Modeling for Lithium Iron Phosphate Battery and its Simulation in PSCAD

Abstract:

This paper proposes an improved dynamic model of lithium iron phosphate battery, and shows the simulation results. The method takes into account the nonlinear characteristics of the battery charging and discharging, and changes the variation of battery resistance into that of voltage, which makes the simulation circuit simpler and easier to be implemented. Simulations examine the time-changing characteristics of the state of charge (SOC), depth of discharge and the current/voltage in the charge/discharge processes, as well as the relationship between voltage and SOC. The model has correctively shown the dynamic characteristics of lithium iron phosphate battery in our simulations.
