The maximum current is determined by the ebikeâs controller, and is usually somewhere between 15-30 amps. An ebike with a 48V battery and a 20 amp peak controller would theoretically be capable of a nominal 960 watts of instantaneous power. This is where things get complicated though, because ebike manufacturers donât always rate their parts this way.
The voltage on a discharging capacitor, with time constant T, and initial voltage Vo, varies with time exponentially as; V(t) = Voe^-t/T. So the voltage after one time constant is; V(T) = Vo/e (about 46% of Vo) The Charging eq is; V(t) = Vo[1 - e^-t/T] The voltage after one time constant is; V(T) = Vo[1-1/e] (about 54% of Vo) Since e=2.718 it is common practice to approximate this as ~ 3. Then the discharge voltage afer one time constant is approximately (1/3)Vo And the charging voltage after one time constant is approximately (2/3)Vo
