[0019] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are 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 are within the scope of protection of the present invention.

[0020] In the field of electric two-wheeled vehicles, the convenience and safety of charging and swapping cabinets have always been the focus of people's attention. However, many current charging and swapping cabinets still have many imperfect problems in terms of safety and fire protection. For example, the passively triggered aerosol fire protection solution currently widely used on the market is not ideal in actual application after the battery thermal runaway, and it is difficult to effectively control the fire, and the safety of the charging and swapping cabinet cannot be guaranteed. For another example, the water fire fighting system used in some charging and swapping cabinets, although it has the ability to actively extinguish fires, has the problem of untimely response; and it also has extremely high requirements for the sealing performance of the compartment door, which requires the compartment door to be sealed for a long time and leak-proof. However, in actual application, as time goes by, the compartment door material ages, and the compartment door sealing performance is difficult to guarantee, which further increases safety hazards.

[0021] In this regard, the present invention provides a fire control method for a charging and swapping cabinet, which aims to set a fire-fighting device outside the charging and swapping cabinet, and when it is judged that the battery has a thermal runaway problem based on the temperature information and battery information of the charging and swapping cabinet, the fire-fighting device is controlled to open by an electromagnetic valve to perform fire-fighting treatment on the charging and swapping cabinet. In this process, there is no need to rely on the sealing performance of the compartment door, and thermal runaway can be identified before it occurs, and fire-fighting measures can be taken in time to respond, thereby greatly improving the safety of the charging and swapping cabinet and ensuring the safety of equipment and personnel.

[0022] Figure 1 is a flow chart of the fire control method for the charging and swapping cabinet provided by the present invention, such as Figure 1 As shown, the execution subject of the method is the cabinet control board. The method includes: Step 110, obtaining temperature information and battery information of the charging and swapping cabinet; Step 120, based on the temperature information and the battery information, perform a thermal runaway detection on the battery in the charging and swapping cabinet to obtain a thermal runaway detection result; Step 130, when the thermal runaway detection result indicates that the battery in the charging and swapping cabinet has a thermal runaway problem, control the solenoid valve in the charging and swapping cabinet to open, so that the fire protection device performs fire protection control on the charging and swapping cabinet; Among them, the fire-fighting device is arranged outside the charging and swapping cabinet, and the fire-fighting device is connected to the charging and swapping cabinet through a fire-fighting pipe. A nozzle is arranged at one end of the fire-fighting pipe, and the nozzle is controlled by a solenoid valve.

[0023] It is understandable that during the actual operation of the charging and swapping cabinet, due to various reasons, such as temperature, pressure difference, etc., the internal battery may have thermal runaway problems, causing fires and injuring equipment and personnel. The process of battery thermal runaway is as follows: at the beginning of thermal runaway, a single battery cell reacts and releases a large amount of smoke, while the temperature rises, further affecting other batteries. When the energy of thermal runaway cannot be effectively released, it will catch fire. At this time, if it is in a sealed environment, it will explode.

[0024] In order to avoid the adverse consequences of thermal runaway of batteries in the charging and swapping cabinet, in the embodiments of the present invention, it is proposed to identify thermal runaway before it occurs, and to take timely measures to control it when thermal runaway is identified. The whole process does not need to rely on the sealing performance of the compartment door, and can also have a better effect on the thermal runaway problem.

[0025] Specifically, before performing fire control on the charging and swapping cabinet, the first thing to be determined is the object to be controlled, which is the charging and swapping cabinet in this case. The charging and swapping cabinets to be controlled can be one or more, and the embodiment of the present invention does not specifically limit this. In actual application, in order to facilitate management and control, the cabinets can be divided into areas, and fire control can be performed on the charging and swapping cabinets in each area.

[0026] After determining the charging and swapping cabinet to be controlled, in the embodiment of the present invention, the internal battery information and the temperature information in the compartment can be obtained, that is, the temperature information and battery information of the charging and swapping cabinet can be obtained. The temperature information here can be obtained by temperature detection equipment, such as temperature sensors, thermometers, etc., and the battery information can be obtained through the battery management system BMS (Battery Management System). The battery information here can include information on battery voltage, current, internal pressure difference, temperature, and temperature change rate.

