Abstract

The invention provides an electrical energy storage device. The electrical energy storage device comprises N energy units; each of the N energy units has a voltage of nV, N is a composite number, andthe number of submultiples is k. An equal number of energy units in the N energy units are optionally connected in different series-parallel combinations to output k different output voltages. An electric tool using the electrical energy storage device is cooperated with the electrical energy storage device by using a plug so that the electrical energy storage device outputs one of k different output voltages to the electric tool.

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 complete machine of different voltage platforms needs electric energy storage devices of different voltage platforms to provide power, so different electric energy storage devices need to be prepared to adapt Electric tools with different rated working voltages 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 providi...
