3 methods to achieve driving range for daily commute

Higher energy density in the batteries

Use of dedicated EV platform

Specially designed platform:reduce aerodynamic drag

When the EV slows down, the computer

coordinates control of the brakes andmotor to optimize energy regeneration.

Generate power with energy capturedwhen vehicle is slowing down

Pre-set air-conditioner:

conserve energy during drive

Higher storage capacity thandifferently-shaped batteries ofthe same size

Nissans EV technologies cut energy consumption.

The range map contributes todriving confidence anytime.

Set the timer to start charging at night totake advantage of lower night-timeelectricity rates.

IT support (1) Peace-of-mind with range display and automatic charging-station

updates.

The timer function helps ensure the car is fully-charged and the

cabin is at a comfortable temperature before the trip.

Automatic updates on chargingstations for the latest information.

Preset the air-conditioner whilethe vehicle is plugged-in to savebattery consumption

IT support (2)

The charging system can be switched ON/OFF and settingthe AC timer can be set by remote control.

Message alerts are sent to cellular phones upon charging completion.With this drivers can use their time shopping or eat-out while charging.

Twice the energy performance The new battery achieves twice the energy density compared to

conventional batteries, owing to to better electrode material and lamination. Higher energy density makes the battery lighter and smaller.
