Design of Cylindrical Thermal Dummy Cell for Development of Lithium-Ion Battery Thermal Management System

This paper aims to design thermal dummy cells (TDCs) that can be used in the development of lithium-ion battery management systems. Based on physical property and geometry real 18,650 cylindrical cells, a three-dimensional model TDCs was designed, it is numerically simulate performance TDCs. Simulations show TDC mimic temperature change surface cell both at static dynamic current load. Experimental results rate heating resistance less than 0.43% for temperatures between 27.5 °C 90.5 °C. Powered by two-step voltage source 12 V, difference 1 1.6 along circumference axial directions, respectively. constant 6 rising rates core are higher 1.9 °C/min. Afterwards, proposed investigating its under New European Driving Cycle (NEDC), same tests were conducted using cells. The test indicates matches well with during NEDC test, while rise exceeds suburban cycle. demonstrates feasibility replace which greatly improve safety efficiency
