Charger Soshine SC-S7
(Soshne SC-S7 充电器)
Review of Charger Soshine SC-S7 UKCharger Soshine SC-S7
收到一个英规的Soshine充电器 型号SC-S7
This is a smart charger that can handle both LiIon and NiMH batteries, it can
charge one battery at a time and is rated for a 1A charge current.
这是个只能的充电器，可以充锂电和镍氢电池，一次能充一直，充电电流是1A
I did not get the charger in a full retail package, but instead in a envelope.
我没有拿到包装，只是用个小包装好的。
The envelope contained the charger, a universal voltage (100-240V 50/60Hz) mains
power supply and a usb cable.
小包里包括，充电器，一个世界电压的适配器，和一个USB连接线
The plus connection is slightly raised, this means that the charger can be used
with flat top batteries.
正极有点突起，意味着可以充平头电池
The minus connection is a slider that can be manually moved . This gives a span
from 26 mm to 70 mm long batteries.
I would have liked a spring in one of the ends, this would have made the
adjustment easier.
The negative end can be used as a spring, but then it must be moved in, before
the battery is placed in the charger.
负极是个可以手动移滑动的按键，拉伸的长度很长，可以充从26毫米到70毫米的电池
我喜欢带个弹簧的五金，这种容易改变长度。
负极一段跟五金比较相似，但是不同的电池放进去后，要自己移动调节大小
Power can be supplied from a 12 vold adapter or from a usb power supply, in both
cases it requires a 1A power supply.
供电选择，可以是一个12V的适配器，也可以用USB供电，两种都最好是1A的电流
Instead of the typical red/green leds, this charger uses a display to show
status information on.
不像是其他的充电器的红绿指示灯，这个充电器是用液晶显示充电状态。
When no battery is in the charger it shows this standby display. There is a
faint clicking sound from the charger in this mode.
没有电池时，显示，STANDBY,这个模式有个轻微的咔哒声音。
While charging it shows the voltage and the time used, with LiIon it will also
show an estimate of how many percent capacity is charged into the battery.
The voltmeter has some limitations, for LiIon it will not show below 3.3 volt or
above 4.2 volt, it will stay at these voltages.
当充电时，显示电压，时间，锂离子会显示充电百分比，充电的电压显示范围3.3-4.2V
When done the display will show a battery full message, then show the time used
and the capacity charged into the battery, these 3 displays will cycle. The
capacity is not a precision measurement, but good enough to compare LiIon
batteries and see when it is time to replace a battery (Remember the battery
must be empty to measure the capacity).
For NiMH the value will be way above the battery capacity, these batteries need
some extra current when being charged.
当充满电时候，液晶显示器会会全部显示，充电用的时间，充电的容量，这两个指示交替显示
容量虽然不能仪器精确的测量，但是已经很好，足够区别不同容量的锂离子电池。还会告诉你什么
时候要换个新电池了。（记住测量容量时，电池要放完电）
对镍氢电池来说，也能测试一下容量，这些电池也要用特别的充电方法。
The charger can handle 70 mm long batteries including flat top cells.
充电器可以拉伸70毫米长
Measurements
测试
Below 0.7 volt the charger reports standby and is pulsing 130mA current to test
for a battery, this will also reset a protected battery。
电池低于0.7V，充电器显示STANDBY,这时的充电电流时130mA,来测试电池，这个状态也会重启，
这样就能保护电池
Between 0.7 volt and 2.3 volt the charger assumes it is a NiMH battery.
Above 2.3 volt the charger will assume LiIon.
在0.7V和2.3V时候，充电器计算出，这是个是镍氢电池，大于2.3V是充电器会认为是锂电池
When a battery is put into the charger it will start with about 300mA and after
some time switch to full charge current.
电池放到充电器里面，开始的电流是300毫安，过了一段时间，开始满电流充电
When charger is disconnected from power, but with a battery in, it will
discharge with 2 mA from a NiMH and 7mA from a LiIon.
拿开适配器，电池还放在充电器里，电池会放电，镍氢电池的电流时2mA，锂电是7mA
When the charge current goes below the termination current the charging is
stopped and it will discharge with 2 mA from a NiMH and 10mA from a LiIon, but
due to pulsing the battery will stay charged.
当充电电流达到截止时候，充电器会停止充电，这个时侯，镍氢和锂电电的放电电流时2mA和7mA
这个时候，充电器会给个脉冲小电流继续充电。
The charge will always restart charging when a battery is put into it or after a
power loss and for NiMH it might charge a significant amount of current.
充电器如果断开电源，充电器会重新启动，继续充电，，镍氢电池的话就会有个大电流充电
The first test is with a 18650 battery, the charger does a CC/CV charge profile,
but when it report battery full (At the yellow line) it starts doing some very
strange pulses.
