An electric car on the 7-day Ring Road: which days fit a 350 km range

An electric car with a real summer range of 350 km drives six of the 7-day Ring Road ledger's seven days on an overnight charge and needs one stop at a fast charger, on Day 6 between Akureyri and Borgarnes. At 400 km the answer is the same, because Day 6 is 325 km and a 20 per cent reserve makes 320 km the usable figure. In winter, taking the Norwegian Automobile Federation's finding that cold can cut range by up to 35 per cent, five of the seven days need a stop. The public charging maps that would place every post could not be read as text on 1 November 2026 (ON's lives at app.on.is, Ísorka's behind a button to an external map, both script-only), so this post names only the chargers the operators have named in dated notices.

#The ledger re-run

Usable range is the real range less a 20 per cent reserve, which is what any sensible driver keeps on a road with no charger in sight. Summer: 280 km usable at 350, 320 at 400. Winter: the NAF page on range standards, updated 2 October 2026, says winter range "kan være mellom fire og 35 prosent kortere enn oppgitt WLTP-rekkevidde"; at the bad end, 350 becomes 228 real and 182 usable, 400 becomes 260 and 208.

The table assumes the car leaves each sleep town full; ask at booking whether the guesthouse has a charger and what it delivers, because without an overnight charge the table is wrong in every row.

#Where the stops are known

ON Power's rapid-charging page, read 1 November 2026, says it operates 53 fast-charging stations "located at the main stops along the Ring Road" and names none. Its news item of 20 August 2021 on the Baulan station names the chain between Reykjavík and Akureyri — Reykjavík, Baulan, Víðigerði in Húnaþing, Varmahlíð and Akureyri — at 150 kW, and says that with Baulan added "eru ekki nema 100 kílómetrar á milli hraðhleðslustöðva". That solves Day 6: Varmahlíð is 95 km from Akureyri and Víðigerði about 195, so the stop that gets a 350 km car to Borgarnes is Víðigerði, with 130 km to go. Ísorka's news of 21 February 2023 names 150 kW posts at Ánanaust in Reykjavík, Hella and Kirkjubæjarklaustur, built with Olís; those cover Day 1 and Day 2's winter stops. Ísorka's network page, read the same day, gives "4.300" connection points and a map behind a button. For Days 3 and 4 in winter, the fjords and the Jökuldalsheiði moor, this site has no dated operator notice naming a post and says so; the maps in the apps are the only source.

#Time and money

Charging time is an estimate with its assumptions stated. At 18 kWh per 100 km, the figure this post uses for a mid-size car (change it for yours), 100 km is 18 kWh, which a 150 kW post delivers in about ten minutes if the car accepts the full rate and twenty or more in cold or above 80 per cent. Day 6's summer stop is a coffee at Víðigerði; the five winter stops are five coffees.

Cost: the loop is 1,555 km, so 280 kWh at 18 kWh/100 km. ON's tariff page, in force from 1 January 2026 and read 1 November 2026, lists DC fast charging at 69 ISK/kWh including VAT (the table on the page is garbled and shows a second figure beside it; 69 is the one the row labels support). If every kilowatt-hour came from a fast charger the loop would cost 19,320 ISK, against 33,100 for petrol at the 1 November pump price on this site's fuel post. Overnight AC charging at a guesthouse is cheaper where it is offered and priced; where it is free, the loop's energy cost is the handful of fast charges.

The table is only as good as the overnight charge and the winter figure, and the winter figure is a Norwegian test at −15 to −32 °C (NAF's El Prix, 28 January 2026), colder than an Icelandic coast in January and about right for Jökuldalsheiði. Plan on the bad end. When the charging maps can be read as pages rather than apps, this post will list the posts by kilometre.
