Most battery advances concentrate on improving hardware, but researchers from the University of California San Diego have developed new algorithms that can cut lithium-ion battery charge times in half. Usually battery behavior is tracked by monitoring voltage and current, but according to the researchers relying on those measures leads to over-designed, oversized batteries that weigh and cost more. Instead, the San Diego researchers have been developing complex algorithms that can estimate where lithium ions are within cells to more accurately predict battery health.
