Why does charging from 30% to 100% take so long?


Think of your battery like a movie theater. At first, it’s empty. People can easily find a seat with little to no delay. But as it gets fuller, it’s harder for people to find an open seat. So it takes them longer to find a seat, push past everyone else, and sit down.

I’d only go to 100 if I absolutely needed it to make it to my next stop. Most road trips I’ve done, stops are often only about 110 miles apart, so frequent stops with lower charging percentages result in less time spent charging.

Yup, I was just testing to see how long it would take. I only had the car for 2 weeks.

@Zion
Yeah, going from 80 to 100 takes super long and it degrades the battery. Totally not worth it unless you need it to reach the next charger.

Really should never go above 80 with DC unless you have no choice.

Also using a 350kw for that long is a dick move. With the Niro I try my hardest to stick to 150kw stations.

The station is less than 5 minutes away from my house. I’m not going to drive 20 minutes to find a slower charger. Also, like I said in the post, I’ve only had the car for about 2 weeks and wanted to see what it’s like to charge to 100%.

The higher the charge level of the battery, the slower it charges.
Unless you’re using a slow charger, it really does slow down when using faster chargers.

Every day is a school day.

That’s really good for less than 2 mins of charging.

LOL, bruhhhhhhh. I’ll edit it.

Not sure how hard you are driving. I get 255 in 35f + weather on the highway and 300 in town.

Dayum.

All depends on speed and ambient temp. Cruising at a steady, low speed (30-50mph) in mild weather will result in max range. Air resistance (thus consumption) goes up dramatically with highway speeds.

350kW means nothing with that car, the peak charging speed is 75kW. Plus, as everyone else told you, charging over 80% on a DC charger is a waste of time due to the charging curve.

I guess it’s my fault for not saying that I already KNEW it would slow down the charge in the last 20%, since I thought everyone already knows this. What surprised me was just HOW long the last 20% took. IDK why I can’t edit the post.

230 miles at 100% is atrocious.

That Kia had 5-7 year old technology. It was excellent when new, especially for the price.

Atrocious is the solterra/bz4x/rx whatever/EV6 GT getting that number as a new car.

(Yes, I’m aware of the GT performance)

@Mica
Selling legacy technology in a 2021 car is diabolical. Who in their right mind would support this?
