What are the usefulness of installing a range extender on an electric vehicle?

Under the current efficiency, the range extender really cannot increase the distance, but the lithium-ion battery is more expensive, so it can still have a certain market space. The range extender survives the chicken ribs between lead-acid batteries and lithium-ion batteries. In the long run, it will be eliminated sooner or later, of course, provided that no new high-efficiency range extender is developed. Calculating an economic account comprehensively considers the price of 1,720 lead-acid batteries is 900 yuan. The popular range extender sold on Taobao is 1480 yuan. The fuel consumption for 100 kilometers is at least 3 liters. The range extender sound is 80 decibels. Calculated if you run 5000 kilometers a year. 150 liters of oil are required. It needs 900 yuan for gas. This range extender also damages lead-acid batteries. Lead-acid batteries are generally shrinking at the present time. If they were so engaged, it could have been used for one and a half years, but it can only be used for one year. So the price came out. 900 for lead-acid batteries + 900 for oil u003d 1800 yuan. Even if the battery is replaced with a new one. The price is 1500 yuan. This cost is also staggering. The price of 7235 lithium-ion battery is 3,500 yuan. Although expensive. But the general warranty is 2 years. Generally it can be used for 3 years. The average price is less than 1,200 yuan. It is estimated that some people will say that my algorithm is too reluctant. Then I count the gas bill as 500 yuan. The lead-acid battery is 500 yuan. The price is 1,000 yuan. But everyone found that I did not include the price of 1480 yuan for the range extender. Calculate when the range extender is scrapped for 10 years. It is still almost the same as the cost of a lithium-ion battery. That is 1148 yuan. The actual situation is that the lead-acid battery electric vehicle with range extender is heavy and noisy (80 decibels) and the 72v35ah lithium-ion battery is very light. The only sound is the sound of the electric vehicle motor. 2. Someone might say that the range extender is a generator, as long as there is oil, it can achieve unlimited endurance. But I say that Sinopec is even cheering. How far are you going to run. If you run 50 kilometers every day, the most important thing you should pay attention to is your wallet. In the case of 7235 lithium-ion battery driving at 60 speed. Can run 60 kilometers in winter. This 60 kilometers is not the itinerary of the joy table. It is the distance measured by gps. It is true and credible. 3. A common phenomenon among people today is that they only consider the immediate price. The price of the range extender is 1480, and the lithium battery 7240 is 3500 (both the price I purchased), and the price difference is more than doubled. Those who have not used both can only look at the store analysis. The range extender analysis is that if there is oil, there is electricity, as long as there is oil for three to five thousand kilometers. Lithium battery analysis is at least more than 100 kilometers at a time, but the maximum can't exceed 200. What do you say users will choose? 4. If there are several types of range extender, it can be charged halfway suddenly, because the battery has been charged for too long, it can temporarily replace it. 5. The voltage of the low-quality range extender is unstable and the battery is damaged from time to time, which affects user confidence. The efficiency range extender was developed.
