The paper deals with the cooling of batteries. The first step was the thermal\udcharacterization of a single cell of the module, which consists in the detection of the thermal\udfield by means of thermographic tests during electric charging and discharging. The purpose\udwas to identify possible critical hot points and to evaluate the cooling demand during the\udnormal operation of an electric car.\udAfter that, a study on the optimal configuration to obtain the flattening of the temperature\udprofile and to avoid hot points was executed. An experimental plant for cooling capacity\udevaluation of the batteries, using air as cooling fluid, was realized in our laboratory in ENEA\udCasaccia. The plant is designed to allow testing at different flow rate and temperatures of the\udcooling air, useful for the assessment of operative thermal limits in different working\udconditions. Another experimental facility was built to evaluate the thermal behaviour changes\udwith water as cooling fluid. Experimental tests were carried out on the LiFePO4 batteries, under\uddifferent electric working conditions using the two loops.\udIn the future, different type of batteries will be tested and the influence of various parameters\udon the heat transfer will be assessed for possible optimal operative solutions
