Voltage monitoring of Individual Batteries in a Bank
Archiver
Posts: 46,084
I want to monitor/log the voltages of the 6 individual 6-volt
batteries in a 36 volt bank using the Stamp. The voltages
would range from approximately 5.5 [noparse][[/noparse]discharged] to 7.5
[noparse][[/noparse]full and charging]. I have thought of using 6 DPST relays
to input the battery voltages sequentially into an a/d
converter but now think that there might be a more elegant
and safer solution; perhaps using linear optoisolators.
Although not necessary it would be nice to use the battery
bank to supply the power for the circuitry and the Stamp.
Any help and advise for this application would be
appreciated but as I am not an electronics engineer I need
part descriptions and detailed description of the
recommended circuit. I know that I need a voltage divider
to drop the battery reading to less than 5 volts. As this
would be a ‘one off’ application part cost, within reason, is
not paramount [noparse][[/noparse]but ready availability is].
