So what technology does Tesla rely on to make it a "big brother" in the global new energy automobile industry? That is the battery management system, which is what we call BMS. More than 7, batteries of model 1865 are connected by Tesla's own battery management system, and at the same time, liquid pipes will shuttle between each battery to dissipate the heat generated by charging and discharging. In addition, if a battery has a problem, the system will automatically cut off the connection to ensure the integrity of the whole.
Tesla single crystal cathode battery, which is also a lithium ion battery. It uses a new generation of single crystal NMC532 cathode and a new brand-new electrolyte, which can make the electric vehicle run continuously for 1.6 million kilometers. At present, the battery technology we use can only maintain about 1 times of charge and discharge, and this kind of battery allows 9% of the battery capacity to remain normal after 4 cycles of charge and discharge. Therefore, the single cathode battery can still maintain 9% capacity after achieving a journey of 1.6 million kilometers. This means that if the battery is practical after loading, even if the whole vehicle is scrapped, its battery can continue to be used.
BYD's iron battery is self-developed, which has extremely high safety performance, even if it is thrown into a fire, it will not explode, and the decline rate is very low. The only drawback is that the energy density is low, and the same mass does not store as much electricity as ternary lithium. Now BYD has made adjustments. Pure electric buses continue to use iron batteries, because safety is the first priority. Hybrid and pure electric private cars use ternary lithium. Although the safety is reduced, the storage capacity is improved. And everyone is using ternary lithium. Why don't I use it?
the biggest problem in the development of electric vehicles in the future is how to reduce the battery cost and how fast the cost can be reduced. Tesla Motors is considered as the manufacturer of electric vehicles with the lowest battery cost per kWh. Some analysts in the industry estimate that the company is close to the level of 2 USD/kWh.
