Scalvy, a company developing distributed power delivery systems, has completed a concept evaluation of its battery-integrated architecture within an automotive system developed in collaboration with Valeo.
The approach replaces centralized power conversion components, such as inverters, dc-dc converters, and onboard chargers, with distributed modules referred to as “Power Neurons.”
These modules are integrated at the battery level and manage power conversion locally, enabling a modular architecture that can scale across different electric vehicle platforms and battery configurations.
The evaluation was conducted under laboratory conditions using the Worldwide Harmonized Light Vehicle Test Cycle (WLTC) to assess system behavior under representative driving conditions.
Results indicated improved state-of-charge (SoC) balancing across battery modules, with minimal deviation observed during operation. The architecture also demonstrated reduced electrical and thermal stress due to distributed switching behavior, which may contribute to slower battery degradation and extended lifecycle performance.
The system achieved a peak inverter efficiency of 98.3% under test conditions, with stable thermal performance observed across motor and power devices.
The evaluation also confirmed integration of inverter, onboard charger, and dc-dc conversion functions within the distributed architecture. The technology is currently undergoing further testing, with sample deployments expected ahead of potential commercialization.
