Publication number: 20190006859Abstract: System and method for connection of a substitute load in batteries that are adapted to provide electrical power to an external power consuming unit. The batteries are connected to an electrical power consuming element, that is connectable to the batteries in case of undesired disconnection of the external power consuming unit. A controllable switching unit is configured to connect the power consuming element between the anode and the cathode when a load sensing unit senses ‘reduced load’ status of the electrical load between the anode and the cathode of the battery.Type: ApplicationFiled: December 29, 2016Publication date: January 3, 2019Applicant: PHINERGY LTD.Inventors: Menachem POLAK, Yisrael MILLER, Christophe DANG-VAN NHAN

Patent number: 10027000Abstract: An accumulator battery system includes series-connected accumulators with potentials across stages powering corresponding controllers that measure potential differences between terminals of accumulators. A first analog-to-digital converter encodes the potential measured between terminals of an accumulator. A first output delivers a first digital sequence corresponding to the encoded potential difference, logic levels of which are defined by at least two potentials across the first-stage accumulator terminals. A decoder decodes a potential measured by the first control-device from the first digital sequence. A second analog-to-digital converter selectively encodes a potential difference measured between terminals of a second-stage accumulator of the second stage and two potentials of the digital sequence received on the input.Type: GrantFiled: June 25, 2015Date of Patent: July 17, 2018Assignee: Renault S.A.S.Inventors: Michaël Palmieri, Marc Beranger, Sébastien Carcouet, Lionel Cordesses, Alexis Derbey, Michel Mensler, Christophe Dang-Van-Nhan

Patent number: 8160768Abstract: A device for determining a value of a binary item, delivered in a redundant manner by two distinct determination mechanisms, and representative of a parameter of a system, the binary item being equal to a first or a second value when the parameter lies respectively in a first or a second range of values, the first and second ranges of values being separated by a transient range of values in which the transitions of value of the binary item transmitted respectively by the determination mechanisms occur. The system includes a state machine that assigns, when one of the determination mechanisms delivers a binary item devoid of any transition of value on account of a malfunction, respectively the first or second predetermined value delivered by the other determination mechanism, which is operating normally, when the parameter lies in the first or second range of values.Type: GrantFiled: November 21, 2006Date of Patent: April 17, 2012Assignee: Renault S.A.S.Inventor: Christophe Dang Van Nhan

Patent number: 7912791Abstract: A method and device for synthesizing an electrical architecture. The method synthesizes a routing that obtains the following parameters: different configurations of service variants and calculator variants and rate of occurrence of the configurations, a sum of the rates of the configurations being considered as equal to one; component cost characteristics stored and weighted according to their respective rates of increase; and partial or full positioning of the service variants on the calculator variants.
