Wang Binggang: Three Standards to Measure Hybrid Power

With the strengthening of people's awareness of environmental protection and energy conservation and the increasingly prominent world energy crisis, hybrid vehicles have increasingly attracted the attention of the market. At the same time, there are more and more hybrid models, but as a consumer, it may not be clear what kind of hybrid power is good. Wang Binggang, a consultant of the Society of Automotive Engineers of China, believes that there are three criteria for measuring hybrid power and emissions, vehicle performance, and reliability.

Three standards

Q: Do you think about a hybrid system or consider whether a hybrid vehicle is worth recommending, or is there a standard for success?

Wang Binggang: The purpose of hybrid design is to reduce fuel consumption, so the first measure of its effectiveness is its ability to save energy and reduce emissions. Among these, energy conservation is the most direct benefit of the province. Second, in terms of vehicle performance, it should be the same level as traditional cars. In the end, its reliability is better. In particular, how long the battery life is, how long the battery can last is also important.

Q: When I read the introduction, I said that the Q5 hybrid quattro has a uniform speed of 60 kilometers per hour in the pure electric mode. It can only travel 3 kilometers. Do you think this quantity is large or small? Can this be used as a measure?

Wang Binggang: Pure electric mileage is enough. It takes a long time for you to go. You have to increase the battery, but if you increase the battery, you will increase the weight, which is actually meaningless. In general, hybrid batteries should not be made too heavy and not too heavy. The battery can support the car for a few kilometers. I think it is reasonable.

Q: What do you think of the hybrid Q5 hybrid quattro?

Wang Binggang: Technically speaking, the biggest advantage of hybrid vehicles is fuel economy. The comprehensive condition of the Q5 hybrid quattro is 20% more than that of the non-hybrid Q5. In addition, the Q5 hybrid quattro power has also increased. This is very good.

Special feature

Q: Compared with the Japanese hybrid car, what's special about Audi's hybrid technology?

Wang Binggang: The Q5 hybrid quattro belongs to deep mixing and Audi calls it “full mixing”. An important sign of deep mixing is that there is a pure electricity model, that is, the engine does not start driving a car. Q5 and Toyota's development philosophy is not the same. As a luxury car brand or luxury brand, Audi must first ensure that the user's driving experience, not because of the electric, and changed the original driving philosophy. It has developed hybrid power based on the concept of driving.

Q: But what is the loss of the battery or where? For example, the battery capacity, the battery thickness, weight, mileage will have a loss?

Wang Binggang: The capacity of the battery itself does not mean that it must be increased blindly, because after all, the hybrid is a car in the middle transition. Later, we will see that there are many new technologies on the basis of hybrid power. For example, the electric series includes plug-in hybrid, step-up internal combustion engines.
