Charging slows near 100% on most EVs to protect battery health — this estimate assumes a roughly constant rate, which is most accurate for the 20-80% range.

How EV charging time is calculated

Time (hrs) = Energy needed (kWh) ÷ Charger power (kW)
Energy needed = Battery kWh × (Target % − Start %)

A typical Level 1 (120V) home outlet delivers around 1.4kW, while a Level 2 (240V) home charger delivers 3.7-11.5kW depending on the circuit — the difference between an overnight top-up and an all-day trickle charge. Check the running cost of that charge with the EV home charging cost calculator.

Charging time is really the smaller of two numbers you need — the other being cost, covered in our dedicated EV charging cost calculator. Together they answer the two questions that actually matter for planning a charging routine: how long will my car take, and what will it cost me to do it regularly.

Frequently asked questions

What's the difference between Level 1 and Level 2 charging?

Level 1 uses a standard 120V household outlet and is slow (often 30+ hours for a full charge), while Level 2 uses a 240V circuit like a dryer outlet and can fully charge most EVs overnight.

Why does charging slow down near 100%?

Lithium-ion batteries taper their charge rate near full to protect cell longevity — the last 10-20% often takes disproportionately longer than the middle of the charge curve.

Does charging time include the taper near a full charge?

This estimate assumes a roughly constant charging rate, which holds well for the 20-80% range most EV owners actually use daily — the last 10-20% of a full charge typically tapers and takes longer than this simple estimate suggests.
