In one embodiment, as shown in fig. 1, a temperature monitoring device 200 includes a connection line body 300, a temperature acquisition device 400, and a data processing device 500. As shown in fig. 2, one end of the connection wire body 300 is used to connect the positive electrode tab 112 of one battery cell 100. The other end of the connection wire body 300 is used to connect the negative electrode tab 114 of another battery cell 100. The battery is a battery pack formed by connecting two or more battery cells 100 in series. When the storage battery is used, the temperature change has obvious influence on performances such as internal resistance, cycle performance and the like, so the temperature of the storage battery needs to be monitored. The pole column on each storage battery monomer 100 is made of a metal material, has good heat conduction performance and is connected with the battery core, so that the temperature of the battery core inside the storage battery monomer 100 can be accurately reflected by monitoring the temperature of the pole column. In the present embodiment, the connection wire body 300 is a connection wire connecting the battery cells 100 in series. In order to monitor the temperature of the poles of the battery cell 100 in real time, a temperature acquisition device 400 and a data processing device 500 are integrated on the connection line body 300. The temperature acquisition device 400 is used for acquiring the temperature of at least one of the positive electrode pole 112 and the negative electrode pole 114. The temperature acquisition device 400 may be a temperature sensor, or may be a combination of a thermally conductive metal and a temperature sensor. The data processing device 500 is used for performing data processing on the data collected by the temperature collecting device 400 to monitor the temperature of the corresponding pole.
In the present embodiment, the temperature monitored by the temperature monitoring device 200 is the temperature of the anode post 114 connected to the temperature monitoring device 200. In general, a fault in the battery cell 100 often occurs at the negative electrode. Therefore, by monitoring the temperature of the negative electrode post 114, the battery can be timely maintained to ensure safety and extend the service life of the battery. For example, a control circuit may be integrated in the temperature monitoring device 200, and the control circuit immediately cuts off the power supply whenever the temperature measured by the temperature monitoring device 200 exceeds a preset temperature. In other embodiments, the temperature monitoring device 200 can also monitor the temperature of the positive electrode post 112 connected to the connection wire body 300. In addition, the data processing device 500 may be connected to an intelligent terminal through a data line or a wireless network, and the temperature of the corresponding pole monitored by the temperature monitoring device 200 may be displayed on the intelligent terminal. A display or the like may also be provided on the data processing device 500 so that a user can directly observe the temperature of the corresponding pole. In other embodiments, the connecting wire body 300 may be a connecting wire additionally provided.
In the temperature monitoring device 200, the connection wire body 300 is an electrical element for connecting the two battery cells 100 in series when the battery is powered. The temperature acquisition device 400 and the data processing device 500 are integrated in the connecting wire body 300, and the connecting wire body 300 can realize the functions of connecting two battery cells 100 in series and simultaneously can also monitor the temperature of the poles of the battery cells 100 in real time without manual operation in the whole process.
In one embodiment, as shown in fig. 1, the connection wire body 300 includes a connection wire head 310 and a connection wire body 320. The connecting wire terminals 310 are respectively disposed at two ends of the connecting wire body 300. In this embodiment, the structure of the connecting wire ends 310 at both ends of the connecting wire body 300 is the same. The connection wire terminals 310 at both ends of the connection wire body 300 are connected to the positive electrode tab of one battery cell 100 and the negative electrode tab of the other battery cell 100, respectively. The connection wire terminal 310 is provided therein with a fixing structure connected to a corresponding post of the battery cell 100. In the present embodiment, the connecting wire terminal 310 is provided therein with a mounting hole 312 fixedly fitted with the post of the battery cell 100. The corresponding pole is fixed at the mounting hole 312 by means of a gasket, riveting, screwing, etc. The cross-sectional shape of the post is not limited to a circular shape, and may be, for example, a square shape, a hexagonal prism shape, or the like. The connection wire ends 310 at both ends of the connection wire body 300 are connected by the connection wire body 320.
In an embodiment, the connecting wire ends 310 and the connecting wire body 320 are integrally injection-molded and compression-molded, that is, the connecting wire ends 310 and the connecting wire body 320 at two ends of the connecting wire body 300 are in an integral structure from the external appearance, so that the connection reliability and fastening between the integral connecting wire body 300 and the pole of the battery cell 100 are ensured.

The positive electrode pole 112 of one storage battery cell 100 and the negative electrode pole 112 of the other storage battery cell 100 are respectively fixed at the threaded holes at the two ends of the connecting wire body 200 through bolts, so that firm and sufficient connection between the poles of the storage battery cell 100 and the temperature monitoring device 200 is ensured.
In one embodiment, as shown in fig. 1, the connecting wire body 320 includes a conductive layer 322 and an outer layer 324 covering the conductive layer 322. The conductive layer 322 may be a metal wire made of a conductive material, or a wire coated with an insulating material on the outer layer of the metal wire. The outer layer 324 is a layer of insulating material. One end of the conductive layer 322 is connected to the temperature acquisition device 400, i.e., one end of the conductive layer 322 extends out of the outer layer 344 to be connected to the temperature acquisition device 400, and the rest of the conductive layer 322 is located inside the outer layer 344. The other end of the conductive layer 322 is connected to the data processing device 500. The conductive layer 322 is used for transmitting the data acquired by the temperature acquisition device 400 to the data processing device 500. It can be understood that the pole temperature data measured by the temperature acquisition device 400 is a physical quantity, that is, the temperature acquisition device 400 represents the corresponding pole temperature data by a physical quantity such as a resistor, and then transmits the physical quantity such as the resistor representing the pole temperature data to the data processing module 500 through the conductive layer 324. The data processing module 500 converts the physical quantity into temperature data of the corresponding pole, so as to monitor the temperature data of the corresponding pole in real time. In other embodiments, an alarm device and a contrast module may also be provided. The comparison module compares the measured temperature of the pole with a preset temperature. When the temperature of the pole exceeds the preset temperature, the alarm module carries out voice prompt or short message prompt and the like to inform a user, or directly cuts off the power supply and the like. In one embodiment, the conductive layer 324 is a copper core twisted pair. The copper core twisted pair can effectively reduce signal interference and is beneficial to reducing cost. The copper core twisted pair is arranged in the insulating material, and is integrated with the inside of the connecting wire body 420, so that the overall aesthetic property of the temperature monitoring device 200 is ensured, and the safety is further enhanced.
The temperature acquisition device 400 may be a contact type temperature sensor or a non-contact type temperature sensor. Optionally, a contact temperature sensor is used. The temperature sensor is used for measuring the temperature of the corresponding pole. The temperature sensor is in sufficient contact with the pole to ensure that the measured temperature data is more accurate. In one embodiment, as shown in fig. 3, the temperature acquisition device 400 is a sheet metal. Optionally, the outer surface of the connecting wire end 310 is made of an insulating material, and the mounting hole 312 is made of a metal material. The metal sheet is disposed in the mounting hole 312 and directly contacts the pole to measure the temperature of the corresponding pole. It will be appreciated that the predetermined temperature collection point 412 in fig. 3 is located on the insulating layer of the connecting wire terminal 310, so that the metal sheet is required to be connected to the conductive layer 322 in fig. 2 after extending to the temperature collection point 412 outside the mounting hole 312. The temperature acquisition point 412 is not limited to the location in fig. 3. The conductive layer 322 and the metal sheet are integrally injection-molded and compression-molded, so that the aesthetic property of the temperature monitoring device 200 is not affected, and the tightness of the integral connection of the conductive layer is ensured.
In one embodiment, the metal sheet is integrally formed with the wire ends 310. It can be appreciated that the metal sheet is integrally formed with the connection wire end 310 in the mounting hole 312, and when the pole passes through the mounting hole 312 in the connection wire end 310, the metal sheet can be fully contacted with the corresponding pole, so that the temperature signal of the corresponding pole can be reliably collected.
In one embodiment, as shown in FIG. 4, the data processing apparatus 500 includes a housing 512 and a processor (not shown). The processor is disposed within the housing 512. The center of the housing 512 is a hollow structure. The connecting wire body 320 passes through the central hole 514 of the housing 512 so that the processor is powered by the self-induced current of the connecting wire body 300. In order to more intuitively see the structure of the housing 512 of the data processing apparatus 500, a schematic perspective view of the housing 512 is shown in fig. 5. In this embodiment, when no current flows in the main circuit of the battery, there is no temperature change in the battery post temperature, and no temperature data detection may be performed at this time. At this time, the connection wire body 300 passing through the central hole 514 of the data processing apparatus 500 does not generate a self-induced current, and the data processing apparatus 500 is not powered, and the data processing apparatus 500 stops operating. The connecting wire body 300 integrates a temperature detection function, realizes the collection and data transmission of the corresponding pole temperature of the battery cell 100, integrates integrated application, namely, forms temperature collection, transmission and treatment integration, and does not need other accessories. The self-induction current is used for supplying power, an external power supply is not needed, the problem that the internal temperature of the storage battery is not monitored is effectively solved, the aims of integrity and safety and reliability of on-line monitoring of the storage battery are achieved, accurate testing of the temperature of the pole is achieved, the monitoring capability of the storage battery is improved, and the operation safety of a storage battery pack is improved. The housing 512 is fixedly connected with the connecting wire body 320, so that relative sliding between the data processing device 500 and the connecting wire body 300 is avoided, friction is reduced, and the service life of the device is prolonged. In view of the convenience of installing the temperature monitoring device 200 when the two battery cells 100 are connected, the housing 512 may be fixed to the middle position of the connection wire body 320. Optionally, the housing 512 is integrally formed with the connecting wire body 320.
In one embodiment, the processor employs a highly integrated microchip and is disposed within the housing 512. The microchip has smaller volume and ultra-low power consumption, ensures that the generated self-induced current can supply power for the chip, reduces the overall size of the temperature monitoring device 200, and does not occupy too large volume.
In one embodiment, as shown in fig. 2, a battery assembly includes more than two battery cells 100. The positive electrode of each battery cell 100 is connected to a positive electrode post 112, and the negative electrode is connected to a negative electrode post 114. The battery assembly also includes the temperature monitoring device 200 described above. The number of battery cells 100 in the battery assembly in the present embodiment is not limited to the number in fig. 1. In other embodiments, the temperature monitoring device 200 may not be provided with the mounting hole 312, but be provided integrally with the corresponding pole, i.e., the temperature monitoring device 200 is integral with the battery.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
