Problems solved by technology

[0002] In the garden machinery and power tool industry, electric tools usually have a rated working voltage, that is, the whole machine with different voltage platforms needs battery packs with different voltage platforms to provide power. Therefore, different battery packs need to be prepared to adapt to different rated voltages. Power tools with working voltage increase the cost of use and cause waste of resources

Abstract

The invention provides an electricity storage device, comprising N energy units equal in voltage and capable of providing at least three output voltages. N is a composite number; each of the N energyunits is equally divided into a plurality of energy unit modules; each energy unit module has a module inner control portion. In the initial state, the module inner control portions connect the energyunits in the same energy unit module in parallel. Different plugs are connected with the electricity storage device in order to allow the electricity storage device to output one of at least three output voltages to an electric tool using the electricity storage device. Therefore, the applicable range of the electricity storage device is widened, and the application cost is reduced.

Description

technical field [0001] The invention relates to the technical field of electric tools, in particular to an electric energy storage device and an electric tool using the electric energy storage device. Background technique [0002] In the garden machinery and power tool industry, electric tools usually have a rated working voltage, that is, the whole machine with different voltage platforms needs battery packs with different voltage platforms to provide power. Therefore, different battery packs need to be prepared to adapt to different rated voltages. Power tools with working voltage increase the cost of use and cause waste of resources. [0003] In view of this, it is necessary to design an improved electric energy storage device and an electric tool using the electric energy storage device to solve the above problems. Contents of the invention [0004] The object of the present invention is to provide an electric energy storage device capable of providing at least three ...
