About the advantages and disadvantages of new energy vehicles, I'll tell you you a detailed introduction, we take a look at its advantages and disadvantages.
A first, let's talk about its advantages:1. Environmental protection and pollution-freeEnvironmental protection and pollution-free is the most important advantage of new energy vehicles. Traditional automobile emissions are one of the main sources of urban haze, while electric vehicles do not produce any emissions, so the improvement of air quality has a direct help. My city used to have very poor air quality, but since the number of electric cars has increased, the air quality has improved significantly, which makes me even more convinced of the environmental benefits of electric cars.
2. High efficiencyThe efficiency of the electric motor in an electric car is over 90%, much higher than the 20% or so of the internal combustion engine, so energy efficiency is a huge advantage. My monthly electric bill is only about $50, the equivalent of a gasoline tank, and I've been pleasantly surprised by the low cost of charging. The high efficiency of electric vehicles also means saving resources and costs.
3. The direction of development is goodElectric vehicles can use electric energy storage and utilization, can also use new energy sources such as hydrogen fuel cells, do not rely on oil, which is the direction of future development. This flexibility of multiple energy options also makes electric vehicles more forward-looking.
4. Low cost of chargingThe low cost of charging is another advantage. My monthly charging bill is a fraction of the cost of gasoline, about one-fifth of the cost of a gasoline car. Charging is very convenient and economical, which saves a lot of money.
5. Flexibility and convenienceElectric vehicles can control power precisely, much more accurately and efficiently than internal combustion engines. It can also recover braking energy to continue to use, the overall energy saving effect is very good. This precise power control also improves driving pleasure.
6. High comfortHigh ride comfort is also an advantage. Electric cars are virtually noiseless and do not cause fatigue when driving for long periods of time. This can greatly reduce the pressure on the driver of a cab or business car.
The next step is to look at its shortcomings: 1. Few charging pilesThe charging facilities are still not well built, and there is the problem of difficult access to electricity. When I go out, I can't find a place to charge, which causes trouble for me. We need to speed up the construction of charging piles to make charging more convenient, otherwise it will affect the promotion of electric vehicles.
2. Long charging timeThe fast charging technology is not yet mature, and the charging time is too long. I went to a fast-charging station to charge my EV, and I had to wait at least 40 minutes for a full charge. This charging time is too long and not suitable for emergency charging when you are out and about. Fast charging technology needs to be further developed to match the time it takes to refuel.
3. Short rangeShort range battery capacity limits the range of new energy vehicles. My electric car can only last about 200 kilometers on a full charge, and if I want to go out for a long trip, I need to plan ahead for the location of the charging station, otherwise I'll easily run out of power halfway through the trip, which will bring inconvenience to my travels. The technology also needs to further increase the battery capacity, in order to really realize the long-distance travel
4. High battery costsNew energy vehicles have higher battery costs, which affects the price of the car. The biggest cost of buying an electric car is the battery, which directly affects the high price of the car. We need to reduce the cost of batteries in order to popularize new energy vehicles.
5. Weak deceleration abilityThe powertrain makes it a weak deceleration ability. When I drive an electric car uphill, I can clearly feel the lack of power, and the uphill speed is very slow. This needs to be improved through the motor design to increase the climbing power.
6. Cold weather affects battery lifeBattery capacity and range are reduced in cold weather. I use an EV in a northern city, and the range gets shorter every winter. It's important to improve the battery's range in cold temperatures.
The above is my understanding of some of the new energy vehicles, but it has a lot of advantages but there are also some problems, the future needs to be optimized and improved.