[0027] It should be noted that the acquisition of temperature information and battery information is a continuous process, that is, the charging and swapping cabinet needs to be continuously monitored to obtain the temperature information of the charging and swapping cabinet over a period of time and the information of its internal battery.

[0028] Furthermore, after obtaining the temperature information and battery information of the charging and swapping cabinet, in an embodiment of the present invention, thermal runaway detection can be performed based on this to identify whether the charging and swapping cabinet currently has a thermal runaway problem, thereby obtaining a thermal runaway detection result. Here, it can be specifically based on the temperature information and battery information obtained over a period of time, and an analysis can be performed to determine whether the battery in the charging and swapping cabinet has a thermal runaway problem, that is, whether a thermal runaway phenomenon will occur, through the temperature changes, battery voltage, current, battery internal pressure difference, temperature change rate, etc. reflected by these two during this period of time in the charging and swapping cabinet, thereby obtaining a thermal runaway detection result.

[0029] After that, if the thermal runaway detection results show that the battery in the charging and swapping cabinet currently has a thermal runaway problem, that is, the battery in the charging and swapping cabinet will cause thermal runaway, and the charging and swapping cabinet will have a greater safety hazard, at this time, measures can be taken to deal with it, that is, the fire-fighting device can be started to carry out fire-fighting treatment on the charging and swapping cabinet, so as to reduce the safety hazard through fire-fighting treatment, thereby avoiding fire and explosion caused by thermal runaway problems to the greatest extent and improving safety performance.

[0030] Specifically, here, when the thermal runaway detection result indicates that the battery in the charging and swapping cabinet has a thermal runaway problem, the fire-fighting device is activated to control the fire-fighting of the charging and swapping cabinet. However, considering the stringent requirements of the current water fire-fighting system on the sealing of the door, and the poor performance in the timeliness of response, in the embodiment of the present invention, it is proposed that an external fire-fighting device can be connected to the charging and swapping cabinet through a fire-fighting pipe, so as to avoid the requirements for the sealing performance of the door, and ensure a good fire-fighting effect without good sealing.

[0031] Figure 2 Schematic diagram of the connection between the fire fighting device and the charging and swapping cabinet provided by the present invention, such as Figure 2As shown, the fire-fighting device is arranged outside the charging and swapping cabinet, and is connected to the charging and swapping cabinet through a fire-fighting pipe. A nozzle is arranged at one end of the fire-fighting pipe connected to the charging and swapping cabinet, and the nozzle is controlled by a solenoid valve. Under normal circumstances, the fire-fighting device is in a non-starting state, and the solenoid valve is closed; when the thermal runaway detection result shows that the battery has a thermal runaway problem, the fire-fighting device is started, that is, the solenoid valve in the corresponding compartment (the charging compartment in the charging and swapping cabinet) is controlled to open, so that the fire-fighting material in the fire-fighting device can be sprayed into the corresponding compartment through the nozzle, thereby realizing fire-fighting control.

[0032] Here, the charging compartment in the charging and swapping cabinet can be one or more. Figure 2 As shown, there are two charging compartments in the charging and swapping cabinet. Both charging compartments are connected to the fire-fighting equipment through fire-fighting pipes. A solenoid valve is provided on the fire-fighting pipe of each charging compartment, and the fire-fighting control of each charging compartment is achieved by switching the solenoid valve.

[0033] Among them, the fire-fighting material installed in the fire-fighting device for fire-fighting treatment can be water, perfluorohexanone, etc., or other substances that are helpful for fire-fighting, and the embodiment of the present invention does not specifically limit this. It is worth noting that in order to facilitate the deployment and maintenance of the fire-fighting device, the fire-fighting device is mostly set at a low position relative to the charging and swapping cabinet. At this time, for the charging compartments placed vertically at a high position, when fire-fighting treatment is required, the fire-fighting material in the fire-fighting device is difficult to be smoothly sprayed into the charging compartment through the fire-fighting pipes and nozzles. Based on this, in the embodiment of the present invention, the fire-fighting device is preferably a high-pressure fire-fighting device to achieve better spraying through high pressure.

