General Motors Repurposes Chevrolet Volt Batteries For Energy Storage
Having already recycled battery covers into animal habitats, General Motors is turning its efforts toward the Chevrolet Volt’s batteries themselves.
General Motors battery life cycle boss Pablo Valencia says the packs used in the PHEV can still be of use in storage applications once its days providing energy to the vehicle draws to an end, “delivering waste reduction and economic benefits on an industrial scale” in repurposing.
To demonstrate this, five packs from the first-gen Volt are working in concert with a 74-kilowatt solar array and two wind turbines — each good for 2 kW — to generate power at GM’s Enterprise Data Center at the Milford Proving Ground in Milford, Mich. The packs can also provide emergency power for four hours in the event of a power outage, while the full setup can deliver up to 100 MWh of energy — the equivalent of the amount used by 12 average households — annually to the data center, with excess sent to the proving ground’s grid.
Though supply of Volt packs remains low for now, GM says it’s working with partners to “validate and test systems for other commercial and non-commercial uses.” Valencia adds the repurposing of packs for energy storage would be perfect for commercial use, providing “full functionality” from the packs while also reducing upfront costs in implementing the system.
