Patents by Inventor Thomas LICHIUS

Thomas LICHIUS has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10982584
    Abstract: The disclosure relates to a method for operating a drive device of a motor vehicle, wherein the drive device has at least one heat-generating device and a cooling circuit for cooling the heat-generating device, and at least one first coolant cooler of the cooling circuit and at least one second coolant cooler of the cooling circuit are fluidically connected to the heat-generating device. It is thereby provided that the first coolant cooler and the second coolant cooler are fluidically connected in parallel to the heat-generating device, and that coolant arriving from the heat-generating device be divided by means of a control mechanism between the first coolant cooler and the second coolant cooler. The disclosure furthermore relates to a drive device of a motor vehicle.

  • Patent number: 10946712
    Abstract: A vehicle includes a fuel cell unit with which is associated a first coolant circuit, with a second coolant circuit associated with the interior of the vehicle, in which is held a coolant of lower temperature relative to the coolant of the first coolant circuit. Given higher demand for cooling capacity in the first coolant circuit, a valve is opened by a control device, independently of the heat demand in the second coolant circuit, to open a first connecting conduit between the first coolant circuit and the second coolant circuit, and thus, using a second connecting conduit, forms a common ring conduit for the first coolant circuit and the second coolant circuit with the accumulated coolant from the first coolant circuit and the second coolant circuit.

  • Publication number: 20200388864
    Abstract: A vehicle is provided having a vehicle front end in which a fuel cell system which has a fuel cell stack is arranged, which full cell system is, at a cathode side, connected at least directly to an exhaust-gas line through which a fluid emerging from the fuel cell stack can be discharged from the vehicle front end. The exhaust-gas system comprises a sorption system for the adsorption of a liquid of the fluid emerging from the fuel cell stack. The invention furthermore relates to a method for treating a fluid of a fuel cell system, which has a fuel cell stack, in a vehicle.
