicle's VCU (Vehicle Control Unit) does not send a high-voltage command to the vehicle's BMS (Battery Management System), so that the BMS can maintain a high-voltage power-on state while controlling the vehicle's motor output torque to be 0.

[0045] Step S103: In response to receiving a battery swapping signal within the first time period, perform a battery swapping operation.

[0046] For example, in response to the driver turning on the vehicle's battery swapping switch during the first time period, the battery swapping operation is performed in coordination with the battery swapping station.

[0047] By implementing the embodiments of this application, the vehicle can maintain a high-voltage power-on state for a period of time after receiving a handshake message from the battery swapping station and turning off the engine, thereby enabling immediate execution of the battery swapping operation upon receiving a battery swapping command. This reduces the number of power cycles during battery replacement, alleviates wear and tear on electrical components, and improves the vehicle's battery swapping efficiency.

[0048] In one implementation, after receiving a handshake message from the battery swapping station and shutting down the engine, if a battery swapping signal is received within a certain period, a battery swapping operation can be performed in coordination with the battery swapping station. For an example, please refer to [link to example]. Figure 2 , Figure 2 This is a schematic diagram of another vehicle battery replacement method provided in an embodiment of this application. This method can be applied to vehicles. Figure 2 As shown, the method may include, but is not limited to, the following steps:

[0049] Step S201: In response to receiving the handshake information sent by the battery swapping station, determine whether a shutdown signal has been received.

[0050] In the embodiments of this application, step S201 can be implemented in any of the ways described in the embodiments of this application. The embodiments of this application do not limit this, nor will they be described in detail.

[0051] Step S202: In response to receiving the engine shutdown signal, determine whether a battery swapping signal has been received within the first time period after receiving the engine shutdown signal.

[0052] In the embodiments of this application, step S202 can be implemented in any of the ways described in the embodiments of this application. The embodiments of this application do not limit this, nor will they be described in detail.

[0053] Step S203: In response to receiving a battery swapping signal within the first time period, perform battery swapping preparation operation.

[0054] In one alternative implementation, the above-mentioned battery swapping preparation operation may include the following steps:

[0055] A1: Under high voltage power-on state, control the power take-off to open the brim to the first designated position.

[0056] For example, a command to open the hood is sent to the vehicle's battery swapping controller, causing the battery swapping controller to control the power take-off unit to open the hood to a first specified position.

[0057] In the embodiments of this application, the first designated location is a location where the battery can be removed.

[0058] It should be noted that when replacing the battery in a mining truck, the battery compartment visor needs to be opened to remove the battery. Opening the visor requires the vehicle's high-voltage power supply to control solenoid valves and other devices to perform the necessary operations.

[0059] A2: In response to the visor being opened to the first designated position, a high-voltage power-down operation is performed on the vehicle's battery management system (BMS).

[0060] For example, a proximity limit switch is pre-installed near a first designated position. After the cap brim is opened to the first designated position, the proximity limit switch sends a cap brim arrival signal to the VCU. Upon receiving the cap brim arrival signal, the VCU sends a high-voltage command to the BMS to perform a high-voltage power-down operation on the BMS.

[0061] A3: In response to the completion of the high-voltage power operation, disconnect the constant power supply to the BMS and the wake-up signal path of the BMS.

[0062] For example, in response to receiving the high-voltage power-off completion signal from the BMS, the VCU controls the battery swapping controller to unlock the mechanical locking device and cut off the constant power supply to the BMS and the wake-up signal path of the BMS.

[0063] Step S204: In response to the completion of the battery swapping preparation operation, send a battery swapping ready signal to the battery swapping station.

[0064] In one embodiment of this application, the battery swapping readiness signal is used by the battery swapping station to replace the vehicle's battery.

[0065] For example, the vehicle's VCU sends a battery swapping ready signal to the vehicle's battery swapping controller, which then forwards the signal to the battery swapping station.

[0066] Step S205: Receive the battery swapping completion signal sent by the battery swapping station.

[0067] For example, the vehicle's battery swapping controller receives a battery swapping completion signal from the battery swapping station, and then forwards the battery swapping completion signal to the VCU.

