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 stock tumbles after earnings, one of its sharpest single-day declines
Tesla stock (NASDAQ: TSLA) endured one of its sharpest single-day declines in years on July 23, tumbling approximately 14.5 percent and closing near $320 after opening the session around $374. The drop erased more than $140 billion in market value amid heavy trading volume and left the shares at multi-week lows.
The sell-off followed the company’s second-quarter 2026 results, released the previous evening. Tesla reported record revenue of $28.2 billion, up 26 percent year over year, driven by a Q2-record 480,126 vehicle deliveries. Energy storage deployments also rose strongly.
Tesla (TSLA) Q2 2026 earnings results: miss on EPS, beat on revenue
Yet profitability disappointed sharply. Operating income fell 57 percent to $398 million, compressing the operating margin to just 1.4 percent. Non-GAAP earnings per share came in at $0.33, well below the roughly $0.53 analysts had expected. Free cash flow turned negative by $1.1 billion as capital expenditures surged 142 percent to $5.8 billion, largely tied to accelerated spending on artificial intelligence, robotics, and autonomous systems.
The losses on capex were expected, as Tesla said it would be spending heavily in 2026.
Investors also reacted to lingering uncertainty surrounding key product timelines. During the Earnings Call, management reiterated ambitions for Robotaxi deployment and the Optimus humanoid robot, but offered limited new concrete milestones, renewing questions about execution pace that have long accompanied Tesla’s ambitious roadmap.
The magnitude of the decline places it among Tesla’s more severe one-day percentage losses since its 2010 initial public offering. Historically, the two largest single-day drops (split-adjusted) remain September 8, 2020, when shares fell 21.1 percent amid broader market volatility and valuation concerns, and January 13, 2012, with a 19.3 percent plunge during the company’s early growth struggles.
Other notable declines include an 18.6 percent drop on March 16, 2020, at the onset of pandemic-related market turmoil. Thursday’s move ranks roughly ninth on the all-time list but stands out as the steepest in more than a year.
Despite the short-term pain, Tesla’s long-term trajectory has repeatedly recovered from such volatility. The latest results underscore both the strength of its core automotive and energy businesses and the near-term costs of heavy investment in next-generation technologies.

Elon Musk is not happy about this Tesla Full Self-Driving approval delay
Elon Musk clapped back at France’s decision to withhold the approval for Tesla’s Full Self-Driving (FSD) Supervised system, projecting a clear and blunt message to French Transport Minister Phillippe Tabarot, after he publicly rejected the technology in its current form.
Tabarot outlines several concerns with Tesla Full Self-Driving in a detailed video statement, where he said, “The safety trade-offs are not yet sufficient to authorize it as it currently stands,” he said. He emphasized that FSD is not a true self-driving system and that the driver remains fully responsible.
Key issues Tabarot also brought up included allowing speeding when surrounding traffic exceeds limits and what he believes are insufficient guarantees of driver attention during complex urban maneuvers such as lane changes, intersections, and roundabouts.
Delaying the approval of FSD in France will cost lives

While acknowledging technological progress and France’s support for autonomous innovation, Tabarot stressed that deployment must prioritize road safety. He noted ongoing technical discussions with Tesla, the Netherlands, and other European partners, with further ecosystem meetings planned for the fall.
Musk’s rebuke highlights the human cost of regulatory caution. Tesla’s latest safety reports provide compelling data supporting accelerated adoption. In the most recent 12-month period, vehicles using FSD (Supervised) recorded one major collision per approximately 5.1 million miles driven, dramatically better than the U.S. national average of one crash per 698,000 miles.
Even Tesla vehicles driven manually with active safety features outperform the average by a wide margin. These figures come from billions of real-world miles of telemetry, showing FSD vehicles involved in far fewer incidents than both manual Teslas and the broader U.S. fleet.
Critics argue Tesla’s comparisons require careful scrutiny regarding reporting thresholds and fleet demographics, yet the data consistently positions FSD as a potential lifesaver. With road fatalities remaining a leading cause of death worldwide, Musk contends that proven safer technology should not face prolonged bureaucratic hurdles.
France’s measured approach reflects the broader European regulatory caution, which many, especially Musk, have been critical of in the past. However, as autonomous systems from Tesla and competitors like Waymo demonstrate superior safety in independent studies, pressure is mounting for harmonized approvals.
Musk’s warning carries the belief that every month of delay may equate to avoidable tragedies on European roads.

Google’s massive stake in SpaceX will shock you
In a striking revelation that underscores the lucrative crossover between Big Tech and space exploration, Alphabet Inc., Google’s parent company, disclosed a massive $94.1 billion equity stake in SpaceX following the rocket company’s blockbuster initial public offering earlier this year.
The disclosure came in Alphabet’s quarterly filing, marking the first time the long-held private investment has been publicly valued at market prices. Google was an early backer, investing alongside Fidelity in 2015 with roughly $500-900 million at a time when SpaceX was valued around $12 billion.
That bet has delivered extraordinary returns, roughly a hundredfold, transforming a strategic play on satellite internet and launch capabilities into one of Alphabet’s largest assets.
Google, $GOOGL, has said they hold $94 billion in SpaceX, $SPCX, shares after IPO.

Of the total holding, approximately $80 billion remains subject to short-term post-IPO lockup restrictions, preventing near-term sales. An additional $14.1 billion faces longer-term restrictions, extending into the third quarter of 2027. This structure limits immediate liquidity but protects against market volatility as SpaceX transitions into public trading.
The SpaceX position contributed significantly to gains in Alphabet’s broader investment portfolio, which also includes a major stake in AI leader Anthropic. Combined, these holdings helped drive nearly $100 billion in investment gains during the second quarter, providing a substantial boost to net income amid ongoing AI spending pressures.
Analysts view the disclosure as validation of Alphabet’s venture strategy beyond its core search and cloud businesses. The investment aligns with deeper ties, including reported multi-billion-dollar deals for AI computing capacity on SpaceX infrastructure. As SpaceX advances Starship flights, Starlink expansion, and ambitious Mars goals under Elon Musk, Google’s stake positions it to benefit from the commercialization of space.
For Alphabet, the windfall highlights how patient, forward-looking bets in transformative sectors can yield outsized rewards. While lockups temper short-term impact, the holding cements SpaceX as a cornerstone of Alphabet’s diversified portfolio in an era where aerospace, AI, and connectivity increasingly intersect. Investors will watch closely as restrictions lift and SpaceX’s public performance unfolds.
