During last week, many of us watched Nissan unveil its electric car, Leaf.  Those who where in Yokohoma, Japan for the unveiling had a chance to test drive the vehicle and get a demonstration of the technology behind the vehicle.  Our friends from Tree Hugger were kind enough to bring us a little more than what the rest of mdeia has offered thus far.   In an exclusive article, Tree hugger explains Nissan’s technology demonstration that utilizes the internet technology to interface with its electric vehicles. Check out the exclusive video (via You Tube) and a collection of pictures here.

As you can see in this quick demo, the car sends info to an Apple iPhone via a dedicated global data center. The software tells the user about the car’s state of charge, the cost to charge at a given hour of the day, and sends alerts when it’s fully juiced up.

Nissan also expects this is how drivers may program what times of day they want to charge up. Since tiered electricity billing is becoming more common (especially with the spread of smart meters), customers will want to charge their cars when it’s cheapest.

This smartphone interface also lets the user activate or pre-program the car’s climate control. This is important because heating and air conditioning draw a considerable amount of power, so it’s better to draw from the grid when plugged in, rather than once the car is on the road and running on its battery.

Although this interface isn’t likely to appear on the first-generation Leaf when it comes out in late 2010, Nissan has assured us that this is not just eye candy, and that smartphone connectivity is a feature that will make it to market.
