Technical Field

[0001] This invention belongs to the field of new energy vehicle technology, and in particular relates to a method, device, terminal equipment and storage medium for protecting vehicles from external discharge. Background Technology

[0002] With the rapid development of technology, the various functional modules of new energy vehicles are also being continuously optimized and improved.

[0003] Currently, new energy vehicles use inverters to convert the high-voltage DC power from the vehicle's power battery into 220VAC (Alternating Current) power for user output, in order to meet the user's multi-functional usage requirements. When users use various electrical devices in the vehicle, electrical safety is inevitably a concern. However, the existing methods of discharging the power battery into the external environment do not monitor or prevent electrical safety issues, so the existing methods of discharging the power battery into the external environment generally have low safety. Summary of the Invention

[0004] The main objective of this invention is to provide a method, device, terminal equipment, and storage medium for protecting vehicles from external discharge. The aim is to improve the safety of vehicles from external discharge.

[0005] To achieve the above objectives, the present invention provides a method for protecting a vehicle from external discharge. This method is applied to a vehicle, which includes a power strip and an inverter. The method includes:

[0006] After detecting that the switch of the discharge power strip is closed, the inverter is controlled to supply power to the discharge power strip, wherein the discharge power strip includes multiple sockets;

[0007] The power strip control unit in the discharge power strip detects whether multiple sockets have not output power for a preset time, and detects whether multiple sockets have all experienced a first preset abnormal condition.

[0008] If it is detected that multiple sockets have not output power for the preset time or that multiple sockets have experienced the first preset abnormal condition, then the power strip will be powered down for protection.

[0009] Optionally, the vehicle further includes a power management module and a power battery, and the step of controlling the inverter to supply power to the discharge plug includes:

[0010] The power supply request command is generated by the power strip control unit in the discharge power strip and sent to the power management module.

[0011] The power management module powers on the inverter based on the received power supply request command.

[0012] The inverter converts the DC power supplied by the power battery into AC power, and then supplies the AC power to the discharge socket.

[0013] Optionally, the step of generating a power supply request command through the power strip control unit in the discharge power strip and sending it to the power management module includes:

[0014] The power strip control unit in the discharge power strip detects whether multiple sockets have a second preset abnormal condition.

[0015] If none of the multiple sockets are found to be in the second preset abnormal condition, the power strip control unit generates a power supply request command and sends it to the power management module.

[0016] Optionally, before the step of powering on the inverter via the power management module based on the received power supply request command, the method further includes:

[0017] After the power management module receives the power supply request command, it checks whether the inverter has a third preset abnormal condition.

[0018] If the inverter does not exhibit the third preset abnormal condition, then the step of powering on the inverter by the power management module based on the received power supply request instruction is executed.

[0019] Optionally, after the step of detecting whether the plurality of sockets have a second preset abnormal condition, the method further includes:

[0020] If multiple sockets are detected to exhibit the second preset abnormal condition, it is determined that the discharge power strip has failed to draw power, and a socket self-test abnormality prompt is generated and output.

[0021] After the step of detecting whether the inverter has a third preset abnormal condition, the method further includes:

[0022] If the inverter is detected to have the third preset abnormal condition, it is determined that the discharge socket has failed to draw power, and an inverter self-test abnormality prompt is generated and output.

[0023] Optionally, the step of performing power-off protection on the discharge plug includes:

[0024] The power strip control unit generates an inverter power-off command and sends it to the power management module.

[0025] The power management module performs power-down processing on the inverter according to the inverter power-down command, and generates an inverter power-down completion command to send to the power strip control unit.

[0026] After the power strip control unit receives the power-down completion command of the inverter, it checks whether the power strip switch is open;

[0027] If the power strip switch is detected to be off, it is determined that the power-off of the discharge power strip is complete.

[0028] Optionally, after the step of detecting whether a first preset abnormal condition has occurred in the plurality of sockets through the circuit protection units corresponding to each of the plurality of sockets, the method further includes:

[0029] If it is detected that among the multiple sockets, there are sockets exhibiting the first preset abnormal condition and sockets that do not exhibit the first preset abnormal condition, then the sockets among the multiple sockets that do not exhibit the first preset abnormal condition are determined as target sockets, and a target socket abnormality prompt corresponding to the target socket is generated and output.

