EN IEC 62984-2:2020 pdf free.High-temperature secondary batteries – Part 2: Safety requirements and tests (IEC 62984-2:2020).
lf relied upon for maintaining the cells within their specified operating range,the battery management system(BMS) shall maintain cells within the specified voltage,temperature and current during standby, charging and discharging of the battery.
A battery system shall be provided with a thermal management control to ensure safe operation of the battery, including its internal heaters and to prevent the battery from being overheatedor otherwise used outside of its specified operating temperature range. The batterymanagement system shall prevent the battery from entering a hazardous state as a result of failure of the thermal management control.
Heaters used to maintain the cells at specified operating temperatures shall be dimensioned for the current and voltage involved and designed to prevent breakages and short circuits from occurring as a result of handling, installation and operation of the battery.
NOTE Good thermal management provides a good level of efficiency.
Subclause 5.2.1 of lEC 62984-1:2020 is applicable with the following additional text:
The enclosure and mechanical support structure(s) for the battery arrangement shall have the strength and rigidity required to resist the possible physical abuses that it will be exposed to during its transport, installation and intended use, in order to reduce hazards.
The battery shall be capable of withstanding, with no harm to users, the vibrations and shocks likely to occur during its transportation,storage,installation and operation according to the intended application (stationary or mobile).
The requirements of 5.2.1 apply not only to modules, but also to the complete battery installation,including module interconnections and supporting structure.
Protection against electric shock for class l, ll or lll equipment is applicable to those parts accessible under normal conditions. ELV,PEB,PELV and SELV systems provide protection from electric shock by hazardous-live-parts, and are not necessarily related to a class l, ll or lll equipment class.
Any conductive part that is not separated from the hazardous-live-parts by at least basic insulation shall be considered to be a live part.
An accessible metallic part is considered to be conductive if its surface is bare or is covered by an insulating layer which does not comply with the requirements of basic insulation.EN IEC 62984-2 pdf download.
