...The pumper, assigned to Engine 8, is built on a Pierce Enforcer cab and chassis and built with Pierce’s new Volterra technology in collaboration with parent company Oshkosh.
For more than 25 years, Oshkosh has manufactured electric drives for military and various industries and has refined them for emergency vehicles, Pierce President Jim Johnson said....
...The rig was customized for Engine 8’s response district, where the average response is four miles roundtrip for emergencies.
Developed by Oshkosh, the parallel-electric drivetrain features an electro-mechanical infinitely variable transmission that allows for zero-emissions using the integrated onboard batteries. The rig also features an internal combustion engine that provides uninterrupted power for extended operations.
The electric power comes from a 155 kW hour lithium-ion battery pack capable of powering the rig for 37 miles. Should there be a major fire where the rig will be pumping for an extended period of time, the truck will monitor the battery level and automatically transfer over to the internal combustion engine....

...An Oshkosh patented parallel-electric drivetrain featuring an electro-mechanical infinitely variable transmission allows zero-emissions operation when powered by the integrated onboard batteries.
The chassis will operate under electric power in all normal operational situations and will leverage the internal combustion engine for backup power in extended emergency operations...
...Standardized Pierce pumping configurations, up to 2000 gpm, are driven through the electric driveline and are powered by either the integrated onboard batteries or the internal combustion engine.
The driveline allows for zero emissions during quick attack responses, and has the ability to transition seamlessly to internal combustion power for extended pumping operations. ...
