[0056] As the core component of new energy vehicles, new energy power batteries are not only directly related to the performance and safety of vehicles, but also closely related to the overall situation of environmental protection and efficient utilization of resources. From the selection of materials to the innovation of technologies and then to the ensuring of safety performance, the development of new energy power batteries is a process with both multi-dimensional challenges and opportunities.

[0057] The safety characteristics of power batteries have gradually become the focus of attention of the general public. During the use of power batteries, a battery management system (BATTERY MANAGEMENT SYSTEM), also known as BMS, is usually set up to monitor the temperature of the power battery and balance its internal temperature through relevant control strategies to avoid excessive temperature or large temperature difference, so that the power battery works in the best working temperature range. At the same time, it can also monitor the parameter status of the power battery such as voltage and current, prevent overcharging and over-discharging, and extend the service life of the power battery.

[0058] As mentioned in the background art, the battery management system includes devices such as temperature sensors and voltage sensors to monitor information such as the temperature and voltage of the power battery. Since the space for installing the power battery in the vehicle is limited, one temperature sensor is usually used to monitor the cells of multiple power batteries through circuit wiring.

[0059] However, when the battery management system detects an abnormal temperature of the power battery, it is necessary to check each cell of multiple power batteries one by one, resulting in low work efficiency.

[0060] Based on the above technical problems, the embodiments of the present application provide a cell, a battery pack and a vehicle. In this technical solution, the cell includes a cell body and a cover structure. The cover structure includes a cover body and a monitoring component. The monitoring component can monitor the temperature of the cell body. By arranging the cover body to cover the cell body and providing an avoidance groove on the side of the cover body facing the cell body for the installation of the monitoring component, the cover body, the monitoring component and the cell body are assembled into a whole, thereby enabling a single cell to have the ability to monitor temperature, enabling the battery management system to accurately obtain the temperature information of each cell. When abnormal temperature information appears, there is no need to check each cell one by one, improving the work efficiency of the battery management system.

[0061] It should be noted that Figures 1 to 5 schematically shows a simplified schematic diagram of each component in the cell, the battery pack and the vehicle. The specific structures of the remaining components in the cell, the battery pack and the vehicle are not limited to Figures 1 to 5 the illustration of.

[0062] The following will be a detailed description of the embodiments of the present application in conjunction with the drawings and specific embodiments:

[0063] Referring to Figure 1 as shown, the embodiments of the present application provide a cell, including: a cell body 100 and a cover structure.

[0064] The cover structure includes: a cover body 200 and a monitoring component 300. The cover body 200 covers the cell body 100.

[0065] The cover body 200 can be detachably connected to the cell body 100 through buckles, bolts, etc., or can be connected to the cell body 100 by spot welding or other means. The connection method between the cover body 200 and the cell body 100 is a mature technology in the related field, and the embodiments of the present application will not elaborate on this.

[0066] An avoidance groove is provided on the side of the cover body 200 facing the cell body 100, and the monitoring component 300 is located in the avoidance groove.

[0067] By arranging the cover plate body 200 to cover the battery cell body 100, and providing an avoidance groove on one side of the cover plate body 200 facing the battery cell body 100 for the installation of the monitoring component 300, the cover plate body 200, the monitoring component 300 and the battery cell body 100 are assembled into a whole, thereby realizing the ability of a single battery cell to monitor temperature, enabling the battery management system to accurately obtain the temperature information of each battery cell. When abnormal temperature information appears, there is no need to check each battery cell one by one, improving the working efficiency of the battery management system.

[0068] The monitoring component 300 includes a control member 310 and a monitoring member 320 arranged on the control member 310. The monitoring member 320 is electrically connected to the control member 310, and the monitoring member 320 is used to collect the temperature of the battery cell body 100.

[0069] The control member 310 is used to receive the temperature information of the battery cell body 100 collected by the monitoring member 320 and transmit the temperature information of the battery cell body 100 to the battery management system. Here, the battery management system can be a battery management system independent of the vehicle battery pack, and of course it can also be a battery management system integrated in the battery pack. The specific structure and installation position of the battery management system in this application embodiment are not limited.

[0070] The control member 310 is a PCB (Printed Circuit Board) in the related field. It can be understood that the PCB can achieve reliable electrical connections between electronic components and is convenient for integrating electronic components such as resistors and controllers. The specific structure of the control member 310 in this application embodiment is not limited.

[0071] In the above implementation manner, by arranging the monitoring component 300 on the cover plate body 200, the temperature information of the battery cell body 100 is directly transmitted to the monitoring member 320, and the control member 310 can transmit the temperature information of the battery cell body 100 to the battery management system, enabling the battery management system to accurately obtain the temperature information of each battery cell body 100 and improving the working efficiency of the battery management system.

[0072] Specifically, the monitoring member 320 is an NTC (Negative Temperature Coefficient) thermistor sensor. Of course, the monitoring member 320 can also be any other temperature sensor. The specific structure of the monitoring member 320 in this application embodiment is not limited.

[0073] In a possible implementation manner, referring to Figure 1 、 Figure 3 、 Figure 4 and Figure 5As shown, it further includes a connection wire row 500. The connection wire row 500 connects the battery cell body 100 and the monitoring component 300. Specifically, the connection wire row 500 connects the battery cell body 100 and the control component 310 in series, so that the battery cell body 100 supplies power to the control component 310 through the connection wire row 500.

[0074] In the specific implementation of the above embodiment, a voltage sensor (not shown in the figure) may also be provided on the control component 310, and the voltage of the battery cell body 100 is monitored through the connection wire row 500. With such a setting, it can not only enable the independent power supply of the control component 310 in the cover plate structure of the battery cell body 100, but also monitor information such as the voltage of the battery cell body 100.

[0075] In a possible implementation manner, referring to Figure 4 and Figure 5 as shown, the avoidance groove includes a first installation groove 210, and the control component 310 is located in the first installation groove 210.

[0076] In the above embodiment, a first installation groove 210 is opened on the cover plate body 200 for installing the control component 310, which can make full use of the space, facilitate the integration of the cover plate body 200 and the control component 310. At the same time, the control component 310 is arranged on the side of the cover plate body 200 facing the battery cell body 100, which is equivalent to the control component 310 being arranged between the battery cell body 100 and the cover plate body 200. The cover plate body 200 and the battery cell body 100 jointly play a role in protecting the control component 310 and extending the service life of the control component 310.

[0077] In a possible implementation manner, in order to further facilitate integration, the side of the cover plate body 200 facing the battery cell body 100 further has a second installation groove 220. The second installation groove 220 is communicated with the first installation groove 210, and the connection wire row 500 is located in the second installation groove 220. The cover plate body 200 and the battery cell body 100 jointly protect the connection wire row 500, and at the same time facilitate the integration of the cover plate body 200 and the connection wire row 500.

[0078] In a possible implementation manner, referring to Figure 1 and Figure 2 as shown, in order to facilitate the monitoring component 320 to collect the temperature information of the battery cell body 100, it further includes a heat conduction component 400. The heat conduction component 400 includes a heat conduction pad 410 and a heat conduction sheet 420.

[0079] The heat conduction pad 410 is used to abut against the battery cell body 100. The heat conduction pad 410 is connected to the heat conduction sheet 420, and the heat conduction sheet 420 is connected to the monitoring component 320, so that the temperature of the battery cell body 100 is transmitted to the monitoring component 320 through the heat conduction pad 410 and the heat conduction sheet 420.

[0080] Here, the heat-conducting pad 410 is a pure heat-conducting silica gel sheet. The heat-conducting pad 410 has good flexibility and excellent insulation. The pure heat-conducting silica gel sheet has self-adhesion. On the premise of ensuring stable contact between the heat-conducting pad 410 and the battery cell body 100, it can also adapt to various irregular heat-generating surfaces, so that the contact surface between the heat-conducting pad 410 and the battery cell body 100 is well filled, which helps heat conduction and enables the temperature of the battery cell body 100 to be transmitted to the heat-conducting sheet 420 more accurately.

[0081] It should be noted that in the related art, a unique high-temperature resistant film or a heat-pressed aluminum-plastic film is provided on the outer surface of the battery cell body 100. At the contact position between the heat-conducting pad 410 and the battery cell body 100, the corresponding position on the battery cell body 100 needs to be polished so that the heat-conducting pad 410 is in direct contact with the battery cell body 100, improving the accuracy of temperature monitoring.

[0082] The heat-conducting sheet 420 is at least one or a combination of two or more of a metal nickel sheet, a metal aluminum sheet, and a graphite sheet. As long as the temperature of the heat-conducting pad 410 can be transmitted to the monitoring component 320 through the heat-conducting sheet 420, the specific structure and material of the heat-conducting sheet 420 are not limited in the embodiments of the present application. When specifically implemented, reasonable selection can be made by comprehensively considering costs, processing difficulty, etc.

[0083] In the above embodiment, the temperature of the battery cell body 100 is first transmitted to the heat-conducting pad 410, and the heat-conducting pad 410 transmits the temperature to the monitoring component 320 through the heat-conducting sheet 420. Here, it should be noted that the monitoring component 320 can obtain the temperature of the battery cell body 100 through the heat-conducting component 400, without the monitoring component 320 directly contacting the battery cell body 100, avoiding damage to electronic components such as the monitoring component 320, and moreover, the reasonable installation of the monitoring component 320 can be realized, making full use of the space.

[0084] In a possible implementation manner, in order to ensure the stable connection between the monitoring component 320 and the heat-conducting sheet 420, the heat-conducting sheet 420 and the monitoring component 320 are bonded by a heat-conducting adhesive 430. The heat-conducting adhesive 430 can be a silicone heat-conducting curing adhesive, which can make the heat-conducting sheet 420 and the monitoring component 320 bonded stably and does not affect the temperature transmission at the same time.

[0085] In a possible implementation manner, the cover structure further includes an antenna assembly (not shown in the figure). The antenna assembly is disposed on the control component 310 and is electrically connected to the control component 310. The antenna assembly is used for communicating with the battery management system to transmit the temperature information of the battery cell body 100 received by the control component 310 to the battery management system.

[0086] In the above embodiment, the antenna assembly can be at least one of a PCB monopole antenna, a PCB patch antenna, and a Bluetooth antenna, so that the PCB circuit board can communicate with the battery management system via Bluetooth or wirelessly.

[0087] The cover body 200 has at least two mounting holes 230, which are used to correspond to the pole columns of the battery cell body 100, and the pole columns of the battery cell body 100 are used to be inserted into the mounting holes 230. After the cover body 200 is connected to the battery cell body 100, the pole columns of the battery cell body 100 are correspondingly inserted into the mounting holes 230, and both ends of the connection wire row 500 are located in the mounting holes 230. In this way, after the cover body 200 is connected to the battery cell body 100, both ends of the connection wire row 500 will contact the pole columns of the battery cell body 100 respectively to realize power supply. This setting method helps to improve the assembly efficiency of the cover body 200 and the battery cell body 100.

[0088] Furthermore, an explosion-proof hole 240 and a liquid injection hole 250 are also formed on the cover body 200. To ensure the safety of the battery cell body 100, an explosion-proof valve is usually added to the battery cell body 100, and the formed explosion-proof hole 240 corresponds to the explosion-proof valve, which improves the safety of the battery cell body 100, and the liquid injection hole 250 can facilitate the injection of the electrolyte into the battery cell body 100. Of course, the specific shape and structure of the explosion-proof hole 240 and the liquid injection hole 250 are mature technologies in the related field and can be flexibly set according to design needs. The embodiments of the present application do not limit the structures of the explosion-proof hole 240 and the liquid injection hole 250.

[0089] The embodiment of the present application also provides a battery pack, which includes a battery pack body and a plurality of any one of the battery cells mentioned in the above embodiments. The specific structure of the battery cell has been described above and will not be elaborated here.

[0090] With such a setting, the battery pack can independently have the function of monitoring the temperature of the battery cells inside it, and can eliminate the limitation of many wire harnesses, which is convenient for assembly.

[0091] The embodiment of the present application also provides a vehicle, which includes a vehicle body and a battery pack arranged on the vehicle body. The battery pack is the battery pack with the function of independent temperature monitoring mentioned above and will not be elaborated here. Of course, the specific structure of the vehicle body in the present application is not limited, and it can be a new energy vehicle, a new energy train, etc. It can enable the battery management system of the vehicle body to accurately monitor the temperature information of the battery cells in each battery pack, which helps to improve the working efficiency of the battery management system.

[0092] The implementation principle of a battery cell, a battery pack, and a vehicle according to an embodiment of the present application is as follows: The cover structure includes a cover body 200 and a monitoring component 300. The monitoring component 300 includes a control member 310 and a monitoring member 320 disposed on the control member 310. The control member 310 is disposed on the cover body 200. The monitoring member 320 is electrically connected to the control member 310. The monitoring member 320 is used to collect the temperature of the battery cell body 100. The control member 310 is used to receive and transmit the temperature of the battery cell body 100 collected by the monitoring member 320. By disposing the monitoring component 300 on the cover body 200, the temperature information of the battery cell body 100 is directly transmitted to the monitoring member 320, and the control member 310 can transmit the temperature of the battery cell body 100 to the battery management system, so that the battery management system can accurately obtain the temperature information of each battery cell body 100. After the temperature anomaly information appears, it is not necessary to check each battery cell body 100 one by one, improving the working efficiency of the battery management system.
