- All-electric and original hybrid electric prototypes unveiled -
TOKYO, Aug. 6 /CNW/ - Nissan Motor Co., Ltd. today unveiled all-electric
and original hybrid electric prototype vehicles, both powered by advanced
lithium-ion batteries. Under the NISSAN GT 2012 business plan, the company has
committed to zero-emission vehicle leadership, and has announced plans to
introduce an all-electric vehicle in 2010 and mass market globally in 2012.
Electric Vehicle (EV)
Powered by advanced lithium-ion batteries, the EV prototype is part of
Nissan's substantial research and development program on zero emission
vehicles. This latest generation vehicle features a front-wheel drive layout
and uses a newly developed 80kW motor and inverter. The advanced laminated
compact lithium-ion batteries are installed under the floor, without
sacrificing either cabin or cargo space.
The production vehicle to be introduced in 2010 will have a unique
bodystyle and is not based on any existing Nissan model.
Hybrid Electric Vehicle (HEV)
The Nissan original HEV delivers two breakthrough technologies - a
high-performance rear-wheel drive hybrid system and parallel-powertrain hybrid
system. The hybrid employs Nissan's own originally developed hybrid technology
and its first rear-wheel drive hybrid powertrain.
The parallel-powertrain system comprises an energy-optimizing system with
two clutches, where one motor is directly connected to an engine and
transmission via two separate clutches. Under changing driving conditions, the
motor switches between the two clutches to optimize and conserve energy
utilization as well as improve fuel-efficiency.
The parallel-powertrain hybrid system eliminates the need for
conventional torque converters, contributing to higher responsiveness and
linear acceleration for improved driving feel.
The dynamic characteristics of the clutches are as follows:
- Idle-stop: The battery is used to power the motor to save on fuel.
- Regular driving: The engine is used to power the motor as well as
regenerate the battery.
- Acceleration: Both the engine and battery (power assist) is used to
power the motor to achieve smooth acceleration.
- Deceleration: Energy from braking is conserved and re-routed back to
regenerate the battery.
The advanced lithium-ion batteries used in both prototypes are sourced
from the Nissan-NEC joint-venture, AESC (Automotive Energy Supply
Corporation). These advanced batteries offer superior performance,
reliability, safety, versatility and cost competitiveness, compared to the
conventional nickel metal-hydride batteries. Its compact laminated
configuration delivers twice the electric power compared to conventional
nickel-metal hydride batteries with a cylindrical configuration. The compact
batteries also allow for improved vehicle packaging and a wide range of
Nissan has long experience in electric-powered vehicle development,
commencing from the first EV "Tama Electric Vehicle" back in 1947. The company
introduced the world's first application of lithium-ion batteries to the
Prarie Joy EV in 1996, followed by the ultra-compact electric vehicle,
Hypermini, released in 2000. Nissan also introduced its first original hybrid
vehicle Tino Hybrid back in 1999 in Japan. In 2006, the Altima Hybrid was
introduced in North America using licensed technology.
Under the Nissan Green Program 2010 environmental plan, the company aims
to develop new technologies, products and services that can lead to real-world
reductions in vehicle CO(2) emissions, cleaner emissions, and recycling of
resources. Nissan continues to invest substantially in a wide range of
technologies including CVT (Continuously Variable Transmission), VVEL
(Variable Valve Event and Lift), clean diesels, biofuels and fuel cell
