Abstract

The present application provides a battery-powered device, including one or a plurality of battery packs connected in parallel; each battery pack includes a battery box provided with a first electrode and a second electrode on the casing, and the battery box There are more than 2 batteries connected in series and a safety control module in the inner package; the first electrode is connected to the outlet of the safety control module, and the entrance of the safety control module is connected to the remaining battery of the first battery connected in series. One electrode is connected, and the remaining electrode of the last battery is connected to the second electrode; the safety control module includes a module casing and a charging anti-backflow unit and a load anti-backflow unit packaged in the module casing; the first electrode It is connected with one end of the load or charger, and the second electrode is connected with the other end of the load or charger. Based on the solution of the preferred embodiment of the present application, the quality of a single battery pack can be guaranteed to be better, and the mutual circulation between the battery packs can be prevented from damaging the battery life.

Description

technical field [0001] The present application relates to the technical field of batteries, and in particular, relates to a battery-powered device. Background technique [0002] With the increasing shortage of global energy and environmental protection issues, electric drives (such as electric vehicles) have become the focus of industrial development in various countries. Taking electric vehicles as an example, the bottleneck of its development is mainly the battery problem, and the safety and performance of the battery pack are among the more important issues. The existing battery pack is composed of a large number of single cells connected in series and in parallel. Since the flow of the current passing through each single cell in the battery pack is different, it will cause unevenness in the long-term use of the single cell. After repeated charging and discharging , There will be performance differences among the single cells in the battery pack, which is prone to local ...