[0034] In the embodiment of the present invention, the solenoid valve is controlled based on the thermal runaway detection result, and the fire-fighting device can be activated in time when the battery has a thermal runaway problem, and the battery in the abnormal compartment can be subjected to fire-fighting treatment. This can not only effectively identify each abnormal compartment, but also does not require the sealing performance of the compartment door, which greatly improves the handling effect of the thermal runaway problem, enhances the safety of the charging and swapping cabinet, and reduces the manufacturing cost of the charging and swapping cabinet compartment door.

[0035] The fire protection control method for a charging and swapping cabinet provided by the present invention performs thermal runaway detection on the battery in the charging and swapping cabinet based on the temperature information and battery information of the charging and swapping cabinet. When the thermal runaway detection result indicates that the battery has a thermal runaway problem, the solenoid valve in the charging and swapping cabinet is controlled to open, so that the fire protection device performs fire protection control on the charging and swapping cabinet. The fire protection device is arranged outside the charging and swapping cabinet, and the fire protection device is connected to the charging and swapping cabinet through a fire protection pipe. A nozzle is arranged at one end of the fire protection pipe, and the nozzle is controlled by the solenoid valve. The defects of the traditional solution that the fire protection measures of the charging and swapping cabinet are limited in effect after the thermal runaway problem occurs, effective cooling treatment cannot be performed, and the cooling method depends on the sealing characteristics of the compartment door are overcome. The solenoid valve is controlled by the thermal runaway detection result, and the charging and swapping cabinet can be effectively and promptly treated with fire protection under abnormal circumstances, with better cooling effect, and the problem can be identified before it occurs, so that prevention can be better performed, thereby further improving the safety performance of the battery swapping cabinet.

[0036] Based on the above embodiment, step 130 includes: When the thermal runaway detection result indicates that the battery in the charging and swapping cabinet has a thermal runaway problem, the solenoid valve in the charging and swapping cabinet is controlled to open and last for a first preset time, so that the fire fighting device performs fire fighting control on the charging and swapping cabinet; Obtain the temperature information and battery information of the charging and swapping cabinet after the last fire control, and perform thermal runaway detection based on the re-obtained temperature information and battery information; When the thermal runaway detection result obtained by re-testing indicates that there is no thermal runaway problem in the battery in the charging and swapping cabinet, the solenoid valve in the charging and swapping cabinet is controlled to open after the second preset time and lasts for the third preset time, so that the fire-fighting device can perform fire-fighting control on the charging and swapping cabinet.

[0037] Specifically, in step 130, the process of performing fire control on the charging and swapping cabinet may include the following steps: Considering that the current fire protection scheme of the charging and swapping cabinet has not only the problem of the sealing of the compartment door, but also the problem of insufficient cooling time and short duration, it is unable to better ensure the safety of the charging and swapping cabinet. For example, the passively triggered perfluorohexanone scheme is triggered after thermal runaway and has a cooling effect, but the duration is not long enough and it is difficult to support the 30-minute thermal runaway time, thus failing to eliminate safety hazards and ensure the safety characteristics of the charging and swapping cabinet.

[0038] In view of this, in an embodiment of the present invention, a phased fire control scheme is proposed; that is, when the thermal runaway detection result indicates that the battery in the charging and swapping cabinet has a thermal runaway problem, the solenoid valve in the charging and swapping cabinet is first controlled to open, and then closed after a first preset time, so that the fire-fighting device can perform fire control on the charging and swapping cabinet; after the first preset time, the solenoid valve is closed to stop the fire-fighting treatment. The first preset time here can be 5 seconds, 10 seconds, 15 seconds, etc., and should not be too long. Then, the temperature information and battery information can be reacquired to obtain the temperature information and battery information of the charging and swapping cabinet within a period of time after the last fire control, and the thermal runaway detection can be performed again based on this to obtain the thermal runaway detection result. Furthermore, if the thermal runaway detection result obtained by re-detection indicates that there is no thermal runaway problem in the battery in the charging and swapping cabinet, at this time, you can wait for a period of time before opening the solenoid valve, that is, you can wait for the second preset time and then control the solenoid valve in the charging and swapping cabinet to open, and continue for the third preset time, and then close it, re-acquire the temperature information and battery information, and repeat the above process until the cumulative time the solenoid valve is open exceeds the fourth preset time.

