Abstract
The motor vehicle contains a drive assembly (10) having at least one waste heat operating unit (16) and one operating medium reservoir (14). Provision is made such that the operating medium reservoir (14) is at least temporarily operationally connected to the waste heat operating unit (16) for the purpose of heating the operating medium.
Claims14
A motor vehicle with a drive assembly having at least one waste heat operating unit and with an operating medium reservoir, characterized in that the operating medium reservoir (14) is at least temporarily operationally connected to the waste heat operating unit (16) for the purpose of heating of the operating medium.
The motor vehicle as claimed in one of the foregoing claims, wherein the waste heat operating unit (16) is a coolant circulation system (18).
The motor vehicle as claimed in one of the foregoing claims, wherein the waste heat operating unit (16) is part of an internal combustion engine system (10) and/or part of a fuel cell system (12).
The motor vehicle as claimed in one of the foregoing claims, wherein the operating medium reservoir (14) is connected to an internal combustion engine (11) and/or to a fuel cell unit (13) for the purpose of introduction of an operating medium.
The motor vehicle as claimed in one of the foregoing claims, wherein the operating medium is a fuel, hydrocarbon in particular, or hydrogen.
The motor vehicle as claimed in one of the foregoing claims, wherein the operating medium reservoir (14) is in the form of a pressure reservoir or of a cryoreservoir or of a metal hydride reservoir.
The motor vehicle as claimed in one of the foregoing claims, wherein the operating medium reservoir (14) is connected to the waste heat operating unit (16) by interconnection of at least one heat exchanger (22).
The motor vehicle as claimed in one of the foregoing claims, wherein the operating medium reservoir (14) is at least temporarily operationally connected in addition to a latent heat reservoir (24) as heat source.
The motor vehicle as claimed in one of the foregoing claims, wherein the latent heat reservoir (24) is integrated into an operating medium cycle of the operating medium reservoir (14).
The motor vehicle as claimed in one of the foregoing claims, wherein the fuel cell unit (13) is in the form of an auxiliary energy preparation unit.
The motor vehicle as claimed in one of the foregoing claims, wherein the fuel cells (26) are in the form of diaphragm or solid oxide fuel cells.
The motor vehicle as claimed in one of the foregoing claims, wherein a control unit (28) is provided for control of the heat introduced in an operating cycle of the operating medium reservoir (14) as a function of the electric fuel cell charge required in each instance.
The motor vehicle as claimed in one of the foregoing claims, wherein the latent heat reservoir (24) is operationally connected, at least temporarily, in addition to the fuel cells (26) for cold-start heating of such cells.
