2022年8月29日，IECEE官網(wǎng)發(fā)布關(guān)于電池CTL決議DSH 2182，涉及標準IEC 62133-2:2017，IEC 62133-2:2017/AMD1:2021.

內容如下：

Question問(wèn)題

The second charging procedure for test purposes, Clause 7.1.2, requires a charging cutoff current of 0.05ItA. When cell manufacturer defines a different charging cutoff current, which one shall be used?

用于測試目的的第二個(gè)充電程序，第 7.1.2 章節，要求充電截止電流為0.05ItA。當電池制造商定義不同的充電截止電流時(shí)，應使用哪一個(gè)？

Decision決定

0.05ItA shall be used.

However, on request of the manufacturer, a separate set of tests with samples prepared with a manufacturer-defined cutoff current can be conducted for reference purposes. The upper limit charging voltage of cell shall not be exceeded while charging with the manufacturer-defined cutoff current.

應使用 0.05ItA。

但是，根據制造商的要求，可以對使用制造商定義的截止電流制備的樣品進(jìn)行一組單獨的測試，以供參考。 以制造商定義的截止電流充電時(shí)，不得超過(guò)電池的充電上限電壓。

Explanatory notes  解釋性說(shuō)明

The charging cutoff current carries an implication on the state-of-charge of the samples and the probability of test compliance.

Therefore the value defined in the standard, 0.05ItA, shall be strictly followed. On the other hand, considering that cell manufacturers design their products with a possibly different charging cutoff current to reflect intended usage conditions, it is allowable to conduct a separate set of tests with that charging cutoff current in addition to 0.05ItA.

Testing with this different charging cutoff current is for reference purpose only. In accordance with Clause 7.1.2, the upper limit charging voltage of the cell shall not be exceeded, regardless of the value of charging cutoff current.

充電截止電流對樣品的充電狀態(tài)和測試合格的可能性有影響。因此，應嚴格遵循標準中定義的值0.05ItA。另一方面，考慮到電池制造商根據預期的使用條件設計其產(chǎn)品可能具有不同的充電截止電流，因此允許單獨設置 該充電截止電流除 0.05ItA外的測試次數。以這種不同的充電截止電流進(jìn)行測試僅供參考。

根據第 7.1.2 章節，無(wú)論充電截止電流值如何，均不得超過(guò)電芯的充電上限電壓。
