The Energy Storage Systems Association is passionately committed to establishing energy storage as a sustainable part of renewable energy. Founded in 2012, the BVES now represents over 250 member companies worldwide, promotes quality standards for storage technologies and is involved at the political level. Together with its members, it strives for a decentralized, digitized and sustainable energy system. In order to also visually meet the requirements of the fast-growing, modern association, we have developed an expandable design system, which is characterized by lively modularity, prominent functionality and bold colors. We implemented the brand relaunch by re-designing the most important means of communication, including the trade fair appearance, various print media and the website.
