Intelligent charging maintenance box for lithium battery and control system

Abstract

The invention discloses an intelligent charging maintenance box for a lithium battery. The intelligent charging maintenance box comprises a box body, and the box body is provided with an AC input interface socket and a plurality of battery slot areas. Each battery slot area is provided with a battery port corresponding to the lithium battery; the AC input interface socket is connected with an AC power filter; and the AC power supply filter is connected with an AC / DC power supply module. The AC / DC power supply module is connected with the DC / DC power supply module and the charging circuit. Thecharging circuit is connected with a battery port, the battery port is further connected with a discharging circuit and a battery voltage and current sampling circuit, the charging circuit, the discharging circuit and the battery voltage and current sampling circuit are all connected with a microcomputer controller, the microcomputer controller is further connected with a state indicating circuit,and the state indicating circuit is connected with an LED indicating lamp located on the box body. Compared with the prior art, the lithium battery has a battery charging function and a full-automatic discharging maintenance function, so that the battery loss of the lithium battery caused by battery maintenance overdischarge is avoided, excessive investment of human resources is avoided, and theworking efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of charging boxes, in particular to a lithium battery intelligent charging maintenance box and a control system. Background technique [0002] The capacity, service life, and charge retention capacity of lithium batteries need to be tested by charging or discharging maintenance of lithium batteries according to the prescribed procedures, and the storage requirements of lithium batteries: the power of lithium batteries should be kept at about 70% of the nominal capacity, and every It needs to be charged once every 6 months. Although there are different types of chargers on the market, they can meet the basic requirements of lithium battery charging. About 70% of the lithium battery maintenance is completed, and such lithium battery maintenance equipment is very rare. And at the same time, the maintenance equipment for 16 lithium batteries is even rarer. At present, in the storage of lithium batteries, the l...

Problems solved by technology

[0003] Aiming at the above-mentioned technical problems in the related art, the present invention proposes a lithium battery intelligent charging maintenance box, which solves the current full-automatic maintenance function of the lithium battery from charging to discharging, thereby avoiding the need for manual operation of the lithium battery discharge, and at the same time continuously Monitor the discharge voltage of the lithium battery to avoid damage to the battery due to over-discharge of the lithium battery, resulting in high loss rate in battery maintenance, large consumption of human resources and low work efficiency. It can charge 16 lithium batteries at the same time and realize the lithium battery Full-automatic maintenance function from charging to discharging, with charging, discharging maintenance, voltage measurement, performance testing and other functions at the same time, which improves work efficiency
