Overview
IEC 62282-6-401:2025 is an international standard developed by the International Electrotechnical Commission (IEC) that specifies performance test methods for micro fuel cell power systems used in laptop computers. This part of the IEC 62282 series focuses on fuel cell/battery hybrid power systems that integrate a micro fuel cell with a secondary battery, specifically designed for portable computing applications. The standard emphasizes electrical performance evaluation, power and data interchangeability between the fuel cell system and the laptop, and characteristics related to the balance of plant (BOP) components relevant to these systems.
This standard applies to various types of fuel cell power packs including gaseous hydrogen-fueled, liquid hydrogen-fueled, and direct methanol fuel cells combined with battery hybrid systems. It excludes reformer-equipped fuel cell power systems.
