Affection Mode of Temperature on the Lithium-ion battery performance Used in Electric Vehicle

摘要

Temperature is the most important external impact factor on the performance of lithium-ion battery used in electric vehicle. The affection mode and internal mechanism of temperature on the capacity and internal resistance is analyzed qualitatively based on the accelerated life testing results. And the issue related to the implementation of the battery life evaluation is also discussed. The testing samples for this study are two types of high power lithium-ion battery with 8 Ah rate capacity, including Manganese oxide lithium-ion battery and Phosphate iron lithium-ion battery.
