You’re draining the battery to operate a heater,” adds Less. “You have to keep the battery warm, but the battery itself is where heat comes from.
In a car battery, you don’t want to constrict the flow of ions in any way, which means you don’t want to be driving in freezing cold weather. Modern batteries have been optimized for the least amount of resistance possible, but that obviously doesn’t help us in a polar vortex. The automotive industry uses his facility to build batteries to scale and test new ideas for inclusion in electric vehicles. He’s the technical director at the UM Battery Lab in Ann Arbor, Michigan. The more the resistance goes up, the faster you lose power,” says Greg Less, Ph.D. So the ions move more slowly, which causes more resistance. As it gets colder, the liquid becomes thicker, now closer to freezing solid.
“Ions are traveling inside of the battery between the positive and negative electrodes through a liquid electrolyte. It all comes down to the basic function of a regular old every day battery, something we cell phone addicts take for granted. automakers combined)? And how can this happen in the United States, which federally funds some of the best early-stage battery research in the world? Really, how can this happen to a modern, microprocessor controlled, lithium-ion battery at all? Especially given that the entire auto industry is amid its biggest transformation in a century, investing billions in bids to overtake Tesla (NASDAQ: TSLA)? Why does cold weather damage performance this badly in a Tesla, the world’s electric-car leader with a market cap of more than $673 billion (more than all U.S.
