At the Tesla Automation Conference held in April this year, the company's CEO Elon Musk revealed that Tesla is developing a new battery pack that can support a vehicle mileage of 1 million miles. Combined with 1.61 million kilometers). Recently, Tesla's battery research partner Jeff Dahn's lab published a paper on electric vehicle batteries. It describes a battery with a service life of more than 1.6 million kilometers. This battery will play an important role in self-driving taxis and is expected to be launched in 2020.
Earlier this year, Musk said that most of the current electric vehicle batteries can't reach 1.6 million kilometers. The Tesla Model 3 body and drive system has a service life of 1.6 million kilometers, but the battery module has a service life of only 48-800,000 kilometers. It is understood that Tesla's upcoming new battery will be 2-3 times more durable than the current battery, even at 40 ° C, the battery can complete 4000 charge and discharge cycles.
In addition, under the support of the Tesla cooling system, the battery has increased the number of charge and discharge cycles 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. It is worth mentioning that Tesla Battery Research Group has applied for a battery patent, which is a new battery chemistry that can speed up charging and discharging, extend service life and reduce costs. Coupled with the release of a new paper from the battery research team, Tesla will soon produce this battery with a long life.
