Patent number: 10377257Abstract: A vehicle-mounted charging device (12) includes a vehicle-mounted battery (18), a vehicle-mounted electronic control unit (30) and a modem startup control unit. The vehicle-mounted battery is charged with power supplied from external charging equipment via a charging cable (16). The vehicle-mounted electronic control unit is configured to perform charging communication, relating to charging of the vehicle-mounted battery, with the external charging equipment using an in-band modem (32). The modem startup control unit starts up the in-band modem when the vehicle-mounted electronic control unit performs the charging communication, and that stops a startup of the in-band modem when the vehicle-mounted electronic control unit does not perform the charging communication.Type: GrantFiled: December 27, 2013Date of Patent: August 13, 2019Assignees: TOYOTA JIDOSHA KABUSHIKI KAISHA, SUMITOMO ELECTRIC INDUSTRIES, LTD., SUMITOMO WIRING SYSTEMS, LTD., AUTONETWORKS TECHNOLOGIES, LTD.Inventors: Hiroya Ando, Ryuichi Kamaga, Nobuyuki Nakagawa, Yuta Ochiai, Yukihiro Miyashita, Takeshi Hagihara, Yoshikazu Isoyama

Patent number: 10256511Abstract: Rechargeable cells in cylindrical form are arranged within frames in a honeycomb structure and coupled by connecting straps outside the frames to form cell pack. Several cell packs, an electronic switch and control circuit are integrated into the battery housing. A bus bar extends around the perimeter of the housing. A high density MOSFET switch is coupled between the bur bar and the battery contact. A high power electronic clamp disposed across the battery terminals absorbs or redirects transients. An active, high-efficiency, low-noise cell balance converter or a LC based resonant converter may also be provided. For advanced battery applications a +5V CAN bus interface is provided via two circular connectors. Thermistors are provided for use in a thermal protection scheme.Type: GrantFiled: May 26, 2016Date of Patent: April 9, 2019Assignee: Bren-Tronics, Inc.Inventors: Tullio Clemente, Alan Squillante, Azer Ilkhanov, Jarred Kahn, David Sandler, Henry Paczkowski, Peter J.

Patent number: 10236927Abstract: The invention relates to a protective case apparatus for a mobile terminal, having a case base body having a baseplate region for covering a rear of the terminal. The baseplate region has an abutment area for abutting the rear of the mobile terminal. The case base body also has side walls that are integrally molded on the baseplate region and are each configured to directly abut a respective narrow side of the mobile terminal and thereby to hold the mobile terminal against the abutment area. The case base body has only three side walls and one short side of the abutment area is without a wall. When the mobile terminal is arranged in the protective case apparatus, a narrow side of the mobile terminal that is arranged on the short side is not covered by the case base body.Type: GrantFiled: January 24, 2017Date of Patent: March 19, 2019Assignee: Audi AGInventor: Holger Thiel
