TL;DR
100 kWh battery, 10-hour AC charge, 634 km range, 10-80% in 27 min (Supercharger V3) DC fast charging. Home charging covers 80–90% of all energy; fast charging covers the rest.
If you are bringing a Tesla Model S home, you have 100 kWh to keep topped up and a 10-hour AC charge cycle to schedule around. That sounds intimidating until you map it to real life: 634 km is more than most weekly mileage, and an overnight plug-in covers it. Below is the full charging playbook for the Tesla Model S.
Home charging the Tesla Model S
Setting up the Tesla Model S's home charge is a one-time job that shapes the next several years of ownership. The Tesla Model S accepts standard AC at home and completes a full empty-to-full cycle in roughly 10 hours. For the typical owner, that translates to plugging in around 30% remaining at night and waking up to a full battery. Per-km charging cost on a standard residential tariff comes out far below an equivalent petrol car, and on off-peak time-of-use plans the gap widens further. Set the daily ceiling to 80% — that single discipline keeps the 100 kWh battery healthier for longer.
Fast charging the Tesla Model S
Public fast-charging is where the Tesla Model S's wider segment positioning becomes real-world relevant. The Tesla Model S supports DC fast charging with a typical session profile of 10-80% in 27 min (Supercharger V3), which is what you'll use on road trips and the occasional bad-planning day. Plan long trips around natural stops — coffee, lunch, restroom — so the charge happens in parallel with something you'd do anyway. 634 km of range plus one DC stop is enough for almost any single-day journey within the country.
Tesla Model S battery longevity
Battery health on the Tesla Model S is largely about your daily routine, not big interventions. Avoid leaving the 100 kWh pack at very low or very high state of charge for long periods. Pre-condition before fast charging in cold weather — the battery accepts higher current when warm, which means a shorter session and less heat stress. Tesla's battery management system on the Tesla Model S is conservative by design, so most owners who follow basic charging hygiene see minimal degradation over the first three to four years.
Practical next steps
Set the Tesla Model S to schedule charging for off-peak tariff hours. Most utilities offer a night-rate window that cuts per-kWh cost meaningfully — the savings add up over a year.

Frequently asked questions
- Does the Tesla Model S support DC fast charging?
- Yes — the Tesla Model S supports DC fast charging with a typical session time of 10-80% in 27 min (Supercharger V3). That covers most road-trip needs in under a meal break.
- What's the per-km charging cost for the Tesla Model S?
- At home on off-peak tariff, the Tesla Model S costs a small fraction of an equivalent petrol car per km. Public fast charging is several times that — still cheaper than petrol on a typical session, but the gap narrows.
- What's the best daily charging routine for the Tesla Model S?
- Plug in when you get home, set the cap to 80%, schedule the charge for off-peak hours, and forget about it. That single habit covers most Tesla Model S owners' daily needs and is gentlest on the battery.
- How long does the Tesla Model S take to charge fully?
- On a standard 7 kW AC wall box, the Tesla Model S takes about 10 hours to go from empty to full — covering its full 100 kWh battery. Most owners plug in overnight at 30% remaining and wake up to a full charge.
The Tesla Model S's charging spec is among the more accommodating in its segment — make use of that by setting up a home box on day one and keeping fast-charge sessions short.
