Bateria-multzoen simulazio elektrotermikoak: 14S5P bateria-multzo komertziala

2019 
EnglishElectrothermal behaviour of 14S5P battery-pack, usually placed in small electric vehicles, is analysed for the first time using multiphysics simulations. An electrochemical model is developed to describe the electric behaviour of LMO 26650 battery (3.5 Ah). NMC active material is added in the LMO cathode (0, 29, and 59 % wt) to check the improvement of the electrical performance of the battery. The heating process of LMO 26650 battery is simulated in a high intensity discharge process (10 A). As a result, the temperature of the cell suffers an important increment of 64 %. Finally, with intensities of usual working conditions, the temperature of 14S5P battery-pack does not increase remarkably. EuskaraNormalean ibilgailu elektriko txikietan erabiltzen den 14S5P bateria-multzoaren jokaera elektrotermikoa lehenengo aldiz aztertu dugu simulazio multifisikoen bidez. LMO kimikako 26650 bateriaren (3,5 Ah) jokaera elektrikoa simulatzeko eredu elektrokimikoa garatu dugu. LMOko katodoan NMC material aktiboa gehitu dugu (pisuan, % 0, % 29 eta % 59), bateriaren ezaugarri elektrikoak hobetzen direla egiaztatzeko. LMO kimikadun 26650 bateriaren beroketa simulatu dugu intentsitate altuko deskarga batean (10 A), eta tenperatura % 64 igotzen dela behatu dugu. Azkenik, ohiko lan-baldintzetako korronteetan, 14S5P bateria-multzoaren tenperatura ez dela era nabarmenean handitzen frogatu dugu.
