Eatron and University of Warwick develop new EV battery health algorithms
Software company Eatron and Warwick Manufacturing Group at the University of Warwick, UK, have developed a new approach to evaluating an EV battery’s remaining useful life (RUL). The VIPER (Validated & Integrated Platform for battery Remaining Useful Life) project, funded by the Faraday Institution, uses WMG’s electrochemical models and Eatron’s cloud battery management and integration… Read more »
DuPont’s new glycol-purification solution can extend the lifetime of EV coolants
Chemical giant DuPont has launched a new glycol-purification solution for e-mobility. DuPont AmberLite EV2X resin is designed to extend the lifetime of EV coolants while reducing glycol maintenance requirements. Unlike ICE vehicles, EVs have to manage conductivity within their systems. The degradation of the glycol coolant and other components within the thermal management system releases… Read more »
Battery cell qualification for EVs: Lucid’s cell specialist discusses the complicated process
Q&A with Lucid’s Battery Cell Technical Specialist Maithri Venkat. When it comes to battery cells for EVs, one size definitely doesn’t fit all. The properties of a particular cell act as constraining factors for every aspect of a vehicle’s design—and not only for vehicle performance parameters such as range and power, but for the development… Read more »

How to Improve Battery Cell Quality
As the demand for batteries in electric vehicles and renewable energy storage systems continues to grow, manufacturers face the challenge of producing high-quality battery cells at large scale while minimizing defects and maximizing throughput. To achieve this, it’s crucial to implement effective testing and inspection techniques throughout the manufacturing process. This session will discuss novel… Read more »
How to improve EV traction motor efficiency
A look at improving motor efficiency in two main categories: electrical and mechanical. Regular readers of Charged don’t need to be told that the typical EV drivetrain is way more efficient from battery to wheels than its ICE-based equivalent, but it is perhaps less well-known that the approximate drivetrain efficiency ranges from 75-90% for the… Read more »
NOVONIX and SandboxAQ collaborate on system to predict EV battery lifespan
Battery materials firm NOVONIX and enterprise SaaS provider SandboxAQ will collaborate to predict the lifespan of lithium-ion batteries, using SandboxAQ’s AI-driven chemical simulation software and NOVONIX’s Ultra-High Precision Coulometry (UHPC) technology and battery cell prototyping and testing capabilities. The companies expect to use the resulting models for data products and services in the first half… Read more »
