Reports suggest that Tesla’s Powerpack 2.0 and next generation Powerwall will come equipped with 2170 battery cells that could double the capacity of this modular unit and change the face of commercial and utility energy storage and management.

The Powerpack has proved a smash hit with utilities companies and recent deals with the Irvine Ranch Water District, the California Public Utilities Commission and Morgan Stanley have proven the technology and this step up to a denser battery pack could be a seminal moment in Tesla’s history.

We’ve considered the fact that this could actually be Tesla’s golden goose, especially when it’s combined with more efficient SolarCity panels that could help utilities companies and large corporations slash their energy bills and their carbon footprint for years to come.

Different chemistry is the key

Electrek has revealed some early details, namely the 2170 format cell that boasts a different battery chemistry to the 18650 cells that the company uses in its car batteries and current Powerpack. That should give the Powerpack 2.0 a capacity of approximately 200kWh without any significant increase in size.

Tesla will fit its own in-house inverter, too, after working hard on the price point to lower the cost to the customer by 19%. It also slashed the cost of Powerpack and this could go on to be a potent force in the energy storage market. The Department of Energy wanted clean power storage systems like this by 2050, but if Tesla can take a leap forward with the new cells and bring a potent solar panel on board then this could change the whole game.

There is no obvious reason why these cells can’t slot into the cars, too, which could have a serious impact on the range and power of the vehicles. There’s no word yet, though, on when that might happen.
