Smart fortwo Electric Charging Time
A 2019 Smart fortwo Electric takes about 3 hours to charge from empty to full on a 240-volt Level 2 charger, according to its EPA test. On a standard 120-volt outlet it takes about 13 hours. A full charge puts about 18 kWh through the plug for 58 miles of range.
Smart fortwo Electric charging time by charger
Figures for the 2019 EQ fortwo (coupe). 20% to 80% is a typical daily top-up; 0% to 100% is a full charge from empty.
| Charger | Power | 20% to 80% | 0% to 100% |
|---|---|---|---|
| Level 1, 120 V outlet (12 A) | 1.4 kW | 7 hr 30 min | 12 hr 30 min |
| Level 2, 240 V, 16 A | 3.8 kW | 2 hr 49 min | 4 hr 41 min |
| Level 2, 240 V, 24 A | 5.8 kW | 1 hr 52 min | 3 hr 8 min |
| Level 2, 240 V, 32 A | 7.7 kW | 1 hr 24 min* | 2 hr 21 min* |
| Level 2, 240 V, 40 A | 9.6 kW | 1 hr 8 min* | 1 hr 53 min* |
| Level 2, 240 V, 48 A | 11.5 kW | 56 min* | 1 hr 34 min* |
* Only if the car's onboard charger accepts that much power. On its EPA test it charged at about 6 kW; if that is its limit, a faster wall charger won't shorten the 3-hour full charge.

For home and public AC charging. DC fast chargers are much faster at first and then slow down past about 80%, so this formula does not fit them.
Cost to charge a Smart fortwo Electric
A full charge from empty draws about 18 kWh from the wall. At 18 cents per kWh it costs about $3.24, and a 20% to 80% top-up about $1.94. The EPA rates the EQ fortwo (coupe) at 31 kWh per 100 miles, which works out to 5.6 cents a mile. The US average home rate was 18.16 cents per kWh in August 2026 (EIA); the EV charging cost calculator takes your own rate.
Smart fortwo Electric 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 smart's quoted figure for the fortwo. The EV charging curve guide explains why it slows.
