Hyundai IONIQ 5: 10 to 80% DC Fast Charging in Freezing Temperatures

From Plug and Play EV.

Hot on the heels of our warm weather DC fast charge test of the new Hyundai IONIQ 5, we had a chance to test the car in freezing conditions… the joys of early spring in Boston!

This video contrasts our results at 70°F / 21°C — watch that one here: — with a notably longer session in temperatures around 18°F /- 8°C.

The Torque Pro readings offer some insight into how long it takes the battery heater to get the pack closer to a desirable temperature, though we’ll need to do more testing to understand whether Hyundai’s "Winter Mode" does much to help the IONIQ 5 out when the mercury drops.

Let us know what you think about the results. Is this something Hyundai should prioritize or just an inevitable outcome when trying to DC fast charge a cold-soaked battery pack?
