Next-Gen Batteries Require Impedance Data And Active Balancing


Key Takeaways Electric vehicles and energy storage systems using LFP batteries require more sophisticated diagnostic methods because they exhibit very flat cell voltages across various charge levels, making it harder to estimate usable energy. Battery management systems are leveraging new components, AI/ML, digital twins, and other techniques to get more accurate, real-time data, includ... » read more

Batteries Charge To The Edge


Long-awaited advances in battery chemistry and materials science are beginning to roll out, opening the door for higher capacity, faster charging, and much lower likelihood of thermal runaway. This is a high-stakes race, fueled by an insatiable demand for power everywhere from handheld devices to data centers. When Finland's Donut Lab claimed earlier this year that it had developed a solid-s... » read more

Moving Electrons, Not Just Vehicles


Key Takeaways: There are several ways to convert AC power from the grid to DC power in the system. Some degrade the battery faster than others. Battery management systems monitor cell voltage, current, and temperature, helping to estimate state of charge, health, and useful remaining life. A PMIC with a multi-level converter is the most efficient way to get power from the battery to ... » read more

HW Security: Pager, Walkie-talkie And Other Battery-Power System Attacks (U. of Florida)


A new technical paper titled "When Everyday Devices Become Weapons: A Closer Look at the Pager and Walkie-talkie Attacks" was published by researchers at University of Florida. Abstract "Battery-powered technologies like pagers and walkie-talkies have long been integral to civilian and military operations. However, the potential for such everyday devices to be weaponized has largely been un... » read more
