Lumped-parameter system

A lumped-parameter system is a simplified model of a dynamic system where the system''s properties are assumed to be concentrated at discrete points or nodes, rather than being distributed over a spatial domain. This approach allows for easier analysis and understanding of the system''s behavior by treating variables like mass, energy, and charge as concentrated at

Lumped Capacitance Thermal Modelling Approaches for Different

In the analytic approach to the lumped capacitance model, a focus is placed on rapidly determining the thermal behavior of battery cells. It has been established that during charging and discharging at various C-rates, the heat generated in the battery cells arises predominantly from Joule''s heating loss, entropic phenomena, and polarization effects [17, 18],
