Patent number: 9248756Abstract: A system for controlling battery charging in a vehicle includes a traction battery and a controller. The controller is configured to charge the traction battery to a SOC that is less than a maximum SOC based on an amount of charge predicted to be received from an anticipated regenerative braking event. The regenerative braking event is anticipated to occur during the next drive cycle. The target SOC may be set such that, upon occurrence of the anticipated regenerative braking event, the traction battery achieves the maximum SOC.Type: GrantFiled: March 7, 2014Date of Patent: February 2, 2016Assignee: FORD GLOBAL TECHNOLOGIES, LLCInventors: Elaine Y. Chen, Jimmy Kapadia

Publication number: 20150136589Abstract: An electrochemical system has two separator plates as well as a membrane-electrode assembly arranged at least in regions between the separator plates. The separator plates and the membrane-electrode assembly each have at least two passage openings for a flush arrangement of the separator plates and the membrane-electrode assembly at positioning devices during the assembly of the electrochemical system. At least one resilient bridge is arranged at the periphery of at least one passage opening for a mechanical butting to the at least one positioning device in such a manner that during the stacking of the separator plates and the membrane-electrode assemblies, the membrane-electrode assemblies center themselves in a direction orthogonal to the stack direction between the separator plates.Type: ApplicationFiled: May 16, 2013Publication date: May 21, 2015Inventors: Horst Gehring, Claudia Kunz, Bernadette Gruenwald, Rainer Glueck, Joachim Scherer

Publication number: 20150129337Abstract: Method for battery replacement in a vehicle (110), which vehicle is equipped with a storage space (150;200;300;400) for a battery (120,122;220;320;420;620), where an opening (151;204;304;404) into the storage space exists under the vehicle, wherein the vehicle assumes a first and a second predetermined position in relation to first and second battery transport devices (130;140) that bring a battery out from the vehicle and a battery into the vehicle. The transport devices are installed at least partly above ground (100) and beside the positions, and in that the batteries are brought along a respective path (121,123) running from the storage space, under a side beam (112) of the vehicle and up to a respective position above ground and beside the vehicle. A device for automatic battery replacement and a storage device for use in a vehicle are also described.Type: ApplicationFiled: April 17, 2013Publication date: May 14, 2015Inventor: Sten Corfitsen

Publication number: 20150079440Abstract: The invention relates to a method for producing electrodes (14) for lead-acid batteries (30). An electrode (14) that has been produced comprises at least one upper and/or one lower frame element as well as a lattice-shaped region (12) that extends away from said upper or lower frame element (9, 10) and has a plurality of openings, the upper and/or lower frame element (9, 10) being of a greater thickness (D) than the lattice-shaped region (12). Said method comprises the steps of: a) producing a profiled strip-shaped blank (2) using a casting method in which the strip-shaped blank (2) is formed, solely by means of said casting method, to have a greater thickness (D) on one side in at least one of the regions (3, 5, 7) which should eventually form the upper or lower frame element (9, 10), than the thickness in regions (4, 6) which should eventually form the lattice-shaped region (12), and b) producing said lattice-shaped region (12) with the openings in a subsequent expanded metal process.Type: ApplicationFiled: March 22, 2013Publication date: March 19, 2015Inventor: Tatjana Reich

Patent number: 8973254Abstract: A system and method for the rapid exchange of batteries in an electric vehicle. The electric vehicle contains a removable battery housed in the vehicle's undercarriage. The electric vehicle moves through the exchange system either by propelling itself or by being propelled by the system. As the vehicle is propelled forward, the removable battery within the vehicle is unlocked from the vehicle and replaced with a charged battery. The charged battery forces the removable battery out of the rear of the vehicle as the vehicle moves forward through the exchange. The vehicle remains powered throughout the exchange process. Once the charged battery is aligned in position under the vehicle and connected to the vehicle through corresponding contacts, the charged battery is located into place in the vehicle's undercarriage and the vehicle is ready for additional driving.Type: GrantFiled: March 7, 2013Date of Patent: March 10, 2015Assignee: Jasper EV Tech, LLCInventor: Peter C.
