Problems solved by technology

However, due to the limited battery capacity, when using a DC lawn mower, if the lawn area is large, a single battery pack or even two battery packs cannot complete the mowing work. time will be extended
It is known that in order to solve the above problems, users usually need to equip multiple battery packs, or even match a multi-head charger to charge multiple battery packs at the same time, but the cost of using multiple battery packs will be greatly increased for users.

Abstract

A direct-current system for direct-current tools comprises a charger and at least two lithium battery packs. The lithium battery packs can be used for alternately discharging to the tools circularly so as to realize uninterrupted power endurance. The direct-current system has the remarkable advantage that the uninterrupted power endurance system is realized in a low-cost and safe way.

Description

technical field [0001] The invention relates to a direct current system, in particular to a direct current system for garden electric tools. Background technique [0002] At present, battery-powered garden tools are recognized by more and more users due to their environmental protection and cordless portability, such as DC electric lawn mowers. However, due to the limited battery capacity, when using a DC lawn mower, if the lawn area is large, a single battery pack or even two battery packs cannot complete the mowing work. Time will be extended. It is known that in order to solve the above problems, users usually need to equip multiple battery packs, or even match a multi-head charger to charge multiple battery packs at the same time, but the cost of using multiple battery packs will be greatly increased for users. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a DC system, which can prolong the discharge time of t...
