The Run on Less – Electric demonstration showed that for four market segments — vans and step vans, medium-duty box trucks, terminal tractors and heavy-duty regional haul tractors — commercial battery electric vehicles (CBEVs) are a viable option for fleets. This report’s conclusions were generated through data collection and calculations from Run on Less – Electric. Twelve of the 13 vehicles were equipped with Geotab devices that tracked daily range, speed profiles, state of charge, charging events, amount of regenerative braking energy recovery, weather and number of deliveries. Data for one fleet was collected via the OEM’s own telematics device. RoL-E demonstrated that for four market segments — vans and step vans, medium-duty box trucks, terminal tractors, and heavy-duty regional haul tractors — the technology is mature enough for fleets to be making investments in production CBEVs. Continuous improvement is expected to be rapid as these technologies gain market share. The environmental benefit of reduced CO2 and particulate emissions is significant for replacing traditional diesel and gasoline-based vehicles.
