Rivian’s color-coded battery charge indicator patent makes charging extra-convenient
Charging electric vehicle batteries is a task that is universal for all EV owners. Electric car makers across different brands have placed their own flourish to make their EV charging system unique, such as Tesla’s lighted indicators for the Model S, X, and Model 3. Electric truck maker Rivian aims to do the same thing, and if a recent patent application is any indication, it appears that the company is looking to make its battery charging indicators extra-convenient and creative at the same time.
There are times when electric car owners will find it difficult to determine the status of their vehicle while its batteries are charging. This is especially true during long trips, when vehicles are parked at public charging stations. If an owner is getting a bite or having a cup of coffee at a cafe, for example, it would be difficult to determine if the vehicle is done charging. Mobile apps showing the status of a vehicle are great, but it would be extra convenient if owners are able to see the status of a charging vehicle at a glance.
This is the central point of Rivian’s recent patent, titled “Exterior Light and Charge Indicator.” Engineers at Rivian believe EV owners should be able to determine the amount of battery charge that their vehicle has from a distance easily. Thus, the company has designed a system using bright LED bulbs that could be seen from across a parking lot or charging station. These LEDs will be integrated into the vehicle itself, as part of its lights.
“It would be advantageous to provide a user with an easy way to read a charge indicator of an electric vehicle. It would also be advantageous to provide a charge indicator that is visible a short or longer distance away from an electric vehicle. It would also be advantageous to utilize existing exterior lighting or lighting areas to provide a charge indicator,” the patent states.
The Rivian R1T pickup truck and R1S SUV are equipped with a long light strip in the middle that’s flanked by two rounded lights. This light strip, as per press images from the electric truck maker, will be used as a primary battery charge indicator if the vehicle is charging. Rivian’s recent patent explains the further use of this light strip in the section below.
“In some embodiments, the lighting control module is configured to cause the exterior light to emit light of a first color (e.g., white) during driving operation of the electric vehicle and emit light of a second color during charging, where the first color is different than the second color (e.g., blue). In some embodiments, the lighting control module is configured to cause the exterior light to emit light of a third color (e.g., green) when the vehicle battery is fully charged. In some embodiments, the lighting control module is configured to cause the exterior light to emit light of a fourth color (e.g., red) when there is a charging fault.”
Such a system would likely give Rivian owners a pretty easy way to determine if their truck or SUV is finished charging, or if there are any issues with the vehicle’s charging session. The fact that the light strip is fairly large works in Rivian’s favor, as there is no doubt that the LEDs would be very visible from a distance.
Another interesting aspect of this new idea is the use of a proximity sensor that could be configured to detect the presence of a person. This sensor would work much like a motion detection system and would light up in the event that a person is within 50 feet of the charging vehicle. It also could utilize a cell phone’s Bluetooth signal to determine when the owner is near. This would then activate the light system that would allow the driver to determine the progress of the charge.
Rivian has released a number of patents within the past few weeks. As the company is gearing up for production of its R1T pickup truck to begin at the tail end of 2020, the Plymouth, Michigan-based company is seemingly putting the final touches on its vehicles before the first units are delivered to reservation holders. Following the R1T, Rivian is also expected to start the production of its seven-seater SUV, the R1S.

Tesla is updating Cybertruck owners on its timeline of a massive feature that has yet to ship: Powershare with Powerwall.
Powershare is a bidirectional charging feature exclusive to Cybertruck, which allows the vehicle’s battery to act as a portable power source for homes, appliances, tools, other EVs, and more. It was announced in late 2023 as part of Tesla’s push into vehicle-to-everything energy sharing, and acting as a giant portable charger is the main advantage, as it can provide backup power during outages.
Cybertruck’s Powershare system supports both vehicle-to-load (V2L) and vehicle-to-home (V2H), making it flexible and well-rounded for a variety of applications.
However, even though the feature was promised with Cybertruck, it has yet to be shipped to vehicles. Tesla communicated with owners through email recently regarding Powershare with Powerwall, which essentially has the pickup act as an extended battery.
Powerwall discharge would be prioritized before tapping into the truck’s larger pack.
However, Tesla is still working on getting the feature out to owners, an email said:
“We’re writing to let you know that the Powershare with Powerwall feature is still in development and is now scheduled for release in mid-2026.
This new release date gives us additional time to design and test this feature, ensuring its ability to communicate and optimize energy sharing between your vehicle and many configurations and generations of Powerwall. We are also using this time to develop additional Powershare features that will help us continue to accelerate the world’s transition to sustainable energy.”
Owners have expressed some real disappointment in Tesla’s continuous delays in releasing the feature, as it was expected to be released by late 2024, but now has been pushed back several times to mid-2026, according to the email.
Foundation Series Cybertruck buyers paid extra, expecting the feature to be rolled out with their vehicle upon pickup.
Cybertruck’s Lead Engineer, Wes Morrill, even commented on the holdup:
As a Cybertruck owner who also has Powerwall, I empathize with the disappointed comments.
To their credit, the team has delivered powershare functionality to Cybertruck customers who otherwise have no backup with development of the powershare gateway. As well as those with solar…

He said that “it turned out to be much harder than anticipated to make powershare work seamlessly with existing Powerwalls through existing wall connectors. Two grid-forming devices need to negotiate who will form and who will follow, depending on the state of charge of each, and they need to do this without a network and through multiple generations of hardware, and test and validate this process through rigorous certifications to ensure grid safety.”
It’s nice to see the transparency, but it is justified for some Cybertruck owners to feel like they’ve been bait-and-switched.
Tesla has opened its northernmost Supercharger in Fairbanks, Alaska, with eight V4 stalls located in one of the most frigid cities in the U.S.
Located just 196 miles from the Arctic Circle, Fairbanks’s average temperature for the week was around -12 degrees Fahrenheit. However, there are plenty of Tesla owners in Alaska who have been waiting for more charging options out in public.
There are only 36 total Supercharger stalls in Alaska, despite being the largest state in the U.S.
Eight Superchargers were added to Fairbanks, which will eventually be a 48-stall station. Tesla announced its activation today:

The base price per kWh is $0.43 at the Fairbanks Supercharger. Thanks to its V4 capabilities, it can charge at speeds up to 325 kW.
Despite being the northernmost Supercharger in North America, it is not even in the Top 5 northernmost Superchargers globally, because Alaska is south of Norway. The northernmost Supercharger is in Honningsvåg, Norway. All of the Top 5 are in the Scandanavian country.
Tesla’s Supercharger expansion in 2025 has been impressive, and although it experienced some early-quarter slowdowns due to V3-to-V4 hardware transitions, it has been the company’s strongest year for deployments.
🚨🚨 Tesla Supercharging had a HUGE year, and they deserve to be recognized.

Through the three quarters of 2025, the company has added 7,753 stations and 73,817 stalls across the world, a 16 percent increase in stations and an 18 percent increase in stalls compared to last year.
Tesla is on track to add over 12,000 stalls for the full year, achieving an average of one new stall every hour, an impressive statistic.
Recently, the company wrapped up construction at its Supercharger Oasis in Lost Hills, California, a 168-stall Supercharger that Tesla Solar Panels completely power. It is the largest Supercharger in the world.

Tesla shocks with latest Robotaxi testing move
Why Tesla has chosen to use a couple of Model S units must have a reason; the company is calculated in its engineering and data collection efforts, so this is definitely more than “we just felt like giving our drivers a change of scenery.”
Tesla Model S vehicles were spotted performing validation testing with LiDAR rigs in California today, a pretty big switch-up compared to what we are used to seeing on the roads.
Tesla utilizes the Model Y crossover for its Robotaxi fleet. It is adequately sized, the most popular vehicle in its lineup, and is suitable for a wide variety of applications. It provides enough luxury for a single rider, but enough room for several passengers, if needed.
However, the testing has seemingly expanded to one of Tesla’s premium flagship offerings, as the Model S was spotted with the validation equipment that is seen entirely with Model Y vehicles. We have written several articles on Robotaxi testing mules being spotted across the United States, but this is a first:
🚨 Tesla is using Model S vehicles fitted with LiDAR rigs to validate FSD and Robotaxi, differing from the Model Ys that it uses typically
Those Model Y vehicles have been on the East Coast for some time. These Model S cars were spotted in California https://t.co/CN9Bw5Wma8 pic.twitter.com/UE55hx5mdd

Why Tesla has chosen to use a couple of Model S units must have a reason; the company is calculated in its engineering and data collection efforts, so this is definitely more than “we just felt like giving our drivers a change of scenery.”
It seems to hint that Tesla could add a premium, more luxury offering to its Robotaxi platform eventually. Think about it: Uber has Uber Black, Lyft has Lyft Black. These vehicles and services are associated with a more premium cost as they combine luxury models with more catered transportation options.
Tesla could be testing the waters here, and it could be thinking of adding the Model S to its fleet of ride-hailing vehicles.
Reluctant to remove the Model S from its production plans completely despite its low volume contributions to the overall mission of transitioning the world to sustainable energy, the flagship sedan has always meant something. CEO Elon Musk referred to it, along with its sibling Model X, as continuing on production lines due to “sentimental reasons.”
However, its purpose might have been expanded to justify keeping it around, and why not? It is a cozy, premium offering, and it would be great for those who want a little more luxury and are willing to pay a few extra dollars.
Of course, none of this is even close to confirmed. However, it is reasonable to speculate that the Model S could be a potential addition to the Robotaxi fleet. It’s capable of all the same things the Model Y is, but with more luxuriousness, and it could be the perfect addition to the futuristic fleet.
