LM7806 formed full-automatic Nickel cadmium battery charging circuit diagram

Published:2011/5/9 0:16:00 Author:Crystal Liu | Keyword: full-automatic Nickel cadmium battery charging circuit

LM7806 formed full-automatic Nickel cadmium battery charging circuit diagram
The charging circuit uses fold point voltage method to charge the nickel cadmium battery . When the battery is plentiful, charge current will be reduced to 8mA automaticly, meanwhile light diode indicates charging end,so it can not produce the phenomenon of overcharge and Owe filling,thus prolong life of the Nickel cadmium battery.

Constant current & voltage lithium battery charger circuit

Published:2011/5/9 6:25:00 Author:Christina | Keyword: Constant current & voltage, lithium battery charger

This device is designed as one kind of constant current & voltage lithium battery charger circuit, the precision adjustable voltage regulator is composed of the Q1, R1, W1, TL431. The adjustable constant current circuit is composed of the Q2、W2、R2. The charging indicator circuit is composed of the Q3、R3、R4、R5 and LED. As the charged battery's voltage increases gradually, the charge current will be reduced gradually, when the battery is full, R4's pressure-drop will be decreased, and the Q3 cuts off, the LED turns off to ensure the battery is sufficient, please continue to charge the battery for 1-2 hours after the indicator light turns off, you need to install the heatsink on Q2 and Q3.
