A APPARATUS FOR RAPIDLY CHARGING THE NiCd/NiMH BATTERYS SERIALLY AND SIMULTANEOUSLY

摘要

The present invention, nickel can be charged rapidly at the same time a plurality of batteries of cadmium / nickel-hydrogen batteries serially rapidly simultaneously provides a filling device.; To this end, the present invention is described below, a plurality of charging with the microcomputer, PWM control, and, a battery charger and the battery voltage detection unit, respectively.; Further, with the battery charger, the comparator is at a high signal by the microcomputer are entered into non-reflective shear compared to the voltage of the inverting stage is set to 4V outputs a power supply voltage of 12V to the output terminal; Receiving a gate applied with the charging current supplied from the PWM control unit connected to the output terminal of the comparator and the resistance mediated drain, N-type MOSFET with a source connected to the contact point, and; Further included parts of the switch.; Furthermore, with the switch unit, and the NPN transistor with a base connected to a power supply voltage, an emitter and a collector connected to the resistor connected to the contact; And a base connected to the NPN transistor to the resistance parameter, and connected to the emitter resistance, and, with the collector connected to the contact and NPN transistor; Teuraenjiseuteogwa NPN and the base is connected to the resistance parameter, associated with the contact and the emitter is configured to include a PNP transistor having a collector connected to the contacts.; Accordingly, the present invention, the power loss is more than ever flew rapidly a leak current from the battery with little nickel cadmium / nickel-metal hydride batteries in series the same time it is possible to provide a filling device.
