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 im...

Embodiment Construction

[0016] specific implementation plan

[0017] Further illustrate the present invention below in conjunction with accompanying drawing.

[0018] Figure 1 is a structural diagram of the main part of a fuel cell electric vehicle. The main part is composed of vehicle controller ECU, fuel cell engine, nickel-metal hydride battery pack, drive system, wheels and other components. All components form a distributed control system through CAN bus, and the signal transmission medium is optical fiber. The fuel cell engine is the main energy source of FCEV, which is a system composed of a fuel cell body and a DC / DC converter. The Ni-MH battery pack is used as an auxiliary power supply, and its functions are: ①Provide electric energy when the fuel cell engine is started, ②Provide electric energy when the FCEV accelerates or climbs a slope, ③Recover regenerative braking feedback energy during FCEV regenerative braking, ④Control when the FCEV stops Systems, lighting ...

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...
