[0020] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0021] In the related art, the insulation monitoring function of the energy system can be performed by the energy management system. However, when the energy management system is not working, for example, when the battery of a movable device in water is charging, the user triggers the scenario where the energy management system is powered off. In this scenario, the energy management system cannot perform the insulation monitoring function. During the charging process, if the user starts the energy management system, an electric shock accident may occur, posing a great threat to the user's personal safety. In addition, there may be multiple modules with insulation monitoring functions in the energy system. If multiple modules perform insulation monitoring at the same time, the resistance detected by the insulation monitoring circuit may exceed the normal range, thereby falsely reporting insulation faults and affecting the accuracy of insulation monitoring.

[0022] Based on this, see Figure 1 , Figure 1 A structural schematic diagram of a mobile device 100 for water areas provided in an embodiment of the present application, the mobile device 100 for water areas may be, for example, a ship. The mobile device 100 for water areas may include an energy system, the energy system includes an energy management system (EMS) and a battery management system (BMS), the energy management system EMS and the battery management system BMS both have insulation monitoring functions, the main functions of the BMS include real-time monitoring of battery status, management of power batteries of mobile devices for water areas, and enhancement of battery efficiency, the BMS can prevent overcharging and over-discharging of the battery through intelligent management and maintenance of each battery unit, thereby extending the service life of the battery and monitoring the battery status; the function of the EMS is to improve energy efficiency, reduce energy waste, and optimize energy costs by monitoring and controlling the use of energy.

[0023] In addition to the BMS and EMS modules with insulation monitoring functions, the energy system also includes the following modules with insulation monitoring functions: charger, national standard charging equipment, and European standard charging equipment.

[0024] Among them, when EMS is working, its insulation monitoring function is enabled by default.

[0025] When the BMS is working, it identifies the current operating mode and tells other modules through signals whether to turn on the insulation monitoring function. It can also decide whether to turn on its own insulation monitoring function based on the current operating mode.

[0026] The national standard charging equipment is used for shore power DC charging. During operation, the national standard charging equipment performs insulation monitoring from the plug-in to the start of charging, and does not perform insulation monitoring after the start of charging.

[0027] European standard charging equipment can also be used for shore power DC charging. During operation, the European standard charging equipment performs insulation monitoring from plugging in to the end of charging.

[0028] The charger may be, for example, an on-board charger (OBC). The OBC is used for AC charging and can perform insulation monitoring during the charging process. The insulation monitoring function may be enabled or disabled according to the requirements of the entire ship.

[0029] The above-mentioned multiple modules all have insulation monitoring functions. This application determines a module from multiple modules as a target module for executing the insulation monitoring function according to the insulation monitoring requirements of movable equipment in water areas and the functional characteristics of each module, as well as the current operating mode of the energy system determined according to the communication status between the BMS and the remaining modules, and controls the execution of the insulation monitoring functions of multiple modules based on the determination result of the target module, thereby controlling the execution of the insulation function under different operating modes.

[0030] The present application is described in detail below through specific embodiments.

[0031] See also Figure 2 , Figure 2 A flow chart of an insulation monitoring method provided in an embodiment of the present application, the method is applied to a battery management system, the battery management system is applied to an energy system of a mobile device in waters, the energy system includes a plurality of modules with insulation monitoring functions, the modules include the battery management system; the method includes the following steps:

[0032] 201. Determine the current operation mode of the energy system according to the communication status between the local machine and other modules.

[0033] Among them, multiple modules may include a battery management system BMS, an energy management system EMS and a charging device; this machine refers to the BMS, and the remaining modules may include EMS and a charging device. The charging device may include at least one of a charger, a national standard charging device, and a European standard charging device, and may also include other devices with insulation monitoring functions. The BMS can communicate with the EMS and the charging device. The BMS can determine the communication status of the machine and the EMS by detecting the signal of the communication port connected to the EMS. Similarly, the BMS can determine the communication status of the machine and the charging device by detecting the signal of the communication port connected to the charging device.

[0034] The current operating mode may include a charging mode and a discharging mode. In the discharging mode, the EMS is usually in a working state; in the charging mode, the charging device performs a charging task.

