| Abstract: | To analyze the thermal behavior of the cylinder Ni/MH battery during overcharging,a two-dimensional thermal model is provided in this work.More reliable data is provided to create the precise thermal model.The amount of heat of the battery during overcharging at different currents was measured using quartz frequency microcalorimeter.To obtain the heat transfer coefficient of the battery during overcharging,the heat dissipation rate was fitted into linear functions and three different exponential functions f... |
