Tesla posted 14,300 insurance registrations in China during the week of September 1–7, a 14.4% increase from the previous week’s 12,500 units. 

The figure marks Tesla’s highest weekly performance so far this quarter so far, despite the company’s year-over-year figures still being below 2024’s numbers.

Weekly registrations

The week’s registrations broke down to 5,000 Model 3s and 8,400 Model Ys, including the first 900 units of the newly launched Model Y L variant, as per estimates from industry watchers. On a quarterly basis, Tesla China is tracking 41.3% growth compared to the previous quarter, which bodes well for the company’s results this Q3 2025.

For the month of August, Tesla sold 57,152 vehicles in China, down 9.93% from the same period in 2024 but up 40.7% from July’s 40,617 units, according to the China Passenger Car Association (CPCA). Year-to-date, Tesla’s China sales are 7.2% lower compared to the previous year.

Model Y L first deliveries

The week ending September 7 was the first week that included the newly released Model Y L, a six-seat extended wheelbase version of the company’s best-selling all-electric crossover. Industry watchers estimate that last week, the first 900 units of the Model Y L have been registered, though this number is expected to increase in the coming weeks as deliveries of the vehicle hit their pace.

Citing information from a Tesla store in Beijing, Chinese media outlet Cailianshe stated that the Model Y L has been seeing a lot of interest among car buyers. “(The Model Y L) is selling very well. Since its launch, 120,000 orders have been received, with nearly 10,000 orders placed every day. The first batch of customers began receiving deliveries in the past two days,” a Tesla representative stated.

Tesla has introduced MultiPass, a new feature that allows owners to use their Tesla account to charge at non-Tesla charging stations. 

The service launched this week in the Netherlands, giving drivers the ability to find chargers, start sessions, and view charging history directly within the Tesla app.

Streamlining third-party charging

With MultiPass, Tesla owners can activate charging either through the Tesla app or by using their existing Tesla key card. This eliminates the need for separate accounts or additional cards from third-party networks. Tesla Charging highlighted the convenience of managing charging sessions in one location in a post on X, while Max de Zegher, Tesla’s Director of Charging for North America, emphasized that the update removes unnecessary friction.

“Nobody likes creating more accounts with payment details and passwords. For charging, this can even mean needing a third-party charging card mailed to your house. Starting in the Netherlands today, your Tesla App and your existing (!) Tesla keycard can start charging at third-party chargers. We’ll expand this to more countries quickly if customers love it. To make ownership effortless, the Tesla App should really be the only thing you need,” the Tesla executive wrote in a post on X.

Third-party payments and a familiar name

Tesla owners could pay for their third-party charging session with their Tesla accounts, as per the electric vehicle maker on its official website. Payments are drafted from users’ default payment method in the Tesla App, though charging costs will still vary depending on the third-party charger that is used.

Interestingly, the MultiPass name also echoes a pop culture reference. In the 1997 sci-fi film The Fifth Element, Leeloo Dallas-505 carried a futuristic “Multipass” smart card that functioned as her ID, passport, and ticket to space travel. Her accented repetition of “Multipass!” became one of the film’s most memorable lines, and it highlighted the card’s all-in-one convenience.

Tesla has not provided a timeline for Multipass’ U.S. rollout, though the service could become an important addition to the growing but often fragmented landscape of DC fast charging.

Tesla has unveiled the Megablock and Megapack 3, the latest additions to its industrial-scale battery storage solution lineup. 

The products highlight Tesla Energy’s growing role in the company, as well as the division’s growing efforts to provide sustainable energy solutions for industrial-scale applications.

Megablock targets speed and scale

During the “Las Megas” event in Las Vegas, Tesla launched Megablock, a pre-engineered medium-voltage block designed to integrate Megapack 3 units in a plug-and-play system. Capable of 20 MWh AC with a 25-year life cycle and more than 10,000 cycles, the Megablock could achieve 91% round-trip efficiency at medium voltage, inclusive of auxiliary loads.

Tesla emphasized that Megablock can be installed 23% faster with up to 40% lower construction costs. The platform eliminates above-ground cabling through a new flexible busbar assembly and delivers site-level density of 248 MWh per acre. With Megablock, Tesla is also aiming to commission 1 GWh in just 20 business days, or enough to power 400,000 homes in less than a month. 

“With Megablock, we are targeting to commission 1 GWh in 20 business days, which is the equivalent of bringing power to 400,000 homes in less than a month. It’s crazy. How are we planning to do that? Like most things at Tesla, we are ruthlessly attacking every opportunity to save our customers time, simplify the process, remove steps, (and) automate as much as we can,” the company said. 

Megapack 3 is all about simplicity

The Megapack 3 is Tesla’s next-generation utility battery, designed with a simplified architecture that cuts 78% of connections compared to the previous version. Its thermal bay is drastically simplified, and it uses a Model Y heat pump on steroids. The battery weighs about 86,000 pounds and holds 5 MWh of usable AC energy. Tesla engineers incorporated a larger battery module and a new 2.8-liter LFP cell co-developed with the company’s cell team.

The Megapack 3 is designed for serviceability, and it features easier front access and no roof penetrations. About 75% of Megapack 3’s total mass is battery cells, with individual modules weighing as much as a Cybertruck. It’s also tough, with an ambient operating temperature range from -40C to 60C. This should allow the Megapack 3 to operate optimally from the coldest to the hottest regions on the planet.

Production is set to begin at Tesla’s Houston Megafactory in late 2026, with planned capacity of 50 GWh per year. Additional supply will come from Tesla’s 7 GWh LFP facility in Nevada, which is expected to open in 2025, as well as with third-party partners.
