China is aggressively moving towards EV sales. If they continue down this path, all of the out year estimates for SiC sales should end up low.

I do remember seeing something in a tech publication a couple years back (EE Times or the like) about BYD and SiC technology so I just assumed Cree. Could very well be another player? Sorry for being vague - coffee hasn't kicked the old motor into gear yet :-)

To: Lou Weed who wrote (9901) | 11/16/2018 8:20:12 AM | From: slacker711 | | | FWIW, this is the one mention I see on the thread.
SiC is an automatic f the battery is of sufficient size on an EV.
Message 31583375
Also, China's electric car maker BYD shows keen interest in developing SiC power devices, and international IDMs are proceeding with fast deployments in high-performance SiC power devices needed for new-energy cars now under development by major auto brands in the US, Europe and Japan, the sources indicated. |

From: slacker711 | 11/16/2018 10:30:54 AM | | | | VW board backs plan to storm the market with millions of electric cars Confirms Ford talks, 3-plant plan for EVs — and clears up a big error autoblog.com
ASSOCIATED PRESS Nov 16th 2018 at 9:40AM 1 comments FRANKFURT, Germany — Volkswagen says it will invest $50 billion in developing autonomous and electric cars and expand the appeal of battery-powered cars by selling its upcoming I.D. compact for about what a diesel-powered Golf costs.
Chairman Hans Dieter Poetsch told a news conference Friday that the company's plans for the next five years aim to make Volkswagen "a worldwide supplier of sustainable mobility."
Poetsch says the company is in talks with Ford about possible cooperation in making light commercial vehicles.
Volkswagen is converting three of its German plants from internal combustion to battery car production as it pivots away from diesel vehicles in the wake of its emissions scandal. It says it will increase the number of electric models from six now to more than 50 by 2025.
Volkswagen could build up to 15 million electric cars over several years on its new electric vehicle production platform, the company said — adding that its Chief Executive Herbert Diess had misspoken in an interview on Monday.
Automotive News on Monday quoted Diess as saying that VW could build 50 million electric vehicles globally across its brands, beginning in 2020, and had battery sourcing agreements for them.
A VW spokesman on Friday said that the figure, which referred to a theoretical long-term goal for the MEB electric car manufacturing platform, was overstated.
"Diess meant to say 15 million, not 50 million cars," the spokesman said.
VW's supervisory board voted Friday on the multi-billion-dollar EV investment plan, including steps to retool three German plants to mass produce electric cars and to explore alliances with battery partners and rival carmakers.
Labor unions, who control half the seats on Volkswagen's supervisory board, needed to sign off on the plan to create global production capacity for 1 million electric vehicles by 2025 amid their concerns that assembling battery driven cars will require fewer workers.
Around 436,000 industrial jobs in Germany are tied to building petrol and diesel engined vehicles.
Jobs are under threat because a combustion engined car has 1,400 components in the motor, exhaust system and transmission, while an electric car's battery and motor has only 200 components, according to analysts at ING.
Volkswagen's management this week outlined plans to labor leaders for converting car plants in Zwickau, Emden and Hannover to build electric cars, providing job guarantees to workers until 2028.
The first ID electric car is due to roll off the production line in Zwickau in 2019, as the plant ramps up to a production capacity of 330,000 electric vehicles. Zwickau currently builds the VW Golf and the Golf Estate.
Volkswagen's MEB electric vehicle platform is also being eyed by Ford as the two companies continue exploratory talks about an alliance to develop self-driving and electric vehicles and to complement each other's global production footprints.

From: slacker711 | 11/27/2018 8:00:09 AM | | | | Good to know that there is some interest in private equity for a deal in lighting.

Bain Said to Explore Takeover Bid for Germany's Osram Licht By Ruth David , Sarah Syed , and Eyk Henning November 27, 2018, 3:28 AM CST Updated on November 27, 2018, 4:05 AM CST Shares of Osram soar, taking market value to 3.9 billion euros Other private equity firms are also eyeing the ex-Siemens unit
SIEMENS AG-REG 102.08EUR-0.74-0.72% Bain Capital is exploring a takeover bid for German lighting-products manufacturer Osram Licht AG, which has a market value of almost 3.9 billion euros ($4.4 billion), according to people with knowledge of the matter.
The private equity firm is working with financial advisers in assessing the business, the people said, asking not to be identified because the deliberations are private. Other potential suitors including rival buyout firms are also eyeing the former Siemens AG unit, though the interest may not ultimately result in a deal, they said. Osram shares soared by the most in more than five years.
Representatives for Osram and Bain declined to comment.
Shares of the German manufacturer had plummeted more than 50 percent this year as a slowdown in the lighting business and dampened demand for headlights from global automakers triggered two profit warnings and a muted outlook for the next financial year. The company has signaled its interest in selling two underperforming units -- lighting fixtures and U.S. services -- as it seeks to reorganize operations and boost earnings.
Siemens exited the business a year ago, selling its remaining 17 percent stake in Osram for about 1.2 billion euros.
Osram shares climbed as much as 19.6 percent -- the most since July 2013 -- before trading up 18 percent to 39.82 euros as of 10:56 a.m. in Frankfurt trading.

From: slacker711 | 11/28/2018 7:11:21 AM | | | | Oak Ridge Inches Closer to 15-?Minute Wireless EV Charging But the team must further scale their 120-kilowatt wireless charging system for electric vehicles in order to meet the U.S. Department of Energy’s goal By Mark Anderson
spectrum.ieee.org
snip..............................................
To beam wireless power from a floor unit to a power receiver unit in an EV, separated by some six inches of open air, means rapidly oscillating the electric and magnetic fields in the coil, inducing similar behavior in the receiving coil in the EV. Practically speaking, Ozpineci says, that means pumping out 120 kilowatts through oscillating currents at some 22,000 cycles per second (i.e., 22 kilohertz).
“The problem is typically we have silicon devices, and when we go to higher power levels, you cannot run them at higher switching frequencies,” he says. “At 10 kW, you can switch at 20 kHz. But when you go up to 100 kW and beyond, you have to reduce your switching frequency—because of thermal issues, because of the device response, because of a number of things.”
But transferring higher power levels at high efficiency demands higher switching frequencies. So this effectively means both swapping out silicon for more robust (and more expensive) silicon carbide and strengthening the coils on both sending and receiving ends of the power exchange.
Tesla’s Model 3 also uses silicon carbide electronics, Ozpineci says. So the Oak Ridge technology’s reliance on the material is not unprecedented in EV systems. On the other hand, they admit their 100-pound (45-kilogram) coil needs some refining and optimizing before it could ever be scaled out into a production-quality design.
Then, they must produce three times more power from their design to reach the Energy Department’s 350- to 400-kW target. Ozpineci says it’s a work in progress, but he suspects there will have to be multiple power modules in any 350-kW or more wireless supercharger.
“We’re able to use single power modules,” he says of the current 120-kW unit. “We’re at the limit or almost at the limit of these power modules. When you go to anything beyond that, we’ll have to either parallel these modules, or we have to have two inverters in parallel. And when you do that, you have a lot more challenges of running these things in sync.” |
