Title: Innovations by Jeffrey A. Rose

Introduction

Jeffrey A. Rose is an accomplished inventor based in La Jolla, California. He has made significant contributions to the field of electrical engineering, particularly in the area of battery charging systems and capacitive coupling technologies. With a total of 3 patents to his name, his work reflects a commitment to advancing technology in practical and efficient ways.

Latest Patents

One of his latest patents is focused on capacitive charge coupling with dual connector assemblies and charging. This invention provides a disengageable electrical capacitive coupling for transmitting high-frequency AC electrical current. In an electric vehicle charging system, dual first connectors form the vehicle inlet, while mating dual second connectors form the coupler. A dielectric material, such as barium titanium oxide, is positioned between the connectors to form capacitors. The design allows for a highly efficient, compact electrostatic field for transmitting current, with provisions for easily disengaging the connectors once the charging cycle is complete.

Another notable patent is a battery charging method with a stepped current profile. This method includes a DC charge current supply with a variable output, allowing the charging current to be varied based on several sensed parameters in the circuit. The process involves applying a constant charging current initially, followed by a series of incremental step reductions in charging current as the battery voltage approaches the gassing voltage. This innovative approach results in a saw-tooth voltage profile, optimizing the charging process and ensuring battery longevity.
