Table 1 01 provides an alphabetical cross-reference listing of terms.
3.1 01 arc fault detector
AFD device or group of devices to detect arcs
Note 1 to entry: This note applies to the French language only.
3.1 02 arc fault interrupter
AFI device able to interrupt arc faults triggered by an arc fault detector
Note 1 to entry: This note applies to the French language only.
3.1 03 battery management system
BMS electronic system associated with a battery which has functions to cut off or disconnect it in case of overcharge, overcurrent, overdischarge, and overheating
Note 1 to entry The BMS monitors and/or manages the battery’s state, calculates secondary data, reports that data and/or controls the battery’s environment to influence its safety, performance and/or service life.
Note 2 to entry Cut-off or disconnection due to overdischarge is not mandatory if there is an agreement between the cell manufacturer and the GCPC manufacturer.
Note 3 to entry The function of the BMS can be assigned to the battery pack or to equipment that uses the battery.
Note 4 to entry The BMS can be divided and it can be found partially in the battery pack and partially on the
equipment that uses the battery.
Note 5 to entry The BMS is sometimes also referred to as a BMU (battery management unit).
Note 6 to entry: This note applies to the French language only.

rephrased.]
3.1 04 battery system
BS system which comprises one or more cells, modules or battery packs
Note 1 to entry It has a battery management system to cut off or disconnect it in case of overcharge, overcurrent, overdischarge, and overheating. Where cells, modules and battery packs employ an acid electrolyte, the BMS may be absent from the battery system provided that the BMS functions are integral to the BS section
Note 2 to entry Cut-off or disconnection due to overdischarge is not mandatory if there is an agreement between the cell manufacturer and the GCPC manufacturer
Note 3 to entry The battery system may have cooling or heating units.
