ePower’s Series Hybrid Drive – Unmatched Fuel for Heavy Trucks


Over the last couple there’s been a lot of message chatter about ePower Systems, a transportation technology that has selected the PbC® from Axion Power (AXPW ) for its series hybrid drivetrain for over-the-road freight who drive heavy Class 8 Since I introduced ePower to and have tracked their for a couple years, I called CEO Andy Claypole to ask his permission to what I’ve learned ePower’s hybrid electric

After a series of phone and e-mails, Andy graciously me a technical presentation on ePower’s hybrid drive and gave me to share the presentation with and discuss ePower and its technology in detail. Click here to a copy of ePower’s presentation.

ePower Engine Systems LLC is a advanced transportation technology that’s using inexpensive components to bring series drive, the mainstay of the nation’s transportation system, to highway Their goal is to narrow the efficiency gap between 480 ton miles per for railroads and 110 ton miles per gallon for trucks.

In a truck with electric drive, there is no connection between the engine and the Instead, the engine powers a and electricity from the generator an electric drive motor. configuration maximizes fuel by running the engine at its optimal RPM and the need for complex heavy transmissions while delivering the peak torque of an electric

In furtherance of their goal to fuel efficiency, ePower series electric drive a further by sizing the generator for vehicle state operations at speed and using an array of 52 PbC to provide additional power for and hill climbing, and increased savings from regenerative The ePower drivetrain is a true hybrid electric drive and a for the trucking industry. The design is for mountainous routes with elevation changes, but it’s efficient in flatter terrain.

While a typical Class 8 operating in the US with an 80,000 gross vehicle weight fuel economy in the 5.2 mpg range, the truck with an ePower will deliver fuel of 10 to 14 mpg, values that the DOE’s 2018 SuperTruck of 6.8 mpg for conventional heavy trucks. It out to an annual fuel savings of 11,500 gallons per vehicle.

the startup phase, ePower has on the retrofit market because 37% of the 2.7 million trucks in the US-fleet are than five but less twelve years old. trucks have outlived original drivetrain warranties and are less efficient than trucks, but they have remaining useful life in chassis, bodies and other

The cost of converting a tractor a conventional diesel drivetrain to a hybrid electric drivetrain is $70,000 (batteries included) and believes its retrofits will pay for through fuel savings in 18 to 24 months.

Currently, ePower is all required retrofit work in its own Once its system is fully and proven, ePower intends to the necessary conversion components in kit for sale to certified installers fleet operators and other entities. It also hopes to its technologies and systems upstream the OEM market.

ePower’s original used absorbed glass or AGM, batteries to provide and hill climbing boost. the AGM batteries were poorly to long-string use and ePower was not satisfied the frequency of battery failures. The AGM also tended to degrade which impaired acceleration and climbing boost while the efficiency of regenerative braking ePower believes the long-string and high dynamic charge of Axion’s PbC battery will both of these challenges.

The PbC batteries were delivered to in mid-November and installed in swappable boxes that will ePower the ability to switch and forth between the old AGM batteries and the new PbC in a couple of hours. During the week in December, ePower to conduct a series of benchmarking to compare the on-road performance of the two systems in the same vehicle. It then devote the rest of to a road show for potential

In early January, the first PbC truck will be delivered to customer and a second AGM powered will be brought back the shop for a PbC upgrade.

I believe the ePower system is for several reasons. Firstly, a frontal assault on fuel the biggest expense burden in the industry. Secondly, ePower’s marketing efforts are directed at to large fleet operators who are inclined to assume the risk of an idea in real world instead of devoting years to work.

Thirdly, the ePower is an extremely efficient use of batteries. it doesn’t take much penetration in a million-unit fleet to a substantial revenue base for and Axion.

If results from prototype demonstrations are favorable, is a significant likelihood that large freight operators purchase multiple retrofits for testing programs to determine series hybrid electric would fit into their ePower’s series hybrid drive system is not a silver solution for all truckers and all routes, but the can be very compelling for firms established routes and schedules a series hybrid electric can do the required work at a lower
