MEASUREMENT OF HYDROGEN GAS EMISSION FROM BATTERY-POWERED PASSENGER CARS AND LIGHT TRUCKS DURING BATTERY CHARGING
- Ground Vehicle Standard
Gaseous emissions are measured in an enclosure during charging cycles at temperature extremes simulating garage charging at the manufacturer's recommended upper and lower operating limits of the battery under test.
To prevent damage of the battery under normal operating conditions due to ignition of gases within the battery by an external spark or flame, battery systems that are vented shall be equipped with a suitable flame arresting system. A flame arrestor may be provided either for each individual cell or at the outlet of a battery venting system.
Because certain failures in the charging system could cause gassing to be many times the normal rate, the measurement of hydrogen during the test should include appropriate abnormal conditions such as single point failures in the charging control subsystem.

The Electric Vehicle Forum Committee is intended to coordinate the development of standards for electric vehicles and supporting electric propulsion technologies such as batteries. In support of this goal, the Committee identifies areas where standards are needed, works with existing committees to develop such standards or modify existing standards where practical, and establishes subcommittees and/or task forces to prepare information reports, recommended practices or standards which are specific to electric vehicle. This Committee has included coordination of the development of standards for Hybrid-Electric Vehicles and Fuel Cells. International Cooperation: The committee or its subsidiary groups have formal liaison established with IEC TC69 (Electric Road Vehicles), for which SAE holds the International Administrative Secretariat, with Craig Toepfer of Ford as secretary and SAE Staff as Assistant Secretary, ISO TC22/SC21 with Gregory Nieminski of UL as U. S. TAG Chairman and SAE staff as U.S. TAG Administrator (Electric Road Vehicles), the Japanese Electric Vehicle Association (JEVA), and Battery Council International.
