Cummins Outlines Plans For Electric Powertrains By 2019


Cummins is more than aware of the ongoing electrification movement, and has announced a further R&D developments to become a serious supplier of electrified powertrains for the next generation of plug-ins.

Above: The system consists of a gen-set (Cummins’ Euro 2019 B4.5 internal combustion engine coupled with TM4’s LSG130 electric generator), an external ultrafast charging infrastructure, a power collector, a 111 kW-h onboard Li-ions battery, a TM4 SUMO electric motor directly connected to the axle’s differential, a small fuel tank and all power electronics and controls that allow the system to work.

The most recent announcement comes right after a deal with TM4 on the joint development of a plug-in hybrid powertrain for Class 7/8 transit buses.

In a statement on how it will transition to future technologies, Cummins said that from 2019, the company be supplying both all-electric and plug-in hybrid powertrains.

Cummins already has the know-how in electrical power generation systems on its own, but we figure will probably will again engage a partners in the venture (as with TM4 earlier):


Earlier this year, Cummins enhanced its efforts to commercialize its electrification capabilities, bringing together Cummins knowledge and significant experience in the electrified powertrain space. In addition, the Company is exploring potentially partnering with others to ensure development of leading technology in energy storage, power electronics, traction motor systems and component control for commercial applications. Cummins will begin electrified powertrain delivery in 2019, including battery electric and plug-in hybrids. These are just the first steps as the Company signals its intention to be the leading provider of electrified powertrains in our commercial and industrial markets.”

Tom Linebarger, Cummins Chairman and CEO said:

Skoda Citijet“As a global power leader for the commercial and industrial markets we serve, we are better positioned than any other company to win in new and emerging technologies. Over the past 100 years, our ability to innovate and adapt has fueled our success and we are confident we are on the right path to do it again at this critical juncture. We are prepared to provide a range of power technologies to our customers from diesel and natural gas to fully electric and hybrid powertrains to ensure they always have the best solution for their application.”

Directly connected to the differential looks like a waste of mechanical energy and another part to break. Is this common in the BYD and New Flyer buses?

What part would you remove to address the ‘directly connected to the differential’ problem? Seems to me they are removing the clutch and simplifying the drivetrain.

Good for maximizing regen I would think since electric motors don’t use friction as a *feature* like combustion engines do.

I’d put drive to each wheel for something this size.

Another step towards electrification.

It’s going to be interesting see how electrification picks away at the truck industry.

Reduced noise pollution is another big benefit of electric or PHEV buses and delivery trucks.

Delivery trucks and buses is where we can make some real gains in oil consumption reduction and cleaner air.

feeling the heat from the tesla semi and the analyst downgrade lol

We have surpassed 410 ppm of CO2, Cummins needs to move with more alacrity.

I actually kind of admire Cummins. Rather than fight the made their latest diesel engines a lot cleaner. Given the street cred Cummins has I think they could really help bring electrification to the full size pickup and larger size vehicle market. Until batteries get an order of magnitude less expensive diesel hybrids will be needed for this market in my opinion.
