Rezumat: Aceasta lucrare prezinta o analiza a comportamentului termic a unei baterii litium ion-polimer, baterie ce este mai des utilizata in domeniul auto datorita densitatii sale ridicate de energie precum si a densitatii de putere. Comportamentul termic al bateriei consta in descrierea distributiei temperaturii utilizand diverse configuratii ale termocuplurilor si o analiza termografica. A fost demonstrat ca utilizand diverse configuratii ale termocuplurilor se poate obtine distributia temperaturii pe suprafata bateriei, precum si influentele temperaturii asupra performantei bateriei.

Abstract: This paper presents a thermal behavior analysis of a Li-ion polymer battery that is more often used in automotive domain due to its high energy and power density. The thermal behavior of battery consists in describing the temperature distribution using different configuration of thermocouples and a thermographic analysis. It was shown that using different configuration of thermocouples reveals the distribution of battery temperature and the influence which this may have on its performance

Keywords: thermal behavior, Li-Ion polymer, temperature distribution
