The working principle of the car with hydrogen fuel cell series-parallel hybrid electric system：
1) oxygen in the hydrogen and air in high-pressure hydrogen storing system 2 is sent out in the hydrogen fuel cell system 19 that car carries
Raw redox reaction, produces electricl energy, extra electric energy will flow to power battery 7 and store；When being short of power, power
Battery 7 can individually export energy；When hydrogen fuel is finished, the feed of power battery 7, which is then directly given by external charge mouth 11, to be filled
Electricity；Last various power capacities make driving motor 5 work, and the mechanical energy that driving motor 5 generates is transmitted to through rear axle deceleration mechanism 104
Wheel 106 is driven, bus driving is driven；
2) when field without hydrogenation stations, without charging pile, engine 6 directly works, and can not only pass through power coupler 105
It is transmitted to wheel 106 through rear axle deceleration mechanism 104, persistently drives bus driving, and charge to power battery 7 using generator 6,
So that course continuation mileage greatly increases.
3) control strategy of the system is with the composite structure form difference of dynamical system, and driving mode is different, and vehicle exists
In operational process, it then follows the big basic control target optimal energy distribution of car dynamic property, economy and continual mileage three；Severe work
Under condition, if will cause power battery electricity and hydrogen with pure power mode or hydrogen-fueled system output power and used too fast, work
Pure power mode power battery output power is used when making efficiency and expected mileage number is all lower, therefore starting to walk, to stabilization of speed support
Engine operating is played, according to power battery SOC state of charge to determine whether closing pure power mode, if SOC state of charge is in
Maximum value then preferentially uses pure power mode；Otherwise engine output driving vehicle driving is switched to, power generation can be both passed through
