"A dead, irreplaceable battery is often the demise of an otherwise perfectly
good piece of equipment, and it can be incredibly frustrating. New research
shows, however, that the opposite may be true when it comes to the batteries
running electric vehicles.
The Globe and Mail
reports that a study done in March by Recurrent Motors
Inc. — a Seattle-based battery analysis company — showed that overall, EV
batteries are actually very reliable and long-lasting. In fact, they may last
longer than the vehicles themselves.
The study took real-world data from 15,000 EVs of various makes and models in
the U.S. By linking to the vehicles’ connectivity systems, the company took
several battery readings daily, including charging activity, EV battery level,
and estimated range.
The data showed that most EVs driven close to 100,000 miles still have at least
90 percent of their original range left.
“I was surprised how well batteries are holding up, and how relatively
infrequently batteries are being replaced,” Liz Najman, researcher and
marketing manager at Recurrent and the study’s author, told The Globe and
. “That was a shock.”
The publication did report, however, that Najman made sure to point out that
individual vehicles vary and that Recurrent’s data is constantly evolving. This
is mainly because most EVs aren’t that old, with nearly 30 percent currently on
the road in the U.S. being sold just last year. The majority of the rest are
less than six years old.
The cost of replacing an EV battery can range from $5,000 to $22,000, which few
people would be willing to pay, especially on a used car whose warranty is up.
Data from the study positively showed that, outside of official recalls, only
1.5 percent of cars had batteries replaced.
The company hopes this promising data will alleviate people’s concerns and
encourage them to comfortably switch to an EV, possibly even a used one."
I'm already on my second used EV. No battery issues so far.
