Adhesives: essential EV enablers


Adhesives are used in vehicles of all kinds, but they are particularly essential in electric vehicles (EVs) because they perform key functions within battery packs and help save weight in body structure, translating into performance and energy efficiency, as David Fetterman, PPG Industries’ global segment director for adhesives and sealants, explains to Peter Donaldson.

Tata Passenger Electric Mobility launches its first Pure EV architecture – ‘acti.ev’


Tata Passenger Electric Mobility (TPEM), have introduced its first advanced Pure EV architecture – acti.ev (pronounced as active). acti.ev stands for (Advanced Connected Tech-Intelligent Electric Vehicle).
The acti.ev architecture is based on the key pillars of Performance, Technology, Modularity, and Space Efficiency and consists of four layers: Read more…

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. Read more…

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 the effectiveness of the mini-tabs on a novel wind tunnel test rig. Read more…

Improving power electronics


Nick Flaherty reports on how semiconductor r&d is leading to more efficient and powerful electronic switching solutions for e-mobility
Power devices for e-mobility come in a range of technologies to boost performance and efficiency. Insulated gate bipolar transistors (IGBTs) made from silicon have been the original power switch for decades; they are robust and low cost but can only switch at frequencies of around… Read more…

Extinguishing lithium battery fires


Our battery show report in this issue contains stories on various materials engineered to prevent a thermal runaway in a cell in a lithium-ion pack from spreading and cause a major fire (writes Peter Donaldson).
Prevention is better than cure because, rare though they are, thermal runaways in EV lithium-ion batteries contain all four elements of the ‘fire tetrahedron’ – heat, oxygen, fuel and a chemical reaction – making them notoriously hard to extinguish. Putting them out is far from impossible, however. Read more…
