I5 has an 800v battery, and it can take up to 240 kW. I've never seen rates over 120kW IRL. According to this article: https://electronics.alibaba.com/buyingguides/ioniq-5-charging-speed-guide-real-world-dc-home-rates

"Approaches and Differences: DC Fast Charging vs. Level 2 Home Charging

There are only two meaningful charging approaches for the IONIQ 5—and they serve fundamentally different needs: 🔹 DC Fast Charging (10–80% Recovery)

Pros: Adds 100 miles in ~5.8 minutes 1; supports peak rates up to 235–240 kW 1; compatible with NACS and CCS networks.
Considerations: Requires specific infrastructure (not all “fast chargers” deliver >150 kW); long-term battery health benefits from varied charging patterns; fees vary widely by network.
When it’s worth caring about: You drive >300 miles/week, take multi-state trips, or lack reliable home charging.
When you don’t need to overthink it: You commute under 40 miles/day and charge overnight—DC speed has zero impact on your routine.

🔹 Level 2 Home Charging (Overnight Replenishment)

Pros: Predictable, low-cost, grid-friendly; full 84.0-kWh charge in ~7h 20m at 11.5 kW (48A circuit) 2; no subscription or app required.
Considerations: Requires 240V circuit installation (cost: $500–$1,200); slower than DC by orders of magnitude; limited by household panel capacity.
When it’s worth caring about: You own your home or have landlord approval; you want full control over timing and cost.
When you don’t need to overthink it: You rent and rely on public Level 2 (e.g., apartment complex or office chargers)—just confirm the outlet is J1772 and rated ≥32A.

" So yeah 1500kW is a tad beyond that.
