[0039] The embodiments of this application are described below with reference to the accompanying drawings. The terminology used in the implementation section of this application is for explaining specific embodiments only and is not intended to limit the scope of this application.

[0040] The embodiments of this application will now be described with reference to the accompanying drawings. Those skilled in the art will recognize that, with technological advancements and the emergence of new scenarios, the technical solutions provided in the embodiments of this application are equally applicable to similar technical problems.

It should be understood that such terms are interchangeable where appropriate; this is merely a way of distinguishing objects with the same attributes in the embodiments of this application.

[0042] See Figure 1 , Figure 1 This is a flowchart illustrating a safety control method for a battery swapping station provided in an embodiment of this application. Figure 1 As shown in the embodiment of this application, a safety control method for a battery swapping station is provided, which can be applied to a battery swapping PLC (Programmable Logic Controller). The safety control method for a battery swapping station may include steps S10 to S30, which are described in detail below.

[0043] S10, Identify the target equipment to be operated from the equipment within the station.

[0044] The equipment within a battery swapping station typically includes vehicle positioning equipment, battery removal equipment, and battery transport equipment. These three automated devices enable the battery swapping function. The vehicle positioning equipment positions the vehicle entering the station, usually clamping the wheels to center them. Once positioned, the relative position of the low-charged battery pack on the vehicle and the battery removal equipment is determined. The battery removal equipment then removes the low-charged battery pack, and the battery transport equipment transports it to the station for charging. Simultaneously, the battery transport equipment retrieves a fully charged battery pack from the station and hands it over to the battery removal equipment, which then reinstalls the fully charged battery pack onto the vehicle. The vehicle positioning equipment then de-positions the vehicle, completing the entire battery swapping process.

[0045] Therefore, when an automated task (such as a battery swapping task) is executed, the battery swapping PLC responds to the automated task and determines the target device among the station's equipment based on the battery swapping process. For example, after the battery removal equipment removes the undercharged battery pack, the target device to be activated is the battery handling equipment.

[0046] S20: Collect the preliminary information of the target device. The preliminary information is collected through a closed-loop judgment method using deployed sensors or state memory functions.

[0047] In this embodiment, before the target device performs the corresponding target action, it is necessary to collect its preliminary information, which is the relevant information of the target device's execution environment. For ease of understanding, let's continue with the example of a battery handling device. When the battery handling device moves a fully charged battery pack, it needs to ensure that the battery handling device moves to the designated position and that the connector inside the compartment of the fully charged battery pack is disconnected. However, when the battery pack is in a monitored state inside the compartment, it remains connected to the connector inside the compartment. At this time, the battery handling device cannot move the battery, so it is necessary to disconnect the connector inside the compartment before the battery handling device can perform the handling action.

[0048] In this embodiment, prior information about the battery handling equipment is collected. This prior information includes the location information of the battery handling equipment, the status of the fully charged battery pack to be handled, and the status of the connectors inside the compartment. To ensure the effectiveness of the prior information collection, this embodiment uses a closed-loop method with secondary judgment based on the deployment of sensors or state memory functions to collect the prior information.

[0049] Specifically, battery handling equipment typically uses servo motors for driving and transmission devices to achieve movement. If the transmission device fails, even if the servo motor has reached the designated position, the battery handling equipment may not actually have moved to that position. Therefore, adding a sensor at the designated position for secondary judgment can significantly reduce the possibility of a single judgment failure. In other words, when collecting the position information of the battery handling equipment, both the actual motor position of the servo motor and the sensor readings at the designated position are collected. Only when the actual motor position matches the designated position and the sensor readings are not empty does it indicate that the battery handling equipment has moved to the designated position.

[0050] Furthermore, the battery handling equipment carries undercharged batteries before moving a fully charged battery pack. Therefore, if the equipment moves to a designated location carrying undercharged batteries to move a fully charged battery, a battery collision could occur. To address this, the battery handling equipment needs to determine whether it carries undercharged batteries before moving a fully charged battery. This can only be determined by a position sensor, and if the position sensor fails, there is no other way to determine this. To solve this, this application adds a state memory function for secondary determination. Specifically, it adds a variable for the battery pack's position status. The battery handling equipment updates the battery pack's position status after each step of the operation without any abnormalities. For example, if the battery handling equipment successfully completed the movement of the undercharged battery pack last time, the corresponding battery pack's position status will be "battery present" to prevent a failure of the position sensor from causing a situation where a battery should be present to be judged as "battery absent." In other words, when collecting the status of the fully charged battery pack of the battery handling equipment connected to the compartment, the system collects both the battery pack's position status and the connection status between the fully charged battery pack and the compartment. Only when the battery pack's position status is "with battery" and the connection status between the fully charged battery pack and the compartment is "disconnected" does it indicate that the fully charged battery pack is disconnected from the connector inside the compartment.

