Patent number: 8054038Abstract: A method and apparatus for optimizing the level of battery charging required by an electric vehicle is provided. The system includes an interface for the user to input various travel parameters, such as a travel itinerary, which is then used by the battery charging system during charge optimization. In addition to a travel itinerary, the system may be configured to take into account departure times, road conditions, traffic conditions and weather conditions in determining miles to be traveled as well as the electrical energy per mile conversion factors to be used during optimization.Type: GrantFiled: January 29, 2009Date of Patent: November 8, 2011Assignee: Tesla Motors, Inc.Inventors: Kurt Russell Kelty, Scott Ira Kohn

Publication number: 20100316894Abstract: A system for integrating the venting feature of a battery with a means for simultaneously disconnecting the cell from the battery pack, thereby isolating the cell, is provided. The provided battery interconnect system is comprised of a battery, a connector plate for electrically coupling the battery to a battery pack, and an interruptible electrical connector for electrically coupling the connector plate to a battery terminal vent. The vent, defined by scoring on the battery terminal, ruptures when the internal battery pressure exceeds the predefined battery operating range, causing the interruptible electrical connector to break and disrupt electrical continuity between the connector plate and the battery terminal.Type: ApplicationFiled: July 15, 2009Publication date: December 16, 2010Applicant: Tesla Motors, Inc.Inventors: Weston Arthur Hermann, Scott Ira Kohn, Clay Hajime Kishiyama, Kurt Russell Kelty, Jeffrey Brian Straubel, Vineet Haresh Mehta

Publication number: 20100212338Abstract: A method and apparatus for limiting the adverse effects of temperature on the electrical energy storage system (ESS) of an electric vehicle after the vehicle has been turned off are provided. In general, whether or not coolant is circulated through a coolant loop coupled to the ESS depends on the difference between the ambient temperature and a preset temperature, the preset temperature typically corresponding to the temperature of the ESS.Type: ApplicationFiled: March 18, 2009Publication date: August 26, 2010Applicant: Tesla Motors, Inc.Inventors: Weston Arthur Hermann, Scott Ira Kohn, Kurt Russell Kelty, Vineet Haresh Mehta, Jeffrey Brian Straubel

Patent number: 7782021Abstract: One embodiment of the present subject matter includes a system that includes a battery, an electric vehicle, the battery coupled to the electric vehicle to propel the electric vehicle, and a charging circuit to charge the battery. The embodiment includes a charging cost circuit to estimate a charging cost rate and to turn on the charging circuit. The embodiment also includes a timer circuit to provide a time signal to the charging cost circuit. The embodiment is configured such that the charging cost circuit is to turn on the charging circuit during a first time period in which the charging cost rate is below a first threshold until the battery reaches a first energy stored level, and to turn on the charging circuit during a second time period in which the charging cost rate is above the first threshold.Type: GrantFiled: July 18, 2007Date of Patent: August 24, 2010Assignee: Tesla Motors, Inc.Inventors: Kurt Russell Kelty, Eugene Michael Berdichevsky

Patent number: 7683575Abstract: A method and apparatus for deactivating a bad battery cell from a battery pack for an energy storage system of an electric vehicle is disclosed. The apparatus and methodology includes a clamshell member arranged at an end of the cells and a printed circuit board arranged adjacent to the clamshell member. A collector plate is arranged adjacent to the printed circuit board and a switch is arranged on the printed circuit board. A wire bond is arranged between the switch and one of the cells and a second wire bond is arranged between the switch and the collector plate. The plurality of switches will allow for the identification of the one individual cell having a weak short circuit within the battery pack. Upon identification of the cell with the weak short circuit that cell will have its switch placed in an open position thus electrically isolating the faulty or bad cell from the battery pack.Type: GrantFiled: July 18, 2007Date of Patent: March 23, 2010Assignee: Tesla Motors, Inc.Inventors: Eugene Michael Berdichevsky, Kurt Russell Kelty, Scott Ira Kohn
