Tokyo, Japan – Nissan Motor Company has previewed a prototype of the electric vehicle (EV) platform it plans to bring to market in 2010.
The platform was shown as a prototype based on the Tiida (sold as the Versa in North America). Nissan said that the production version will have a unique design and body, which it will unveil on August 2, 2009.
The dedicated EV platform includes a highly rigid body, high-performance motor, and a compact lithium-ion battery with high power output and energy capacity. The in-house-developed electric motor delivers 206 lb-ft of torque for high response and powerful acceleration, along with unique motor control that contributes to seamless acceleration.
The compact battery pack is located under the vehicle floor for more efficient packaging while retaining cabin and cargo space, and allows smooth under-floor airflow to help reduce drag. A regenerative braking system recharges the battery, extending the driving range to more than 160 km under a full charge.
Nissan has also developed a sophisticated system that connects the vehicle’s on-board transmitting unit to a global data centre. The vehicle’s navigation map shows the driving radius within range under the current state of charge, and can calculate if the vehicle is within range of a preset destination. The navigation system also points out the latest information on available charging stations within the current driving range, and displays detailed information for each station.
A timer function enables the air conditioner or battery charging to begin at a specified timer. The air conditioner can be preset while the vehicle is plugged in, to cool the cabin to a desirable temperature before the driver enters, without taxing the vehicle’s battery. The battery charging can be set to start at a specified time of night to benefit from more favourable electricity rates.
The driver can also monitor the EV’s state of charge via an online website and a cellular phone. When the battery is fully charged, a message alert can be sent to the cellular phone, while the driver can use a range of remote control functions, including switching the charging system on or off, or setting the air conditioning timer.
