So the electronics actually measures the amp hrs used and then calculates SOC% ?. Is there any way to read amp hrs instead of SOC%? Does the SOC calculation adjust for battery degradation due to age and number of charge cycles. I don't understand how it can show SOC = 0% and I can still go?
I use Cycle Analist as you can see from schematics of my conversion.
It calculates Ah used .
Back to Eplus drive -
yes hub electronics /you can call it BMS but it is not right/ chip PIC register charge going into NMH hub and register discharge also. I guess SOC is displayed based on discharge count compared with fullcharged count .
Cycle Analist is wonderful device which display many parameters - Whs, Ahs, kilometers, voltage, amps, charge cycles, etc. It does it using voltage of batt, current measured by shunt , wheel magnet,
Of course it costs for the reason - designed and bulit in Canada , no crappy China "technology"
I bought all those bargain China brand "meters" , was only waste of money. Celllog is rather reliable however if you buy spare ones to replace irratic ones.
