Calculates the best charge amperage for your Tesla Model S or Model X battery.

EV ChAmp calculates the lowest charge amperage setting needed to replenish your electric vehicle's battery by a given time. The calculations are optimized for the Tesla Model S and Tesla Model X.

A typical scenario is at home where you would charge your electric vehicle (EV) overnight when electricity costs may be lower and such that by the time you need to leave for work, your battery has a full charge.

The main benefits of using the lowest possible amperage are prolonged battery life and lower electricity usage.
