Model for predicting battery RUL

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.

New battery design for longer-range EVs

Researchers in the UK have developed a battery design that could significantly extend the range of EVs, writes Nick Flaherty. A team at the University of Surrey’s Advanced Technology Institute (ATI) has developed a technique for making silicon-coated carbon nanotubes (CNTs) that can be used for high-volume roll-to-roll production of anodes for lithium-ion batteries. The […]

Flyback converter for e-bike chargers

Power Integrations (PI) has updated a key power converter for higher-power e-bike chargers with a new control algorithm and more power-efficient gallium nitride (GaN), writes Nick Flaherty. TOPSwitch is a simple single flyback converter that is used around the globe. The latest version with GaN extends the flyback converter from 250 up to 450 W for the higher-power battery chargers in e-bikes.
