[0029] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0030] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0031] Before introducing the specific embodiments, the application scenarios of the control method of the battery locking mechanism of the present invention are first introduced. Figure 1As shown, the battery locking mechanism refers to a mechanism for fixing the vehicle battery pack, which is set in the vehicle, wherein the vehicle type may include but is not limited to trucks, commercial vehicles, etc.; the battery locking mechanism is electrically connected to the vehicle terminal, and the vehicle terminal is connected to the battery swap station terminal in communication. After the battery swap station terminal detects that the vehicle has entered the battery swap station, the vehicle terminal actively connects to the battery swap station through a fixed SSID and password. After the connection is established, the vehicle terminal actively sends a heartbeat packet containing the VIN to the specified IP; identifies the license plate and obtains the VIN corresponding to the license plate. After the VIN corresponding to the license plate is consistent with the VIN on the vehicle side, the vehicle data is actively sent. The vehicle data may include but is not limited to power-off status, vehicle speed, whether the door is open, battery failure, battery remaining power, etc. Further, the battery swap station terminal sends data and status request information to the corresponding vehicle terminal identified to complete the battery swap of the vehicle. During the battery swap process, the vehicle terminal can feedback data and information status to the battery swap station. After the battery swap is completed, the battery swap station terminal interrupts the connection with the vehicle terminal and waits for a new heartbeat message.

[0032] Embodiment 1

[0033] Figure 2 A flow chart of a control method for a battery locking mechanism provided in Embodiment 1 of the present invention. This embodiment can be applied to the situation of automatically controlling the unlocking of the battery locking mechanism. The method can be executed by a control device of the battery locking mechanism. The control device of the battery locking mechanism can be implemented in the form of hardware and / or software. The control device of the battery locking mechanism can be configured in a vehicle-mounted terminal.

[0034] like Figure 2 As shown, the method includes:

[0035] S110: Receive an unlocking instruction sent by the battery swap station terminal.

[0036] S120. In response to the unlock instruction, generate an unlock trigger signal of an unlock execution component, and output the unlock trigger signal to the unlock execution component, wherein the unlock execution component executes the unlock trigger signal to drive the battery locking mechanism to unlock.

[0037] In an embodiment of the present invention, the communication connection method between the vehicle-mounted terminal and the battery swap station terminal may be wireless communication, and the wireless communication method may include but is not limited to WiFi, Bluetooth, etc., which are not limited here.

[0038] Exemplarily, the vehicle terminal may include a battery swap controller, and the battery swap station terminal may be the station control system of the battery swap station. The battery swap controller and the station control system of the battery swap station are connected and communicated via WiFi. Specifically, WiFi connection is achieved by writing a fixed SSID and WPA encryption, wherein the battery swap station terminal is used as a wireless access point (AP) and the vehicle terminal is used as a receiving end. The battery swap station terminal broadcasts the SSID, and the vehicle terminal automatically connects to WiFi. After the WiFi automatic connection is successful, the communication interface between the battery swap station control is implemented using a communication method based on TCP / IP Socket. The interface uses a Server / Client communication method, with the battery swap controller as the client and the battery swap station terminal as the server.

[0039] In this embodiment, the vehicle terminal can receive the unlocking instruction sent by the battery swap station terminal, generate an unlocking trigger signal of the unlocking execution component in response to the unlocking instruction, and output the unlocking trigger signal to the unlocking execution component, which refers to a component that can control the battery locking mechanism to unlock. The unlocking execution component executes the unlocking trigger signal to drive the battery locking mechanism to unlock, thereby realizing the automatic unlocking of the battery locking mechanism, thereby improving the vehicle battery swapping efficiency.

[0040] In some optional embodiments, the unlocking execution component is a relay, and the battery locking mechanism includes a locking component and an electromagnetic component. Specifically, the relay is closed in response to the unlocking trigger signal, thereby energizing the electromagnetic component to generate magnetic force to unlock the locking component.

[0041] It should be noted that when the battery locking mechanism is a magnetic locking mechanism, the battery locking mechanism can be unlocked by controlling it through a relay; the locking components of the battery locking mechanism can be pushed by the battery swap station stacker to achieve mechanical automatic locking, thereby realizing fully automatic battery swapping. During the battery swapping process, there is no need for manual control of the battery pack unlocking.

