According to foreign media reports, Tesla’s battery research partner Jeff Dahn’s lab recently published a paper on electric vehicle batteries, which discusses a battery with a service life of more than 1.6 million kilometers, which will be driven automatically. Taxi (Robotaxi) plays an important role. In 2020, Tesla will launch this new battery module.
Earlier, Tesla CEO Elon Musk pointed out that when driving a self-driving taxi, these vehicles must have durable characteristics to generate sufficient economic benefits. Mask said that most vehicles at this stage will be designed with 1.6 million kilometers of operational targets in mind, including the design, testing and verification of vehicle drive units, all of which serve the target of 1.6 million kilometers, but in fact Most of the battery life of electric vehicles cannot reach 1.6 million kilometers.
Earlier in 2019, Musk pointed out that the company’s current Tesla Model 3, its body and drive system life can reach 1.6 million kilometers, but the battery module’s service life is only 480,000-800,000 km. between.
Tesla’s battery research team has done a lot of testing on new batteries and used a variety of methods to check the cause of battery performance degradation. It is reported that the new battery will increase the durability of the battery used by Bitsra two to three. In addition, even in an extremely high temperature environment of 40 degrees Celsius, the battery can complete 4000 charge and discharge cycles. In addition, if equipped with Tesla’s battery cooling system, the number of charge and discharge cycles that can be completed by the new battery will increase to more than 6,000 times. Therefore, a good battery pack will easily reach a service life of 1.6 million kilometers in the future.
After the self-driving taxi is launched, the vehicle will travel all the way around the road, so a nearly 100% charge and discharge cycle will become the norm. In the future commuter travel, autonomous driving and electric vehicles will become the mainstream. If the battery can reach a service life of 1.6 million kilometers, it will reduce its operating costs, and the use time will be longer. Not long ago, the media reported that Tesla was trying to build its own battery production line, and with the release of a new paper from the battery research team, Tesla would soon produce this battery with a long service life.
