Description

Technical Field

[0001] This utility model relates to the field of lithium battery charging technology, specifically a lithium battery pack charging component. Background Technology

[0002] A lithium battery charging assembly is an electronic device used to manage the charging process of a lithium battery. It typically consists of a charger, a charging control circuit, a protection circuit, and a battery monitoring system. Its main function is to convert AC or DC power into voltage and current suitable for charging lithium batteries, ensuring that the charging process is safe, efficient, and does not damage the battery. The charging assembly usually includes battery protection functions to prevent overcharging, over-discharging, and overheating, thus extending battery life. In addition, the charging control circuit automatically adjusts charging parameters based on the current battery level to ensure the stability and safety of the charging process. The battery monitoring system monitors battery voltage, current, and temperature data in real time, providing necessary feedback to prevent safety issues caused by abnormal conditions.

[0003] In existing technologies, traditional lithium battery charging components, taking 18650 lithium batteries as an example, can typically only charge one 18650 battery at a time. This design results in low charging efficiency, especially in scenarios where multiple batteries need to be charged simultaneously. For example, in power tools, electric vehicles, or large-scale energy storage systems, multiple batteries are often used in parallel. However, traditional charging components cannot provide independent and optimized charging management for multiple batteries simultaneously, leading to extended charging times. At the same time, a single charging path may also increase energy loss during the charging process, thereby reducing overall charging efficiency. Therefore, traditional charging components have many shortcomings in terms of efficiency, intelligence, and safety when handling large-scale battery charging, limiting their application in multi-battery systems. Thus, there is an urgent need for a solution to these problems. Utility Model Content

Under the synergistic effect of the lower positioning grooves 205 and upper positioning grooves, the lithium battery bodies 4 are accurately positioned, ensuring that each battery can receive the current provided by the charging component 1.

[0024] Working principle: The charging assembly 1 consists of two supporting plates 101. At the ends of the supporting plates 101, arc-shaped plates 102 are connected to each other. The arc-shaped plates 102 are used to position the lithium battery body 4. The limiting grooves 103 on the supporting plates 101 are used to fix the conductive strips 104, which ensures smooth current flow and provides stable electrical contact. The conductive strips 104 in the limiting grooves 103 provide the current required for charging the lithium battery body 4. In addition, the supporting plates 101 are also connected to a protective cover 105, which can effectively protect the inside of the charging assembly 1 from external physical damage. At the same time, the first heat dissipation slots 106 on the cover ensure that the heat generated during charging can be dissipated in time to prevent overheating. The charging module 107 is connected to the power supply through the first conductive line 108 and transmits the current to each lithium battery body 4 through the second conductor 109. This design ensures that multiple batteries are charged at the same time, and each battery can receive a balanced current input, improving charging efficiency and reducing safety hazards.

[0025] The lower positioning component 2 is composed of a lower base plate 201, and the two supporting uprights 101 are slidably connected, allowing the lower positioning component 2 to be adjusted in position as needed. The sliding design between the lower base plate 201 and the charging module 107 makes the lower positioning component 2 easy to install and disassemble during use, facilitating maintenance. Multiple lower positioning grooves 205 provided on the lower base plate 201 provide a stable placement position for the lithium battery body 4. The arc-shaped inner wall of the lower positioning groove 205 fits tightly with the lithium battery body 4. At the same time, the first anti-slip particles 206 ensure that the battery will not shift due to vibration or other external forces. The lower positioning component 2 further enhances the thermal management during battery charging by setting a second heat dissipation slot 207, ensuring temperature stability during charging, reducing the risk of overheating, and extending battery life.

[0026] The upper positioning component 3 is connected to the bushing 202 of the lower positioning component 2 via a rotating shaft 301. The rotating shaft 301 allows the upper positioning component 3 to rotate around its axis. This design provides greater flexibility, allowing the component to be operated and adjusted without disassembly. The connecting lugs 302 at both ends of the upper positioning component 3 are fixedly connected to the upper base plate 303. The upper base plate 303 cooperates with the latch 204 on the lower positioning component 2 via a buckle 305 to firmly clamp multiple lithium battery bodies 4 in the positioning groove 306, ensuring that the battery maintains a stable position during charging and avoiding poor battery contact or charging failure due to positional displacement. The upper positioning component 3 also has multiple third heat dissipation slots 308 inside, which are designed to assist in heat dissipation, maintain stable temperature during charging, and avoid affecting charging efficiency and battery safety due to excessive temperature.

[0027] Multiple lithium battery bodies 4 are installed in the lower positioning groove 205 and the upper positioning groove 306. With the synergistic effect of the lower positioning groove 205 and the upper positioning groove, the lithium battery bodies 4 are precisely positioned, ensuring that each battery can receive the current provided by the charging component 1 and reducing electrical contact problems caused by position changes during charging. The first anti-slip particle 206 and the second anti-slip particle 307, through close contact with the outer wall of the lithium battery, further enhance the effect of preventing the battery from moving or sliding during charging, increasing the stability and safety of the charging process. Through this structural design, it can be ensured that each lithium battery body 4 can receive current input evenly during charging, avoiding the risks caused by charging imbalance.
