Scope

This part of IEC 62933 applies to those instances when a BESS undergoes unplanned154 modifications. Such modifications can involve one or more of the following:

– changes of a subsystem component using non-OEM parts,

– changes to mode of operation,

– changes of installation site, or

– changes in an accumulation subsystem due to an installation of reused or repurposed batteries.

Any such modification shall not impair the original state of safety of the BESS.

This document complements IEC 62933-5-2, which relates to the overall safety aspects of a BESS.

The requirements covered by this document are applied in addition to the requirements in IEC 62933-5-2 in accordance with each situation
