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

摘要

The present invention provides a nickel-cadmium (NiCd) or nickel metal hydride (NiMH) nickel cadmium / nickel-hydrogen battery rapid charging apparatus in series to simultaneously charge the plurality of battery cells at the same time in series.; The present invention, the microprocessor (1) and, PWM control unit (2) and, the battery charger 3 and the battery size detecting unit 4 and the battery voltage detecting unit 5, a plurality of charging section (CB1~CBn) with each in the battery in series simultaneous rapid charging apparatus configured by having, as the battery charger (3), the microcomputer (1) is applied through from the terminal (SW-1) resistors (R11) to the charge control signal applied through the receiving base , connected to the ground terminal and the emitter, and resistor NPN transistor (Q11) having a collector connected to a power supply voltage to the (R12, R13) parameters; The resistor (R12, R13) as connected to the base and connected to the power supply voltage to the resistor (R12) parameters, PNP transistor (Q12) having an emitter connected to the power source voltage to said resistor (R12) in parallel between; Resistance contact as (R14) connected to a gate, a drain, and, a resistor (R15) in parallel with receiving applying a charge current (BATT +) is applied from the PWM control unit (2) connected to a collector of said PNP transistor (Q12) parameters N-type MOSFET (Q13) having a source connected to the (a2); A diode (D11), the charge current (+ BATT) supplied from the PWM control unit (2) applied to the anode side; The battery charge terminal connected to the cathode end and between the more and (a2) of the diode (D11) (P11, P12; P14, P13), and; Doedoe configuration comprising a terminal (P15, P16) coupled between said terminal (P13) and a contact (a2); While the charge a battery inserted in each charging section (CB1~CBn) at the same time in series, when the microcomputer 1 is to recognize the full charge of the battery inserted into the battery charger (3), the charge control signal is a high-level signal wherein the above is applied to the battery charger (3) with Sikkim turns on the NPN transistor (Q11) and said PNP transistor (Q12) and, N-type MOSFET (Q13) end the charging at the battery charger (3) by applying is applied through a charge current (BATT +) is the N-type MOSFET (Q13) with the following charging section that from the PWM control unit (2), characterized in that to control the charging of each unit cell individually.