[0035] 202. Determine a module from the plurality of modules as a target module for performing an insulation monitoring function based on the current operating mode.

[0036] In the charging mode or the discharging mode, a target module may be determined according to the module currently in working state; when there are more than two modules in working state, the target module may be further determined according to the set priority.

[0037] 203. Control execution of insulation monitoring functions of the plurality of modules based on the determination result of the target module.

[0038] After determining the target module, the target module can be controlled to execute its own insulation monitoring function, and the module that does not need the insulation monitoring function can also be controlled to prohibit insulation monitoring. In this way, it can be ensured that no matter in the charging mode or the discharging mode, there is a target module to execute insulation monitoring, and no more than two modules execute insulation monitoring at the same time.

[0039] In the insulation monitoring method of the present application, the battery management system can determine a target module according to the current operating mode of the energy system to control the target module to perform the insulation monitoring function, thereby meeting the insulation monitoring requirements during the operation of the energy system, and avoiding the situation where more than two modules perform insulation monitoring at the same time, resulting in false alarms of insulation faults.

[0040] Optionally, determining the current operation mode of the energy system according to the communication status between the local unit and other modules includes:

[0041] When it is detected that the energy management system is connected and the charging device is not connected, determining that the current operation mode is a discharge mode;

[0042] The step of determining a module from the plurality of modules as a target module for performing an insulation monitoring function based on the current operation mode includes:

[0045] Sending an insulation monitoring start instruction to the energy management system;

[0046] Deactivate the insulation monitoring function.

[0047] Among them, when the BMS determines that the energy system is in discharge mode, it can determine the EMS as the target module based on the discharge mode, and then the BMS can send an insulation monitoring start instruction to the EMS so that the EMS can perform the insulation monitoring function normally. The BMS will also turn off its own insulation monitoring function, so that in the discharge mode, only the EMS performs insulation monitoring.

[0048] Optionally, determining the current operation mode of the energy system according to the communication status between the local unit and other modules includes:

[0049] When it is detected that the charging device is connected, determining that the current operating mode is a charging mode;

[0050] The step of determining a module from the plurality of modules as a target module for performing an insulation monitoring function based on the current operation mode includes:

[0051] A module is determined from the plurality of modules as a target module for performing an insulation monitoring function based on the charging mode and the type of the charging device.

[0052] Among them, in the charging mode, the target module can be determined according to the type of charging equipment. Specifically, the priority between the EMS and different types of charging equipment can be set in advance, and then, based on the type, a module with a higher priority can be determined to perform insulation monitoring. For example, the priority of the EMS can be set higher than that of the charger and the national standard charging equipment, and the priority of the EMS can be set lower than that of the European standard charging equipment. Then, the target module can be determined from a plurality of the modules based on the charging mode and the type of the charging equipment.

[0053] Optionally, when detecting that the charging device is connected, determining that the current operating mode is a charging mode includes:

[0054] When it is detected that both the charging device and the energy management system are connected, determining that the current operating mode is a first charging mode;

[0055] When it is detected that the charging device is connected and the energy management system is not connected, it is determined that the current operating mode is the second charging mode.

[0056] Among them, the charging mode can be divided into a first charging mode and a second charging mode. In the first charging mode, the EMS is connected; in the second charging mode, the EMS is not connected. Furthermore, whether the EMS is connected can be used to determine whether insulation monitoring is performed by the EMS or the charging device.

[0057] Optionally, the charging device includes a charger; and the determining a module from the plurality of modules as a target module for performing the insulation monitoring function based on the charging mode and the type of the charging device includes:

[0060] Sending an insulation monitoring start instruction to the energy management system;

[0061] sending a disable insulation monitoring instruction to the charger;

[0062] Deactivate the insulation monitoring function.

[0063] In the first charging mode, the EMS is connected. According to the type of charging equipment, the priority of the EMS is higher than that of the charger. Therefore, the EMS can perform insulation monitoring. At the same time, it is necessary to turn off the insulation monitoring function of the BMS and send a disable insulation monitoring instruction to the charger to prevent more than two modules from performing insulation monitoring at the same time.

