Endurance control method of fuel cell vehicle and fuel cell vehicle

Abstract

The invention discloses a method for endurance control over a fuel cell vehicle. The method comprises the steps of determining a current endurance mode which comprises a single power battery power supply endurance mode, a single methanol water reforming hydrogen production generator power supply endurance mode and real-time endurance; if the current endurance mode is the real-time endurance mode, causing a main controller to control a methanol water reforming hydrogen production generator to supply power to a vehicle motor and charge a power battery and a starting storage battery; in the running process, if the charging of the power battery is saturated, performing conversion to the single methanol water reforming hydrogen production generator power supply endurance mode or the single power battery power supply endurance mode; in the running process in the single methanol water reforming hydrogen production generator power supply endurance mode, if methanol water is used up, performing forced conversion of the fuel cell vehicle to the single power battery power supply endurance mode. The invention further provides the fuel cell vehicle controlled by the endurance control method.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a battery life control method of a fuel cell vehicle and the fuel cell vehicle. Background technique [0002] At present, the vast majority of automobiles use gasoline and diesel as fuel, which not only consumes a large amount of oil resources, but also causes serious air pollution due to automobile exhaust. To deal with this resource problem and environmental problem, the development of electric vehicles has become very important. An electric vehicle refers to a vehicle powered by an on-board power supply and driven by a motor to drive the wheels. Electric vehicles include pure electric vehicles, hybrid vehicles and fuel cell vehicles. In the prior art, a fuel cell vehicle refers to an electric vehicle equipped with a fuel cell as a power source for driving power. In the process of power generation, fuel cells need hydrogen as an electrochemical reaction material. ...

AI Technical Summary

Problems solved by technology

However, there are deficiencies in the existing fuel cell vehicles: one is the lack of an effective battery life control method, that is, the battery life of the fuel cell vehicle is not good due to improper management of the battery life control during the driving process of the fuel cell vehicle. Second, the existing above-mentioned fuel cell vehicles use hydrogen directly, so there are certain limitations in the fuel cell part. Vacuum system and liquid level detection, the effect of hydrogen production and power generation is not good, and the hydrogen production equipment is easy to wear and tear, and the service life is not long