[0051] S30: If the preceding information satisfies the preceding state of the target device, control the target device to execute the corresponding target action and monitor whether the target device has timed out.

[0052] In this embodiment of the application, for ease of understanding, the battery handling device is taken as an example. When the actual motor position of the servo motor is the specified motor position, the sensor sensing information at the specified position is not empty, the battery pack corresponding to the fully charged battery pack is in the battery state, and the fully charged battery pack is disconnected from the compartment, it is determined that the battery handling device meets the corresponding preconditions. At this time, the control is to execute the handling action of the fully charged battery pack by the battery handling device.

[0053] In addition, since the battery handling equipment requires a certain level of vision to perform the handling action, it can be judged after the maximum execution time of the handling action has been exceeded when determining whether the battery handling equipment has moved the battery to the correct position. If the battery handling equipment has not completed the handling action of the fully charged battery pack, an overtime failure fault can be reported.

[0054] In one possible implementation, due to the large number of devices within a battery swapping station, if one device malfunctions, all devices within the station stop working, causing even the non-malfunctioning devices to switch from an active state to a suspended state. To address this, an embodiment of this application provides a battery swapping station safety control method that further includes the following steps:

[0055] In response to a report of a fault in a device other than the current one, a pause command is sent to the target device to cause the target device to suspend the execution of the target action; the first operating state of the target device when it suspends the execution of the target action is recorded; in response to a repair operation of a fault in a device other than the current one, the current second operating state of the target device is obtained, and if the second operating state is the same as the first operating state, a continue command is sent to the target device to cause the target device to continue the execution of the target action.

[0056] In this embodiment of the application, if a fault other than the current device is reported for the target device, a pause command is sent to the target device in response to the reporting operation of the fault other than the current device, so that the target device suspends the execution of its target action, and the running state of the target device when suspending the execution of the target action (i.e., the first running state) is recorded. Taking the battery handling device as an example, if the battery handling device pauses when handling a fully charged battery pack, the current movement position of the battery handling device and whether the fully charged battery has been taken out are recorded.

[0057] After the fault of the non-current device is repaired, respond to the repair operation of the non-current device and obtain the current operating status of the target device (i.e., the second operating status). Compare the first operating status with the second operating status. If the two are the same, it means that the target device is in the state when the fault of the non-current device triggered the pause. At this time, a continue command can be issued to the target device to enable the target device to continue to execute the target action.

[0058] In one possible implementation, since the secondary judgment closed-loop method often uses sensor judgment, taking the battery handling equipment as an example, the possibility of sensor failure at the designated position is usually greater than that of transmission device failure. If the sensor failure causes the battery handling equipment to be determined not to have moved to the designated position, the sensor can be disabled after the battery handling equipment has moved to the designated position by manual judgment, and the subsequent tasks can continue to be executed. After being disabled, only the current task can be executed. At this time, the manual judgment is used as a secondary judgment, which ensures battery swapping efficiency under relatively safe conditions.

[0059] In practical applications, when a sensor used for secondary closed-loop judgment is shielded, the shielding method is usually to report a virtual signal to meet the conditions. However, the virtual signal may cause other programs to make incorrect judgments, thus causing unknown security problems. Therefore, the embodiments of this application adopt the method of shielding judgment conditions when shielding; that is, after shielding, no secondary judgment is performed, instead of reporting a virtual signal to meet the secondary judgment.

[0060] In the scenario described above where the sensor is shielded, in order to prevent the target device from performing the next task, the battery swapping PLC needs to perform a comprehensive self-check after each task is completed to check for any fault reports and whether the shielding state has been activated.

[0061] In one possible implementation, to achieve proactive safety protection against thermal runaway of battery packs within the station, this embodiment of the application can proactively execute a handling task upon detecting thermal runaway of the battery pack, moving the thermally runaway battery pack to a safe area to prevent the situation from escalating. See also... Figure 2 , Figure 2 This is a partial flowchart illustrating a safety control method for a battery swapping station provided in an embodiment of this application. Figure 2 As shown in the embodiment of this application, a safety control method for a battery swapping station is provided. Step S10, "determining the target device to be operated from the equipment in the station", may include steps S101 to S102. These steps are described in detail below.

