Title: The Innovations of Robert W. Chalfant
Introduction
Robert W. Chalfant is a notable inventor based in Farmington, NY (US), recognized for his contributions to battery management systems. With a total of 9 patents to his name, Chalfant has made significant strides in the field of distributed feedback control systems.
Latest Patents
Chalfant's latest patents include advancements in distributed feedback control systems and logic for battery management system (BMS) operation. These innovations present feedback control systems designed for monitoring battery system hardware. The methods outlined for operating such systems involve vehicles equipped with wireless battery management systems (WBMS) governed through distributed feedback control. A key aspect of his work includes a method where a wireless-enabled manager device selects a batch of cell module assemblies (CMA) within the WBMS to communicate with, thereby retrieving data for their respective battery modules. The process involves creating a manager access control list (ACL) with respective media access control (MAC) addresses and ID data for the selected CMAs. A wireless connection is then established between the manager device and each selected cell monitoring unit (CMU) based on the corresponding MAC addresses and ID data in the manager ACL. The manager device downloads device data for each battery module associated with the selected CMA and subsequently switches the operating mode for each CMU.
Another significant patent focuses on a system for evaluating battery connection quality in one or more battery modules of a battery assembly. This system includes a battery testing unit with a housing that features a plurality of testing modules. These modules communicate with and electrically contact the battery modules of the assembly. Each testing module is equipped with connectors and contacts to evaluate voltage and resistance measurements simultaneously.
