nickel, as an important raw material for manufacturing ternary lithium batteries, has soared in recent days. Wang Cong, director of big data of Shanghai Nonferrous Network, said in an interview recently that due to import and export issues, domestic supply of Nippon raw materials has become a tight situation, resulting in a rise in nickel prices and even causing many companies to stop production. However, this is only a short-term phenomenon. Subsequent import and export issues have been solved, and nickel prices will gradually stabilize.
At present, the demand for new energy vehicle market in China is rising. The increasing improvement of domestic charging infrastructure and the significant improvement of new energy vehicle safety standards have made many consumers feel confident that the rise in nickel prices has led to many new energy vehicle companies adjusting their product prices one after another. The main reason is the increase in battery costs, and people have once again focused their attention on the battery quality issues of new energy vehicles.
The strength fully recognized by the industry - the security guarantee of Tesla batteries
Since Tesla first introduced lithium batteries into the industry, the safety of electric vehicles has achieved a qualitative leap. Initially, the industry generally believed that the 18650 ternary lithium-ion battery could not be managed in large quantities, and Tesla solved this problem through its intelligent battery management system and began to continue to improve the safety performance and life of the 18650 battery.
In order to make the battery cell more stable, Tesla also sets fuses on both ends of each battery cell, each battery brick, and each battery cell. Once the battery overheats or the current is too high, it will be blown off immediately to disconnect the output to avoid affecting the normal operation of the entire battery pack due to abnormal conditions in a certain battery. This means that the battery fire rate of Tesla vehicles is extremely low. Even if an accident occurs in one battery unit, it will not affect other units. It can "suffer" the danger in a timely manner. Whether it is charging or driving in a rainy day, the battery safety can be guaranteed to the greatest extent.
Tesla also successfully applied silicon carbon negative electrode material on the battery cell, greatly improving the energy density of the battery cell and storing more energy in a smaller volume. On the battery pack, Tesla's innovative and developed large module design not only effectively improves the volume utilization rate, but also can accommodate more battery cells, and connects the battery cells in parallel to improve the instantaneous discharge capacity of the battery pack and the range of a single charge.
At the same time, Tesla's BMS battery management system controls the charging and discharging of each battery, adjusts to meet the best performance, while reducing or avoiding damage to the battery during charging. At the same time, Tesla also uses its advanced heat management system to accurately and instantly control the battery pack temperature, so that it can work at the optimal temperature. Even at low temperatures and low battery capacity, the battery cell can maintain balanced consistency, reducing the damage to the battery and the impact of temperature factors on the battery life, and extending the battery life.
has low failure rate and high satisfaction. Tesla vehicles have won the favor of global users
With the industry-leading new energy technology, Tesla has ensured the low attenuation rate of the battery, effectively extending the vehicle's usage time and improving the value retention rate.
According to statistics, after 50,000 miles of driving, most Tesla vehicles (statistically model is Tesla Model S/X/3) have only attenuated by 5%, and after 100,000 miles, it is only less than 10%, and even after 200,000 miles, it is mostly less than 15%.
Official data are also given in the "2020 Tesla Influence Report". The chart shows that after 200,000 miles of driving, the battery attenuation level of Tesla Model S/X remains at around 85%, which is consistent with the above data. The low attenuation of
battery largely determines that Tesla vehicles have an extremely high value retention rate. In the 2021 China pure electric vehicle value retention rate ranking, Tesla Model 3 and Model Y won the championship in the value retention rate of sedans and SUVs respectively, with the annual report value retention rate as high as 72.84% and 78.67%, which has become a "peace of mind" for many consumers when buying cars.
In addition, Tesla's vehicle failure rate is low and the risk rate is low, winning extremely high user satisfaction. In a survey by the authoritative magazine "Consumer Report", a subsidiary of the American Consumer Alliance, Tesla has ranked first on the list of "the most popular car brands in the United States" many times. Tesla owner Ms. Yang said that since she purchased the Model 3 in 2020, she "had not encountered any faults in two years, and she had never paid for an insurance policy. She also saved money and worry-free maintenance, and was very satisfied."
Tesla CEO Musk said, "Safety is Tesla's primary goal." While ensuring the active and passive safety of the vehicle, Tesla also achieves the ultimate in battery safety. At the same time, Tesla has made progress with more industry partners through opening patents, continuously improving the safety of green travel, and allowing leading new energy technology to benefit more consumers.
