Fibre Battery can be Woven and Washed

This submarine drone is powered by a 20-meter-long fiber battery that is wrapped on its surface.

For me, one of the most interesting areas of the industry is flexible electronics. Traditional devices are designed onto a circuit board and enclosed in a box. The advent of the Internet of Things has meant that electronic designs have to be integrated into all sorts of places, some of which have no room for any si

The Correct Route Extends EV Range

Balázs Kulcsár, Professor at the Department of Electrical Engineering at Chalmers University of Technology

One of the main stumbling blocks to electric vehicle adoption is range anxiety. Until now most of the focus on extending range was on the vehicle itself and the battery that holds the electric charge. There is no doubt that making the vehicle lighter, the electric drivetrain more efficient and the battery hold m

Figure 1: EV charging systems are migrating rapidly in the direction of DC-based 50kW to 350kW power solutions

Now that the latest Electric Vehicles (EVs) are exhibiting operational ranges satisfactory to the general public, the attention has shifted to battery charging times. These EVs are using the latest in wide-bandgap semiconductor solutions and power topologies, with system voltages often well over several hundred vo

Figure 1. Modern bus depot with charging infrastructure

With the electrification of heavy-duty or commercial vehicles, charging larger batteries than the ones in electric passenger cars becomes necessary. As time is money especially in logistics, either assigning idle times for charging or increasing charging power are preferred options. This leads to three different ch

Transportation and Electrification
It has been a challenging and often frustrating year for us all and hopefully next year will give us a fresh start, or at least put us on the path to one. The chip shortage has persisted longer than most analysts thought and it may now be the middle of next year before the fabs have caught up with demand. The sh

Transporting You Into the New Year
We stand on the precipice of one of the greatest gauntlets all year (and into the next) with two intertwined topics for December and January – “Transportation” and “EV + Charging Infrastructure + Hybrid Vehicles,” respectively. But before we dive into this month’s focus, I wanted to personally thank ou
