ECO STOR residential second-life EV battery storage
Published 7 July 2022; updated 30 September 2026; 3-minute read. ECO STOR’s residential energy-storage system repurposes used EV batteries for private homes, particularly homes with rooftop solar. The article says a battery is replaced once its capacity falls below 70%, although it may have 10–15 years of remaining life for less demanding storage use.
The system reuses the complete battery without disassembly/reassembly or new wiring/electronics, while maintaining automotive handling standards. A proprietary method diagnoses battery health, then a control unit links the battery to the home’s energy system. Households can store solar power for peak demand, reduce exposure to high electricity prices, and charge their EVs from home-generated power. The wall-mounted casing is described as designed to be discreet.
The company says the system lowers the cost of small-scale storage and battery lifecycle carbon emissions, supports renewable-energy use, reduces demand for new battery production, and facilitates recycling once batteries are spent. Article market context includes a global battery-storage market forecast of USD 8.54 billion by 2023, a historical projection. The page quotes ECO STOR staff describing high electricity prices and subsidies as market drivers.
ECO STOR had signed an MoU with Nissan, Norsk Gjenvinning and Agder Energi on EV battery reuse and recycling, and established German subsidiary ECO STOR GmbH for grid-connected systems using new batteries.
