Next-generation versions of its hydrogen fuel cell engines, a high-efficiency eAxle, and its next-generation batteries among the new products Accelera by Cummins unveiled at the Advanced Clean Transportation (ACT) Expo on May 20 in Las Vegas.

More Powerful Fuel-Cell Engines

The latest generation of Accelera's fuel cell technology can be found in the FCE300 and FCE150 fuel cell engines.

Both offer increased power density for larger systems, improved system efficiency and advanced durability. The modular architecture allows for a multitude of applications and layouts, while streamlining integration processes for on- and off-highway mobile and stationary applications.

Accelera’s 300kW fuel cell engine will be on display at ACT Expo, in addition to a Navistar RH International Class 8 heavy-duty truck equipped with two rail-mounted FCE150 engines and Accelera’s newest eAxle. This clean-power configuration showcases the connectivity and versatility of Accelera’s offerings.

EAxle Technology Advancements

The next-gen 14Xe is Accelera’s newest and most versatile eAxle, featuring increased energy efficiency.

Available with a 3-speed twin-countershaft or a 2-speed planetary transmission, the 14Xe is designed to accommodate increased torque, power and battery voltage requirements.

The new 14Xe also minimizes the need for wheel-end reductions, making it a more flexible option for customers.

For an enhanced electric drivetrain with an increased focus on functional safety and cybersecurity, the 14Xe is equipped with Accelera’s ELFA 3 V3.2, a high-power inverter.

The 14Xe is best suited for heavy-duty 6x4 applications in a tandem configuration or as a single application for medium-duty and school bus applications.

EV Battery Innovations

Accelera's BP104E is its newest and most flexible battery platform. This next-gen lithium iron phosphate (LFP) platform is highly modular and can adapt easily to different customer needs, providing long life and fast-charging capabilities.

With a rated energy capacity of 104kWh and a max voltage range of 830V, the BP104E is “engineered to redefine energy storage standards along with unparalleled performance, reliability and safety to meet the evolving demands of the transportation sector,” touts an Accelera news release.

The next-gen LFP chemistry composition and cell-to-pack architecture also make it more energy dense and cost competitive.

Volume production of this battery is planned for 2027 with locally manufactured cells in the U.S.

Accelerating the Shift to Zero Emissions

Also on display at ACT Expo are:

• The BP97E nickel manganese cobalt (NMC) battery pack

• The BP107E LFP battery pack

• The 1 CS2002 high powered, remote-mount, direct-drive traction motor.

Many of these products can be easily integrated into existing commercial vehicles or paired with other Accelera products, according to the announcement.
