3 Performance And Test Conditions (电池性能及测试条件)
3.1 Standard Test Conditions(标准测试条件)
Test should be conducted with new batteries within one week after shipment from our factory and the cells shall not be cycled more than five times before the test. Unless otherwise specified, test and measurement shall be done under temperature of 20±5℃ and relative humidity of 45~85%. If it is judged that the test results are not affected by such conditions, the tests may be conducted at temperature 15~30℃ and humidity 25~85%RH.
测试必须使用出厂时间不超过一个星期的新电池,且未进行过五次以上的充放电循环。除非特别说明,否则测试会在温度20±5℃,相对湿度45~85%的条件下进行。如果经鉴定测试结果不受上述条件影响,测试也可以在温度15~30℃,相对湿度25~85%RH的条件下进行。
3.2 Measuring Instrument or Apparatus(测量器具及设备)
3.2.1 Dimension Measuring Instrument(尺寸测量器具)
The dimension measurement shall be implemented by instruments with equal or more
precision scale of 0.01mm.
尺寸测量器具的精度等级应不小于0.01 mm 。
3.2.2 Voltmeter(伏特计)
Standard class specified in the national standard or more sensitive class having inner impedance more than 10kΩ/V
按照国家标准指定规格等级或采用灵敏度更高的,测量电压时内阻不应小于10kΩ/V。
3.2.3 Ammeter(安培计)
Standard class specified in the national standard or more sensitive class. Total external
resistance including ammeter and wire is less than 0.01Ω.
按照国家标准指定规格等级或采用灵敏度更高的,包括电流表及电线在内的总外阻应小于0.01Ω。
3.2.4 Impedance Meter(电阻计)
Impedance shall be measured by a sinusoidal alternating current method(1kHz LCR meter).
内阻测试仪测量原理应为交流阻抗法(1kHz LCR)。
3.3 Standard Charge\Discharge(标准充放电)
3.3.1 Standard Charge :Test procedure and its criteria are referred as follows:
标准充电:测试过程及标准如下:
Charging shall consist of charging at a 2A constant current rate until the Battery Pack reaches 16.8V. The Battery Pack shall then be charged at constant voltage of 16.8 volts while tapering the charge current. Charging shall be terminated when the charging current has tapered to 50mA. Charge time: Approx 4h, The cell shall demonstrate no permanent degradation when charged between 0 ºC and 45 ºC.
电池先2A恒流充至16.8V,当充电电流逐渐减小时再以16.8V恒压充至电流减小到50mA,充电时间大约为4个小时。在0℃-45℃内充电电池应没有永久损害。
3.3.2 Standard Discharge(标准放电)
Battery Pack shall be discharged at a constant current of 5A to 11 volts @ 20± 5℃
电池以5A恒流放电至11V @ 20± 5℃
3.3.3 If no otherwise specified, the rest time between Chare and Discharge amount to 30min.
如果没有特别说明,电池充放电间隔时间为30分。 |
