This paper deals with a method to detect the existence of an over-discharged cell in lithium-ion battery (LIB) pack by measuring total harmonic distortion (THD) rate voltage response. Over-discharge LIB reduces available capacity irreversible chemical reactions, resulting serious safety risks such as explosions. Even if only one exists pack, it accelerates decomposition other cells. In general,...

Plug-in hybrid electric vehicle (PHEV) technology has the potential to help address economic, environmental, and national security concerns in the United States by reducing operating cost, greenhouse gas (GHG) emissions and petroleum consumption from the transportation sector. However, the net effects of PHEVs depend critically on vehicle design, battery technology, and charging frequency. To e...

The battery pack performance and expected lifespan are crucial in electric vehicle applications. Balancing the charge on a connected series parallel is due to manufacturing discrepancies distinct of each cell standard pack. In this paper, switched-resistor passive balancing-based method proposed for balancing cells management system (BMS). value available voltage at terminals balanced using res...

Abstract The battery management system (BMS) is the main safeguard of a for electric propulsion and machine electrification. It tasked to ensure reliable safe operation cells connected provide high currents at voltage levels.

Prognostics and remaining useful life (RUL) estimation for lithium-ion batteries play an important role in intelligent battery management systems (BMS). The capacity is often used as the fade indicator for estimating the remaining cycle life of a lithium-ion battery. For spacecraft requiring high reliability and long lifetime, in-orbit RUL estimation and reliability verification on ground shoul...

Battery packs containing multiple cells in series require a balancing system in order to ensure energy and power requirements for the battery pack are maintained throughout its life. Based on the equivalent circuit model (ECM) of a cell, a new framework is proposed which can accommodate a controloriented model of a balancing system while maintaining the same measured input and output as an ECM....

This work is focused on the state of charge (SOC) estimation of a lithium-ion battery based on a nonlinear observer. First, the second-order resistor-capacitor (RC) model of the battery pack is introduced by utilizing the physical behavior of the battery. Then, for the nonlinear function of the RC model, a one-sided Lipschitz condition is proposed to ensure that the nonlinear function can play ...
