Noob question regarding supercharger

Post by sb96 » Sat Jan 02, 2021 10:33 am

Hi,

I recently got my ID3 and it's my first EV and I've a question regarding supercharging.

Yesterday I was driving on the highway and I had around 40% battery left, and I was near Ionity superchargers, so I thought I might as well stop there and get some juice.

It was around 1 degree outside, and I had been driving for about 50 minutes, but the car was only charging for about 36 kw/h. I thought it was going to be much higher, especially since it was an Ionity supercharging which supports up to 350kw/h(I know ID3 only supports up to 100kw/h).

But I thought maybe my car was cold, or the charger I was using was bad so I didn't think much more about it.

After finishing charging and getting on about my journey I was back at the charger roughly 2-3 hours later. This time I tried another charger(at the same Ionity station) and I was only getting about 37-42kw/h, even though I had 30% battery left.

The car behind me(a Hyundai something) was getting about 54 kw/h, so it doesn't seem to be any faulty charging.

Am I missing something regarding the supercharging?

It can go up to 100 if your battery level is low enough, the battery temperature is high enough, the charger unit has sufficient supply, isn’t having to charge multiple vehicles, and probably some other variables I haven’t read about...

I’ve done 4 rapid charges now, all at chargers which go up to 50, and each has been at 45-49.

My thoughts too, but it seems a little bit off IMO. Comparing Battery Life's charging speed video on Youtube to mine it seems way too low for me. At 40% battery Battery Life charged for 80 kw/h, and at 70% he charged for 51 kw/h, which is substantially higher than mine ever were.

My kw/h was just stuck at 36kw/h the first charge and the second charge was between 36-42kw/h no matter what battery % my car had.

And the charging station seemed to have sufficient supply, since at one point I was all alone at the station and was still only charging at 30-40kw/h. There was only one other car charging there at my second stop, and he drove Hyundai(maybe Kona?) and had 54kw/h.

I have used Ionity twice and both times initially got about 35 kw charging rate. The first time the charger was on free vend, I had something to eat and left it. The second time after a bite to eat, I moved the car to another charger having added 20% and it started at 72 kw charging. It maybe that charging the battery 20% warmed it up sufficiently. In both cases I had driven 165 miles at 70pmh on the motorway (Oxford to Leeds).

Yeah, cold battery might've been the cause for me too. But I'm still unsure, I had been driving for almost 50 minutes on the highway at 120km/h, should my battery not be warm by then?

So, I've been to an Ionity charger again.

But still no luck, never charges above 40kw/h. Doesn't matter for how long I've driven the car, if there's other cars charging, if its minus or plus outside or what battery % I have.

I've seen other cars(not ID3s) charging at the same Ionity station above 50kw/h, so it's not a faulty station.

Is there something wrong with the software? Is the battery in my car faulty? Is there something I'm doing wrong?

Did you try switching chargers or stopping the session and restarting after charging say 20% ? I also switched on the heating in the car when I left the car doing the initial 20% (described earlier in the thread) .
Hopefully an update will get battery heating sorted.

Yes, I've tried to switch with no luck... Hopefully this will get fixed in the ME2.1 update, because this is really bad...

So, after some more digging I now know why ID3 charges slowly.

It's extremely hard to get the battery warm.

This very good and informative video from Nextmove explains everything. It's a German channel but subtitles are in English:


Key takeaways:
-ID3 with no heat pump is in some situations better at managing heat/battery consumption than an ID3 with heat pump.
-To get 100KW/H at an Ionity charger you will need to warm the battery by driving fast. Approximately driving 150km/h for 95km.

Why can't the ID.3 pre-heat the battery in anticipation of rapid charging - like a Tesla? Seems weird that VW's premier entry into the EV market is missing such basic stuff! And as to the heat pump being worse than a resistive heater? WTF. I paid over a grand for this! And I did it based on VW graphs that showed up to 30% better efficiency with cars fitted with the pump.
