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.

EN 62040-1

The European adoption of IEC 62040-1, the safety standard for uninterruptible power systems with an AC output and an energy storage device — usually a battery behind a DC link — on low-voltage networks up to 1 000 V AC or 1 500 V DC. The battery room or cabinet itself also falls under IEC 62485-2.

IEC 62133

The safety standard for portable sealed cells and batteries, part 2 covering lithium systems. Passing it is a basic requirement for consumer products, and it is often the first safety certification a new cell obtains.

IEC 62660

The international standard series for lithium-ion cells in electric vehicles: part 1 performance testing, part 2 reliability and abuse testing, part 3 safety requirements. It fixes test conditions so results from different labs can be compared.

IEC 63056

The safety standard for lithium battery systems in electrical energy storage, building on IEC 62619 with system-level requirements for the electronics, enclosure and installation of stationary storage.

Stationary storage

Batteries installed in a fixed place — a container at a solar farm, a cabinet in a home — to shift energy in time or support the grid. LFP cells dominate because cost per cycle and safety matter more than mass.
