Battery Balancer circuit board design

The device will use an inductor connected to an oscillator to transfer energy between two adjacent batteries in series during charging and discharging to keep them at an even state of charge [see Picture [url removed, login to view]]. Furthermore voltages of each battery must be monitored once every 10ms using a delta-sigma ADC for use in a noisy environment. Should battery voltage go above or below a preset limit, a fault pin must activate that triggers a relay which will stay triggered until voltage levels return to normal parameters. Device must go into a low power sleep mode if variance in battery voltages is within preset parameters. If any unit freezes or otherwise fails a relay must be triggered which shuts off charging or discharging.

Tri-Color LED used to display system state:

Green- Balancing

Blue- Balanced

Red blink- Low Voltage Fault

Red - High Voltage Fault

Battery voltages range from 1V to 20V

Number of batteries in series can range from 3 to 120

The current transfer requirements are up to 10A

Programmable with RS-232 pins

Circuit testing and improvements are welcome but not required. PCB layout of device should be in Gerber RS-274X and NC Drill files.
