Nissan has previewed its
electric vehicle EV platform on
a Tiida-based prototype to
demonstrate the superior driving
pleasure of a pure zero-emission
vehicle. It also showcased a
sophisticated EV-IT system
developed to support electric
driving 24/7 (24 hours a day, 7
days a week).
The dedicated EV platform is
comprised of a highly rigid
body, high-performance motor,
compact lithium-ion battery with
high power output and energy
capacity, delivering outstanding
driving performance and safety,
while offering a quiet and
peaceful driving experience – a
unique feature of a
fully-electric drivetrain.
The in-house developed electric
motor delivers 80kW/280Nm for
high response and powerful
acceleration. Nissan’s unique
motor control also contributes
to the vehicle’s seamless
acceleration.
The 24kWh laminated compact
lithium-ion battery pack is
placed under the vehicle floor
for more efficient packaging,
without compromising cabin or
cargo space. The battery layout
also allows smooth underfloor
air-flow which helps reduce
drag. Additionally, the
regenerative brake system
employed to recharge the battery
during deceleration and braking
extends the driving range to
more than 160km under a full
charge.
High durability is achieved by
employing an additional frame
for the battery pack to
significantly improve the
rigidity of the platform. The
combination of a high rigidity
platform and electric powertrain
minimises vibration and external
sounds to produce a quiet and
pleasing drive.
EV-IT support function
Nissan has developed a
sophisticated IT system for its
zero-emission EVs, connecting
the vehicle’s on-board
transmitting unit to a global
data centre to support EV
driving 24 hours 7 days a week.
Usability and convenience for EV
driving is achieved via the
following:
Maximum range display
-
With a simple touch of a
button, the navigation map
shows the driving radius
within range under the
current state of charge.
-
The system can calculate if
the vehicle is within range
of a pre-set destination.
Update on charging stations
-
The navigation system points
out the latest information
on available charging
stations within the current
driving range.
-
Detailed information for
each charging station will
also be displayed.
Timer function
-
The timer function enables
the air-conditioner or
battery charging to begin at
a specified time. The
air-conditioner can be
pre-set while the vehicle is
plugged-in to cool the cabin
to a desirable temperature
before driving begins,
without taxing the vehicle’s
battery. Meanwhile, the
battery charging can be set
to start at a specified time
at night to benefit from
more favourable electricity
rates.
EV
remote control and monitoring
function
-
The driver can monitor the
state-of-charge of the EV
via an online website and a
cellular phone. For
example, when the battery is
fully charged, a message
alert is sent to the
cellular phone. Additional
remote control functions
range from switching the
charging system ON/OFF or
setting the air-conditioner
timer.
To
be a leader in zero-emission
mobility, Nissan is progressing
its development for electric
vehicles and the key components.
The all-electric vehicle slated
for launch in 2010 will have a
unique design and body. Nissan
plans to unveil the design of
the production EV at its new
Global Headquarters Opening in
Yokohama on August 2nd. |
