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.
