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 improving Giga Berlin’s free “Giga Train” service for employees
With this initiative, Tesla aims to boost the number of Gigafactory Berlin employees commuting by rail while keeping the shuttle free for all riders.
Tesla will expand its factory shuttle service in Germany beginning January 4, adding direct rail trips from Berlin Ostbahnhof to Giga Berlin-Brandenburg in Grünheide.
With this initiative, Tesla aims to boost the number of Gigafactory Berlin employees commuting by rail while keeping the shuttle free for all riders.
New shuttle route
As noted in a report from rbb24, the updated service, which will start January 4, will run between the Berlin Ostbahnhof East Station and the Erkner Station at the Gigafactory Berlin complex. Tesla stated that the timetable mirrors shift changes for the facility’s employees, and similar to before, the service will be completely free. The train will offer six direct trips per day as well.
“The service includes six daily trips, which also cover our shift times. The trains will run between Berlin Ostbahnhof (with a stop at Ostkreuz) and Erkner station to the Gigafactory,” Tesla Germany stated.
Even with construction continuing at Fangschleuse and Köpenick stations, the company said the route has been optimized to maintain a predictable 35-minute travel time. The update follows earlier phases of Tesla’s “Giga Train” program, which initially connected Erkner to the factory grounds before expanding to Berlin-Lichtenberg.
-->Tesla pushes for majority rail commuting
Tesla began production at Grünheide in March 2022, and the factory’s workforce has since grown to around 11,500 employees, with an estimated 60% commuting from Berlin. The facility produces the Model Y, Tesla’s best-selling vehicle, for both Germany and other territories.
The company has repeatedly emphasized its goal of having more than half its staff use public transportation rather than cars, positioning the shuttle as a key part of that initiative. In keeping with the factory’s sustainability focus, Tesla continues to allow even non-employees to ride the shuttle free of charge, making it a broader mobility option for the area.

Tesla Model 3 and Model Y dominate China’s real-world efficiency tests
The Tesla Model 3 posted 20.8 kWh/100 km while the Model Y followed closely at 21.8 kWh/100 km.
Tesla’s Model 3 and Model Y once again led the field in a new real-world energy-consumption test conducted by China’s Autohome, outperforming numerous rival electric vehicles in controlled conditions.
The results, which placed both Teslas in the top two spots, prompted Xiaomi CEO Lei Jun to acknowledge Tesla’s efficiency advantage while noting that his company’s vehicles will continue refining its own models to close the gap.
Tesla secures top efficiency results
Autohome’s evaluation placed all vehicles under identical conditions, such as a full 375-kg load, cabin temperature fixed at 24°C on automatic climate control, and a steady cruising speed of 120 km/h. In this environment, the Tesla Model 3 posted 20.8 kWh/100 km while the Model Y followed closely at 21.8 kWh/100 km, as noted in a Sina News report.
These figures positioned Tesla’s vehicles firmly at the top of the ranking and highlighted their continued leadership in long-range efficiency. The test also highlighted how drivetrain optimization, software management, and aerodynamic profiles remain key differentiators in high-speed, cold-weather scenarios where many electric cars struggle to maintain low consumption.
Xiaomi’s Lei Jun pledges to continue learning from Tesla
Following the results, Xiaomi CEO Lei Jun noted that the Xiaomi SU7 actually performed well overall but naturally consumed more energy due to its larger C-segment footprint and higher specification. He reiterated that factors such as size and weight contributed to the difference in real-world consumption compared to Tesla. Still, the executive noted that Xiaomi will continue to learn from the veteran EV maker.
“The Xiaomi SU7’s energy consumption performance is also very good; you can take a closer look. The fact that its test results are weaker than Tesla’s is partly due to objective reasons: the Xiaomi SU7 is a C-segment car, larger and with higher specifications, making it heavier and naturally increasing energy consumption. Of course, we will continue to learn from Tesla and further optimize its energy consumption performance!” Lei Jun wrote in a post on Weibo.
-->Lei Jun has repeatedly described Tesla as the global benchmark for EV efficiency, previously stating that Xiaomi may require three to five years to match its leadership. He has also been very supportive of FSD, even testing the system in the United States.

Elon Musk reveals what will make Optimus’ ridiculous production targets feasible
Musk recent post suggests that Tesla has a plan to attain Optimus’ production goals.
Elon Musk subtly teased Tesla’s strategy to achieve Optimus’ insane production volume targets. The CEO has shared his predictions about Optimus’ volume, and they are so ambitious that one would mistake them for science fiction.
Musk’s recent post on X, however, suggests that Tesla has a plan to attain Optimus’ production goals.
The highest volume product
Elon Musk has been pretty clear about the idea of Optimus being Tesla’s highest-volume product. During the Tesla 2025 Annual Shareholder Meeting, Musk stated that the humanoid robot will see “the fastest production ramp of any product of any large complex manufactured product ever,” starting with a one-million-per-year line at the Fremont Factory.
Following this, Musk stated that Giga Texas will receive a 10 million-per-year unit Optimus line. But even at this level, the Optimus ramp is just beginning, as the production of the humanoid robot will only accelerate from there. At some point, the CEO stated that a Mars location could even have a 100 million-unit-per-year production line, resulting in up to a billion Optimus robots being produced per year.
Self-replication is key
During the weekend, Musk posted a short message that hinted at Tesla’s Optimus strategy. “Optimus will be the Von Neumann probe,” the CEO wrote in his post. This short comment suggests that Tesla will not be relying on traditional production systems to make Optimus. The company probably won’t even hire humans to produce the humanoid robot at one point. Instead, Optimus robots could simply produce other Optimus robots, allowing them to self-replicate.
-->The Von Neumann is a hypothetical self-replicating spacecraft proposed by the mathematician and physicist John von Neumann in the 1940s–1950s. The hypothetical machine in the concept would be able to travel to a new star system or location, land, mine, and extract raw materials from planets, asteroids, and moons as needed, use those materials to manufacture copies of itself, and launch the new copies toward other star systems.
If Optimus could pull off this ambitious target, the humanoid robot would indeed be the highest volume product ever created. It could, as Musk predicted, really change the world.
