IEC62133中電池安全測試設備要求

2010年09月08日 08:37:07人氣:1560來源:東莞市貝爾試驗設備有限公司

今年起(2010年10月26日),電池類產品如欲取得CB認證證書,除按照UL 1642測試外,還須進行額外測試,以確保它們符合電池安全標準IEC 62133的要求。在特定的過渡期結束后,即從2011年6月27日起,IEC 62133標準將全面取代UL 1642,電池類產品取得CB證書只須符合IEC 62133的要求。

*,電池使用不當,會導致如燒傷和火災等事故。近年來電池安全事故頻傳,美國、日本、俄羅斯等國均強制要求電池按照專門標準進行檢測。我國作為電池出口大國,占據一半以上的生產產量。近年來,寧波地區電池產業發展勢頭迅猛,上百家制造企業中涌現出口不少,已成為浙江省初具規模的電池生產基地,今年1-10月,已有2.35億美元電池出口順利出口至美國、歐盟、日本東南亞、中國臺灣等各個國家和地區。

電池產業正處于結構升級的關鍵階段,積極拓展出口市場意義重大。檢驗檢疫專家指出,獲取CB證書的電池產品在申請進口國所要求的其它認證證書時,可免除或減少再送樣測試,大大縮短產品進入市場的周期,減少成本費用,加速產品出口。而IEC 62133標準主要包含電芯和電池項目的測試,由于電池的制造和成品檢測的復雜性,電池制造企業在檢測驗證前應對該標準細節有詳細了解并在生產中加以控制,如在電芯設計考慮耐持續充電能力,以免在zui終檢測中因為不符合IEC 62133標準要求而阻礙出口。

IEC62133 對電池安全性能測試的要求總括:

1. 耐振動測試(Vibration )

具體要求:電池在充滿電的情況下進行振動,振幅為0.76mm, 以1HZ/MIN 的頻率,在10HZ~55HZ 的條件下振動(10HZ~55HZ~10HZ為一個循環),在90±5min 內恢復電池。

Fully charged cells or batteries are vibration-tested under the following test conditions and

the sequence in Table 2. A simple harmonic motion is applied to the cells or batteries with

an amplitude of 0,76 mm, and a total maximum excursion of 1,52 mm. The frequency is

varied at the rate of 1 Hz/min between the limits of 10 Hz and 55 Hz. The entire range of

frequencies (10 Hz to 55 Hz) and return (55 Hz to 10 Hz), is traversed in 90 min ± 5 min

for each mounting position (direction of vibration). The vibration is applied in each of three

mutually perpendicular directions, in the sequence specified below.

Step 1: Verify that the measured voltage is typical of the charged product being tested.

Steps 2-4: Apply the vibration as specified in Table 2.

connecting the positive and negative terminals with a total external resistance of less than

100 mÙ. The cells or batteries remain on test for 24 h or until the case temperature

declines by 20 % of the maximum temperature rise, whichever is the sooner.

subjected to a total of three shocks of equal magnitude. The shocks are applied in each of

three mutually perpendicular directions. At least one of them shall be perpendicular to a

flat face.

For each shock the cell or battery is accelerated in such a manner that during the initial

b) Test

Each fully charged cell is crushed between two flat surfaces. The force for the crushing is

applied by a hydraulic ram exerting a force of 13 kN ± 1 kN. The crushing is performed in

a manner that will cause the most adverse result. Once the maximum force has been

applied, or an abrupt voltage drop of one-third of the original voltage has been obtained,

the force is released.

A cylindrical or prismatic cell is crushed with its longitudinal axis parallel to the flat

surfaces of the crushing apparatus. To test both wide and narrow sides of prismatic cells,

a second set of cells is tested, rotated 90° around their longitudinal axes compared to the

first set.
