The 2025 Hyundai Ioniq 5 surprised with a charging speed of 126 kW at a Tesla Supercharger, lower than its typical maximum speed.
Despite using a Tesla V3 Supercharger, the Ioniq 5's charging speed was lower than expected due to changes in plug type.
The Ioniq 5's charging experience at a Tesla station revealed differences in plug compatibility and voltage levels.
The Ioniq 5's charging session from 24% to 80% at the Tesla Supercharger took 28 minutes and added 50 kWh of energy.
Hyundai will release an over-the-air update to improve charging speeds on the Tesla network in the coming months.
The transition to Tesla's charging network for non-Tesla EVs poses challenges but opens up access to over 17,000 Tesla Superchargers in the U.S.
Improvements to Tesla's infrastructure, including V4 Supercharger stations, will support higher-voltage EVs like the Ioniq 5.
Although charging speeds may not meet owners' expectations, the NACS charging for the Ioniq 5 is described as decent and preferable to other options.
The engineering manager at Hyundai expects faster charging speeds on the Tesla network and believes the charging curve of the Ioniq 5 still compares favorably to Tesla models.
Owners of the 2025 Hyundai Ioniq 5 using Tesla Superchargers should be aware of the differences in charging dynamics and the upcoming improvements to enhance charging performance.
