In 2018, Swiss rail vehicle manufacturer Stadler began a research project to develop a battery-powered train designed to operate on non-electrified or semi-electrified lines. Now the Flirt Akku (akku is the German term for a battery), which carries its batteries on the roof, has covered some 15,000 km in pure battery operation, and has demonstrated… Read more »

Vancouver public buses to use BAE Systems Series-EV electric propulsion systems
Fifteen public buses in Vancouver, Canada, will be fitted with BAE Systems’ Series-EV electric propulsion system. Series-EV integrates electric motors, controls and batteries. The latest version of the system uses fewer, lighter, and more compact components compared to the previous generation. It’s designed to be easy to install and extremely efficient. UK-based BAE Systems has… Read more »
Is aviation the best application yet for hydrogen fuel cells?
Q&A with ZeroAvia CEO Passenger cars are well on their way to going electric, and the path to a big market share for heavy-duty EVs such as buses and delivery trucks is becoming clearer. However, aviation remains a new frontier for zero emissions. There are several new powertrain options, and none has yet proven itself… Read more »
Elon Musk and Sandy Munro talk Production Hell, megacastings, structural battery packs and much more
This is a meeting that promises to be fascinating for any EV fan—Elon Musk speaks to auto manufacturing expert Sandy Munro for over 45 minutes. Sandy has become something of an internet star of late for his insightful comments (both positive and negative) about Teslas and other EVs. In this new video on the Munro… Read more »
Isolation technologies for EV power electronics
A previous article on bidirectional chargers touched on using transformers to provide isolation at high power levels—in which application they are the only game in town, really—but this time the focus will be on achieving isolation at low power levels, such as the feedback signal in a regulator, data communication buses between devices, gate drivers… Read more »
