This part of IEC 62282 covers the interchangeability of power and data between micro fuel
cell power systems and electronic devices to provide the micro fuel cell power system
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.
