The utility model patent that China Patent No. ZL200720194333.8 discloses a kind of " preventing the self discharge charger ".Though this patent can be carried out boost charge at the electric weight of storage battery self discharge loss, and can control charge capacity and be unlikely to make accumulator super-charge, this patent not to solve because the battery sulfuration problem that the long-time charging of little electric current causes.Therefore, also there is tangible deficiency in this patent.

The utility model content

The purpose of this utility model is to provide a kind of employing depolarising charging technique, avoided little electric current to charge for a long time defective that accumulators brings, can keep the capacitance of storage battery for a long time and guarantee not can accumulators to bring overcharging, can not draw storage battery vulcanization yet, make storage battery remain optimum state, and the depolarising charger of high efficiency, prolongation battery shelf life that energy consumption is little.

The technical solution of the utility model is achieved in that

A kind of depolarising charger that prolongs battery shelf life, its characteristics are to comprise power circuit module, central control circuit module, charging circuit module, discharge circuit module, energy-storage module, recharge circuit module and electronic switch module, wherein

The power circuit module is made up of transformer and DC power supply circuit, and this power circuit module provides work required power supply for whole charging device;

The central control circuit module has the IC main control chip of control program and peripheral auxiliary circuit thereof to constitute by subsection, this central control circuit module is electrically connected with the control input end of charging circuit module, discharge circuit module respectively, with control charging circuit module, discharge circuit module to storage battery charge, discharging action, realize the process of depolarising charging;

Electronic switch module is provided with several battery charge connectivity ports, connects simultaneously for some batteries, and the input of this electronic switch module is electrically connected with the output of charging circuit module, discharge circuit module respectively;

The output of energy-storage module and discharge circuit module is electrically connected, so that the battery discharging electric weight is stored;

The input and central control circuit module, the energy-storage module that recharge circuit module are electrically connected, the input of its output and electronic switch module is electrically connected, with under the central control circuit module controls, the electric weight that energy-storage module collect is stored, through recharge circuit module, electronic switch module recharges accumulators.

Technical advantage of the present utility model:

Owing to adopt by power circuit module, central control circuit module, charging circuit module, discharge circuit module, energy-storage module, recharge the depolarising charger that circuit module and electronic switch module constitute, this device by the unified accurately control of central control circuit module down, utilize charging circuit module, discharge circuit module alternately storage battery to be carried out charge and discharge, realize the depolarising charging process of storage battery, avoided long-time little electric current continuously storage battery to be charged and cause the problem of the sulfuration of accumulator plate.This device can remedy the capacitance loss that self discharge causes, and removes sulfuration, improves battery quality; The storage period that has prolonged battery effectively, also prolonged simultaneously the useful life of battery, makes storage battery remain best performance state.And, by energy-storage module, recharge the electric energy storage of circuit module can also be with battery discharging the time, again under the central control circuit module controls, recharge in the storage battery with selecting a good opportunity, thereby can reduce the energy consumption of this device widely, improve utilization rate of electrical, reduced the operating cost of enterprise.
