Energy flow controller of fuel cell electromobile

Abstract

The invention relates to an energy flow controller for fuel battery electric motor car, and the controlling system is composed of pedal, entire controller ECU, fuel battery engine, nickel hydrogen battery package and driving system. The invention is to implement reasonable distribution of energy source between fuel battery and fuel storage battery and enhance and optimize power performance of the whole car. Its character: there is also an energy flow controller connected between the ECU and the driving system, where the energy flow controller is a module in the ECU, its input end is connected with the output end of a fuzzy logic controller (FLC), and its output end is connected with the input end of an electric motor controller in the driving system. It synthesizes advanced techniques in the fields of CAN field bus, fuzzy control, communication, etc.

Description

technical field [0001] The invention belongs to an electric vehicle, in particular to a fuel cell electric vehicle, in particular to an energy flow controller for a fuel cell electric vehicle. Background technique [0002] Automobiles have the reputation of "the first commodity", because the development of the automobile industry can drive the development of many industries. Facing the pressure of environmental pollution, global warming, and energy shortage, governments of various countries are actively looking for and researching environmentally friendly energy to replace existing fuel oil, resulting in various electric vehicles. There are currently three types of electric vehicles: pure electric vehicles, fuel cell electric vehicles and hybrid electric vehicles. A pure electric vehicle means that the vehicle energy source is a storage battery, and the wheels are driven by a motor. And batteries, the advantage is that it can improve fuel economy, but...

AI Technical Summary

Problems solved by technology

A pure electric vehicle means that the vehicle energy is a battery, and the wheels are driven by a motor. The advantage is zero emission, but the disadvantage is that the charging distance is short. If the waste battery is not recycled properly, it will cause greater pollution; the hybrid electric vehicle means that the vehicle energy is gasoline. and batteries, the advantage is that it can improve fuel economy, but the disadvantage is that it cannot achieve zero emissions

Fuel cell vehicles have the characteristics of high efficiency and no pollution. The emissions are water and do not pollute the environment. They are more widely used than pure electric vehicles and have power characteristics comparable to internal combustion engine vehicles. The disadvantage is that the cost is too high
