Hyundai Ioniq 5 vs Tesla Model Y: charging compared
Charging curves overlaid, time-to-charge at every common UK charger speed, and per-network cost — modelled on each car's actual charging behaviour.
At a 150kW UK rapid (10% → 80%): the Hyundai Ioniq 5 finishes in 23m, around 8 minutes ahead of the TeslaModel Y at 31m.
The Tesla Model Y and Hyundai Ioniq 5 are the UK's bestselling and one of its most-praised electric SUVs respectively. Their charging stories are similar to the Model Y vs Kia EV6 fight — same Hyundai-Kia 800V E-GMP platform inside — but the Ioniq 5's character is different enough on the road that the comparison is genuinely independent.
Architecturally the Ioniq 5 holds its 235kW peak from around 10% SOC up to 50%, then tapers gradually. The Model Y peaks at 250kW briefly between 10-20% then steps down faster. On a 350kW charger the Ioniq 5 finishes a 10-80% top-up in similar time despite its lower peak; on the Tesla's own Supercharger network at 250kW the Model Y is competitive, particularly because the Supercharger pre-conditions the battery automatically.
At home and on 150kW chargers there's barely a difference — both are 11kW AC, both have similar real-world efficiency for an SUV of this size (~290-295Wh/mile), both deliver about 240 miles real range. Cost per mile is within a penny across most networks.
Choose the Tesla for software polish and Supercharger access; choose the Ioniq 5 for V2L bidirectional charging, more interior space and the genuine 800V advantage at ultra-rapid sites.

Time to charge by charger speed
SOC range 15% → 80%. Cells softer where the charger speed exceeds the car's peak DC — higher chargers deliver the same time.

Common questions
Does the Ioniq 5's 800V architecture make it faster than the Model Y in everyday charging?
Only at 350kW chargers. On 50kW and 150kW chargers the cars are similar. For a UK driver doing most charging at home and occasional rapid stops, the difference is small.
Can the Ioniq 5 actually do vehicle-to-load?
Yes — V2L is standard, and you can run mains-voltage appliances directly from the car (up to 3.6kW). The Model Y has no V2L feature.
Which has better real-world range?
Both around 240 miles in mixed UK driving. The Model Y is slightly more efficient (~295Wh/mile vs ~290Wh/mile) but the cars are within 5% of each other.
