Range, already a major player in commercial trucking electrification with its eTrailer System which turns diesel trucks into hybrid-electrics, says that adding ESL's charging solution will help to leverage existing shore power infrastructure and affordable charging hardware to support the transition of commercial trucking fleets to electrics. 

The two companies are slated to shortly begin interoperability testing to ensure seamless integration and optimizing charging efficiency for electrified trailers. Additionally, the agreement calls for engaging with air quality regulators on projects to demonstrate Range's system in real-world operations, along with showcasing the environmental and operational benefits of electrified transport refrigeration unit (TRU) fleets.

For it spart, ESL will provide 480V 3-phase charging hardware for installation at fleet sites. Testing will be conducted in California. 

“Collaborating with ESL represents a critical step towards electric and hybrid-electric commercial fleet operations,” said Ali Javidan, CTO and founder of Range Energy. “By demonstrating the real-world feasibility of affordable alternating current (AC) charging to support electric and hybrid-electric fleet operations, we are proving that practical electrification solutions exist today.”

Since its founding over 30 years ago, ESL has provided over 300,000 electrical connection points globally in several industries aside from commercial trucking.

This isn't the first time Range has entered a trailer partnership. Last February, it inked a deal with ZF for the North American market.

Range's eTrailer includes a modular battery pack, the ZF e-axle, and a smart kingpin equipped with Range's patented control algorithms. Range says the trailer delivers up to $20,000 in projected savings per year and a 70% reduction in emissions using existing equipment and infrastructure.

Hydrogen Fuel Cell & BEV Survey
The following survey was sent as a link in an email cover message in February 2023 to the newsletter lists for Overdrive and CCJ. After approximately two weeks, a total of 176 owner-operators under their own authority, 113 owner-operators leased or assigned to a carrier and 82 fleet executives and 36 fleet employees from fleets with 10 or more power units had completed and submitted the questionnaire for a total of 407 qualified responses. Cross-tabulations based on respondent type are provided for each question when applicable.
