Abstract
Intergrating the application of the battery group in the electric vehicle(EV),the relation of Li-ion battery characteristics and temperature,the way of the battery pack heating and cooling methods were discussed.Thermal simulation and actual measurement were utilized,when 100 Ah battery pack (LP2770134,6 modules composited by 11 series with 5 parallels,2 modules composited by 7 series with 5 parallels and 2 modules composited by 8 series with 5 parallels) was at different discharge rates,different ambient temperatures.Along with the ambient temperature increasing,the temperature of the battery pack was risen at the same discharge rate;when the ambient temperature increased,the cells temperature difference increased and some of the cell temperature exceeded operating temperature(when the ambient temperature was d0 ℃,the maximum cell temperature reached 51.5 ℃).关键词
