Conformity assessment and CE marking

The procedure by which a manufacturer shows a battery meets the EU Battery Regulation — safety, performance, durability and labelling — before affixing the CE mark. For EV and industrial batteries a notified body is involved; the Regulation replaces the Low Voltage Directive route the old rules used.

IEC

The body that publishes the international standards for electrical technology, including IEC 62133 and IEC 62660 for cells and the IEC 60050 vocabulary, whose part 482 defines battery terms. National bodies adopt its standards with local prefixes.

Intrinsic safety

Protection of equipment used in explosive gas or dust by limiting electrical and thermal energy, so that neither a spark nor a hot surface can ignite the atmosphere even with faults present. Under IEC 60079-11, Ex ia tolerates two faults and is allowed in Zone 0. The battery is the hardest part: its short-circuit current and surface temperature must stay below ignition limits.

Lithium–thionyl chloride cell

A 3.6 V primary cell in which liquid thionyl chloride is both the electrolyte solvent and the positive reactant, reduced on a porous carbon electrode. A protective lithium chloride film keeps self-discharge around 1 % a year, so cells run utility meters and trackers for 10–20 years, but it also causes a voltage delay when a load is first applied.