[0030] Furthermore, to achieve the above objectives, the present invention also provides a vehicle external discharge protection device, wherein the vehicle external discharge protection device is applied to a vehicle, the vehicle including a discharge power strip and an inverter, and the vehicle external discharge protection device includes:

[0031] A power supply module is used to control the inverter to supply power to the discharge socket after detecting that the socket switch of the discharge socket is closed, wherein the discharge socket includes multiple sockets;

[0032] The power strip detection module is used to detect, through the circuit protection units corresponding to the multiple sockets, whether the multiple sockets have not output power for a preset time, and whether the multiple sockets have all experienced a first preset abnormal condition.

[0033] The power strip power-off protection module is used to perform power-off protection processing on the discharge power strip if it is detected that multiple sockets have not output power for a preset time or multiple sockets have experienced the first preset abnormal condition.

[0034] In addition, to achieve the above objectives, the present invention also provides a terminal device, the terminal device comprising: a memory, a processor, and a vehicle external discharge protection program stored in the memory and executable on the processor, wherein when the vehicle external discharge protection program of the terminal device is executed by the processor, the steps of the vehicle external discharge protection method described above are implemented.

[0035] In addition, to achieve the above objectives, the present invention also provides a computer-readable storage medium storing a vehicle external discharge protection program, wherein when the vehicle external discharge protection program is executed by a processor, the steps of the vehicle external discharge protection method described above are implemented.

[0036] This invention monitors the working status of each socket on the discharge power strip after it is powered on in the vehicle. It also provides power-off protection for the discharge power strip when each socket has not output power for a preset time, and when each socket experiences a first preset abnormal condition. In other words, this invention automatically provides power-off protection for the discharge power strip when none of its sockets are connected to electrical equipment or when all sockets malfunction, thereby improving the safety of vehicle-to-the-world discharge.

The memory 1005 may be high-speed RAM or non-volatile memory, such as a disk drive. Optionally, the memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0049] Those skilled in the art will understand that Figure 1 The terminal device structure shown does not constitute a limitation on the terminal device and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0050] like Figure 1 As shown, the memory 1005, which serves as a computer storage medium, may include an operating system, a network communication module, a user interface module, and a protection program for vehicle external discharge.

[0051] exist Figure 1 In the terminal shown, network interface 1004 is mainly used to connect to the backend server and communicate data with it; user interface 1003 is mainly used to connect to the client and communicate data with it; and processor 1001 can be used to call the vehicle's external discharge protection program stored in memory 1005 and perform the following operations:

[0052] After detecting that the switch of the discharge power strip is closed, the inverter is controlled to supply power to the discharge power strip, wherein the discharge power strip includes multiple sockets;

[0053] The power strip control unit in the discharge power strip detects whether multiple sockets have not output power for a preset time, and detects whether multiple sockets have all experienced a first preset abnormal condition.

[0054] If it is detected that multiple sockets have not output power for the preset time or that multiple sockets have experienced the first preset abnormal condition, then the discharge power strip is powered down for protection. Furthermore, the vehicle also includes a power management module and a power battery, and the operation of controlling the inverter to supply power to the discharge power strip includes:

[0055] The power supply request command is generated by the power strip control unit in the discharge power strip and sent to the power management module.

[0056] The power management module powers on the inverter based on the received power supply request command.

[0057] The inverter converts the DC power supplied by the power battery into AC power, and then supplies the AC power to the discharge socket.

[0058] Furthermore, the operation of generating a power supply request command through the power strip control unit in the discharge power strip and sending it to the power management module includes:

[0059] The power strip control unit in the discharge power strip detects whether multiple sockets have a second preset abnormal condition.

[0060] If none of the multiple sockets are found to be in the second preset abnormal condition, the power strip control unit generates a power supply request command and sends it to the power management module.

[0061] Furthermore, before the step of powering on the inverter via the power management module based on the received power supply request command, the processor 1001 can also call the vehicle's external discharge protection program stored in the memory 1005 to perform the following operations:

[0062] After the power management module receives the power supply request command, it checks whether the inverter has a third preset abnormal condition.

[0063] If the inverter does not exhibit the third preset abnormal condition, then the step of powering on the inverter by the power management module based on the received power supply request instruction is executed.

