Patent number: 10807476Abstract: The present invention pertains to an electrical system, in particular designed to be installed on board an electric or hybrid vehicle, whereby said electrical system includes an AC-to-DC converter that includes a rectifier and a DC-to-DC converter, an isolated DC-to-DC converter connected to a high voltage battery, and whereby said electrical system is configured, in a first operating mode, to be connected to an external alternating electricity grid to charge the high voltage battery. Furthermore, the first interface terminals of the DC-to-DC converter are connected to a low voltage battery, whereby said electrical system is configured so that, in a second operating mode, when the electrical system is disconnected from the external alternating electricity grid, said DC-to-DC converter supplies an initial voltage from the high voltage battery to power the low voltage battery.Type: GrantFiled: May 15, 2018Date of Patent: October 20, 2020Assignee: Valeo Siemens eAutomotive France SASInventors: Larbi Bendani, Reda Chelghoum, Benedicte Silvestre, Bruno Condamin, Mimoun Askeur, Massourang Diallo

Patent number: 9937807Abstract: The battery charger comprises: two output terminals (BS1, BS2) between which a battery (102) is designed to be connected; two input terminals (BE1, BE2) designed to be connected to an electrical network (110); two inductors (L.A, L.C) respectively connected to the first input terminal (BE1) and to the second input terminal (BE2); two switching arms (BA, BC) for respectively connecting the inductors (LA, LC) selectively to the first output terminal (BS1) and to the second output terminal (BS2); a control device (120) designed for controlling the switching arms (BA, BC) so as to draw from the electrical network (110) a mains current (iR) in phase with the mains voltage (uR). The battery charger further comprises: a smoothing capacitor (C) connected to the second output terminal (BS2); and a connection device (112) for connecting the smoothing capacitor (C) to the second input terminal (BE2). The control device (120) is further designed to control at least the second switching arm (B.sub.Type: GrantFiled: April 15, 2016Date of Patent: April 10, 2018Assignee: Valeo Systemes de Controle MoteurInventors: Luis de Sousa, Bruno Condamin, Boris Bouchez, Pierre-Alexandre Chauvenet, Benedicte Silvestre
