How long is the battery life of Tesla model 3 lithium iron phosphate?
The service life of the Tesla Model 3 body and drive system has reached 1.6 million kilometers, but the service life of the battery module is only between 480,000 and 800,000 kilometers. The lithium iron phosphate battery has a longer cycle life, because the lithium iron phosphate battery will only start to decay after the number of charge and discharge cycles is greater than 3500 times.
Tesla's lithium-ion battery pack life Tesla has paid more attention to the body and drive system after launching its self-driving taxi. The current Tesla Model 3 body and drive system have a service life of 1.6 million kilometers. However, the service life of the battery module is only between 480,000 and 800,000 kilometers. If the life of the battery module is increased to 1.6 million kilometers, it will greatly reduce the operating cost of the self-driving taxi and increase the use time.
At this stage, most vehicles are designed with the operating target of 1.6 million kilometers in mind, including the design, testing and verification of the vehicle drive unit, all of which serve the target of 1.6 million kilometers. But in fact, the current electric vehicle battery is large Part of the service life can not reach 1.6 million kilometers.
Conventional internal combustion engines need to be matched with corresponding transmission systems, gearbox systems and engine systems, but electric vehicles do not need these. Through three electric vehicles, the vehicle can be guaranteed to drive in a high-performance manner. In the context of technological advancement, Tesla's theoretical endurance performance In fact, it is easier to achieve than the internal combustion engine.
Of course, the biggest problem to overcome is the lithium-ion battery pack, which is the biggest bottleneck. Once the battery pack becomes the largest fuel tank, its 1.6 million-kilometer goal will be far away. After all, once the maximum kilometers of electric vehicles reaches 1.6 million km, which is destined to have a longer life than the engine!
The understanding of the life of the Tesla lithium-ion battery pack should be based on the understanding of the battery structure. During the charging and discharging process, the less lithium ions involved in each movement, the less damage to the structure. The slower the lithium ions involved in each exercise run, the less damage to the structure. If the lithium ions run almost, and the lithium ions are continuously extracted from it, the battery will be damaged.
