Abstract
A hybrid vehicle having an electric drive with a power accumulator, a fuel cell, and a control unit configured to control the operation of the fuel cell. The control unit has logic, at least partially including hardware configured to activate and deactivate the fuel cell as a function of a first characteristic map having a first input variable representing a present power demand of the hybrid vehicle which exists over a first defined observation time range.
Claims18
A method for operating a fuel cell of a hybrid vehicle having an electric drive having a power accumulator configured to charge the fuel cell, the method comprising:
- activating and deactivating the fuel cell as a function of a first characteristic map having a first input variable representing a present power demand of the hybrid vehicle which exists over a first defined observation time range.
A hybrid vehicle, comprising:
- an electric drive;
- a power accumulator for the electric drive;
- a fuel cell, and a control unit configured to charge the power accumulator;
- and
- a control unit having logic, at least partially comprising hardware configured to:
- activate and deactivate the fuel cell as a function of a first characteristic map having a first input variable representing a present power demand of the hybrid vehicle which exists over a first defined observation time range.
