Stationary energy stores made from used electric vehicle batteries are of interest, however, not only for private domestic use. In larger configurations they are also suitable for industrial companies that want to cover their demand either partially or wholly with their own solar or wind energy systems. By bundling a large number of individual storage units, for example, peaks in consumption can be leveled out and energy costs significantly reduced. And when you start thinking on an even larger scale, completely new opportunities arise for the energy sector. By connecting a large number of storage units in series, the public grid can be stabilized, meaning that it would no longer be necessary to build expensive new power lines. Instead, further progress could be made in climate and environmental protection by buffering the green electricity from various sources in megawatt storage systems and feeding the power intelligently into the grid.
It makes far more ecological sense to give the batteries a "second life", which is the subject of intensive research at EVA's Heidemannstrasse premises in Munich. In its laboratory for new energy storage technologies, EVA Fahrzeugtechnik GmbH has already developed several prototypes that demonstrate how this "afterlife" could appear in practice.
