For hybrid power, refer to that those use traditional fuel, while being equipped with motor/engine to improve low speed power output and combustion
The vehicle of oil consumption, fuel cell car refers to hydrogen, methanol etc. for fuel, electric current is generated by chemical reaction, by electricity
The automobile of machine driving, hydrogen car are a kind of vehicles for really realizing zero-emission, and what is given off is pure water, tool
There is pollution-free, zero-emission, the advantages such as rich reserves, therefore, hydrogen car are the optimal alternative solution of orthodox car, combustion gas
Ingredient is single, purity is higher, can with air uniformly mix combining combustion it is complete, the discharge amount of CO and particle is lower, and engine is low
Starting and behavior in service when warm is preferable, using the inertia energy storage of flywheel, the complementary energy and vehicle of engine when storing non-full load
Energy when long and steep downgrade, Reduced Speed Now generates electricity in feedback a to generator, then and drives or accelerate flywheel rotation.
Since the mechanism used is more than smooth automobile in the structure of new-energy automobile, therefore the installation position between each component
To set particularly significant, the battery installation of especially Electric power car will be fixed, and it is convenient to insert disassembly, and the storage of existing new-energy automobile
Battery is the fixed form using bolt fastening, cumbersome in the dismounting and change of maintenance, is unfavorable for user of service's use, thus compared with
Certain influence is brought during use for inconvenience, secondly its shock resistance will be infused during battery installation
It resits an exam worry, avoids battery connecting line from causing to fall off due to shaking for a long time, and battery itself should also avoid common shaking
Damage is generated, or is detached from original installation site.
Summary of the invention
