Separating Charge and Discharge in Measuring Next-Generation Car Batteries
American Institute of Physics (AIP)To better estimate the state of charge in lithium ion phosphate batteries, researchers at Southwest Jiaotong University in Chengdu, China, have recently developed an algorithm that can separately measure the charging and discharging states of the battery. This allows it to function amidst initial inaccurate values and errors in measuring current, as well as distinguish between the performance of each battery in the series.
