Tesla confirms ‘Powerpack 2’ with ‘twice the energy density’, says already delivered 300 MWh of Tesla batteries
Tesla decided to leave its new Powerpack out of its upcoming announcement for the solar roof and Powerwall 2.0 on Friday and instead confirmed the new battery pack in a blog tonight. As we reported in exclusivity earlier this month, the next generation Powerpack, now called ‘Powerpack 2’ by Tesla, features twice the energy capacity of the previous generation – 200 kWh.
Electrek has learned some details of Tesla’s ‘Powerpack 2.0’, the second generation of Tesla Energy’s scalable battery pack for commercial and utility-scale projects, which will be equipped with the new ‘2170’ battery cells. The new cell is potentially Tesla’s most important product to be unveiled this year – and yes, I’m aware Tesla unveiled the Model 3 in March.
Not much is known about Tesla’s new battery cell which was developed in partnership with Panasonic and that will soon go into production at the Gigafactory in Nevada. CEO Elon Musk and CTO JB Straubel both said that the new 2170 format cell will feature a new battery chemistry slightly different from the current 18650 cells used by Tesla in its vehicles and energy storage products.
