IEC 62660

What this standard covers, in our words

A three-part series for the cells inside a ROAD vehicle's traction pack — Part 1 performance testing (2018), Part 2 reliability and abuse testing (2018), Part 3 safety requirements (2022). Part 3's own scope names battery electric and hybrid electric vehicles. It is a CELL standard: it tests cells and cell blocks, on the stated premise that they are afterwards used inside a pack within the limits the cell maker sets. A maker citing "IEC 62660" with no part number has named a series rather than a standard.

This is our summary, not the standard’s own wording — IEC (International Electrotechnical Commission) publish the text itself and it is the document to read before relying on anything here.
