Abstract

High power lithium iron phosphate (LFP) batteries suitable for Electric Vehicles are tested in this work. An extended cycle-life testing is carried out, consisting in various types of experiments: standard cycling, optimized fast charge with high constant current discharge (4 C) and simulating driving dynamic stress protocols (DST). The fast charge/DST discharge tests are carried out with depth of discharge (DOD) dependency (100% DOD and partial 50% DOD discharge). A complete analysis of the cycling results is developed, showing an overall good performance of the tested batteries. In all of experiments, long term U.S. Advanced Battery Consortium goals are met: fast charging, cycle life and specific energy. Only the long term specific energy goal is not achieved, which is a drawback intrinsic in this technology. The results provide useful information for battery selection, BMS designs and other applications in EV industry.
