Overview
IEC TS 63066:2017 is an IEC Technical Specification for low-voltage docking connectors for removable energy storage units. It defines requirements for accessories (docking connectors) that are incorporated in or fixed to electrical equipment to connect removable energy storage units (such as batteries) to a dedicated power conversion unit, an energy-consuming unit, or another energy storage unit. Edition 1.0 was published March 2017. This TS addresses design, safety, testing and environmental performance for low-voltage connector interfaces used in modular and removable energy storage systems.
Key Topics and Technical Requirements
The specification covers a comprehensive set of technical topics and test requirements relevant to docking connectors:
- Scope and definitions for low-voltage docking connectors and related accessories.
- General construction and design requirements including dimensions, marking and type classification.
- Electrical safety: protection against electric shock, insulation resistance, dielectric strength and conditional short-circuit current tests.
- Earthing and terminals: provisions for earthing, screw and current-carrying part requirements, terminations.
- Mechanical requirements: mechanical endurance, strength, mating/unmating cycles and interlocks.
- Thermal and electrical performance: temperature rise, electrical endurance, contact resistance.
- Climatic and environmental testing: dry heat, damp heat, thermal change, salt stress and corrosion resistance; environmental performance classes (including an informative annex for vehicle classes).
- Misalignment and mechanical severities: defined misalignment tolerances, operation with misalignments and dynamic mechanical severities.
- Electromagnetic compatibility (EMC) considerations and testing expectations.
- Annexes and examples: test cycle details and accessory examples illustrating practical designs.
Applications
IEC TS 63066 is intended for use wherever removable energy storage units are connected via low-voltage docking connectors, including:
- Battery swap systems and modular battery packs
- Portable energy storage modules for stationary storage or microgrids
- Electric vehicles and light commercial vehicles (informative vehicle environmental classes included)
- Consumer and industrial equipment using removable battery modules
The standard helps ensure safe, reliable electrical and mechanical interfaces between batteries and host equipment.
Who uses this standard
- Connector and accessory manufacturers designing low-voltage docking interfaces
- Battery and energy storage system (ESS) OEMs and integrators
- Test laboratories and certification bodies performing safety and environmental testing
- Vehicle manufacturers and design engineers developing removable-battery systems
