Tesla battery supplier Panasonic to increase battery production at Giga Nevada
Tesla battery supplier Panasonic is accelerating plans to increase battery cell production at Gigafactory Nevada. Increasing battery production at Giga Nevada would likely help Tesla increase its vehicle production capacity and benefit from the Inflation Reduction Act’s (IRA) electric vehicle (EV) tax credits.
An executive from Panasonic shared that Tesla approached the Asian battery supplier about battery supply. Tesla told Panasonic it would buy as many battery cells as Panasonic could make.
Tesla has made similar public statements in the past, emphasizing that its 4680 production lines would not disrupt any cell supply relations with other battery suppliers. Elon Musk and other Tesla executives have always been clear that the company would still buy battery cells from its partners, including LG Energy Solutions, Panasonic, and CATL in China.
In response to Tesla’s statement, Panasonic decided to install an additional production line at Gigafactory Nevada, sources told Nikkei Asia. The executive who shared information on the matter added that Giga Nevada is “already crammed,” explaining why only one battery cell production line is being added.
Potential Impact of Tesla and Panasonic’s Battery Production
The new cell production line is expected to begin operation in a year or two. It’s estimated to increase Tesla Giga Nevada’s annual production capacity by about 10% from 38 GWh to 39 GWh. At 39 GWh, Giga Nevada would produce enough battery cells for Tesla to manufacture between 500,000 to 700,000 Tesla Model 3 vehicles.
Tesla isn’t the only EV automaker investing in battery cell production. The Inflation Reduction Act’s EV credits for domestic cell production have encouraged more automakers and foreign battery suppliers to build battery plants in the United States.
In the Q4 2022 earnings call, Elon Musk commented that the IRA’s credits for domestic manufacturing could make significant contributions in the future.
“Long term, we expect these–the value of these credits to be very significant,” said Musk. “And in the case of Panasonic domestic manufacturing, we’re splitting the value of the credits. So it will–the value of credits this year will not be gigantic, but I think it could be gigantic.
Zack Kirkhorn shared a bit more about Tesla’s estimates regarding the IRA’s credits related to battery composition.
“So different products, we think, will get different amounts of credit. The regulations here are still in flux and there continues to be updates, so this is just our best understanding at the moment. But we think on the order of $150 million to $250 million per quarter this year and growing over the course of the year as our volumes grow,” Kirkhorn said.
Kirkhorn concluded that the IRA’s credits could eventually impact the affordability of some electric vehicles.
Panasonic’s Future in the United States
Besides Tesla, Panasonic might start working with Stellantis and BMW on new battery plants in North America. The Japanese battery supplier already selected Kansas as the site for a 4680 plant.
“We were concentrating on Kansas and developing the new [4680] battery, but the IRA turned the tide. Tesla started saying to prioritize batteries that we can quickly increase in quantity,” said the Panasonic executive.
Panasonic shifted its plans for the Kansas facility. It will produce 2170 battery cells in Kansas as well, along with 4680 cells. Sources state that the Asian battery supplier will focus on making 2170 cells in Kansas because they are “a few months faster to supply.”

A Tesla Semi was involved in a fatal collision on U.S. Highway 50 in Dayton, Nevada, on Sunday, June 28, 2026, marking the first known fatal crash involving the electric Class 8 truck. The incident occurred around 7:20 a.m. at the intersection with Traditions Parkway, approximately 40 miles east of Reno and close to Tesla’s Gigafactory Nevada.
According to the Lyon County Sheriff’s Office and the Nevada State Police Highway Patrol, a semi-truck struck two passenger vehicles stopped at a traffic signal. The truck hit the vehicles from behind. Two people were pronounced dead at the scene, and a third person suffered life-threatening injuries and was flown to a hospital, Forbes reported.
Preliminary statements gathered at the scene by the Lyon County Sheriff’s Office suggested the truck driver may have fallen asleep at the wheel. However, the Nevada Highway Patrol, which is leading the investigation, stated that the official cause has not yet been determined.
Additional information is expected to be released early the following week. The truck was seized for evidence as part of the ongoing probe.
Responders at the scene included deputies from the Lyon County Sheriff’s Office, personnel from the Nevada Highway Patrol, Central Lyon County Fire Department, and the Nevada Department of Transportation. The crash led to the temporary closure of U.S. 50 in both directions.
The Tesla Semi is Tesla’s battery-electric heavy-duty truck, produced at the nearby Gigafactory in Nevada. Authorities initially described the vehicle as a semi-truck; its make was subsequently confirmed through reporting and scene identification; an interesting bit of information here, as the Semi is not yet available publicly and many do not know that Tesla builds electric trucks.
The investigation remains active, with no further official details on contributing factors or vehicle systems released as of early July 2026.
This incident highlights ongoing scrutiny of commercial vehicle safety on Nevada highways, particularly involving fatigue. Law enforcement continues to gather evidence and witness statements.
Tesla has expanded its Robotaxi program to Miami, Florida, marking the third state the autonomous ride-hailing platform has made its way to since launching last Summer.
Tesla announced today that the Robotaxi suite would now officially launch rides in a geofence in Miami:

The first geofence in Miami covers approximately 10 to 14 square miles. The area appears to be focused on western and central Miami, including Miami International Airport (MIA). It also includes popular routes like SR 826 (Palmetto Expressway), US 41 (Tamiami Trail), and connectors such as SR 968, 953, 959, and 972.
This is Tesla’s initial Miami launch zone, smaller and more targeted than some competitors’ areas (for example, Waymo’s initial rollout was broader in eastern neighborhoods). It prioritizes high-traffic, airport-linked routes before wider expansion.
The expansion is a huge signal for Tesla that it is now operating in Florida, a heavy-traffic state with many tourist areas, including Fort Lauderdale, Palm Beach, and the Boynton area, all of which are coastal and will attract perhaps millions of tourists in any given year.
¿Qué lo que Miami?

The Tesla Robotaxi network launched last year on June 22, in Austin, Texas, beginning limited commercial operations in that city. It expanded shortly thereafter into the San Francisco Bay Area of California in late July 2025, marking entry into a second state with service covering key areas such as San Francisco, San Jose, and Berkeley.
Full commercial service was achieved in Austin by November 18, 2025, strengthening its presence within Texas before further growth.
In 2026, the network continued expanding across Texas with the addition of Dallas and Houston on April 18, significantly broadening its footprint in the state. This new launch into Miami marks Tesla entering a new state and bringing active locations to include Austin, Dallas, Houston, San Antonio in Texas, and the Bay Area in California.
These sequential expansions have steadily increased the network’s reach across major metropolitan areas in Texas, California, and Florida, focusing on scaling operations city by city and state by state since the initial Austin debut.
Tesla CEO Elon Musk has tempered expectations for the company’s humanoid robot Optimus, emphasizing that initial production will ramp up slowly despite recent progress on the manufacturing line. In a July 1 reply on X, Musk responded to optimistic community speculation by stating, “No, Optimus production will be extremely slow at first, as everything is new. This is not like making a car.”

The comment came in response to a post theorizing that Tesla had accelerated Optimus V3 development and might soon unveil an impressive demonstration with multiple units already in meaningful production. Musk’s clarification highlights the fundamental differences between scaling a novel humanoid robot and Tesla’s established automotive operations, which benefit from over a century of refined supply chains, tooling, and processes.
Recent updates show tangible advancement. Musk shared a photo of himself walking the Optimus production line at Fremont, where Tesla is converting former Model S/X manufacturing space. According to Q1 2026 earnings commentary, limited production is slated to begin in late July or August 2026 on this converted line.
Tesla Optimus project fires up as Musk sees production line progress
Musk previously noted that Optimus features roughly 10,000 unique parts, making early output rates “literally impossible to predict” and describing them as “quite slow.” A larger dedicated factory at Giga Texas is under construction, targeting higher-volume production around summer 2027 with long-term annual capacity potentially reaching millions of units.
Some experts point out that pioneering humanoid robotics demands inventing new automation techniques, actuator supply chains, and quality-control standards in real time. Unlike vehicles, where components and assembly methods are mature, every element of Optimus—from dexterous hands to AI-integrated movement—requires fresh engineering solutions. Early units are expected to handle simple factory tasks before expanding to more complex roles.
This cautious approach aligns with Tesla’s history of under-promising and over-delivering on complex technologies. While enthusiasts hoped for rapid deployment, Musk’s message underscores a deliberate strategy: prioritize reliability and iterative improvement over rushed volume.
Analysts suggest the S-curve ramp typical of new manufacturing will eventually accelerate once foundational issues are resolved, positioning Optimus as a potential trillion-dollar product line.
Musk has long envisioned Optimus transforming labor markets, assisting in homes, factories, and hazardous environments. By setting realistic timelines, Tesla aims to build sustainable momentum rather than risk disappointment. As the Fremont line comes online this summer, investors and fans will watch closely for the first production metrics and capability demonstrations.
