4 c2 t0 r q6 X! e8 D# m2 P最近在看IEC62133-2012,但是你们很多东西都不明白,请高手指教一下, ( s0 K5 k( K4 } |( G4 r, P如:The test shall becarried out in an ambient temperature of +20℃ ± 5℃. Each test battery shall be discharged at aconstant current of 0.2 It A, to a final discharge voltage specified bythe manufacturer. Sample batteries shall then be charged at a constant currentof 2.0 It A, usinga supply voltage (not to exceed the maximum voltage supplied by the recommendedcharger - if value not available it shall be 5,0 V per cell) sufficient tomaintain this current of 2.0 It A throughout the duration of the test or untilthe supply voltage is reached. A thermocouple shall be attached to each testbattery. For battery packs, the temperature shall be measured on the batterypack casing. The test shall be continued until the temperature of the outer casingreaches steady state conditions (less than10℃ change in 30-minute period) or returns toambient.* T6 d) y1 i! P7 R1 T$ }
这短话中出现的 It A到底该如何理解 8 `7 U G) |# G. {; s! C作者: novice-safty 时间: 2013-7-29 19:03
这里的It A应该就是等于1C放电的电流。作者: novice-safty 时间: 2013-7-29 19:05
电池的应该是IEC62133。楼主是不是写错了?作者: yangcanluck 时间: 2013-8-7 09:02