[0042] Exemplarily, the unlocking trigger signal may be a high level, that is, the relay is closed after receiving the high level, thereby energizing the electromagnetic components of multiple locking mechanism units to unlock the locking mechanism. It should be noted that the unlocking control of the battery locking mechanism is simple, and the unlocking control can be achieved by only controlling the relay to close and energize the electromagnetic components.

[0043] According to the technical solution of the embodiment of the present invention, the vehicle-mounted terminal can receive the unlocking instruction sent by the battery swap station terminal, and generate an unlocking trigger signal of the unlocking execution component in response to the unlocking instruction, and output the unlocking trigger signal to the unlocking execution component. The unlocking execution component executes the unlocking trigger signal to drive the battery locking mechanism to unlock, thereby realizing automatic unlocking of the battery locking mechanism, thereby improving the vehicle battery swapping efficiency.

[0044] Embodiment 2

[0045] Figure 3 A flowchart of a control method for a battery locking mechanism provided in Embodiment 2 of the present invention. This embodiment adds new technical features based on the above embodiments. Optionally, before outputting the unlock trigger signal to the unlock execution component, it also includes: detecting the locking state of the battery locking mechanism to obtain mechanism state information; correspondingly, outputting the unlock trigger signal to the unlock execution component includes: when the mechanism state information is locked in place, outputting the unlock trigger signal to the unlock execution component.

[0046] like Figure 3 As shown, the method includes:

[0047] S210: Receive an unlocking instruction sent by the battery swap station terminal.

[0048] S220: In response to the unlock instruction, generate an unlock trigger signal of an unlock execution component.

[0049] S230: Detect the locking state of the battery locking mechanism to obtain mechanism state information.

[0050] S240. When the mechanism status information indicates that the battery locking mechanism is locked in place, outputting the unlock trigger signal to the unlock execution component, wherein the unlock execution component executes the unlock trigger signal to drive the battery locking mechanism to unlock.

[0051] Specifically, the locking state of the battery locking mechanism can be detected based on the position sensor to obtain the mechanism state information. Among them, the position sensor can be set near the battery locking mechanism to detect the locking state of the battery locking mechanism. The mechanism state information refers to the position state information of the battery locking mechanism, and the mechanism state information may include but is not limited to locked in place and unlocked in place. Among them, locked in place means that the battery locking mechanism is in a locked state, and the vehicle battery cannot be replaced at this time. Unlocked in place means that the battery locking mechanism is in an unlocked state, and the vehicle battery can be replaced at this time.

[0052] Exemplarily, the battery locking mechanism may include a left locking mechanism and a right locking mechanism. When the position sensor detects that the left locking mechanism is in place and the right locking mechanism is in place, the vehicle-mounted terminal outputs a high level to the relay to drive the relay to close, thereby energizing the electromagnetic component to generate magnetic force to unlock the locking component. In this embodiment, by detecting the state of the battery locking mechanism, it is possible to verify whether the state of the battery locking mechanism is normal, thereby improving the safety of the unlocking process of the battery locking mechanism.

[0053] The technical solution of the embodiment of the present invention outputs an unlocking trigger signal to the unlocking execution component when the mechanism status information indicates that the battery is locked in place, wherein the unlocking execution component executes the unlocking trigger signal to drive the battery locking mechanism to unlock. It should be noted that by detecting the state of the battery locking mechanism, it is possible to verify whether the state of the battery locking mechanism is normal, thereby improving the safety of the unlocking process of the battery locking mechanism.

[0054] Embodiment 3

[0055] Figure 4 A flowchart of a control method for a battery locking mechanism provided in Embodiment 3 of the present invention. This embodiment adds new technical features based on the above embodiments. Optionally, after the unlocking trigger signal is output to the unlocking execution component, it also includes: if the unlocking execution component is closed, the battery locking mechanism is unlocked; if the unlocking execution component is not closed, a solenoid valve drive abnormality signal is sent to the battery swap station terminal.

[0056] like Figure 4 As shown, the method includes:

[0057] S310: Receive an unlocking instruction sent by the battery swap station terminal.

[0058] S320. In response to the unlock instruction, generate an unlock trigger signal of an unlock execution component, and output the unlock trigger signal to the unlock execution component, wherein the unlock execution component executes the unlock trigger signal to drive the battery locking mechanism to unlock.

