DETAILED DESCRIPTION

[0046] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are

[0047] These are some, but not all, embodiments of the present invention.

[0048] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in the present application without creative work are within the scope of protection of the present application.

It is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on this application.

[0050] In addition, the terms "first," "second," and the like in the description and claims of the present invention and the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a particular order or precedence. It should be understood that the terms used in this manner are interchangeable 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," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to these processes, methods, products, or apparatus.

[0051] It should be noted that, in the absence of conflict, the features in the embodiments of this application can be combined with each other.

[0052] During the charging process at the battery swap station, since the battery management unit of the target energy storage module in the charging bay on the market follows the international communication protocol with the standard charging system, the battery swap station control equipment cannot participate in it and cannot obtain the relevant data in the charging bay. Moreover, when the battery swap station control equipment needs to obtain the relevant data of the charging bay, it is necessary to require the adaptability protocol between the battery swap station control equipment and the charging bay to be redeveloped. At the same time, the standard target charging equipment and the battery swap station control equipment are not interconnected. When the battery swap station control equipment needs to obtain the relevant data of the target charging equipment, the battery swap station control equipment and the target charging equipment also need to have an adaptability protocol, and the target charging equipment is developed non-standardly. It can be seen that there is a protocol mismatch problem between the battery swap station control equipment, the charging bay, and the target charging equipment.

[0053] Therefore, in order to monitor the status of each charging position in real time when charging at a battery swap station and solve the problem of protocol mismatch between the battery swap station control equipment, charging positions, and target charging equipment, this application provides a battery swap station charging monitoring system. Figure 1 This is a schematic diagram of the structure of a battery swap station charging monitoring system provided in an embodiment of the present application. Figure 1 As shown, the battery swap station charging monitoring system includes: a battery swap station control device 110, a plurality of charging positions 130, a plurality of target charging devices 140 and a plurality of charging monitoring devices 120, wherein the plurality of charging positions 130 are respectively used to accommodate a plurality of target energy storage modules 131, and the plurality of charging positions 130 are respectively connected to a plurality of target charging devices 140, and the first communication interface, the second communication interface and the third communication interface of the control module 121 in each charging monitoring device 120 are respectively connected to the battery swap station control device 110, the signal end of the battery management unit in a target energy storage module 131 and a target The signal end of the target charging device 140, wherein the target charging device 140 is connected to the target energy storage module 131 through a charging gun. If there are N charging positions 130, the N charging positions 130 may include: charging position 1, charging position 2...charging position n. Similarly, if there are N target charging devices 140 and N charging monitoring devices 120, the N target charging devices 140 may include: target charging device 1, target charging device 2...target charging device n, and the N charging monitoring devices 120 may include: charging monitoring device 1, charging monitoring device 2...charging monitoring device n.

[0054] Among them, the battery swap station control device 110 is the customer's battery swap station control center, which is used to coordinate the operation of the battery swap station. The target energy storage module 131 in the charging position 130 can be a battery module that is generally suitable for electric vehicles, which is used to store power and provide power to electric vehicles. The target charging device 140 is all target charging devices 140 on the market that comply with international agreements, such as charging piles. The charging monitoring device 120 is used to simultaneously connect the charging position 130, the target charging device 140 and the battery swap station control device 110 to realize interaction with the charging position 130, the target charging device 140 and the battery swap station control device 110.

[0055] The first signal relay 122 in each charging monitoring device 120 is connected to the signal end of the battery management unit in a target energy storage module 131 , and the second signal relay 123 in each charging monitoring device 120 is connected to the battery swap station control device 110 .

[0056] Each charging monitoring device 120 provides a signal to the signal end of the battery management unit in the target energy storage module 131 through the first signal relay 122 to realize control of the battery management unit. At the same time, each charging monitoring device 120 provides a signal to the battery swap station control device 110 through the second signal relay 123, so that the battery swap station control device 110 can receive the working status of the charging position 130 fed back by the second signal relay 123. Therefore, each charging monitoring device 120 can serve as a bridge for information interaction between the charging position 130, the target charging device 140 and the battery swap station control device 110.

[0057] The charging control method provided in this application is specifically described below through multiple examples in conjunction with the accompanying drawings.

[0058] The embodiment of the present application provides a possible implementation of a charging control method, which is applied to a control module in a charging monitoring device. Figure 2 A flow chart of a charging control method provided in an embodiment of the present application is shown as follows: Figure 2 As shown, the method includes:

[0059] S101. Obtain a charging command from a battery swap station control device.

[0060] In this embodiment, since the control module of the charging monitoring device is connected to the battery swap station control device through the first communication interface, the control module can receive relevant commands issued by the battery swap station control device, which may include: charging commands and stop charging commands, etc.

[0061] S102. According to the charging command, the first signal relay in the charging monitoring device is controlled to close to send a charging control signal to the battery management unit of the target energy storage module placed in the target charging position corresponding to the charging monitoring device. The charging control signal is used to enable the target charging device corresponding to the target charging position to start charging the target energy storage module.

[0062] Specifically, a charging monitoring device is connected to a target charging position and a target charging device. When a charging monitoring device obtains a charging command issued by the battery swap station control device, the control module in the charging monitoring device controls the first signal relay to close according to the obtained charging command, and sends a charging control signal to the battery management unit of the target energy storage module in the target charging position, thereby controlling the battery management unit of the target energy storage module through the first signal relay, so that the battery management unit of the target energy storage module can be in a state to be charged, and the target charging device starts to charge the target energy storage module in the state to be charged.

