Single-Particle Model for a Lithium-Ion Cell: Thermal Behavior

The model is used to predict the temperature and voltage profiles in a lithium-ion cell during galvanostatic operations. The single-particle thermal model is validated by comparing the simulated voltage and temperature profiles to the results obtained using a distributed porous electrode model.

Lithium-Ion Cell Charging and Discharging During Life Cycle

This is illustrated in Figure 1. Figure 1: Standard lithium-ion cell CCCV charging. In CCCV charging the cell is first charge by a constant current (CC) at a desired rate, followed by float charging with a constant voltage (CV), equal to the maximum recommended cell voltage.

BU-409: Charging Lithium-ion

The Li ion charger is a voltage-limiting device that has similarities to the lead acid system. The differences with Li-ion lie in a higher voltage per cell, tighter voltage tolerances and the absence of trickle or float charge at full charge.
