Returning to the essence, whether it is a fuel car or a pure electric car, the fundamental attributes are all transportation tools, but due to the limitations of technology, the fundamental attributes of pure electric vehicles and fuel cars have made a difference in mobility. Fuel cars can not only meet short-distance The demand for travel can also be adapted to long-distance use, and pure electric vehicles are limited by battery capacity and charging speed, so they cannot meet the needs of long-distance use.
When talking about the shortcomings of pure electric vehicles, many people will put the battery life issue first, because pure electric vehicles can not meet the demand for long-distance use, but the key factor of this problem is not the battery life itself, but supplement The way of energy.
Most traditional fuel vehicles are calculated based on a 50-liter fuel tank and a fuel consumption of 8 liters per 100 kilometers, but the cruising range is only about 500 to 800 kilometers. The PCB editor found that some current technologies are more advanced pure electric Cars can also reach about 500 to 600 kilometers in terms of comprehensive cruising range. The biggest difference between the two is the way of supplementing energy. The former takes only a few minutes to complete, while the latter takes more than half an hour.
It is the inconvenience of charging that has led to restrictions on the use of pure electric vehicles, which cannot meet the comprehensive needs of use, and is only suitable for daily travel. Then the direction of technological development should be placed on the charging technology and method. If it is impossible to break through, then the pure electric vehicles continue to improve the cruising range and still cure the symptoms.
To improve the cruising range of pure electric, most manufacturers' methods are to increase the capacity of the battery, from 40kwh to 50kwh, and then to 60kwh. While the battery capacity increases, if the capacity density does not increase significantly, then it means the battery The self-esteem is constantly improving. One important factor that is easily overlooked is the 100-kilometer power consumption of pure electric vehicles. With the increase in battery capacity, the 100-kilometer power consumption has also increased from 10kwh to 20kwh. Although the battery life has been improved, the energy consumption It becomes larger, and most of the energy is offset by its own weight. This is a waste, which is contrary to the development essence of new energy vehicles.
If the bottleneck of pure electric vehicles cannot be broken through, then it is better to re-examine the development direction of pure electric vehicles. Perhaps this energy method cannot completely replace fuel vehicles. Circuit board factory thinks. From the existing technical stage, pure electric vehicles are obviously more suitable for daily use, and from the needs of most people's vehicles, pure electric vehicles are also very suitable for mainstream people.
Most people's car needs are within 50 kilometers per day, including commuting, shopping, family transfers, etc., if calculated according to a charge once a week, the endurance of 350 kilometers can already meet the demand, if the endurance mileage reaches 600 Kilometers, then it can already be charged once in about half a month, slow charging can only be completed in about 8 to 10 hours, and night charging will not affect any normal use requirements.
While increasing the cruising range and increasing the battery capacity, we should pay more attention to the key data of 100 kilometers of power consumption. At the same time, we should also focus on improving the battery capacity density and changing the supplementary energy method, and simply improving the cruising range. It is difficult to satisfy everyone.
