Abstract

The invention provides a multi-pack parallel mutual-charging control circuit, a control method and an electric tool. The multi-pack parallel mutual-charging control circuit is used for performing multi-pack parallel mutual-charging control on a battery module which comprises multiple parallel battery packs. The multi-pack parallel mutual-charging control circuit comprises a battery pack detectionunit and a control unit, wherein the battery pack detection unit is used for detecting working parameters of each battery pack; and the control unit is connected with the battery pack detection unit and controls parallel connection or disconnection of one arbitrary battery pack and other battery packs according to the working parameters, detected by the battery pack detection unit, of the arbitrary battery pack. According to the multi-pack parallel mutual-charging control circuit in the embodiment, the working parameters of the battery packs are detected through the battery pack detection unit, the control unit controls parallel connection or disconnection of the arbitrary battery pack and other battery packs according to the working parameters of the arbitrary battery pack, and thereforemutual charging of the battery packs exceeding a working condition range can be avoided.

Description

technical field [0001] The invention relates to the technical field of electric tool preparation, in particular to a multi-pack parallel 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 are placed on the living environment. As a kind of landscaping machinery, electric lawn mowers are widely used in the pruning and finishing of urban street gardens, street green belts, and family garden light green spaces. [0003] In the field of electric lawn mowers, lithium batteries have been more and more widely used due to their excellent new performance in many aspects. However, multi-battery lawnmowers are becoming more and more popular due to the limited battery life of single-battery lawnmowers. At present, the mainstream multi-battery pack lawn mower is controlled by manually switching battery packs. When one set of battery packs is lit and discharged, it is...
