Recycling EV Batteries More Cost-Competitive Than Using For Home Energy Storage - Lux Research Echoes Tesla CTO JB Straubel

It makes more sense from an economic standpoint to recycle old plug-in electric vehicle batteries than to reuse them directly for home energy storage, according to a new report from Lux Research. The primary reason? According to Lux Research, reused plug-in electric vehicle batteries will “deliver questionable returns on account of reduced performance, limiting them to application with less frequent and shallower depth of discharge cycles.” This echoes what Tesla CTO JB Straubel said earlier this year. Tesla has said repeatedly... [Lire la suite]

Tesla Model S battery pack data shows very little capacity loss over high mileage

‘Lithium’ battery capacity degradation is one of the main concerns of electric vehicle buyers and potential buyers. Since the resurgence of electric cars is relatively recent, meaningful long-term data on large battery packs is fairly rare. Only Tesla has battery packs with a capacity higher than 30 kWh on the road in any significant number and they only have been in operation for a few years (Roadster aside). But a few Tesla owners have accumulated impressive mileage on their vehicles and the data provides an interesting... [Lire la suite]

Bosch cooperates with BMW and Vattenfall on a second life electric vehicles batteries project

What to do with valuable batteries once they have reached the end of   their life cycle in electric vehicles? A project involving three partners is connecting old batteries in Hamburg to form a large-scale storage  system to keep the power grid stable. Lithium-ion batteries still have high storage capacity at the end of their life cycle in electric vehicles. As a result, they are still very valuable and can be used extremely efficiently as stationary buffer storage for many years to come. The project allows the three... [Lire la suite]
