Abstract

The invention discloses a power control method of a fuel cell vehicle, a fuel cell controller and a fuel cell, and relates to the field of battery control. voltage and the current high-side current value and current low-side current value of the bidirectional converter; the theoretical Target current value; analyze the current working condition of the vehicle, and determine the actual target current value in combination with the theoretical target current value; calculate the required air flow into the electric stack at the next moment according to the actual target current value. The invention controls the required flow rate of air, so that the fuel cell vehicle can provide the air volume satisfying the electric stack reaction and ensure the power demand of the whole vehicle when the fuel cell vehicle faces different working conditions.

Description

technical field [0001] The invention relates to the field of battery control, in particular to a fuel cell vehicle power control method, a fuel cell controller and a fuel cell. Background technique [0002] As a big automobile country, my country has a huge automobile market, which brings economic benefits, but also brings huge energy consumption and environmental pollution. With the increasingly fierce competition in the automotive field, various enterprises and universities have begun to engage in research on hydrogen fuel cell vehicles. At present, the key technologies of fuel cell vehicles have been basically broken through, but further improvement and promotion of fuel cell industrialization technology is needed to make the industrialization technology mature. At present, the fuel cell power management collects information such as stack current value and VCU power request value through the fuel cell controller, and obtains the demand value of air and hydrogen entering ...
