Full title and description

St UL 1564 2024-02 — Standard for Industrial Battery Chargers (UL 1564, Edition 5, published February 13, 2024). This standard specifies safety, construction, performance and test requirements for industrial battery chargers intended to charge storage batteries used in motive equipment and similar industrial applications.

Abstract

UL 1564 (Ed. 5, 2024) establishes requirements for battery chargers rated 600 volts or less used with industrial storage batteries (for example, motive equipment such as forklifts and personnel carriers). The edition includes editorial updates, alignment of dielectric voltage-withstand testing, and specific test and marking requirements to ensure safe operation, construction integrity and proper installation/usage guidance.

Scope

UL 1564 covers industrial battery chargers rated 600 V or less that are intended to charge industrial storage batteries used to power motive equipment such as material handling trucks, tractors and similar equipment. The standard addresses both cord-and-plug and permanently connected chargers and defines exclusions (for example, certain marine chargers, household chargers, automotive starter chargers and chargers for fire-protection signaling service are outside the scope). The standard is intended for use in conjunction with the National Electrical Code (NFPA 70) and other applicable installation rules.

Key topics and requirements

• Definition of product types and ratings (voltage limits, intended applications).
• Construction and material requirements to ensure electrical and mechanical safety.
• Dielectric (voltage-withstand) and insulation testing requirements and alignment notes for testing methods.
• Protection against overload, overtemperature and abnormal conditions; grounding and bonding requirements.
• Output and charging circuit safety: control, sensing, and protective circuitry requirements.
• Marking, labeling and instructions requirements for safe installation, operation and maintenance.
• Performance and environmental tests (temperature, humidity, mechanical stress, short-circuit/fault conditions where applicable).
• Requirements for partial assemblies and chargers intended to be installed as components of larger end-use equipment.

These topics summarize the main safety and performance areas emphasized in the 2024 edition.

Typical use and users

Primary users include industrial battery charger manufacturers, OEMs for material-handling and motive equipment (forklifts, personnel carriers), product safety and compliance engineers, test labs and certification bodies, procurement/specification teams, and regulatory/inspection authorities. Test laboratories and certification services (including UL testing services) use UL 1564 as the basis for evaluating and listing industrial chargers.

Related standards

Standards and documents commonly referenced alongside UL 1564 include ANSI/UL 1012 (power units), ANSI/UL 1236 (battery chargers for engine-starter batteries), IEC/ISO safety and household charger standards where applicable (for non-industrial chargers), and the National Electrical Code (NFPA 70) for installation requirements. IEC 60335-2-29 (battery chargers — household and similar) and other battery/charging related ICS documents are often consulted for cross-reference and harmonization.
