Learn MoreHowever, due to the large latent heat of PCM, the temperature of the initial stage of the battery increased slowly in a cold environment. Additionally, the larger thermal mass of the PCM prevented the cell from self-heating during long-term application in low temperatures, resulting in a loss of power and capacity.
In general, from the perspective of cell design, the methods of improving the low-temperature properties of LIBs include battery structure optimization, electrode optimization, electrolyte material optimization, etc. These can increase the reaction kinetics and the upper limit of the working capacity of cells.
Subsequently, a model for managing the thermal conditions of the battery was created, and a resilient Nonlinear Model Predictive Control (NMPC) approach relying on Neural Networks (NN) was suggested to regulate the battery's temperature. This approach could attain superior control precision in the presence of disturbances.
