Latest Patents
One of his latest patents is titled "Determination and utilization of over-predictive battery state of charge." This patent describes a battery system that includes a multi-cell rechargeable energy storage system (RESS) and an electronic controller. The controller processes RESS cell data and is programmed with a battery cell open circuit voltage (OCV) versus state of charge (SOC) data table. It calculates a peak OCV movement for a representative battery cell at predetermined capacity and maximum discharge/charge rate. The controller acquires voltage data during active RESS cycling and uses a first-order lag filter algorithm to generate an overpredicted OCV for the subject cell. Additionally, it determines an overpredicted SOC value for the subject cell and regulates the RESS accordingly.
Another significant patent by Bednar is the "Method and system for battery capacity estimation using voltage slope capacity and dynamic anchors." This method involves monitoring a sensor and collecting data points, including a voltage-based state of charge value and an integrated current value. It defines two data sets collected during different time periods and determines an integrated current error related to the second data set. If the error exceeds a threshold, the method resets the second data set based on an integrated current value from the first time period. The data sets are then combined to create a combined data set, allowing for a voltage slope capacity estimate.