[0064] Furthermore, after the step of detecting whether the multiple sockets have experienced a second preset abnormal condition, the processor 1001 can also call the vehicle's external discharge protection program stored in the memory 1005 to perform the following operations:

[0065] If multiple sockets are detected to exhibit the second preset abnormal condition, it is determined that the discharge power strip has failed to draw power, and a socket self-test abnormality prompt is generated and output.

[0066] After the step of detecting whether the inverter has a third preset abnormal condition, the processor 1001 can also call the vehicle external discharge protection program stored in the memory 1005 to perform the following operations:

[0067] If the inverter is detected to have the third preset abnormal condition, it is determined that the discharge socket has failed to draw power, and an inverter self-test abnormality prompt is generated and output.

[0068] Furthermore, the operation of performing power-down protection on the discharge plug includes:

[0069] The power strip control unit generates an inverter power-off command and sends it to the power management module.

[0070] The power management module performs power-down processing on the inverter according to the inverter power-down command, and generates an inverter power-down completion command to send to the power strip control unit.

[0071] After the power strip control unit receives the power-down completion command of the inverter, it checks whether the power strip switch is open;

[0072] If the power strip switch is detected to be off, it is determined that the power-off of the discharge power strip is complete.

[0073] Furthermore, after the step of detecting whether the multiple sockets have experienced a first preset abnormal condition through the circuit protection units corresponding to each of the multiple sockets, the processor 1001 can also call the vehicle external discharge protection program stored in the memory 1005 to perform the following operations:

[0074] If it is detected that among the multiple sockets, there are sockets exhibiting the first preset abnormal condition and sockets that do not exhibit the first preset abnormal condition, then the sockets among the multiple sockets that do not exhibit the first preset abnormal condition are determined as target sockets, and a target socket abnormality prompt corresponding to the target socket is generated and output.

[0075] Based on the above structure, various embodiments of the protection method for vehicle external discharge are proposed.

[0076] Please refer to Figure 2 , Figure 2This is a flowchart illustrating the first embodiment of the vehicle external discharge protection method of the present invention. It should be noted that although the logical order is shown in the flowchart, in some cases, the vehicle external discharge protection method of the present invention may execute the steps shown or described in a different order. In this embodiment, the executing entity of the vehicle external discharge protection method can be a new energy vehicle, a personal computer, a smartphone, or other devices. This embodiment does not impose any limitations, and for ease of description, the executing entity is omitted from the description of each embodiment. In this embodiment, the vehicle external discharge protection method is applied to a vehicle, which includes a discharge power strip, an inverter, a power management module, and a power battery. The vehicle external discharge protection method includes:

[0077] Step S10: After detecting that the switch of the discharge power strip is closed, control the inverter to supply power to the discharge power strip, wherein the discharge power strip includes multiple sockets;

[0078] When the switch of the discharge power strip in the vehicle is detected to be closed, the inverter in the vehicle is controlled to generate electrical energy to power the discharge power strip, which includes multiple sockets.

[0079] It should be noted that, as Figure 3 As shown, the power battery includes multiple relays and a BMS (Battery Management System), and the discharge power strip includes a power strip control unit, a power strip switch K1, three sockets, and corresponding protection devices for each of the three sockets. It should be understood that in different embodiments, the number of sockets on the discharge power strip can be any number that meets actual needs; this invention does not limit the number of sockets.

[0080] In one feasible implementation, when the vehicle is in the start position, insulation and relay adhesion tests are performed on the vehicle's power battery. When both insulation and relay adhesion tests pass normally, the BMS system closes the relevant relays to initiate the vehicle power-on process. After the vehicle is powered on, a "vehicle power-on complete command" is sent to the discharge plug control unit via the CAN (Controller Area Network) bus. Then, the discharge plug control unit, which is in standby mode, detects whether the plug switch is pressed and controls the inverter to supply power to the discharge plug when the plug switch is pressed.

[0081] It needs to be clarified that, for example Figure 3 As shown, the DC (Direct Current) / AC (Alternating Current) module is the inverter mentioned above.

[0082] Step S20: The power strip control unit in the discharge power strip detects whether the multiple sockets have not output power for a preset time, and detects whether the multiple sockets have all experienced a first preset abnormal condition.

