Musk hits out at Panasonic over Tesla battery supply

Thu, 04/18/2019 - 09:10 -- Hugh Finzel

Tesla CEO Elon Musk has blamed “lower-than-expected” battery manufacture from Panasonic for disrupting production of Tesla’s Model 3 electric vehicles (EVs).

Musk said in a post on Twitter that Panasonic’s battery cell lines at the ‘Gigafactory 1’ facility in Nevada amounted to about 24GWh per year— lower than the expected 35GWh— and had “been a constraint on Model 3 output since July (2018)”.

Musk added “Tesla won’t spend money on more capacity until existing lines get closer to 35GWh theoretical”.
