JLR & Wolfspeed announce strategic partnership
Jaguar Land Rover and Wolfspeed have announced a strategic partnership for the supply of silicon carbide semiconductors. The technology is expected to increase powertrain efficiency and range for JLR’s next-generation electric cars from 2024.Weiterlesen
Cree rebrands to ‘Wolfspeed’ & announces cooperation with GM
Cree, a manufacturer of silicon carbide semiconductors, has renamed itself Wolfspeed. Under the new name, the company has also entered into a cooperation agreement with General Motors. The agreement provides for the development and supply of silicon carbide semiconductors for GM’s future electric cars.Weiterlesen

ZF, Porsche, LG Chem, Eberspaecher, Wolfspeed.
ZF and Porsche together developed a new 8-Speed dual clutch transmission for sports vehicles. The modular hybrid transmission kit works for rear-wheel and all-wheel drives. It was possible to integrate a 100 kW hybrid module without increasing the length of the transmission as compared to the current 7DT sports transmission. The 8DT will first be used in the Porsche Panamera.
LG Chem to grow in China? News of the Koreans expanding their battery production in Michigan are echoed in China. Apparently LG Chem plans to grow its facility in Nanjing, Business Korea learned. Already the factory can produce enough cells for 50,000 EV and 180,000 PHEV a year.
Control platform for e-buses: Eberspaecher Suetrak developed E-Control, a platform that provides centralised control of all thermal management components on-board an electric bus. The tool is compact and can be retrofitted at any time.
No to Infineon: Cree Inc said it would terminate a deal to sell its Wolfspeed division to German chipmaker Infineon, citing security concerns raised by the U.S. government recently. Both companies failed to find a way to work around said issues.
Wolfspeed, India, UCR.
Reducing inverter losses: Wolfspeed has introduced a new 900 V, 10 mΩ MOSFET, which is for 196 A of continuous drain current at a case temperature of 25 degrees Celsius. The silicon carbide (SiC) MOSFET is said to allow for a reduction of EV drivetrain inverter losses of about 78 percent based on EPA mileage standards.
India pitches in: The country’s government says it will foot 60 percent of the bill for research and development projects in the field of electric mobility. Launching the Technology Platform for Electric Mobility (TPEM) is said to especially push projects concerning Li-ion batteries, electric motors, charging infrastructure, light construction, and transportation concepts in the country.
Connectivity as fuel saver: Engineers at the University of California Riverside (UCR) have developed a new online energy management system (EMS) for plug-in hybrids. Using real-time information about i.e. traffic or road conditions and an evolutionary algorithm (EA) to optimise fuel consumption, the latter can be reduced by more than 30 percent.
GAC, Nissan Arc, Semcon, Wolfspeed.
GAC plans big: The Chinese GAC manufacturer announced that it will introduce both purely electric and plug-in hybrid models this year, followed by another seven models in the future. A clear timeline was not given, but GAC says that it wants to sell 200,000 alternative drivetrain vehicles by 2020.
Better batteries: Together with Japanese research institutions, Nissan Arc has developed a new atomic analysis methodology of amorphous silicon monoxide. The compound is often seen as a key to create the next generation of Li-ion batteries, as it does not deteriorate during charging cycles.
Electrified bicycle: Semcon presents its the new light and compact bike motor that turns any bike into an e-bike. The retrofit kit boasts 150 kW and weighs just about one kilo, providing enough power for about 5 km. Moreover, the extra boost is said to cost riders less than 100 euros.

Powered up: The new all-SiC commercial power module from Wolfspeed is designed to offer high efficiency and power density for EV components such as converters and inverters. Efficiency is said to reach 98 percent, allowing the module to be 67% smaller and offer 10 times more power density than systems with conventional silicon IGBT modules.
