Description

Technical Field

[0001] This utility model relates to the field of energy storage technology, and in particular to a battery pack structure that facilitates the maintenance of internal electrical components. Background Technology

[0002] With the widespread application and continuous development of new energy equipment, the requirements for the performance and reliability of battery packs are increasing. In many scenarios, such as electric vehicles and energy storage systems, the stable operation of the battery pack, as a key energy supply component, is crucial. The battery pack structure can be referenced in Chinese invention patent application number CN201711226915.4, entitled "Battery Pack and Vehicle Having the Same." However, traditional battery pack structures often require complex disassembly and reassembly operations when maintaining internal electrical components. Removing the top cover may involve multiple steps and complex operations; slight carelessness can damage internal components or wiring. This is not only time-consuming and labor-intensive but also prone to damaging the battery pack and electrical components during operation, increasing maintenance costs and reducing equipment lifespan. During disassembly, accidental contact with high-voltage circuits may occur, leading to electric shock and other safety accidents. Simultaneously, the market demand for efficient equipment maintenance and rapid fault repair is constantly increasing. In addition to tool and time costs, additional costs are required to replace parts if damage occurs during disassembly. Utility Model Content

[0005] The top cover and side walls have maintenance windows;

[0006] A ring-shaped bracket is installed around the maintenance window on the outer wall of the top cover;

[0007] The BMS is covered outside the maintenance window and is detachably connected to the first bracket via connectors.

[0008] Furthermore, the annular bracket is locked to the top cover by the first fastener.

[0009] Furthermore, the outer wall of the top cover is provided with a lock hole, and the annular bracket is locked to the lock hole by screws.

[0010] Furthermore, the connector includes a press-fit screw and a nut. The press-fit screw is mounted on an annular bracket and is connected to the nut after passing through a connection hole on the BMS.

[0011] Furthermore, the side wall of the top cover is provided with an installation port, and a connector panel is provided at the installation port, which is connected to the BMS.

[0012] Furthermore, it also includes a housing, which is locked to the top cover and the connector panel respectively.

[0017] The beneficial effects of this utility model are as follows: A battery pack structure that facilitates the maintenance of internal electrical components. Since the internal electrical components, such as fuses, require maintenance, a maintenance window is provided on the side wall of the upper cover. Because the upper cover is made of plastic and nuts cannot be directly inserted, a BMS cover is installed on the outside of the maintenance window via a ring bracket. Subsequent maintenance of fuses and other electrical components can be achieved simply by removing the BMS.

This battery pack structure, which facilitates the maintenance of internal electrical components, improves maintenance efficiency. The front-facing maintenance method allows maintenance personnel to quickly and directly access the components that need to be handled, eliminating the need for cumbersome disassembly steps, thus greatly shortening maintenance time and improving work efficiency. Secondly, it reduces maintenance costs. The convenient front-facing maintenance reduces the potential damage to components caused by complex disassembly and reassembly, lowering material costs during the repair process. At the same time, efficient maintenance reduces labor costs and enhances the reliability and stability of the equipment. Timely and convenient maintenance can more effectively prevent and resolve potential problems, reduce the failure of the entire battery pack or even related equipment caused by electrical component failures, reduce equipment downtime, improve equipment availability, and enhance the stability of equipment operation.
