Only one year after they were first introduced, Cree’s Wolfspeed Technologies has announced its third generation of 1,200 V SiC MOSFETs. Designed for EV powertrain applications, Wolfspeed claims that the MOSFET has the highest figure of merit on the market today, with low drain-source on resistance (RDS) performance and the industry’s lowest switching losses. Samples are currently available… Read more »

Fastned opens its first DC fast charging station in Germany
European fast charging network operator Fastned has opened its first station in Germany. The new station is located along the A3 highway at Limburg an der Lahn, and features several 350 kW DC chargers. The roof of the station is equipped with solar panels. According to Fastned, all the energy delivered by its network comes… Read more »
Infineon introduces new CoolSic Schottky diodes for on-board charger applications
Infineon Technologies’ new CoolSiC diodes are designed for ruggedness and efficiency, to meet the high standards required of hybrid and electric vehicles. Infineon says these diodes are the most durable on the market, due to their high corrosion and humidity resistance. The company will release CoolSiC Diodes in the 650 V class in September. An… Read more »
Super B and Lithium Werks forge supply agreement to meet growing battery demand
Lithium Werks, a producer of Li-ion phosphate energy cells, and Super B, a specialist in lithium battery solutions, have agreed to work together to increase their overall battery production. The agreement calls for an expansion of Super B’s operations, including solutions for transportation and renewable energy needs, and a ramping-up of Lithium Werks’ nanophosphate cell… Read more »
How to protect circuits in battery management systems
Sponsored by Littelfuse By Carlos Castro, Global Director Marketing Automotive Electronics, Littelfuse, Inc. As hybrid and electric vehicles roll closer to battery power drive systems with 48V or higher, the lithium-ion battery in a closed system is the clear leader for power. Lithium-ion gets high marks in cost, energy efficiency, temperature performance, power-to-weight ratio and lifecycle…. Read more »
Argonne reviews 40 EV market analyses from 16 countries
A team of researchers at the DOE’s Argonne National Laboratory has conducted a review of 40 automotive market studies from 16 countries, including the US, Germany, China, South Korea, the UK and Ireland. These studies modeled the decision factors that drive consumers to buy plug-in vehicles (PEVs). The study addressed such issues as: projected market… Read more »
Robert Bollinger is building unique EVs, and a one-of-a-kind EV company
Bollinger Motors is not following the typical EV startup formula. Instead of building a luxury sedan, it’s building a rough and ready work truck. It has no strategy to evolve into a mass-market automaker, but intends to find a niche as a low-volume brand. As far as we know, the company has no former Tesla… Read more »
A closer look at film capacitors
Plastic film capacitors relentlessly continue to take over many of the duties in EV power electronics that were once performed by the venerable aluminum electrolytic type, mainly because film capacitors exhibit much lower losses and have a much longer operational lifespan, especially at ambient temperatures in the 75-85° C range. The tradeoff is that film… Read more »
Tecnomatic helps automakers design specialty assembly processes for advanced stator technologies
There seems to be an endless array of electric motor topologies, architectures, and configurations. Among the many design choices that engineers face is the shape of copper wire that is wound in the stator. In a new paper published in the IEEE Transactions on Industry Applications, researchers compared using flat wire hairpin winding and stranded… Read more »
