After it was founded in 1985, the EHC Bregenzerwald played in the Vorarlberg regional class and in hobby leagues. In the 1998/99 season, the Vorarlberg regional champions were promoted to the regional league, and the Vorarlbergs have been playing in the national league since the league was redistributed before the 2001/02 season . The greatest success up to that point - participation in the semi-finals - came in the 2002/03 season .
The EHCBW was the last club in the National League in Austria that played in an open-air arena until the 2011/12 season. The “crater”, as the arena was jokingly called by opposing fans, has stumbled many a great team. The disadvantage was that when it snowed in the Bregenzerwald, the playability of the ice surface was often not guaranteed. Ice masters and helpers had to spend a lot of time to keep the game going in deep winter. When the Alberschwende arena was closed in 2012, in cooperation with the city of Dornbirn and the Dornbirn EC, the opportunity was found to handle the 2012/13 season in the Dornbirn exhibition stadium.
After starting difficulties at the beginning of the 2012/13 season , the EHC Bregenzerwald played a successful regular season and was the only team from Vorarlberg to reach the play-offs. In the semi-finals of these play-offs, the EHC defeated EK Zell am See in the best-of-five series with 3: 2 and thus reached the INL final. There, the EHC Bregenzerwald defeated HK Slavija Ljubljana in the best-of-five series, also 3-2, which was the greatest success in the club's history. The success was repeated in the 2015/16 season .
In 2016 the association was renamed EC Bregenzerwald .
