Perfecting an All Electric Powered Bus is NO Easy Feat!

The Proterra all electric public transit bus

All Electric Powered Bus – ( Solar Thermal Magazine)

Electric vehicle design is more challenging the bigger the vehicle you are trying to electrify.  A larger heavier vehicle requires more power to allow it to accelerate and reach speed which in an electric design must be provided from many banks of batteries all of which add to the weight. These vehicles must be able to go up steep grades be able to travel long distances without recharging

New advances in battery technology has resulted in improvements in what is known as energy density or the energy provided for the weight of the cells.

Recently one company, Proterra Inc., has launched a new extended-range product line named as the TerraVolt™ XR extended-range battery. With this new battery, Proterra buses can be configured to travel up to 180 miles between charges.
