The US average home rate was 18.16 cents per kWh in August 2026 (EIA); the EV charging cost calculator takes your own rate.
Mercedes-Benz CLA-Class fast charging
DC fast charging bypasses the car's onboard charger and is far quicker, but the speed depends on each model's charging curve, which slows as the battery fills. That's why fast-charge times are quoted from 10% to 80%. The EPA doesn't test DC charging, so check Mercedes-Benz's quoted figure for the CLA-Class. The EV charging curve guide explains why it slows.