[0064] Optionally, the charging device includes a charger; and the determining a module from the plurality of modules as a target module for performing the insulation monitoring function based on the charging mode and the type of the charging device includes:

[0065] When the current operation mode is the second charging mode, determining the local device as the target module;

[0067] sending a disable insulation monitoring instruction to the charger;

[0068] Turn on the insulation monitoring function of this unit.

[0069] In the second charging mode, the EMS is not connected, therefore, insulation monitoring is not performed through the EMS; according to the type of charging equipment, the BMS has a higher priority than the charger, and thus, insulation monitoring can be performed by the BMS. The BMS can turn on the insulation monitoring function of the charger, and at the same time, a disable insulation monitoring instruction needs to be sent to the charger to prevent more than two modules from performing insulation monitoring at the same time.

[0070] Optionally, the charging device includes a national standard charging device, and the determining a module from the plurality of modules as a target module for performing the insulation monitoring function based on the charging mode and the type of the charging device includes:

[0071] When the current operating mode is the first charging mode, determining the energy management system as the target module;

[0073] Turn off its own insulation monitoring function;

[0074] Sending a disable insulation monitoring instruction to the national standard charging device;

[0075] Send an insulation monitoring start instruction to the energy management system.

[0076] Among them, in the first charging mode, EMS is connected. According to the type of charging equipment, the priority of EMS is higher than that of national standard charging equipment. Therefore, insulation monitoring can be performed by EMS. At the same time, it is necessary to turn off the insulation monitoring function of BMS and send a disable insulation monitoring instruction to the national standard charging equipment to prevent more than two modules from performing insulation monitoring at the same time.

[0077] Optionally, the controlling the execution of the insulation monitoring functions of the plurality of modules based on the determination result of the target module further includes:

[0078] In the first stage, a command to disable insulation monitoring is sent to the energy management system;

[0079] In the second stage, a step of sending a disabling insulation monitoring instruction to the national standard charging device is executed;

[0080] Among them, the first stage is the stage where the local device detects that the national standard charging device is connected, and the national standard charging device has not started to output the charging current, and the second stage is the stage where the national standard charging device starts to output the charging current.

[0081] In the first stage, insulation monitoring is performed by the national standard charging equipment. In order to avoid the situation where the national standard charging equipment and EMS perform insulation monitoring at the same time, a command to disable insulation monitoring can be sent to the EMS in the first stage; in the second stage, insulation monitoring is switched to the EMS.

[0082] Optionally, the charging device includes a national standard charging device; and the step of determining a module from the plurality of modules as a target module for performing an insulation monitoring function based on the charging mode and the type of the charging device includes:

[0083] When the current operation mode is the second charging mode, determining the local device as the target module;

[0084] The controlling the execution of the insulation monitoring functions of the plurality of modules based on the determination result of the target module comprises:

[0085] Sending a disable insulation monitoring instruction to the national standard charging device;

[0086] Turn on the insulation monitoring function of this unit.

[0087] Among them, in the second charging mode, EMS is not connected, therefore, insulation monitoring is not performed through EMS; according to the type of charging equipment, BMS has a higher priority than national standard charging equipment, and thus, insulation monitoring can be performed by BMS. BMS can turn on the insulation monitoring function of the machine. At the same time, it is necessary to send a disable insulation monitoring instruction to the national standard charging equipment to prevent more than two modules from performing insulation monitoring at the same time.

[0088] The controlling the execution of the insulation monitoring functions of the plurality of modules based on the determination result of the target module further includes:

[0089] In the first stage, the insulation monitoring function is turned off.

[0090] In the second stage, a step of sending an insulation monitoring disablement instruction to the national standard charging device is performed.

[0091] Among them, the first stage is the stage where the local device detects that the national standard charging device is connected, and the national standard charging device has not started to output the charging current, and the second stage is the stage where the national standard charging device starts to output the charging current.

[0092] In the first stage, insulation monitoring is performed by the national standard charging equipment. In order to avoid the situation where the national standard charging equipment and BMS perform insulation monitoring at the same time, the BMS can first turn off its own insulation monitoring function in the first stage; in the second stage, insulation monitoring is switched to the BMS.

