Green Options

Nissan have announced plans to roll out a ‘fast charge’ electric car network in Arizona, capable of topping up batteries in as little as 10-15 minutes.

The Japanese company has teamed up with EV charge-tech firm ECOtality and the Pima association of government’s, (representing the Tucson, Arizona region), to establish a pilot-scale network in readiness for the launch of Nissan electric cars in the US next year.

In a slew of announcements this week, a picture of what the future of plug-in vehicle charging might look like is starting to emerge.

The Problem:

There are 54 million garages for the 247 million registered cars in the US, meaning that the majority of cars are parked overnight in parking structures, parking lots or curbside.

As a result, most potential plug-in vehicle consumers do not have an adequate place to charge their vehicles. This problem is even more pronounced in urban areas like San Francisco, where only about 16% of cars are parked in garages overnight and the rest end up curbside or in parking lots.

Also, although the US power grid probably has enough overall capacity to supply energy to a nation of plug-in vehicles, it may not have the ability to charge them when they all plug-in and demand energy at the same time — say 6 pm every weekday.
