What is battery pack SoC?
In Ref. , Zhang et al. also presented the definition of battery pack SOC by analyzing the energy efficiency affected by inconsistent characteristics of battery cell, and developed an EKF-UKF based duel filter to online estimate the pack SOC.
How is a battery pack SoC analyzed?
The battery pack SOC is analyzed through considering the effect of passive balance control. A normalized OCV model is developed to describe the temperature-dependent OCV characteristic for all in-pack cells by uniform algebraic expression for simplifying the structure of battery pack model. 2.3.1.
How is battery pack model based on a normalized OCV model?
Based on experimental results, a normalized OCV model was developed and applied in the Thevenin model for the modeling of cell. Then, the battery pack model was established by connecting cell models in series.
What is a battery pack connected to a DMM to measure OCV?
Battery pack connected directly to a DMM to measure OCV. (d) Equivalent circuit to (c). At the pack or module level, the output voltages and currents are much larger than at the cell level.
What are lithium-ion battery packs?
Lithium-Ion battery packs are an essential component for electric vehicles (EVs). These packs are configured from hundreds of series and parallel connected cells to provide the necessary power and energy for the vehicle. An accurate, adaptable battery management system (BMS) is essential to monitor and control such a large number of cells.
Does cell inconsistency affect battery pack SoC estimation?
Robust estimation of the state of charge (SOC) is crucial for providing the driver with an accurate indication of the remaining range. This paper presents the state of art of battery pack SOC estimation methods along with the impact of cell inconsistency on pack performance and SOC estimation.
