Charger-to-EV ratio in Connecticut

How well the charging build-out is keeping pace with EV adoption. Lower numbers = more chargers per EV (better).

EVs per port
12.7
EVs per L2 port
16.7
EVs per DCFC port
53.2
BEVs per DCFC port
33.8

Numbers reflect publicly-accessible charging only (private/workplace/fleet sites excluded). Port counts are individual L2 or DCFC ports — a site with 8 DCFC ports contributes 8, not 1. EV count is BEV+PHEV combined; BEV-only is shown separately. Registration data is the latest annual AFDC/Experian snapshot. Compare all states →

How Connecticut compares

A mid-tier EV market — adoption is real but still has room to grow.
