Headless load management coordinates EV chargers across multiple backend platforms
FLEXECHARGE is deploying its HARMON-E load-management technology across 1,000 Circle K electric vehicle (EV) charge points using a headless architecture that integrates directly with the operator’s existing energy-management systems. Rather than introducing an additional operational interface, FLEXECHARGE delivers the load-management functionality and data into Circle K’s existing systems and dashboards through APIs. The approach allows…
Vibration-aware model improves EV battery state-of-charge estimation
Researchers at California State University, Fresno and Chungnam National University have developed a state of charge (SoC) estimation method that accounts for battery capacity degradation caused by mechanical vibration in electric vehicles (EVs). Conventional SoC estimation methods commonly combine equivalent circuit models (ECMs) with an extended Kalman filter (EKF). However, these models generally don’t account…
Princeton NuEnergy and SK Battery America expand closed-loop battery recycling
Princeton NuEnergy (PNE) and SK Battery America (SKBA) are expanding their collaboration to develop a closed-loop recycling pathway for battery manufacturing scrap generated at SKBA’s electric vehicle (EV) battery facilities in Commerce, Georgia. Under the planned collaboration, PNE will receive battery manufacturing scrap from SKBA. The companies are also exploring the development of a recycling…
Thermoplastics achieve 900-V UL rating for high-voltage applications
Two engineering thermoplastics from NexPoint Materials, LEXAN BPL1000 and CYCOLOY C2950 resins, have achieved the highest rating in the UL 2597 Surface Tracking Test (STT) for high-voltage applications at 900 V. The results provide performance data for engineers evaluating insulating materials for high-voltage applications, including electric vehicle (EV) systems, faster-charging architectures, connectors, and battery systems.…
IONNA expands 400-kW EV charging network to more than 180 sites
IONNA has expanded its US electric vehicle (EV) charging network to more than 180 active sites, more than doubling its footprint since the beginning of 2026. The company says it is now the largest 400-kW charging network in the US. More than 40 of those locations are Rechargeries at Circle K stores, following a partnership…

How does fault-tolerant control keep an EV operating after a sensor failure?
The rotor in an electric vehicle (EV) traction motor delivers torque through the motor shaft to the drivetrain. A rotor-position sensor, such as a resolver, reports the rotor angle needed for accurate torque control. If the sensor fails, fault-tolerant firmware can substitute a model-based estimate. This article reviews how the inverter controller detects a failed…
