Tesla Shares Details of Its Upcoming Wireless Charger [VIDEO]

Not a Tesla App

Tesla has confirmed that its upcoming wireless charging intended for the Robotaxi is “well above 90%” efficient. While wireless charging for smartphones tends to be about 70-75% efficient in general, a lot of the inefficiency comes from heat and alignment issues.

Tesla appears to have tackled both of these key problems to make wireless charging efficient enough for electric vehicles. Let’s take a look at how, but before we do that, let’s take a look at SAE J2954, the wireless EV charging standard from nearly half a decade ago.

SAE J2954

SAE’s wireless charging standard was created in October 2020. Engineers from SAE and car manufacturers collaborated to build a standard that would work across all EVs. In the end, they figured out a grid-to-battery efficiency of up to 94%. The NACS connector itself is only slightly more efficient—98.55% or so, depending on the temperature of the connector, the cable, the battery pack, and the transformer. That sets a benchmark for what Tesla aims to meet with its wireless charging standard.

What were their key challenges for efficiency? Heat and alignment.

Autopark for Wireless Chargers

Tesla’s Autopark will receive special support for its wireless chargers. Autopark will automatically locate the wireless charging pad and park the vehicle in the best spot for the charging session to begin. As long as the vehicle can accurately place itself over the wireless charger, this solves one of the key issues with wireless charging. It’s not clear whether Tesla is building in any other technology to help the charger find its optimal position. In theory, magnets, like the newer Qi2 standard or Apple’s MagSafe, can help the charger lock in millimeter-perfect positioning.

Having the vehicle locate and park itself over the charger will be far easier than humans trying to accomplish the same feat without software assistance.

Heat Management

A major problem with cell phones and wireless charging is that most do not have active heat dissipation. Instead, they dissipate heat passively into the atmosphere around them. This is especially true due to the small surface area of a cell phone.

In a car, you can transfer heat efficiently to outside the vehicle or into the vehicle’s cabin if it needs heat - the heat pumps on a Tesla are 200-300% efficient at most temperatures. Conversely, on cell phones, battery heat must be limited due to the critical and heat-sensitive components (screen, chips, cameras, sensors) that are all tightly packed into the phone’s battery.

Due to Tesla’s BMS (battery management system), Tesla can keep the vehicle’s batteries and surrounding components in a much more ideal range than cell phones. The system will not only cool down batteries, but also warm them up to produce efficiency and faster charging.

Beam Steering

The final trick under the charge mat is beam steering. In a recent patent, Tesla explained that they intend to steer the beam of wireless energy by altering the induced current across the wireless charging pad’s coils. This will allow them to solve both the alignment and heat issues.

The alignment's precision can be achieved by steering the beam into the optimal position, while it dynamically adjusts between 'cool zones' on the receiving vehicle to prevent overheating—ensuring a steady and efficient rate of charging.

Tesla has thought out the wireless charging problem pretty deeply ever since they bought out Wiferion, and this achievement has been years in the making. We’re hoping they’ll eventually bring wireless charging compatibility to the rest of the lineup. The Cybertruck itself already has the connector prongs to be retrofitted with a wireless charging adapter, and with the Model Y Juniper Refresh around the corner, what better way to prove wireless EV charging works than to include it in the world’s best-selling car?

Tesla Expected to Offer FSD Transfers in Europe

Not a Tesla App

It has been a long wait for FSD for European customers, many of whom paid for the feature years ago on now legacy hardware. While the FSD transfer program has come and gone multiple times, there’s something to be said about having it available in North America, where it can be used, and in Europe or other countries, where it still just remains the same as Enhanced Autopilot (differences between Autopilot, EAP, and FSD).

FSD Transfer is a nice goodwill gesture from Tesla that in theory doesn’t cost them anything. Instead, it keeps customers, especially those who have been waiting for years, loyal and happy. It also incentivizes them to upgrade to a newer Tesla with HW4, where FSD will hopefully be achieved.

In a reply to a post on X, Elon agreed with the suggestion that offering FSD transfers in Europe would be a fair solution for those who have already purchased FSD but can’t use its capabilities.

Sounds fair

— Elon Musk (@elonmusk) July 13, 2025

A Fair Solution

FSD Transfer directly addresses a growing concern for many long-term European Tesla owners. Thousands of customers purchased the full package, often many years ago, with the expectation that FSD would eventually be capable and approved for use. However, the reality is that FSD, even as an advanced driver assistance system (ADAS), continues to be pushed back in Europe.

As the regulatory process continues at a snail's pace, many of these early supporters are now reaching or have already passed the point where they’re ready to upgrade to a new Tesla.

Without the transfer program, it's a difficult choice: either throw away your original investment in FSD and pay for the package a second time (FSD price history), or subscribe to it in the future.

Offering FSD transfers is a good way for Tesla to meet them halfway. It's a difficult situation, and one that’s being hindered by processes beyond the control of both the customer and Tesla. However, a transfer helps both parties. Tesla sells another vehicle, and the customer gets to keep FSD.

When Will it Be Available?

Based on how FSD transfers have worked in the past following Elon’s announcements, this feature is likely to become available for a limited time period in the coming days or weeks. If it happens, we should expect an announcement from Tesla Europe on X and emails being sent out to Tesla customers.

Once the program is in place, all you need to do is complete your vehicle purchase and then inform your Tesla sales advisor that you’d like to transfer FSD. You don’t even have to sell or trade in your old Tesla; FSD will simply be removed from it as a feature.

Hopefully, Tesla enables FSD Transfers for everyone, regardless of region. It should be an ongoing offer until at least FSD is approved in the given country or region.

Tesla Increases Robotaxi Fare Fee, Up from $4.20

Not a Tesla App

The introductory price for Tesla’s Robotaxi Network has finally been updated. In a post on X, Elon Musk confirmed that the new fare would be rolling out to complement the new Robotaxi geofence expansion.

This change marks the first adjustment to Tesla’s fares since the initial $4.20 launch price 23 days ago. While the price increase may seem significant in terms of percentages, when compared to other options in the ride-hailing area, it is still drastically cheaper.

But the price is now a princely $6.90, as foretold in the prophecy 😂

— Elon Musk (@elonmusk) July 14, 2025

Context Matters

Robotaxi currently operates on a simple, flat-rate model. The new $6.90 fare gets you a ride to anywhere within the recently expanded geofence.

So far, this is the opposite approach compared to other services, such as Waymo or traditional ride-sharing options like Uber and Lyft. All these services use dynamic pricing based on distance, time of day, and demand. A comparable trip on any one of these services could cost anywhere from $30 to $65, and potentially even higher during peak hours.

That doesn’t even include the tip fees for human drivers either - another win for Robotaxi (can you tip a Robotaxi?).

Even with the adjustment, the flat $6.90 fare remains less than half the price of a typical competing ride, making Robotaxi the most affordable point-to-point transportation option in Austin, aside from mass transit, for now.

A “Maturing” Service

The price change, moving from one meme-worthy number to another, is a sign that Robotaxi is finally graduating from its initial pilot phase. Following the first major expansion of the service area, this adjustment is a logical next step towards finding a more sustainable flat price.

While the new fare is a 65% increase over the old fare, the key takeaway is that it is still far cheaper than other options, and still just as meme-worthy. Tesla is aiming to have its early access riders complete as many rides as possible during these early months, and this pricing is still very reflective of that.
