Thinking of using a Tesla Supercharger for your Hyundai or Kia? Hold on a moment! While it seems convenient, you might not be getting the quickest charge. Let's dive into why, and how you can save time at the charging station.
It's true: Hyundai and Kia EVs now come with the Tesla-style charging port, opening up access to Tesla's extensive Supercharger network. But, here's a surprising twist: using these chargers might actually slow down your charging speed.
Let me explain, because understanding this can save you precious minutes when you're on the go. Imagine this: you're driving a brand-new Kia EV9, a fantastic car that can charge incredibly fast. But, you're frustrated because charging feels like a hassle. The culprit? The charging station itself.
The Quick Charge Conundrum
Hyundai and Kia's latest EVs, built on the E-GMP platform, are designed for rapid charging, often exceeding 200 kW. Some models, like the Ioniq 5, can even reach over 260 kW! The higher the kW, the faster the charge, right?
But here's where it gets controversial: Tesla Superchargers, while widespread, might not deliver these speeds. In tests, the 2024 Kia EV6 only reached 97 kW on a Tesla charger, less than half its potential. The Ioniq 5 and Ioniq 9 are limited to around 126 kW on Superchargers.
Why the Slowdown?
The issue lies in voltage. E-GMP cars operate at 800 volts, enabling faster charging and efficiency. Tesla Superchargers, however, typically use 500 volts. While Hyundai and Kia vehicles have voltage boosters to adapt, it's not a perfect match.
The Solution: Seek Out the Right Chargers
To get the fastest charge, look for chargers that support 800-volt charging. Electrify America stations are a great option, especially those rated at 350 kW. The growing network of Ionna Rechargeries is also a good bet.
The Time Savings
How much time can you save? It's significant! Under optimal conditions, the Ioniq 5 with the larger 84 kWh battery can charge from 10% to 80% in just 20 minutes. At a Supercharger, that stretches to 30 minutes. The Ioniq 9, with its bigger battery, goes from 10% to 80% in 24 minutes on the right charger, but takes 40 minutes at a Tesla station.
The Bottom Line
While Tesla Superchargers offer convenience, they might not always be the fastest option for your Hyundai or Kia. Choosing the right charger can make a big difference, especially on long trips or when you're in a hurry.
