Accelerated lifetime testing in small SOC intervals on commercial pouch cells; challenges and countermeasures
Paper in proceedings, 2017
A methodology for lifetime testing of lithium-ion batteries in small SOC intervals is presented. The specific test procedure and level of control is important in producing reliable data. The methodology offers high precision without increasing the test duration. The duration time can be reduced with up to 50%, by ensuring more continuous cycling and by reducing the number of performance tests.
