Nissan and Eaton have announced a partnership that will use their respective expertise in lithium-ion batteries and power electronics to create commercially viable energy storage and control centers that offer a productive second life for Nissanâ€™s EV batteries after their days on the road.
The two companies will deploy a module that combines retired LEAF batteries with Eatonâ€™s uninterruptable power supply (UPS) technology and solar PV to create a stand-alone energy storage and control package that can be used connected to, or independent of, the grid.
A recent DOE analysis found that repurposing used EV batteries for stationary storage can offset the costs of recycling vehicles. Navigant Research predicts that second-life batteries will represent a $3 billion business by 2035.
â€œThese systems will really facilitate the wider adoption and deployment of renewable generation, giving people greater control over their energy supply and consumption,â€ said Eaton VP of Marketing Cyrille Brisson. â€œThe benefits of such a unit include continuity of supply, increased grid stability and efficiency, avoidance of peak energy tariffs and reduced reliance on expensive fuels like diesel in no-grid or poor-grid situations.â€
