Abstract
The rate and shape of the charging current indubitably affect the charging time and the ageing rate of a battery. Depending on the application requirements, it is possible to use high-charging current in order to decrease the charging time. However, the influence of fast-charging current profiles should be investigated to identify their impact on battery functionality over time. In this article, static and dynamic fast-charging current profiles are applied to a high power 7 Ah LiFePO4-based cells (LFP), and the results of cycle-life and characterization tests are discussed. To select the proper fast-charging profile, the evaluation relies on some factors: discharge capacity retention, charging capacity, charging time, and cell temperature. After 1700 cycles, the results revealed that the dynamic fast-charging current profile has a prominent role in decreasing the degradation rate as well as the charging time of cells compared with the static fast-charging profile.