[0039] Among them, the second preset time and the third preset time can be set according to actual needs, and they can be the same as or different from the first preset time, and the embodiment of the present invention does not make specific restrictions on this. The fourth preset time is the pre-set processing time of the thermal runaway problem. To ensure safety, the automated thermal runaway processing needs to continue for a period of time (generally 30 minutes) until the management personnel arrive. Based on this, the fourth preset time in the embodiment of the present invention can be 30 minutes, 35 minutes, etc., and can also be determined based on the relative distance between the charging and swapping cabinet and the management personnel. The embodiment of the present invention does not make specific restrictions on this.

[0040] It should be noted that after a thermal runaway problem is detected, the detection result will be reported to the platform so that management personnel can be aware of the situation in a timely manner and take action.

[0041] Based on the above embodiment, thermal runaway detection is performed based on the re-acquired temperature information and battery information, and then further includes: When the thermal runaway detection result obtained by re-testing indicates that the battery in the charging and swapping cabinet still has a thermal runaway problem, the solenoid valve in the charging and swapping cabinet is controlled to open and continue for a first preset time length until the cumulative time that the solenoid valve in the charging and swapping cabinet is open exceeds a fourth preset time length, or the thermal runaway detection result obtained by the latest test indicates that the battery in the charging and swapping cabinet does not have a thermal runaway problem.

[0042] Specifically, after the above re-testing obtains the thermal runaway detection result, if the thermal runaway detection result at this time indicates that the battery in the charging and swapping cabinet still has a thermal runaway problem, the solenoid valve can be immediately controlled to open to continue firefighting treatment of the charging and swapping cabinet; that is, the solenoid valve in the charging and swapping cabinet can be controlled to open, and then closed after the first preset time; re-acquire information for thermal runaway detection, and repeat the above process until the cumulative opening time of the solenoid valve in the charging and swapping cabinet exceeds the fourth preset time, or it is detected that there is no thermal runaway problem. If there is no thermal runaway problem, wait for the second preset time before opening the solenoid valve, and continue for the third preset time.

[0043] The following is an example of fire protection for battery thermal runaway: When a thermal runaway problem is detected in the battery, the solenoid valve is first controlled to open for 10 seconds and then closed. Then, the temperature information and battery information within a period of time are re-acquired, and thermal runaway detection is performed again based on this. If the test result at this time shows that the battery is still in a thermal runaway state, the solenoid valve is controlled to open and continue to spray for 10 seconds, then closed, and re-tested, and repeated in sequence. If the test result at this time shows that the battery does not continue to experience thermal runaway, you can wait for 1 minute, then control the solenoid valve to open, spray to cool down, and then close it, and re-test until the cooling treatment lasts for more than 30 minutes.

[0044] In the embodiment of the present invention, through a staged cooling process, information is re-acquired for detection after each cooling, and corresponding measures are taken for processing according to the detection results. While ensuring the cooling effect, the cooling treatment time can be extended to the maximum extent until manual processing is taken over, which well optimizes the cooling effect and greatly improves the safety of the charging and swapping cabinet.

[0045] Based on the above embodiment, step 120 includes: Based on the temperature information within a preset period, determine the temperature change trend and the severity of the change; Based on the temperature change trend and severity of the change, as well as the battery information within a preset time period, thermal runaway detection is performed on the battery in the charging and swapping cabinet to obtain the thermal runaway detection results.

[0046] Specifically, in step 120, the process of performing thermal runaway detection on the battery in the charging and swapping cabinet according to the temperature information and the battery information to obtain the thermal runaway detection result may specifically include: First, based on the temperature information obtained over a period of time, the temperature changes in the charging and swapping cabinet during this period can be analyzed to determine whether it is a small-range fluctuation or a substantial increase, so that the thermal runaway state of the battery can be predicted based on this during subsequent thermal runaway detection.

[0047] Here, specifically, the temperature information obtained within the preset time period can be used as the basis for analysis and prediction to determine the temperature change trend and the severity of the change during this period. The analysis process here can be performed on the basis of each data collected during this period. For example, based on each temperature data and the adjacent temperature data, the temperature change and the rate of change can be determined. It can also be performed on the basis of the entire time period. For example, the overall temperature change trend and the severity of the temperature change can be analyzed during this period.

