Over the weekend I decided to put my 2018 LX HEV into sport mode to charge the battery to 100% so I could find out exactly what the all electric range is.

Once the battery was 100% charged, it drove completely different. There was ZERO engine braking when letting off of the throttle. It was easy to keep the instant MPG gauge in the 50+ mpg area when driving in Sport mode, and it was VERY difficult to prevent the car from using electric assist.

So I started driving with the battery at 100%. The average speed was 30 mph and I hit 6 stop lights. At 7.1 all electric miles the gas engine cranked up. This really surprised me.

That is pretty amazing range from such a small battery. Of course, the HEV software normally won't let the battery get that high or low, so most users probably won't see more than a mile or so pure EV. I know when I drove my son-in-law's '18 Ioniq it was next to impossible to keep the ICE from firing up with even the gentlest of starts.

One can charge the battery to 100% using sport mode? You have the HEV, right?
You say the ICE came on at 7.1 miles. What was the battery level at that point? 50%? Zero?

In order to get the battery to 100%, you need to monitor power flow and use the sport mode to manually shift in order to keep the battery charging. At about 75%-80% of the battery being charged, it appears as though the computer cuts back how much it charges the battery. So once you get above this point it gets harder and harder to try to keep the power flow meter in the charging mode.

You will know you are at 100% charge when the battery level indicator is full, but the best way to tell is when you get zero engine braking.

According to the battery level indicator, the ICE kicked back on when the battery was down to about 20%.

And yes, my Niro is an HEV LX model.

Likely you mean no regen braking, or 100% engine braking with foot off pedal.
Both. When the battery is fully charged you can let off the gas and it is like cruise control is turned on. You don’t slow down at all. That is not an exaggeration either. You also have to get on the brakes harder as you have zero regen braking. This gave me a good idea of when the service brakes start to be used under normal driving conditions.

My first go at charging via Sport mode didn't work. But I see this post now, it doesn't just happen with time, but that I need to coax it by manually shifting. So should I shift to lower gears (higher revs) to coax it then? Granted I wouldn't be looking to do this but rarely, more just curious. And maybe if I was planning to go up a long hill at high speed and wanted to maintain good power/acceleration.

What on earth is the point of burning gas to charge your battery? Very inefficient and costly. You can instead use that gas in the engine to propel your car directly at a much higher efficiency.

Obviously the point is not about saving fuel. The point was to test to see what the range of the tiny battery pack is on the HEV model. It was not an efficiency test, just a range test. Since my Niro is an HEV model, the ONLY way to charge the hybrid battery is to use the ICE to do so.
