Charging & charge time

AC versus DC, where the stated charge times come from and what counts in practice.

What is the difference between AC and DC charging?
AC charging runs via alternating current and the car’s onboard charger; at home or at public points, typically up to 11 or 22 kW. DC charging delivers direct current straight to the battery via a fast charger and reaches much higher power. The onboard charger limits the AC rate; the charging curve and battery temperature limit the DC rate.
Why is fast charging not equally fast the whole time?
A fast charger reaches the stated peak power only in part of the charging curve. Above about 80 percent state of charge the power drops sharply to spare the battery. That is why 10-80 percent is used as the reference window, not 0-100 percent. Cold and a cold battery slow charging further.
Where do the charge times on the model pages come from?
They are manufacturer figures from OEM datasheets, usually the 10-80 percent DC window and the maximum AC power. They are not times measured by us. Real-world results depend on the charger, the battery temperature and the state of charge on arrival.
What does the stated maximum charging power mean?
The maximum charging power (kW) is a peak the car reaches briefly under favourable conditions, not an average over the whole charging session. For a realistic estimate the average over 10-80 percent weighs more. See the term explanation at charging power.
Does autoseeker help me choose a charge card or charger?
No. We are a specs database with tools and reviews, not a provider and not a comparison site for charge cards, chargers or energy contracts. We show factual charging specs and do not refer on to commercial charging offers.
How much slower does an EV charge in winter?
A cold battery charges slower because the charging power is limited until the cells are up to temperature; some cars precondition the battery on the way to a fast charger. The effect differs strongly by model and temperature, so we do not give a fixed percentage. The charging picture is shown per model with a manufacturer-figure label.
