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

Topology Selection For Bidirectional Energy Flow Applications Using WBG Devices


The paper provides an overview of the topology for bidirectional converters and discusses their different usage. Bidirectional energy flow applications are usually found in energy storage systems, battery systems, and can be categorized as grid-connected and DC-DC-connected. In grid-connected applications, two power conversion stages, which are power factor corrector (PFC) rectifier/inverter an... » read more
