Li-Ion Battery Researchers Work To Improve Precision Measurements of Charging, Estimations of Cycle Life; Highlight Need For Further Order of Magnitude Improvement In Accuracy

Green Car Congress

In electrochemical cells, Coulombic efficiency refers to the ratio of the charge delivered during discharge to the amount stored during charging. CE is typically measured by the device that discharges and recharges the cell or half-cell under test in the lab.

Paul Scherrer Institute and Toyota RD team finds tiny memory effect in Li-ion batteries; implications for vehicle battery management systems

Green Car Congress

Up until now, Li-ion batteries have been considered to exhibit no “memory effect”—a deviation in the voltage of the battery resulting from repeated charging after being only partially discharged that can limit the usability of the stored energy as well as the ability to determine the state of charge of the battery reliably.
