2025 IONIQ 5 10-80% DC FAST CHARGING TEST AND ANALYSIS | CHARGE TIME HAS SLOWED...

EV Channels Review

The 2025 Hyundai Ioniq 5's DC fast charging performance is put to the test, revealing a slight slowdown compared to previous models, particularly in colder temperatures. The reviewer experienced a 2-minute increase in the 10-80% charging time, attributing it to the new NACS port and potentially the battery conditioning strategy, which appears to require warmer ambient temperatures (around 77°F) to achieve peak charging speeds above 250 kW. While the charging curve shows impressive initial speeds and a sustained 250 kW for several minutes, the stepped reductions in power are noted. The reviewer highlights that international models with CCS ports still achieve the advertised 18-minute 10-80% charge. Despite the minor slowdown, the Ioniq 5 still offers robust charging, with the reviewer planning further tests in warmer weather and exploring range testing with different wheel and tire combinations.
