At the Tesla Automation Conference in April, CEO Elon Musk revealed that Tesla was developing a new battery pack that would last up to 1 million miles (about 1.61 million kilometers) of vehicles.
Recently, Teslas battery research partner Jeff Dahns laboratory published a paper on electric vehicle batteries. It describes a battery with a service life of more than 1.6 million kilometers, which will play an important role in auto-driving taxis and is expected to be launched in 2020.
Earlier this year, Musk said that most of the current battery life of electric vehicles can not reach 1.6 million kilometers. Tesla Model 3 bodywork and drive systems can last up to 1.6 million kilometers, but battery modules can only last between 480,000 and 800,000 kilometers.
It is understood that Teslas forthcoming new batteries will be 2-3 times more durable than the batteries currently in use, and the batteries will be able to complete 4,000 charge-discharge cycles even at 40 degrees Celsius.
In addition, with the support of Tesla cooling system, the number of charging and discharging cycles is increased to more than 6000. Therefore, the battery packs in good condition may easily achieve 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 chemical composition of batteries, which can speed up charging and discharging, prolong service life and reduce costs. Together with the release of the battery research teams new paper, Tesla may soon be able to produce this battery with a longer life span.
