EN 50147-1 places significant responsibility on the Battery Management System (BMS). It is not enough for the cells to be chemically stable; the electronics must actively monitor and interrupt currents. This ties the standard closely to ISO 26262 (Functional Safety), requiring engineers to document how the BMS detects faults and mitigates hazards. en 50147-1 pdf

Measurements must be performed at a sufficient number of frequencies to identify resonances. Typical step sizes:

The central pass/fail metric for the abuse tests is the requirement that the REESS must not catch fire or explode. This is the "golden rule" of the document. If a cell vents but does not ignite, the test is often considered a pass, provided other criteria (like isolation resistance) are met. This focus on catastrophic failure prevention makes the standard robust for consumer safety.
