Electric vehicles

Silicon carbide (SiC) and gallium nitride (GaN) are the new kids on the block when it comes to semiconductor power devices. Comparatively, traditional silicon has limitations in high temperature and high voltage operation, limitations important to overcome in the continuous grind for ever greater vehicle range and performance. In electric vehicle power electronics, SiC MOSFETs currently have a much greater presence than GaN HEMTs - why?

General Motors President Mark Reuss has revealed GM's group of three all-new motors that will power its Ultium-based EVs. Designed by GM, the 180-kilowatt front-drive motor, 255-kW rear- and front-drive motor and 62-kW all-wheel drive assist motor are part of Ultium Drive. All three motors were calibrated in-house to ensure the highest level of performance in Ultium-based EVs. The motors were built as a scalable family, sharing design principles as well as similar tooling and manufacturing strategies.

TE Connectivity held a webinar recently to discuss their new product Tendur for surface plating charging connectors. Tendur is an ultra anti-abrasion surface coating for high voltage charging inlets and is a promising technology to improve the lifetime performance of high-powered charging connectors.

In this article, IDTechEx explores the emerging links being forged throughout the electric vehicle power electronics supply chain, with insight into market leaders and supply for emerging silicon carbide devices.

Company's proprietary platform of advanced materials will enable a safer EV battery with higher gravimetric energy density than conventional lithium-ion and solid state technologies

Semiconductors are the lifeblood of the modern age. From your watch to a washing machine, everything these days seems to be 'smart', 'connected' and therefore enabled by semiconductors. Unsurprisingly then, a massive shortage of chips present 'across all categories', according to some industry executives, is having a profound impact.

Airbus has announced plans for a new CityAirbus as the emerging Urban Air Mobility market begins to firm up. Ushering in the next generation of CityAirbus, the fully electric vehicle is equipped with fixed wings, a V-shaped tail, and eight electrically powered propellers as part of its uniquely designed distributed propulsion system. It is designed to carry up to four passengers in a zero emissions flight in multiple applications.

Electric vehicle battery packs have increasing requirements concerning their thermal runaway mitigation strategy. Meanwhile, the aerogel industry is overly dependent on oil & gas and in need of diversification. Could this be the perfect match between a problem looking for a solution and a solution looking for a problem?

No one complained about gasoline cars going much further than you would ever drive. As people got used to them, it was realized that long-range means less hassle. With electric cars, the argument is even stronger. Long-range saves you money.

Energy storage is a key enabler for the ongoing electrification of carbon-intensive sectors, namely the automotive and energy industries. Developments in energy storage are driven by the increased uptake of EVs and the balancing of renewable electricity grids to provide power during low solar and wind periods.

26 kilometers (16 miles) between Greifswald and Wolgast - that is the distance over which Wingcopter drones recently transported blood samples in the Northeast German federal state of Mecklenburg-West Pomerania.

Offering a sleek design and premium passenger experience, a radically simple fault-tolerant system with redundant levels of safety and reliability, an airframe-parachute, and hydrogen as its fuel source, Skai is poised to be the safest, cleanest and most versatile air mobility solution. A key part of Skai's innovation is the use of clean, zero-emission hydrogen fuel cells for its power source.

Candela is a Swedish startup with a game-changing hydro-foiling boat capable of vastly improving range. Are they the Tesla of the sea? IDTechEx caught up with the company to find out.

Forsee Power are a battery manufacturer focussed primarily on supplying commercial vehicle segments.

Headquartered in the US, Microvast are a Li-ion battery manufacturer with capabilities in cell and pack development.

The first phase involves testing of the Nikola Tre BEVs at the port for transport and logistics operations together with high-performance charging solutions. A more definitive second phase in the project partnership plans to see the full integration of the BEV vehicles in port operations, installation of charging infrastructure and on-site service support including major suppliers.

In this premium article, IDTechEx introduces the topic of power electronics in electric vehicles and explores why innovations in this field will be an important differentiator for automakers as the market matures.

Founded in 2001 by e-mobility pioneers, Tritium designs and manufactures proprietary hardware and software to create DC fast chargers for electric vehicles.

The new IDTechEx report, "Autonomous Cars, Robotaxis & Sensors 2022-2042", discovers that level 3 autonomous vehicle technology has been ready since 2017- so where are the autonomous vehicles? The answer lies in unclear liability rules, which have turned out to be a massive headache for automakers like Audi, Tesla, GM, Mercedes, and others.
