Knowledge of new energy vehicles
1. Advantages of new energy vehicles
1. Outstanding environmental protection characteristics
Use of new energy vehicles. mainly a fuel-free electric device that uses clean energy such as electricity, solar energy and hydrogen, which significantly reduces emissions of exhaust gases such as CO2, CO and carbon oxides. 'nitrogen.
2. There is no need to worry about number restrictions
Due to the serious pollution of the domestic environment, some cities have adopted car number restrictions to restrict car travel private in order to reduce environmental pressure. . With the advantages of low pollution and low emissions, new energy vehicles are generally not subject to licensing restrictions and are more convenient for travel.
3. Low cost of use
The fuel consumption of a fuel vehicle is approximately 7 liters per 100 kilometers. Calculated based on gasoline 92 No. 9 yuan/liter, the cost of fuel. is more than 60 yuan; while electric vehicles (new energy) consume about 17 kilowatt hours of electricity per 100 kilometers, and the charging cost is less than 20 yuan, which greatly improves the economy.
2. Development prospects of new energy vehicles
By 2030, the development of new energy vehicles will save 73.06 million tons of oil and replace 91 million tons of oil, saving and thereby replacing a total of 16,406 tonnes of oil, which equates to a reduction in automotive oil demand of 41%. By then, biofuels and fuel cells will play an important role in replacing oil in automobiles.
Based on China's energy resource situation and the development trend of international automobile technology, it is expected that after 2025, ordinary gasoline vehicles will only account for 'about 50% of the number of passenger vehicles in China, while advanced vehicles diesel vehicles, gasoline vehicles, etc. New energy vehicles such as automobiles and biofuel vehicles will develop rapidly.
3. Questions and Answers on New Energy Vehicles
Q1: Is the battery life of new energy vehicles decreasing rapidly?
A1: Currently, the most accurate battery attenuation test data is available only from each manufacturer's own model test data published. Industry insiders said: "In general, the mitigation of pure electric vehicles is relatively important.nte in the first year, about 8%, but over the next 2-3 years it will attenuate by 4%, and after 5-6 years it will attenuate by 4%. 1% year by year." It can be seen that the battery degradation is not significant.
Q2: Is battery degradation covered under warranty?
A2: Currently, it is stipulated that during the warranty period (from 8 years/120,000 kilometers), the battery performance should not decrease by more than 20%. Otherwise, the manufacturer will replace it. free charge. However, if the battery attenuation is normal, the manufacturer will generally not replace the battery.
Knowledge of new energy vehicles
<. p>Traffic jams are becoming more and more serious. In less than 10 years, the number of cars in China will reach 200 million. Many cars "drink" about 200 million tons of gasoline per year, which is equivalent to production. total andoil imports in a year.While cars consume fuel, they also emit a large amount of exhaust gases, causing increasingly serious air pollution.
Cars provide comfort to people, but they consume energy and pollute the environment. What do we have to do ? The two major problems of energy consumption and environmental pollution are indeedIn fact, the development and use of automobiles are facing enormous pressure. The solution to this problem perhaps lies in the development of vehicles using new energies.
01. What is a new energy vehicle?
The so-called new energy refers to various new energy methods other than traditional fossil energy, including solar energy, wind energy, nuclear energy, etc. New energy vehicles refer to al vehiclespowered by new energy sources other than gasoline and diesel, such as pure electric vehicles, fuel cell vehicles and other new energy vehicles.
02. Are there other “new” aspects of new energy vehicles?
The reason why new energy vehicles are "new" is not only because of these types of energy, but also because most of them are environmentally friendly and generate zero or low exhaust emissions, making the air cleaner.
03. What do new energy vehicles look like?
In fact, new energy vehicles mostly maintain the appearance of traditional cars, but the internal structure, especially the structure of the energy device and power system, has undergone fundamental changes and can be described as completely new.
In research and developmentelopment of new energy vehicles, which has made substantial progress and promotion is a type of hybrid transportation vehicle. These vehicles still use some traditional fuels, but are also equipped with batteries and electric motors. or use them simultaneously. Another type of cleaner energy, so the two energy sources can be used interchangeably and complement each other. On the one hand, this improves the power of the car, on the other hand, it reduces the consumption of traditional energies. energy and exhaust emissions are also significantly improved.
04. What are the advantages of new energy compared to traditional cars?
Benefit 1:
Energy saving and emissions reduction. It can efficiently convert more than 60% of electricity into kinetic energy of the wheels. An increase of almost 40% compared to vehiclesessence. Compared to fuel vehicles, it reduces emissions of harmful gases such as hydrocarbons and carbon monoxide and reduces air pollution.
Benefit 2:
More comfortable, less noise, smoother ride and faster speed increase.
Advantage 3:
Save a lot of money, the electricity bill is cheaper, the maintenance cost is low, and the three electricity supplies are guaranteed.
05. How can we ensure the correct method of charging electric vehicles?
1. Observe frequent charges and shallow charges when charging to understand the vehicle charging time and frequency. Charge when vehicle battery capacity is less than 15%-20%. Excessive discharge will shorten battery life.
2. When you have enough time, prioritize slow charging mode to increase the durationbattery life. If it's cold, don't charge quickly first. You can charge the battery slowly first to keep it in good condition, then charge it quickly.
06. What are the daily maintenance items for electric vehicles?
Electric vehicles rely on batteries to provide power and motors to drive. Only the battery and motor require maintenance.
Engine room: Inspection of the engine room should be carried out by professionals. Protective work should be carried out to check whether the engine room wiring harness is aged or has false connections, etc. Please remember that water is not allowed to clean the passenger compartment.
Battery: As the power source of new energy vehicles, it should be inspected and maintained regularly. Improper daily use will cause battery loss.
Antifreeze: Antifreeze in electric vehicles is used to cool the engine and should be replaced regularly within the time frame specified by the manufacturer.
