In a key move for hydrogen-powered electric technology, Bosch is starting volume production of fuel cell systems for electric vehicles using technology from Powercell (writes Nick Flaherty).

The two companies will jointly develop polymer-electrolyte membrane stacks for fuel cells that convert hydrogen to electricity, and Bosch will make the stacks under licence in 2022. Bosch, a...

Axial flux motors have many EV design advantages over their radial flux counterparts, as Nick Flaherty explains. A new type of motor is gaining traction in the e-mobility sector – the axial flux type. For many years they have been used in stationary applications such as elevators and agricultural machinery, but over the past decade a number of developers have been working on improving...

Mack Trucks has launched a batteryelectric vehicle (BEV) waste compactor as a demonstrator and will begin real-world testing in 2020 in New York (writes Nick Flaherty).

Refuse trucks are a major challenge for electrification, as they have to make multiple stops, often up to 1000 times on a route, and the motors have to provide high torque at...

Peter Donaldson reports on the design and development of this bulk material mover, the first in its class to become commercially available.

In construction and mining, wheel loaders move material in bulk, often scooping it from piles with a bucket and then lifting and dumping it into a truck or crusher. Most are powered by diesel engines coupled to...

The world’s first five-seat, battery powered electric aircraft has taken its maiden flight (writes Nick Flaherty).

A full-scale, full-weight prototype developed by Lilium, in Munich, Germany, has 36 all-electric ducted fan engines that allow it to take off and land vertically, and transition to and from horizontal flight. It has two fixed wings, one main wing at the...

Powertrain manufacturer TM4 has developed a compact bidirectional charger that provides battery charging functionality as well as auxiliary power supply during vehicle operation – using the same power electronic modules to supply a configurable voltage and frequency output to auxiliary devices (writes Lawrence Butcher).

In charger mode, the TM4 BCI20 converts AC to DC to charge the electric vehicle’s battery. When a vehicle is in use, the unit becomes a...

There is something of an ongoing debate in the world of e-mobility as to hydrogen’s place in the energy ecosystem (writes Lawrence Butcher).

While manufacturers such as Toyota are throwing their weight behind the fuel, and actively marketing fuel cell electric vehicles (FCEVs), others such as...

The Automobile Association of America (AAA) has conducted primary research into understanding the effects of ambient temperatures on the range and equivalent fuel economy of five battery electric vehicles (writes Nick Flaherty).

Testing was carried out at 20 F (-7 C), 75 F (24 C) and 95 F (35 C). For these temperatures, the effect of various HVAC systems on the battery range and equivalent fuel economy was...

Paraclete Energy, which makes high capacity, surface-modified silicon nanoparticles for use in battery applications, recently released its SMSilicon/3590, the highest capacity, cycle-stable, validated anode material yet brought to market.

It is aimed at anode material companies as a graphite precursor, and lithium-ion battery manufacturers who want to...

Rory Jackson explains how various test methods work, why they are important and how EV developers can set up their own facilities.

Throughout the course of electric and hybrid vehicle development, it is important to remember that the overall system consists of a number of different parts, each in need of...
