Abstract

The invention discloses an omniseal battery pack, which can effectively solve the problem that the existing battery is easy to be incapable of normally working due to shaking or dampness. The omnisealbattery pack comprises two or more than two battery cells and seal shells, the battery cell is arranged in the shell, the inner wall of the shell is provided with a protective layer, and the shell isalso internally provided with a protective circuit. The invention has the advantages that the shell is omnisealed, uses the protective layer internally, so that the battery pack has good shake-proofand damp-proof performances and is convenient to carry and use, and the overall appearance is more beautiful, the internal protective circuit can better protect the battery cell from being overchargedor over-discharged, and the situation of short circuit from occurring, and can prolong the service life of the battery cell.

Description

Technical field [0001] The invention relates to a fully sealed battery pack. Background technique [0002] A battery pack composed of two or more cells can power any cordless device, especially cordless power tools in the field of power tools. Therefore, the battery pack must often move with these cordless devices, which is inevitable during the movement. Vibration can easily loosen internal components and cause damage to the battery, or in a relatively humid environment, the battery cell can easily become damp and make it unable to work normally. Summary of the invention [0003] The purpose of the present invention is to provide a fully sealed battery pack, which can effectively solve the problem that the existing battery pack is easily unable to work normally due to vibration or moisture. [0004] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: a fully sealed battery pack, including two or more battery ...
