Tesla won’t be making 10kWh Powerwalls–it’s 7kWh batteries only, for now
- sunstone 11y agoprediction - Tesla will be making 10kWh Powerwalls for solar storage after the refresh this summer.
- Someone1234 11y agoI'd recommend reading the article in this case. They make a very good argument for why the 10 kWh version was inferior to the 7 kWh version. I guess the larger one used a different type of battery?
- mattdeboard 11y agoYes right at the top of the article it describes the chemical differences.
- ChuckMcM 11y agoInteresting that they are not using a Lithium chemistry battery in these. I was thinking they were just repackaging variants on the Model S battery pack. Seems like a pretty simple plan to create an outer casing that hangs on the wall for a "half pack" (35KWh?) from the 70KWh battery pack. Perhaps they are getting better margins selling them attached to cars.
- plorg 11y agoMaybe this is an opportunity to test out different battery chemistries that may initially move into their cars. Alternately, the magnesium chemistry could be cheaper than lithium but less energy-dense, hence not a great choice for the cars. Or it could be inappropriate for vehicle use for a number of reasons including safety, cycle lifespan, etc.