[0093] Optionally, the charging device includes a European standard charging device; and the step of determining a module from the plurality of modules as a target module for performing an insulation monitoring function based on the charging mode and the type of the charging device includes:

[0094] When the current operating mode is the first charging mode, determining the European standard charging device as the target module;

[0095] The controlling the execution of the insulation monitoring functions of the plurality of modules based on the determination result of the target module comprises:

[0096] sending a disable insulation monitoring instruction to the energy management system;

[0097] Turn off its own insulation monitoring function;

[0098] Send an insulation monitoring start instruction to the European standard charging device.

[0099] In the first charging mode, the EMS is connected. According to the type of charging equipment, the priority of the EMS is lower than that of the European standard charging equipment. Therefore, the European standard charging equipment can perform insulation monitoring. At the same time, it is necessary to turn off the insulation monitoring function of the BMS and send a disable insulation monitoring instruction to the EMS to prevent more than two modules from performing insulation monitoring at the same time.

[0100] Optionally, the charging device includes a European standard charging device; and the step of determining a module from the plurality of modules as a target module for performing an insulation monitoring function based on the charging mode and the type of the charging device includes:

[0101] When the current operating mode is the second charging mode, determining the European standard charging device as the target module;

[0102] The controlling the execution of the insulation monitoring functions of the plurality of modules based on the determination result of the target module comprises:

[0103] Send an insulation monitoring start instruction to the European standard charging device.

[0104] Deactivate the insulation monitoring function.

[0105] In the second charging mode, the EMS is not connected, therefore, insulation monitoring is not performed through the EMS; according to the type of charging equipment, the priority of the BMS is lower than that of the European standard charging equipment, and thus, the European standard charging equipment can perform insulation monitoring. The BMS sends an insulation monitoring start instruction to the European standard charging equipment, and can turn off its own insulation monitoring function to prevent more than two modules from performing insulation monitoring at the same time.

[0106] Optionally, the insulation monitoring method further includes:

[0107] Receiving insulation monitoring results fed back by the energy management system;

[0108] If the insulation monitoring result is a preset fault monitoring result, the discharge circuit is controlled to be disconnected.

[0109] Among them, in the discharge mode, if the first insulation monitoring result is the preset fault monitoring result, it indicates that an insulation fault is detected, and the discharge circuit can be disconnected through the BMS control to ensure safety.

[0110] Optionally, the action of the BMS determining the operating mode of the energy system can be performed when the BMS is first powered on. Furthermore, during the operation of the energy system, its operating mode may change due to user operations or the triggering of its own management mechanism. Therefore, during the operation of the energy system, the BMS also needs to detect in real time or periodically whether the operating mode of the energy system has changed, that is, the action of the BMS determining the operating mode of the energy system can also be performed during the power-on process of the BMS.

[0111] In one example, when the BMS is first powered on, it detects that the current operating mode of the energy system is the discharge mode. In this discharge mode, the BMS will continue to monitor whether there is a charging device connected, for example, it can detect whether there is a charging signal, and after detecting the charging signal, it determines which type of charging device the charging signal comes from. When it is confirmed that a charging device is connected, it is confirmed that it is currently in the first charging mode, and the insulation monitoring strategy in the first charging mode is executed. In the first charging mode, the BMS can also continue to monitor whether it has switched to the discharge mode, and when it is confirmed that it has switched to the discharge mode, it executes the insulation monitoring strategy in the discharge mode. In the discharge mode, the BMS will continue to monitor whether there is a charging device connected. Such a cycle is repeated until a charging process or a discharging process in the process ends.

[0112] In another example, when the BMS is first powered on, it detects that the current operating mode of the energy system is charging mode. In this charging mode, the BMS will continue to monitor whether it has switched to discharge mode. When it is confirmed that it has switched to discharge mode, the insulation monitoring strategy in discharge mode is executed. In discharge mode, the BMS will continue to monitor whether there is a charging device connected. When it is confirmed that there is a charging device connected, it is confirmed that it is currently in charging mode and the insulation monitoring strategy in charging mode is executed. In charging mode, the BMS will continue to monitor whether it has switched to discharge mode. This cycle repeats until a charging process or a discharging process in the process ends.
