Recent personal observations and reports from many online have highlighted a concerning issue with Tesla’s V2 Superchargers. The images below I took from Supercharger locations in Kill Devil Hills, NC, and Rocky Mount, NC, show deteriorating cables. This problem is particularly prevalent in V2 Superchargers, which utilize older passively-cooled cables compared to the more advanced liquid-cooled cables found in V3 Superchargers.
Technical Differences and Current Issues
The V2 Superchargers, introduced in 2017, offer a maximum charging capacity of up to 150 kW. However, these chargers use air-cooled cables, which, over time and with frequent use, have shown signs of wear and tear. The images show cables with visible signs of damage, which could potentially lead to safety concerns and charging inefficiencies.
In contrast, V3 Superchargers, launched in 2019, boast a charging capacity of up to 250 kW. They are equipped with liquid-cooled cables, which are thinner, more flexible, and significantly more durable. This advanced cooling system not only improves the efficiency of power delivery but also reduces the risk of cables overheating and deteriorating prematurely.
The Importance of Upgrading
As the electric vehicle market grows, the demand for reliable and fast charging infrastructure becomes increasingly critical. The visible degradation of V2 Supercharger cables underscores the need for Tesla to accelerate the upgrade of these units to the more robust and efficient V3 Superchargers. Upgrading to V3 not only addresses the immediate issue of cable deterioration but also reduces charging times and allows non-Tesla EVs to make use of the charging network.
Future Prospects and Industry Impact
Tesla’s continued innovation in charging technology is pivotal for maintaining its leadership in the EV market. The introduction of V4 Superchargers, which can potentially offer up to 350 kW of power output, further emphasizes the importance of upgrading older infrastructure. Ensuring that the charging network remains in top condition is essential not just for Tesla owners but also for the broader adoption of electric vehicles.
