Measure an EV's energy use and the cost to charge it.
Battery size divided by EPA-style range yields energy per mile, then converted to the metric figure and charged cost. Energy efficiency converts directly into charging cost, so it is the metric that proves whether an EV is cheap to run.
EV Range Efficiency
kWh/mi = battery / range; cost per mile = kWh/mi x price
kWh/mi = battery / range; cost per mile = kWh/mi x price Battery size divided by EPA-style range yields energy per mile, then converted to the metric figure and charged cost.

This calculator takes 3 inputs: Battery capacity, Range, Electricity. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
