Why are Tesla Superchargers Only for Long-distance Travel?

Before going on vacation around July 4th holiday, PlugInsights sent a short survey to me with questions about Tesla supercharging procedures and also about recent comments by Elon Musk. About half way into the short survey, it delves into Elon Musk’s supercharging “overuse” comment regarding some daily Tesla commuters relying on the free charging stations in southern California.

My first thought, this again. Musk’s comments made some waves last month but why dredge this issue to the surface in the form of a survey from PlugInsights, a division of RECARGO.

Is something afoot at Tesla? Why is the company worried enough to conduct a survey about this topic and especially Musk’s comments at the annual shareholders meeting. One question from the survey actually discusses the actual comments by Musk. “Before today, were you aware that Mr. Musk recently made these statements?”

Below are Musk’s comments at the recent annual shareholders meeting held in June:

(paraphrased via the survey)…”that superchargers are meant for free, long-distance travel” and “that drivers who aggressively use the network for local charging may receive an email reminder that it’s ‘cool to do this occasionally but it’s meant for a long-distance thing.’

So why did Elon Musk comment on this relatively small issue? Ashley Vance recent biography on Elon Musk points out that Musk usually doesn’t get involved in PR, unless an issue threatens one of his companies. So how could this threaten Tesla Motors? My speculation is the very real possibility of  battery capacity loss and drastically reduced range with multiple instances of DC fast-charging on a daily basis.

Could these patterns lead to drastically reduced battery packs ranges by year three or four of ownership and possibly lead to Tesla replacing a lot of battery packs, due to their warranty coverage?

My speculation centers around 120 kW of DC energy flowing into the battery pack on a daily basis. Did Tesla test battery packs for multiple, daily DC-charging usage? Maybe not.

Musk mentioned at the annual shareholder meeting that fast charging was intended for destination traveling and implied it wasn’t for daily use by commuters.

The Idaho National laboratory conducted a study on DC fast-charging and its effects on battery packs some years ago and released findings in 2014. Using 2012 Nissan Leafs, the study compared the effects of different types of charging: level 2 charging (3.3 kW) and DC fast-charging (50 kW).

The study revealed after 40,000 miles of testing that there was little loss of initial capacity and that the DC-fast charging battery pack had only lost 3 percent more than the other Nissan Leaf using level 2 battery charging.

Survey on usage of Tesla Superchargers

However, Tesla Superchargers are dishing out 120 kW DC versus the Idaho study of 50 kW, more than 2x the amount of electricity coming into battery pack. That’s a lot stress on the battery management system to keep heat levels down, plus these car owners are supercharging daily, maybe doing it twice a day?

Many automakers have said that DC fast charging is fine on the battery pack, as long as it’s not done excessively. It seems twice a day could be considered excessive and cause concern for Tesla execs. This could be leading up to some proviso with excessive supercharging and the battery pack warranty, hence the PlugInsights survey on usage and expectations.

What about you, any other thoughts on why this is such an issue for Tesla?

** My other mild theory is Tesla’s rising electricity costs for owners employing supercharging only mode. The results of PlughInsights survey showed that 26% of Model S owners polled have used Tesla Superchargers as a free local alternative to home charging.

Tesla’s reason for Starlink integration on Cybercab might surprise you

Tesla’s reason for Starlink integration on Cybercab might surprise you, as the company’s Head of AI, Ashok Elluswamy, finally shed some light on the reason they are putting a satellite internet terminal on its ride-hailing-geared vehicle.

On Monday, Tesla officially confirmed that it would integrate Starlink V5 terminals into Cybercab vehicles, something many Tesla fans had figured the company would do, as the vehicle is primarily geared toward giving rides without any passenger intervention.

The ability to access the internet would allow riders to work or play in the car with their devices. It seemed like a more-than-reasonable feature to add to the Cybercab, which made its way off the production lines for the first time earlier this year.

However, the move is not for the rider, as Elluswamy confirmed on Monday night. Instead, it’s actually for Tesla to be able to have a constant connection to the cars in the Robotaxi fleet so it can troubleshoot issues, contact riders, or resolve other issues.

Elluswamy said:

“It is still not required for safe operation of the vehicle. Connectivity is primarily meant for navigation, customer service and, in general, fleet management.”

Many initially assumed the option of constant connectivity would be enabled on the Cybercab for passenger entertainment or work. With the Cybercab, passengers won’t be doing anything but enjoying the ride, so it seemed more than logical that they would be hanging out with Starlink internet access as an amenity.

However, Tesla’s primary concern with Robotaxi is safety, and nailing these first unsupervised rides is a crucial step to setting a good narrative on how effective driverless transportation can be.

Being able to get in touch with passengers or a vehicle if something is wrong is a crucial part of the overall experience, and preventative measures are being taken by Tesla to ensure a smooth process, even in the worst-case.

Tesla Robotaxi program expands in Florida to two new cities

Published

Tesla has expanded its Robotaxi program in Florida to include two new cities: Tampa and Orlando.

This marks the second and third cities to be added to the company’s available locations for autonomous ride-hailing in the Sunshine State, joining Miami, which was the first Florida city to offer Robotaxi rides.

Tesla announced the addition of Orlando and Tampa to the Robotaxi program on Tuesday morning. The cities now join Austin, Dallas, Houston, Miami, and the San Francisco Bay Area as locations where Tesla can operate its Robotaxi platform:

These rides are unsupervised, as AI Head Ashok Elluswamy confirmed the suite in Florida is operating without safety drivers or anyone within the cabin to assist with operation.

Orlando Tesla Robotaxi Operation

The geofence in Orlando covers a prominent irregular shaded zone on the map, roughly 4-6 miles across in key dimensions, so it likely measures somewhere between 25 and 45 square miles, which is comparable to other early Tesla launches in other cities.

It encompasses central and southern areas bounded by major highways including SR-417 and SR-528, including parts of the Orlando metro core, tourism-adjacent zones, and residential/commercial districts. This represents an initial targeted rollout in a tourist-heavy region, positioned for quick expansion via Tesla’s software updates.

Tampa Tesla Robotaxi Operation

In Tampa, the shape of the geofence is a shaded polygon covering key neighborhoods, explicitly including West Tampa, Tampa Heights, Hyde Park, and downtown Tampa proper, with boundaries along major roads and the Hillsborough River area.

This focuses on high-demand central zones and will offer tourists and citygoers rides without drivers.

Robotaxi Progress

Tesla has been operating Robotaxi since last June, when it launched in Austin. The geofences in most regions have already expanded several times since their launch last year, but the bigger complaint is vehicle availability. Tesla has been working to add more Robotaxi-enabled vehicles to its fleet.

The company still plans to utilize its Cybercab, a new vehicle that is being produced at Gigafactory Texas, for the Robotaxi suite alongside the Model Y, which has been the vehicle of choice for Tesla with early operations.
