Ystral Batt-TDS offers faster electrode slurry mixing
Surging EV adoption has placed unprecedented demand on lithium-ion battery production, so advances in manufacturing processes such as electrode slurry production are critical. Read more…
Isolation technologies
Nick Flaherty investigates techniques
that enable digital controllers to interface safely with high-voltage systems.
As automotive designs move to electrification, high-power electronics have become critical components in new electronic drivetrain and battery systems. Communication and control from low-voltage digital devices requires electrical isolation of the high-voltage elements from the low-voltage side, covered by the extra-low voltage (SELV) regulations.

Dynisma DMG family
Seamless simulation Peter Donaldson checks out simulators designed to give drivers the most realistic response and feel Dynisma’s DMG family of simulators is designed to reduce the time and expense involved in building and testing vehicles by moving as much prototype development as possible into the virtual world. We caught up with the company’s commercial director, […] Read more…
The Battery Show USA show report
A wealth of advanced battery tech for EVs was on show in Detroit, as Peter Donaldson reports.
Staged for the first time at Huntington Place, Detroit, The Battery Show and Electric & Hybrid Vehicle Technology Expo, North America showcased a myriad advanced battery technologies. Organiser Informa Markets reports that more than 21,000 professionals from around the world attended and 1250 organisations exhibited, making the 2024 event the largest in its history, which dates back to 2010.

Battery cell manufacturing
There are three major phases of activity for manufacturing battery cells, as Nick Flaherty reports
Moving from small coin cells that prove the performance of a battery chemistry in the laboratory to production is a big step. There are many different ways to construct a cell, and many techniques for both building and characterising the resulting battery. Read more…
Evice Rolls-Royce Corniche
Evice is using modern technologies and EV powertrains to improve some of the best cars ever built, starting with a beautiful Rolls-Royce Corniche, reports Will Gray.
When it comes to pure, opulent luxury, there are few more iconic cars than those produced by Rolls-Royce in the 1970s and 80s. Read more…
In conversation: John Stamford
The advanced powertrain chief engineer of Jaguar Land Rover got into EVs before EVs were even a thing. He tells Will Gray how far things have come
If you want to understand the evolution of electric vehicles (EVs), there are few better to speak to than Jaguar Land Rover’s advanced powertrain chief engineer, John Stamford. Read more…
Multi-chemistry batteries
alt=’E-Mobility Engineering’>
A little over a year ago, a BMW iX electric SUV fitted experimentally with a dual-chemistry Gemini battery pack from Our Next Energy (ONE) drove 978 km (608 miles) on a single charge – an impressive achievement for such a large, heavy car, writes Peter Donaldson. Read more…
Hercules to be the biggest electrified aircraft
Wright Electric is developing the powertrain for a hybrid version of the C-130 transport aircraft, the Hercules, writes Nick Flaherty.
It would use two conventional turbines and two electric propulsors, with the batteries held in the cargo area, making it the largest aircraft to be electrified.
The project would use the second-generation, MW-class motor, the WM2500, built with support from the US ARPA-E programme and NASA space agency, which is nearly complete. Read more…

Making powertrains faster with the aid of AI
Monumo has used two forms of artificial intelligence (AI)
to speed the development of powertrain systems for e-mobility, writes Nick Flaherty.
Time pressures often limit collaboration between sub-system teams in the early stages of design, which means genuine system-level optimisation is limited, said Simon Shepherd, head of hardware development at Monumo. Read more…
