Tesla’s partner Panasonic to expand EV battery production in Japan

Published

on

As Tesla ramps up its production for the Model 3, one of its partners is also planning to increase production of electric vehicle batteries halfway around the world. According to the Japan Times, “Panasonic Corp. said Friday it will start manufacturing lithium-ion batteries for electric cars in fiscal 2019 at its plant in Himeji, Hyogo Prefecture, expanding domestic production to meet growing demand for green vehicles across the globe.”

It’s reported that, “Panasonic has been expanding its lithium-ion battery production both at home and abroad. The Japanese electronics maker supplies lithium-ion batteries to U.S. electric-car maker and energy company Tesla Inc., and the two companies also jointly run a plant in Nevada named Gigafactory that mass-produces the batteries.”

It turns out that Panasonic’s latest plant will be a factory conversion from LCD TV panel production to lithium-ion batteries for electric vehicles. “The Osaka-based electronics maker is likely to spend tens of billions of yen on setting up production lines there… [and] within Japan, Panasonic already has five other lithium-ion battery production plants.” Panasonic’s latest plans are aligned with recent efforts to pivot its business towards the auto sector.

Nasdaq (via Reuters) notes that, “Panasonic, the exclusive battery cell supplier for Tesla Inc’s mass-market Model 3, is reinventing itself as a provider of advanced auto parts to escape the price competition of smartphones and other lower-margin consumer products.” And Panasonic’s new direction is proving to be increasingly promising: “Panasonic sees batteries as a key driver for its plan to nearly double its automotive business revenue to 2.5 trillion yen ($22 billion) in the year through March 2022.”

And that’s not all — the company is also opening a new battery plant in Dalian, China. In addition to Tesla, it’s likely Panasonic’s new plants will service multiple automakers, especially in light of changes occurring in the world biggest auto market, China. Panasonic said in a statement: “The global market for eco-conscious vehicles has been growing… [leading to] increasing expectations from auto manufacturers on Panasonic, the leading manufacturer of automotive lithium-ion batteries.”

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 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:

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.
