Really I am just asking for ideas as to the best way to read 60 different voltage inputs ranging from 3v - 4.2v in the smallest form factor and lowest parts count?
This is for my ebike. I have 10 battery packs and each one has 6 cells. Right now when traveling I am just reading the overall voltage of the batteries. This is not an optimal system of measurement. If one cell goes too low or too high there is the potential for thermal runaway with the lipo batteries I am using. This has never happened and the cells have always been very well balanced but I would like this information for piece of mind.
When I arrive home I can easily check each cell with the battery charger but this takes time and I have to remove and insert the charger 10 times to read and balance all 60 cells.
Solution so far
so far all I can figure is 10 atmega8 chips using every adc port and i2c protocol to relay that information back to an lcd. Anyone have one with fewer parts. All ideas are most welcome!