[0059] S330: If the unlocking execution component is closed, the unlocking state of the battery locking mechanism is detected.

[0060] S340: If the unlocking execution component is not closed, a solenoid valve driving abnormality signal is sent to the battery swap station terminal.

[0061] In the embodiment of the present invention, if the unlocking execution component is closed, indicating that the unlocking execution component is working normally, the unlocking state detection of the battery locking mechanism continues. If the unlocking execution component is not closed, indicating that the unlocking execution component is working abnormally, a solenoid valve driving abnormality signal is sent to the battery swap station terminal to issue a fault alarm.

[0062] For example, if the relay is closed, the battery locking mechanism will continue to be unlocked to verify whether the battery locking mechanism is unlocked successfully. If the relay is not closed, the battery swap connector solenoid valve drive abnormality is reported through WiFi communication, and the battery swap system status is reported as a fault state, and the battery swap system fault fault code 0x04 is reported through CAN communication, where SMU refers to the battery swap controller.

[0063] On the basis of the above embodiments, after the unlocking state detection of the battery locking mechanism, it also includes: when the detection result corresponding to the unlocking state detection is that the unlocking is in place, sending an unlocking success signal to the battery swap station terminal; when the detection result corresponding to the unlocking state detection is that the unlocking is not in place, sending an unlocking abnormality signal to the battery swap station terminal.

[0064] For example, Figure 5 It is a flowchart of unlocking interaction provided by an embodiment of the present invention. The station control system detects that the vehicle is in place. After receiving relevant signals such as the high-voltage connection disconnection state, the vehicle speed is 0, and the handbrake state is locked, the station control system sends an unlocking command to the vehicle terminal; the vehicle terminal receives the unlocking command and executes the unlocking action, and detects whether the left and right sides of the battery locking mechanism are locked in place through the position sensor. When the mechanism status information is locked in place, the SMU battery replacement controller controls the two-way relay to close and drives the electromagnet to attract and unlock; further, it is determined whether the relay is closed. When the relay is not closed, WiFi communication is used to communicate. Report the abnormal driving of the solenoid valve of the battery swap connector, report the battery swap system status as a faulty state, and report the battery swap system fault fault code 0x04 through CAN communication; when the relay is closed, continue to detect whether the battery locking mechanism is in the unlocked state; when the corresponding detection result of the unlocked state detection is unlocked, send an unlocking success signal to the battery swap station terminal; when the corresponding detection result of the unlocked state detection is unlocked not in place, report the battery swap connector unlocking abnormality to the battery swap station terminal, report the battery swap system status as a faulty state, and report the battery swap system fault fault codes 0x06 and 0x07 through CAN communication.

[0065] On the basis of the above embodiments, after sending an unlocking success signal to the battery swap station terminal, it also includes: receiving the battery swap process status sent by the battery swap station terminal; when the battery swap process status is that the battery swap is completed, obtaining the current mechanism status information of the battery locking mechanism; if the current mechanism status information is that the lock is in place, sending a locking success signal to the battery swap station terminal; if the current mechanism status information is that the lock is not in place, sending a locking abnormality signal to the battery swap station terminal.

[0066] For example, Figure 6It is a flowchart of locking interaction provided by an embodiment of the present invention. The vehicle-mounted terminal receives that the battery replacement process status is completed, and detects the left and right battery locking mechanisms through the position sensor. If the left and right battery locking mechanisms are both in the locked state, the battery replacement system status is reported as successful locking through WiFi communication; if the left and right battery locking mechanisms are not both in the locked state, it is determined that the current battery locking mechanism is a locking fault, and the battery replacement connector locking fault is reported as a locking abnormality and the battery replacement system status is a faulty state through WiFi communication; and the battery replacement system fault fault codes 0x06 and 0x07 are reported through CAN communication. Among them, the detection-related information and status of the battery locking mechanism can be sent to the CAN network through CAN.

[0067] According to the technical solution of the embodiment of the present invention, if the unlocking execution component is closed, indicating that the unlocking execution component is working normally, the unlocking state detection of the battery locking mechanism continues. If the unlocking execution component is not closed, indicating that the unlocking execution component is working abnormally, a solenoid valve driving abnormality signal is sent to the battery swap station terminal to issue a fault alarm, thereby improving the safety of the locking mechanism control.
