BorgWarner electric turbo wins OEM contract

BorgWarner Secures Business Win for its First Mass-market eTurbo™ Application

• Start of eTurbo™ mass production slated for 2022 with major OEM
• Technology enables meeting tighter emission regulations
• More than 200 percent transient boost improvement and a 50 percent reduction in time-to-torque virtually eliminates turbo lag and results in exceptional low-end torque

BorgWarner has secured a contract with a major European OEM to supply its high performing eTurbo™ on a passenger vehicle. This business award marks the company’s first serial production contract for the eTurbo, with production slated to begin in 2022. With the eTurbo’s key performance and energy-usage benefits, BorgWarner is boosting vehicle performance while aiding vehicle manufacturers in meeting more stringent future global emissions regulations, and improving fuel efficiency.

“BorgWarner’s eTurbo is a powerful and efficient solution, capable of delivering crucial benefits for our customers, including improved performance, better fuel economy, reduced emissions and more efficient energy usage,” said Joe Fadool, President and General Manager BorgWarner Emissions, Thermal and Turbo Systems. “We believe this is the largest industry award to date for this type of technology and is an important milestone for our company.”

The eTurbo is comprised of a mechanical turbocharger with an electric motor directly coupled to the shaft which can serve as either a motor or a generator. The integrated solution delivers the traditional benefits of a standard turbocharger with the added advantage of electrified boost assistance for superior response. Additional benefits include the ability to capture excess turbine energy to generate electrical power and reduced emissions through aftertreatment management and precise air/fuel ratio control.

The eTurbo delivers a more than 200 percent improvement in transient boost response along with steady state torque improvement. This enables further engine downsizing, resulting in better fuel economy and reduced emissions with no loss of performance and is especially suited for Miller Cycle engine concepts.

Beyond the vehicle performance aspects, the eTurbo can harvest excess exhaust energy and directly convert it to electrical energy to be used for accessory power or charging the battery, thus even allowing for reduction of battery size. The eTurbo also can help drive on-demand exhaust gas recirculation by increasing engine backpressure to reduce emissions. The electrical function can be turned off to return it to the traditional turbocharger function.

While BorgWarner’s eTurbo is launching on a passenger vehicle, BorgWarner anticipates opportunities for future adoption in the commercial vehicle sector as well. The company has a range of eTurbo offerings, including full-performance 48-volt and high voltage compliant architectures. Additionally, customers have the choice of integrated or semi-integrated power electronics.

Looks interesting, I notice that Turbosmart has just released an electronically controlled wastegate to control boost also.

Sounds like F1 tech for the road.

And people say F1 is not worth it

What are its power requirements?
Will this be a bolt on feature for a standard car with 12v, or onloy on hybrids where higher voltage is available?

People have played with electrical chargers for decades, but the drawback has always been the power needed to get it up to speed., necessitating massive current draw at 12v, and guaranteed to fry your battery.

I doubt it would be for 12V systems as the current draw will be too high, I'm guessing for 48V systems only.

You were right. Most of them are 48V or higher.

But there is an eBoost (electric supercharger) that comes in 12V version, as well as 48V versions.

It will for sure not be cheap to replace one of the eTurbos.

What on earth has this Australian eBay seller been hacking together in his shed?

Looks like a modified battery power tool attached to half a turbocharger?!

Reminds me of the ZET electric turbo scam, look at the wiring......LOL

Conversely, the Borg Warner electric supercharger looks promising

pffft.. 48v... mate at Penrif doesn't need no 48v nonsense.

Aren't Audi already using them? ie not the B+D version though.

It works differently.

But its not.
The 12v eBooster is a relatively low power supplemental booster, to assist turbocharged engines at low speeds. ie it can provide a very small amount of boost to supplement the turbo whilst its still spooling up.
