Abstract

The invention discloses a fuel cell vehicle hybrid control method. The fuel cell vehicle hybrid control method includes: setting the upper limit value and the lower limit value of the SOC of the power battery; obtaining the SOC value of the power battery, and setting The relationship between the upper and lower limits of the fuel cell to control the opening and closing of the fuel cell; when the fuel cell is in the working state, obtain the expected power demand of the fuel cell and the expected power demand of the power battery; according to the expected power demand of the fuel cell, the power of the fuel cell ‑Efficiency curve and the expected power demand of the power battery, set the actual output power of the fuel cell and the actual output power of the power battery; respectively control the fuel cell and the power battery to output energy to the drive motor and the car according to the set actual output power load. The fuel cell vehicle hybrid power control method of the present invention can effectively improve the total efficiency output of the fuel cell and power battery hybrid power system, and improve the conversion efficiency of hydrogen and electricity.

Description

Technical field [0001] The present invention relates to the field of fuel cells, and more particularly to a fuel cell vehicle hybrid control method and system. Background technique [0002] At present, since fuel cell technology is not mature enough, it has caused high manufacturing costs, making the market for high-power fuel cells that cannot be accepted. It should be noted that the greater the power of the fuel cell, the higher the manufacturing cost, the higher the price of the fuel cell vehicle. [0003] In order to reduce the price of the fuel cell car, the rated power of the fuel cell can be appropriately reduced, and the power output required by the fuel cell vehicle is reducing the price of the fuel cell vehicle to a certain extent. That is, the "fuel cell + power battery" mixed power is used as the power source of the fuel cell vehicle. [0004] It will be appreciated that in a hybrid system consisting of "fuel cell + power battery", it is extremely important for the en...
