A project to repurpose used electric vehicle battery packs into energy storage systems is being developed by German vehicle OEM Audi and utility EnBW.
The project will focus on using second-life EV batteries from Audi with EnBW working on developing a stationary facility that stores power from its wind and photovoltaic parks.
The system aims to curb curtailment of renewable energy resources while offering services to municipal utilities, industrial companies or operators of decentralised generation plants.
The storage facility is due to be commissioned by the end of this year.
As a first step, the two partners are planning a storage facility on EnBW’s CHP plant in Heilbronn in order to test various application scenarios.
Arnim Wauschkuhn, responsible for stationary battery system solutions at EnBW, said: “The joint project takes into account the basic idea of harmonising security of supply and sustainability.”
The cooperation is part of Audi’s recycling commitment while providing energy storage systems for power grid applications.
