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. Stations need a minimum number of signals before they receive a score, so brand-new or rarely-used locations don't skew the rankings. See our full methodology and data sources.
