Problems solved by technology

The power of the fuel cell is limited by the body, and the rated power is limited
However, when the vehicle is accelerating rapidly, a large current is required, or when the vehicle is suddenly braked, the motor is running in the power generation state, which will also generate a large current
Improper handling of the generated large current will have a great impact on the vehicle, and even damage the vehicle's power unit or other electrical appliances of the vehicle

Abstract

The invention discloses a fuel cell electric vehicle power device with a super-capacitor. The fuel cell electric vehicle power device with the super-capacitor mainly comprises an electric control unit, a power converter, a detection unit, a drive motor, a transmission, drive wheels, a differential mechanism, a fuel storage tank, a separator, an electric control valve, a fuel cell pile and the super-capacitor. When an electric vehicle is accelerated, the super-capacitor supplies power to the drive motor. When the electric vehicle is braked, the drive motor is operated in a power generating mode, the power converter is operated in a rectifying mode, and the super-capacitor is charged by electric energy generated by braking. When the electric vehicle travels normally, the drive motor is operated in an electric mode, the power converter is operated in an inversion mode, and power is supplied to the drive motor through the fuel cell pile. When the electric vehicle travels in an accelerated manner, the drive motor is operated in the electric mode, the power converter is operated in the inversion mode, and power is supplied to the drive motor through the super-capacitor. The separator is further designed, fuel not participating in a reaction is recycled, and the fuel cell electric vehicle power device is more environment-friendly.

Description

Technical field [0001] The present invention involves a fuel cell electric vehicle power device with super capacitors. It uses fuel cells as the initiative of electric vehicles and connected supercapacitors as auxiliary devices. It belongs to the field of electric vehicle equipment. Background technique [0002] Fuel cell vehicle (FCV) is a car generated by electric power battery devices as power.The fuel used in the vehicle fuel battery device is high -purity hydrogen or hydrogen -containing heavy gas obtained by high -purity hydrogen or hydrogen -containing fuel.Compared with the usual electric vehicle, the difference in power is that the power used in FCV comes from the vehicle fuel cell device, and the electricity used by electric vehicles comes from the battery charged by the grid.Therefore, the key to FCV is fuel cells.A fuel cell is a high -efficiency power generation device that does not burn fuel and directly transforms the chemical energy of fuel into electrical energy ...
