PTC Self-heating Experiments and Thermal Modeling of Lithium-ion Battery Pack in Electric Vehicles

This paper proposes a positive temperature coefficient (PTC) self-heating method, in which EVs can be operated independently of external power source at low temperature, with a lithium-ion battery (LIB) pack discharging electricity to provide PTC material with power. Three comparative heating experiments have been carried out respectively. With charge/discharge tests implemented, results demons...

Improved nanofluid cooling of cylindrical lithium ion battery pack in charge/discharge operation using wavy/stair channels and copper sheath

Abstract: In order to improve the thermal management system for cooling an electric vehicle battery pack, the thermal performance of the battery pack in two states of charge and discharge in different working conditions by using a copper sheath around the batteries and a copper sheath, as well as a stair channel on top of the battery pack and using of nanofluid as cooling fluid, has been studie...

Estimation of Lithium-ion Concentrations in Both Electrodes of a Lithium-ion Battery Cell

For control and estimation tasks in battery management systems, the benchmark Li-ion cell electrochemical pseudotwo-dimensional (P2D) model is often reduced to the Single Particle Model (SPM). The original SPM consists of two electrodes approximated as spherical particles with spatially distributed Li-ion concentration. However, the Li-ion concentration states in these two-electrode models are ...
