laboratory
a.优势提炼：Sresky pays great attention to raw materials, semi-finished products , finished
products and New materials testing. We have professional outdoor and indoor simulation test
instruments and equipment to ensure that the products received by customers are verified by
professional tests and field simulation tests. Are all qualified products!
b. ASS acetate spray test equipment: （ASS 醋酸盐雾测试设备）
所有产品的五金件来料检验均要经过盐雾测试，ASS 醋酸盐雾测试 24 小时相当于室外自然
条件 3 年，我们是做 72 小时实验，相当于室外自然条件 9 年的抗腐蚀型合格
All of the product hardware need to pass the salt spray test. ASS acetate spray test is equivalent
to outdoor natural conditions for 3 years. And we are doing 72 hours of experiment, means 9
years of outdoor natural conditions.
实验原因：由于室外灯具使用条件时非常苛刻的，耐候性是灯具必须的指标之一，此设备
可以快速对材料的耐候性做出判定
Experimental reason: Because the outdoor lighting conditions are very demanding, weather
resistance is one of the necessary indicators of the luminaire, and this equipment can judge the
weather resistance of the material quickly.
c. Constant temperature & humidity, high and low temperature test equipment
所有供应商的锂电池都要经过高温摄氏 55°充放电循环测试，测试 100 循环电池衰减在 5%
以内判断合格，才能使用---只有我们才花这么多时间去做的实验
All of lithium batteries from suppliers must pass the high temperature 55℃ charge and
discharge cycle test, we always test 100 cycles and with 5% power reduction can be
acceptable---from our research only Sresky factory do this kind of tests, because it will take much
extra time and work, and costs extra spending.
实验原因：室外高温是电池寿命的杀手，在高温下电池寿命衰减很快，我们必须选择正确
的耐高温电芯才能保证产品有足够的耐用性。
Why Sresky must do this? because we know that Outdoor high temperature is the killer of
battery . At high temperature, battery life decays very quickly. We must choose the right high
temperature battery to ensure the product has sufficient durability.
d. Battery pack capacity tester 电池包分容测试仪
生产线 PACK 好的锂电池包都要抽样经过电池包老化测试仪充放电循环测试，测试电池包的
充放电容量、过充、过放保护是否合格才能使用到成品上. 一般厂家都没有这个设备
The battery pack from the production lines must be tested by the battery pack aging tester for
charge and discharge cycle test. After the tests passed the capacity check, overcharge and
overdischarge protection ,then can be used to the finished products . As it’s will costs extra time
and work, and extra machine cost, so very few factory do this , why Sresky must do it?
测试原因：电池包包含电芯，以及对电芯起保护作用的保护板（PCM），经过复杂的制造工
艺组合在一起；我们需要针对组合成的电池包做一系列的测试，以确保所有的组成部分都
可以正常工作。
Because The battery pack contains cells and protective plates (PCM) that protect the cells, they
are combined by a complex manufacturing process. We need to do some testing on the
assembled battery pack to make sure all the components work well.
e. Integrating sphere of LED

4. Battery pack PACK line
a.优势提炼：Sresky 非常重视电池的安全性和工作稳定性，我们很清楚锂电池是有危险的，
如果保护或组装不得当，很容易出现安全隐患，所以我们在组装电池包的过程中，对原材
料电芯的检测和电池组以及成品的检测流程非常的精细专业，杜绝一切可能在实际使用过
程中产生的问题，尤其是在高低温的情况下，确保电池能够正常安全的工作，同时使用寿
命有保证。
Sresky attaches great importance to the safety and stability of the battery. We know that the
lithium battery is dangerous.
If it is protected or assembled improperly, it is easy to have
safety hazards. Therefore, in the process of assembling the battery pack, the raw material battery
cell and finished product inspection process are all very precise and professional, to eliminate all
problems that may occur during actual use, especially in the case of high and low temperature, to
ensure that the battery can work normally and safely, also the lifetime is guaranteed.
b.原材料电芯--高温静置筛选
Sresky 对所有的电芯原材料做 100%的高温静置筛选，检验出在高温下出现容量衰减的电芯，
排除电池内部存在的易燃易爆等不良隐患
几乎没有厂家做这道工序，因为耗时耗费用
Sresky performs 100% high temperature and room temperature static test for all the in coming
battery cell materials. The battery cell on the production line must pass the 7-day high
temperature 55° test and then the 7-day normal temperature test.
If the battery performance
test OK can be assembled on the line, and if it fails, it will be returned to the supplier. The
test reason is to select out the bad battery cells which as capacity reduction and eliminate the
hidden dangers such as flammable and explosive inside the battery.
this tests because costs extra time and money.
c. Battery Sorter
Very few factories do
有这个设备的厂家不多
电池要经过内阻、电压的分选和配对，确保每个电池包内电池性能一致
原因：电池包由多颗电池构成, 每颗电池都有其自身特性, 在使用时不考虑其特性，将会导
致整个电池包寿命降低, 因此需要将特性接近的电池组合在一起，寿命才是最合理最长久的。
Why use it? We know that each battery cell has different characteristics, such as different
current, voltage and resistant, this machine will do fast check and select the similar
characteristic battery cells and pack them together into a battery pack. Then this kind of
battery pack can get much better and stable performance and much longer life time. Max
charging and discharging the inner battery power.
d. Battery automatic spot welding machine
有这个设备的厂家不多
