Taycan 4S
All-wheel drive electric performance. Here's what its onboard charger actually needs from your home's electrical panel.
Home (Level 2) charging facts
Pulled straight from the Taycan 4S's onboard charger rating - not a generic EV number.
- Onboard charger draw
- 9.6 kW
- ~40A at 240V (kW × 1000 ÷ 240)
- Empty-to-full at max Level 2
- 9.7 hrs
- 93.4 kWh battery ÷ 9.6 kW
- Range added per hour
- ~27 mi/hr
- 9.6 kW × 2.8 mi/kWh efficiency
- DC fast charging
- 270 kW max
- Public chargers only - tapers as the battery fills
Typical full-speed install
40A charger on a 50A circuit
Reaches this car's 9.6 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 Taycan 4S specifically, that connector carries up to 9.6 kW at home on Level 2 and up to 270 kW on public DC fast hardware.
Charging speed by circuit size
The Porsche Taycan's onboard charger can't use more than 9.6 kW AC no matter how big the circuit - past 48A, 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 | ~11 mi | ~88 mi |
| 24A | 5.8 kW | ~16 mi | ~128 mi |
| 32A | 7.7 kW | ~22 mi | ~176 mi |
| 40A | 9.6 kW | ~27 mi | ~216 mi |
| 48A | 9.6 kWcapped by car | ~27 mi | ~216 mi |
Overnight, at full onboard speed
216 mi / 8 hrs
270 mi across a 10-hour window, at 9.6 kW.
Approximate cost to fill from empty
$12.14
Assumes $0.13/kWh (a national-average estimate, not your local rate) × 93.4 kWh - about $0.046/mile.
Porsche Taycan charging questions
How long does it take to charge a 2023–2026 Porsche Taycan 4S on a Level 2 charger?
About 9.7 hours from empty to full at its 9.6 kW onboard-charger ceiling (93.4 kWh battery ÷ 9.6 kW).
Times scale with amperage - see the circuit-size table above for other settings.
What amperage does a Porsche Taycan draw on Level 2?
At its full 9.6 kW rate, the Porsche Taycan draws about 40A at 240V (kW × 1000 ÷ 240 = amps).
Can a Porsche Taycan use a 48-amp charger?
Not to any real benefit. The Porsche Taycan's onboard charger tops out at 9.6 kW (~40A) - a 48A charger doesn't charge it any faster than one already sized to 40A.
How much range does a Porsche Taycan add per hour on a Level 2 charger?
About 27 miles of range per hour at its 9.6 kW ceiling (9.6 kW × 2.8 mi/kWh efficiency).
How much range does an 8-hour overnight charge add to a Porsche Taycan?
Roughly 216 miles from an 8-hour overnight charge (27 mi/hr × 8 hours), or about 270 miles across a 10-hour window.
What's the DC fast charging ceiling for a Porsche Taycan?
Up to 270 kW on a public DC fast charger - well above its 9.6 kW Level 2 (home) ceiling, though DC fast rates taper as the battery fills.
