How reliable are public EV chargers in Norway?

In Q2 2026, Norwegian public chargers were in a working status 94.78% of the time we observed them. Of the charging sessions we inferred from status changes, 86.7% were successful. Both figures are slightly lower than in Sweden, but each Norwegian charging point handled about twice as many sessions.

What the two main figures measure

Availability is the share of observed time a charging point reported a working status. Successful charging sessions are the share of inferred sessions where charging lasted at least two minutes. They have different denominators, so do not subtract one from the other.

The success bar is low. A session that stopped after five minutes still counts, so the figure shows that charging started, not that the driver got the charge they wanted.

Busier chargers than in Sweden

Norway had fewer than half as many public stations as Sweden (4,313 against 9,693) but produced more inferred sessions: 4.2 million against 3.7 million. That is about 139 sessions per charging point in Norway and 66 in Sweden. Norway also has more fast charging: 44.8% of its stations offer more than 22 kW, against 28.4% in Sweden.

Use grew during the quarter. The share of time chargers were in use rose from 9.25% in the first full week to 11.10% in the last. Over the same weeks availability slipped from 95.57% to 94.62%. The weekly share of successful sessions moved between 84.7% and 87.7% with no clear trend.

Recording gaps affected five weeks between 11 May and 21 June. Weekly values for those weeks are estimates, and the session totals for both countries are lower than the true numbers.

How much of the network we could measure

Of the 4,313 stations listed at the end of the quarter, 3,850 sent at least one status update and 3,503 had enough history to be scored in the last full week. That is 81% of the network, against 72% in Sweden. The other 463 stations sent no status data at all during Q2.

A station without a score is not a broken station. We could not see it well enough to judge. For the same reason, Bremanger, Hjelmeland and Sokndal appear as not scored in the full report: none of their stations had enough data.

What the public data cannot show

Public status data does not show how much energy was delivered, whether payment worked or what each driver experienced. We can check charging outcomes and energy delivered per session from the operator’s session records through Operator Performance Verification. Fleet and vehicle data shared with consent can add what drivers experienced.
