Tokyo, Japan – Nissan Motor Company has unveiled all-electric and original hybrid electric prototype vehicles, both powered by advanced lithium-ion batteries. The company has committed to zero-emission vehicle leadership under its Nissan GT 2012 business plan, and has announced its intention to introduce an all-electric vehicle in 2010 to be mass-marketed globally in 2012.
The company’s electric vehicle (EV) prototype features a front-wheel drive layout and 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 version, to be introduced in 2010, will have a unique body style and is not based on any existing Nissan model.
The hybrid electric vehicle (HEV) delivers two breakthrough technologies: a high-performance rear-wheel drive hybrid system and parallel-powertrain hybrid system. The hybrid employs Nissan’s originally developed hybrid technology and its first rear-wheel drive hybrid powertrain.
The parallel-powertrain system uses 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 system eliminates the need for conventional torque converters, contributing to higher responsiveness and linear acceleration for improved driving feel.
The lithium-ion batteries used in both prototypes are sourced from AESC (Automotive Energy Supply Corporation), a joint venture between Nissan and NEC. The compact laminated configuration delivers twice the electric power compared to conventional nickel-metal hydride batteries with a cylinderical configuration. The compact batteries also allow for improved vehicle packaging and a wide range of applications.
