I have just returned from dealer because i was scheduling for 2 firmware updates :

recalls

Update SCU control unit, IONIQ 5 (NE EV)
Valid until: 12/31/9999
Campaign code: 21D064

service actions

Update tailgate module (CDM) control unit, IONIQ (NE EV)

Valid until: 03/23/2024
Campaign code: 20D014

I also asked about battery preconditioning and i got the answer by phone. So dealer contacted hyundai and the response was:

The battery preconditionning will come as infotainment navigation update in octomber. If the car have the required hardware it will enable preconditioning when navigating to DC charging station (on route).

I hope that it means if my car model 2022, is heating baterry after connected to DC (verified via OBDII car scanner) it is also eligible for this update and it can then trigger on route.

Yea when it's cold the charging speed is slow. from 43 kw upwards depending on temperature. These are my tests:


Hyundai Ioniq 5 and KIA EV6 have best charging speed among electric cars, but actual charging speed depends upon the temperature of the battery pack, it drops when battery pack is cold (below 15°C, 20°C and 25°C) or too hot (max module temp over 45°C). As Ioniq 5 does not preheat the battery en route to a CCS charger, charging will take more time in winter, it yet needs to be tested with battery temperatures below 10°C or 5°C. No one made such test with Kia EV6 yet.

Test results by Bjorn Nyland and James Cheung:
1C = 100A charging, up to 3C charging

minimum temperature of the battery pack
below 15°C - charging speed 70kW 726v*100A
over 15°C - charging speed 115kW 726v*150A
143kW 726v*200A LIMITED due to HVAC ON even on minimum temp 25C (COOLING NEEDED), triggers when maxtemp > 30C & HVAC ON
over 20°C - charging speed 180kW 726V*250A
over 25°C - charging speed 215kW 726V*300A
