EV Charging Reliability Index
How reliable is EV charging in the US?
31 reliability reports (availability readings and driver check-ins) in the last 30 days · last Oct 20, 2026. A network is ranked once 3 of its stations each have 10+ reports in 30 days.
All figures are the average 30-day reliability score as of October 20, 2026. A machine-readable feed of this index is available at /api/v1/reliability.

How We Measure Reliability
Each station's 30-day reliability score blends two signals: automated availability checks (weighted 1×) and driver-reported charging outcomes (weighted 2×, because a real successful or failed charge is a stronger signal than a status ping). A network, state, or city score is the average across its scored stations. A station receives a score only after 10 or more reports in the last 30 days; below that we show the raw dated count of driver reports instead, so brand-new or rarely-used locations don't skew the rankings.

Frequently Asked Questions
How is EV charging reliability measured?
Reliability blends automated availability checks (weighted 1×) and driver-reported charging outcomes (weighted 2×) over a trailing 30-day window, averaged across each network's, state's, or city's scored stations.
