The standard EN 50147-1 (often cited as EN 50147-1:1996) is the primary European reference for measuring the shielding effectiveness (attenuation)
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 (Functional Safety), requiring engineers to document how the BMS detects faults and mitigates hazards.
The European standard EN 50147-1 is a critical document for anyone involved in electromagnetic compatibility (EMC) testing, chamber construction, or high-frequency engineering. It specifically defines the measurement procedures for the shielding attenuation of anechoic chambers and shielded rooms. iTeh Standards Why EN 50147-1 Matters
