[0002] As an important component of modern power tools, the design, function and performance of power tool battery packs directly affect the overall use effect of power tools. However, in the existing technology, the design of power tool battery packs often has some shortcomings.

[0003] First of all, the power tool battery packs on the market often lack flexibility in structural design. Traditional battery packs usually adopt a fixed integrated design, which makes it difficult to replace or repair the internal components of the battery pack individually. This not only increases maintenance costs, but also in actual use, once a component fails, the entire battery pack may need to be replaced, resulting in a waste of resources.

[0004] Secondly, the interface design of existing power tool battery packs is relatively simple. Most battery packs are only equipped with one power interface for connecting power tools for charging or powering, which cannot meet the diverse needs for power interfaces in different scenarios. For example, when multiple devices need to be powered at the same time or different types of interfaces are required for charging and discharging, existing battery packs may not be able to meet the needs.

[0005] Based on this, the applicant proposed an electric tool battery pack to solve the above technical problems. Utility Model Content
