The automobile industry is a traditional industry with a long history, which has been developed in recent decades in the mainland automobile manufacturing industry, and the automobile manufacturing industry in Europe and the United States has a history of hundreds of years. Today, the basic technology of automobile development has been very mature, the body design is also somewhat homogeneous, and the biggest innovation at present is mainly energy. Traditional cars mainly use gasoline, but because oil is non-renewable, and gasoline combustion emits a large number of harmful substances, polluting the environment, automakers are exploring the road to new energy vehicles. To date, the most representative of the field of new energy vehicles is undoubtedly Tesla, elegant design, intelligent driving system and clean energy use have made Tesla a new darling of the automotive market.
However, many of the technologies used by Tesla are not yet mature, and compared with the traditional cars that have been developed for hundreds of years, Tesla's stability is indeed very poor, so the negative news of Tesla has been frequently reported in recent years. Despite this, it is still impossible to stop the enthusiasm of consumers, Tesla's official data shows that Tesla's sales have risen in recent years, occupying a considerable market share. New energy vehicles led by Tesla mainly use electrical energy, but because the car cannot be connected to electricity, it can only be driven by a battery, and the battery can be recharged cyclically, so it can reduce environmental pollution while saving energy. Batteries have many advantages as an energy source for cars, but they are still flawed. The first is the issue of security. If the battery quality does not meet the standard, or there is no mature and stable power control system, the battery in the car is prone to spontaneous combustion accidents, which will endanger the life safety of the driver.
The second is the issue of battery life. Traditional gasoline cars only need to be refueled, but there are many gas stations in the city, which can theoretically have unlimited battery life. Due to the limited battery capacity, the range of new energy vehicles is also problematic, but the charging time after the battery is out of power is long, which will also affect the driving experience. At present, there are two main battery solutions for new energy vehicles. One is a large battery and the other is a size 5 battery. Tesla uses a no. 5 battery solution. Why is that? Tesla uses Panasonic 18650's single 5 battery 7000 units, mainly based on the suppression of body weight, the increase in endurance time, the convenience of maintenance and replacement, cost management and other factors. The first is to control the weight. The car itself has a very large self-weight, driving the car requires a strong power, the heavier the body, the more power is required, and the faster the power consumption.
The endurance of new energy vehicles is not strong. If the body is too heavy, the battery life will definitely continue to shorten. In addition, excessive weight of the body will also affect the driver's sense of experience. A single five-cell battery is smaller than a large battery, and the space occupied in the car is also smaller. Cars can be made more refined, more maneuverable and have a longer battery life. Secondly, it is convenient for the subsequent maintenance and replacement of the battery. The battery life of new energy vehicles is limited, especially in the process of cyclic charging and discharging, the battery life will undoubtedly be consumed quickly. Of course, the parts of traditional fuel vehicles also have a lifespan, and they must be replaced after a long time of use, but the battery consumption of new energy vehicles will be faster. The battery itself is the only driving force for new energy vehicles, and when the battery is damaged, the car cannot move a step. If the large battery scheme is used, if the battery is damaged, a new battery will be replaced, which is very costly. Tesla's single 5 battery method, as long as you detect which battery is damaged, replace the damaged battery, it is very convenient and costly.
Finally, control costs. The cost here is not that Tesla is lazy to use inferior batteries in order to save money. There is no problem with the quality of Panasonic batteries, and they must have undergone rigorous testing before leaving the factory. What is saved here is actually the cost of consumers, and the current battery technology still cannot solve the problem of battery attenuation, and the subsequent sailing distance of new energy vehicles will be greatly reduced for a period of time. In order to operate stably, the batteries of new energy vehicles must be replaced regularly. But you know, the current price of car batteries is not cheap, usually tens of thousands of yuan or even hundreds of thousands of yuan, a domestic new energy vehicle is more than 100,000 yuan. However, the battery has to be replaced when it is out of power, so for new energy vehicle owners, the cost of buying a car is higher than the cost of follow-up maintenance, which is also the reason why many people are reluctant to buy new energy vehicles.
Tesla's single-5-battery solution solves this problem well. Because 7,000 batteries will not be consumed in full, only a part of it can be replaced when replacing, which can save a lot of costs.
