Adden Energy will work to scale the battery up to a palm-sized pouch cell, and then upward toward a full-scale vehicle battery in the next three to five years

Solid-State Batteries Coming Closer to Commercialization

Ally Winning, European Editor, PSD

Solid-state batteries offer all the upsides of the Li-ion batteries that electric vehicles use, but have much fewer downsides. The time it takes them to charge can be measured in minutes, rather than hours, and because they don’t have a liquid electrolyte, they are much safer and far less prone to bursting in

Independent Testing Helps Solve Battery Temperature Issues

Bernard Ang, Brian Whitaker, Keysight Technologies

Large-scale applications typically use battery packs with modules wired in series and parallel connections. Thermal sensors placed strategically across a battery pack detect temperature variations. Large battery-pack thermal imbalance usually starts with the non-uniformities of battery cells affecting their charging and

Pushing EVs Ahead of the Curve

Jianwen Shao, Discrete Applications Manager, WolfSpeed

Electric vehicle (EV) on-board chargers (OBCs) can take several forms based on power level and functions. Charging powers vary from less than 2 kW in applications such as electric scooters to 22 kW in high-end EVs. Traditionally, charging power is unidirectional, but bi-directional charging is gaining traction. Why bidirectional OBC
