Abstract

The invention provides a multi-pack parallel mutual charging control circuit, a control method and an electric tool, wherein the multi-pack parallel mutual charging control circuit is used to perform multi-pack parallel mutual charging control on a battery module including a plurality of parallel battery packs, The multi-pack parallel charging control circuit includes: a battery pack detection unit, the battery pack detection unit is used to detect the working parameters of each battery pack; a control unit, the control unit is connected with the battery pack detection unit, and the control unit obtains according to the detection of the battery pack detection unit The operating parameters of the battery pack control the parallel connection or disconnection of the battery pack with other battery packs. According to the multi-pack parallel and mutual charging control circuit of the embodiment of the present invention, the working parameters of the battery pack are detected by the battery pack detection unit, and the parallel connection or disconnection of the battery pack and other battery packs is controlled by the control unit according to the working parameters, which can avoid the battery pack. Packages are recharged over a range of operating conditions.

Description

technical field [0001] The invention relates to the technical field of electric tool preparation, in particular to a multi-pack parallel and mutual charging control circuit, a control method and an electric tool. Background technique [0002] With the improvement of people's quality of life, higher requirements for the living environment are also put forward. As a kind of landscaping machinery, electric lawn mowers are widely used in the trimming and finishing of urban street gardens, street green belts, and home garden lights and green spaces. [0003] In the field of electric lawn mowers, lithium batteries have been more and more widely used due to their excellent new energy in many aspects. However, limited by the battery life of single battery pack lawn mowers, multi-battery lawn mowers are becoming more and more popular. At present, the mainstream multi-battery pack lawn mower control is manual switching of battery packs. When one set of battery packs is lit and disc...
