Publication number: 20220009343Abstract: A method for producing a compressed gas tank for a motor vehicle includes inserting a bundle of heat-conducting elements through an opening in a housing of the compressed gas tank and exerting a force on the bundle that radially expands the bundle within the housing beyond the size of the opening. The heat-conducting elements may be helically wound about a central axis when inserted through the opening with a torsional force applied to unwind the elements while radially expanding and reducing axial length of the bundle. A compressed gas tank for a motor vehicle includes a plurality of heat-conducting elements including at least one tube within a tank housing that extend axially along the tank and radially within the housing to a size exceeding an opening of the housing. The tube is configured to circulate coolant to cool compressed gas within the tank.Type: ApplicationFiled: July 6, 2021Publication date: January 13, 2022Applicant: FORD GLOBAL TECHNOLOGIES, LLCInventors: Guenter Hans GROSCH, Bert HOBEIN, Thomas Werner STEINKOPF, Rolf Lorenz LOEFFLER, Julio OROZCO SANTOS COY, Stefan KAIMER, Florian HUTH

Patent number: 10632831Abstract: A fuel cell plug-in hybrid vehicle includes a fuel cell having an anode side and a cathode side with a compressor connected to the cathode side. An electric motor is drive-connected exclusively to the compressor. A converter is connected electrically on one side to the motor and on the other side to a high-voltage battery. A controller switches the vehicle between two different operating states. In a first operating state, the high-voltage battery supplies electrical power to the motor via the converter so that the electric motor drives the compressor. In a second operating state, an electrical voltage is supplied from a power supply system to the motor or to the converter via a power supply line. The motor can modify the amplitude of the system voltage with the modified voltage present across the converter, which converts the voltage into a DC voltage applied across the high-voltage battery.Type: GrantFiled: November 28, 2018Date of Patent: April 28, 2020Assignee: Ford Global Technologies, LLCInventors: Julio Orozco Santos Coy, Arnulf Sponheimer