[0068] Step S206: Perform the final battery swap operation.

[0069] In one alternative implementation, the above-mentioned battery swapping completion operation may include the following steps:

[0070] B1: Restore the normal power and wake-up signal path of the BMS.

[0071] For example, the vehicle's VCU sends a command to the battery swapping controller to close the mechanical locking device to restore the BMS constant power and wake-up signal path.

[0072] B2: Perform a high-voltage power-on operation on the BMS.

[0073] For example, after the BMS initialization is complete, the VCU sends a high-voltage power-on command to the BMS so that the BMS can perform a high-voltage power-on operation.

[0074] B3: Under high voltage power-on state, control the power take-off to lower the brim to the second designated position.

[0075] For example, when the VCU receives the high-voltage power-on completion signal from the BMS, it sends a command to the battery swapping controller to lower the brim, causing the battery swapping controller to control the power take-off unit to lower the brim to the second designated position.

[0076] B4: In response to the cap brim falling back to the second designated position, it is confirmed that the battery swapping final operation has been completed.

[0077] For example, a proximity limit switch can be pre-installed at a second designated location. In response to the cap positioning signal sent by the proximity limit switch, it can be determined that the battery swapping operation has been completed.

[0078] By implementing the embodiments of this application, the vehicle can maintain a high-voltage power-on state for a period of time after receiving a handshake message from the battery swapping station and turning off the engine, thereby enabling immediate execution of the battery swapping operation upon receiving a battery swapping command. This reduces the number of power cycles during battery replacement, alleviates wear and tear on electrical components, and improves the vehicle's battery swapping efficiency.

[0079] In one implementation, after the vehicle battery is replaced, the vehicle's high-voltage power supply can be maintained for a period of time to facilitate driver operation. For an example, please refer to [link to example]. Figure 3 , Figure 3 This is a schematic diagram illustrating another method for replacing a vehicle battery provided in an embodiment of this application. This method can be applied to vehicles. Figure 3 As shown, the method may include, but is not limited to, the following steps:

[0080] Step S301: In response to receiving the handshake information sent by the battery swapping station, determine whether a shutdown signal has been received.

[0081] In the embodiments of this application, step S301 can be implemented in any of the embodiments of this application. The embodiments of this application do not limit this and will not be described in detail.

[0082] Step S302: In response to receiving the engine shutdown signal, determine whether a battery swapping signal has been received within the first time period after receiving the engine shutdown signal.

[0083] In the embodiments of this application, step S302 can be implemented in any of the embodiments of this application. The embodiments of this application do not limit this and will not be described in detail.

[0084] Step S303: In response to receiving a battery swapping signal within the first time period, perform a battery swapping operation.

[0085] In the embodiments of this application, step S303 can be implemented in any of the embodiments of this application. The embodiments of this application do not limit this and will not be described in detail.

[0086] Step S304: Maintain high voltage power supply and stop outputting torque during the second time period after the battery swapping operation is completed.

[0087] Specifically, during the second period after the battery swapping operation is completed, the BMS is kept powered on at high voltage and the output torque is stopped.

[0088] In some embodiments of this application, the above method may further include: generating an abnormality prompt message in response to receiving a battery swapping signal during the second time period.

[0089] Specifically, during the second period after the battery swapping operation is completed, a battery swapping signal is received, an abnormality alert is generated, and this alert is provided to the vehicle driver. For example, an audible alarm may be issued.

[0090] By implementing the embodiments of this application, a high-voltage power-on state can be maintained and torque output can be stopped during the second period after the battery swapping operation is completed. This allows users to drive away the vehicle promptly after the battery is depleted, improving the user experience.

[0091] In some embodiments of this application, the above method may further include: starting the vehicle in response to not receiving a battery swapping signal and receiving a start signal during a first time period.

[0092] Specifically, in response to not receiving a battery swapping signal during the first time period, but receiving a vehicle start signal (e.g., key unlocking signal), the vehicle is started normally.

