Latest Patents
Ben Johnson holds a patent for "Methods and apparatus for contactor weld detection in a vehicle." This patent introduces a mechanism for weld detection that utilizes isolation monitoring circuits. These circuits measure the leakage current between the battery's positive and negative terminals to the chassis ground. The mechanism checks the health status of the contactors by connecting the isolation monitoring circuit between two points on the battery pack. It measures the resistance of these points, ensuring the continuity of the contactors in the system. This technology is crucial as it can identify whether a contactor is completely welded or partially welded. In cases of partial welds, the vehicle can rectify the issue by activating and deactivating the contactors multiple times, with or without high current. The proposed mechanism leverages existing measurement circuits designed for high reliability, which is essential for electric vehicles. This innovation not only enhances safety but also reduces the overall cost of the vehicle.
