Region's expertise in hybrid cars goes beyond high-profile players

September 5, 2009

If electric van upstart Bright Automotive and battery producer EnerDel can deliver product as well as they’ve generated publicity, central Indiana stands to gain thousands of manufacturing jobs.

But drowned out by reports of potential jobs and the millions of dollars in federal funding the two have landed are other companies toiling in the emerging hybrid automotive market, albeit as quietly as the electric motors on a Toyota Prius.

In fact, meld Bright and EnerDel’s lineup with components made by other firms, such as Remy International, Indy Power Systems and Light Engineering, and you’d practically have all the key components for a plug-in vehicle.

“Indiana, interestingly, has probably more assets related to this new energy automotive [sector] than anywhere else I know,” said Scott Prince, a local partner of Philadelphia-based EnerTech Capital.

Pulling out a stack of company brochures from his visits around the state, Paul Mitchell rattles off names of motor makers and electronics firms capable of entering the automotive or wind-energy sector.

“The potential here is even broader than the three or four smaller firms that often get mentioned in central Indiana who have been out there professing their desire to be in this industry,” said Mitchell, president and CEO of Energy Systems Network, an initiative formed early this year to grow the state’s energy technology industry.

Remy International

Few realize, for example, that North America’s largest producer of electric motors for hybrid vehicles is based northeast of Indianapolis, in Pendleton.

Remy International was one of those former General Motors units that shuttered its local alternator and starter manufacturing.

What’s not widely known is that Remy in recent years has been designing and producing electric motors for GM’s hybrid SUVs, such as the GMC Denali and Cadillac Escalade.

Hybrid vehicle sales in the United States could hit 1.5 million in 2012, according to The Green Car Report issued by Santa Monica, Calif.-based MDB Capital Group. With average sales prices of about $30,000, that could amount to $52.5 billion in sales. For hybrid components manufacturers, that would represent sales of $25 billion, the MDB report said.

“We think that in five years this [sector] could be one-third of our sales,” said Remy CEO John Weber.

With such potential in mind, Remy has worked to create a standard line of motors that essentially can be plucked off the shelf for automakers. By avoiding non-recurring tooling and development, Remy hopes to keep prices competitive.

It has already produced more than 50,000 motors for hybrids. Next, it will supply hybrid motors for German automaker Daimler AG. A deal with another automaker is to be completed later this year.

Last month, Remy won $60 million in federal funding to further develop its line.

“We have not spent a lot of time banging pots, saying, ‘Look at us, look at us,” Weber said.

Light Engineering

Neither has Light Engineering.

The electric motor company was started in 1998 in San Jose by a handful of University of California-Berkley students who built motors for GM’s Sunrayce electric car competition.

Nearly a decade ago, straining under the high cost of doing business in California amid the dot-com boom, Light moved operations to the relatively cheap confines of Park 100 in Indianapolis.

Still funded primarily by California venture capital, including that of Silicon Valley real estate tycoon Carl Berg, Light has been creeping into the hybrid market while primarily making electric motors for industrial uses, including power generators it supplies to Marathon Electric for fire-rescue trucks.

Light CEO Matthew Johnston, a Chicagoan, about a year ago struck a deal with Chinese Automaker JAC Motors to make Light the exclusive supplier of motors for its new delivery truck. Johnston’s team spent last April at the Shanghai Auto Show, where JAC had a hybrid truck ready to drive.

A month later, Johnston’s team was in Stavanger, Norway, trying to drum up business for a Light motor unit at the International Electric Vehicle Symposium and Exhibition.

“Everybody is trying to put their stake in the ground,” Johnston said.

Indy Power Systems

Indy Power Systems has more stakes in the ground than a Boy Scout campout.

It’s indicative of the still-emerging hybrid power technology, which the company’s CEO, Steve Tolen, embraced in 2007. By then, he thought the technology and market were ripe for an electric car, and he formed Symphony Motors.

To keep costs down, he wanted the car to be able to use different types of batteries, given that technologies continue to evolve. But nobody made a power control system that could handle different battery chemistries and their wildly different characteristics.

With the help of former GM engineers, Tolen’s firm developed a power control system, known as the “Multi-Flex,” they were happy with. But he and investors saw more potential money in the device itself than in making cars.

“We manage electrons,” Tolen said. “We found it doesn’t matter where they come from.”

Newer battery technologies, such as lithium-ion, are preferred for hybrids because of their higher power and lower weight. Yet they’re markedly more expensive than conventional lead-acid batteries or even the nickel metal hydride batteries used in most existing hybrid cars.

Indy Power Systems’ control device would allow, say a hybrid truck or school bus, to mix cheaper and more expensive battery types in the same vehicle. That way a hybrid could enjoy the advantages of lithium or nickel metal hydride. Besides weighing less, these two more expensive battery types can recapture energy generated when a hybrid’s brakes are applied.

Indy Power is also in talks with customers for other potential applications, such as putting its technology inside a cell phone affixed with a photovoltaic strip to allow charging by the sun.

Tolen’s team is also validating their electronic brain’s ability to manage and blend bigger power, allowing an industrial building, for example, to balance multiple energy inputs—from the grid, from a wind turbine and from solar power.

To that end, in a shack lined with concrete sheets in case things go “boom,” engineers are testing the Multi-Flex’s ability to manage a whopping 300 amps of power—enough to cook King Kong to the size of a hot dog.

And on Sept. 3, Tolen announced that Indy Power, the Crane Naval Surface Warfare Center and Pike Central High School in Pike County will team to equip a Humvee with an electric hybrid drive system.

So far, the six-person firm has yet to sign up a commercial customer, “but we’re reaching a critical mass,” Tolen said.


Battery maker EnerDel, which has its second plant just a 3-wood shot east of Indy Power’s Noblesville office, is already up and running.

It has a letter of intent with California-based Fisker Automotive, which hopes to start manufacturing its sports car hybrid by mid-2010. EnerDel already supplies batteries to Norwegian hybrid maker Think.

EnerDel also has development agreements with Volvo and Nissan that it hopes will lead to big orders some day. It already provides batteries for the Japanese postal system, for a fleet of electric delivery vehicles, “which I think proves we do have some technology that’s very interesting,” said Ulrik Grape, EnerDel’s CEO.

Interesting, indeed, given the lead Japanese companies such as Panasonic and NEC have in supplying batteries for the most popular hybrids. Ford Motor Co. even uses a Japanese battery supplier for its hybrids.

So far, EnerDel is the only hybrid battery company in the United States actually in production.

“We have a lead as we see it here in the United States,” Grape said.

Already, EnerDel envisions a third plant in central Indiana that could employ hundreds. It has applied for more than $450 million in federal funding toward expansion.

Timing is everything

As for other companies in Indiana that could move into the hybrid sector, time will tell, said Mitchell, of the Energy Systems Network.

“The challenge for these companies is deciding when to move into the market. I’m not sure that even I would advise them now is the right time for them to do it. It’s certainly the right time to start thinking about it and perhaps planning for it.”

Mitchell, whose group announced in April the “Hoosier Heavy Hybrid,” a partnership to develop a hybrid truck, noted that there’s still uncertainty about the extent to which automakers will embrace hybrids.

With all the uncertainty, motor maker Light Engineering isn’t ready to put all its eggs into the much-ballyhooed hybrid basket. Having lived through the dot-com bubble, Johnston said he’s well aware a similar scenario could play out in the hybrid realm.

In addition to producing motors for hybrid vehicles, Johnston’s Light Engineering sees huge potential in selling efficient electric motors to the broader industrial market. He notes that about 60 percent to 70 percent of the world’s generated electricity turns motors running everything from water pumps to heating and cooling systems. Energy efficiency is expected to be a huge market, especially with the cap-and-trade plan being contemplated by Congress that could send power prices soaring.

“We really work to not get too pigeonholed” into a market, he added.

Energy-efficiency application “maybe gets drowned out a bit with all the hype over electric vehicles,” he said.•
