Battery pack configuration design. The assumption of uniform heat generation is a common simplification method in the study of thermal management of lithium-ion batteries. Many studies have also adopted similar simplified assumptions when conducting thermal management analysis.
Validation with a lithium-ion battery pack case study demonstrates the method’s effectiveness, providing valuable knowledge for future cell and pack designs that employ different battery cell arrangements and diverse cooling strategies.
A multi-domain model-based methodology is proposed to support the design of new battery packs. Electro-thermal models of Li-NMC storage cells have been investigated and validated by means of laboratory testing campaigns. Thermal effects of forced air Battery Thermal Management Systems have been evaluated.
The fire propagation behavior of lithium-ion battery warehouse was studied. The SOC value of stored lithium-ion batteries should be as small as possible. When storing 70%–100% SOC batteries, a quick-response sprinkler shall be set. To prevent the spread of fire, a critical value of shelf spacing is defined.
Conclusions This study developed a model-based methodology for use in the design of battery packs for automotive applications. This methodology is based on a multi-domain simulation approach to allow electric, thermal and geometric evaluations of different battery pack configurations, with particular reference to Li-NMC technology.
Lithium-ion batteries (LIBs) have shown considerable promise as an energy storage system due to their high conversion efficiency, size options (from coin cell to grid storage), and free of gaseous exhaust.
