Tesla Megapack fire in Australia did not start from battery modules: analysis

While undergoing its commissioning process in late September, a fire broke out in one of the Tesla Megapacks at the Bouldercombe big battery in Queensland, Australia. The fire triggered debates about the viability of renewable energy solutions, as well as the safety of battery storage systems. 

The fire was not severe, with Genex Power, the owner of the battery storage system, stating that the fire did not even necessitate the use of water at all. Genex CEO Craig Francis also noted that the isolated nature of the fire suggests that the incident would not have any significant impact on the Bouldercombe big battery. 

And as per an announcement from Genex Power, the fire actually did not start at the Megapack’s battery modules. Instead, the fault initially occurred on the AC side of the impacted Megapack unit. The fault then propagated to the battery modules within the Megapack. This was determined following an analysis of the incident by Tesla, Genex, and other stakeholders.

Genex described the findings of the Megapack battery fire analysis in its announcement

“The preliminary RCA indicates that a fault occurred on the AC side of the Megapack unit. The fault then propagated to the battery modules within the Megapack. The burn of the Megapack followed design and certification testing expectations under UL9540A, with no external water required, and no propagation of the active fire to adjacent Megapack units or balance of plant.

“The failure has been isolated to the power electronics interface with the AC bus bar in the individual Megapack unit itself and not the broader installation of Megapack units. In order to mitigate against a further event, Tesla will be undertaking replacement of two identified power electronics units and out of caution, physical inspection of the power electronics within the remainder of units at the Project site. Genex will also be implementing upgrades to breaker control setting response times to further mitigate against a potential future event,” Genex wrote.

While the minor fire affected one Megapack battery in the Bouldercombe site, the Megapack adjacent to the impacted unit also suffered minor thermal damage to its electrical insulation. Thus, Tesla would be providing two Megapacks to replace the two units that were damaged by the fire. The Megapacks are already en route to the site, and are expected to arrive in early December 2023, as noted in a PV Magazine Australia report.

Elon Musk argues lidar and radar make self driving cars more dangerous

The CEO is not just stating that using sensors like lidar is unnecessary to achieve self-driving.

Elon Musk is taking a firmer stance in the vision vs lidar debate for autonomous driving. In his more recent comments, the CEO is not just stating that using sensors like lidar is unnecessary to achieve self-driving. 

Musk is stating that using lidar actually makes self-driving cars more dangerous. 

Uber CEO’s comments

During a recent interview, Uber CEO Dara Khosrowshahi shared his thoughts on the autonomy race. As per the CEO, he is still inclined to believe that Waymo’s approach, which requires outfitting cars with equipment such as lidar and radar, is necessary to achieve superhuman levels of safety for self-driving cars. 

“Solid state LiDAR is $500. Why not include lidar as well in order to achieve super human safety. All of our partners are using a combination of camera, radar and LiDAR, and I personally think that’s the right solution, but I could be proven wrong,” the Uber CEO noted.

Elon Musk’s rebuttal

In response to the Uber CEO’s comments, Elon Musk stated that lidar and radar, at least based on Tesla’s experience, actually reduce safety instead of improving it. As per the Tesla CEO, there are times when sensors such as lidar and radar disagree with cameras. This creates sensor ambiguity, which, in turn, creates more risk. Musk then noted that Tesla has seen an improvement in safety once the company focused on a vision only approach.

“Lidar and radar reduce safety due to sensor contention. If lidars/radars disagree with cameras, which one wins? This sensor ambiguity causes increased, not decreased, risk. That’s why Waymos can’t drive on highways. We turned off the radars in Teslas to increase safety. Cameras ftw,’ Musk wrote.

Musk’s comments are quite notable as Tesla was able to launch a dedicated Robotaxi pilot in Austin and the Bay Area using its vision-based autonomous systems. The same is true for FSD, which is quickly becoming notably better than humans in driving.

Tesla Model Y L sold out for September 2025

This was hinted at in Tesla China’s configurator for the all-electric crossover.

It appears that the Tesla Model Y L has been sold out in China for September 2025. This was hinted at in Tesla China’s configurator for the all-electric crossover.

Model Y L deliveries

Since the Model Y L’s official launch earlier this month, Tesla has been pretty consistent in the idea that the extended wheelbase variant of its best-selling vehicle will see its first deliveries sometime in September. This was quite an impressive timeframe for Tesla, considering that the Model Y L has only been launched this August. 

Nevertheless, both Tesla China’s Model Y configurator and comments from company executives have noted that the vehicle will see its first customer deliveries in September. “Tesla cars are fun to drive alone, whether you have children or how many children, this car can meet all your needs. We will deliver in September and wait for you to get in the car,” Tesla China VP Grace Tao wrote on Weibo.

October 2025 deliveries

A look at Tesla China’s order page as of writing shows that the earliest deliveries for the Model Y L, if ordered today, would be October 2025 instead. This suggests that the six-seat Model Y variant has effectively been sold out for September. This bodes well for the vehicle, and it suggests that it is a variant that may be able to raise Tesla’s sales numbers in China, as well as territories where the Model Y L could be exported.

Rumors of the Model Y L’s strong sales have been abounding. After the vehicle’s launch, industry watchers estimated that Tesla China has received over 35,000 orders for the Model Y L in just one day. Later estimates suggested that the Model Y L’s orders have breached the 50,000 mark.

Starship Flight 10 rescheduled as SpaceX targets Monday launch

SpaceX said it is now targeting Monday evening for Starship’s 10th flight test.

SpaceX stood down from its planned Starship Flight 10 on Sunday evening, citing an issue with ground systems. 

The launch attempt was scheduled during a one-hour window that opened at 7:30 p.m. ET, but it was called off just 17 minutes before the window opened. SpaceX said it is now targeting Monday evening for Starship’s 10th flight test.

Flight 10 rescheduled

A lot of excitement was palpable during the lead up to Starship Flight 10’s first launch window. After the failures of Starship Flight 9, many were interested to see if SpaceX would be able to nail its mission objectives this time around. Starship itself seemed ready to fly, with the upper stage being loaded with propellant as scheduled. Later on, SpaceX also noted that Starship’s Super Heavy booster was also being loaded with propellant.

However, 17 before the launch window opened, SpaceX noted that it was “standing down from today’s tenth flight of Starship to allow time to troubleshoot an issue with ground systems.” Elon Musk, in a post on X, further clarified that a “ground side liquid oxygen leak needs to be fixed.” Musk did state that SpaceX will attempt Flight 10 again on Monday, August 25, 2025.

Starship and SpaceX’s development goals

The fully integrated Starship system is the tallest and most powerful rocket ever built, standing over 400 feet when stacked. Composed of the reusable Super Heavy booster and the Starship upper stage, the vehicle is central to SpaceX’s long-term ambitions of lunar and Martian missions. NASA has already selected Starship as the crewed lunar lander for Artemis, with its first astronaut landing mission tentatively set for 2027, as noted in a Space.com report.

So far, Starship has flown nine times from Starbase in Texas, with three launches this year alone. Each flight has offered critical data, though all three 2025 missions encountered notable failures. Flight 7 and Flight 8 ended in explosions less than 10 minutes after launch, while Flight 9 broke apart during reentry. Despite setbacks, SpaceX has continued refining Starship’s hardware and operations with each attempt. Needless to say, a successful Flight 10 would be a significant win for the Starship program.
