Modular plug-and-play rectifier

OmniOn Power has developed a modular 30 kW rectifier in a 19 in rack format to build EV fast chargers (writes Nick Flaherty). The EV100H3NK and EV101H3N1K AC-DC variants of the rectifier design have efficiencies of up to 96% and integrate CAN automotive comms protocols. Up to 12 rectifiers can be used in parallel in a 19 in rack to build fast-charging 360 kW systems quickly and easily.

Mini-spoiler alert for faster flight

Researchers at the University of Bath are investigating how deploying spoiler-like devices called mini-tabs could help electric aircraft fly faster (writes Nick Flaherty). Mini-tabs can counteract the damaging vibrations caused by whirl flutter that occurs at high flight speeds. Maxon has provided the motion systems to test

Refuelling pump seals the FC deal

Researchers in the US have developed a sealed compressor using a linear motor for refuelling hydrogen EVs (writes Nick Flaherty). The hydrogen compressor, developed at the Southwest Research Institute (SwRI), can improve the efficiency and reliability of hydrogen compression used in the refuelling of fuel cell EVs (FCEVs).

Detectors do more using less

Nisshinbo Micro Devices has launched two voltage detectors that are designed to provide higher accuracy in ECUs and BMSs using fewer components (writes Nick Flaherty). When monitoring high voltages, it is crucial to consider the drawbacks of using traditional low-voltage detectors with an open drain output. The NV3600 and...

Solar PV system powers electric boats in Gambian village

A start-up is working in Africa to electrify fishing boats (writes Nick Flaherty). VoltaViewAfrica was set up by a professor from the Fraunhofer research institute in Germany. Photovoltaics generate electricity, which is stored in mobile, portable lithium batteries that local residents can use as an individual power source which includes powering local fishing boats.

Solar supplement for hybrid truck

Scania has shown a prototype of an electric truck that uses solar panels to provide additional power for propulsion (writes Nick Flaherty). The truck is a regular 100 kWh Scania plug-in hybrid connected to a trailer with 200 kWh of additional batteries as a power bank. These are connected to the solar panels. “When we first

Graphene-free liquid cooling

Researchers at Samsung have developed a design for a liquid-cooled thermal management system (TMS) for large lithium-ion battery packs (writes Nick Flaherty). They first built a coupled 3D electrochemical/thermal model of a battery pack that avoids the use of materials such as graphene. Simulation showed that
