Title: Inventor Spotlight: Larry Hayashigawa - Pioneering Innovations in Electric Vehicle Charging
Introduction:
In the world of electric vehicles (EVs) and sustainable transportation, groundbreaking inventors are forging the way towards a greener future. One such visionary is Larry Hayashigawa, a resident of Downey, CA. With an impressive portfolio of 14 patents, Hayashigawa has made substantial contributions to the field of EV charging technologies. Let's explore his latest inventions and his career journey in this enlightening inventor spotlight.
Inventions:
Among Larry Hayashigawa's notable inventions is the portable charging cable with an in-line controller. This invention involves a cord consisting of multiple insulated conductors and a flexible outer sheath, encapsulating the conductors. The cord comprises an EVSE docking connector and a utility plug on the docking and utility ends, respectively. An in-line EVSE controller, housed and sealed within the flexible outer sheath, is positioned between the docking and utility sections of the cord. This portable EVSE unit provides enhanced convenience and functionality for electric vehicle owners.
Another remarkable creation by Larry Hayashigawa is the system for charging an electric vehicle (EV). This method involves receiving a user's authentication code in an electric vehicle service equipment (EVSE) from their mobile device. The code is then compared to a whitelist of authorized user authentication codes in the EVSE. Upon successful authentication, the EVSE enables an EV charging transaction, eliminating the need for concurrent access to an EVSE-related remote server. This innovative approach streamlines the process and enhances user experience during EV charging.
