The Tesla charging system is three-phase. Tesla electric vehicles use three-phase AC charging technology, which usually uses single-phase AC for home charging, but in Tesla's Supercharger charging station, three-phase AC can be provided to charge faster. Three-phase charging can provide higher power and faster charging speed, which is very useful for long trips or situations where charging is urgently needed. As a result, Tesla owners can choose from different kinds of charging devices for fast and efficient charging according to their needs.