第一次测试的是18650电池，充电的方法是恒流恒压充电，当液晶显示充电完成的时候，依然有电流在充电
Same battery, this time with usb power. The charger starts at full current, but
reduces the current during charge, maybe because it cannot supply full current
with the lower voltage difference between battery and usb voltage?
It does look like the pulses stops after some time. The pulses will not damage
the battery, but the battery will be charged slightly higher.
相同的电池，这次用USB连接线充电，开始时是很大的电流，不过一会电流就有减少，也许是
因为提供的电流不够，不能支持大电流充电，过了一段时间，看起来就像脉冲停止。脉冲不会损害
电池，但是电池就会充的稍微有点高
A smaller LiIon battery works exactly like the 18650 I tried first.
用小的电池充电跟用18650充电是一样的。
My old IMR cell, did not work as expected, after a short time the "Poor cell"
text turned on and it showed "FAIL" on the display. The charger has a point
about the cell.
I have also seen the charger only show "Poor cell", but continue to charge.
我的旧的IMR电池，原来就不能用了，放到这个充电器里充电，不出所料，过了一段时间，会显示
“Poor cell" 就是差的电池，然后显示“FAIL" 错误，充电器能够识别差的电池和坏的电池
When charging NiMH the 300mA current on for much longer time, than when charging
LiIon and this makes it visible in the charts (My guess is that this current is
used to detect a LiIon battery with). The charge current is the same on 12 volt
and usb power.
This charger might use -dv/dt terminations for NiMH.
The charger also has the pulsing after the charge is terminated and it does not
look like it will stop, this is perfectly fine for a NiMH battery.
充镍氢电池时开始用的是300mA,用时长了点，然而充锂电时在这个电流时用的比较短，
（我猜是，300mA的电流时来测试是锂离子还是镍氢的）用不同的适配器，如12V和5V USB,
测试电流都是相同的
This is the charge current, just after a NiMH battery is put into the charger,
it is pulsing with 300mA current.
我放上镍氢电池，开始的充电电流是300毫安，
After some time (about 10 minutes) it switches to the full 1A charge current,
but still pulsing. During the low part of the pulse it is discharging the
battery (The red curve is below the 0.0 line)
过了一段时间（大约是10分钟），开始用1A的电流充电你，中间会带有点脉冲，这个低部分的
脉冲就是开始开始对电池放点电，估计也是在充电过程中测试一下。
This is the charge current, just after a LiIon battery is put into the charger,
it is pulsing with 300mA current, it will after a few seconds change to the full
current.
这个图标，就是我放上锂电时的 只要几分钟充电电流就从300毫安，升到1A
Full charge current into a LiIon battery. This does not do any discharge in the
pulses.
在充锂电时，没有脉冲放电
The LiIon battery is full and the charger is pulsing and also doing a weak
discharge in between the pulses. The average will continue to charge the
battery. Note: I have changed scale.
锂电充满，充电器有个很小的脉冲放电电流，实际上，平均来说，还是在充电
注意，我改变了比例
Conclusion
结论
The charger has many interesting features: Charges both LiIon and NiMH, shows
charged capacity, detect bad batteries, shows charge state for LiIon.
But all these features are only interesting, if the charger does a good job. It
looks like it does a good job on NiMH and an acceptable job on LiIon, but I am
not impressed with the pulsing when the charge is supposed to be finished. The
discharge of a few mA is not really significant, except if leaving the batteries
in the charger for days.
充电器有很多特点。可以同时充锂电镍氢电池，可以显示容量，可以测试坏的电池，可以显示
锂电充电状态。这些特点都是很有趣，最重要的是能够充好电池。我觉得充满电，为什么还在
充电有点困惑，电池放到充电器里面，放电的电量很小，为什么还要充电。
Notes
注意
The charger was supplied by illuminationGear.com for a review.
Here is an explanation on how I did the above charge curves: How do I test a
charger
充电器在这个网站illuminationGear.com，可以参与评论
这里有些解释我是用什么测试得出这些曲线的，以及我怎么测试充电器的。
编者补充：
这个是我对测试者的 发出的疑问："液晶显示已经充满，为什们还在充电?这样会一直充下去，会损害电池 ”解释：
充电器显示充满时，其实并没有充满，大约充到了99%以上，液晶显示器显示了FULL,意思充
满了，其实还有1%没有充完。这个比分之一的用时 大约是30分钟，还能充劲几十毫安时的容量
工程设计人员认为： 在充电到99%时显示满了，可以提示客户你可以拿去用了，不必要再等
30分钟充剩下的1% 不过几十毫安时。但是你要是不拿走电池，充电器会继续充满剩下的比分之一。
以下是测试的图表来支持以上的结论
