Battery Energy Efficiency

IEC 62282-6-300:2012 covers interchangeability of micro fuel cell (MFC) fuel cartridges to provide the cartridge compatibility for a variety of MFC power units while maintaining the safety and performance of MFC power systems. For this purpose, the standard covers fuel cartridges and their connector designs. Fuel type, fuel concentration and fuel quality are also covered. This standard also provides for the means to avoid the miss-connection of an improper fuel cartridge. Test methods for verifying the compliance with the interchangeability requirements for fuel and fuel cartridges are also provided in this standard. The main changes with respect to the previous edition are listed below:
- updates to Type A to D interchangeable connectors, addition of Type E;
- updates of the procedures, criteria and figures of the type tests for interchangeable connectors to ensure accurate and consistent results.

IEC 62282-6-200 specifies test methods for the performance evaluation of micro fuel cell power systems for laptop computers, mobile phones, personal digital assistants (PDAs), cordless home appliances, TV broadcast cameras, autonomous robots, etc. This new edition includes the following significant technical changes with respect to the previous edition:
- deletion of 5.3 (Fuel consumption test) as it was impractical to measure the actual consumption rate of some kinds of fuels;
- addition and modification of some terms and definitions.

IEC 62282-3-300:2012 provides minimum safety requirements for the installation of indoor and outdoor stationary fuel cell power systems in compliance with IEC 62282-3-100 and applies to the installation of the following systems:
- intended for electrical connection to mains directly or with a readily accessible, manually operable switch or circuit-breaker;
- intended for a stand-alone power distribution system;
- intended to provide AC or DC power;
- with or without the ability to recover useful heat.

IEC 62282-3-201 provides test methods for the electrical, thermal and environmental performance of small stationary fuel cell power systems that meet the following criteria:
- rated electric power output of less than 10 kW;
- grid-connected/independent operation or stand-alone operation with single-phase AC output or 3-phase AC output not exceeding 1 000 V, or DC output not exceeding 1 500 V;
- maximum allowable working pressure of less than 0,1 MPa (gauge) for the fuel and oxidant passages;
- gaseous fuel (natural gas, liquefied petroleum gas, propane, butane, hydrogen, etc.) or liquid fuel (kerosene, methanol, etc.);
- air as oxidant.
This document describes type tests and their test methods only. This document covers fuel cell power systems whose primary purpose is the production of electric power.
This new edition includes the following significant technical changes with respect to the previous edition: revision of test set-up, revision of measurement instruments, introduction of ramp-up test, introduction of rated operation cycle efficiency, introduction of electromagnetic compatibility (EMC) test, revision of exhaust gas test, introduction of typical durations of operation cycles.