[0062] S101 receives the fire escape command issued by the main control system. The fire escape command is issued by the main control system after receiving the thermal runaway warning from the battery monitoring system.

[0063] In this embodiment, the battery monitoring system and the BMS (Battery Management System) maintain constant communication. When thermal runaway occurs in the battery pack, the BMS sends a thermal runaway warning to the battery monitoring system, which then reports the warning to the main control system. The main control system sends a fire-fighting evacuation command to the battery swapping PLC for the thermal runaway battery pack. The battery swapping PLC responds to the command by targeting the battery handling equipment and sends a handling command to the equipment for the thermal runaway battery pack. The battery handling equipment then moves the thermal runaway battery pack to an isolation area.

[0064] When the battery swapping station is in service, i.e. the battery handling equipment is working, the battery swapping PLC will prioritize the fire-fighting exit task after receiving the fire exit command. It will control the battery handling equipment to place the battery pack being transported to the nearest position and continue to carry out the transport of the thermal runaway battery pack. Of course, it will also pause the operation of other equipment. After the thermal runaway battery pack is transported to the isolation area, it will resume controlling the operation of the battery handling equipment and other equipment.

[0065] S102, when the battery compartment door is closed, responds to the fire exit command and uses the battery handling equipment as the target equipment.

[0066] In this embodiment, when operators are performing maintenance inside the battery compartment, to avoid safety issues, the battery swapping PLC checks the status of the battery compartment door after receiving a fire evacuation command. If the battery compartment door is open, the fire evacuation task is not executed; the task continues only after the operators have evacuated and closed the battery compartment door. If the battery compartment door is closed, the fire evacuation command is responded to by designating the battery handling equipment as the target device and issuing a handling command for the thermal runaway battery pack to the battery handling equipment, which then moves the thermal runaway battery pack to the isolation area.

[0067] In one possible implementation, to achieve passive protection for safe manual operation, this application provides a battery swapping station safety control method, wherein step S10, "determining the target equipment to be operated from the equipment within the station," can be performed using the following steps:

[0068] In response to the first click operation, the device indicated by the first click operation in the station's devices will be used as the target device.

[0069] In this embodiment, the actions of the equipment within the station can be manually operated. The battery swapping PLC can use the device indicated by the first click as the target device. When manually clicking the button to instruct the target device to perform the target action, it should be manually determined whether the preconditions for the target action are met, i.e., whether structural interference will occur after the action is performed. For example, if the battery handling equipment is a palletizer structure (capable of walking and lifting, including retractable forks for lifting batteries), clicking "extend forks" might cause the forks to collide with the battery storage rack if the battery handling equipment is located in a corresponding position in a battery compartment, leading to a safety issue. Therefore, if the preconditions for the target action are not met, an alarm should be triggered to remind the operator of the unmet conditions, thus guiding the operator.

[0070] Based on this, if the target action cannot be executed after manual clicking due to unmet prerequisites, the battery swapping PLC will not automatically execute the target action. When the prerequisites are satisfied again, manual clicking is required again to execute the target action. Therefore, the battery swapping station safety control method provided in this application embodiment may further include the following steps:

[0071] If the prerequisite information does not meet the prerequisite state corresponding to the target device, respond to the second click operation for the target device and return to the execution step S20.

[0072] In this embodiment, after the first click operation, the battery-swapping PLC collects the prerequisite information and determines that the prerequisite information does not meet the prerequisite state corresponding to the target device. Then, it waits for manual verification to determine whether the prerequisite state for executing the target action is met again. For example, if a person clicks the lifting button on a device and finds that the sensor position has shifted, resulting in the prerequisite state not being met, and then the person stands on the device to adjust the sensor position, and all conditions are met after the adjustment, the device will lift or lower, which could lead to a safety risk for the person. Therefore, after manual verification that the prerequisite state is met, the button instructing the target device to execute the target action needs to be clicked again. The battery-swapping PLC continues to execute step S20, collecting the prerequisite information, and when the prerequisite information meets the corresponding prerequisite state, it controls the target device to execute the target action.

[0073] In practical applications, if a button contains a composite action of multiple devices within the station, taking two devices A and B as an example, after a person presses the button, if the prerequisite state of device A has been met, but the prerequisite state of device B has not been met, then neither device A nor device B will execute their respective actions.

[0074] To achieve protection during maintenance operations, if personnel need to jog (i.e., control the axis to rotate in a certain direction after clicking a button) the position of the servo motor shaft fine adjustment device during maintenance, the positive and negative soft limit positions of the motor should be set in advance. If the motor rotates beyond the soft limit position during the jogging operation, it will stop immediately and trigger an alarm.

