The maximum rated voltage for machines and battery packs is 75 V d.c.
Battery machines covered by this document are not considered to be class I tools, class II tools or class III tools and therefore are not required to have basic insulation, supplementary insulation or reinforced insulation. Electric shock hazard is considered to exist only between parts of opposite polarity.
This document deals with the hazards presented by machines which are encountered by all persons in the normal use and reasonably foreseeable misuse of the machines.
When evaluating a rechargeable battery pack for protection against electric shock during charging, creepage distances, clearances and distances through insulation, the relevant requirements of this document are applicable with the battery pack fitted to the intended charger.
Since rechargeable battery packs for machines are submitted to different use patterns (such as rough use, high charging and discharging currents), their safety can be evaluated only by this document and not by using other standards for rechargeable battery packs, such as IEC 62133-1:2017 or IEC 62133-2:2017, unless otherwise indicated in this document. All relevant aspects related to the safety of rechargeable batteries are addressed in this document, such that the requirements of IEC 62133-1:2017 or IEC 62133-2:2017 are not required to be separately applied.
When evaluating the risk of fire associated with rechargeable battery packs for machines, consideration has been given to the fact that these battery packs are unattended energy sources and have been evaluated as such in this document. Requirements in other standards regarding the risk of fire due to the charging of these battery packs are therefore considered to be fulfilled.
This document also addresses requirements covering the use of lithium-ion cells employed in battery systems in machines. The following is considered within the context of these requirements:
– These requirements address the risk of fire or explosion of these batteries and not any possible hazards associated with toxicity nor potential hazards associated with transportation or disposal.
NOTE 3 IEC 62281:2019 covers the safety aspects of lithium-ion batteries during transport.
– Battery systems covered by these requirements are not intended to be serviced by the end user.
– These requirements are intended to provide comprehensive evaluation of a battery only if used in products covered by this document.
– These requirements address the safety of lithium-ion battery systems during storage and use including discharge and charge. These requirements are only considered to be supplementary requirements in regard to battery charger fire and electric shock.
– These requirements refer to and require parameters supplied in reference to the cells that establish conditions for safe use of those cells. Those parameters form the basis of acceptance criteria for a number of tests contained herein. This document does not independently evaluate the safety of cells. These parameters, taken as a set, constitute the "specified operating region" for a cell. There can be several sets of specified operating region(s).
This document does not apply to machines using general purpose batteries installed by the user and this document alone will not be sufficient to ensure that all hazards are considered for these products.
This document does not apply to the safety of battery chargers themselves.
NOTE 4 IEC 60335-2-29 covers a variety of chargers.
IEC 62841-1:2014, Clause 1 is applicable, except as follows.
Addition:
