The Tesla Super Fast Charger uses DC charging technology, which can provide high-power DC fast charging service for Tesla vehicles. The charging pile in the supercharger station converts alternating current in the grid into direct current, which is then delivered to the vehicle battery pack through the charging port for fast charging. The power of the Tesla Super Fast charge can reach 250 kilowatts, which can charge the vehicle in a short time, greatly reducing the charging time.
In fact, it is because Tesla's unique charging pile uses an adjustable DC voltage power supply method, and the input is three-phase and four-wire alternating current, which can directly charge the battery of the electric vehicle without additional equipment, which is still somewhat different from the AC charging pile.
The latter uses the on-board charger to achieve the purpose of charging, limited by the power of the on-board charger, so the charging speed naturally drops.
