I have to admit that the domestic automobile market has entered the era of new energy, and it is spreading all over the world with a spark. In this context, the market share of fuel vehicles has also shrunk significantly, so is electric vehicles really the first choice for everyone?In fact, it is not, especially in winter, the problem of battery life shrinkage has become a headache for many car owners.
Under a winter cold wave, all parts of the country have ushered in a big cooling in recent times. However, the most uncomfortable is still in the northern region, with three warnings of cold waves, blizzards, and freezing, and heavy snowfall in many places in the north, and some areas have broken through the lowest temperature value in the same period in history. In such a harsh environment, it also greatly affects the experience of electric car owners, and they dare not turn on the heating casually, and the battery life will be cut in half, so that everyone will inevitably start to scold the "electric dad" again!
In fact, the winter battery life fracture, is also a commonplace problem, even after these years of development, electric vehicles in the battery life, charging and other aspects have been improved and promoted, but can not hide the fact that it is difficult in winter. Some time ago, a winter endurance test will most of the electric vehicles back to their original shape, in the case of minus 20 degrees, the models participating in the test are basically halved in terms of endurance, and some models even achieve only a 30% rate.
In terms of the actual car experience, most car owners are also starting to complain. For example, a car owner scolded angrily on Weibo, "The battery life of 515km is standard, and you can't run 200km if you turn on the air conditioner in winter!."In addition, there are other electric car owners who said, "The winter battery life is really touching, either charging or on the way to charge, and spending the winter is like an electric dad in a catastrophe." ”
It can be said that under the background of the soaring rise in new energy, electric vehicles are the general trend, but how to solve the problem of endurance fracture is also a problem that everyone is facing. From a scientific point of view, electric vehicles on the market are powered by ternary lithium batteries, and the performance of lithium-ion batteries at low temperatures is very sensitive to ambient temperature. It is understood that the principle is that lithium ions are precipitated from the negative electrode through a chemical reaction and move to the positive electrode through the electrolyte, and an electric current will be generated in the process. The low temperature will reduce the speed of chemical reaction in the battery, which in turn will lead to a decrease in the actual operating voltage of the battery and a decrease in the usable capacity of the battery.
In fact, this has something in common with many things we encounter in life, you can understand that if the temperature is too high, the reaction is too intense and easy to get out of control, and if the temperature is too low, the reaction is too slow and the energy is limited. According to research data, when the temperature drops from 25 to -20, the amount of power that can be released by the car's power battery will be reduced by 30%, and the time required to charge will also increase. And in the case of using air conditioning, the range of electric vehicles will also be reduced by 17%, so it is too normal to discount the range in winter.
It is worth noting that electric vehicles not only have the problem of range anxiety, but also their car insurance premium standards are not standardized. According to ** reports, many new energy vehicle owners were rejected to renew their insurance, and many insurance companies said that they could not afford to pay for it, which was too expensive compared to fuel vehicles. This is not an isolated case, because the claim cost of new energy vehicles will be higher than the cost of fuel vehicles, and the battery is a new product, and there is a lack of standards for how to repair and identify.
It is true that from the perspective of future development, electric vehicles do have a lot of advantages, especially in the cost of using the car, which is much less economical than fuel vehicles, plus you can get a green card, exempt from purchase tax, and preferential policies around the country, it is not surprising that many people buy electric vehicles. It's just that in terms of convenience of use, the current electric car can't be compared with the fuel car at all, the heater can be turned on if you want to, and there is no anxiety about battery life, and it is indeed much more reassuring when you go out.
Write at the end
To be honest, it is still too early to completely replace fuel vehicles with new energy vehicles, after all, in terms of convenience, electric vehicles still have a lot of complaints. Of course, at this transition stage, if you want to save fuel and worry, plug-in mixing may be a good choice, don't you think?
