Patent number: 8153290Abstract: One embodiment includes an electrical cell that includes a flat housing, at least one electrode and an electrically and heat conductive tab coupled to the electrode and extending through the housing for electrically and thermally coupling to a collector panel, the tab being capable of conducting both current and a substantial amount of heat out of the housing to a temperature control system. The cells may be stacked to form a battery having a temperature panel interfaced to the temperature control system by a thermal interface. The battery may propel an electrically-powered vehicle or the like.Type: GrantFiled: October 28, 2008Date of Patent: April 10, 2012Assignee: Tesla Motors, Inc.Inventors: Weston Arthur Hermann, Scott Ira Kohn, Kurt Russell Kelty, Clay Hajime Kishiyama, Anil Paryani, Alexander Thomas Jacobs, Grant Dufresne Cutler, Peng Zhou

Patent number: 7579725Abstract: A rotor assembly cooling system (100) and method of using same are provided. A portion of the rotor shaft (103) is hollow, the rotor shaft including an open end (107) and a closed end (105). A coolant feed tube (109) is rigidly attached to the rotor shaft (103) using one or more support members (111), thus causing the shaft and the feed tube to rotate at the same rate. Coolant is pumped through the feed tube until it exits the end of the feed tube and flows against the inside surface of the closed end of the rotor shaft causing the coolant to change direction and flow back through the coolant flow region, this region being defined as the space between the outer surface of the feed tube and the inner surface of the hollow rotor shaft.Type: GrantFiled: December 20, 2008Date of Patent: August 25, 2009Assignee: Tesla Motors, Inc.Inventors: Peng Zhou, Nicholas Robert Kalayjian, Grant Dufresne Cutler, Peteris Koch Augenbergs
