How to Re-calibrate Your Tesla Window Regulator

Oct 16, 2024

Tesla showed previews of its upcoming wireless charging system at We, Robot. The slides were out of view on the live stream (at the 16:35 mark), but attendees managed to capture what was on screen.

We previously looked at Tesla's patent on Wireless Charging, as well as the fact that FSD will support automatic docking for the Wireless Charger, but this time, let’s look at what Tesla actually has to show.

On the slides, Tesla showed off the actual wireless charger - which seems to be a large square with a cable coming out of the back. Overall, it looks like a simplistically designed and functional object, is easy to keep clean, and ensures it's in the right spot for alignment purposes.

But on the next slide, Tesla showed off some interesting information. For context, the Level II Wall Connector that Tesla currently sells runs at 48 amps, at 240 volts. That puts out 11.5kW of power for the car to charge off of - with an approximately 99.33% efficiency, depending on the distance between your wall connector and service box.

The wireless charger is likely running at an even higher amperage - we estimate approximately 80+ amps at 240 volts - to put out a jaw-dropping 20+kW to the vehicle. 100 amps is usually the next service level after the 60 amp service level, and with a 20% amperage loss for electrical codes, an 80 amp charger may be in line.

Tesla has said before that its wireless charging system would be very efficient, but it's not clear yet how efficient it will be. However, knowing that remembering to charge is one of the mainstream obstacles in EV adoption, an automated, wireless charging solution would likely help EV adoption and give Tesla an advantage over the competition.

Tesla may have cracked the nut on wireless vehicle charging here - and the Cybertruck is the first of their consumer vehicles that has the ability to get a retrofit for wireless charging. We’re excited to see what Tesla has up their sleeves on this front.