[0048] Next, based on the temperature change trend and severity of the change during this period obtained in the previous step, thermal runaway detection can be performed in combination with the battery information during this period to obtain the thermal runaway detection result of the battery in the charging and swapping cabinet.

[0049] Here, specifically, the state of the battery during this period can be analyzed based on the temperature change trend and the severity of the change during this period, as well as the battery information obtained by analysis. Specifically, it can be determined whether the battery is in a thermal runaway state and whether a thermal runaway problem will occur through the temperature change caused by the battery, the internal pressure difference of the battery, the battery voltage, the current, etc. reflected in the above information, thereby obtaining a thermal runaway detection result.

[0050] Based on the above embodiment, based on the temperature change trend and the severity of the change, as well as the battery information within a preset period of time, a thermal runaway detection is performed on the battery in the charging and swapping cabinet to obtain a thermal runaway detection result, including: Perform voltage analysis and / or current analysis based on battery information within a preset time period to obtain voltage analysis results and / or current analysis results of the batteries in the charging and swapping cabinet; The thermal runaway detection result is determined based on the temperature change trend and severity of the change, as well as the voltage analysis result and / or the current analysis result.

[0051] Specifically, the above process of performing thermal runaway detection on the battery in the charging and swapping cabinet according to the temperature change trend and the severity of the change, as well as the battery information within a preset period of time, and obtaining the thermal runaway detection result specifically includes the following steps: First, the batteries in the charging and swapping cabinet can be analyzed based on the battery information during this period. Specifically, a voltage analysis can be performed on the battery to analyze whether its voltage is stable, whether it fluctuates greatly, or whether there is an abnormal increase, etc., so as to obtain a voltage analysis result; or a current analysis can be performed on the battery to analyze the change in the battery current to determine whether it fluctuates abnormally, so as to obtain a current analysis result; and voltage analysis and current analysis can also be performed simultaneously to obtain voltage analysis results and current analysis results, which are not specifically limited in the embodiments of the present invention.

[0052] Subsequently, the thermal runaway detection result can be determined by combining the temperature change trend and severity of the change, as well as the voltage analysis results and / or current analysis results, that is, the results obtained from the analysis of the temperature information and the battery information are integrated to obtain the thermal runaway detection result.

[0054] Specifically, the process of performing voltage analysis and / or current analysis based on the battery information within the preset time period to obtain the voltage analysis result and / or current analysis result of the battery in the charging and swapping cabinet may specifically include: Since the battery information is mainly divided into two aspects, namely the battery management system of the battery management system and the battery charging information, that is, including the battery management information and the battery charging information, therefore, when performing analysis based on the battery, the two aspects can be analyzed separately to obtain the analysis results of the two aspects of information on voltage and / or current.

[0055] In detail, the battery voltage analysis and / or battery current analysis can be performed based on the battery management information in the battery information during this period to obtain the battery voltage analysis results and / or battery current analysis results; that is, the battery voltage and / or current can be analyzed through the battery management information to determine whether the battery voltage has an abnormal increase and / or the current fluctuation is large during the operation of the charging and swapping cabinet, thereby obtaining the battery voltage analysis results and / or battery current analysis results.

[0056] At the same time, charging voltage analysis and / or charging current analysis can be performed based on the battery charging information to obtain charging voltage analysis results and / or charging current analysis results; that is, the battery charging information can be used to analyze the voltage and / or current of the battery during charging to determine whether the voltage and / or current of the battery during charging follows a specific charging curve, whether there are abnormal fluctuations, or whether it exceeds a specified range, to obtain charging voltage analysis results and / or charging current analysis results.

[0057] After that, the voltage analysis result and / or current analysis result of the battery in the charging and swapping cabinet can be determined by combining the battery voltage analysis result and / or battery current analysis result, as well as the charging voltage analysis result and / or charging current analysis result. That is, the analysis results of the above two aspects of information in terms of voltage and current can be combined to evaluate the thermal runaway risk of the battery. For example, if multiple analysis results indicate abnormalities, it can be determined that there is a high probability of thermal runaway.
