Battery Management System Or Unit (BMS, BMU): electronic system associated with a battery which monitors
and/or manages its state, calculates secondary data, reports that data and/or controls its environment to influence the
battery's performance and service life and has the functions to cut off in case of abnormal conditions (e.g. over
charging, over current and over heating and charge balancing between cells or parallel cells blocks)
NOTE 1: Depending on the application and its size, the function of the BMS/BMU can be assigned to the battery
cell, module, string, pack or system and equipment using the battery. A common implementation is a
BMS/BMU made of several electronic modules located at different levels of the system.
NOTE 2: A Battery Management System (BMS) is sometimes also referred to as a Battery Management Unit
(BMU).
NOTE 3: As in ETSI TS 103 553-2 [i.3].
NOTE 4: Adapted from IEC 60050-482 [i.7] and IEC 62620 [i.8].
ETSI
8 ETSI ES 202 336-11 V1.2.1 (2025-09)
battery string: group of cells or battery modules of same technology and capacity connected in series to match the
battery system voltage
NOTE 1: As in ETSI TS 103 553-2 [i.3].
NOTE 2: Strings can work in parallel with or without protective device (e.g. fuse or PTC) depending on the
technology and safety risk.
battery system: system which incorporates one or more battery cells, modules, strings or battery packs and has one or
more BMS or BMU
NOTE 1: As in ETSI TS 103 553-2 [i.3].
NOTE 2: Adapted from IEC 60050-482 [i.7] and IEC 62620 [i.8].
NOTE 3: The battery system is generally defined for high power and capacity batteries made of several battery
strings or packs of blocks or modules it may include cooling or heating units and gas exhaust
arrangement.
battery unit: energy storage system providing power to the telecom load comprised of a battery cell string
client post: any device (laptop, PDA, console, etc.) connected to servers via the operation system networks to perform
maintenance or supervision operations
NOTE: As in ETSI ES 202 336-1 [1]).
Data Gathering Unit (DGU): functional unit used for several functions:
• collect serial, digital and analogue data from several equipment;
• option to send (output) serial or digital commands;
• forward/receive information to/from the Local/Remote Management Application via agreed protocols;
• mediation between interfaces and protocols
NOTE 1: This function may be integrated as part of specific equipment.
NOTE 2: As in ETSI ES 202 336-1 [1].
Dynamic Name Server (DNS): associates a single domain name to an IP address
NOTE: As in ETSI ES 202 336-1 [1].
event: any information signalling a change of state which is not an alarm: e.g. battery test, change of state of battery
charge
NOTE 1: The event signal should be understood by itself by an operator and should always have at least one
severity qualification or codification (colour, level, etc.). It should be transmitted in a formatted structure
