[0002] Lift battery pack is a battery assembly used in lift equipment. Its main function is to provide power for the lift. During the operation of the lift, such as lifting or lowering heavy objects such as cars, electric energy is needed to drive the motor to operate, thereby driving the hydraulic system or mechanical transmission system to work. The battery pack is a key component to provide this electric energy. It generally contains multiple battery cells. These battery cells can be different types such as lead-acid batteries and lithium batteries. For example, the battery cells inside the lithium battery pack are usually connected together in series and / or parallel to achieve the required voltage and capacity. It also includes a battery management system (BMS). The main function of BMS is to monitor the status of the battery, such as the battery's voltage, current, temperature and other parameters. Taking the lithium battery pack as an example, the BMS can prevent the battery from overcharging and over-discharging, ensure that the battery operates within a safe operating range, and extend the battery life. At the same time, it can also balance the power of each battery cell to prevent damage to individual battery cells due to overcharging or discharging.

[0014] The adapter frame cooperates with the installation port, which not only limits the battery pack body to prevent it from shaking and shifting during the installation process, but also has a unique three-section structural design, namely, the upper section is a concave arc structure, the middle section is a vertical structure, and the lower section is an arc structure bent toward the center. The circumferential diameter of the lower end is smaller than that of the upper end. This can better guide the battery pack into the installation position and provide stable support and restraint during the installation process, further ensuring the stability of the installation.

[0015] The clear installation channel and adaptive structural design make the installation process clearer and more convenient. Installers can quickly and accurately complete the installation of the battery pack, which improves assembly efficiency, reduces labor costs, and is conducive to large-scale production operations.

[0016] Accurate and stable battery pack installation ensures the stability of the internal circuit connection of the battery pack, improves the charging and discharging performance and service life of the battery pack, while also improving the overall structural stability of the mounted equipment and reducing equipment failures and abnormal operations caused by battery pack installation problems.
