【摘要】 为满足15～1 000 ms的50～80T脉冲磁场的供电参数要求,对6GFM-200阀控式铅酸蓄电池组分别进行了不同负载下高倍率充/放电性能、高倍率充/放电循环、高倍率放电状态下蓄电池内阻等测试。实验结果证明:蓄电池在4 000次2 000 A/1.5 s的高倍率充/放电循环过程中,尽管蓄电池内阻随着剩余容量衰减而增大,但蓄电池工作电压始终保持在12.87～13.80 V之间,蓄电池没有发生发热、膨胀、失效的现象。更多还原

【Abstract】 To meet the power supply requirements of the 15～1 000 ms 50～80T pulsed magnet field,a series of tests were proceeded on the 6GFM-200 valve-regulated batteries,including the high rate charge/discharge performance test under different loads,high rate charge/discharge cycle test and the internal resistance test under the condition of discharging at different high rate.During the 4000 cycles at 2000A/1.5s charging-discharging rate,the voltages kept stably between 12.87 V and 13.8 V,though the internal resistance of the battery increased with the decreasing of the residual capacity.It was not observed that the batteries were heat,expanded or failure during the tests.更多还原