[0083] The power strip control unit in the power strip detects whether multiple sockets have not output power for a preset time, and whether multiple sockets have experienced a first preset abnormal condition.

[0084] It should be noted that the aforementioned first preset abnormal condition may include, but is not limited to, the failure of the protection device corresponding to the socket, 220VAC output overvoltage, 220VAC output overcurrent, 220VAC output undervoltage, circuit overheating, water immersion and damage, etc.

[0085] In one feasible implementation, after the inverter supplies power to the discharge power strip, and the discharge power strip is in an operational state, the power strip control unit detects the operational status of each socket and receives data such as... Figure 3 The signal fed back by the protection device shown.

[0086] In another feasible implementation, after the inverter supplies power to the discharge power strip, and the discharge power strip is in working condition, the power strip control unit of the discharge power strip will detect whether each socket has a first abnormal condition.

[0087] Furthermore, in a feasible embodiment, after step S20 above, the method for protecting a vehicle from external discharge according to the present invention further includes:

[0088] Step A10: If it is detected that there are sockets with the first preset abnormal condition and sockets without the first preset abnormal condition among the multiple sockets, then the sockets without the first preset abnormal condition among the multiple sockets are determined as target sockets, and a target socket abnormality prompt corresponding to the target socket is generated and output.

[0089] When multiple sockets are found to be abnormal, and at least one socket is abnormal, the abnormal socket is identified (hereinafter referred to as the target socket for distinction), and then an abnormal prompt corresponding to the target socket is generated and output.

[0090] In one feasible implementation, the power strip control unit of the discharge power strip performs abnormal detection on the three sockets respectively, and determines that the above-mentioned first preset abnormal condition does not occur in all three sockets, and at least one socket has the above-mentioned first preset abnormal condition. Then, the target socket with abnormality is identified, and an abnormality prompt is generated according to the discharge circuit where the target socket is located. The abnormality prompt is displayed on the instrument display screen to remind the user that the target socket has abnormality and needs manual inspection or repair.

[0091] Step S30: If it is detected that multiple sockets have not output power for the preset time or multiple sockets have the first preset abnormal condition, then power-off protection processing is performed on the discharge power strip.

[0092] If multiple sockets of the discharge power strip fail to output power for a preset time, or if multiple sockets exhibit a first preset abnormal condition, the power strip will be powered down for protection.

[0093] In one feasible implementation, when it is detected that there is no load power output in each socket for a preset time of 10 minutes, the power strip is powered off for protection.

[0094] In another feasible implementation, when a first preset abnormal condition is detected in each socket, the power strip is powered down for protection.

[0095] Furthermore, in step S30 above, the step of "performing power-down protection processing on the discharge plug" includes:

[0096] Step S301: The power strip control unit generates an inverter power-down command and sends it to the power management module;

[0097] After determining that power-down protection is required for the discharge power strip, the power strip control unit in the discharge power strip generates an inverter power-down command and sends the inverter power-down command to the power management module.

[0098] In one feasible implementation, after detecting the operating status of multiple sockets on the discharge power strip and determining that power-down protection of the discharge power strip is required, the power strip control unit of the discharge power strip generates a command to shut down the 220VAC power supply, namely the aforementioned inverter power-down command, and sends the inverter power-down command to the ODP (On-board Power Management) control unit via the CAN bus.

[0099] Step S302: The power management module performs power-down processing on the inverter according to the inverter power-down command, and generates an inverter power-down completion command and sends it to the power strip control unit.

[0100] The power management module powers down the inverter according to the inverter power-down command generated by the power strip control unit, generates an inverter power-down completion command, and then sends the inverter power-down completion command to the power strip control unit.

[0101] In one feasible implementation, the power strip control unit sends an inverter power-down command to the ODP control unit via the CAN bus. After receiving the inverter power-down command, the ODP control unit performs power-down processing on the DC / AC module, generates a "DC / AC power-down completion command", and sends the "DC / AC power-down completion command" to the power strip control unit via the CAN bus.

[0102] Step S303: After the power strip control unit receives the power-down completion command of the inverter, it checks whether the power strip switch is open.

[0103] After receiving the power-down command from the inverter, the power strip control unit checks whether the power strip switch of the discharge power strip is open.

[0104] In one feasible implementation, the power strip control unit detects whether the power strip switch K1 is open.

