ISO 16462-2014 PDF

Full title and description

St ISO 16462-2014 — Road vehicles — Connection to external electric power supply — Safety specifications. This standard defines safety requirements for the electrical connection between road vehicles (typically parked) and an external power supply for on-board systems such as battery charging, auxiliary power and electric vehicle supply equipment (EVSE) interfaces. It covers protective measures, connector characteristics and procedures to ensure safe connection and disconnection under various conditions.

Abstract

ISO 16462-2014 specifies safety-related requirements and tests for the interface between a road vehicle and an external electric power supply intended to provide electrical energy to the vehicle while stationary. The standard addresses protection against electric shock, thermal effects, short-circuit and overcurrent conditions, and requirements for the construction, marking and performance of connectors and inlet/outlet equipment. It aims to reduce hazards during connection, disconnection and service operations.

Scope

This standard applies to the electrical connection between a stationary road vehicle and an external electric power supply for the purpose of supplying energy to the vehicle. It is intended for use with vehicles that require an external electrical supply for charging batteries or operating on-board equipment while parked. ISO 16462-2014 addresses safety aspects of the connector, inlet/outlet, wiring and protective devices, and specifies tests to verify compliance with safety requirements. It does not cover dynamic charging systems in motion or details of vehicle propulsion systems beyond the connection interface.

Key topics and requirements

• Protection against electric shock for users and service personnel.
• Requirements for connectors, inlets and outlets including mechanical strength, degrees of protection and clear marking.
• Current-carrying capacity and thermal performance limits to prevent overheating.
• Short-circuit and overcurrent protection requirements and compatible protective devices.
• Requirements for isolation, earthing/grounding, and polarity to ensure safe operation.
• Operational tests for connection/disconnection, durability and environmental performance (e.g., temperature, moisture, corrosion).
• Labeling, instructions and safety information for installers and users.

Typical use and users

ISO 16462-2014 is typically used by automotive manufacturers, EV system designers, EVSE (charging equipment) manufacturers, component suppliers (connectors, inlets), test laboratories and regulatory bodies concerned with vehicle electrical safety. It is referenced by specifiers and procurement teams when selecting or verifying external power connection interfaces for passenger cars, light commercial vehicles and similar road vehicles that accept external electrical supply while stationary.

Related standards

Related standards include vehicle electrical systems and charging interface standards, safety standards for electrical equipment, and regional EVSE specifications. Examples typically referenced alongside ISO 16462-2014 are standards covering vehicle connectors, general road vehicle electrical safety, charging station equipment, and standards for electrical safety and EMC. Implementers often use ISO 6469 series (electrically propelled road vehicles), IEC 61851 (electric vehicle conductive charging system), and national regulations or connector specifications to ensure compatibility.
