New energy vehicles in recent years, walking in the fast lane of development, not only Europe and the United States, Japan and South Korea and other developed countries, the domestic various auto enterprises have their own new energy vehicles plan, and some new energy vehicles to market, there are many kinds of new energy vehicles, we usually see in the street of the different types of new energy vehicles, including electric, thickening of the program, gas-electric hybrid, plug-in hybrid, fuel cell, etc., and the rear of the standard of new energy vehicles are each different, have EV/HEV/PHEV/FCV, representatives for the signs mean?The following power battery pack liquid - cooled plate experts for you to introduce the new energy automobile tail mark meaning.
BEV: pure electric vehicle (represented by tesla Model S, jianghuai iEV and byd qin EV)
The BEV Battery Electric vehicle is a pure Electric vehicle. Its power structure is very simple, only the Battery pack, the Electric motor, the former is responsible for power supply, and the latter is responsible for driving the car forward.Most domestic pure electric vehicles are labeled "EV" instead of "BEV", which is a simplification.The battery capacity of the pure electric vehicle will be large, but the range of the battery will be limited. At present, the range of the mainstream pure electric vehicle is generally 300-500 kilometers.Battery charging, there are a lot of technical problems, it is a kind of energy conversion (electrical energy is converted into chemical energy in the battery in the grid), power battery pack cools the radiator experts say there are a concept of super capacitor, if its capacity can reach the level of the chemical battery, it can realize the rapid and real-time energy reserves, the need for a number of technological breakthroughs.
HEV: gas-electric hybrid (represented by Toyota prius, Toyota corolla, Honda accord hybrid)
HEV (Hybrid Electric vehicle) is the "H - Hybrid" in gas-electric Hybrid system, its structure of different cars have their own ideas on design, the Toyota TSH - III Hybrid system is done well, and Honda I - MMD is bypassing the Toyota's Hybrid system dynamic coupling mechanism, performance is good also, fuel efficiency is high.The power battery pack cools the radiator experts say this kind of new energy car battery capacity does not need to be very big, because the role of the battery is also a drive motor to drive the car but can have internal combustion engine driven generators constantly to recharge the battery, more emphasis is the battery charge and discharge frequently performance and the ability to instantly release energy.
PHEV: plug-in hybrid (represented by BMW i8, Toyota prius plug-in hybrid, roewe eRX5 and byd qin)
PHEV (plug-in Hybrid Electric vehicle) power structure and HEV are similar, are mutual cooperation, internal combustion engine and Electric motors to drive the car forward, but the PHEV increasing external power grid to the function of the battery, the battery capacity of the car will ask more, can satisfy the Electric driving of a long journey.The PHEV will vary according to the proportion of electric motors and engines in driving cars, and each manufacturer's HEV models will have different design styles.Power battery pack cools the radiator experts say supercar world three great god USES the PHEV system, the combination of large displacement gasoline engine and motor, engine is the main driving power, the motor only play an auxiliary role, and in most of the main economy of passenger cars, the main drive car or motor.
EREV: plug-in hybrid (represented by BMW i3 extender, buick VELITE 5, Chevrolet volt)
The Extended Range Electric Vehicles generate electricity from generators powered by internal combustion engines to charge batteries, which then power Electric motors and drive cars.In a plug-in hybrid, the combination of fuel tank + engine + generator has completely transformed into a battery energy reserve system, which is different from a fuel car.EREV never directly involved in the drive motor, the rotating speed, load is very stable, also do not need to variable speed gearbox, a long time in the economic condition of rotating speed, efficiency can reach the limit of the reciprocating piston type internal combustion engine, can saying is very perfect.
FCV: fuel cell vehicle (represented by Toyota Mirai and Honda Clarity)
The FCV (Fuel Cell Vehicle) converts the chemical energy of the Fuel into electricity, providing the energy required for driving and driving the car by an electric motor.Currently, the main fuel type is hydrogen, and Toyota and Honda are developing more in-depth in this field, while FCV cars are not widely expected in the field of new energy vehicles and tend to be marginalized.Experts at the liquid-cooled heat sink in the power battery pack say FCV has great advantages. The combustion product of hydrogen is water.And being able to replenish reserves through rapid refu.
