No. It doesn’t.

Your display says that. And your display is bullshit.

I work with the people that make the displays man. There are entire groups dedicated to deciding what is indefensible lies, and what “could be true under the right circumstances so we’re allowed to say/show that”

> Why are you talking about charging from 0 to 100 % when that's NOT how you charge an EV,

lol, go to a charging station sometime and see the people sleeping or watching tv. If it’s your primary vehicle and you want to go somewhere, you are going from 0 to 100.

> Your display says that. And your display is bullshit.

I don't know what to tell you. I drive a MG4 with a 64 kWh battery. My average consumption is usually between 14-15 kWh/100 km (I don't drive very fast on freeways), which means that a full battery gets me a bit over 400 km, which is the actual range I can get fro the car. It charges at 135 kW for a large part of the battery capacity and 20 minutes of charging gives me more than 50 % of the capacity, hence more than 200 km.

I live in Prague, Czech Republic, in Europe. I don't see people sleeping or watching TV at charging stations, because there's a ton of them and they're in convenient places. I have never waited for an empty spot, not a single minute. I park my car on the street, I'm entirely reliant on public infrastructure and it works well.

My EV is my only vehicle and I only charge it to 100 % when I need the battery to balance (which my car only does at 100 %), i.e once every month or so. Again, with a working charging network and a reasonably modern EV, you can just start driving and charge when necessary (for 15 minutes or so).

fwiw this just depends a lot on the OEM. All OEMs have a non-trivial mapping of assumed energy content to shown percentage, in part because that's just not trivial to do, in part psychology. (The same is true for fuel gauges). Some brands manipulate the consumption numbers a lot (iirc - Tesla fudges the numbers the most e.g. they don't count energy consumption when not moving).

For most the consumption of an EV is shown rather accurately and is really just (energy drawn from the HV battery as measured by the BMS, which is generally very accurate for safety reasons) divided by (kilometers driven in the current interval).

As far as I know nobody includes charging losses in the readout. Personally I think this is correct for range estimation purposes. If you're swinging at a cost perspective, this of course means you're going to always miss around 3-20% depending on charging method, temperatures, car model etc. (there are fairly significant differences in OBC efficiency across models and also across AC power, low power charging gets inefficient quickly, while 7-11 kW often gets you north of 90%. DCFC is usually more efficient accounting-wise, because fast chargers bill for DC energy, not AC energy, so DC conversion losses aren't on the bill in the first place, though I assume DC chargers are also more efficient at power conversion than OBCs in general).
