Tesla makes million mile battery life

Tesla makes million mile battery life

According to a published scientific study, there is some truth in this statement by Elon Musk.

Many of Elon Musk’s promises remained unfulfilled. For example, his promise to transfer Tesla shares to private hands at $ 420 for each, which turned out to be a joke, to entertain his girlfriend. However, he may have been telling the truth when Musk announced at the Tesla Autonomy Day event in April that the company would soon have a car with a battery of one million miles.

A document released this month by a team of researchers from the University of Dalhousie in Canada describes just such a battery and corresponds to the time Tesla filed a patent. The exact timing for the research work and the Tesla patent is not a coincidence. The Dalhousie team that published the study has an exclusive agreement with Tesla, and one of the researchers, physicist Jeff Dan, is listed as the inventor of the Tesla patent.

The battery design described in the published article can withstand 4000 cycles of full charge – discharge with a loss of capacity of less than 10% over the entire service life. The document concludes that this technology will allow the creation of batteries that will operate on an electric vehicle for more than one million miles or for two decades if the batteries become part of the network’s energy storage system.

According to Elon Musk on Twitter, the battery currently available on the Tesla Model 3 is rated for approximately 1,500 charge cycles, or 300,000 to 500,000 miles. In general, electric cars are still new enough for the market, so we have not yet seen that any instances in a significant amount have fallen due to loss of battery capacity.

According to Nissan, the batteries in its Leaf models, which have been sold since 2010, have been running for so long that the company has developed plans to restore and reuse the batteries when owners are ready to buy a new car.

This kind of battery life will be useful in commercial vehicles such as taxis and semi-trailers, which not only accelerate several miles faster than private vehicles, but are also more likely and more likely to fully discharge and recharge their batteries (as the study notes , most commuters use only about 25% of their EV battery capacity daily). Tesla says it plans to start manufacturing an electric product by the end of 2020.
