Multi Temperature Li-ion Battery Data - SB LiMotive 5Ah

A new 5.2Ah SBLimotive li-ion battery cell was tested in an 8 cu.ft. thermal chamber. A 75amp, 5 volt Digatron Firing Circuits Universal Battery Tester channel with a voltage and current accuracy of 0.1% of full scale was used to perform the testing. A series of tests were performed at six different temperatures, and the battery was charged after each test at 1C rate to 4.2V, 10mA cut off charge current, at battery temperature of 25degC. Tests include characterization tests (HPPC, constant current discharges, etc) and a series of electric vehicle drive cycle power profiles.本研究针对一款5.2安时的SBLimotive锂离子电池电芯开展测试，试验在容积为8立方英尺的热试验箱中进行。测试采用一台75安、5伏的Digatron Firing Circuits通用电池测试仪通道，该设备的电压与电流测量精度为满量程的0.1%。本次试验设置了六种不同温度工况，每次测试完成后，均在电池温度维持25摄氏度的条件下，以1C倍率将电芯充电至4.2V，充电截止电流为10mA。测试内容包括特性表征测试（HPPC、恒流放电等）以及一系列电动汽车行驶循环功率曲线测试。
