This paper investigates power management algorithms that optimally manage lithium-ion battery pack health, in terms of anode-side film growth, for plug-in hybrid electric vehicles (PHEVs). Specifically, we integrate a reduced electrochemical model of solid electrolyte interface (SEI) film formation into a stochastic dynamic programming formulation of the PHEV power management problem. This make...

Battery pack specific energy, which can be enhanced by minimising the mass of battery thermal management system (BTMS), is a limit on electric fixed-wing flight applications. In this paper, use phase-change materials (PCMs) for BTMSs numerically explored in 3D domain, including an equivalent circuit model. A parametric study PCM properties effective conducted typical one-hour flight. PCMs maint...

Fast capacity estimation for retired batteries is necessary when are recycled echelon utilization. Here, a fast method proposed LiFePO4 battery. First, full survey of battery pack and cells degradation after long period service studied. Then the filtered ICA used to study variation phenomenon batteries, relationship between IC curve feature remaining was Finally, using incremental Gaussian proc...

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. In addition effectively monitoring all electrical parameters pack system, such as voltage, current, temperature, BMS also used improve performance with proper safety measu...
