  • Tesla Accelerates Supercharger Installations with New Foundation

    Tesla Accelerates Supercharger Installations with New Foundation

    Key Takeaways

    1. Tesla is increasing the construction of charging stations using a new, cost-effective foundation solution.
    2. The new installation method uses polypropylene housing, allowing faster setup without concrete foundations.
    3. This approach reduces costs by up to 70% compared to competitors and speeds up the installation process.
    4. The method also allows for quicker repairs of damaged Supercharger stations, supporting Tesla’s commitment to rapid restoration.
    5. The innovative solution contributes to reducing the CO2 footprint of the charging infrastructure.

    Tesla is ramping up the construction of its charging stations and the repair or installation of Supercharger piles using a new foundation solution.

    Prefabricated Units and Their Benefits

    Previously, the company used a Prefabricated Supercharger Units (PSU) approach, where they shipped ready-made piles with all the electrical wiring on a concrete slab. This method allowed Tesla to set up Supercharger stations in just days rather than weeks, and it was significantly cheaper—up to 70% less than competitors. This cost-effectiveness has helped Tesla win numerous federal and state contracts for public charging infrastructure subsidies.

    Faster and More Efficient Installations

    Now, Tesla aims to speed up the process even further. As Max de Zegher from Tesla emphasizes, the electric vehicle charging infrastructure must grow 30 times larger. To achieve this, the company has developed a new method for installing or replacing Supercharger stalls that eliminates the need for concrete foundations or for transporting prefab units from its Buffalo, NY factory.

    The new solution involves a polypropylene housing that a single person can easily place in a dugout and then secure with gravel. According to de Zegher, this approach “reduces C02 footprint, is faster, and reduces cost.”

    Responding to Damage Promptly

    This innovative installation method could also facilitate quicker repairs for damaged piles. With Elon Musk’s increasing political activism, there has been a rise in vandalism and arson against Tesla’s vehicles and charging stations. Tesla has committed to replacing any burned or damaged Supercharger stations within 48 hours, and they have successfully met this goal so far.

    The polypropylene housing filled with local gravel may prove useful not just for new installations but also for repairing or replacing piles, depending on the level of damage sustained by Tesla’s charging stations.

  • Huawei’s Liquid-Cooled EV Supercharger Excels in Desert Tests

    Huawei’s Liquid-Cooled EV Supercharger Excels in Desert Tests

    Huawei recently revealed the outcomes of rigorous temperature testing for its liquid-cooled supercharging technology in China's Turpan region, an area famous for extreme heat. The evaluations were conducted in the blistering Kumtag Desert and Huoyan Mountain, where ambient temperatures hit 49.6°C (121.28°F) and surface temperatures exceeded 80°C (176°F).

    Despite these punishing conditions, Huawei's supercharging technology showed impressive performance. The system maintained noise levels at 44.1 dB in standby mode and 59.5 dB while charging, even when ambient temperatures were as high as 47.1°C (116.78°F). This indicates the technology is sufficiently quiet to avoid being bothersome in everyday use.

    Efficient Heat Dissipation

    The standout feature of the system is its sophisticated liquid cooling technology, which efficiently dissipates the heat generated during charging, thus preventing overheating and potential malfunctions. Huawei also emphasizes its "precise temperature control algorithms," which are vital for sustaining system stability and charging efficiency.

    Additional testing was carried out on 414 vehicles, delivering a cumulative 13,391 kWh of energy. These tests were nearly flawless, with almost every vehicle achieving full charge in a single attempt.

    Market Implications

    As the electric vehicle sector grows rapidly, the need for fast and efficient charging solutions like Huawei’s becomes increasingly critical. The EV charging infrastructure is expected to receive substantial investment, with over $12 billion projected for the US market alone by 2030. Huawei's technology could be instrumental in this expansion.

    Future Prospects

    It’s crucial to note that this technology is still in its nascent stages. Specific details regarding real-world deployment, exact charging speeds, and compatibility with various electric vehicle models remain undisclosed.

    While these tests provide an encouraging glimpse into the future of EV charging, further information is needed to fully assess Huawei's supercharging solution.
