拆解刚收到的Powergenix镍锌NiZn电池充电器
拆解刚收到的Powergenix镍锌NiZn电池充电器镍锌电池第一次听说是在手电论坛,感觉挺新鲜的,搜了网络,在Amazon发现有货,并且还在做特价,
4节镍锌电池+专用充电器特价$12.99,同时8节镍锌充电电池特价$13.99,不算贵就同时买回来玩玩
套装,包装正面

拆出来了

充电器做工不错,塑料件很赢实
http://www.canadasky.com/images/stories/charger/powergenix-NiZn-charger/powergenix-NiZn-charger-06.jpg
商标印刷很清晰两个指示灯,左边红色,右边绿色
http://www.canadasky.com/images/stories/charger/powergenix-NiZn-charger/powergenix-NiZn-charger-07.jpg
支持4AA电池或2AAA电池
http://www.canadasky.com/images/stories/charger/powergenix-NiZn-charger/powergenix-NiZn-charger-08.jpg
正极附近,下面都有铁片,可能是温度检测用的
http://www.canadasky.com/images/stories/charger/powergenix-NiZn-charger/powergenix-NiZn-charger-09.jpg
负极的金属件弹性十足,铁皮比较厚
http://www.canadasky.com/images/stories/charger/powergenix-NiZn-charger/powergenix-NiZn-charger-10.jpg
背面,插头有部分突起,似乎不是特别好,放在插座上会不会放不稳呢
http://www.canadasky.com/images/stories/charger/powergenix-NiZn-charger/powergenix-NiZn-charger-11.jpg
标牌,四节同时充电电流不算小,750mA,大约两小时多充满,后盖固定螺丝是普通的,标签纸下面还有一颗
http://www.canadasky.com/images/stories/charger/powergenix-NiZn-charger/powergenix-NiZn-charger-12.jpg
两颗螺丝取下来,后盖就可以打开,但打开过程中费了点劲,上下盖,是咬合,很紧密,塑料件很结实
背面线路,密密麻麻的贴片元件
http://www.canadasky.com/images/stories/charger/powergenix-NiZn-charger/powergenix-NiZn-charger-13.jpg
电源插头部分还有两个螺丝固定
http://www.canadasky.com/images/stories/charger/powergenix-NiZn-charger/powergenix-NiZn-charger-14.jpg
电源部分,背面,发现做工不是很精细,有元件的引脚很长没有剪短
http://www.canadasky.com/images/stories/charger/powergenix-NiZn-charger/powergenix-NiZn-charger-15.jpg
侧面看,还挺长的
http://www.canadasky.com/images/stories/charger/powergenix-NiZn-charger/powergenix-NiZn-charger-16.jpg
加强对比,看清楚了,好长啊

三星的控制芯片3F84K4XZZSK94, Samsung 8-bit MCU,单片机

9926A芯片,Dual N-Channel 2.5V Specified PowerTrench MOSFET场效应管
http://www.canadasky.com/images/stories/charger/powergenix-NiZn-charger/powergenix-NiZn-charger-19.jpg
LM324DR 运算放大器
http://www.canadasky.com/images/stories/charger/powergenix-NiZn-charger/powergenix-NiZn-charger-20.jpg
看到了负极串联的大功率小电阻
http://www.canadasky.com/images/stories/charger/powergenix-NiZn-charger/powergenix-NiZn-charger-21.jpg
另外一颗场效应管
http://www.canadasky.com/images/stories/charger/powergenix-NiZn-charger/powergenix-NiZn-charger-22.jpg
电路板正面,上部是开关电源,下半部就很简洁了,PCB板生产日期,应该是09年,还是10年呢
http://www.canadasky.com/images/stories/charger/powergenix-NiZn-charger/powergenix-NiZn-charger-23.jpg
正极附近的贴片,果然是用来检测温度的
http://www.canadasky.com/images/stories/charger/powergenix-NiZn-charger/powergenix-NiZn-charger-24.jpg
上面还沾有小许的导热硅脂
http://www.canadasky.com/images/stories/charger/powergenix-NiZn-charger/powergenix-NiZn-charger-25.jpg
热敏电阻上也有导热硅脂
http://www.canadasky.com/images/stories/charger/powergenix-NiZn-charger/powergenix-NiZn-charger-26.jpg
开关电源用料还算规矩,次级用了较厚大的散热铝片
http://www.canadasky.com/images/stories/charger/powergenix-NiZn-charger/powergenix-NiZn-charger-27.jpg
次级整流二极管,滤波电容
http://www.canadasky.com/images/stories/charger/powergenix-NiZn-charger/powergenix-NiZn-charger-28.jpg
电源管理芯片 TNY177PN
http://www.canadasky.com/images/stories/charger/powergenix-NiZn-charger/powergenix-NiZn-charger-29.jpg
高频变压器看上去,做工很一般啊
http://www.canadasky.com/images/stories/charger/powergenix-NiZn-charger/powergenix-NiZn-charger-30.jpg
正面的一些印刷,和跳线
http://www.canadasky.com/images/stories/charger/powergenix-NiZn-charger/powergenix-NiZn-charger-31.jpg
http://www.canadasky.com/images/stories/charger/powergenix-NiZn-charger/powergenix-NiZn-charger-32.jpg
来看看套装里的电池,外包装还挺紧密的
http://www.canadasky.com/images/stories/charger/powergenix-NiZn-charger/powergenix-NiZn-charger-33.jpg
正极,白色挡板,感觉像是某种纸
http://www.canadasky.com/images/stories/charger/powergenix-NiZn-charger/powergenix-NiZn-charger-34.jpg
负极,有圆形突起,似乎被磨损很厉害,猜测制作过程中,电池是立起来移动的,传送过程摩擦挺厉害的
http://www.canadasky.com/images/stories/charger/powergenix-NiZn-charger/powergenix-NiZn-charger-35.jpg
四节电池电压并不一致
http://www.canadasky.com/images/stories/charger/powergenix-NiZn-charger/powergenix-NiZn-charger-36.jpg
http://www.canadasky.com/images/stories/charger/powergenix-NiZn-charger/powergenix-NiZn-charger-37.jpg
http://www.canadasky.com/images/stories/charger/powergenix-NiZn-charger/powergenix-NiZn-charger-38.jpg
http://www.canadasky.com/images/stories/charger/powergenix-NiZn-charger/powergenix-NiZn-charger-39.jpg
1.3299V
1.3994V
1.2893V
1.3702V
按照标称1.6V算的话,这种电压,基本上就是没电的,难怪说明书上说使用前要进行充电,似乎并不是低自放电池
后续的电池测试将在未来的几天中进行

{:1_238:} CX能上亚马逊购物…… 昨天在数码之家拜读过了,呵呵 很多红叉啊。 刷新一下,看到图片了。内部不错嘛。 眼馋那块表 昨天已拜读......
看到亚马逊和淘宝的价格比较.我只想问候擎天柱他们祖宗几十代,太阳! 好长的元件的引脚 貌似充电器比和尚的好很多?
召唤和尚上裸图...... 咋刷新都看不见图的飘过,郁闷!!!!!!!!!!!!!! 刷了N次新还是没看到图啊. 这个快冲套装不错,建议论坛商家搞一批进行团购...... 和尚测了10多次容量。。。。 全部红XX 想看个图就那么难? 挂了????