[0093] In some embodiments of this application, the above method may further include: in response to not receiving a battery swapping signal during a first time period, sequentially performing a high-voltage power-off operation and a low-voltage power-off operation.

[0094] Specifically, in response to not receiving a battery swapping signal instructing the vehicle to perform a battery swap within the first time period, the VCU sends a high-voltage down-voltage signal to the BMS, causing the BMS to reduce its high voltage, and subsequently the entire vehicle to reduce its low voltage.

[0095] As an example, please see Figure 4a , Figure 4b and Figure 4c , Figure 4a This is a schematic diagram illustrating a vehicle battery replacement process provided in an embodiment of this application. Figure 4b This is a schematic diagram of another vehicle battery replacement process provided in an embodiment of this application. Figure 4c This is a schematic diagram illustrating another vehicle battery replacement process provided in an embodiment of this application. For example... Figure 4a As shown, after the vehicle establishes communication with the battery swapping station, the vehicle driver turns off the key signal, and the vehicle does not disconnect from the high-voltage power supply. Within a first preset time period (e.g., 120 seconds), the system checks whether the vehicle's battery swapping switch is activated. If the battery swapping switch is not activated within the first preset time period, the following steps are executed: Figure 4bThe process is as follows: If the battery swapping switch is turned on, the battery swapping procedure is executed, and high-voltage power is not applied for a second preset period (e.g., 120 seconds) after the battery swapping switch is turned off upon completion of the swap. If the key signal is received within the second preset period, the vehicle operates normally. If no key signal is received within the second period, the following procedure is executed: Figure 4c The process is shown below.

[0096] Please see Figure 4b ,like Figure 4b As shown, after the vehicle establishes communication with the battery swapping station, the vehicle does not disconnect from the high-voltage power supply after the driver turns off the key signal. If the battery swapping switch is not turned on but the key switch is turned on within the first time period, the vehicle will drive normally. If neither the battery swapping switch nor the key switch is turned on within the preset time period, the vehicle will disconnect from the high-voltage power supply and then from the low-voltage power supply in sequence. If the vehicle's battery swapping switch is turned on afterward, the vehicle will connect to the low-voltage power supply and then from the high-voltage power supply in sequence, and perform the battery swapping operation. If the vehicle's battery swapping switch is not turned on but the key switch is turned on, the vehicle will connect to the low-voltage power supply and then from the high-voltage power supply in sequence, and drive normally.

[0097] Please see Figure 4c ,like Figure 4c As shown, after the vehicle completes battery replacement and turns off the battery swapping switch, the vehicle is not disconnected from the high-voltage power supply. If a key signal is received within the preset second time period, the vehicle will drive normally. If no key signal is received within the preset second time period and the battery swapping is started, the vehicle will report an error. If a key signal is received after the second time period, the vehicle will drive normally. If the battery swapping switch is turned on after the second time period, the battery swapping operation will be performed.

[0100] In one alternative implementation, the third processing module 503 is specifically configured to control the power take-off to open the visor to a first designated position when the high voltage is on; in response to the visor being opened to the first designated position, to perform a high voltage power-off operation on the vehicle's battery management system (BMS); and in response to the completion of the high voltage power-off operation, to disconnect the constant power supply to the BMS and the wake-up signal path of the BMS.

[0101] Optionally, the third processing module 503 is specifically used for: restoring the constant power and wake-up signal path of the BMS; performing a high-voltage power-on operation on the BMS; controlling the power take-off to lower the brim to the second designated position under the high-voltage power-on state; and determining that the battery swapping completion operation has been completed in response to the brim falling to the second designated position.

[0102] In one implementation, the above apparatus further includes a fourth processing module. As an example, please refer to...

[0103] In an alternative implementation, the fourth processing module 604 is further configured to: start the vehicle in response to not receiving a battery swapping signal and receiving a start signal during the first time period.

[0105] The device described in this application embodiment can maintain the vehicle's high-voltage power supply for a period of time after receiving a handshake message from the battery swapping station and turning off the engine, thereby enabling immediate execution of the battery swapping operation upon receiving a battery swapping command.
