Patent number: 9397375Abstract: A battery assembly is provided that utilizes electrically isolated heat sinks to enhance battery pack thermal management and safety. The battery assembly is divided into groups of batteries, where the batteries within each group are of the same voltage, and where each battery group is serially coupled to the other battery groups. The heat sink is segmented, where each heat sink segment is thermally coupled to the batteries within a single battery group, and where each heat sink segment is electrically isolated from the adjacent heat sink segments. The heat sink segments are thermally coupled to a cold plate, and electrically isolated from the cold plate by a layer of a thermal interface material.Type: GrantFiled: September 25, 2014Date of Patent: July 19, 2016Assignee: ATIEVA, INC.Inventors: Richard Biskup, Benson Tsai

Publication number: 20160179958Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for identifying entities that are related to an entity to which a search query is directed. One of the methods includes receiving a search query, wherein the search query has been determined to relate to a first entity of a first entity type, and wherein one or more entities of a second entity type have a relationship with the first entity; receiving search results for the search query; determining that a count of search results identifying a resource containing a reference to the first entity satisfies a first threshold value; determining that a count of search results identifying a resource having the second entity type as a relevant entity type satisfies a second threshold value; and transmitting information identifying the one or more entities of the second entity type as part of the response to the search query.Type: ApplicationFiled: February 26, 2016Publication date: June 23, 2016Inventors: Peter Jin Hong, Pravir K. Gupta, Nathaniel J. Gaylinn, Ramakrishnan Kazhiyur-Mannar, Kavi J. Goel, Omer Bar-or, Jack W. Menzel, Christina R. Dhanaraj, Jared L. Levy, Shashidhar A. Thakur, Grace Chung, Benson Tsai

Publication number: 20160082861Abstract: A method of operating the thermal management system in a vehicle is provided, where the thermal management system includes a heat exchanger (e.g., a radiator) and a heat source (e.g., battery pack, drive train, power electronics, etc.). After characterizing the thermal management system, whenever the system controller issues a cooling demand an appropriate set of operating settings is determined that minimizes the amount of power consumed by the system's actuators (e.g., blower fan, coolant pump) while still meeting the cooling demand. As a result, the heat source is cooled to the degree required with a minimum expenditure of power, thereby minimizing the impact on driving range and vehicle performance.Type: ApplicationFiled: September 23, 2014Publication date: March 24, 2016Applicant: Atieva, Inc.Inventors: Jean-Philippe Gauthier, Benson Tsai

Patent number: 8920955Abstract: A battery module with high thermal conductivity and its assembling method are disclosed. The battery module includes multiple battery cells, a primary retaining frame, a secondary retaining frame, common electrodes and a heatsink device. The primary and second retaining frames are combined together to constitute accommodation chambers for housing the battery cells and formed with interference flanged to secure the battery cells in position. Upon being inserted into the accommodation chambers, the battery cells are electrically connected to the common electrodes. The heatsink device is then coupled to the primary retaining frame and/or the secondary retaining frame, such that the heatsink device abuts against the top common electrode and/or the bottom common electrode of the battery cells.Type: GrantFiled: December 13, 2012Date of Patent: December 30, 2014Assignee: Atieva, Inc.Inventors: Charles Chia-ming Chuang, Benson Tsai

Publication number: 20140349491Abstract: Methods for improving selective oxidation of polysilicon against silicon nitride in a process chamber are provided herein. In some embodiments, a method of selectively oxidizing a substrate disposed within a process chamber includes exposing a substrate having an exposed polysilicon layer and an exposed silicon nitride layer to a hydrogen-containing gas; heating the substrate to a process temperature of at least about 850 degrees Celsius; adding an oxygen containing gas to the process chamber while maintaining the substrate at the process temperature to create a mixture of the hydrogen-containing gas and the oxygen-containing gas; and exposing the substrate to the mixture while at the process temperature to selectively form an oxide layer atop the polysilicon layer substantially without forming an oxide layer atop the silicon nitride layer.Type: ApplicationFiled: May 19, 2014Publication date: November 27, 2014Applicant: APPLIED MATERIALS, INC.Inventors: AGUS SOFIAN TJANDRA, ROGER BENSON TSAI, MATTHEW SCOTT ROGERS

Publication number: 20140255750Abstract: A battery pack with a compact and robust bus bar assembly is provided. The batteries within the pack are divided into groups, where the batteries within each battery group are connected in parallel and the groups are connected in series. A repetitive sequence of overlapping bus bars is used, with each bus bar comprised of upper and lower segments coupled together via a step segment. The overlapping design allows the upper surface of the upper segment of each of the repetitive bus bars to be aligned within an upper plane, and the lower surface of the lower segment of each of the repetitive bus bars to be aligned within a lower plane.Type: ApplicationFiled: March 11, 2014Publication date: September 11, 2014Applicant: ATIEVA, INC.Inventors: James Jan, Richard J.
