Latest Patents

Giraud holds a patent for a system and method of estimating the state of charge of a battery using coulomb counting estimation with periodic calibration through artificial intelligence. This battery management system is designed to track the state of charge of a battery that includes multiple cells. The system features a coulomb counter (CC) estimator that determines the charge difference over time, allowing for precise tracking of each cell's state of charge. Additionally, an artificial intelligence (AI) estimator converts a set of sample values from a cell into an estimated state of charge for calibration purposes. The controller periodically invokes the AI estimator to ensure accurate calibration and updates the corresponding state of charge values. The AI-based calibration utilizes Long Short-Term Memories and incorporates voltage mean and variance over time, optimizing the processing required for accurate estimations.
