E-Mobility Engineering

A worker checks one of Kempower’s modular high-power chargers, which are based on 50 kW power blocks (Image: Kempower) As the fundamental electronics of EV fast chargers mature, Peter Donaldson considers the options available to manufacturers for upscaling production EV charging has reached an inflection point as an industry. The fundamental power electronics of fast charging are largely mature.

The giant Liebherr LRH200 in operation on a site in Stockholm (Image: Clemens Niederée) Piling is – quite literally – the foundation of construction and while the machines that do it barely move, electrifying their operation is essential for net zero. Will Gray reports The quest for net zero will only ever be achieved if the world develops ways to decarbonise construction, and heavy-duty on-site machinery is one of the major elements in that industry.

The CNN-GRU-PF fusion model for battery lifetime (Image: Chang’an University) A new way to model the lifetime of batteries has been developed by researchers in China, writes Nick Flaherty. Accurate prediction of the remaining useful life (RUL) of a battery – as in the number of cycles left before this failure point – is essential for proactive battery management, preventing unexpected failures, optimising replacement schedules, and reducing costs and safety risks in real-world applications.

The SAM9X75D5M System-in-Package for EV digital displays and chargers (Image: Microchip) Microchip has developed a System-in-Package (SiP) that simplifies the development of automotive displays, writes Nick Flaherty. The SAM9X75D5M SiP is AEC-Q100 Grade 2-qualified and supports large display sizes up to 10 in and XGA resolution of 1024 x 768 pixels.

Parker’s CoolTherm thermal interface material applied directly to cylindrical lithium-ion battery cells, eliminating the need for a traditional cooling plate in EV battery pack assemblies (Image credit: Parker Lord) Parker Hannifin has introduced a new silicone foam material aimed at improving battery safety in cylindrical lithium-ion cell packs.

The MG4 EV Urban is the launch platform for the company’s lithium-manganese-oxide-based SolidCore semi-solid battery technology (Image: MG) As EVs migrate to higher voltages and more aggressive operating environments, the demand for protective coatings has shifted from passive defence to active engineering.

Coatings used to protect public chargers must resist environmental stressors such as UV radiation, salt spray, and industrial pollutants over long periods (Image: AkzoNobel) As EVs migrate to higher voltages and more aggressive operating environments, the demand for protective coatings has shifted from passive defence to active engineering.

Battery debonding (Image: Henkel) Henkel’s debonding-on-demand technology turns EV batteries from “single-use” assets into repairable, upgradeable and recyclable platforms, cutting costs across the full lifecycle while helping OEMs meet circularity and regulatory targets. The solution combines robust in-use bonding with controlled, precise separation on-demand, allowing valuable materials to remain in circulation across multiple lifecycles and supporting a more sustainable EV battery ecosystem.

FLASH Charging infrastructure design emphasises user ergonomics to handle heavy cables and local energy storage to minimise grid impact. (Image: BYD) Behind the recent headlines surrounding BYD’s “flash charging” technology is an intriguing case study in holistic system integration.

In battery module and pack assembly, LORD 5206 acrylic adhesive with 55GB accelerator bonds well to aluminium and most steel coatings. (Image: Parker LORD Making the EV battery pack a structural component of the vehicle has placed unprecedented demands on joining technologies. As engineers strive to increase energy density, manage thermal loads, and ensure crashworthiness, the limitations of traditional welding and mechanical fasteners become increasingly apparent, writes Peter Donaldson.
