What Makes EV Charging Stations Fail?

A new study sheds some light on a main concern for EV drivers: What's
causing problems with dead public EV charging stations?

Based on network data monitored across the United States this year,
the most common reasons for failed EV charging sessions are problems
with:

    station connectivity: 55 percent
    internal station faults or errors: 38 percent
    charging connector or cable: 4 percent
    credit-card reader: 1 percent
    display screen: 1 percent

CONNECTIVITY: The data suggests that more than half all charging
failures come from a station not being able to connect to its network
for authentication.

STATION INTERNALS: The next failure category, "internal faults or
errors," covers software and perhaps some hardware failures. Many EV
drivers have posted photos of non-working charging stations that have
seemingly frozen in the middle of rebooting, including what looks
suspiciously like Windows code on their screens. This is likely a host
of different issues, each of which has to be addressed separately, for
different stations from different makers. It's complicated.
