Abstract
- For revealing the low-temperature performance of lithium-ion battery, an experimental study on the charge-discharge characteristics of a 35A . h lithium manganate battery cell is conducted under low temperature, and the consistency of battery is analyzed by voltage range. The results indicate that at low temperature, the charge-discharge performances of battery drop substantially (under -l0°t , the battery can only be charged to 60. 23% of its rated capacity at 10A; and under -40°t , only 22% of rated capacity can be discharged) , the charging and discharging internal resistances significantly increase and the consistency of battery deteriorates. So it is strongly recommended to use heating devise in lithium-ion battery pack for assuring the normal operation of electric vehicles at low temperature. [ABSTRACT FROM AUTHOR]
