Abstract

It is important to study the heat production characteristics of large capacity energy storage lithium-ion battery cells for the design of thermal management of lithium-ion battery energy storage. The thermal conductivity and specific heat of the cell and the adiabatic temperature characteristics of the cell during charging and discharging were measured by experimental method. A heat transfer model considering the heat conduction inside the cell and the natural convection heat transfer between the surface of the cell and the ambient was presented. The maximum temperature and the maximum temperature rise of the cell during charging and discharging were obtained by numerical simulations. The variation of the surface temperature of the cell with time and the optimum-ion distance between the cells were obtained. At the same time, the variation trends of the cooling air quantity changing with the inlet air temperature were obtained. The results show that the heat production of lithium-ion battery with large capacity during charging is slightly higher than that during discharging.
