The
Ford Edge with HySeries Drive concept features a flexible vehicle
architecture which allows it to accept a wide variety of powertrain options.
HySeries Drive technology allows the Edge to accept gasoline engines, diesel
engines or fuel cells which can be used in conjunction with an electric motor
and battery pack. This allows Ford to produce, for example, a gasoline-electric
hybrid version for North America and a diesel-electric hybrid version for
Europe. "This vehicle offers Ford the ultimate in flexibility in researching
advanced propulsion technology," said Ford Motor Company's Gerhard Schmidt.
In its current form, the Ford Edge with HySeries Drive uses a 350-bar hydrogen
fuel cell (4.5 kg of useable hydrogen) in addition to electric motors which are
fed by a 336-volt lithium-ion battery pack. The Ford Edge with HySeries Drive is
always powered by its battery pack, but the pack itself can be recharged in one
of two ways.
Since the Ford Edge with HySeries Drive is a plug-in hybrid, the batteries can
be fully topped off by plugging the vehicle into a standard home outlet using
the onboard 110/220 charger. Once the battery pack has been whittled down to 40%
capacity, its second source of recharging comes online. The hydrogen fuel cell
takes over and generates electricity to replenish the battery pack.
All of this technology working together gives the Ford Edge with HySeries Drive
the equivalent combined city/highway economy rating of 41MPG. The vehicle is
able to operate for the first 25 miles on battery power alone given a fully
topped off battery. After that point, the fuel cell kicks in to replenish the
batteries giving an additional 200 miles of range. According to Ford, the
equivalent economy rating could jump to 80MPG for drivers who travel less than
50 miles per day.
