Electric trucks prepare for delivery

Plug-in technology isn't just for passenger cars, anymore.

When it comes to electric propulsion, commercial trucks have two big advantages over ordinary passenger vehicles.

First, because of their size and shape, it's easier to add large battery packs. Second, delivery trucks tend lead fairly routine lives, driving roughly the same distance each day and returning to a garage where they can be recharged each night.

So it shouldn't be surprising that several companies are now, once again, getting into the market for electric trucks.
