The so-called hybrid power usually refers to hybrid power of gasoline and electricity, that is, mixture of fuel (gasoline, diesel, etc.) and electricity. A hybrid vehicle is a vehicle that has an electric motor as engine's auxiliary power.
Hybrid vehicles offer excellent fuel economy and excellent driving performance. The engine in hybrid vehicles uses fuel, and when starting off and accelerating, fuel consumption can be reduced with help of electric motors. Simply put, it's fuel bill. smaller compared to cars of same size.
Besides, electric motor that assists engine can generate more power at moment of starting, so owner can enjoy more powerful starting and acceleration. At same time, a high level of fuel economy can be achieved.
Working principle: When car starts moving, battery is fully charged, and its output power can meet requirements of car, and auxiliary power system does not need to work. When battery charge falls below 60%, auxiliary power system is activated. When vehicle's energy demand is high, auxiliary power system and battery provide power to drive system at same time. When vehicle's energy demand is low, auxiliary power system provides power to drive system and also charges battery. Thanks to presence of battery, engine runs in a relatively stable operating condition and its emissions are improved.
There are currently three main types of hybrid vehicles:
"Parallel mode" is a hybrid mode in which engine is main motor and electric motor is auxiliary.
The other is "hybrid mode" in which only electric motors are used to drive at low speeds, and motor and electric motors are driven together when speed increases.
There is also a "tandem mode" of electric vehicles driven only by electric motors.
