Nissan previewed the next generation of environmental vehicles at the Nissan Advanced Technology Week, with the unveiling of a range of all-electric and original hybrid electric prototypes powered by advanced lithium-ion batteries. Other highlights included the presentation of an All-Around Collision Free prototype and of the world first eco pedal to help reduce fuel consumption, as well as the next generation fuell cell stack with doubled power density.
Electric Vehicle (EV)
Nissan Denci Cube
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)
Hybrid Electric Vehicle Prototype
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.
ECO Pedal
Eco Pedal
ECO Pedal – a world first technology – designed to assist drivers to become more fuel-efficient. When the eco-pedal system is on, each time the driver steps on the accelarator, a counter push-back control mechanism is activated if the system detects excess pressure, helping to inform the driver that they could be using more fuel than required. An eco-driving indicator integrated into the instrument panel feeds the driver with real-time fuel consumption levels to help improve his/her driving behavior. The ECO Pedal system can be turned on or off according to the driver’s preference.
Nissan plans to commercialize the ECO Pedal during 2009. Research conducted by Nissan has shown that by using the ECO Pedal drive system, drivers can improve fuel efficiency by 5-10%, depending on driving conditions.
