Bolt EV LT
Discontinued but widely owned. 7.7kW onboard charger maxes at 32A — a 40A charger is plenty. Here's what its onboard charger actually needs from your home's electrical panel.
Home (Level 2) charging facts
Pulled straight from the Bolt EV LT's onboard charger rating - not a generic EV number.
- Onboard charger draw
- 7.2 kW
- ~30A at 240V (kW × 1000 ÷ 240)
- Empty-to-full at max Level 2
- 9.2 hrs
- 66 kWh battery ÷ 7.2 kW
- Range added per hour
- ~28 mi/hr
- 7.2 kW × 3.94 mi/kWh efficiency
- DC fast charging
- 55 kW max
- Public chargers only - tapers as the battery fills
Typical full-speed install
32A charger on a 40A circuit
Reaches this car's 7.2 kW ceiling. Whether your panel has room for that circuit depends on everything else already on it - that's the actual assessment.
Connector
CCS
CCS (Combined Charging System) is the most common connector on non-Tesla EVs for both home Level 2 charging and public DC fast charging.
On the Bolt EV LT specifically, that connector carries up to 7.2 kW at home on Level 2 and up to 55 kW on public DC fast hardware.
Charging speed by circuit size
The Chevrolet Bolt EV's onboard charger can't use more than 7.2 kW AC no matter how big the circuit - past 32A, a bigger charger buys you nothing on this car.
| Charger setting | This car actually draws | Range added / hour | 8-hr overnight |
|---|---|---|---|
| 16A | 3.8 kW | ~15 mi | ~120 mi |
| 24A | 5.8 kW | ~23 mi | ~184 mi |
| 32A | 7.2 kWcapped by car | ~28 mi | ~224 mi |
| 40A | 7.2 kWcapped by car | ~28 mi | ~224 mi |
| 48A | 7.2 kWcapped by car | ~28 mi | ~224 mi |
Overnight, at full onboard speed
224 mi / 8 hrs
280 mi across a 10-hour window, at 7.2 kW.
Approximate cost to fill from empty
$8.58
Assumes $0.13/kWh (a national-average estimate, not your local rate) × 66 kWh - about $0.033/mile.
Chevrolet Bolt EV charging questions
How long does it take to charge a 2020–2023 Chevrolet Bolt EV LT on a Level 2 charger?
About 9.2 hours from empty to full at its 7.2 kW onboard-charger ceiling (66 kWh battery ÷ 7.2 kW).
Times scale with amperage - see the circuit-size table above for other settings.
What amperage does a Chevrolet Bolt EV draw on Level 2?
At its full 7.2 kW rate, the Chevrolet Bolt EV draws about 30A at 240V (kW × 1000 ÷ 240 = amps).
Can a Chevrolet Bolt EV use a 48-amp charger?
Not to any real benefit. The Chevrolet Bolt EV's onboard charger tops out at 7.2 kW (~30A) - a 48A charger doesn't charge it any faster than one already sized to 30A.
How much range does a Chevrolet Bolt EV add per hour on a Level 2 charger?
About 28 miles of range per hour at its 7.2 kW ceiling (7.2 kW × 3.94 mi/kWh efficiency).
How much range does an 8-hour overnight charge add to a Chevrolet Bolt EV?
Roughly 224 miles from an 8-hour overnight charge (28 mi/hr × 8 hours), or about 280 miles across a 10-hour window.
What's the DC fast charging ceiling for a Chevrolet Bolt EV?
Up to 55 kW on a public DC fast charger - well above its 7.2 kW Level 2 (home) ceiling, though DC fast rates taper as the battery fills.
