Are plug in electric trucks possible?

Conventional wisdom is that working trucks and 18 wheelers are too big and heavy for electric batteries. While it might be true that current batteries alone could not power a large truck, they can improve the efficiency. The utility company Southern California Edison has developed a working prototype plug in hybrid truck over 5 years ago. The truck weighs 26,000 lbs with the hybrid system adding 1,000 lbs. They are looking to add another to their fleet.

Another company, Eaton, produces smaller hybrid drive-trains for smaller trucks and buses. They are currently developing plug in hybrid systems for larger trucks. According to Kevin Beaty of Eaton, “The point is, can batteries help improve the performance and fuel economy of an 18-wheeler? Absolutely they can”.

With still high prices for diesel fuel, anything that can improve efficiency of our truck fleet should be on the table. Work on heavy vehicle plug in hybrid technology is still in its early phases, but the development should have benefits for all vehicles down the line.
