  • Tesla Reveals Supercharger Dynamic Pricing; GM Tests NACS Ports

    Tesla Reveals Supercharger Dynamic Pricing; GM Tests NACS Ports

    Key Takeaways

    1. Tesla is expanding its EV charging network with more Superchargers, but wait times at busy locations remain an issue during peak hours.
    2. A new virtual queuing system has been trialed to manage the order of cars at Superchargers and reduce line-cutting incidents.
    3. Tesla is introducing a dynamic pricing model for Superchargers that adjusts costs based on real-time usage to manage traffic during busy times.
    4. The dynamic pricing trial is starting at ten Supercharger stations in California, ensuring prices remain stable during a charging session.
    5. Tesla’s Supercharger technology is becoming a standard for charging, with other manufacturers like Hyundai, KIA, and GM starting to adopt it.

    While Tesla continues to expand its extensive EV charging network with more Superchargers, the growth is often not rapid enough to eliminate lines and annoying wait times at busy spots during rush hours.

    New Virtual Queuing System

    Earlier this year, Tesla started a trial of a virtual queuing system designed to help cars in line based on a first-come-first-served approach. This initiative was aimed at reducing the problems that occasionally occur when someone cuts in line at the Supercharger.

    Dynamic Pricing Structure

    Now, the company is rolling out a dynamic pricing model for Superchargers to help manage traffic during peak times and promote a more balanced distribution of charging sessions throughout the day. The so-called on-peak and off-peak prices are based on real-time data rather than estimates, reflecting the actual usage of each charging station. For instance, if a popular Supercharger is unusually busy during off-peak hours, the price per kWh will increase, thereby discouraging additional drivers from charging if they can wait.

    Conversely, if a usually busy Supercharger has several open stalls at a time known for high traffic, the system will drop prices, even if it’s during a peak time. Tesla has now published a list of all Supercharger sites where this real-time off-peak pricing is in effect.

    Initial Testing Phase

    Tesla is kicking off this dynamic pricing test at ten Supercharger stations in California, with the company stating that average prices will remain quite similar, just more equitably spread throughout the day based on demand. It also assures customers that prices won’t change while charging is in progress; they will stay the same as what is shown at the start of the session, no matter if the station gets busier or not.

    This is a significant development, given that Tesla’s Superchargers have become the leading standard for charging, with almost all major EV manufacturers adopting the open-source technology. Earlier this year, Hyundai and KIA vehicles gained access, and now GM is reportedly testing vehicles with built-in NACS ports to charge directly at Superchargers without needing an adapter like the Lectron NACS to CCS kit.

    For example, the new Cadillac Optiq does not have a port for direct Supercharger access; GM is retrofitting testing vehicles to collect data on how the Tesla charging system performs under real-world conditions.

    UK Study: Electric Car Owners Save 30% on Maintenance Costs

    Key Takeaways

    1. Electric vehicle (EV) owners can save up to 30% on ownership costs compared to diesel or petrol car owners.
    2. A study found that maintenance costs for EVs are lower 95% of the time compared to similar fossil fuel vehicles.
    3. EV owners spent an average of £4,022 on servicing and repairs over five years, while traditional car owners spent £5,709.
    4. The Vauxhall Corsa Electric and Mini Countryman showed significant maintenance savings of 31% and 22%, respectively, over five years.
    5. EVs have fewer moving parts and do not require oil changes, leading to lower maintenance needs and costs.

    When individuals buy cars, they are essentially agreeing to cover maintenance expenses, which can add up. A recent study from Britain reveals that electric vehicle (EV) owners might save as much as 30 percent on ownership costs when compared to those driving diesel or petrol cars.

    Research Overview

    The Car Expert, utilizing Clear Vehicle Data, conducted a survey involving over 600 new and nearly new vehicles on UK roads in 2025. The study found that maintenance costs for EVs were lower 95 percent of the time in comparison to similar fossil fuel vehicles. On average, the research determined that EV owners spent £4,022 on servicing and repairs, while traditional cars demanded £5,709 over a five-year span.

    Specific Vehicle Analysis

    The Car Expert looked into the maintenance expenses associated with the Vauxhall Corsa Electric and the fully electric Mini Countryman. The Vauxhall Corsa Electric provided a 31 percent savings for its owners during the first three years and 32 percent over the subsequent two years. In contrast, the Mini Countryman was 22 percent less costly to maintain over a five-year duration.

    Electric vehicles have fewer moving parts compared to internal combustion engines (ICEs), which means there is a decreased chance of components failing and needing replacement. Notably, EVs do not require oil changes, which is a regular requirement for diesel and petrol vehicles.

    Conclusion from the Study

    According to the managing director of Clear Vehicle Data, “We analyze servicing costs across every possible vehicle configuration – from fuel type to body style, mileage, trim level, and more. Our findings illustrate a distinct trend: electric vehicles are consistently cheaper to maintain, and this difference stays significant through 2025.”

    4. CATL has improved shipping efficiency by reducing costs by 35% through a streamlined loading process and a 2-in-1 design that addresses transportation challenges.
    5. Enhanced safety features include advanced thermal management, gas sensors for rapid response to runaway events, and compliance with the IEEE693 standard for earthquake and storm resilience.

    Contemporary Amperex Technology Limited (CATL), recognized as the top EV battery producer globally with a 38% market share, continues to enhance and innovate its offerings.

    New Innovations in Battery Technology

    Following its introduction of the first commercial sodium-ion battery pack for electric vehicles, which boasts a range of over 300 miles per single charge, CATL has now rolled out a pioneering 9 MWh energy storage system (ESS).

    The latest Tener Stack solution utilizes CATL’s recent advancements in battery chemistry and packaging, which significantly boosts energy density and capacity, fitting into a standard 20-foot energy storage container.

    Previous Milestones

    Approximately one year ago, CATL introduced the world’s first mass-produced energy storage solution with a capacity of 6.25 MWh, named Tener. At that time, it featured a 20% reduction in size and a 30% increase in energy density compared to earlier 20-foot energy storage solutions.

    With the help of CATL’s solid electrolyte interphase and other cutting-edge technologies, the highly reactive lithium in the LFP batteries is safeguarded against oxidation, which prevents thermal runaway and slows down capacity loss. As a result, CATL was able to offer a 5-year zero degradation and a 20-year overall warranty with the Tener system, a first of its kind.

    Introducing Tener Stack

    The new energy storage solution, known as Tener Stack, retains the same zero capacity degradation warranty as its 6.25 MWh predecessor.

    CATL proudly declares, “This is the world’s first mass-produced 9 MWh ultra-large capacity energy storage system solution,” asserting that the company has made significant advancements in system capacity, safety, deployment flexibility, and transportation efficiency, heralding a new era for large-scale storage technology with the Tener Stack.

    With a 9 MWh energy storage capacity, the 20-foot container can supply power to an average single-family home for up to six years, with CATL guaranteeing the cells will not experience capacity degradation for the first five years. Additionally, it has the potential to charge up to 150 electric vehicles, based on the current average battery size. CATL highlighted this capability while showcasing the solution at the Electrical Energy Storage (EES) 2025 expo in Munich, particularly for the typical German household.

    Enhanced Design and Efficiency

    The Tener Stack system employs LFP battery cells, similar to those found in well-known mobile power stations like Anker’s Solix C1000, which is currently on sale for 50% off at Amazon. In this case, CATL has improved space utilization by 45%, resulting in a 50% increase in energy density compared to traditional 6 MWh energy storage solutions.

    This enhancement allows utilities to develop a standard grid-level 800 MWh energy storage park using fewer containers, thus requiring 40% less land for deployment. Moreover, CATL has tackled the logistical difficulties of transporting these heavy LFP battery cells.

    The new Tener system has been designed as two identical half-height units, each weighing just under 36 tons, which is the typical legal limit for heavy shipment ground transport. When they arrive, the units can be combined into a 20-foot container, which is reflected in the “2-in-1” design and the name Tener Stack.

    Cost-Effective Shipping and Safety Features

    CATL has streamlined the loading process by utilizing standard container spreaders and liners, which has reduced shipping costs by 35%. The structural 2-in-1 design also permits the Tener Stack system to be sent to hard-to-reach areas where weight limits for bridges and tunnel heights might be problematic.

    As for safety, CATL highlights the leading thermal management of its LFP batteries, alongside new gas sensors that allow for rapid response to runaway events. The upgraded insulation further enhances fire resistance. The system meets the IEEE693 standard, capable of withstanding a magnitude 9 earthquake or a Category 5 storm.

    To save space and minimize thermal radiation, the thermal management system is positioned at the top of the container. The resultant noise level is maintained at 65 dB from three feet away, making CATL’s Tener Stack ESS suitable for urban environments as well.

  • BYD Tops Tesla Sales in Europe as Vet Crushes Model 3 with Tank

    BYD Tops Tesla Sales in Europe as Vet Crushes Model 3 with Tank

    Key Takeaways

    1. Tesla’s deliveries in Europe have significantly declined, with a 46% drop in Germany and 62% in the UK compared to last year.
    2. Despite overall electric vehicle sales rising by 28% in Europe, Tesla’s market share has fallen, even in strong markets like Norway.
    3. BYD has experienced remarkable growth, with a 750% increase in sales in Germany and over 300% in the UK, surpassing Tesla for two consecutive quarters.
    4. Consumer perception of Tesla is changing, as BYD’s sales figures nearly match Tesla’s in the UK, signaling a shift in preference.
    5. A unique stunt involving a WWII veteran driving a tank over a Tesla Model 3 highlights the declining brand image and market position of Tesla.

    The forecast that BYD will outsell Tesla in electric cars this year appears to be becoming a reality.

    Declining Tesla Shipments

    In Europe, Tesla’s deliveries have hit a several-year low, particularly in key markets like Germany and the UK, even as overall electric vehicle sales are booming. In the first quarter, Tesla attributed this trend to seasonal factors and suggested that demand might be delayed due to the staggered release of their new Model Y and necessary factory shutdowns for updates.

    Now, with Tesla’s sales dropping by 46% in Germany compared to last April and a staggering 62% decline in the UK, that reasoning seems to be losing credibility. Sweden experienced an 80% fall in Tesla sales, France saw a 59% drop, and Spain faced a 36% decrease. Even in Norway, a stronghold for electric vehicles in Europe, Tesla’s share has fallen from 18% to 11%.

    BYD’s Remarkable Growth

    This decline occurs alongside a 28% rise in EV sales across Europe, with VW and BYD making notable gains. BYD’s sales in Germany skyrocketed by 750% compared to last April, despite facing a 10% general import tariff and a 17% specific tariff imposed by the EU. BYD has now surpassed Tesla in electric car sales for two consecutive quarters and is on track to potentially achieve its first full year as the leading electric car manufacturer globally by 2025.

    In the UK, BYD achieved an impressive over 300% increase in sales year-on-year last month, nearly matching Tesla’s sales figures, indicating a significant change in consumer perception of the Tesla brand.

    A Unique Stunt

    To emphasize this shift, a 98-year-old WWII veteran drove a Sherman tank over a Tesla Model 3. The spectacle involved the tank crushing the Tesla’s windshield, flattening its roof and pillars while climbing over the vehicle.

    Interestingly, the Model 3 didn’t end up entirely destroyed by the 30-ton war machine, but it was amusingly converted into a convertible, if only for a brief moment during the tank’s passage.

  • Tesla Cancels Cybertruck Range Extender and Issues Full Refund

    Tesla Cancels Cybertruck Range Extender and Issues Full Refund

    Key Takeaways

    1. Tesla has officially discontinued the Cybertruck range extender, previously priced at $16,000.
    2. The Cybertruck’s real-world driving range has faced criticism, with some tests showing less than 100 miles under extreme conditions.
    3. Initial range estimates were adjusted downward, with the maximum range now at 445 miles for the standard model.
    4. Tesla recalled all Cybertrucks made between November 2023 and February 2025 due to rim detachment issues.
    5. Customers who paid a deposit for the range extender are being offered full refunds as Tesla no longer plans to sell the accessory.

    Tesla has officially stopped providing the Cybertruck range extender, just weeks after it was removed from their website. This expensive add-on, priced at $16,000, was intended to improve the vehicle’s range performance, which has faced criticism.

    Range Performance Issues

    Reviewers have pointed out that the Cybertruck’s actual driving range can be as low as 240 miles under real-world conditions. The range becomes even less when transporting heavier loads or in cold weather. In some extreme tests, the vehicle reportedly managed less than 100 miles.

    To tackle these problems, Tesla introduced the modular Cybertruck range extender, which was an extra battery pack designed to fit in the truck’s bed. At first, it was expected to provide ranges of up to 470 miles for the dual-motor Cybertruck and 440 miles for the tri-motor Cyberbeast.

    Adjustments to Ranges

    However, those numbers were later adjusted down to 445 miles for the standard Cybertruck and 415 miles for the Cyberbeast equipped with all-terrain wheels. Compounding these issues, Tesla recalled all Cybertrucks manufactured between November 13, 2023, and February 27, 2025, because of problems with rim pieces detaching.

    Recently, Tesla quietly took the range extender off the online configuration options for the vehicle. It seems that the company has decided to abandon this accessory altogether.

    Customer Communication

    Tesla has begun reaching out to customers who put down a $2000 deposit for the add-on. They are offering full refunds, explaining that they are “no longer planning to sell the Range Extender for Cybertruck.”

    Despite its challenges, the Cybertruck has been recognized for its notable specifications and its off-road capabilities, even if it does not serve as a direct replacement for conventional pickups. The exact reasons behind the cancellation of the accessory remain unclear, and Tesla has yet to provide an official comment regarding this decision.

  • Tesla Model Y: Special APR Financing Rates Available Now

    Tesla Model Y: Special APR Financing Rates Available Now

    Key Takeaways

    1. Tesla is offering a new 1.99% APR financing rate for the 2026 Model Y Long Range AWD, aimed at enhancing affordability.
    2. Monthly payments for the AWD Model Y can start at $603 with a federal tax credit factored into the down payment.
    3. The 1.99% APR financing is available for various loan terms but cannot be combined with Tesla’s $2,000 Loyalty Incentive.
    4. A new Model Y RWD trim is introduced at $4,000 less than the AWD version, but it has a higher standard financing rate of 5.49%.
    5. The RWD variant offers the longest range among Model Y options, and lower APR financing may be introduced for this model in the future.

    After rolling out a 0% APR financing option for the Model 3, Tesla is now enhancing the affordability of the Model Y with a new interest rate offer.

    Financing Details

    While this offer isn’t as enticing as the zero APR available for the Model 3, it’s still significantly lower than the rates applied to the Model S, Model X, or even the Model Y RWD. The new deal features a 1.99% APR financing rate specifically for the 2026 Model Y Long Range AWD. This is available to eligible buyers who have a strong credit rating and requires a minimum down payment, which can be partially covered by the federal tax credit.

    Payment Options

    For the AWD trim of the Model Y, which starts at a price of $50,990 before tax credits, monthly payments can begin at $603 when utilizing the federal subsidy as part of the down payment. This option is available for the longest term of 6 years, but the 1.99% APR promotional rate is also applicable for 36-, 48-, and 60-month terms.

    However, it’s worth noting that this financing offer cannot be combined with the $2,000 Loyalty Incentive that Tesla currently provides to existing Model Y owners. Other promotions or credits from Tesla’s Refer and Earn Program can still be used alongside this new interest rate offer.

    New Model Y RWD Trim

    Tesla has also launched a more affordable Model Y RWD trim, which is priced $4,000 less than the AWD version, but it does not qualify for the 1.99% APR financing rate. Instead, the RWD variant is financed at the standard 5.49% APR, which is why the monthly payment is nearly the same as that of the dual-motor Model Y.

    The RWD trim remains a new offering that delivers the longest range amongst the Model Y options. It’s likely just a matter of time before Tesla decides to introduce lower APR financing options for this more economical Model Y as well.

  • SK On Advances Longevity of Solid-State Batteries for EVs

    SK On Advances Longevity of Solid-State Batteries for EVs

    Key Takeaways

    1. SK On is developing new solid-state battery prototypes aimed at improving resilience and lifespan compared to current electric vehicle batteries.
    2. The lifespan of electric vehicle batteries can now be extended to three times longer than the typical 100 charge cycles.
    3. A new protective layer for lithium-metal anodes was created by using a solution with lithium nitrate, enhancing battery longevity.
    4. Collaboration with Yonsei University revealed that longer curing times for protective layers can improve discharge capacity in polymer solid-state batteries.
    5. A factory for testing these innovative batteries is being built in partnership with Solid Power, expected to be completed by late 2025.

    SK On is a firm that focuses on the creation and production of electric vehicle batteries. They are currently working on two new solid-state battery prototypes that aim to be more resilient than the batteries we have today. A factory dedicated to testing these innovative batteries is under construction in partnership with Solid Power, with an anticipated completion date in the latter half of 2025.

    Improved Battery Lifespan

    Electric vehicles, like the latest Mercedes-Benz CLA, usually see their batteries lose efficiency after around 100 charge cycles. However, researchers at SK On have reportedly managed to extend that lifespan to three times longer.

    Innovative Methods

    To make this happen, the research team attempted to get rid of the protective layer on the lithium-metal anode by placing it in a solution containing lithium nitrate and other compounds. This approach inadvertently created a new, stronger protective layer.

    The development of this new layer, thanks to lithium oxide, enhances the longevity of lithium-metal batteries. SK On has shared these discoveries in the ACS Energy Letters journal (as noted by Chosun Biz).

    Collaboration with Academia

    In addition, SK On along with Yonsei University studied how the lifespan of gel polymer electrolytes correlates with their thermal stability in polymer solid-state batteries. The researchers found that a longer curing time for the cathode’s protective layer leads to a decreased discharge capacity.

    To investigate this further, they cured the protective layers of two batteries for varying lengths of time. The results showed that the battery cured for 20 minutes had a 34% drop in capacity, whereas the one cured for 60 minutes only experienced a loss of 9.1%.
