Abstract

The invention provides a battery pack, a tool system and a charging system. The battery pack comprises a shell assembly, a battery pack accommodated in the shell assembly and a control assembly electrically connected with the battery pack, wherein the control assembly is rotatably arranged and is provided with at least three target areas, when the control assembly rotates to a first target area, the battery pack outputs a first voltage value, when the control assembly rotates to a second target area, the battery pack outputs a second voltage value, when the control assembly rotates to a thirdtarget area, the battery pack outputs a third voltage value, the first voltage value is smaller than the second voltage value, and the second voltage value is smaller than the third voltage value. Compared with the prior art, the battery pack is advantaged in that the battery pack is in butt joint with connecting pieces in different target areas through rotation of the control assembly, series-parallel connection state switching of all the battery cell modules in the battery pack is achieved, then the output voltage of the battery pack is changed, and adaptability of a tool system with the battery pack is improved.

Description

technical field [0001] The invention relates to the technical field of battery packs, in particular to a battery pack, a tool system and a charging system. Background technique [0002] In the garden machinery and power tool industries, tools with different rated voltages usually need to be powered by battery packs with different rated voltages, which increases the types and costs of battery packs. [0003] In view of this, it is necessary to design an improved battery pack, tool system and charging system to solve the above problems. Contents of the invention [0004] The purpose of the present invention is to provide a battery pack, a tool system and a charging system capable of quick switching and output of three voltages. [0005] In order to achieve the above object, the present invention provides a battery pack, comprising a housing assembly, a battery pack accommodated in the housing assembly, and a control assembly electrically connected to the battery pack, the b...
