EV charging time calculator
Find out how many hours it takes to charge your electric car at home. Enter your battery size, the charge level you want to reach, and your charger type to get an instant estimate for Level 1 and Level 2.
How it works
- Takes your usable battery size and the percentage you want to add.
- Divides the energy needed by your charger's real-world power output.
- Accounts for charging losses so the estimate reflects wall-to-battery reality.
What changes your result
- Charger power — Level 1 (~1.4 kW) versus Level 2 (7–11 kW) is the single biggest factor
- Battery size and how much charge you add (20→80% vs 0→100%)
- Charging losses — roughly 10% is lost as heat between the wall and the battery
- The car's on-board charger limit, which can cap AC charging below your charger's rating
Frequently asked questions
How long does it take to charge an EV at home?
On a Level 2 home charger (7–11 kW), most EVs add 20–80% in 3–6 hours. Level 1 from a standard outlet (~1.4 kW) is far slower and can take 20–40 hours, so it suits plug-in hybrids or light daily top-ups.
Is Level 2 charging worth it?
For most daily drivers, yes. Level 2 charges 5–7 times faster than a standard outlet, recharging overnight. It needs a 240-volt circuit and usually a dedicated breaker — use the panel-fit check to confirm your panel can support it.
Does charging slow down near 100%?
AC home charging is fairly linear, though the last 10–20% can taper slightly. Public DC fast charging slows much more above 80%, which is why many drivers stop there. This tool estimates typical AC home charging.
