How much does it cost to charge a Mercedes-Benz CLA (electric)?

At the U.S. average residential rate (16.9¢/kWh), a full home charge of the Mercedes-Benz CLA (electric) (85 kWh, ~350 mi range) costs about $15.96 — 4.4¢ per mile. Public DC fast charging at ~43¢/kWh runs about $36.55 per full charge.

How long does it take to charge a Mercedes-Benz CLA (electric)?

On a Level 2 home charger the Mercedes-Benz CLA (electric) accepts up to 11 kW, so an empty-to-full charge takes about 8.6 hours (roughly 43 miles of range per hour). At a DC fast charger its ~320 kW peak gives a 10–80% charge in about 17 minutes. On a standard 120V outlet (Level 1), a full charge takes around 71 hours.

What home charger do I need for a Mercedes-Benz CLA (electric)?

Any Level 2 (240V) charger works; the Mercedes-Benz CLA (electric)'s onboard charger caps AC charging at 11 kW, so a 48A unit on a 60A circuit reaches that limit — a more powerful charger will not charge it faster. The electricity cost is the same at any speed: $15.96 per full charge at the national-average rate.

Mercedes-Benz CLA (electric) charging speed & home charger

Cost does not depend on speed — a kWh is a kWh — but time does. These estimates use the Mercedes-Benz CLA (electric)'s onboard AC limit (11 kW) and its typical DC fast-charging peak (~320 kW); real sessions taper as the battery fills.

~71 h

Level 1 (120V outlet), empty → full

Home charger sizing: the Mercedes-Benz CLA (electric) tops out at 11 kW on AC, so a 48-amp charger on a 60-amp circuit reaches its limit — a bigger unit adds nothing. Overnight (8 hours) on Level 2 restores about 341 miles, more than most daily driving. See Level 1 vs Level 2 and how many kWh it takes to charge an EV.
