Description

Intelligent superhigh speed charger

The utility model relates to a kind of charger, particularly is applicable to the intelligent super-quick charging motor of cadmium nickel (zinc-manganese) storage battery of video camera, portable phone one class mobile communication equipment.

Usually be that little electric current is long-time to charge in batteries, this is because storage battery is when being recharged, along with the increase of charging current, and the polarization reaction that inner generation is strong.This not only makes storage battery have little time to absorb the electric energy of charging, and makes unnecessary electric energy be converted into heat energy soon, and battery temp is risen rapidly, is to cause to cause permanent damage, and for this reason, the charging interval of normal charge device reaches 8-10 hour.External (as U.S. Mo Tuoluola company) quick charger of producing temperature rise and surface tension of utilizing computer to detect at any time to be filled storage battery, in time reduce charging current, make the unlikely damage of storage battery, increased charging current effectively, make the charging interval shorten to 1 and a half hours.But because circuit complexity, cost is very high, be difficult to large-scale popularization, this just makes our telephotography staff have only 20～40 minutes at a camera time (storage battery) in AC-less power place, generally also be no more than 45 minutes the continuous service time of portable phone mobile communication equipment, and the charging interval must be spent 8～10 hours (or 1 and a half hours), and the user feels very inconvenience.

At the present situation that present charger exists, a kind of large current charge that makes becomes the intelligent super-quick charging motor that possibility shortens the charging interval greatly thereby the purpose of this utility model is design.

The utility model can be realized above-mentioned purpose by following design feature, and it is by main power source, rectifying and wave-filtering, and control power supply, constant current charge switch, depolarizing switch, intelligent thick film and timing soft-touch control totally seven circuit constitute.Electric main is after the main power source step-down, through rectifying and wave-filtering, one the tunnel makes the control power supply, charge power supply is made on another road, deliver to the constant current charge switching circuit, the charging control impuls of exporting in the intelligence thick film piece is delivered to charge switch circuit, the control charge in batteries, and the depolarising of depolarization circuit control storage battery is delivered in depolarising pulse (being discharge pulse).Above-mentioned two kinds of circuit are all filled accumulator positive with quilt and are extremely joined, the positive pole of storage battery is received the detection input of thick film piece simultaneously, for detecting the situation of being filled storage battery at any time, the effect of cracked ends series diode displaying charging not, automatically red light and send warning flashes when storage battery is full of, charge power supply becomes little current impulse immediately, shuts down automatically when treating timer to the scheduled time, to guarantee the safety of storage battery.

Charge switch in this machine and depolarizing switch circuit are owing to adopted present state-of-the art intelligent high-power switch integrated package, the polarity effect that produces when in time eliminating charging, make large current charge become possibility, thereby shortened the charging interval greatly (only needing be full of in 10～15 minutes), and have self protective functions such as overheated, short circuit, be equipped with peripheral circuit, for television camera with and the mobile communication of portable phone class provide a kind of function admirable with storage battery, the convenient super-quick charging electrical equipment that is suitable for.

Below provide embodiment

Fig. 2 is an electrical schematic diagram

Main power circuit 1 is a switching power supply, the signal of 220V electric main after voltage stabilizing delivered to by diode D1-4, the current rectifying and wave filtering circuit 2 that capacitor C 1-2 forms, form charging voltage, its output signal is delivered to IC3(7812 respectively) the control power circuit 3 that constitutes and constant current charge switching circuit 4(T1 2N3055, T2,3 usefulness 9013 of T1-3 and IC1 formation, IC1 produces BTS412 with Siemens), the control power supply is given intelligent thick film circuit 6(ZLD-ICI) working power is provided, charging voltage is carried out constant current charge through the constant current charge switch to storage battery E.The depolarising pulse signal that the intelligence thick film circuit produces is delivered to by smart power switch ic chip 2(Siemens and is produced BTS412) the depolarizing switch circuit 5 that constitutes, make its charging the gap to storage battery depolarising (storage battery E is to big resistance R L instantaneous discharge during being the IC2 admittance), the charging control wave that produces is delivered to IC1, and 4 pin of IC are delivered to intelligent thick film circuit 22 pin with the bar fault detection signal.Intelligence thick film circuit 6 is independently developed a kind of secondary integrated circuits, form by charging pulse, depolarising pulse shaping, automatically identification, detect automatically, show automatically, report to the police automatically and formation such as " treatment " circuit, the positive pole of storage battery E except that with the constant current charge switching circuit with the depolarizing switch circuit links to each other, also link to each other with the detection input of intelligent thick film circuit, for detecting the situation of being filled storage battery at any time, cracked ends series LED 1～5 does not show the effect of charging.Automatic guide sound optical alarm circuit was indicated simultaneously and is sent chimes of doom by alarm BJ when storage battery was full of, and charging current becomes little current impulse immediately.Timer circuit 7 is by integrated circuit (IC) 4(NE555) constitute, be that typical monostable touches circuit.When hand soft-touch control sheet, high level, open circuit are sent in the circuit upset; After being timed to, low level is sent in upset automatically again, turn-offs intelligent thick film piece and shuts down, to guarantee the safety of storage battery.

The utility model is except that the charging interval is short, can also effectively prolong the useful life of storage battery, " treatment " storage battery (eliminating the memory effect of nickel cadmium cell) in spite of illness, the intelligent film piece of this machine can be discerned automatically new, old, " in spite of illness " storage battery different with depositing electric weight, and corresponding change charge and discharge control impuls, make quilt under the various states fill storage battery and all can reach the optimal charge effect, it is radiated the vigour of youth again.
