Abstract: 

A new nonlinear model for electrical analysis of Ni-Cd batteries is proposed. Model parameters are considered to be linear and nonlinear functions of charge current. To generate these parameters, battery characteristics of different charge currents are measured and used. Linear dependency of parameters are generated using two charge rates while nonlinear variations are modeled based on three charge currents. Thermal characteristics are computed with results obtained by a finite element based code, ANSYS, and a generated finite difference (lumped parameter) model. For experimental analysis a laboratory setup capable of measuring electrical and thermal behaviour of Ni-Cd batteries at different charge rates is used. The Computed and measured results show good agreements for a 7 Ah, size F, Ni- i Cd battery, manufactured by SANYO.
