Leased it back in May, and lately, my Niro’s charging speed won’t go past 23kW, even when using a CCS charger and staying below 80% charge. Any ideas what could be wrong?
Anything over 7 kWh counts as fast charging. If it’s cold outside, the battery might not charge quickly until it warms up. It could also be an issue with the charger’s cooling system, limiting its power.
Can you share more details? What was the battery level when you plugged in? What’s the charger’s power rating? And what was the temperature at the time?
This forum has a lot of posts like this you might want to check out.
- I drive about 10 minutes to reach this charger.
- It’s the same station I’ve used for months without problems. It’s rated up to 350kW, and I used to get around 70kW here.
- It’s about 37°F outside lately.

Your Niro tops out around 70-80kW, so you’re close to its maximum. To optimise charging, use the car’s built-in navigation to guide you to the station. This triggers battery preconditioning, which warms the battery as you drive there.
@TellurideTribe
Agreed. At 37°F (assuming that’s not Celsius), preconditioning would help you get faster charging right away.
@oliviamartin
How much of your driving has been sustained speeds above 70 mph?
At lower temps like 37°F, charging rates can drop significantly. Just so you know, even a 350kW charger won’t charge a Niro faster than a 150kW station because of the car’s limits.
High speeds can also impact charging performance. There are many factors at play.

I don’t drive at high speeds much. It’s a 10-minute drive to this charger, which I use because it’s nearby and part of Electrify America. I get 500kW credits with my lease.

My 2019 Niro maxes out at 76kW briefly but usually stays between 38-46kW on DC fast chargers between 20% and 80% charge. A lot of factors can slow charging speeds!
@oliviamartin
When you drive to the charger, do you use the built-in navigation to guide you there? That’s how you activate battery preconditioning, which helps a lot in colder weather.
@Kiatalks
Anything above 19.2 kWh is considered fast charging. A home AC charger can go up to 80A at 240V.

For the Niro, AC charging is limited to 7kW or 11kW (on newer models). There’s no option for anything higher in North America.
It’s probably the cold weather. It’s 37°F outside. Does the Niro have a battery preconditioning feature?

Yes, but it only works if you set your navigation to a fast charger.

I’m not sure. I can’t find any settings for it.
It’s still charging fast, but it’s not reaching its peak rate.
Is this happening only at one station, or have you tried others? Check if battery preconditioning is on:
- Go to your car’s infotainment screen.
- Open EV > EV settings > Battery conditioning mode.
- Activate the setting by ticking the box.
Preconditioning starts when you set your navigation to the charger using the built-in system. The car prepares the battery for faster charging this way.
@Austin
Got it. I’ll give this a shot next time. Thanks .
Did you check the temperature of the battery?
Same thing is happening to me now that it’s cold out. I used to fast charge around 78kW in summer, but now it barely reaches 28kW. From what others said, preconditioning only works when you use the built-in navigation to go to a fast charger, not Apple CarPlay or Android Auto.
Have you tried using the built-in navigation set to a fast charger? Did it make a difference?
