  • Patent number: 10534028
    Abstract: An apparatus and method for identifying a presence of a short circuit in a battery pack. A fault-detection apparatus for a charging system that rapidly charges a collection of interconnected lithium ion battery cells, the safety system includes a data-acquisition system for receiving a set of data parameters from the collection while the charging system is actively charging the collection; a monitoring system evaluating the set of data parameters to identify a set of anomalous conditions; and a controller comparing the set of anomalous conditions against a set of predetermined profiles indicative of an internal short in one or more cells of the collection, the controller establishing an internal-short state for the collection when the comparing has a predetermined relationship to the set of predetermined profiles.
    Type: Grant
    Filed: November 22, 2016
    Date of Patent: January 14, 2020
    Assignee: Tesla, Inc.
    Inventors: Sarah G. Stewart, Christopher Dangler, Clay H. Kishiyama, Weston A. Hermann, Scott I. Kohn, Kurt R. Kelty
  • Patent number: 9728990
    Abstract: A system and method for early identification of an impending fast-charge or fast-charge opportunity and use of that information to prepare the battery cells for the fast-charge.
