Tesla patents custom cooling system for longer-lasting energy storage devices
A significant part of Tesla’s business relies heavily on the durability and longevity of its battery packs, and in the spirit of disruptive innovation, the Silicon Valley-based company has continued to make improvements to its battery technology to make them more durable and more efficient. Tesla was able to achieve this through several ways, one of which was discussed in a recently published patent application.
It is pertinent for battery packs, particularly those that are used for energy storage, to be robust enough that they last for a very long time. To accomplish this, battery packs must be able to handle multiple charge and discharge cycles on a regular basis. They must also be able to weather faults in the system, including those that may cause damage to the actual cells in the pack itself.
Such a system was outlined by Tesla in a patent simply titled “Energy Storage System.” Explaining its rationale, the Silicon Valley-based company stated that “cells and other components in a pack generate heat during operation, both during the charging process to store the energy and during the discharge process when energy is consumed.” Tesla further explains that “when the cells fail, they typically release hot gases. These gases may impact the integrity of other cells in the pack and may cause substantial damage to the functional cells which have not failed.”
With this in mind, Tesla maintains that there is a need to develop an “improved energy storage system” that will be capable of reducing or removing “one or more of the issues mentioned.” Tesla’s patent describes two strategies that could improve its battery packs. One of these involves the use of a novel system that utilizes a cold plate, which could help remove heat generated by the battery pack during use. Heat pipes may also be used together with a cold plate to achieve this purpose.
“In certain embodiments, a cold plate (which provides liquid cooling) may be in thermal connection with the battery cells 100 to further remove heat generated during system use. The cold plate may be in direct thermal contact with the battery cells 100 or, alternatively, one or more layers and/or features may be between the cold plate and the battery cells 100. In certain embodiments, the battery cells 100 are in contact with one or more heat pipes to remove excess heat disposed under the battery cells. A cold plate is disposed below the heat pipe or pipes (on the side of the heat pipe away from the battery cells 100) that helps dissipate the heat contained in the heat pipe.”
“In certain embodiments, the cold plate may be in thermal contact with one side of the cells without any heat pipes disposed between the cells. The cold plate may physically consist of a single plate or multiple plates that are thermally connected to the cells and/or one another. In other embodiments, one or more heat pipes are disposed between the battery cells 100 and a cold plate is disposed below the battery cells 100. The heat pipes and the cold plate may be in thermal connection with one another.”
Apart from the use of cold plates, Tesla also described a battery pack with regions that are designed to give way when mechanical failures happen. By using such a system, the majority of the cells in a battery pack become protected even if some cells were to fail.
“The top plate includes one or more weak areas above the one or more battery cell. The weak areas are regions that have less integrity and thus, where mechanical failure is more likely to occur if a battery cell releases gas. These regions may be physically weaker areas compared to the surrounding areas and may rupture when pressure builds up due to a failed cell. Alternatively, the weak areas may be chemically weaker and preferentially rupture when exposed to the caustic gases released by a failed battery cell. The weak areas may also fail due to a combination of physical and chemical weakening.”

Tesla’s focus on battery integrity in its recently published patent application suggests that the Silicon Valley-based company is looking to develop packs that are capable of lasting a very long time. Such improvements have been teased before, especially in a paper released by Tesla lead battery researcher Jeff Dahn and members of the Department of Physics and Atmospheric Science at Dalhousie University. The cells described in the paper are capable of lasting over 1 million miles on the road, or 20 years if used in grid energy storage.
Looking at these initiatives, as well as the battery pack contingencies outlined in the recently released patent, it appears that Tesla is building up towards creating an ecosystem of products that are capable of lasting decades. This, of course, plays a huge part in pushing Tesla’s overall goal of accelerating the advent of sustainable energy.

Tesla Powerwall distribution expands in Australia
Inventory is expected to arrive in late February and official sales are expected to start mid-March 2026.
Supply Partners Group has secured a distribution agreement for the Tesla Powerwall in Australia, with inventory expected to arrive in late February and official sales beginning in mid-March 2026.
Under the new agreement, Supply Partners will distribute Tesla Powerwall units and related accessories across its national footprint, as noted in an ecogeneration report. The company said the addition strengthens its position as a distributor focused on premium, established brands.
“We are proud to officially welcome Tesla Powerwall into the Supply Partners portfolio,” Lliam Ricketts, Co-Founder and Director of Innovation at Supply Partners Group, stated.
“Tesla sets a high bar, and we’ve worked hard to earn the opportunity to represent a brand that customers actively ask for. This partnership reflects the strength of our logistics, technical services and customer experience, and it’s a win for installers who want premium options they can trust.”
Supply Partners noted that initial Tesla Powerwall stock will be warehoused locally before full commercial rollout in March. The distributor stated that the timing aligns with renewed growth momentum for the Powerwall, supported by competitive installer pricing, consumer rebates, and continued product and software updates.
“Powerwall is already a category-defining product, and what’s ahead makes it even more compelling,” Ricketts stated. “As pricing sharpens and capability expands, we see a clear runway for installers to confidently spec Powerwall for premium residential installs, backed by Supply Partners’ national distribution footprint and service model.”
Supply Partners noted that a joint go-to-market launch is planned, including Tesla-led training for its sales and technical teams to support installers during the home battery system’s domestic rollout.

Tesla Megapack Megafactory in Texas advances with major property sale
Stream Realty Partners announced the sale of Buildings 9 and 10 at the Empire West industrial park, which total 1,655,523 square feet.
Tesla’s planned Megapack factory in Brookshire, Texas has taken a significant step forward, as two massive industrial buildings fully leased to the company were sold to an institutional investor.
In a press release, Stream Realty Partners announced the sale of Buildings 9 and 10 at the Empire West industrial park, which total 1,655,523 square feet. The properties are 100% leased to Tesla under a long-term agreement and were acquired by BGO on behalf of an institutional investor.
The two facilities, located at 100 Empire Boulevard in Brookshire, Texas, will serve as Tesla’s new Megafactory dedicated to manufacturing Megapack battery systems.
According to local filings previously reported, Tesla plans to invest nearly $200 million into the site. The investment includes approximately $44 million in facility upgrades such as electrical, utility, and HVAC improvements, along with roughly $150 million in manufacturing equipment.
Building 9, spanning roughly 1 million square feet, will function as the primary manufacturing floor where Megapacks are assembled. Building 10, covering approximately 600,000 square feet, will be dedicated to warehousing and logistics operations, supporting storage and distribution of completed battery systems.
Waller County Commissioners have approved a 10-year tax abatement agreement with Tesla, offering up to a 60% property-tax reduction if the company meets hiring and investment targets. Tesla has committed to employing at least 375 people by the end of 2026, increasing to 1,500 by the end of 2028, as noted in an Austin County News Online report.
The Brookshire Megafactory will complement Tesla’s Lathrop Megafactory in California and expand U.S. production capacity for the utility-scale energy storage unit. Megapacks are designed to support grid stabilization and renewable-energy integration, a segment that has become one of Tesla’s fastest-growing businesses.

Tesla meets Giga New York’s Buffalo job target amid political pressures
Giga New York reported more than 3,460 statewide jobs at the end of 2025, meeting the benchmark tied to its dollar-a-year lease.
Tesla has surpassed its job commitments at Giga New York in Buffalo, easing pressure from lawmakers who threatened the company with fines, subsidy clawbacks, and dealership license revocations last year.
The company reported more than 3,460 statewide jobs at the end of 2025, meeting the benchmark tied to its dollar-a-year lease at the state-built facility.
As per an employment report reviewed by local media, Tesla employed 2,399 full-time workers at Gigafactory New York and 1,060 additional employees across the state at the end of 2025. Part-time roles pushed the total headcount of Tesla’s New York staff above the 3,460-job target.
The gains stemmed in part from a new Long Island service center, a Buffalo warehouse, and additional showrooms in White Plains and Staten Island. Tesla also said it has invested $350 million in supercomputing infrastructure at the site and has begun manufacturing solar panels.
Empire State Development CEO Hope Knight said the agency was “very happy” with Giga New York’s progress, as noted in a WXXI report. The current lease runs through 2029, and negotiations over updated terms have included potential adjustments to job requirements and future rent payments.
Some lawmakers remain skeptical, however. Assemblymember Pat Burke questioned whether the reported job figures have been fully verified. State Sen. Patricia Fahy has also continued to sponsor legislation that would revoke Tesla’s company-owned dealership licenses in New York. John Kaehny of Reinvent Albany has argued that the project has not delivered the manufacturing impact originally promised as well.
Knight, for her part, maintained that Empire State Development has been making the best of a difficult situation.
“(Empire State Development) has tried to make the best of a very difficult situation. There hasn’t been another use that has come forward that would replace this one, and so to the extent that we’re in this place, the fact that 2,000 families at (Giga New York) are being supported through the activity of this employer. It’s the best that we can have happen,” the CEO noted.
