Rivian set to debut energy storage project using ‘second life’ batteries from vehicles
Rivian Automotive and the Honnold Foundation are working together in an initiative that is set to use the electric truck maker’s “second-life” batteries as stationary energy storage units in a microgrid project at Adjuntas, Puerto Rico. This marks a huge step for Rivian, which is planning on expanding its reach beyond the manufacture of all-electric luxury adventure vehicles.
Rivian will be utilizing 135 kWh battery packs from its development vehicles for the upcoming energy storage project, which is expected to launch in 2020. The company has designed its battery packs and modules in such a way that they can be easily transitioned from vehicle energy storage to stationary energy storage at the end of their vehicle life. The Rivian CEO described the concept in a press release.
“Second-life batteries are a big enabler to accelerating widespread adoption of renewable energy, and it’s exciting to envision this system contributing importantly to a community. This project allows us to model a customized energy storage solution that takes into account space constraints, disaster resiliency, and energy independence,” Scaringe said.
Using older batteries for energy storage is a clever way for Rivian to recycle the cells it uses for its all-electric trucks. While batteries at the end of their vehicle life will likely show some wear compared to those used in new EVs, they could still function well as stationary energy storage units. After all, optimal batteries for electric trucks require a lot of power, but those energy storage units could make do with much less (propelling the R1T from 0-60 mph, for example, takes a lot of power, but turning on the lights in a household does not require as much).
Rivian and the Honnold Foundation selected Adjuntas, Puerto Rico as the site of their microgrid project partly due to the town being in need of help. Adjuntas was struck by Hurricane Maria in 2017, and the community has been struggling with power since. If successful, Rivian and Honnold’s microgrid initiative could help many of the businesses located near the town’s main square. Residents could also have backup power in the event that power shortages happen.
Further details of the project will be discussed by RJ Scaringe and elite climber Alex Honnold at Denver, CO on June 15 in a livestreamed event, which could be accessed here.

DENVER, June 13, 2019 /PRNewswire/ — On June 15, electric adventure vehicle maker Rivian is announcing a project to use its second-life batteries in a solar microgrid initiative with the Honnold Foundation. The goal: to support energy independence and adoption of renewable power generation. The project, in the town of Adjuntas, Puerto Rico, marks Rivian’s first steps in its broad plan to utilize second-life batteries for a wide variety of applications.
Rivian CEO RJ Scaringe and elite climber Alex Honnold will discuss the project in Denver, Colorado on June 15 at 6PM MT. The conversation will be moderated by endurance athlete and podcaster Rich Roll. The livestream can be found here: https://www.youtube.com/c/RivianOfficial/live
The company is using 135kWh battery packs from its development vehicles to support the project.
Rivian has designed its pack, module, and battery management system to seamlessly transition from vehicle energy storage to stationary energy storage at the end of their vehicle life. The battery module’s thin design enables second-life applications that are space-efficient and customizable, important for environments with existing infrastructure.
“Second-life batteries are a big enabler to accelerating widespread adoption of renewable energy, and it’s exciting to envision this system contributing importantly to a community. This project allows us to model a customized energy storage solution that takes into account space constraints, disaster resiliency and energy independence,” said Scaringe.
Adjuntas is a city of 20,000 in midwestern Puerto Rico. It was severely impacted by Hurricane Maria in 2017, and with climate change increasing the frequency and severity of storms, Adjuntas NGO Casa Pueblo has sought to collaborate on rugged, affordable sources of community power.
The Honnold Foundation and Rivian battery engineers visited Casa Pueblo earlier in 2019 to meet with community leaders and together are designing a site-specific system that will power many of the businesses located in the Adjuntas town square. In power loss scenarios, the downtown solar microgrid will allow Adjuntas residents access to electricity for core businesses. By offsetting day-to-day electric bills, the system also brings down high commercial energy costs, which in Puerto Rico are twice the national average.
The system is expected to launch in 2020.

Tesla faces Full Self-Driving pushback in EU over ‘speeding’
A new report from Reuters claims that a transport authority in Sweden is pushing back against the approval of Tesla’s Full Self-Driving suite because it will travel over speed limits.
The report says the Swedish Transport Administration (TRV) recommends the European Union votes against FSD’s approval. TRV believes it should not be approved until Tesla disables FSD’s ability to speed.
TRV sent a letter to the European Union’s Technical Committee on Motor Vehicles (TCMV), which is set to meet on June 30 to discuss the potential approval of the Tesla FSD suite in the country. Tesla, which has received various approvals in Europe over the past two months, has not provided a comment.
Teslas operating on FSD do travel over the speed limit, depending on the Speed Profile that is chosen. Drivers have the ability to disengage FSD at any point; Tesla specifically states that those supervising the suite are responsible for its actions.
Let’s cut to the chase: humans operating any vehicle speed almost daily in the United States. Realistically, speed limits in the U.S. are more frequently treated as speed minimums. However, other countries are different, and driving behaviors are less aggressive.
TRV believes that “allowing automated systems to systematically exceed legal speed limits…risks undermining both the legal framework and the expected safety benefits of vehicle automation,” the report stated. It’s surprising that Tesla has not received this claim from other countries previously.
This could be a good argument to bring Max Speed back, the setting that previously allowed the driver to choose the absolute fastest the car would travel.
This would still put the responsibility of supervision in the hands of the driver. It would allow the driver to choose whether the car would travel over the speed limit or not, acknowledging that they set the speed, and if they get pulled over, there would be no ability to argue it.
However, it does not seem as if this is something Tesla will do, especially considering many U.S. drivers have requested the feature in an effort to eliminate speeding or at least tone it down. The company has not shown any interest in bringing it back.
Tesla has approvals for FSD in Europe in Estonia, Lithuania, Denmark, the Netherlands, and Belgium.

Tesla teases greater Grok FSD integration and ‘Banish’ feature ‘in about 3 months’
Tesla is going to let you guide Full Self-Driving with Grok in 3 months, CEO Elon Musk confirmed on X.
The response from Musk, which revealed Tesla plans to allow drivers to effectively control the car and its navigation more explicitly using Grok, puts the feature for about September.
A Tesla owner said that Full Self-Driving is great, but owners should be able to “converse with Grok like we can with an Uber driver.” She then used examples like, “Grok, turn right here,” and “Drop us off right here, we’ll walk due to traffic,” and finally,” Drop at entrance first, then park far away.”
Coincidentally, the final piece of dialogue would also mean features like Banish are potentially on the way soon.
This functionality will be there in about 3 months or so
— Elon Musk (@elonmusk) June 18, 2026
Banish is also referred to as “Reverse Summon,” and would enable the car to self-park while dropping occupants off at their destination.
This would be a great way to improve the overall experience while supervising FSD. Navigation is already a major painpoint that many owners complain about. Manual overrides when a maneuver is requested or canceled (like using the turn signal stalk to override a navigation route), do not always work.
The feature could be especially useful in street parking scenarios in a city, where spots are sometimes tough to come by. Many of us who grab dinner in a more populated area will park a street or two over from wherever we’re going, because sometimes you know that’s the best you will get. If a driver using FSD could say, “Hey Grok, turn right here on Queen St. and park in that open spot on the right,” it could save a lot of confusion FSD might have on its own.
Musk teased that a similar feature was “coming” back in February:
Tesla Full Self-Driving set to get an awesome new feature, Elon Musk says
It is certainly surprising that Tesla is doing it at this point. The company’s more recent moves have been more evident of taking control and inputs away from humans and putting them in the AI’s hands more frequently. The biggest example of this was taking away Max Speed in AI4 cars, giving us Speed Profiles, and not having any input on the fastest speed the car will travel.
Of course, giving navigation preferences to Grok is availble already in Teslas, but not at the drop of a hat. Instead, you can suggest a certain route at the beginning of your drive.
Here’s an example of that from December:
🚨🏈 I am taking my parents and Fiancee to the @Ravens game next weekend and asked @Grok to help me route my @Tesla through a specific neighborhood to reach the correct Lot we will park in.
This is a great example of the new @grok nav integration with the Tesla Holiday Update: pic.twitter.com/rPp4I7q8Yv
— TESLARATI (@Teslarati) December 13, 2025
Finally, the original post that Musk responded to mentioned a parking preference after dropping off the occupants, which describes the Banish feature that Tesla has teased for years.
We’re not sure if Musk was responding more to the ability to guide the car with Grok, or whether he also was including Banish in the three-month prediction timeframe.

Tesla Cybercab has one important piece that AI4 cars might need for FSD
A close-up image of a Cybercab engineering vehicle in Peabody, Massachusetts, reveals a compact triangular side repeater camera housing equipped with an integrated washer mechanism.
This seemingly small hardware addition could prove to be one of the most critical components for achieving reliable, unsupervised Full Self-Driving (FSD) — not just for the dedicated Robotaxi but potentially for existing AI4-equipped vehicles as well.
The washer system’s importance cannot be overstated in Tesla’s vision-only autonomy approach. Cameras are the sole sensory input for the neural networks powering FSD, constantly interpreting the environment for safe navigation. In real-world conditions, however, lenses quickly accumulate rain, snow, mud, dust, or road spray.
Many of us Tesla owners, especially those who deal with any sort of winter weather at all, know the all-too-common alert that pops up when cameras are obstructed:

Even brief obstructions can drop perception confidence, trigger safety disengagements, or force the vehicle to pull over, although these are relatively rare. Instead, most of the time, the camera will need a wipe from the owner next time they stop the car.
But unlike human drivers who can manually clear their view, a Robotaxi operating 24/7 without a steering wheel or mirrors must maintain pristine vision autonomously. The Cybercab’s side repeater washer delivers targeted cleaning bursts precisely where needed for merging, lane changes, and blind-spot monitoring — functions that demand uninterrupted visibility from the external cameras:

This hardware directly tackles a known pain point in current FSD deployments. Owners frequently report camera-related alerts during inclement weather, which is understandable, but needs to be solved for a true autonomous experience.
For a production Robotaxi fleet aiming for high utilization and minimal downtime, robust washer systems represent a foundational reliability upgrade; essentially, they’re a must-have. Early sightings suggest the design may extend to rear cameras as well, creating a comprehensive cleaning architecture that keeps the entire vision suite operational in harsh environments.
Without it, even the most advanced neural nets struggle when their “eyes” are compromised.
What Does This Mean for AI4 Cars?
This Cybercab detail raises timely questions for AI4 cars already on the road. While Hardware 4 delivers superior compute and camera resolution compared to earlier versions, production models typically lack dedicated side and rear washers. Tesla has included them on Model Y robotaxis that it is using in the fleet:
Tesla Robotaxi has a highly-requested hardware feature not available on typical Model Ys
As Tesla refines unsupervised FSD for broader release, the gap in environmental resilience becomes evident. Software improvements can help mitigate issues, but they cannot fully replace physical cleaning in heavy rain or muddy conditions. Analysts and owners increasingly speculate that AI4 vehicles may eventually require similar washer retrofits — or a future AI4.5 variant — to match the Cybercab’s all-weather readiness and support the same level of autonomy.
As testing progresses, the Cybercab’s washer mechanism highlights Tesla’s pragmatic focus on real-world robustness. It may well become the hardware piece that determines how quickly and reliably FSD scales from prototypes to everyday vehicles.
