对于多串并电池,第一次制样及第一次量产时，项目部需送3PCS到实验室进行容

量及压差测试。

For the series and parallel battery, when first made sample and first mass production, prj need send 3

pcs samples

To lab do the capacity and cell balance check.

产品进入EVT阶段，实验室负责完成设计验证

At EVT step, laboratory. is in charge of complete design verification

项目部负责提供样品给实验室

Project is in charge of provide the test samples to laboratory

Design change（设计变更）

如接下来设计有变更，R&D需针对变更项目及有影响项目重新测试，项目部需重新送样至实验室，实验室针对变更项目进行再次验证测试

When the product design changed in next step, R&D must retest the affected items by the change retested, and PRJ need to apply for afresh test. According to the change lab will do the related test

Sample quantity：（测试数量）

根据测试标准，每一项测试需要测试验证3pcs，如有特殊要求，可以根据需要适当调整测试数量

. For the test criteria, for each test item need 3pcs sample to verification. if there have special requests, it can

adjust the test quantity by need

Test item（测试项目）

参考附件二

Reference the attachment two

当客户有特殊要求时，各项目的测试方法及判定条件按客户要求；

The test method and criteria shall been in accord with the customer demand.

当实验室无法进行相关测试时，由项目部统一申请外送给有资质的供应商测试；

When it can’t be test by lab, prj shall apply for testing by the professional vendor.

样品测试完成后，测试人员须参照QSI-025-FM015A完成设计验证报告，再将测试报告交由实验室工程师及TE经理审批存档，并影印一份副本或者以邮件形式发给相关人员。

After finished the test, tester should follow QSI-025-FM015A finished the report and submit to reliability engineer and TE Manager for approving, lastly make a copy of report or send report to the correlative persons.

可靠性测试的品质目标是零不合格。当测试不合格时，立即通知测试/项目/研发/品质部门等相关部门，组成FA分析小组一同对不合格进行原因分析，并制定纠正预防措施，且此批产品按照QEP-023≤不合格品控制程序≥处理；若该批次产品已出货给客户，须立即通知客户

The target of reliability test is zero reject rate, if fail, immediately notify TE/PRJ/QA Related department, create FA Group to analyze the root cause then take corrective

and preventive action, this product shall be handled according toQEP-023 ≤Non-conforming Control Procedure≥, If this product had been shipped, we shall inform customer Immediately

6 Named rules(测试报告命名规格)

测试命名为测试类型+机种名称+发行日期+流水号，测试类型有设计验证（DT），可靠测试(RT)，抽样

测试(OT)三种类型

例如：8708可靠性振动测试报告，发行日期为2013-10-12，流水号为1 则命名为：

RT-NNB8708-Vibration Test Report 01

Test type named + model name + issue date + serial number, test types for design verification (DT), reliable

testing (RT), sampling test (OT) there tapes

Such as: 8708 reliable vibration test, release date for the 2013-10-12, serial number 1 is named

RT-NNB8708-Vibration Test Report 01

振动

vibration test

将电池稳固地有保护地固定在振动平台上，不要

扭曲电芯，以便振动能很好的传送，振动频率按正弦

波形在15分钟内按对数方式从7 Hz扫描到200 Hz 再

回到7 Hz，振动沿电芯互相垂直地三个方向进行，每

一个方向按上述循环重复12次，用时共3小时，振动

方向中的一个必须垂直电芯和电池的最大面；对数扫

描频率如下：维持1gn的峰值加速度，从7 Hz一直扫

描到18 Hz，振幅维持在 (整个行程，同时频率增长，

直到峰值加速度达到8gn（约50 Hz），然后维持8gn

的峰值加速度，直到频率增长到200Hz

fix up the battery on the vibration plat, the

frequency use sine wave from 7HZ to 200HZ in 15

minutes and down to 15 HZ ,the there vibration

direction each other perpendicularity, each

direction repeat 12 times, total 3 hours;

logarithm scan frequency as below, keep 1gn peak

acceleration, from 7HZ to 18HZ,the extent
