How to use the EV DC Fast Charging Calculator (10–80%)
The Formula
Most EVs charge quickly from about 10% to 80% SOC, then power tapers to protect the pack. This calculator models full power to 80% (with ~8% loss) and reduced power above 80%.
Practical Example
Use your pack kWh and station peak kW from apps like PlugShare. Pair with EV Battery Range for total trip stops.
