Abstract
The invention discloses a output balancer of rechargeable accumulator battery group. It is composed of circuit for detecting end voltage, photo-electric coupling circuit, pulse-duration modulation control circuit, power drive circuit, switch transformer as well as rectification and filter circuit. Above circuits are cascaded and encapsulated in a module. Wiring pole on the module can connect to monocase accumulator or group of accumulator battery. The invention can prevent obsolescence of group of accumulator battery in advanced from performance difference of monocase accumulator so as to prolong the service life.
Description
The present invention relates to a kind of servicing unit of rechargeable battery group, is a kind of balance of voltage element.
For the rechargeable battery group, because cell can form the difference of performances such as capacity, internal resistance in process of production, the performance difference of cell is tending towards obvious in battery pack, the battery that indivedual or several capacity are on the low side is meeting formation overdischarge phenomenon in various degree in the battery power discharge process, goes round and begins again and will cause battery pack to damage or the lost of life.
The object of the present invention is to provide a kind of output balancer for rechargeable accumulator unit that can prevent effectively that battery pack from causing whole Battery pack to be scrapped in advance because of the cell performance difference.
Technical solution of the present invention is:
A kind of output balancer for rechargeable accumulator unit, comprise the final pressure testing circuit, the final pressure testing circuit connects the photoelectricity coupling circuit, connect pulse-width modulation (PWM) control circuit behind the photoelectricity coupling circuit, control circuit for pulse-width modulation connects power driving circuit, power driving circuit is connected with switch transformer, and switch transformer connects current rectifying and wave filtering circuit.
Above-mentioned each circuit package in a module, the wiring utmost point that dress is connected with battery pack and cell on the module.
Advantage of the present invention is: when battery power discharge; when being lower than voltage protection point as monomer battery voltage; balancer work; make cell voltage continually and steadily on voltage protection point; and all the other batteries as usual discharge all reach the protection point voltage until all cell voltages; thereby can prevent effectively that battery pack from scrapping in advance because of the cell performance difference causes whole Battery pack, prolong the useful life of battery pack.
