Cummins unveil their Fully Electric Class 7 Truck

Diesel engine manufacturer Cummins have unveiled their own electric truck concept at a recent event at the Cummins Technical Center in Columbus, Indiana. Cummins’ new truck, called the AEOS, is a fully electric class 7 Urban Hauler Tractor. The 18,000-lb truck has a maximum payload capacity of 44,000 lbs, and a range of 160 kms, enabled by a surprisingly small 140 kWh battery pack.

With the unveiling of the Concept Class 7 Urban Hauler EV, Cummins introduced a state-of-the art battery pack offering, redefining energy-efficiency and density capabilities for the EV market. The lighter, denser battery design allows it to hold a longer charge for improved range and faster charging, reducing down time. Cummins believe their battery design allows it to hold a longer charge for improved range and faster charging, reducing down time. The company also claims that the AEOS can be fully charged in an hour plus it will be available with an optional diesel range extender to add an extra 320 kms of range.

The concept truck design includes an Engine-Generator option for extended range capabilities, allowing users to benefit from Cummins B4.5 or B6.7 engines, providing a major advantage over today’s hybrid systems. These engine options offer 50 percent fuel savings compared to today’s diesel hybrids with zero emissions.

When you have a global leader in diesel engine production releasing an electric truck concept you know that the future is electric…….

Here are five cool things which Cummins believe that the AEOS might mean to their customers, the environment and the concept of electrification.


The demonstrator truck uses a 140 KWh battery pack instead of a 12-liter engine. The weight of the electric powertrain is roughly equal to that of the removed engine, aftertreatment, transmission and fuel tank. The tractor day cab when paired with a trailer has a gross vehicle weight rating limit of 75,000 pounds. The concept truck has a range of about 100 miles on a single charge for city driving that’s extendable to 300 miles with additional battery packs. The powertrain and truck will enable Cummins to learn more about the potential electrification holds for larger vehicles.


A regenerative braking system and the potential for solar panels on the trailer roof can send energy to the battery pack. Air drag is reduced by replacing side mirrors with an in-dash camera system. The truck achieves a significant air drag reduction via its highly streamlined design as well as a better sealed truck body and underbody – with no front radiator intrusion.


Like Cummins’ diesel, natural gas and alternate fuel products, the concept powertrain and truck are designed to limit the vehicle’s impact on the environment. Electric cars and trucks produce zero emissions, which is important at a time when climate change is such a big concern. If the charging power is generated from 100 percent renewable sources, then the truck can be described as fully carbon neutral.


Cummins wants to be the global leader in powertrains, offering customers a variety of power solutions to meet their particular needs. Diesel engines aren’t going away. The company expects diesel to be a popular option with customers for years to come. Cummins has and will continue to produce the cleanest diesel engines in the world, reaching near zero emissions levels.


Cummins has been meeting the power needs of its customers for nearly 100 years, whether by diesel, natural gas, electrification or something else. The company’s technical staff of 10,000 people around the world has the high tech tools to study everything from a variety of bio fuels to waste heat recovery and even solid oxide fuel cell technology to power the next generation of Cummins’ engines and related products.
