Before I knew it, there were more and more trams on the streets, and many of my friends around me drove them. Everyone talks about how the tram is environmentally friendly and how to save energy, which makes me itch in my heart. I wanted to buy a tram to try it, but when I saw the 8 major injuries of the tram summarized by the god on the Internet, I didn't want to buy a tram for a while.
Compared with traditional fuel vehicles, the insurance cost of trams is about 2,000 yuan more per year, which is a lot higher. This is mainly due to the fact that most of the trams are sold at a higher price, and it is natural for insurance companies to take this into account when calculating premiums.
In addition, the relatively high payout rate after the tram accident also leads to the premium**. In addition, the integration of trams is high, and maintenance is more troublesome and complicated, so the maintenance cost will naturally go up.
Not to mention, you also have to buy some additional exclusive insurance for trams, such as external power grid failure loss insurance, self-use charging pile loss insurance, self-use charging pile liability insurance, etc. Their existence undoubtedly increases the insurance burden of car owners.
Although tram technology is constantly improving, at present, small pure electric vehicles have generally reached a range of more than 200 kilometers, and the range of mainstream models has reached more than 500 kilometers, but compared with oil vehicles, a tank of fuel can easily run 708 kilometers, there is still a big gap. This means that when driving a tram for a long distance, car owners will still be very anxious and have to look for charging piles everywhere, which is really aggrieved.
Don't look at the range data given by car manufacturers, they are all beautiful, but they are often very different from the actual data. Especially in extreme weather such as low temperature, rain and snow, the battery life shrinkage is even more serious. For example, the freezing rain or blizzard in Henan, Hubei, Hunan and other places before the festival made many trams lie directly on the highway.
Although there are many charging stations now, their coverage is still far from that of gas stations. Especially in remote areas, the problem of charging is still a headache.
In addition, although many electric cars now support fast charging, but not all charging piles are fast charging piles, statistics show that only about 57% of the country's public charging piles are fast charging piles, and the rest are slow charging piles. The thought of having to wait for hours on each charge can be painful.
Besides, even if you use a fast charging pile, it will take about half an hour at the earliest, which is still too much worse than a fuel truck that can fill up a tank of fuel in two or three minutes.
There is also the battery life of the tram, which is also a big problem. Under normal circumstances, the service life of lithium batteries should be more than 6 years. But in reality, many car owners may need to replace the battery in two or three years.
As for the reason, it is mainly caused by the bad habits of car owners, such as frequent use of fast charging, continuing to drive in a state of power loss, etc., which will cause damage to the battery and shorten its service life.
On the surface, these seem to be the problems of the owners themselves, but if it weren't for the inherent defects of the lithium battery itself, would the owners have these problems? Apparently not.
The three-electric system (battery, motor, and electronic control) of the tram has a complex structure, and once there is a problem, the maintenance cost is often very high. Moreover, 4S shops tend to prefer to replace parts rather than repair when dealing with tram problems, why? Because they may not know how to repair it, they can only replace it, which undoubtedly further increases the cost of repair.
The speed of replacement of trams is very fast, which directly leads to the decline of their value retention. Coupled with the immaturity of the production process, the quality of the trams on the market is uneven, which also affects its performance in the second-hand market. In addition, manufacturers frequently reduce prices in order to achieve the highest price, which also has a great impact on the value retention rate of trams.
Statistics show that the average value retention rate of 3-year-old gasoline vehicles is as high as 65%, while the value retention rate of 3-year-old pure electric vehicles is only 397%, which is a far cry.
The news of spontaneous combustion of trams occurs from time to time, which undoubtedly makes car owners worry and uneasy every time they drive the trams. The reason for this is that although this is related to the improper charging methods of car owners, more importantly, the safety risks of lithium batteries themselves cannot be ignored. If you want to completely solve this problem, you need to eliminate lithium batteries and use new batteries, but the new battery technology is still in the research and development stage, and there is still a long time before mass production and installation.
All in all, although trams have obvious advantages in terms of environmental protection and energy saving, there are still many problems in terms of insurance costs, cruising range, charging convenience, battery life, maintenance costs, value retention rate and safety. These problems need to be solved by the joint efforts of the state, manufacturers and the whole society.
As consumers, it is recommended that when we choose a tram, we should still understand these hard problems of trams in advance and be mentally prepared, so that we can make a more wise choice when buying a car.
