Charge controller circuit Lead acid and NiCd batteries will last a long time if they are operated within the proper charge and discharge voltages. A charge controller circuit is a necessity for preventative battery over-charge. Conversely, a low circuit voltage disconnects (LVD) Prevents excessive battery discharge. The voltage comparator circuit Consists of U2, to which standard 5 volts regulator is used as a voltage reference, wired as a comparator U1a, and VR1 to provide a voltage divider to set point for the low voltage shutoff. When the battery voltage is above the threshold provides a positive output U1a which is used to create a bias voltage level via the R2/R3 divider, That Allows the U1b oscillator to run. When the battery voltage drops below the set point of the output goes to zero and U1a U1b shuts off the oscillator, the voltage tripler Causing and MOSFET to shut down. Resistor R7 Gives the some hysteresis comparator circuit to Prevent comparator voltage oscillation near the shutoff. The circuit is analogous to a solid -state relay in latching that it shuts off its own power turns off When the MOSFET. This is achieved with diode D6 and the on-off switch. The circuit is switched on capacitor C11 acts like a momentary short -circuit, pulling the op -amp Vcc line up to the battery voltage. The whole circuit fires up long enough to turn the MOSFET on, after which operating current flows through the MOSFET and diode D6. http://energycoreproducts.com/us/
