VHDL-AMS electro-thermal modeling of a lithium-ion battery

Li-ion rechargeable batteries present an useful energy, low battery effect, and slow Self-discharge loss of charge when not in use. In this paper, we describe a VHDL-AMS model describing coupled electrical and thermal behaviors of a Li-Ion cell. This model relies on the experimental extraction of real characteristic parameters by using an efficient and low-cost test bench. Therefore, it allows to predict the realistic voltage variations by taking into account the state of charge and heating of the Li-ion cell, in order to design a battery system according the required capacity and electric power for the current electrical applications.
