VEHICLE CONTROLLING START, SHUTDOWN AND RESTART OF FUEL CELL - A simplified explanation of the abstract

This abstract first appeared for US patent application 18180535 titled 'VEHICLE CONTROLLING START, SHUTDOWN AND RESTART OF FUEL CELL

Simplified Explanation

The patent application describes a vehicle with a DC converter connected between a fuel cell and a high-voltage battery, controlled by a fuel cell control unit and a converter controller based on the vehicle start state.

  • The vehicle includes a DC converter that connects a fuel cell to a high-voltage battery.
  • A switching element is connected between the fuel cell and the high-voltage battery.
  • A fuel cell control unit manages the activation state of the fuel cell based on the vehicle start status.
  • A converter controller regulates the operation of the DC converter during start, shutdown, or restart sequences for the fuel cell.

Unanswered Questions

How does the fuel cell control unit determine the activation state based on the vehicle start status?

The patent application does not provide specific details on the mechanism used by the fuel cell control unit to determine the activation state. Further information on this process would be helpful.

What are the specific sequences involved in the initial start, shutdown, and restart of the fuel cell controlled by the converter controller?

While the patent application mentions the existence of initial start, shutdown, and restart sequences, it does not elaborate on the specific steps involved in each sequence. More details on these sequences would be beneficial for a better understanding of the technology.


Original Abstract Submitted

A vehicle is provided that includes a DC converter having a first end connected to a fuel cell, a second end connected to a high-voltage battery, and at least one switching element connected between the first end and the second end, a fuel cell control unit which controls an activation state of a running command for start of the fuel cell based on an on-off state of vehicle start, and a converter controller which controls a running state of the DC converter according to an initial start sequence, a shutdown sequence, or a restart sequence for the fuel cell based on the activation state of the running command.
