Abstract
Lithium-ion batteries have been used for an extensive range of quite demanding applications, and are supplied in a large variety of shapes and sizes by many manufacturers around the world. The electro-thermal-chemical characterization of the batteries electro-chemical cells is receiving attention, but the variety of these cells is such that frequently the end users need to make some characterization themselves. The most usual and standardized approach is to make controlled cell charges and discharges in an environment of more or less controlled temperature, without control of the heat released and absorbed by the cell along these processes. Another pretty common approach is to use an adiabatic calorimeter to measure the heat released by the battery, without temperature control. This work presents initial results of an effort to develop a very low cost Arduino based equipment to control a prismatic cell surface temperature, with the future intention of monitoring the heat it releases, using Peltier modules. The influence of the ambient temperature was minimized using expanded polystyrene plates. The use of a heat conduction analytical solution in thermophysical properties estimation employing the equipment here presented is exemplified. The already performed experiments revealed some cautions to be exerted in the use of such low cost equipment: a temperature set-point below the environment dew point caused some trouble, the electromagnetic noise produced by switched power supplies was really detrimental to temperature measurements performed using analog sensors. In spite of these difficulties, these tests indicated that the temperature control by low cost Peltier modules can be very effective and practical in prismatic Li-ion cells characterization experiments.
