by Range Energy, a manufacturer of truck trailers, has developed a groundbreaking solution that significantly enhances the fuel efficiency of semi-trucks. Their electrified trailer, which can be connected to any standard tractor cab, incorporates electric powertrains that transform regular semis into efficient hybrids. Additionally, the trailers are designed to be easily maneuverable by hand, allowing for convenient transportation at depots.
The technology is compatible with both electric and diesel-powered cabs, making it suitable for fleet operations without requiring any modifications to the trucks. The trailer is equipped with a smart kingpin that detects the acceleration and braking loads exerted by the tractor on the trailer. It utilizes electric motors to provide assistance as needed.
When the cab accelerates and exerts force on the kingpin, the electric motors instantly and proportionally add torque. Conversely, when the cab applies the brakes and pushes against the kingpin, the trailer engages regenerative braking to assist in slowing down.
In fuel economy tests conducted by Mesilla Valley Transportation Solutions, Range Energy reported an impressive fuel economy improvement of 3.25 mpg (72.4 L/100km). This represents a remarkable 36.9% increase in efficiency compared to the standard fuel consumption of the test truck.
Range’s Chief Revenue Officer and founder, Ali Javidan, explained that the achieved fuel economy is equivalent to the consumption when driving a tractor without a trailer, known as bobtailing. The tests were conducted on a 25.5-mile (41-km) urban/highway route at a gross vehicle weight of approximately 59,000 lb (26,760 kg) and top speeds of 60 mph (96.5 km/h). The scenarios encompassed various driving conditions, including stop-and-go and steady-speed segments.
It is important to assess how these results translate to real-world situations, as long-haul trucks typically cover extensive distances at constant highway speeds.
Range Energy’s initial trailers aim for a 40% improvement in efficiency over a range of 200 miles (322 km). Javidan revealed that, under highly loaded city driving conditions, the efficiency boost reaches 48%. The figure drops slightly to 41% for mixed highway and city driving, and slightly lowers for over-the-road long-haul trucking.
Javidan emphasized that, ultimately, the trailer remains a trailer, acting as an escalator that assists in reaching greater heights. However, if any technological aspects fail, it still functions as stairs. The trailer can be charged at either end of its journey, requiring 10.5 hours on an AC connection or as little as 45 minutes using a 350-kW DC fast charger.
Apart from improving fuel efficiency, there are other advantages to using the electrified trailer. Drivers appreciate its lighter weight and enhanced safety features. Furthermore, the trailer responds to engine braking in the same manner it does to the brake pedal, resulting in a more relaxing driving experience when descending hills compared to traditional heavy trailers.
Range Energy also designed the system with future flexibility in mind. For instance, the battery pack can be adapted to power refrigerated trailers. Moreover, the technology has the potential to integrate with other control systems, enabling larger logistics operations to remotely control or autonomously move trailers within certain facilities.
Javidan announced that the company plans to deploy the trailers to its first customers in the current year, with the goal of commencing full-scale production in late 2024. Consequently, these electrified trailers are expected to become more prevalent on the roadways by early 2025.
While the pricing details for the trailers are currently unavailable, it is anticipated that the significant fuel savings offered by the technology will make it a financially viable investment. This innovative solution enables the gradual decarbonization of land transport operations without requiring major infrastructure changes or the replacement of existing trucks. The future developments and impact of Range Energy’s electrified trailers are eagerly anticipated.
