2 General information about Lithium iron phosphate batteries Lithium iron phosphate (LiFePO4 or LFP) is the safest of the mainstream li-ion battery types. The nominal voltage of a LFP cell is 3,2V (lead-acid: 2V/cell). A 12,8V LFP battery therefore consists of 4 cells connected in series; and a 25,6V battery consists of 8 cells connected in series.
The hysteresis in the state-of-charge (SoC) vs. open-circuit voltage characteristic of a lithium-iron-phosphate (LiFePO 4, LFP) battery is modelled with two approaches.The first one is based on a first-order charge relaxation equation, the second one is the Preisach model implemented with the Everett function.
ABSTRACT This paper aims to develop an equivalent circuit model (ECM) for Lithium Iron Phosphate (LFP) batteries as they have a flat voltage profile and dominant hysteresis behavior compared to other lithium-ion chemistries. Hence, it is challenging to deduce an accurate model to predict the performance of the battery. The …
