The advanced lithium-ion batteries
used in the prototype vehicles feature
a compact, laminated configuration that delivers twice the electrical power
when compared to traditional cylindrical configurations. Nissan says that the
compact design of the batteries allows for improved vehicle packaging and a
wider range of applications when compared to traditional batteries.
The full electric vehicle uses the
advanced batteries along with a newly developed 80kW motor and inverter. Nissan
says the electric vehicle uses a front-wheel drive configuration and that the
advanced laminated batteries are installed under the floor of the vehicle. The
laminated design of the batteries means that the vehicles interior and storage
space are not sacrificed to battery storage. Nissan says that the full electric
vehicle will go into production in 2010 and will feature a new and unique body
style not based on existing Nissan vehicles.
Nissan's prototype hybrid electric
vehicle introduces a pair of new technologies Nissan says are breakthroughs --
a high-performance rear-wheel drive system and a parallel-powertrain hybrid
system. Nissan says that both the hybrid technology and the rear-wheel drive
are original designs -- in this case, the system is placed within a 2010
Infiniti G37 Sedan.
Nissan's parallel-powertrain system
connects one motor directly to an engine and transmission via two clutches.
This layout allows the vehicle to switch between the dual clutches to optimize
and conserve energy utilization and improve fuel-efficiency. Nissan says its
parallel-powertrain eliminates the need for typical torque converters and
contributes to higher responsiveness and linear acceleration.
Nissan describes the action of the
hybrid system as:
Nissan isn’t alone in introducing
new hybrid vehicles. Yesterday DailyTech reported that Honda was bringing the Insight back
to the U.S. as a 2010 model for an MSRP of $18,500. The Insight is rumored to
get over 70 miles per gallon.
