Penn State team devises solution for fast charging of Li-ion batteries at cold temperatures

Green Car Congress

Fast charging is seen as a solution for range and recharging time issues for EVs. Now, a team from Penn State has devised an approach that enables 15-min fast charging of Li-ion batteries in any temperatures (even at ? at 0 °C to prevent lithium plating, which explains the long recharge time of today’s EVs at low temperatures.
