Have We Reached the Age of the Solid-State Battery?

Ally Winning, European Editor, PSD

For a long time we have known that the solid-state battery would be the next big step in battery technology. While scientists and researchers have spent many years trying to develop other battery chemistries, the solid-state battery is more likely to bring almost immediate improvements to our energy storage. The other

An Engineer's Guide to EV Battery Management Systems

Mark Patrick, Mouser Electronics

An EV's primary energy source is a battery pack (Figure 1). A pack is typically designed to fit on the vehicle's underside, between the front and back wheels, and occupies the space usually reserved for a transmission tunnel, exhaust, and fuel tank in an internal combustion vehicle. Keeping the pack as low as poss