[0063] It should be noted that when the battery swap station control device needs to obtain relevant data of the target energy storage module in the target charging position, such as obtaining the coding, power, temperature and other relevant data of the target energy storage module, the battery swap station control device will send relevant commands to the charging monitoring device, such as the data acquisition command, and the control module will control the first signal relay to close, and send a wake-up signal to the battery management unit of the target energy storage module in the target charging position to wake up the battery management unit of the target energy storage module, thereby obtaining the relevant data of the target energy storage module, and parsing the relevant data through the control module and uploading it to the battery swap station control device, so that the battery swap station control device can accurately monitor and display the relevant information of the target energy storage module in each charging position, wherein the control module controls the first signal relay to close, and sends different voltage signals to the battery management unit of the target energy storage module in the target charging position, so that the battery management unit of the target energy storage module is in different working states.

[0064] S103, control the second signal relay in the charging monitoring device to close, so as to send the first signal to the battery swap station control device.

[0065] A charging status signal indicates that the target charging position is in a charging state.

[0066] When the target charging device corresponding to the target charging position charges the target energy storage module, indicating that the target charging position is in a charging state, the control module controls the second signal relay to close and sends a first charging state signal to the battery swap station control device, so that the battery swap station control device receives the information that the target charging position is in a charging state, wherein the first charging state signal can be a high-level signal. When the battery swap station control device receives the high-level signal, it indicates that the target charging position is in a charging state.

[0067] When the target charging device corresponding to the target charging position stops charging the target energy storage module, optionally, based on the charging end signal received from the battery management unit of the target charging device and / or the target energy storage module, the second signal relay is controlled to disconnect to send a second charging status signal to the battery swap station control device to indicate that the target charging position is in a non-charging state.

[0068] Among them, the second charging status signal can be a low-level signal. When the battery swap station control device receives the low-level signal, it indicates that the target charging position is in a non-charging state.

[0069] In summary, a charging control method provided in an embodiment of the present application is applied to a control module in a charging monitoring device, and the method includes: obtaining a charging command from a battery swap station control device, and according to the charging command, controlling the first signal relay to close to send a charging control signal to the battery management unit of the target energy storage module placed in the target charging position corresponding to the charging monitoring device, the charging control signal is used to enable the target charging device corresponding to the target charging position to start charging the target energy storage module, and then controlling the second signal relay to close to send a first charging status signal to the battery swap station control device to indicate that the target charging position is in a charging state. The method of the present application receives the charging command of the battery swap station control device through the charging monitoring device, and controls the first signal relay to enable the target energy storage module to be charged, and controls the second signal relay to enable the battery swap station control device to receive the charging status of the target energy storage module, thereby enabling the charging monitoring device to realize data interaction among the target energy storage module, the battery swap station control device, and the target charging device.

[0070] The embodiment of the present application further provides a possible implementation of a charging control method. If the charging monitoring device further includes: a power module and a power relay, before controlling the first signal relay in the charging monitoring device to close according to the charging command, the method further includes:

[0071] The power relay is controlled to be closed, so that the power module supplies power to the battery management unit of the target energy storage module through the power relay.

[0072] Specifically, when the battery swap station control device needs to obtain relevant data of the target energy storage module in the target charging position, the battery swap station control device will send relevant commands to the charging monitoring device, such as a data acquisition command. The control module will first control the power relay to close, so that the power module supplies power to the battery management unit of the target energy storage module through the power relay. The control module then obtains the relevant data of the target energy storage module, and parses the relevant data through the control module and uploads it to the battery swap station control device, so that the battery swap station control device can accurately monitor and display the relevant information of the target energy storage module in each charging position.

[0073] The embodiment of the present application also provides another possible implementation of the charging control method. Figure 3 A flow chart of another charging control method provided in an embodiment of the present application is shown as follows: Figure 3 As shown, if the first signal relay includes: a first relay, a second relay, and a third relay; according to the charging command, controlling the first signal relay in the charging monitoring device to close includes:

[0074] S201. According to a charging command, control a first relay to close to send a mode activation signal to a battery management unit of a target energy storage module, so that the battery management unit of the target energy storage module meets a charging condition.

[0075] S202: Control the second relay to close to send a first wake-up signal to the battery management unit of the target energy storage module, so that the battery management unit of the target energy storage module enters a charging waiting state.

[0076] S203. Based on the charging wake-up signal received from the target charging device, control the third relay to close to send a second wake-up signal to the battery management unit of the target energy storage module. The second wake-up signal is used to enable the battery management unit of the target energy storage module to exchange charging messages with the target charging device, so that the target charging device starts charging the target energy storage module.

[0077] In this embodiment, if the first relay is a charging mode signal relay, the battery management unit can satisfy the charging conditions according to the received mode activation signal; if the second relay is a battery management unit wake-up signal relay, the battery management unit can enter the charging waiting state according to the received first wake-up signal; if the third relay is a charging wake-up signal relay, the battery management unit can interact with the target charging device through charging messages according to the received second wake-up signal, and enable the target charging device to start charging the target energy storage module.

[0078] The control module can control different relays to put the battery management unit of the target energy storage module into different working states.

The first communication interface, the second communication interface, and the third communication interface of the control module 121 are used to communicate with the battery swap station control device 110, the target energy storage module 131, and the target charging device 140. The battery management unit and the target charging device 140 communicate with each other to realize data interaction. The control module 121 can be a CPU to realize the control of the charging monitoring device 120.

Among them, the first output end is the D0 control output end of the control module 121, which is responsible for controlling and driving the first signal relay 122 and the second signal relay 123.
