Description

Technical Field

[0001] The utility model relates to the technical field of battery packs, and in particular to a multifunctional battery pack. Background Art

[0002] With the rapid development of the power tool industry, high-performance, high-reliability battery packs have become an indispensable core component of power tools. Traditional power tool battery packs mainly focus on providing stable and long-lasting power support for power tools. The design emphasis is often placed on battery capacity, discharge efficiency and safety, but often ignores the diverse needs that users may encounter during actual use. Therefore, with the increasing application scenarios of power tools and the increasing demand of users for the versatility of equipment, the functional limitations of traditional battery packs have gradually become apparent.

[0003] In many practical application scenarios, users not only need power tools to complete specific work tasks, but also hope that the battery pack can have more flexible and wider applicability. For example, when working or exploring outdoors, users may hope that the battery pack can not only power the power tools, but also serve as a mobile power source to charge portable electronic devices such as mobile phones, flashlights, and cameras to ensure smooth communication and continuous operation of the equipment.

[0004] Currently, if users want to charge other devices, they can only carry other mobile power supplies with them. If the battery pack can provide an additional discharge interface and be used as a temporary mobile power supply, it will greatly improve the user experience. And if it can meet the simultaneous charging of two or more devices, the battery pack can cope with more complex application scenarios.

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