[0105] Step S304: If the power strip switch is detected to be off, it is determined that the power-off of the discharge power strip is complete.

[0106] When the power strip switch is detected to be off, it is determined that the power strip has been de-energized.

[0107] In one feasible implementation, such as Figure 5 As shown, when the 220VAC discharge power strip is in operation, the system detects its operation status and enters a "whether to continuously output load power" judgment process. If the detection is "yes," the operation status detection process continues; if the detection is "no," a delay control process is entered and continues for 10 minutes. The system then checks whether the delay status "has accumulated for 10 minutes." If the detection is "no," the operation status detection process continues; if the detection is "yes," a "220VAC shutdown request command" is sent to the ODP control unit. The ODP control unit checks the "220VAC shutdown request command." If the detection is "no," the operation status remains; if the detection is... If the result is "Yes", the DC / AC shutdown control process is initiated, and a power-down command is executed. Once the DC / AC power-down is complete, a command is sent to the CAN bus. The 220VAC discharge power strip detects the "DC / AP power-down complete" command. If the detection is "No", a "220VAC shutdown request command" command is sent to the ODP control unit. If the detection is "Yes", the 220VAC discharge power strip enters the "Unlock K1 switch?" process. If the detection is "No", a "K1 switch not unlocked command" is sent to the CAN bus, reminding the user to "operate the K1 switch, otherwise it will affect the next power supply", and the user unlocks the K1 switch. If the detection is "Yes", the power-down is complete.

[0108] In another feasible implementation, such as Figure 6As shown, when the 220VAC discharge power strip is in operation, the system checks its status and enters a "whether a socket abnormality is detected" judgment process. If the detection is "no", the system continues the status detection process. If the detection is "yes", the system enters the "whether all 3 sockets are abnormal" judgment process. If the detection is "no", the system checks "whether at least 1 socket is abnormal". If the detection is "yes", the system sends abnormal discharge circuit information to the CAN bus and displays the fault circuit information on the instrument panel. If the detection is "yes", the system sends a "220VAC shutdown request command" to the ODP control unit. The ODP control unit checks the "220VAC shutdown request command". If the detection is... If the result is "No", the device remains in operation. If the result is "Yes", it enters the DC / AC shutdown control process and executes the power-down command. After the DC / AC power-down is completed, it sends a command to the CAN bus. The 220VAC discharge power strip checks the "DC / AP power-down complete" command. If the result is "No", it sends a "220VAC shutdown request command" command to the ODP. If the result is "Yes", the 220VAC discharge power strip enters the "Unlock K1 switch?" process. If the result is "No", it sends a "K1 switch not unlocked command" command to the CAN bus and reminds the user to "operate the K1 switch, otherwise it will affect the next power supply". The user then unlocks the K1 switch. If the result is "Yes", the power-down is complete.

[0109] In this embodiment, the vehicle external discharge protection method of the present invention is applied to a vehicle, which includes a discharge power strip and an inverter. The present invention controls the inverter in the vehicle to generate electrical energy to power the discharge power strip when the power strip switch in the discharge power strip is detected to be closed. The discharge power strip includes multiple sockets. The power strip control unit in the discharge power strip detects whether all multiple sockets have not output power for a preset time, and whether all multiple sockets have experienced a first preset abnormal condition. When multiple sockets are not all abnormal, and at least one socket is abnormal, the target socket with the abnormality is determined, and then an abnormality prompt corresponding to the target socket is generated and output. The method detects the abnormality of multiple sockets in the discharge power strip. If no power output is performed for a preset time, or if multiple sockets experience a first preset abnormal condition, the discharge power strip will be powered down for protection. After determining that power-down protection is necessary, the power strip control unit generates an inverter power-down command and sends it to the power management module. The power management module then powers down the inverter according to the command and generates a power-down completion command, which is sent to the power strip control unit. Upon receiving the power-down completion command, the power strip control unit checks if the power strip switch is open. If the switch is open, the power strip power-down is considered complete.

[0110] Thus, this embodiment of the invention monitors the working status of each socket on the discharge power strip after it is powered on in the vehicle, and provides power-off protection for the discharge power strip when it is detected that each socket has not output power for a preset time, and also provides power-off protection for the discharge power strip when it is detected that each socket has a first preset abnormal condition. In other words, this embodiment of the invention realizes automatic power-off protection for the discharge power strip when none of the sockets on the discharge power strip are connected to electrical equipment or when all the sockets are abnormal, thereby improving the safety of vehicle external discharge.

[0111] Furthermore, based on the first embodiment of the vehicle external discharge protection method of the present invention described above, a second embodiment of the vehicle external discharge protection method of the present invention is proposed.

[0112] In this embodiment, step S10 includes:

[0113] Step S101: The power supply request command is generated by the power strip control unit in the discharge power strip and sent to the power management module;

[0114] When the power strip switch of the discharge power strip is detected to be closed, a power supply request command is generated by the power strip control unit in the discharge power strip and sent to the power management module.

[0115] In one feasible implementation, such as Figure 3 As shown, the ODP module, i.e. the power management module mentioned above, includes a DC / AC module (i.e. the inverter mentioned above) and an ODP control unit. The ODP control unit is connected to the plug control unit of the discharge plug. When the plug control unit detects that the plug switch of the discharge plug is closed, the plug control unit generates a power supply request command and sends the power supply request command to the ODP control unit through the CAN bus.

[0116] Furthermore, in a feasible embodiment, step S101 above includes:

[0117] Step B10: The power strip control unit in the discharge power strip detects whether a second preset abnormal condition has occurred in each of the multiple sockets.

[0118] When the power strip switch of the discharge power strip is detected to be closed, the power strip control unit on the discharge power strip checks whether a second preset abnormal condition has occurred in multiple sockets.

[0119] It should be noted that the aforementioned second preset abnormal conditions include, but are not limited to, insulation abnormalities, withstand voltage abnormalities, and protection device failures, etc.

[0120] In one feasible implementation, when the discharge power strip in standby mode detects that the power strip switch is closed, the three sockets on the discharge power strip are first subjected to an abnormal self-test by the power strip control unit.

[0121] Furthermore, in one feasible embodiment, after step B10 above, the method further includes:

[0122] Step C10: If multiple sockets are detected to have the second preset abnormal condition, it is determined that the discharge power strip has failed to draw power, and a socket self-test abnormality prompt is generated and output.

[0123] If multiple sockets are detected to have the second preset abnormal condition, it is determined that the power strip failed to draw power, and a socket self-test abnormality prompt is generated and output.

[0124] In one feasible implementation, when a second preset abnormal condition is detected in at least one of the three sockets, it is determined that the power strip has failed to draw power, and a socket self-test abnormality prompt is generated and displayed on the vehicle's instrument panel display.

[0125] Step B20: If none of the multiple sockets are found to be in the second preset abnormal condition, a power supply request command is generated by the discharge power strip and sent to the power management module.

[0126] When it is detected that none of the sockets on the power strip have the second preset abnormal condition, a power supply request is generated by the power strip control unit and sent to the power management module.

[0127] Step S102: The power management module powers on the inverter based on the received power supply request command.

[0128] When the power management module receives a power supply request command from the discharge connector, it powers on the inverter.

[0129] In one feasible implementation, the ODP control unit powers on the DC / AC module based on the power supply request command from the discharge power strip and generates a "DC / AC power-on completion command". This "DC / AC power-on completion command" is sent to the power strip control unit via the CAN bus to complete the power supply to the discharge power strip and detect the socket's working status.

[0130] Furthermore, in one feasible embodiment, prior to step S102 above, the following step is also included:

[0131] Step D10: After the power management module receives the power supply request instruction, it checks whether the inverter has a third preset abnormal condition.

[0132] When the power management module receives a power supply request command from the discharge socket, it performs anomaly detection on the inverter to check whether the inverter has a third preset abnormal condition.

[0133] It should be noted that the aforementioned third preset abnormal conditions include, but are not limited to, insulation abnormalities, input voltage abnormalities, communication abnormalities, high-voltage interlocking abnormalities, etc.

[0134] Furthermore, in one feasible embodiment, after step D10 described above, the method further includes:

[0135] Step C20: If the inverter is detected to have the third preset abnormal condition, it is determined that the discharge plug has failed to draw power, and an inverter self-test abnormality prompt is generated and output.

[0136] When an inverter malfunction is detected, it is determined that the power supply to the discharge port has failed, and an inverter self-test malfunction prompt is generated and displayed on the vehicle's instrument panel display.

[0137] Step D20: If the inverter does not exhibit the third preset abnormal condition, then the step of powering on the inverter by the power management module based on the received power supply request instruction is executed.

[0138] When the power management module detects that the inverter has not experienced the third preset abnormal condition, it powers on the inverter based on the received power supply request command.

[0139] In one feasible implementation, such as Figure 4As shown, when the vehicle is in the ON position, the vehicle performs a "vehicle insulation test" to determine if it is normal. If the test is "no", power-on fails and a fault message is reported. If the test is "yes", the vehicle enters the relay adhesion test process. The "relay adhesion test" process is then performed. If the test is "no", power-on fails and a fault message is reported. If the test is "yes", the vehicle enters the battery high-voltage power-on process. A "power battery power-on complete" test is then performed. If the test is "no", power-on fails and a fault message is reported. If the test is "yes", a power battery power-on complete command is sent to the CAN bus. The 220VAC discharge connector checks the power battery power-on complete status and remains in standby mode. It checks if the "K1 switch is pressed". If the test is "no", it remains in standby mode. If the test is "yes", it enters the self-test process. Finally, a "self-test for abnormalities" process is performed. If the test is "yes", the test is completed. If the 220VAC power supply fails and a fault message is reported, and the detection is "No", a "220VAC power supply request" command is sent. The ODP control unit performs a power battery power-on completion status check and is in standby mode. It checks the "220VAC power supply request" command. If the detection is "No", it remains in standby mode. If the detection is "Yes", it enters the self-test process. It performs a "self-test for abnormality" process. If the detection is "Yes", the 220VAC power supply fails and a fault message is reported. If the detection is "No", the DC / AC power-on is completed and a "DC / AC power-on complete" command is sent. The 220VAC discharge power strip checks the "DC / AC power-on complete" command. If the detection is "No", it sends a "220VAC power supply request" command to the ODP control unit. If the detection is "Yes", the 220VAC socket power supply is completed and it enters the working status check.

[0140] Step S103: The inverter converts the DC power supplied by the power battery into AC power and supplies the AC power to the discharge plug.

[0141] The inverter converts the DC power supplied by the power battery connected to the inverter into AC power, and then supplies the AC power to the discharge outlet.

[0142] In one feasible implementation, the vehicle's power battery is used as the sole power source to provide high-voltage direct current to the inverter. The inverter converts the high-voltage direct current into 220V alternating current, and then a 220VAC power outlet is provided to the user to provide a 220VAC power supply interface.

[0143] It should be noted that, as Figure 3 As shown, the vehicle components involved in this invention include a power battery, an ODP module, and a discharge power strip. The power battery provides high-voltage DC power to the vehicle; the ODP module provides power distribution and power inversion for the vehicle; and the discharge power strip provides a 220VAC power input interface for the user and also provides safety protection for the power input circuit.

[0144] In this embodiment, the vehicle external discharge protection method of the present invention, when detecting the closure of the discharge socket switch, generates a power supply request command through the socket control unit in the discharge socket and sends the power supply request command to the power management module; when detecting the closure of the discharge socket switch, the socket control unit on the discharge socket checks whether multiple sockets have experienced a second preset abnormal condition; if multiple sockets have experienced the second preset abnormal condition, it is determined that the discharge socket has failed to draw power, and a socket self-test abnormality prompt is generated and output; when it is detected that none of the sockets on the discharge socket have experienced the second preset abnormal condition, the socket control unit generates a power supply request and sends the power supply request to the power management module; through When the power management module receives a power supply request command from the discharge plug, it powers on the inverter. Upon receiving the same command, it performs anomaly detection on the inverter to check for a third preset anomaly. If an anomaly is detected, it determines that the discharge plug has failed to draw power and generates an inverter self-test anomaly message, which is displayed on the vehicle's instrument panel. If the power management module detects that the inverter does not exhibit the third preset anomaly, it powers on the inverter based on the received power supply request command. The inverter then converts the DC power supplied by the connected power battery into AC power and supplies the AC power to the discharge plug.

[0145] Thus, the present invention ensures the high-voltage safety of the entire vehicle by detecting the discharge circuit through the protection device of the discharge plug and by using the CAN network to realize information exchange between various components.
