Standards for flow batteries
In 2010, the organising committee for the first IFBF conference identified the need to develop standards to support the growing flow battery industry. As a result, several companies and individuals formed a CENELEC workshop and CWA 50611: Flow batteries – Guidance on the specification, installation and operation was published in …