[0075] In addition, the embodiments of this application use HMI human-computer interaction interface buttons, which transmit the button click operation after a click delay to prevent accidental touches by personnel.

[0076] In one possible implementation, to achieve preventative safety protection for the battery pack, an embodiment of this application provides a battery swapping station safety control method, which further includes the following steps:

[0077] Acquire scanned images of the target battery pack and perform state detection on the target battery pack based on the scanned images.

[0078] In this embodiment, the target battery pack is the battery pack to be protected against preventative safety measures. The status detection of the target battery pack may include battery flaw detection and locking structure anomaly detection.

[0079] For battery flaw detection, the bottom of the target battery pack can be scanned to obtain a bottom scan image. Based on image processing and image recognition technology, the bottom scan image can be detected to determine whether there are any suspected scratches on the bottom of the target battery pack.

[0080] For detecting abnormalities in the locking structure, the top of the target battery pack can be scanned to obtain a top scan image. Based on image processing and image recognition technologies, the top scan image can be used to detect whether the top locking structure of the target battery pack is abnormal.

[0081] In one possible implementation, to achieve preventative safety protection for equipment within the station, an embodiment of this application provides a battery swapping station safety control method, which further includes the following steps:

[0082] Collect torque data from equipment within the station and perform status monitoring on the equipment based on the torque data; and / or

[0083] Collect the usage count of key structural components of the equipment within the station, and conduct durability tests on the key structural components based on the usage count.

[0084] In this embodiment, since the on-site equipment such as the vehicle positioning device, battery removal device, and battery handling device all involve certain physical movements (translation and rotation), the power source for these movements is a servo motor drive. The servo motor can provide feedback on key motor information (such as time, motor shaft torque, speed, and displacement) when driving the load. For example, in the battery removal device, a tightening gun used to tighten and loosen the locking mechanism on the battery pack records data during tightening and loosening. By recording a large amount of experimental data (key data such as torque and speed of the servo motor corresponding to the tightening gun during normal tightening and loosening) and then performing statistical analysis, the system torque curve of the motor torque that the motor should meet during normal tightening can be obtained as a function of time.

[0085] For each actual battery swap, the torque data of the tightening gun is compared with the torque curve of the system to determine whether the tightening process is normal. If the torque data of the tightening gun differs significantly from the characteristics of the system torque curve and exceeds a threshold, the tightening process is considered abnormal. This leads to further investigation into whether there is an abnormality in the tightening gun, the battery removal equipment, or the battery pack, and maintenance recommendations are then generated.

[0086] In addition, for critical structural components of the equipment in the station, such as lead screws, slide rails, couplings, bearings, reducers, electric push rods, positioning pins, and battery pack locking mechanisms, durability tests can be conducted by checking their number of uses. Referencing the maximum number of uses given by the manufacturer, an alarm will be triggered when the maximum number of uses is about to be reached, prompting maintenance personnel to perform preventative maintenance.

[0087] Based on the above description, the battery swapping station safety control method provided in this application provides passive safety protection against safety hazards that may exist when the automated equipment in the station operates, active safety protection against thermal runaway of the battery pack in the station, and preventive safety protection against equipment maintenance and battery maintenance in the station. The combination of passive, active and preventive protection methods can significantly improve the safety of the battery swapping station.

[0088] The above describes a method for safety control of a battery swapping station provided by an embodiment of this application. The following describes the apparatus for implementing the above-described method for safety control of a battery swapping station.

[0089] See Figure 3 , Figure 3 This is a schematic diagram of a safety control device for a battery swapping station provided in an embodiment of this application.

[0090] The equipment determination module 10 is used to determine the target equipment to be operated from the equipment in the station;

[0091] The safety control module 20 is used to collect the prior information of the target device.

When the prior information meets the corresponding prior state of the target device, the module controls the target device to perform the corresponding target action and monitors whether the target device has timed out.

[0092] In one possible implementation, the security control module 20 is also used for:

[0093] In response to a report of a fault in a device other than the current one, a pause command is sent to the target device to cause the target device to suspend the execution of the target action; the first operating state of the target device when it suspends the execution of the target action is recorded; in response to a repair operation of a fault in a device other than the current one, the current second operating state of the target device is obtained, and if the second operating state is the same as the first operating state, a continue command is sent to the target device to cause the target device to continue the execution of the target action.
