Greetings all,

Has anyone using EA experienced lower charging speeds at chargers at sub 40°F temperatures? I pulled up to a 350kW charger, battery at 9% and preheated to 101° ready to go, started getting 95kW and then barely pulled 140kW for like 5 minutes while at 20% SoC. It then went right back down to 101kW when my battery was still below 50%. I then switched to a 150kW charger assuming the 350 was being unreliable and the same thing happened. Is this a thing?
(I’ve also verified my battery friendly charging has been turned off in the charging menus)

Normal I'd say plus you don't know if the EVSE was throttled by the operator for example.

be happy those are decent speeds when compared to my trip last week. the EA chargers are in a bad state of affairs.

Very similar experience when temps in the Central U.S. hovered above 0F in December 22. Would start at 45kW and not pull above 85 kW on either a 350 or 150. SOC was 12% and battery temp was 96F. I learned through Kyle on Out of Spec (YouTube) that the ABB equipment works OK in really cold temps. The new equipment by BTC Power do not.

Still, I was able to power-up and move-on thankful that the EA charging station worked at such an extreme temperature.

Yikes. Well at least I know it’s not my car that’s the problem 😅

Can only speak to IONITY in Europe but I did 3,000kms across France and the UK in the last few weeks and on the drive down never saw above 0c (32F) the entire day and was generally -3c (mid 20s F) and at every stop, 5 each way, I was getting 240-255kw straight away every single time. Battery was preheated by the PCM. The sites were quiet generally which maybe helped.

The only slow charges I saw were at Tesla sites but even then I was getting 145, against a theoretical max of 150.

In summary I think the car isn't the problem in these situations it's the charging infrastructure.

It is definitely the infrastructure and not the car.

at 0 degrees it might make a difference, I was having issues at temps only down to 38 degrees.

Interestingly enough, I went back to the same charging station, (different plug) and got a lovely 253kW. It was still 50°F outside so who knows…
