AVR based desulfator (schematic)

I certainly took my time putting this one together. This is a

desulfator based on Alastair Couper's original design. I made a few

changes.

 

1. AVR microcontroller instead of a 555 timer for PWM

2. Built in thermistors to prevent the board for overheating

3. TTL serial out for ZigBee transceiver

4. BCD LED display for battery voltage (0-79V)

 

What I hope to achieve with this circuit is a way to remotely monitor

battery arrays as they are desulfating. This could greatly reduce the

amount of labor required to recondition flooded lead acid batteries.
