[0023] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0024] Please refer to the following: Figures 1 to 4 This utility model discloses an uninterruptible power supply (UPS), which includes a power supply body 20 and multiple temperature-monitoring battery modules 10, all of which are mounted on the power supply body 20. Each temperature-monitoring battery module 10 includes a module body, a battery management system 4, and a temperature sensor. Both the temperature sensor and the battery management system 4 are mounted on the module body, and the temperature sensor is electrically connected to the battery management system 4. The temperature sensor collects temperature information from the module body and transmits it to the battery management system 4. This design, through the electrical connection between the temperature sensor and the battery management system 4, achieves real-time accurate monitoring and multi-level collaborative management of the battery module 10 temperature: the temperature sensor directly collects the battery module 10 temperature information and transmits it to the battery management system 4, enabling rapid response to temperature anomalies (such as overheating or underheating). The battery management system 4 triggers dynamic regulation (such as activating cooling / heating or fuse protection), effectively reducing the risk of thermal runaway.

[0025] In some embodiments, the main body of the module includes a housing 1, a battery pack, and a fuse 3. The battery pack and fuse 3 are both mounted on the housing 1. The temperature sensors include a first temperature sensor 51 for collecting temperature information of the battery pack, a second temperature sensor 52 for collecting temperature information of the positive electrode of the battery pack, a third temperature sensor 53 for collecting temperature information of the negative electrode of the battery pack, a fourth temperature sensor 54 for collecting temperature information of the positive electrode of the fuse, and a fifth temperature sensor 55 for collecting temperature information of the negative electrode of the fuse. With this design, the temperature sensors cover key locations such as the battery pack, the positive / negative electrodes, and the positive and negative electrodes of the fuse 3, enabling full-link monitoring of potential hazards such as internal temperature rise of the battery 21, abnormal electrode contact (such as increased resistance due to poor soldering / corrosion), and precursors to overcurrent blowing of the fuse 3. By comparing temperature data from multiple nodes, local overheating or abnormal temperature differences can be accurately identified. Combined with the dynamic control of the battery management system 4 (such as fuse protection or charge / discharge current limiting), thermal runaway and circuit failures can be effectively prevented. This multi-dimensional temperature acquisition architecture significantly improves the safety and fault warning capabilities of the battery 21 system.

[0026] In some embodiments, the battery pack includes four batteries 21 connected in series, with adjacent batteries 21 connected by conductive sheets 22. All four batteries 21 are mounted on the outer casing 1. Four first temperature sensors 51 are respectively mounted on each of the four batteries 21 to collect temperature information. A second temperature sensor 52 collects temperature data from the positive electrode of the first battery, and a third temperature sensor 53 collects temperature data from the negative electrode of the last battery. This design, using a series topology of four batteries 21 and three conductive sheets 22, and precise positioning of the positive and negative electrodes of the first and last batteries, forms a non-redundant series current transmission path. Independent temperature sensors are installed on the surfaces of the four batteries 21, enabling single-cell thermal runaway early warning. Compared to traditional centralized monitoring schemes, the abnormal temperature rise detection time can be shortened to within 2 seconds.

[0027] Specifically, four batteries 21 are spaced apart on the casing 1, and four first temperature sensors 51 are respectively disposed on the sidewalls of the four batteries 21. This design, through the coordinated design of the spaced arrangement of the four batteries 21 and the distributed temperature sensors on the sidewalls, achieves precise temperature monitoring and rapid thermal response at the individual cell level. Combined with the stress buffering of the spaced structure and the non-intrusive installation characteristics of the sensors, it improves energy density, reduces the rate of thermal runaway accidents in the battery pack, and effectively extends cycle life, achieving a dual breakthrough in high safety and structural stability.

[0028] In some embodiments, the battery pack is provided with a positive electrode connector 23 and a negative electrode connector 24. A second temperature sensor 52 is disposed on the positive electrode connector 23 for collecting temperature information of the positive electrode of the battery pack, and a third temperature sensor 53 is disposed on the negative electrode connector 24 for collecting temperature information of the negative electrode of the battery pack. As can be seen from the above, the battery pack includes four batteries 21 connected in series, with the positive electrode connector 23 disposed on the positive electrode side of the first battery and the negative electrode connector 24 disposed on the negative electrode side of the last battery.

[0029] In some embodiments, the battery module 10 further includes two first connection terminals 6 and a manual maintenance switch 7. The two first connection terminals 6 are disposed on the housing 1 and electrically connected to the battery pack. The fuse 3 is disposed on the manual maintenance switch 7. The manual maintenance switch 7 is provided with two second connection terminals 71 electrically connected to the fuse 3. The manual maintenance switch 7 is detachably connected to the housing 1 and the two second connection terminals 71 are detachably plugged into the two first connection terminals 6 respectively. A fourth temperature sensor 54 is disposed on one of the first connection terminals 6 for collecting temperature information of the positive electrode of the fuse. A fifth temperature sensor 55 is disposed on the other first connection terminal 6 for collecting temperature information of the negative electrode of the fuse. This design approach, through the introduction of a detachable manual maintenance switch 7, significantly improves safety and operational efficiency: In terms of safety, the physical disconnection mechanism of the manual maintenance switch 7 can quickly cut off the high-voltage circuit, and combined with the built-in fuse 3, it provides dual protection, effectively avoiding the risk of electric shock or short circuit during maintenance; in terms of economy, the modular design supports partial replacement, and the standardized interface simplifies the operation process, greatly reducing downtime; in terms of system scalability, the flexible plug-in structure adapts to multiple battery 21 modules, is compatible with mass production, and reserves space for intelligent monitoring upgrades. Simultaneously, precise on / off control reduces standby power consumption, providing technical support for the efficient operation and maintenance, safety protection, and future intelligent upgrades of the battery 21 system.

[0030] Furthermore, to secure the first connection terminal 6 to the housing 1, the battery module 10 also includes two connectors 8. The two connectors 8 are disposed on the housing 1, and the two first connection terminals 6 are respectively disposed on the two connectors 8. A fourth temperature sensor 54 is disposed on one of the connectors 8, and a fifth temperature sensor 55 is disposed on the other connector 8. With this design, the connectors 8 provide rigid support for the first connection terminal 6 and also prevent stress during insertion and removal from directly acting on the housing 1 body, thus improving its resistance to vibration and mechanical impact.

[0031] In some embodiments, in order to allow timely observation of temperature information during use, the power supply unit is equipped with a display 201, the battery management system 4 is electrically connected to the display 201 and sends temperature information to the display 201, and the display 201 is used to display the temperature information.

[0032] In some embodiments, the power supply unit 20 is also equipped with an alarm device. The battery management system 4 is electrically connected to the alarm device and is used to send alarm information to the alarm device when the temperature of the module body exceeds a preset value. The alarm device then sounds an alarm based on the alarm information. This design approach utilizes a direct communication architecture between the battery management system 4 and the alarm device to trigger a response mechanism when the module body temperature exceeds a preset threshold, providing real-time and accurate alarms.

[0033] This utility model provides an uninterruptible power supply (UPS) that includes a battery module 10 capable of monitoring temperature. The battery module 10 comprises a main body, a battery management system 4, and a temperature sensor. Both the temperature sensor and the battery management system 4 are located on the main body, with the temperature sensor electrically connected to the battery management system 4. The temperature sensor collects temperature information from the main body and transmits it to the battery management system 4. This design, through the electrical connection between the temperature sensor and the battery management system 4, enables real-time, accurate monitoring and multi-level collaborative management of the battery module 10's temperature. The temperature sensor directly collects temperature information from the battery module 10 and transmits it to the battery management system 4, allowing for rapid response to temperature anomalies (such as overheating or underheating).
