How long is the life of the Tesla lithium battery pack?

Tesla lithium battery pack life Tesla has paid more attention to the body and drive system after launching the autopilot taxi. The current 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 480,000-800,000 kilometers. If the life of the battery module is increased to 1.6 million kilometers, it will greatly reduce the operating cost of autonomous taxis and increase the length of use. At this stage, most vehicles will take into account the 1.6 million kilometers operational target when designing, including the design, testing, and verification of vehicle drive units, all of which serve the 1.6 million kilometers target, but in fact, the current electric vehicle battery is large. Part of the service life cannot reach 1.6 million kilometers. The conventional internal combustion engine needs to be matched with the corresponding transmission system, gearbox system and engine system, but electric vehicles do not need these. The three electric vehicles can ensure that the vehicle has been driven in a high-performance manner. Tesla's theoretical endurance performance under the background of technology promotion In fact, it is easier to implement than the internal combustion engine. Of course, the biggest problem to overcome is the problem of lithium battery packs. This is the biggest bottleneck. Once the battery pack becomes the largest tow fuel bottle, its 1.6 million kilometers target will be far away. After all, once the maximum kilometers of electric vehicles reach 1.6 million kilometers , Which is destined to have a longer life than the engine! The understanding of the life of Tesla lithium battery packs should be based on the understanding of the battery structure. In the process of charging and discharging, the less lithium ions participate in the movement each time, the less damage to the structure. The slower the lithium ion that participates in exercise each time, the less damage to the structure. If the lithium ion is almost running, and the lithium ion is continuously extracted from it, it will damage the battery. The more unstable the structure is, the more it is destroyed, and the cycle life will naturally deteriorate. Therefore, we usually emphasize that the charging and discharging of lithium batteries should be shallow charge and shallow discharge, and do not challenge the limits of the battery.
