For continuously varying charge the current is defined by a derivative. Charge density = 2 C/m 3 It must be noted that charging current is due to the capacitive effect between the conductors of the line The product of the two yields the current going through the capacitor. 2) On average, this credit is equivalent to up to 30 complimentary fast charging sessions for the customer, based on an average fast charging session length of 30 minutes on EVgo chargers only and excluding taxes. DoD is one of the biggest contributors to degradation. In general, the cost of charging a Tesla is 3.6 times cheaper per mile than the cost of fueling a gas-powered car (4.56 cents per mile compared to approximately 16.66 cents per mile for gas vehicles). Resistance and capacitance as well as charging current must be given. = 5A. V = E IR (discharging), V = E + IR (charging) 17.
