Silverado EV RST
Premium electric truck. Here's what its onboard charger actually needs from your home's electrical panel.
Home (Level 2) charging facts
Pulled straight from the Silverado EV RST's onboard charger rating - not a generic EV number.
- Onboard charger draw
- 19.2 kW
- ~80A at 240V (kW × 1000 ÷ 240)
- Empty-to-full at max Level 2
- 10.4 hrs
- 200 kWh battery ÷ 19.2 kW
- Range added per hour
- ~36 mi/hr
- 19.2 kW × 1.9 mi/kWh efficiency
- DC fast charging
- 350 kW max
- Public chargers only - tapers as the battery fills
Typical full-speed install
80A charger on a 100A circuit
Reaches this car's 19.2 kW ceiling. Whether your panel has room for that circuit depends on everything else already on it - that's the actual assessment.
Connector
NACS
NACS (North American Charging Standard, originally Tesla's plug) is now the connector most new EVs are shipping with for both home Level 2 and public DC fast charging.
On the Silverado EV RST specifically, that connector carries up to 19.2 kW at home on Level 2 and up to 350 kW on public DC fast hardware.
Charging speed by circuit size
None of these common home circuit sizes reach this car's 19.2 kW onboard ceiling - it can use every amp up to 48A.
| Charger setting | This car actually draws | Range added / hour | 8-hr overnight |
|---|---|---|---|
| 16A | 3.8 kW | ~7 mi | ~56 mi |
| 24A | 5.8 kW | ~11 mi | ~88 mi |
| 32A | 7.7 kW | ~15 mi | ~120 mi |
| 40A | 9.6 kW | ~18 mi | ~144 mi |
| 48A | 11.5 kW | ~22 mi | ~176 mi |
Overnight, at full onboard speed
288 mi / 8 hrs
360 mi across a 10-hour window, at 19.2 kW.
Approximate cost to fill from empty
$26.00
Assumes $0.13/kWh (a national-average estimate, not your local rate) × 200 kWh - about $0.068/mile.
Chevrolet Silverado EV charging questions
How long does it take to charge a 2023–2026 Chevrolet Silverado EV RST on a Level 2 charger?
About 10.4 hours from empty to full at its 19.2 kW onboard-charger ceiling (200 kWh battery ÷ 19.2 kW).
Times scale with amperage - see the circuit-size table above for other settings.
What amperage does a Chevrolet Silverado EV draw on Level 2?
At its full 19.2 kW rate, the Chevrolet Silverado EV draws about 80A at 240V (kW × 1000 ÷ 240 = amps).
Can a Chevrolet Silverado EV use a 48-amp charger?
Yes, and it'll use the full 48A. A 48A charger delivers ~11.5 kW, which is at or under this car's 19.2 kW ceiling - about 22 mi of range per hour.
How much range does a Chevrolet Silverado EV add per hour on a Level 2 charger?
About 36 miles of range per hour at its 19.2 kW ceiling (19.2 kW × 1.9 mi/kWh efficiency).
How much range does an 8-hour overnight charge add to a Chevrolet Silverado EV?
Roughly 288 miles from an 8-hour overnight charge (36 mi/hr × 8 hours), or about 360 miles across a 10-hour window.
What's the DC fast charging ceiling for a Chevrolet Silverado EV?
Up to 350 kW on a public DC fast charger - well above its 19.2 kW Level 2 (home) ceiling, though DC fast rates taper as the battery fills.
