National New Energy Vehicle Project Team: "Four Points" to See 100 Kilometer Energy Consumption of Electric Vehicles Is the Key to Get Points

Statistics show that in 2016 China consumed 556 million tons of oil, of which about half were consumed by cars. With the shortage of resources and the deterioration of the environment, energy conservation and emission reduction have become the main theme of the current automobile industry development. As a strategic industry of our country, new energy has become an important measure for realizing the sustainable development strategy of the automobile industry. In 2016, the production and sales volume of China's new energy vehicles will reach 60.5 and 608,000 vehicles respectively. According to the “Thirteenth Five-Year Plan”, the cumulative production and sales volume of China’s new energy vehicles will reach 5 million vehicles by 2020.

As for the current status of the development of new energy vehicles in China, Wang Binggang, head of the supervision consulting expert group on “Energy Saving and New Energy Vehicles” major national project of the National 863 Program, pointed out at a seminar on lubricants and engine technology trends recently that China’s new energy vehicles are still in During the import period.

He believes that the current cost-effectiveness of the product at the introduction stage is not yet competitive. The government needs to do a lot of work. Subsidies are the main incentives. Infrastructure needs to be built. The industry chain needs growth in the process of consumer cognition. Explore and establish an effective business model, so that by 2020 it will enter a period of rapid development, with policy as the main driving force and market as the main driving force. Products will be competitive in some major areas, and infrastructure will also meet basic needs. In the industrial chain, the subsidy for car purchases will be withdrawn, instead of the conventional environmental and energy incentive policies, companies will establish a number of effective business models, and consumers will have higher awareness and satisfaction.

On the extremely controversial issue of current carbon emissions from electric vehicles, Wang Binggang clearly defined electric vehicles from four aspects.

Wang Binggang, head of supervision consulting expert group of national “energy-saving and new energy vehicles” major project, made a report at the seminar on lubricants and engine technology trends

1. Electric vehicles are not zero carbon emissions

Wang Binggang pointed out that the carbon emissions from China's electric vehicles are not zero emissions. He talked about Tesla being fined for carbon emissions in Singapore. Since Singapore’s power generation from fossil fuels emits carbon dioxide, which means that it uses carbon dioxide emissions, in 2016 the Land Transport Authority of Singapore identified the Tesla Model S as a “non-environmentally friendly vehicle” and levied it on vehicle owners. $15,000 in taxes.

The Land Transport Authority of Singapore refers to the emission of 500 g CO2 at 1 degree as the “carbon emission factor”. The carbon emission factor is multiplied by the Model S 100 km power consumption to obtain the CO2 emissions per kilometre of Tesla. From Singapore's algorithm, it can be seen that electric vehicles that appear to be "zero emission" still have a lot of indirect pollution and emissions from the chain of electricity generation to battery equipment.

“Singapore converted the electricity consumed by electric vehicles into carbon dioxide emissions. As a result, Model S’s carbon dioxide emissions exceeded the standard, and the 100 kilometers of electricity consumption may reach 40 degrees. We must refer to this principle in Singapore.” Wang Binggang said, “Singapore All are petrochemical energy power generation. China's petrochemical energy accounts for 70% of the power generation energy, and renewable or non-petrochemical energy accounts for 30%, which is lower than Singapore's carbon emission factor. China will continue to increase the proportion of renewable energy power generation. ”

2. The carbon emissions of electric vehicles are significantly lower than that of gasoline vehicles

According to Singapore’s carbon emission factor data, fuel vehicles will emit 3000 g of CO2 per liter of oil, from the time they are produced to the entire lifecycle of the vehicle. "Electric vehicles consume about 100 to 100 kWh of energy, and emit 5000-15000 g of carbon dioxide, while the lowest fuel vehicles can reach 5 liters of oil at 100 km. The fuel consumption of SUVs is even as high as 15 liters and the higher ones may reach 18 liters. Oil, which emits carbon dioxide ranging from 15,000 to 54,000 grams.”

It can be seen that the carbon emissions of electric vehicles are significantly lower than the carbon emissions of fuel vehicles, and as the proportion of renewable energy generated increases, their carbon emissions will be lower than the carbon emissions of fuel vehicles. At present, China's carbon emissions from electric vehicles are lower than those from 5 liters of oil. “There is controversy in the industry that electric vehicles are not environmentally friendly, but from these data, it can be clearly stated that electric vehicles are environmentally-friendly products, and the carbon emissions of electric vehicles that consume more than 30 kilometers per hundred kilometers are very low. This is undoubtedly confirmed by us. "Wang Binggang said.

3. Carbon emissions are proportional to energy consumption

Wang Binggang said that the carbon emissions of electric vehicles are directly proportional to the energy consumption of one hundred kilometers. The energy consumption of one hundred kilometers is related to the size of the electric vehicle. The larger, heavier or longer the vehicle body, the higher the power consumption. “When discussing the carbon emission targets, according to the Ministry of Industry and Information Technology, the higher the driving range, the more carbon emissions are given. In fact, the longer the driving range, the heavier the car, the higher the energy consumption per 100 kilometers. Carbon The more emissions there are, the less suitable for rewards. The increase in driving mileage is worthy of recognition as technological progress, but it is not suitable as a basis for carbon emissions awards."

“When establishing a carbon emission credit, the country should link the driving range and the 100 kilowatt-hour electricity consumption. Both have the balance to reward the points. Even if the driving range is longer, if the 100 kilometer power consumption is too high, we still have to This will not only encourage technological advancement in driving mileage, but also take care of the electricity consumption and carbon emissions of 100 kilometers, which is very important,” Wang Binggang pointed out.

4. Carbon emissions from high-power electric vehicles are comparable to low-fuel gasoline vehicles.

According to the calculation of the second point in the preceding paragraph, the fuel vehicle will emit 3000 g of CO2 per liter of oil during the entire life cycle of vehicles that generate electricity for use. The energy consumption per 100 kilometers of high-energy electric vehicles is about 30 degrees, and the emission of carbon dioxide is about 15,000 grams. The minimum fuel consumption of a fuel vehicle can reach 5 liters of oil per 100 kilometers, and the emission of carbon dioxide is only 15,000 grams. It can be seen that high power consumption actually occurs. The carbon emissions of electric vehicles are comparable to gasoline vehicles with low fuel consumption.

In addition to a clear explanation of the current controversial issue in the carbon emissions of electric vehicles, Wang Binggang also emphasized the definition of new energy vehicles. He pointed out that whether to differentiate new energy vehicles from the energy production, storage and transportation process and automobile manufacturing and use process to achieve full life Cycle assessment, there is no absolute clean new energy vehicles, only the relative concept, energy saving means emission reduction.

"China has determined that pure electric drive (including EV, PHEV, and FEV) is the main direction of new energy vehicles, while using technologies such as HEV to reduce car energy consumption, natural gas HEV vehicles also have a good application prospects." Wang Binggang said that the new energy automotive industry In 2020, it is expected to enter a period of rapid development. New energy automobile industry should actively respond to the adjustment of policies, develop products with market competitiveness, accelerate the improvement of infrastructure, and create conditions for large-scale promotion. The government must also continue to improve its policy system to ensure the continued steady development of new energy vehicles.
