If you currently own an electric vehicle that uses an 800-volt or higher battery architecture, such as a Hyundai Ioniq 6, Porsche Taycan, or Lucid Air, you’re able to use Tesla Superchargers with a Magic Dock and Tesla app, but you may experience slow charging speeds. Why? Currently, the Magic Dock chargers have a maximum output of 500 volts, as they were originally designed for only Teslas—which up until the Cybertruck launches, all used a 400-volt battery system like most EVs. Meanwhile, 800-volt EVs have an onboard inverter to make them compatible, but that inverter is limited by the hardware the automaker specified, which tends to be from 50 to 150 kW. This makes them unable to charge at their peak DC fast-charge rates at Tesla’s 500-volt Superchargers, whereas fast-chargers elsewhere in the public charging infrastructure, such as Electrify America, have a 1000-volt maximum.
Was curious why it was limited to 50kW. This explains it:
