Helping EVs keep their cool during the battery weight balancing act

Packing enough energy into a battery to power a car is putting a lot of pressure on the storage devices that, for the last century or so, have mainly been tasked with running small appliances and electronics. The stress is getting to them—manifested in malfunctions, diminished performance and even meltdowns. Researchers at Drexel University are trying to help by taking some of the literal heat off batteries and plotting a more sustainable route for their use in electric vehicles.
