(EV Track) Electric vehicles are gaining a great deal of attention in the commercial vehicle sector because of the potential advantages they offer for improved energy efficiency, reduced emissions, and national energy security. EV adoption, however, does present fleet managers a number of challenges, not the least of which is “how to you measure and compare EV energy consumption to conventionally powered trucks and tractors?”
 
The spectrum of electric vehicle solutions for commercial applications covers a wide range, depending on the vocation and vehicle class. Class 3-6 applications may use hybrid electric or plug-in hybrid electric or allelectric (battery-electric) systems. Larger applications may be all-electric or hydrogen-hybrid electric. We’re all familiar with miles per gallon (MPG) as a common yardstick for comparing fuel economy, but how does it work with EVs?

Energy efficiency for hybrids, plug-in or otherwise, is often measured in terms of miles per gallon of gasoline equivalent (MPGe) but kilowatthours (kWh) per 100 miles is also used. Other metrics include miles per kWh or kilometers per kWh.

Actual energy consumption performance depends highly on the load being carried and the duty cycle experienced, much as is the case with conventionally powered vehicles. However, the power curve to “empty” is not as linear with battery-electrics – that is, the drop off in available energy may greater he closer the battery loses charge.
 
Attend this session and learn all about the various metrics you’ll be using to measure your EV fleet energy consumption performance. It’s not as straight-forward as you think.
