FUEL CELL VEHICLE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240136554 titled 'FUEL CELL VEHICLE
Simplified Explanation
The abstract describes a patent application for a fuel cell vehicle that includes a fuel cell stack, a compressor, and a controller to manage the compressor's rotation speed based on various conditions.
- The fuel cell vehicle includes a fuel cell stack to generate electric power for a traction motor.
- A compressor supplies air to the fuel cell stack, with an impeller and motor to rotate the impeller.
- The controller decreases the motor's rotation speed when accelerator-off is detected.
- The rotation speed is decreased at a first deceleration rate when the air outlet pressure is higher than a threshold, and at a second deceleration rate when the pressure is lower than the threshold.

Original Abstract Submitted
a fuel cell vehicle may include: a fuel cell stack configured to generate electric power for a traction motor; a compressor configured to supply air to the fuel cell stack, the compressor including an impeller and a motor configured to rotate the impeller; and a controller configured to decrease a rotation speed of the motor when detecting accelerator-off. the controller may be configured to decrease the rotation speed at a first deceleration rate when an air outlet pressure of the compressor is higher than a pressure threshold, and decrease the rotation speed at a second deceleration rate when the air outlet pressure of the compressor is lower than the pressure threshold, the second deceleration rate being lower than the first deceleration rate.
