One of the most challenging tasks for the automotive industry today is to explain to consumers that the future of the industry is no longer the same as before. We urgently need to reduce vehicle carbon emissions to avoid turning this beautiful blue planet into a "hell" that is not suitable for human habitation. This means that cars need to use new energy as a power source, completely abandoning hydrocarbon fossil fuels that are mined from underground and then distilled. A recent report by the NaTIonal Academy of Sciences shows that people are confused about this issue and the spread of real information is limited.
In the past few decades, cars have always been regarded as a very simple thing - the big machine driven by the internal combustion engine. They burn gasoline, sometimes diesel, and even occasionally use liquefied natural gas. Turbochargers or superchargers are sometimes used to inject more air into the combustion chamber, and even more, a Wankel rotary engine is used to control compression and discharge through the triangular rotor rotation motion, compared to conventional reciprocating pistons. The linear motion of the engine is very different. The urgent need to reduce carbon emissions and improve air quality now means more choices in vehicle powertrains.
The National Academy of Sciences report shows that there are many options for vehicle powertrains, and the combination of different options is even more confusing. Entrusted by Congress, the National Academy of Sciences examined the barriers to the application of plug-in electric vehicles (PEVs). The Academy of Sciences divides PEVs into four categories: remote battery electric vehicles (BEVs) such as Tesla ModelS; short-range battery electric vehicles such as Nissan Leaf; endurance plug-in hybrid electric vehicles (PHEVs) such as the Chevrolet Volt (most of the time) It is powered by electric power); mini PHEVs, such as the plug-in BMW i8 (it can be powered by battery only for short trips).
Pam Fletcher, chief engineer of the General Motors (GM) responsible for electric vehicle projects, said that the best way to communicate the real information of electric vehicles to the public is to give people the experience of driving an electric car. Those who already have electric cars and live with electric cars can understand all this, they know that these vehicles are good for themselves. This is like being part of the learning curve, and as time goes by, more and more people will understand the benefits of electric vehicles. If people do not have a real experience, then it is really difficult to explain to them where the benefits are. After all, only practice can be true.
Automotive design also plays an important role. In 2011, Toyota couldn't launch a hybrid Prius (Prius) and achieved good sales, and was hailed as a model for a hybrid sedan that led the new era. Many economists discuss such a topic in the headlines of newspapers or papers - "Focused Conservation: Prius Effect and Purchasing Desire in Environmental Protection." Among them, Steve and AlisonSexton believe that people buy Prius hybrid cars because they are more traditional than the traditional car, the car's unique design conveys a positive signal to protect the external environment. Buying a Prius is a conspicuous consumption, but the information conveyed in this case is environmentally friendly, a concept that is intuitive and wasteful, consuming the Earth's resource team.
However, according to PamFletcher, the information consumers give back to GM is just the opposite. She said: "When we launched the first generation of Volt cars, we received a lot of unexpected feedback. Consumers said they liked the car because it doesn't look like a science project. Based on this information, we The second generation Volt car was designed and manufactured. The main task of this time is to make the car look more mainstream, not conceptualized and sci-fi."
A recent poll conducted by AutoTrader, a US auto trading platform, also confirmed this claim. Most of the respondents expressed the hope that electric or hybrid vehicles would look more like traditional cars.
Of course, consumer awareness is not the only reason that electric cars are not appearing on the road more and more. The lack of extensive public charging facilities is difficult for urban residents who are used to park their cars on the roadside at night, while residents in the suburbs have garages and parking lots to park and charge.
Arstechnica interviewed BrittaGross, GM's senior automotive commercialization strategy leader, on this issue. Does this mean that the city's drivers are destined to have no electric cars in their lives?
BrittaGross said the current data shows that only 3% to 4% of car charging is done in public, 30% is done at work, and the vast majority is charged at home at night. The focus of the media is sometimes reversed. For electric cars, it is necessary to figure out what is most important in their lives. 50% of drivers use their home outlets to charge, and the market is far from reaching the stage of vigorously developing public charging facilities. DC fast charging and public infrastructure are important, but Gross believes that expanding workplace charging may be the job most needed now.
The National Academy of Sciences report made a number of comments and suggestions to the government, calling for stable federal funding to develop batteries with higher energy densities and to make batteries more secure and durable. It also calls for more research to figure out the pros and cons of charging or workplace charging and public charging infrastructure in the home, and to make certain financial incentives for consumers who purchase electric vehicles (reward for different consumer behaviors needs further Research), as well as recommendations for incorporating charging infrastructure into building codes.
The protection of the environment requires everyone's efforts to achieve results. The development of electric vehicles is only the first step. In the future, when there are more and more electric vehicles on the road, it may be the time to achieve results.
