EV charging reliability & performance. Independently measured.
Reported uptime does not tell you whether charging succeeds. We measure Availability and Charging Success Rate from public status data. Look up any station or operator and see what the feed recorded.

Symbioen is independent intelligence for EV charging — providing the transparent, unified metrics that stakeholders can actually trust.

Our system processes millions of raw events from chargers — cleaning and verifying the data, turning it into insights and tools for SLA and performance accountability.
The percentage of time stations were functional and available for charging.
A comprehensive Symbioen score (0-100) evaluating charger stability, error rates, availability and successful charging sessions.
The proportion of time chargers are actively delivering power to vehicles. Previously called Utilisation Rate; it measures occupancy, not energy delivered.
Share of status-derived charging sessions that stayed in a charging state for at least two minutes. Inferred from the public feed, not from billing records.
Symbioen Index
One published method for every network
Operators define uptime in different ways, so their numbers cannot be compared across the market. The Symbioen Index applies one published method to every network, so an operator and its buyer read the same evidence.
Reported uptime
95–99%
Typical operator figures, each under its own definition
vs.
Charging Success Rate, Q3 2026
82–91%
Status-derived, by country: Norway 81.7%, Sweden 84.7%, Finland 91.2%
Uptime and Charging Success Rate use different denominators, so the gap is not a count of failed sessions. It is a signal of where reported health and driver outcomes part ways. The Symbioen Index scores every network on both, so stations that look healthy on paper but fail in practice stop hiding inside a portfolio average.
How to work with us

Available now
Market Intelligence & Benchmarking
Public reports and the pages for each station, operator and municipality are free. A licence adds the interactive map with filters and period comparison for the countries you need.

Pilot
Station and connector alerts
A short list of the connectors that need attention: silent, failing sessions, or not recovering after a fault. Built for operators with 100 or more charging points in Sweden, Norway or Finland.

Operator Performance Verification
Verify the charging performance a network delivers, using operator session data and our published method. We are testing it with operators; a Verified status is published only after a completed verification.

Custom Reports
A report for one decision: an acquisition, an SLA dispute, a tender or a portfolio review. Built from the same data and method as the public rating, with the limits of the evidence stated.
