Mr. Doostdar, in the context of the energy transition, what exactly does Voltfang offer?
At Voltfang, we bring flexibility to the market by building sustainable energy storage systems for industry and commerce, as well as large-scale storage applications. We believe that battery storage systems are a key element of the energy transition. To make solar and wind power permanently and constantly available, we need huge numbers of storage systems in the grid – and Voltfang aims to provide a solution to this.
What are the biggest challenges you face when developing your systems?
There are two key challenges involved in developing the enclosures. The first is our customers’ specific requirements – whether the enclosure is to be installed indoors or outdoors, for example. The second relates to the technical requirements for the various battery modules. These need to be taken into account with a certain flexibility in terms of dimensioning, thermal technology and integration.
What role does climate control technology play in all this?
A pivotal one. During operation, the battery modules generate waste heat, which needs to be dissipated efficiently throughout the entire life cycle. This has an impact on both the cooling system and the entire thermal design of the systems. We are specifically working to safeguard the service life and efficiency of our systems.
How has Rittal supported you in developing your outdoor enclosures?
Rittal has provided us with active support for the thermal design, climate-control technology and AC connections. This has helped us develop a robust, efficient design that meets the high requirements in the field. The TopTec enclosures offer durability, corrosion protection and quality, so they’re the perfect choice for us.
What aspects of your partnership with Rittal are particularly important to you?
Right from the start, we were looking for a high-quality partner for Voltfang, with a view to a really long-term collaboration. As a start-up, which is now developing into a scale-up, we need a partner who understands us and can provide us with support – especially technical support – over the next five to ten years. In Rittal, we have found the perfect match.
