Intelligent Charging System for EVsFord Motor Company has developed an intelligent charging system that
previews how its production vehicles will interact with the grid. The
unnamed system enables all-electric and plug-in hybrid vehicle owners
to restrict charging to when electricity prices fall below a certain
threshold, or even "when the grid is using only renewable energy such
as wind or solar power," according to Ford.
There's a natural
synergy for customers to put solar on their homes and buy hybrids/EVs,
who can then drive free of fossil fuel guilt.
In its ongoing testing of converted PHEV
Ford Escapes, the company is leveraging communications systems it
designed including SYNC, SmartGauge, and Ford Work Solutions. The
vehicles are communicating with the grid through smart meters over a
wireless network using the Zigbee protocol, but Ford hasn't committed
to a network platform for its production vehicles.
Open Source Design Comes to Green
I've been waiting for the advent of "open source" strategies in design to hit the green and climate change arena. It's coming... I wonder if Obama's approach to greening faster, stronger, better had anything to do with this strategy.
Ford said its final communications system will be designed to work
with a variety of smart meters.
The first generation of EVs is likely
to use a mix of proprietary and "open" standards that are still in
development. Each company will likely offer some part of their charge
management technology to others in hopes that it would become industry
standard.
The batteries in the 21 test vehicles are from Johnson
Controls-Saft, which will also be supplying the batteries for its
production PHEV.
Ford will spend $14 billion over 7 years to retool to
manufacture advanced vehicles.
Ford has lined up some impressive utilities to help with the tests,
including Southern California Edison, American Electric Power, Progress
Energy, and 10 others, which will each receive some of the test fleet.
The agreement is to continue testing for three years, which is
interesting because the company plans to have a commercial PHEV for
sale in 2012 -- you might think that testing of PHEV grid interaction
would be moot at that point. Ford received $30 million in DOE grant
money to pay for part of the testing.
Ford is rigorously testing PHEVs now, but the all-electric Ford
Focus (due out a year earlier) is not being tested in a similar broad
fashion. Is developing an EV easier than a plug-in hybrid (with its two
systems for locomotion)?
