Sponsored by AVL High voltage batteries, a key component of electrified powertrains, play a critical role in future mobility concepts. Coupled with one or more electric drives, the integrated propulsion system determines driveability, package flexibility, and other brand-defining DNA. Similarly, the costs and robustness of a battery also contribute to the success of e-mobility. To… Read more »

Be careful what you wish for department: Automakers now say Trump rollback of emissions standards goes too far
The legacy automakers are like a hopelessly lost driver, stuck at a fork in the road with no clue which direction to take. Two days after Trump’s election in 2016, they sent him a letter asking for previously-agreed fuel economy standards to be watered down. The new administration enthusiastically agreed, and began dismantling these and… Read more »
Wildcat Discovery Technologies receives second patent for silicon anode electrolytes
Wildcat Discovery Technologies, a company that uses high-throughput methods to develop next-generation battery materials, has received a second patent on its development of electrolytes for silicon anode batteries. Wildcat’s first patent for this work was awarded in late 2018 and covered the use of sulfolane-based electrolytes. This new patent covers acrylate-based additives which can be… Read more »
VW to install 140 fast chargers at Berlin supermarkets
Volkswagen has partnered with the Lidl and Kaufland supermarket chains, which are owned by the Schwarz Group, to install 140 public charging stations at 60 Lidl and 10 Kaufland locations around Berlin. VW says these 140 chargers will expand the public charging infrastructure in the city by almost 20%. VW is launching an electric car… Read more »
Fraunhofer’s dry coating process for electrodes could make cell production in Europe economical
Researchers at Germany’s Fraunhofer Institute for Material and Beam Technology IWS have developed a new battery cell production process that coats electrodes with a dry film instead of liquid chemicals. This simplified process saves energy and eliminates toxic solvents. The Fraunhofer researchers, with colleagues from Samsung, describe their findings in a new paper, “Overcoming binder… Read more »
Battery testing start-up Novonix has spun off PUREgraphite to manufacture anode material in the US
Batteries are ubiquitous in our modern lives. Take a look around you and count how many items need be plugged in and recharged. If you’re at your desk, the answer might be four or five. If you’re out for a run, perhaps two or three. If you’re in a garage, there may only be one,… Read more »
The Wallbox Copper proves EV chargers can be beautiful too
The Spanish charging station company Wallbox is growing quickly and winning awards. The Red Dot Product Design award is given every year to consumer products with exceptional design, from luxury watches to elegant furniture to stunning sports cars. You might not expect an EV charger to share that stage, but among the 2019 Red Dot… Read more »
Tritium’s 350 kW DC charger introduced in Australia
EV charging equipment manufacturer Tritium has introduced its Veefil-PK 350 kW DC charger to Australia. Two Veefil-PK chargers are installed at the Toombul Shopping Center in Brisbane, operated by charging network provider Chargefox. The Veefil-PK can charge two EVs simultaneously and is equipped with CCS2 plug types. According to Tritium, the charger can add up… Read more »
A closer look at the losses in power semiconductors
A previous article examined loss mechanisms in traction motors, which tend to be the single biggest source of losses in a modern EV drivetrain. This time, the focus is on the various power semiconductors, as they are the next biggest source of losses. Also covered in brief are ways to mitigate these losses and design… Read more »
SAE updates J2954 wireless charging standards for EVs up to 11 kW
SAE International has published a second version of Recommended Practice (RP) SAE J2954, its standard for wireless power transfer (WPT) for EVs of up to 11 kW power levels. The RP establishes specifications for interoperability, electromagnetic compatibility, EMF, minimum performance, safety, and testing for wireless charging of light-duty electric and plug-in EVs. SAE is seeking… Read more »
