  • Patent number: 11745619
    Abstract: Multiple chemistry battery systems and methods for using such systems in electric vehicles are disclosed. In one embodiment, an example electric vehicle may include a drive motor configured to impart motion to one or more wheels of the electric vehicle, a plurality of batteries configured to power the drive motor, and one or more controllers. The plurality of batteries may include a first battery including a first cell having a first chemistry, and a second battery including a second cell having a second chemistry different from the first chemistry. The one or more controllers may be configured to cause the first battery and the second battery to power the drive motor, and to cause the drive motor to charge the first battery and the second battery.
    Type: Grant

  • Patent number: 8661503
    Abstract: A method, system, and computer program product for providing document security for procurement agents. The method commences by establishing user authentication credentials for at least two procurement agents. Then, initially granting limited access to a first set of documents where the first set of documents is initially under control of the first procurement agent (and initially inaccessible by the second procurement agent), and initially granting limited access to a second set of documents, where the second set of documents is initially under control of the second procurement agent. A procurement application receives an access request from the first user to access a document from among the second set of documents, causing the procurement application to confirm the first user authentication credentials, retrieve the document access rule for the first procurement agent, and allow/deny access by the first user to the document from among the second set of documents.
