Overview

EN IEC 62282-6-400:2019 - Fuel cell technologies, Part 6-400 - defines power and data interchangeability for micro fuel cell power systems. It establishes requirements to make micro fuel cell power units compatible with a variety of electronic devices while maintaining safety and performance. The standard applies to wearable or hand‑carried micro fuel cell systems that provide DC outputs up to 60 V and power outputs up to 240 VA, and it addresses both physical interfaces and electronic control/communication between the fuel cell system and the host device.

Key topics and technical requirements

• Power interface and connector configuration
  • Defines connector types and wiring for use as battery replacements, external power sources (AC‑adapter style), or semi‑integrated modules.
• Power management circuitry and power sharing
  • Specifies requirements for internal/external battery hybridization, power sharing strategies and how a micro fuel cell can supplement or replace batteries while protecting device operation.
• Data communication protocol and specification
  • Describes the data link, message types and data fields to exchange status, control and diagnostics between the micro fuel cell power system and the electronic device.
• Modes of operation and alerts
  • Standardizes operation modes (Power‑OFF, Battery mode, Start‑up, Idle, Power‑ON, Hybrid, etc.) and alert conditions required to meet device power control expectations.
• Definitions and system classification
  • Classifies micro fuel cell systems as integrated, semi‑integrated or stand‑alone and provides related terminology (see IEC TS 62282‑1).

Applications and practical value

• Enables interoperability between micro fuel cell power systems and consumer electronics (smartphones, tablets, cameras, portable PCs, wearable devices).
• Supports manufacturers and OEMs in designing battery replacement modules, external fuel cell chargers, and hybrid power packs that communicate status and control with host devices.
• Useful for product design, interoperability testing, regulatory compliance and safety assessments where predictable power behavior and standardized data exchange are required.
• Facilitates aftermarket solutions and accessory ecosystems by standardizing connector and protocol expectations.

Who should use this standard

• Fuel cell system designers and OEMs
• Electronic device manufacturers and integrators
• Connector and power electronics designers
• Test laboratories and conformity assessors
• Standards and regulatory engineers evaluating portable power solutions

Related standards

• IEC TS 62282-1 (Terminology) - normative reference for terms and definitions
• Harmonized documents referenced in the norm: EN IEC 62282-6-100, EN IEC 62282-6-200, EN IEC 62684 (as noted in the standard’s bibliography)

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC
Publication(s)"). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

compatibility for a variety of electronic devices while maintaining the safety and performance
of the micro fuel cell system. For that purpose, this document covers power interfaces and
their connector configuration. The power management circuitry and power sharing
methodology are also provided.
This document also covers the data communication protocol and its data specification.
Operation modes and alert conditions are also provided for the means to comply with the
power control requirements of the electronic device.
A micro fuel cell power system and micro fuel cell power unit block diagram is shown in
Figure 1. Micro fuel cell power systems and micro fuel cell power units are defined as devices
that are wearable or easily carried by hand, providing DC outputs that do not exceed 60 V DC
and power outputs that do not exceed 240 VA. This document covers the power and data
interfaces between the micro fuel cell power unit and electronic device.
