Both-side-wire-outlet battery system with USB (Universal Serial Bus) interface and electric quantity display

Abstract

The invention relates to a both-side-wire-outlet battery system. The battery system comprises two batteries, a both-side wire outlet manner is adopted, and a battery box correspondingly adopts a semi-box buckle form, so that the use requirements that batteries need on-site charging, are not conveniently taken out or are limited to the space are met; a charging connector and a power supplying connector which are communicated with a charging plug and a power supplying plug of a shell end cover are arranged in the battery box, the electrical connection between the batteries and the battery box is very convenient, and the connection between the batteries and the battery box is achieved by only correctly loading the batteries into the battery box; all the batteries in the box share a power supply output port, and a voltage stabilizing module or voltage splitting module is connected between the power supply output port and the power supplying connector as required, so that due to such a structure, a power supplying system can simultaneously supply power to different loads according to the power consuming demands of the different loads, thereby avoiding the problems of wiring complexity and low stability and reliability caused due to the fact that battery systems comprising a plurality of batteries do not have a unified power supply output port.

Description

technical field [0001] The invention belongs to the field of power supply systems, and relates to a power supply system comprising one or more battery modules. Background technique [0002] At present, there is more than one electrical load on many electrical equipment, and these loads often have different voltages, and some of them also require voltage stabilization. The power supply system includes multiple battery modules. In actual use, each battery module must be individually connected to the corresponding load to supply power for it, and there is no unified power supply port. The problems with this structure are complex wiring, low stability and low reliability. Contents of the invention [0003] In order to solve the technical problems of complex wiring, low stability and reliability of the current power supply system, the present invention provides a battery system with a USB interface, a power display, and two outlets on both sides that is easy to use, simple to ...
