Guess I'm in the minority. For me theLEAF's percent display is the only non-BS battery metric on the car. Having it increase slightly on a long regenerative downhill run is not confusing -- it's expected. Certainly far more useful and better-behaved than the psychotic Guess-o-meter, or the "guess-a-width" battery bars. Give the rubes their DTE meter with big, friendly numbers, and the psychologically manipulated "bars", but please, PLEASE let me have a simple non-obfuscated representation of the remaining energy in the pack.

I agree with Nubo here. It always annoys me to see newbs to Leafs and Bolts get so confused about the guess-o-meter and "why does my car only charge up to x miles?" "I used up 40 miles of range going 25 miles on the highway..."

On WetEV's posts, I agree with points 1 and 3 thru 5. It's annoying that the Bolt has no % SoC display in the car's own UI but rather only 20 battery bars. At least GM put in marks at 1/4, 1/2 and 3/4 but I have to count how many bars I am above 75% or below it or above 50% or below it. Fortunately, someone else (here?) gave me the hint that the My Chevrolet app on Carplay actually DOES have a % SoC display that will be displayed on the car's LCD. I knew the app had it but it was slow to update (just about as slow or slower than NissanConnect) when not connected via CarPlay. But, when connected via CarPlay, it self-updates fairly quickly.

3) Bolt has no battery temp display anywhere. I will have to get the Torque app and proper OBD2 dongle sometime.
4) After getting a Bolt, I can confidently say that anywhere except for the center of the nose of an EV is an sub-optimal position for the inlet now.
5) Like the UI on my '19 Bolt that lets me have charging stop at 40 to 100% in 5% increments.

I don't mean to shoot the messenger but to me, the ONLY useful measurement of capacity and thus range on my BEV Leafs is SOC% :) I mean Nissan seems to have learned their lesson, not having it on their first gen Leafs('11-'12) but adding it in '13 and on, you'd think other mfgs. would have learned from Nissan's mistake but no, like many other things in this world, people just don't learn from history :(
I mean how many people do you know who don't have SOC% enabled on their cell phones? No one I know of, not even sure you can disable SOC% on an android phone but on an Apple It's the first thing I do after taking it out of the box, enable SOC% :)

Agreed, the car battery is managed much like a cell phone battery as a user/driver. Think about it, you charge up every night and leave in the morning with a full charge. Not so true with an ICE.

The SOC display rarely if ever varies by temperature, at least not by more than 1%, and the only time it varies by grade is when the latest Nissan Bug kicks in on a 40kwh Leaf. None of the previous Leafs get confused or deceptive about SOC when climbing a hill. I'm guessing that, having only just learned about this feature, you are throwing excuses at the wall, to see what sticks. ;)

You got that backwards. Manufacturers are too nieve to know what customers want. Remember the LEAF started with no SOC meter? That was a fail. Nissan added it and how many have complained? No one...

Manufacturers have mistakenly taken the longer range as the reason why SOC meter is no longer needed which is incredibly stupid. We have 400 mile gassers that run out of gas every hour of every day despite the nice little gauge...

When the BMW i3 came out (shipped in Europe before the US), it also had no % SoC display. I don't recall if this applied to the BEV or REx or both. Folks complained loudly to no avail. BMW gave some goofy excuse along the lines of (IIRC), we think our GOM is good. :roll: Not sure if they've fixed that deficiency since then.

Yet many new EVs have the charging port someplace other than the center of the nose.

Why?

The Hyundai Kona Electric seems to slightly to the left facing forwards. I'm not sure that this is a problem, clearly better than on the side.

Sticking it in the fender is cheaper. I suspect that the Leaf position has remained in the nose mainly because of the heavy Chademo cables.

120 Amp cable is a 120 Amp cable. CCS or Chademo, no difference.
