Five Reasons to Consider Electrification

Most people in the on-highway transportation industry have heard electrification is coming to commercial vehicles (CVs), and while it is still application dependent, everyone seems to have an interest in electrification of their fleet.

This article outlines five reasons to consider electrification for your fleet.

1. Electrification of medium- and heavy-duty vehicles has arrived and the technology is already on the road. 

Newly released test models of commercial school and transit bus, refuse, drayage and delivery vehicles from several different OEMs have been on the road in the U.S. and the rest of the world for over a year, collecting thousands of miles of data and real-world experience. These tests are allowing OEMs and fleet customers to stay ahead of the competition and refine their technologies in advance of widespread adoption. Fleet owners, partnered with OEMs, are learning about the impact of reduced fuel costs and lower noise along with route optimization to better understand vehicle range under different conditions. These fleet owners are no longer on the bleeding edge of technology, but the leading edge of a transformative change in their business.

Allison Transmission, who has been making the electric - hybrid H 40/50 EP^TM for city bus applications since 2003, has a number of these OEM tests underway utilizing its traditional 3000 and 4000 Series^TM transmissions operating with an electric motor in commercial applications. The advantage of the Allison is that it multiplies the torque providing for faster acceleration from the electric motor and more energy efficiency.

Battery technology also continues to advance, allowing for increased range, reduced weight and more compact integration. Medium-duty commercial battery electric vehicles (CBEVs) may not suit every market or application, but they are a viable alternative in daily return-to-base urban applications of fewer than 100 miles per day. While the projection of electrified commercial vehicles is only expected to be at 12% in the U.S. by 2025, the technology is here to stay.

2. Significant progress has been made in power and torque.

One of the latest advances in commercial electrification is Allison’s new e-axle. The AXE Series is one of the most powerful e-axle systems for medium- and heavy-duty trucks in the world. It’s a fully integrated electric powertrain system designed to fit inside a standard frame along the axles of commercial trucks. The system integrates single or dual electric motors, a multi-speed gearbox, oil coolers and pumps, eliminating the need for additional driveshafts and support structures. This allows the AXE Series to be a bolt-in solution by design, ensuring efficiency in the installation process. This also means that newly electrified vehicles can be on the road in very little time.

A dual-motor axle has a continuous power of 536 horsepower (400 kilowatts) and peak output power of 738 horsepower (550 kilowatts). A tandem axle configuration (6x4) is also available for these vehicles. The system can handle 100% torque in regenerative braking. The complete integration of the AXE Series delivers increased efficiency and continuous power through superior internal cooling.

3. Federal and state regulations reducing greenhouse gas and other emissions increase in 2021.

As most fleet owners are aware, Phase II of the Environmental Protection Agency’s (EPA) greenhouse gas (GHG) and NOx reduction requirements take effect in 2023 and California’s regulations tighten up in 2021. Currently, ten states have adopted California’s zero-emission regulations, according to the North American Council on Freight Efficiency (NACFE). Additionally, several European cities have adopted zero-emission zones in city centers to reduce air and noise pollution. Trends in more fuel-efficient engines and transmissions have helped fleet owners meet the current standards and will help them as new regulations take effect, but electrification may be able to reduce fleet emissions and increase fuel efficiency in a much more significant way.

With zero emissions and no fossil fuel, even a small number of electrified commercial vehicles can have a large impact on a fleet’s overall emission output and fuel consumption. Some states in the U.S. will not register vehicles made before 2013 in the near future, now is the time to plan for phasing out these vehicles, and electrification should be considered along with the latest fuel-efficient pure electric, hybrid, Flex EV, or alternative fueled engines and components.
