Panasonic slumps as Tesla branches out with new battery deal
Japanese battery maker Panasonic’s appears to be feeling the direct effects of its partnership with California-based electric car maker Tesla. Just recently, Panasonic opted to cut its profit outlook for 2019 over China’s slowing economy due to the trade war against the United States. Amidst these headwinds, Panasonic’s partnership with Tesla proved to be a silver lining for the Japanese company, pushing its battery business towards profitability — the first time in three quarters.
During a briefing about its adjusted forecasts, Panasonic Chief Financial Officer Hirokazu Umeda pointed out that there have been improvements with sales and profit on its battery business over the past months. Umeda notes that much of these improvements are due to its partnership with Tesla, especially considering the upgrades that Panasonic rolled out to its battery cell lines in Gigafactory 1. Overall, Tesla’s business gave Panasonic an operating profit of 16.5 billion yen (around $150M).
“Sales and profit at the Tesla business have improved,” Umeda said, later adding that additional lines at Gigafactory 1 would be installed by the end of March. The Panasonic CFO noted that with the upcoming improvements, Gigafactory 1’s total capacity could reach 35 GWh.
While its battery business appears to be thriving under its partnership with Tesla, Panasonic’s shares were walloped on Tuesday nonetheless. The Japanese firm’s 6.5% decline on Tuesday transpired amidst news that Tesla is acquiring ultracapacitor firm Maxwell Technologies in an all-stock deal valued at around $218 million. Considering that the opportunities presented by the Maxwell acquisition are related to Tesla’s battery technology, one could almost assume that Panasonic is practically losing its exclusivity as the electric car maker’s sole battery provider.
That said, industry analysts from Japan have noted that Panasonic’s recent decline in the market is primarily due to the company’s bleak quarterly earnings and annual profit estimate, which featured a 9% cut in its operating profit outlook and a decline of 19% for Q4 2018. This was a point highlighted by Masahiko Ishino, an analyst from the Tokai Tokyo Research Center, who noted in a statement to Reuters that Panasonic’s dive in the market was mostly due to the company’s outlook.
“The latest earnings have revealed how tough the situation is for Panasonic,” he said.
In a way, both Tesla and Panasonic appear to be branching out in their respective battery endeavors. Apart from acquiring Maxwell and its ultracapacitor tech, Tesla is also reportedly looking to partner with local battery suppliers in China for vehicles that will be produced at Gigafactory 3. On the other hand, Panasonic appears to be doing the same thing, recently teaming up with Toyota Motor Corp to collaborate in the development and production of rectangular-shaped prismatic batteries. Panasonic is also hoping to supply prismatic batteries to carmakers such as Honda, using the technology it would be developing with Toyota.
While these updates from Tesla and Panasonic might give the impression that the two companies are starting to diverge from each other, such an idea would be inaccurate. The batteries for Tesla’s electric cars and energy storage devices built in the US, after all, are still exclusively supplied by Panasonic. That means that the Japanese company would still be heavily invested in Tesla, as the electric car maker continues the Model 3 ramp and as it raises the production of its energy products like the Powerwall 2. Considering Tesla’s product roadmap, there is a very good chance that the electric car maker’s partnership with Panasonic would last for a long time to come.

Tesla inks multi-billion-dollar deal with LG Energy Solution to avoid tariff pressure
Tesla has reportedly secured a sizable partnership with LGES for LFP cells, and there’s an extra positive out of it.
Tesla has reportedly inked a multi-billion-dollar deal with LG Energy Solution in an effort to avoid tariff pressure and domesticate more of its supply chain.
Reuters is reporting that Tesla and LGES, a South Korean battery supplier of the automaker, signed a $4.3 billion deal for energy storage system batteries. The cells are going to be manufactured by LGES at its U.S. factory located in Michigan, the report indicates. The batteries will be the lithium iron phosphate, or LFP, chemistry.
Tesla delivers 384,000 vehicles in Q2 2025, deploys 9.6 GWh in energy storage
It is a move Tesla is making to avoid buying cells and parts from overseas as the Trump White House continues to use tariffs to prioritize domestic manufacturing.
LGES announced earlier today that it had signed a $4.3 billion contract to supply LFP cells over three years to a company, but it did not identify the customer, nor did the company state whether the batteries would be used in automotive or energy storage applications.
The deal is advantageous for both companies. Tesla is going to alleviate its reliance on battery cells that are built out of the country, so it’s going to be able to take some financial pressure off itself.
For LGES, the company has reported that it has experienced slowed demand for its cells in terms of automotive applications. It planned to offset this demand lag with more projects involving the cells in energy storage projects. This has been helped by the need for these systems at data centers used for AI.
During the Q1 Earnings Call, Tesla CFO Vaibhav Taneja confirmed that the company’s energy division had been impacted by the need to source cells from China-based suppliers. He went on to say that the company would work on “securing additional supply chain from non-China-based suppliers.”
It seems as if Tesla has managed to secure some of this needed domestic supply chain.

Tesla Shanghai Megafactory produces 1,000th Megapack for export to Europe
The Shanghai Megafactory was able to hit this milestone less than six months after it started producing the Megapack.
Tesla Energy has announced a fresh milestone for its newest Megapack factory. As per the electric vehicle maker, the Shanghai Megafactory has successfully produced its 1,000th Megapack battery.
The facility was able to hit this milestone less than six months after it started producing the grid-scale battery system.
New Tesla Megapack Milestone
As per Tesla Asia in a post on its official accounts on social media platform X, the 1,000th Megapack unit that was produced at the Shanghai Megafactory would be exported to Europe. As noted in a CNEV Post report, Tesla’s energy products are currently deployed in over 65 countries and regions globally. This allows Tesla Energy to compete in energy markets that are both emerging and mature.
To commemorate the 1,000th Megapack produced at the Shanghai Megafactory, the Tesla China team posted with the grid-scale battery with celebratory balloons that spelled “Megapack 1000.” The milestone was celebrated by Tesla enthusiasts on social media, especially since the Shanghai Megafactory only started its operations earlier this year.
Quick Megafactory Ramp
The Shanghai Megafactory, similar to Tesla’s other key facilities in China, was constructed quickly. The facility started its construction on May 23, 2024, and it was hailed as Tesla’s first entry storage project outside the United States. Less than a year later, on February 11, 2025, the Shanghai Megafactory officially started producing Megapack batteries. And by March 21, 2025, Tesla China noted that it had shipped the first batch of Megapack batteries from the Shanghai plant to foreign markets.
While the Shanghai Megafactory is still not at the same level of output as Tesla’s Lathrop Megafactory, which produces about 10,000 Megapacks per year, its ramp seems to be quite steady and quick. It would then not be surprising if Tesla China announces the Shanghai Megafactory’s 2,000th Megapack milestone in the coming months.

Tesla launches first Virtual Power Plant in UK – get paid to use solar
Tesla has launched its first-ever Virtual Power Plant program in the United Kingdom.
Tesla has launched its first-ever Virtual Power Plant program in the United Kingdom. This feature enables users of solar panels and energy storage systems to sell their excess energy back to the grid.
Tesla is utilizing Octopus Energy, a British renewable energy company that operates in multiple markets, including the UK, France, Germany, Italy, Spain, Australia, Japan, New Zealand, and the United States, as the provider for the VPP launch in the region.
The company states that those who enroll in the program can earn up to £300 per month.
Tesla has operated several VPP programs worldwide, most notably in California, Texas, Connecticut, and the U.S. territory of Puerto Rico. This is not the first time Tesla has operated a VPP outside the United States, as there are programs in Australia, Japan, and New Zealand.
This is its first in the UK:
Our first VPP in the UK
You can get paid to share your energy – store excess energy in your Powerwall & sell it back to the grid
You’re making £££ and the community is powered by clean energy

Tesla is not the only company that is working with Octopus Energy in the UK for the VPP, as it joins SolarEdge, GivEnergy, and Enphase as other companies that utilize the Octopus platform for their project operations.
It has been six years since Tesla launched its first VPP, as it started its first in Australia back in 2019. In 2024, Tesla paid out over $10 million to those participating in the program.
Participating in the VPP program that Tesla offers not only provides enrolled individuals with the opportunity to earn money, but it also contributes to grid stabilization by supporting local energy grids.
