CHICAGO About 2.2 million
charging stations for electric vehicles (EV) and plug-in hybrid
vehicles will be built and shipped worldwide each year by 2020,
a huge increase from an estimated 70,000 such stations shipped
globally in 2011, according to a new research paper.
The study by IMS
Researchacquired recently by IHS, which also owns
Lexington, Mass.-based consultancy IHS Global Insight
Inc.showed that 135,000 charging stations were installed
worldwide by the end of 2011 and forecast that 10.7 million
charging stations will be installed by the end of this decade.
The need for EV charging stations is growing along with
consumer adoption of alternative-fuel vehicles.
EV charging is location based.
Drivers need to charge where their vehicle is parked, with the
workplace set to be a key location. It suggests that businesses
and commercial property owners invest in charging facilities
for their employees use. If such investments dont
happen, it could negatively impact the EV market.
IMS Research estimated that the
United States will have the greatest number of deployed EV
charging stations in 2020, followed by China, Japan and
Many factors will encourage
drivers to shift from internal combustion engine vehicles to
EVs and plug-in hybrids, including stricter emissions
standards, energy security and energy price stability.
But charging timesit takes
about four hours today to fully charge a
24-kilowatt-hour-capacity battery using a 6.6-kw on-board
chargermust accelerate, according to the IMS study, and
the range of driving an EV can achieve on a single charge must
Above all, charging stations
have to be convenient, wired for technologies and cost
effective compared with gasoline fill-ups, the report said.
One alternative to fast-charging
is to replace a fully discharged battery with one that is fully
charged. This battery-switching approach is already being done
in Australia, China, Denmark, Israel, the Netherlands and the
United States, but there is limited support for
battery-switching technology among automakers.
