Fleets and Infrastructure Features

EuroGroup’s new gluing technology promises to improve motor efficiency and reshape electric machine design

Groundbreaking glue: New results show as much as 44% core loss reductions for the same steel and lamination thickness. Many design decisions in the EV industry are still driven by range. Engineers remain focused on delivering system efficiency improvements, because it directly translates into delivering more range without increasing the size and cost of the… Read more »

A closer look at advances in power PCBs

In just the last few years there have been some major improvements in printed circuit board technology that are especially relevant to power electronics. Arguably the most important of the recent advances is the development of new board substrates that can withstand higher temperatures, along with metal cores for improved heat transfer, and the ability… Read more »

Cable sizing and selection for EV systems

Why Champlain Cable backs irradiation cross-linking for high-voltage EV cable insulation When you think of what makes up an EV, cables and wires probably aren’t the first components that come to mind. But these conduits comprise the electrical cardiovascular system that makes a vehicle function – from the battery to the motor and all the… Read more »

AC Fast Charging: The right fit for medium-duty EVs

What’s the largest mass transit system in the United States? Is it the public transit network? Nope. Commercial airlines? Guess again. Passenger rail? Not even close. Here’s a hint: the vehicles are colored yellow. Give up? It’s school buses, and in terms of sheer numbers this fleet is 2.5 times larger than all other forms… Read more »

V2G value propositions: Fermata Energy is focused on building financially viable solutions for vehicle-to-grid

David Slutzky, an accomplished entrepreneur, has an eclectic background. In addition to having founded several successful companies, he’s served as a local elected official as well as a Senior Policy Advisor in the Clinton White House and the EPA. He’s been teaching at the University of Virginia for some time, on the Commerce, Architecture and… Read more »

A closer look at current sensors in EVs

Pretty much every electronic circuit that handles significant power utilizes some means of measuring current, whether to simply protect against overload or because it is a basic functional requirement. In this article we’ll cover some of the more common devices and circuit techniques for measuring current in the major subsystems of an EV, including when… Read more »

Sparkcharge launches a portable and scalable DC fast charging unit

The all-electric transport system of the future is a work in progress, to say the least. In fact, at the moment we stand near the beginning of the transition, and many aspects of the charged world to come are not yet clear. It may be that the EV ecosystem that we now foresee will prove… Read more »

Pre-Switch promises to add 5-12% more EV range by eliminating switching losses

How would you like it if your EV could go ten percent farther with the same size battery? You’d love it, of course, and so would every EV manufacturer out there. Range is one of the most important parameters in the EV industry, as many potential EV drivers are apprehensive about lower range ratings. Manufacturers… Read more »

Easelink wants to set a new standard for EV charging: Automatic and conductive

On average, you park your EV once every nine miles. Imagine if every one of those times, your car could quickly recharge without any intervention on your part. This is the vision of Easelink, an EV charging company based in Graz, Austria. Easelink wants to put its Matrix Charging technology in parking spots far and… Read more »

Mobile EV chargers deliver power where it’s needed

A few companies have introduced mobile charging products to solve unique challenges. The perceived lack of ready access to charging stations is one factor that has limited consumers’ interest in buying electric vehicles. While the number and diversity of locations of EV charging stations are growing, thanks to networks such as Electrify America, chargers can… Read more »
