Paul H. VROOMEN has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Electrically rechargeable, dual chemistry, battery system for use in plug-in or hybrid electric vehicles
    Patent number: 9774204
    Abstract: An apparatus, method and system are disclosed, relating to a dual-chemistry battery subsystem having different battery chemistries and performance properties, and relating to an algorithm of charging and discharging the battery subsystem. For an EV application, the battery subsystem is a tailored solution that combines two different battery configurations, a first battery configuration and a second battery configuration, to satisfy the unique needs of different driving modes and performance profiles of an EV, such as a typical workday commute versus an occasional extended range trip on the weekend. The present disclosure provides intelligent control and heuristics to maximize useful energy on a wide variety of battery applications.
