Gray says working with Hernandez was great for him too — and not just because of his bad wrist. “We can work through the math together to be sure we’re not doing something fundamentally wrong,” says Gray, a junior in electrical engineering. “It’s useful just to have someone to question you and make you justify your ideas.”

James Kirtley, professor of electrical engineering and principal investigator for the RLE project, says he likes to team up students for just this reason. “The very best teachers are students, so it is reasonable to expect that the experienced student will teach the less experienced students what he or she knows,” he says. “And the ambitious but less experienced student will, by asking questions, prod the more experienced student to think more broadly about the problem.”

For Hernandez and Gray, the problem was how to develop an improved cell voltage balancer, a device used to extend the life of batteries by working to ensure that cells remain evenly charged as the battery cycles (charges and discharges current). They were hoping to improve on existing designs, since most balancers today work by dissipating extra charge as heat. As Gray explains, “If the battery management system sees that some cells are more charged than others, it will just waste that energy.”
