A hybrid lithium-ion battery model for system-level analyses

Abstract

Summary We describe an advanced lithium‐ion battery model for system‐level analyses such as electric vehicle fleet simulation or distributed energy storage applications. The model combines an empirical multi‐parameter model and an artificial neural network with particular emphasis on thermal effects such as battery internal heating. The model is fast and can accurately describe constant current charging and discharging of a battery cell at a variety of ambient temperatures. Comparison to a commonly used linear kilowatt‐hour counter battery model indicates that a linear model overestimates the usable capacity of a battery at low temperatures. We highlight the importance of including internal heating in a battery model at low temperatures, as more capacity is available when internal heating is taken into account.

Lithium‐ionbatterySOC/SOHadaptive estimation via simplified single particle model

“…Also, PDEbased battery model parameter calibration is laborintensive and computationally expensive. [14][15][16][17][18][19] Finally, various lithium-ion battery health and work conditions make it difficult to find a general but high-accuracy model-based SOC/SOH estimation approach.…”

“…An energy storage is dedicated to cover high power demands and fast load fluctuations including transients. A second energy storage is considered as a high‐energy storage with low self‐discharge rate and lower energy specific installation cost …”

“…A second energy storage is considered as a high-energy storage with low selfdischarge rate and lower energy specific installation cost. 5 Several extant studies examined the modeling and simulation of ESS including its application. Examples include a theoretical and experimentally proven model for hybrid piezoelectric and energy harvester development, 6 development of a magnetic ESS, 7 and theoretical-simulation of temperature profiles in ESS system and development of various models for the thermal behavior of a system.…”

A graphical model for evaluating the status of series-connected lithium-ion battery pack

“…Researchers are proposing different kinds of strategies to model the behavior of battery pack, considering the balance of the accuracy and the computational loads. Lumped equivalent circuit model that takes the battery pack as a single cell has been built . The lumped model does not consider the cell variations, therefore unable to capture the full status of the battery pack.…”

“…Lumped equivalent circuit model that takes the battery pack as a single cell has been built. 23 The lumped model does not consider the cell variations, therefore unable to capture the full status of the battery pack. However, detailed modeling of the behavior of all the cells is a time-consuming process.…”
