Lucas123 writes: German carmaker Daimler AG is building large battery storage systems for industrial use from the used lithium-ion batteries of its all-electric and hybrid vehicles. The first of Daimler's "2nd use battery storage units" will consist of 1,000 smart electric drive vehicle batteries and have a 13MWh of capacity. It is expected to be connected to the electrical grid in Lünen, Germany early next year. All of Daimler's battery storage units are currently planned to be greater than a megawatt in capacity, meaning they'll only be for commercial, not residential use, but the company said it does expect those batteries to be cost competitive with the ones Tesla announced earlier this year.
