ProTerra Drivetrain

ProTerra drivetrain features two electric motors that enable industry-leading efficiency and greater power characteristics:

A SINGLE 250 kW magnet drive motor known as the ProDrive (pictured above). The standard option for the ZX5 transit bus enabling up to 22 miles per gallon (MPGe) 5x more than a standard diesel bus. ProDrive also enables regenerative braking for the most efficient use of energy while reducing strain on the brakes.

ProTerra DuoPower drivetrain is for commercial vehicles with more demanding condition and tougher terrains such as steep hills, extreme weather, and/or longer routes. The DuoPower provides greater horsepower, 550 horsepower to tackle steep hills with grades up to 27%.

ProTerra Batteries

Industry leading energy density for maximum range. Able to withstand harsh environments. Safe and Reliable. The best batteries start with the best cells. ProTerra Barries are made using cylindrical cells that can handle rapid charging, industry-leading energy density, and heavy cycling. Cells enter the battery pack. Each pack is able to withstand heat, cold, vibration and submersion. In the case of a cell malfunction, the problem is isolated to one specific cell, will not spread to neighboring cells. The design is able to fit any commercial vehicle. They are smart, safe & durable, as well as efficient.

S - Series Batteries

113 kWh of energy storage per pack.

Editor-in-Chief Statement

ProTerra already owns 50% of all electric buses in the United States & Canada. They appear to have great news released almost every week. ProTerra has positioned itself to become a leader during this massive transition to electrify public transportation. Of all the EV Companies, ProTerra is my favorite. I have already invested over $22,000 in (NYSE: ACTC) and believe in huge things for the company moving forward.
