env.ev-charging-cost Calculator
Calculates the electricity cost of a full EV charge and the cost per kilometre at home vs. public charging rates, accounting for charger efficiency losses. Home charging at off-peak rates is typically 4–6× cheaper per kilometre than fast public charging.
Inputs
Battery Kwh
Maximum throughput or storage. Operating near 100% capacity typically increases failures and wait times.
Efficiency Mi Kwh
Useful output divided by total input, as a percentage. 100% is impossible due to losses (heat, friction, resistance).
Home Rate
Amount per unit of time or per unit quantity. Check the denominator before interpreting.
Dc Fast Rate
Amount per unit of time or per unit quantity. Check the denominator before interpreting.
Results
vehicle range (mi)
The difference between the maximum and minimum values.
home charge cost (full)
The total monetary cost computed for the given inputs.
DC fast charge cost (full)
The total monetary cost computed for the given inputs.
home cost per mile
The total monetary cost computed for the given inputs.
DC fast per mile
