Patent number: 9381822Abstract: The electrical vehicle energy storage system permits the electric refueling of the electric vehicle just like an automobile would be refueled with gasoline at a gas station. Circuitry on board the vehicle accessible by the electric refueling station enables the determination of the energy content of the battery module or modules returned to the electric refueling station and the owner of the vehicle is given credit for the energy remaining in the battery module or modules which have been exchanged. Selective refueling may take place for given battery modules by removing them from the battery system and charging them at home, office or factory. A process for operating an electric vehicle is also disclosed and claimed.Type: GrantFiled: April 28, 2014Date of Patent: July 5, 2016Inventor: Karl F. Scheucher

Patent number: 9212966Abstract: Mechanical, electronic, algorithmic, and computer network facets are combined to create a highly integrated advanced gas sensor. A sensor is integrated into switchgear housings. These sensors integrated into high voltage switchgear products, deployed by electric utility end users in replacement and expansion cycles, function to detect and mitigate atmospheric pollution caused by leaking SF6. As its associated gas insulated tank is charged with 10 to 350 lbs. of SF6, each gas sensor monitors its local cache of gas, accurately sensing and computing fractional percentage losses (emissions) and gains (maintenance replacement) in SF6 mass, storing data in onboard data logs, and communicating data when triggered by detection events or in response to remote requests over a hierarchical communications network, a process that continues without labor until a fractional leak is automatically detected and reported creating the opportunity for early leak mitigation.Type: GrantFiled: August 6, 2012Date of Patent: December 15, 2015Assignee: SOLON MANUFACTURING COMPANYInventor: Karl F.
