Tesla V4 Supercharger details: Charging Speed and Cable Length
Tesla opened its first V4 Superchargers in Europe today, kicking off the newest iteration of its charging network in Harderwijk, the Netherlands.
Details regarding charging speed, cable length, and others have not been officially detailed by Tesla, but Teslarati received some details from a visitor to the new V4 Supercharger today that will clarify some of the meat of what people want to know.

Charging Speed
Tesla’s V4 Superchargers still have the same output as the V3 Superchargers, which is rated at 250 kW. However, the changes in power are roughly 30 percent.
V3 Superchargers had an amperage of 425 A, while the new V4 Superchargers saw a 31 percent increase to 615 A, according to the panel label.

The label still shows the output power at 250 kW, but the rated current has gone from 425 to 615.
This may be to support new voltage architectures across multiple vehicle manufacturers. As most vehicles will shift to an 800-volt architecture, this will support faster charging speeds across many vehicles, not just Teslas.
Current 400-volt architectures will not support anything higher than roughly 250 kW, for now.
This may be why Tesla chose to roll out the V4 Superchargers in Europe, where the non-Tesla Supercharging Pilot Program has been in motion for a couple of years. In the United States, Tesla just enabled non-Tesla EVs to utilize the Supercharger Network.
Tesla V4 Charging Cable Length
Perhaps one of the biggest needs of the new Superchargers was a longer Supercharger cable, which could be utilized by many EV makers as charging ports are not always in the same locations.
In the past, the V4 Design hinted toward being more like a gas station to alleviate this problem, but it appears Tesla has ultimately chosen to lengthen the cable.

The V3 Superchargers offered a cable length of roughly 6 to 6.5 feet. Esther Kokkelmans, who visited the Supercharger in Harderwijk today and took pictures for Teslarati, said the new cable was roughly 2.9 to 3 meters in length. This is roughly 9.5 to 9.8 feet, which is significantly longer than the previous V3 Superchargers.

This is a sizeable increase that should alleviate most of the concerns regarding whether vehicles will be able to park correctly in the new spots. That is one issue many U.S. users have run into during early trials of non-Tesla EVs at Superchargers.

Tesla Model Y and Model 3 named safest vehicles tested by ANCAP in 2025
According to ANCAP in a press release, the Tesla Model Y achieved the highest overall weighted score of any vehicle assessed in 2025.
The Tesla Model Y recorded the highest overall safety score of any vehicle tested by ANCAP in 2025. The Tesla Model 3 also delivered strong results, reinforcing the automaker’s safety leadership in Australia and New Zealand.
According to ANCAP in a press release, the Tesla Model Y achieved the highest overall weighted score of any vehicle assessed in 2025. ANCAP’s 2025 tests evaluated vehicles across four key pillars: Adult Occupant Protection, Child Occupant Protection, Vulnerable Road User Protection, and Safety Assist technologies.
The Model Y posted consistently strong results in all four categories, distinguishing itself through a system-based safety approach that combines structural crash protection with advanced driver-assistance features such as autonomous emergency braking, lane support, and driver monitoring.

This marked the second time the Model Y has topped ANCAP’s annual safety rankings. The Model Y’s previous version was also ANCAP’s top performer in 2022.
The Tesla Model 3 also delivered a strong performance in ANCAP’s 2025 tests, contributing to Tesla’s broader safety presence across segments. Similar to the Model Y, the Model 3 also earned impressive scores across the ANCAP’s four pillars. This made the vehicle the top performer in the Medium Car category.
ANCAP Chief Executive Officer Carla Hoorweg stated that the results highlight a growing industry shift toward integrated safety design, with improvements in technologies such as autonomous emergency braking and lane support translating into meaningful real-world protection.
“ANCAP’s testing continues to reinforce a clear message: the safest vehicles are those designed with safety as a system, not a checklist. The top performers this year delivered consistent results across physical crash protection, crash avoidance and vulnerable road user safety, rather than relying on strength in a single area.
“We are also seeing increasing alignment between ANCAP’s test requirements and the safety technologies that genuinely matter on Australian and New Zealand roads. Improvements in autonomous emergency braking, lane support, and driver monitoring systems are translating into more robust protection,” Hoorweg said.

Tesla Sweden uses Megapack battery to bypass unions’ Supercharger blockade
Just before Christmas, Tesla went live with a new charging station in Arlandastad, outside Stockholm, by powering it with a Tesla Megapack battery.
Tesla Sweden has successfully launched a new Supercharger station despite an ongoing blockade by Swedish unions, using on-site Megapack batteries instead of traditional grid connections. The workaround has allowed the Supercharger to operate without direct access to Sweden’s electricity network, which has been effectively frozen by labor action.
Tesla has experienced notable challenges connecting its new charging stations to Sweden’s power grid due to industrial action led by Seko, a major Swedish trade union, which has blocked all new electrical connections for new Superchargers. On paper, this made the opening of new Supercharger sites almost impossible.
Despite the blockade, Tesla has continued to bring stations online. In Malmö and Södertälje, new Supercharger locations opened after grid operators E.ON and Telge Nät activated the sites. The operators later stated that the connections had been made in error.
More recently, however, Tesla adopted a different strategy altogether. Just before Christmas, Tesla went live with a new charging station in Arlandastad, outside Stockholm, by powering it with a Tesla Megapack battery, as noted in a Dagens Arbete (DA) report.
Because the Supercharger station does not rely on a permanent grid connection, Tesla was able to bypass the blocked application process, as noted by Swedish car journalist and YouTuber Peter Esse. He noted that the Arlandastad Supercharger is likely dependent on nearby companies to recharge the batteries, likely through private arrangements.
Eight new charging stalls have been launched in the Arlandastad site so far, which is a fraction of the originally planned 40 chargers for the location. Still, the fact that Tesla Sweden was able to work around the unions’ efforts once more is impressive, especially since Superchargers are used even by non-Tesla EVs.
Esse noted that Tesla’s Megapack workaround is not as easily replicated in other locations. Arlandastad is unique because neighboring operators already have access to grid power, making it possible for Tesla to source electricity indirectly. Still, Esse noted that the unions’ blockades have not affected sales as much.
“Many want Tesla to lose sales due to the union blockades. But you have to remember that sales are falling from 2024, when Tesla sold a record number of cars in Sweden. That year, the unions also had blockades against Tesla. So for Tesla as a charging operator, it is devastating. But for Tesla as a car company, it does not matter in terms of sales volumes. People charge their cars where there is an opportunity, usually at home,” Esse noted.
