As a Vacuum Brake Booster System Factory, I want to share with you.
I. Energy-saving and emission reduction is the purpose of electric vehicles
Energy-saving and emission reduction should be measured from the entire cycle of electric vehicles, not which segment. For example, when driving on the road, pure electric vehicles use electricity, and fuel electric vehicles use hydrogen, not this. Let's talk about where electricity comes from and where hydrogen comes from, and how does it save energy and reduce emissions. So consider the whole cycle. Then, after considering the whole cycle, the following views emerged.
Vacuum Brake Booster System
Long mileage pure electric vehicle-no energy saving and emission reduction
Plug-in hybrid vehicle-no energy saving and emission reduction
Fuel cell electric vehicles-difficult to save energy and reduce emissions
Miniature pure electric vehicle-true energy saving and emission reduction
Extended range electric vehicle-very energy saving and emission reduction
1. Why is it said that long mileage pure electric vehicles do not save energy and reduce emissions?
This is a pure electric vehicle. Although it saves fuel, it consumes a lot of power, and the power of the power grid mainly comes from coal. Such long-range passenger cars cannot reduce emissions. Although pure electric vehicles do not use oil, they have been fined in Singapore. Our company also sells EV Vacuum Pumps.
Singapore bought a car from Hong Kong and shipped it to Singapore. It originally wanted to get a reward of about 10,000. As a result, the Singapore government tested its power consumption. Judging from its power consumption, not only was it not rewarded, but it was also punished. It cost him ten thousand dollars. Therefore, Singapore's policy is correct. Because of the pursuit of long mileage, a lot of batteries are installed. The more batteries are installed, the heavier the car is. The more power is consumed by the car, the more carbon dioxide and other harmful substances are emitted during power generation. There are many, so Singapore's policy is based on energy conservation and emission reduction, which truly reflects the original intention of developing electric vehicles.
Even in the future, the power of the grid will mainly come from clean energy such as solar energy, high-energy batteries will pass, and long-range pure electric vehicles may not be desirable.
More batteries have higher specific energy and greater explosion risk;
Install more batteries, consume more power for battery production and disposal of waste batteries;
Install more batteries, drive with loads, waste energy;
Large battery usage, high car prices and low competitiveness;
The battery life is shorter than that of the entire vehicle, and users need to pay for the new battery.
The current battery is generally guaranteed for five years, the long warranty is eight years, and a car is driven for more than ten or twenty years, so a car must be equipped with two to three batteries. When buying a car, you don’t value the license money now. There can be subsidies. But did the buyer consider the second and third batteries to be paid out of their own pocket?
Another is that the charging piles must be dense, both costly and occupying land, and it is difficult to meet the requirements. Therefore, the long-distance electric vehicle first deviates from the purpose of developing electric vehicles to save energy and reduce emissions. The second is that users spend more money. After the subsidies are canceled, Poor competitiveness. So the reason why it does not save energy and reduce emissions is here.
