[0002] A lithium battery is a type of battery that uses lithium metal or lithium compounds as the positive and negative electrode materials. It stores and releases electrical energy by the movement of lithium ions between the positive and negative electrodes during charging and discharging. Lithium batteries have high energy density, long cycle life, and light weight, and are widely used in portable electronic devices, power tools, electric vehicles, and other fields.

During use, especially in summer or in direct sunlight, the ambient temperature can be high. The lithium battery itself generates heat during operation, particularly during charging and discharging. Excessive heat can degrade battery performance, shorten its lifespan, and may even pose safety risks. Utility Model Content

Excessive temperature will lead to a decrease in the performance and lifespan of the lithium battery body, and may even cause safety problems.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a lithium battery with a power indicator module, including a lithium battery body, an LCD screen is provided on one side of the lithium battery body, and a cooling and heat dissipation device is provided on the outer surface of the lithium battery body. The cooling and heat dissipation device can cool one side of the semiconductor refrigeration chip after it is energized, and then conduct heat through copper sheet to contact the surface of the lithium battery body to achieve the effect of cooling and heat dissipation.

[0006] Preferably, the cooling and heat dissipation device includes two semiconductor refrigeration chips. A detachable device is provided between one side of each of the two semiconductor refrigeration chips and the two sides of the lithium battery body. Several copper plates are symmetrically fixedly connected to one side of each semiconductor refrigeration chip, wherein one side of the copper plates is in close contact with the outer surface of the lithium battery body, and the several copper plates on the two semiconductor refrigeration chips are distributed in an alternating manner.

[0007] The effects achieved by the aforementioned components are as follows: By incorporating a cooling and heat dissipation device, existing lithium battery modules typically have an internal battery management system for ease of use. This system monitors data such as voltage and current of the lithium battery module, calculates the remaining charge using a power estimation algorithm, and displays the charge status to the user on an LCD screen on one side, helping the user understand the charging status of the lithium battery module in real time. During the use of the lithium battery module, the semiconductor cooling chip can be energized to cool one side, and then conduction occurs through several copper plates, resulting in heat exchange with the surface of the lithium battery module, thus reducing the surface temperature of the lithium battery module. This achieves the effect of cooling the lithium battery module during use, preventing overheating that could lead to performance degradation, extending its lifespan, and reducing safety hazards during use.

[0008] Preferably, extension rods are symmetrically fixedly installed at both ends of the copper sheet, and one side of the extension rod is fixedly installed on one side of the semiconductor cooling chip.

[0009] The effect achieved by the above components is that by setting the extension rod, the contact area between the two ends of the copper sheet and the semiconductor cooling chip can be increased, the temperature can be transferred to the copper sheet more quickly to make it cool down, and the cooling effect can be improved.

[0010] Preferably, a limiting mechanism is provided between one end of the outer surface of the copper sheet and one side of the lithium battery body. The limiting mechanism includes a first U-shaped block, wherein both ends of the first U-shaped block are fixedly connected to one side of the lithium battery body; and a rubber block, wherein one side of the rubber block is fixedly installed in the inner wall of the first U-shaped block, and one end of the outer surface of the copper sheet is inserted into the rubber block and the inner wall of the first U-shaped block.

[0011] The effect achieved by the above components is as follows: by setting a limiting mechanism, when the semiconductor cooling chip and several copper sheets are fixedly installed on the outer surface of the lithium battery body, several copper sheets can be inserted into the inner wall of the first U-shaped block and the rubber block to limit and support one end of the copper sheets, so that they are not easy to shake during use.

[0012] Preferably, a limiting block is symmetrically fixedly installed on one side of the first U-shaped block, and the limiting block is fixed at an angle on one side of the entrance of the first U-shaped block.

[0013] The effect achieved by the above components is that by setting the limiting block, the area at the entrance of the first U-shaped block can be increased, making it easier for one end of the copper sheet to be quickly aligned with the inner wall of the first U-shaped block and inserted, thus facilitating installation.

[0014] Preferably, the detachable device includes two card holders, one side of which is fixedly mounted on both sides of the semiconductor cooling chip. A sliding hole is symmetrically provided on one side of each card holder. A second U-shaped block is symmetrically fixedly mounted on both sides of the lithium battery body. A locking hole is provided on one side of the inner wall of each second U-shaped block. The two ends of the card holder are respectively inserted into the inner walls of the two opposing second U-shaped blocks. A locking block is also included, with one end slidably connected to the inner wall of the sliding hole and the other end inserted into the inner wall of the locking hole. A spring is also included, with both ends fixedly mounted on one side of the inner wall of the locking block and the sliding groove, respectively.

[0015] The effect achieved by the above-mentioned components is as follows: by setting up a detachable device, when it is necessary to maintain or replace the semiconductor cooler, the locking block can be manually slid to one end in a certain position in the inner wall of the sliding hole, causing the spring to contract and pull one end out of the locking hole. Then, by holding the semiconductor cooler and pulling it to one end, the locking bracket can be pulled out from the inner wall of the second U-shaped block, so that the semiconductor cooler can be removed from the lithium battery body for easy replacement and maintenance.

[0016] Preferably, the card holder has trapezoidal cross-sections at both ends, and the size of the end of the card holder away from the semiconductor cooling chip is smaller than the size of the other end.

[0017] The effect achieved by the above components is that by making the size of the end of the card holder away from the semiconductor cooling chip smaller than the size of the other end, the area of ​​one end of the card holder can be reduced, making it easier to quickly align with and install the inner wall of the second U-shaped block.

[0018] Preferably, a telescopic rod is fixedly installed on one side of the inner wall of the sliding hole, and one end of the telescopic rod passes through the inner wall of the spring and is fixedly connected to one side of the locking block.

[0019] The effect achieved by the above components is that by setting up the telescopic rod, the inner wall of the spring can be supported and reinforced, making it less prone to damage during use.

[0020] The beneficial effects of this utility model are:

[0021] By setting up a cooling and heat dissipation device, when the lithium battery body is in use, the semiconductor cooling chip can be energized to cool one side. Then, through several copper plates, heat is conducted to the surface of the lithium battery body, resulting in heat exchange and reducing the surface temperature of the lithium battery body. This achieves the effect of cooling the lithium battery body during use, making it less likely for the lithium battery body to overheat and cause battery performance degradation, thus improving its service life and reducing safety hazards during use.

[0030] Figures 1-4 The lithium battery shown includes a lithium battery body 1, an LCD screen 2 on one side of the lithium battery body 1, and a cooling and heat dissipation device 3 on the outer surface of the lithium battery body 1. The cooling and heat dissipation device 3 can cool one side of the semiconductor refrigeration chip 31 after it is energized, and then conduct heat through the copper sheet 32 ​​to contact the surface of the lithium battery body 1 to achieve the effect of cooling and heat dissipation.

[0031] Figures 1-4The cooling and heat dissipation device 3 shown includes two semiconductor cooling chips 31. A detachable device 4 is provided between one side of the two semiconductor cooling chips 31 and the two sides of the lithium battery body 1. Several copper plates 32 are symmetrically fixedly connected to one side of the semiconductor cooling chip 31. One side of the copper plates 32 is in close contact with the outer surface of the lithium battery body 1. The several copper plates 32 on the two semiconductor cooling chips 31 are distributed in an alternating manner. For ease of use, existing lithium battery bodies 1 typically have an internal battery management system (BMS) that monitors voltage, current, and other data. The BMS calculates the remaining charge using a power estimation method and displays the charge status on a side-mounted LCD screen 2, allowing users to monitor the charging progress in real time. During use, the semiconductor cooling chip 31 can be energized to cool one side. Heat is then conducted through several copper plates 32, exchanging heat with the surface of the lithium battery body 1 and reducing its surface temperature. This cooling effect prevents overheating and performance degradation, extending battery life and reducing safety hazards. Extension rods 33 are symmetrically fixed to both ends of the copper plates 32, with one side of each rod fixed to one side of the semiconductor cooling chip 31. The extension rods 33 increase the contact area between the copper plates 32 and the semiconductor cooling chip 31, allowing for faster heat transfer and improved cooling efficiency.

[0032] Figures 1-4 A limiting mechanism 34 is provided between the outer surface of one end of the copper sheet 32 ​​and one side of the lithium battery body 1. The limiting mechanism 34 includes a first U-shaped block 341, both ends of which are fixedly connected to one side of the lithium battery body 1; and a rubber block 342, one side of which is fixedly installed in the inner wall of the first U-shaped block 341. The outer surface of one end of the copper sheet 32 ​​is inserted into the rubber block 342 and the inner wall of the first U-shaped block 341. By providing the limiting mechanism 34, when the semiconductor cooling chip 31 and several copper sheets 32 are fixedly installed on the outer surface of the lithium battery body 1, several copper sheets 32 can be inserted into the inner wall of the first U-shaped block 341 and the rubber block 342 to limit and support one end of the copper sheet 32, making it less prone to shaking during use. A limiting block 343 is symmetrically fixedly installed on one side of the first U-shaped block 341, and the limiting block 343 is fixed at an angle on one side of the entrance of the first U-shaped block 341. By setting the limiting block 343, the area at the entrance of the first U-shaped block 341 can be increased, making it easier for one end of the copper sheet 32 ​​to quickly align with the inner wall of the first U-shaped block 341 and insert it, thus facilitating installation.

[0033] Figures 1-4The detachable device 4 shown includes two card holders 43, one side of which is fixedly installed on both sides of the semiconductor cooling chip 31. A sliding hole 44 is symmetrically opened on one side of the card holder 43. A second U-shaped block 41 is symmetrically fixedly installed on both sides of the lithium battery body 1. A locking hole 42 is opened on one side of the inner wall of the second U-shaped block 41. The two ends of the card holder 43 are respectively inserted into the inner wall of the two opposing second U-shaped blocks 41. A locking block 46, one end of which is slidably connected to the inner wall of the sliding hole 44, and the other end is inserted into the inner wall of the locking hole 42. A spring 45, the two ends of which are fixedly installed on one side of the inner wall of the locking block 46 and the sliding groove. When maintenance or replacement of the thermoelectric cooler 31 is required, the locking block 46 can be manually slid to one end in the inner wall of the sliding hole 44 to a certain position, causing the spring 45 to contract and pull one end out of the locking hole 42. Then, the thermoelectric cooler 31 can be held and pulled to one end, which can drive the locking bracket 43 out of the inner wall of the second U-shaped block 41, so that the thermoelectric cooler 31 can be removed from the lithium battery body 1 for easy replacement and maintenance.

[0034] Figures 1-4 The card holder 43 shown has trapezoidal cross-sections at both ends, with the end of the card holder 43 furthest from the thermoelectric cooler 31 being smaller than the other end. By making the end of the card holder 43 furthest from the thermoelectric cooler 31 smaller than the other end, the area of ​​one end of the card holder 43 can be reduced, facilitating quick alignment and installation onto the inner wall of the second U-shaped block 41. A telescopic rod 47 is fixedly installed on one side of the inner wall of the sliding hole 44, with one end of the telescopic rod 47 penetrating the inner wall of the spring 45 and fixedly connected to one side of the card block 46. By setting the telescopic rod 47, the inner wall of the spring 45 can be supported and reinforced, making it less prone to damage during use.

[0035] Working principle: For ease of use, existing lithium battery bodies 1 are usually equipped with a battery management system. The battery management system monitors data such as voltage and current of the lithium battery body 1, calculates the remaining power using a power estimation method, and displays the power status to the user on an LCD screen 2 on one side, helping the user to understand the charging status of the lithium battery body 1 in real time. During the use of the lithium battery body 1, the semiconductor cooling chip 31 can be energized to cool one side. Then, through several copper plates 32, heat is conducted to the surface of the lithium battery body 1, resulting in heat exchange and reducing the surface temperature of the lithium battery body 1. This achieves the effect of cooling the lithium battery body 1 during use, making it less likely to overheat and cause battery performance degradation, thus improving service life and reducing safety hazards during use.

[0036] When maintenance or replacement of the thermoelectric cooler 31 is required, the locking block 46 can be manually slid to one end in the inner wall of the sliding hole 44 to a certain position, causing the spring 45 to contract and pull one end out of the locking hole 42. Then, the thermoelectric cooler 31 can be held and pulled to one end, which can drive the locking bracket 43 out of the inner wall of the second U-shaped block 41, so that the thermoelectric cooler 31 can be removed from the lithium battery body 1 for easy replacement and maintenance. Similarly, the thermoelectric cooler 31 can also be fixedly installed on the lithium battery body 1.
