Last July, a Tesla Megapack in the 300MW/450MWh Victoria Big Battery caught fire while it was being tested. The fire spread to another battery, resulting in two Megapacks in the installation being destroyed. An investigation into the incident was promptly initiated a few days later. 

The results of the investigation have now been made public. According to a technical report written by experts at Fisher Engineering and the Energy Safety Response Group (ESRG), the Victoria fire last July was caused by a liquid coolant leak, which caused arcing within the Megapack’s battery modules. 

“The most likely root cause of the fire was a leak within the liquid cooling system of MP-1 causing arcing in the power electronics of the Megapack’s battery modules. This resulted in heating of the battery module’s lithium-ion cells that led to a propagating thermal runaway event and the fire,” the report read. 

Personnel in the area initially noticed smoke emanating from one Megapack battery at around 10 a.m. on July 30. Emergency crews were called, and once they arrived, a perimeter was established around the battery storage unit. Water was applied to the Megapack, but the flames spread to a neighboring battery unit anyway.

Fortunately, the spread of the blaze stopped there, and the fire burned itself out over a six-hour period. The results of the incident were in line with Tesla’s guidance for such incidents, which advises emergency responders to allow Megapacks that have caught fire to burn themselves out. The incident was ultimately dubbed a “safe failure,” according to a report from Energy Storage News. 

It should be noted that the Megapack that started the fire had been manually disconnected from a number of monitoring, control, and data collection systems because it was undergoing testing at the time of the incident. Wind speeds at the time also contributed to the spread of the blaze. 

Tesla, for its part, has implemented a number of procedural, firmware, and hardware mitigations to avoid similar incidents from happening in the future. These include improved coolant system inspections during Megapack assembly, additional alarms to the coolant system’s telemetry data to identify and respond to a possible coolant leak, and the installation of newly designed, thermally insulated steel vent shields within the thermal roof of all Megapacks, among others. 

The results of the Victoria Megapack fire’s investigation could be viewed below.

Starlink terminals smuggled into Iran amid protest crackdown: report

Roughly 6,000 units were delivered following January’s unrest.

The United States quietly moved thousands of Starlink terminals into Iran after authorities imposed internet shutdowns as part of its crackdown on protests, as per information shared by U.S. officials to The Wall Street Journal

Roughly 6,000 units were delivered following January’s unrest, marking the first known instance of Washington directly supplying the satellite systems inside the country.

Iran’s government significantly restricted online access as demonstrations spread across the country earlier this year. In response, the U.S. purchased nearly 7,000 Starlink terminals in recent months, with most acquisitions occurring in January. Officials stated that funding was reallocated from other internet access initiatives to support the satellite deployment.

President Donald Trump was aware of the effort, though it remains unclear whether he personally authorized it. The White House has not issued a comment about the matter publicly.

Possession of a Starlink terminal is illegal under Iranian law and can result in significant prison time. Despite this, the WSJ estimated that tens of thousands of residents still rely on the satellite service to bypass state controls. Authorities have reportedly conducted inspections of private homes and rooftops to locate unauthorized equipment.

Earlier this year, Trump and Elon Musk discussed maintaining Starlink access for Iranians during the unrest. Tehran has repeatedly accused Washington of encouraging dissent, though U.S. officials have mostly denied the allegations.

The decision to prioritize Starlink sparked internal debate within U.S. agencies. Some officials argued that shifting resources away from Virtual Private Networks (VPNs) could weaken broader internet access efforts. VPNs had previously played a major role in keeping Iranians connected during earlier protest waves, though VPNs are not effective when the actual internet gets cut.

According to State Department figures, about 30 million Iranians used U.S.-funded VPN services during demonstrations in 2022. During a near-total blackout in June 2025, roughly one-fifth of users were still able to access limited connectivity through VPN tools.

Critics have argued that satellite access without VPN protection may expose users to geolocation risks. After funds were redirected to acquire Starlink equipment, support reportedly lapsed for two of five VPN providers operating in Iran.

A State Department official has stated that the U.S. continues to back multiple technologies,  including VPNs alongside Starlink, to sustain people’s internet access amidst the government’s shutdowns.

Tesla has introduced a new 40,000 SEK incentive in Sweden, lowering the price of its most affordable Model Y to a record low. The incentive effectively acts as a manufacturer-funded EV bonus and makes the entry-level Model Y more affordable.

As per a report from Swedish auto outlet Allt om Elbil, Tesla Sweden is offering a 40,000 SEK electric car bonus on the entry-level Tesla Model Y Rear-Wheel Drive variant. The incentive lowers the purchase price of the base all-electric crossover to 459,900–459,990 SEK, depending on listing.

The bonus applies to orders and deliveries completed by March 31, 2026. Tesla Sweden is also offering zero-interest financing as part of the campaign.

Last fall, Tesla launched a new base version of the Model Y starting at 499,990 SEK. The variant features a refreshed design and simplified equipment compared to the Premium and Performance variants. The new 40,000 SEK incentive now pushes the entry model well below the 460,000 SEK mark.

So far this year, the Model Y remains the most registered electric vehicle in Sweden and the third most registered new car overall. However, most registrations have been for higher Premium-spec versions. The new incentive could then be Tesla’s way to push sales of its most affordable Model Y variant in the country. 

Tesla is also promoting private leasing options for the entry-level Model Y at 4,995 SEK per month. Swedish automotive observers have noted that leasing may remain the more cost-effective option compared to purchasing outright, even after the new discount.

The base Model Y Rear-Wheel Drive offers a WLTP range of 534 kilometers, a top speed of 201 km/h, and a 0–100 km/h time of 7.2 seconds. Tesla lists energy consumption at 13.1 kWh per 100 kilometers, making it the most efficient version of the vehicle in the lineup and potentially lowering overall ownership costs.

Tesla is hiring an Autopilot Test Engineer in Shanghai, a move that signals continued groundwork for the validation of Full Self-Driving (FSD) in China. The role is based in Lingang, the district that houses Gigafactory Shanghai and has become a key testing zone for advanced autonomous features.

As observed by Tesla watchers, local authorities in Shanghai’s Nanhui New City within Lingang have previously authorized a fleet of Teslas to run advanced driving tests on public roads. This marked one of the first instances where foreign automakers were permitted to test autonomous driving systems under real traffic conditions in China. 

Tesla’s hiring efforts come amid ongoing groundwork for a full FSD rollout in China. Earlier reporting noted that Tesla China has been actively preparing the regulatory and infrastructure foundation needed for full FSD deployment, even though the company has not yet announced a firm launch date for the feature in the market.

As per recent comments from Tesla China Vice President Grace Tao, the electric vehicle maker has been busy setting up the necessary facilities to support FSD’s full rollout in the country. In a comment to local media, Tao stated that FSD should demonstrate a level of performance that could surpass human drivers once it is fully rolled out.

“We have set up a local training center in China specifically to handle this adaptation,” Tao said. “Once officially released, it will demonstrate a level of performance that is no less than, and may even surpass, that of local drivers.”

Tesla CEO Elon Musk has been quite bullish about a potential FSD rollout in China. During the 2025 Annual Shareholder Meeting, Musk emphasized that FSD had only received “partial approval” in China, though full authorization could potentially arrive around February or March 2026. This timeline was reiterated by the CEO during his appearance at the World Economic Forum in Davos.
