Nissan unveils new prototypes

Nissan today unveiled its new all-electric and original hybrid electric prototypes, both powered by lithium-ion batteries, with plans to introduce an all-electric vehicle globally in 2012.

The all-electric vehicle will be powered by advanced lithium-ion batteries, featuring a front-wheel drive layout and a newly developed 80 kilowatt motor and inverter. The batteries will be installed under the floor, so as not to affect cabin or cargo space.

The production vehicle will be introduced in 2010, featuring a 'unique' bodystyle, which isn't based on any current Nissan vehicle.

The hybrid prototype brings with it two new technologies - a rear-wheel drive hybrid system and a parallel-powertrain hybrid system.

The hybrid will use Nissan's own originally developed technology and its first rear-wheel drive hybrid powertrain.

The parallel-powertrain system will comprise of an energy-optimising mechanic with two clutches. One motor is directly connected to an engine and transmission via two separate clutches. The motor switches between the two as driving conditions change, optimising and conserving energy utilisation and improving fuel efficiency.

Nissan believes this will eliminate the need for torque converters, leading to an improved driving 'feel'.

As for the lithium-ion battery itself, they offer superior performance and reliability when compared to conventional nickel metal-hydride ones. Twice the electric power is generated due to the compact laminated configuration as well.
