— Parameterization and Observability Analysis of Scalable Battery Clusters for Onboard Thermal Management — Thermal management is an important issue for lithium ion batteries, as overheating may result in disastrous consequences. Although the battery surface temperature is commonly measured, the core temperature of a cell may be much higher hence more(More)
—In this paper we model and experimentally verify the evolution of liquid water and nitrogen fronts along the length of the anode channel in a Proton Exchange Membrane Fuel Cell operating with a dead-ended anode that is fed by dry hydrogen. The accumulation of inert nitrogen and liquid water in the anode causes a voltage drop, which is recoverable by(More)
— Lithium ion batteries should always be prevented from overheating and, hence, thermal monitoring is indispensable. Since only the surface temperature of the battery can be measured, a thermal model is needed to estimate the core temperature of the battery, which can be higher and more critical. In this paper, an online parameter identification scheme is(More)
In this paper, for the first time, an equivalent circuit electrical model is integrated with a two-state thermal model to form an electro-thermal model for cylindrical lithium ion batteries. The parameterization of such model for an A123 26650 LiFePO 4 cylindrical battery is presented. The resistances and capaci-tances of the equivalent circuit model are(More)
— Temperature monitoring is a critical issue for lithium ion batteries. Since only the surface temperature of the battery can be measured, a thermal model is needed to estimate the core temperature, which can be higher and hence more critical. In this paper, an on-line parameter identification scheme is designed for a cylindrical lithium ion battery thermal(More)
Enforcement of constraints on the maximum deliverable power is essential to protect lithium-ion batteries from over-charge/discharge and overheating. This paper develops an algorithm to address the often overlooked temperature constraint in determining the power capability of battery systems. A prior knowledge of power capability provides dynamic(More)
—A new education program is under development at the University of Michigan to educate engineers in the fundamentals of electrochemical propulsion systems for vehicle electrification. This paper describes two courses that are part of this larger program: " Battery Systems & Control " and " Fuel Cell Vehicles & Hydrogen Infrastructure. " These courses seek(More)
