  • Tesla Model Y Juniper: 20-Year Lifespan Outshines Diesel Cars

    Tesla Model Y Juniper: 20-Year Lifespan Outshines Diesel Cars

    A recent study from the UK titled “the closing longevity gap between battery electric and internal combustion vehicles” suggests that concerns regarding the lifespan of electric vehicles (EVs) may be exaggerated.

    Improved Lifespan of Modern EVs

    The research indicates that earlier issues with electric cars, which led to more frequent repairs and shorter lifespans, have been largely resolved in today’s EVs. Their lifespans are now similar to those of gasoline cars, even when used more heavily. This is particularly evident for Tesla vehicles, with some models having already reached over 400,000 miles. Researchers noted, “Tesla’s EVs are expected to cover an average of 204,000 miles over their lifetime, surpassing all other brands regardless of powertrain.”

    Tesla vs. Other Brands

    When calculating the average expected lifespan of Tesla cars, the study found it to be 20.3 years, which is longer than both petrol and diesel vehicles. Among diesel cars, VW’s Skodas are predicted to last the longest at 17.4 years, but they will cover less distance than Teslas. For gasoline vehicles, Audis might last 20.9 years, slightly exceeding Tesla’s lifespan, though they typically have much lower usage, about 143,100 miles.

    Future Considerations for EV Longevity

    However, researchers warn that the electric vehicle sector is still quite new, and the costs of battery replacements need to decrease to truly take advantage of their extended technological lifespan. They stated, “To fully realize the benefits of a longer BEV lifespan, replacement batteries, if necessary, must be affordable relative to the residual value of BEVs without their original batteries.” As of 2020, the price for battery replacement ranged from US$4,000 for a 30 kWh Nissan battery to US$10,275 for a 75 kWh Tesla Model 3. In contrast, ICE vehicle transmission replacements cost between US$1,100 and US$3,400. If battery prices do not decline in a timely manner, owners may decide to dispose of their BEVs prematurely, which could distort comparisons of longevity with ICE vehicles.

    Advancements in EV Warranties

    Taking this into account, both electric vehicle and battery manufacturers are pushing for longer warranties to enhance the second-hand market. Companies like NIO and CATL are striving to establish a standard 15-year battery warranty, increasing from the current average of eight years.

    The technology behind battery cell chemistry has matured to the point where CATL can provide such warranties for swap stations or commercial batteries. If a 15-year warranty for EVs becomes common, the findings of this vehicle longevity study—suggesting that new Teslas, including the forthcoming Model Y Juniper, could last for 20 years—might signal a promising trend for the future.

  • Chargie: Boost Your Laptop Battery Lifespan Efficiently

    Chargie: Boost Your Laptop Battery Lifespan Efficiently

    Batteries naturally decline in their ability to hold a charge as they age. Operating systems like Windows and macOS already include various tools designed to help prolong battery life. Chargie aims to simplify the process of safeguarding laptop batteries. This compact device plugs into the USB-C charging port and connects to the laptop’s charging cable. There are also adapters for Dell, HP, and Lenovo laptops that use a traditional hollow plug rather than USB-C.

    Features and Functionality

    Chargie works with chargers that have an output of up to 100 watts. Once it’s connected, the device must be paired with the laptop via Bluetooth to set it up using its dedicated software. The application is compatible with Windows, macOS, and Chrome OS, allowing users to limit the maximum battery charge to a specific percentage, such as 80%. This helps to extend battery life, as fully charging or depleting a battery can cause additional strain.

    While it’s possible to achieve similar results through software alone, Chargie provides extra functionalities. It enables users to set charging schedules and monitor as well as limit the current charge rate. The concept is that slower charging generates less heat, which in turn protects the battery cells. As a result, charging may take a longer time. An update anticipated in the second quarter of 2025 will allow Chargie to also be used with smartphones.

    Pricing and Risks

    At present, Chargie is being funded through a Kickstarter campaign, where it can be pre-ordered under the “Early Bird” deal for $40. After this initial offer, the price will increase to $49. The expected delivery date is February 2025, with the prices not covering shipping and import taxes. As is common with crowdfunding initiatives, there are inherent risks: products may not arrive, or they might be of subpar quality if issues arise during production.
