NÁVRH METOD PRO DIAGNOSTIKU DIFÚZNÍHO PROCESU LI-ION BATERIE
Original language description
In today's applications, batteries, in the role of electricity storage, have a significant and irreplaceable place. Lithium-ion (Li-ion) batteries have become the most popular technology. When using them, great importance is placed on safety and therefore it is necessary to monitor their condition. Since it is a complex electrochemical system and it is practically possible to measure only their electrical quantities and temperature, their diagnostics becomes a challenging task. With regard to the internal process of lithium ion diffusion, new diagnostic methods using short current pulses to detect a change in the diffusion process, which changes with the age of the battery, are presented. Two methods will be presented here, which seem to be very promising for the analysis of the diffusion process. The first results show positive conclusions.
