Slow DC charging in my EV every morning!

[NickelBoy]

Anyone else notice a dip in DC charging speed during cold weather? Just topped up my EV at a familiar Instavolt on my way back home. Normally, I get 40+ kW/h there, but this time it maxed out at 20 kW/h.

Car said it was -1.5°C the whole trip, but shouldn't the battery management sort things out for both driving and charging in the cold? Curious if this is a common problem or something specific to my car.

Could there have been a power surge or something affecting the charging station?

Climate control feature can help with this. Did you make use of this feature or anything with the same effect?

AC charging is generally slower than DC fast charging, so the charging speed difference might not be a significant concern for you. Plus, with a 7 kW charger, you should have plenty of range added overnight, making a faster charger potentially unnecessary.

I'm curious, though. Why do you choose to charge all day once a week instead of spreading out the charging sessions more frequently? This might help you optimize your charging costs and avoid potential peak hour surcharges.

Have you noticed if the charging speed improves once the battery warms up, or does it stay slow throughout the charging session? It might be the battery temperature affecting the performance.
