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”.
Tesla is to acquire Maxwell Technologies, in a deal that values the California-based ultracapacitor firm at around US$218 million.
Maxwell said on 4 February the companies had entered into a definite merger agreement under which Tesla would buy the company's 45.9 million shares for $4.75 a share in an all-stock transaction. The deal represented a 55% premium to the share price, which closed at $3.07 on 1 February.
The merger is expected to be finalised in the second quarter of 2019 or shortly after, subject to the successful tender and exchange of shares, regulatory approvals and customary closing conditions.
A new grid-scale battery energy storage system has entered into service in Australia to bolster power grid security across five of the country’s six states.
The 30-megawatt/8-megawatt-hour lithium-ion BESS in South Australia is owned and developed by transmission provider Electranet— and is adjacent to the company’s Dalrymple substation.
The ‘ESCRI’ (Energy Storage for Commercial Renewable Integration) BESS comprises Samsung rechargeable batteries integrated via invertors, controller and transformers from power company ABB. The system has a 12-year design lifetime.
A lawsuit has been filed against Tesla in the US alleging that a “defective battery pack” led to a fatal car accident last year.
Chicago law firm Corboy & Demetrio has filed a product liability and negligence lawsuit, alleging that a 2014 Tesla S sedan “had a defective battery pack that caused the burning death of an 18-year-old passenger”.
Corboy & Demetrio partner Philip Corboy claimed: “The Tesla S battery was prone to extremely intense fires incapable of being timely extinguished.”
A 25MW/50MWh Tesla lithium-ion battery pack has entered service at the 60MW Gannawarra solar PV farm to create the first integrated solar and storage project in the state of Victoria, and the largest in Australia.
The Gannawarra battery— which was developed by Australian renewables company Edify Energy— is capable of powering more than 16,000 homes through two hours of peak demand. EnergyAustralia will operate the combined solar farm and battery facility.
