EN 62619 is the European adoption of IEC 62619, specifying safety requirements for secondary lithium cells and batteries for use in industrial applications. Published by CENELEC, it covers stationary energy storage systems, industrial motive power, uninterruptible power supplies, and other non-road-vehicle industrial uses of lithium batteries. The standard is the European harmonised reference for industrial lithium battery safety and supports CE marking under the Low Voltage Directive and compliance with the EU Battery Regulation.

Designation: EN IEC 62619:2022
Based on: IEC 62619 (identical technical content)
UK equivalent: BS EN IEC 62619
Scope
EN 62619 applies to secondary lithium cells and batteries for industrial applications, explicitly excluding road vehicle traction batteries (covered by vehicle type approval standards) and portable consumer batteries (covered by EN 62133-2). Industrial applications within scope include grid-connected battery energy storage systems (BESS), UPS systems, industrial trucks and automated guided vehicles (AGVs), telecommunications backup power, and railway auxiliary power.
Key Requirements and Tests
EN 62619 specifies abuse tests at cell and battery level including overcharge, forced discharge, external short circuit, thermal abuse (oven heating), mechanical crush, and drop tests. The standard also requires that battery systems incorporate a battery management system (BMS) with defined protective functions — including overvoltage, undervoltage, overcurrent, and overtemperature protection — and that the BMS has been verified to operate correctly. This BMS requirement distinguishes EN 62619 from cell-only safety standards and makes it relevant to complete battery system design.
European Market Relevance
EN 62619 compliance is a standard element of CE marking for industrial lithium battery systems under the Low Voltage Directive (2014/35/EU) and the Machinery Directive for battery-powered industrial vehicles. For grid-connected BESS systems, EN 62619 is referenced alongside EN IEC 62485-5 and NFPA 855 equivalents in European grid operator connection requirements. The EU Battery Regulation (2023/1542) encompasses industrial batteries within its scope, and EN 62619 forms part of the conformity assessment pathway for industrial batteries placed on the European market.
