SLOW CHARGING FOR 800-VOLT EVS AT TESLA SUPERCHARGERS WITH MAGIC DOCK EXPLAINED

EV Channels Review

This video delves into the complexities of charging 800-volt electric vehicles at Tesla Superchargers using the Magic Dock CCS adapter. The primary limitation identified is the 350-amp current output of the Supercharger dispenser when using the CCS adapter, which caps charging speeds significantly below the potential of many modern EVs. While Tesla vehicles can exceed this limit due to internal communication and liquid-cooled cables, CCS-equipped cars appear to be restricted by the dispenser's nameplate rating. Additionally, 800-volt architectures (like those in Lucid Air, Porsche Taycan, Hyundai Ioniq 5, Kia EV6, and Genesis GV60) require onboard DC-to-DC boosters to step down voltage, further limiting charging speeds to around 50-100 kW depending on the vehicle's booster capacity. The reviewer highlights that while this makes Tesla Superchargers a slower option for these vehicles compared to dedicated 350 kW chargers, it serves as a valuable backup for peace of mind. The upcoming Version 4 Superchargers, with their 1000-volt capability and longer cables, are expected to resolve these issues. The Hummer EV's unique charging strategy is also discussed as an unknown factor. Overall, the video provides a clear, albeit technical, explanation of current charging limitations for high-voltage EVs on the Tesla network.
