Nissan has unveiled today first details of its all-electric and hybrid electric prototype vehicles, both incorporating breakthrough technologies.

As part of their aggressive Nissan GT 2012 business plan to become a zero-emission vehicle leader, Nissan has unveiled today first details of its all-electric and hybrid electric prototype vehicles, both incorporating breakthrough technologies.

Nissan's all-electric vehicle is front-wheel drive 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. Nissan plans to introduce the all-electric vehicle in 2010 and mass market globally in 2012. It will have a unique body style not based on any existing Nissan model.

Nissan has also revealed, with little detail, their Hybrid Electric Vehicle (HEV) which showcases two breakthrough technologies. Not only is the HEV the first rear-wheel-drive hybrid, but it also utilizes a parallel-powertrain system which places the electric motor directly connected to the transmission and engine. Depending on driving conditions the electric motor through two separate clutches is powered separately or together by Li-ion battery or fuel engine. As a result, the parallel-powertrain hybrid system eliminates the need for conventional torque converter, 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.

Via the Nissan-NEC joint-venture, known as AESC (Automotive Energy Supply Corporation), both electric and hybrid prototype vehicles are powered by advanced lithium-ion batteries. Their compact laminated configuration not only offer reliability, safety, versatility and cost competitiveness, compared to the conventional nickel metal-hydride batteries but also offer superior performance by delivering twice the electric power.
