Hi!

We have had very cold weather for the past week (down to -34c). I have noticed that my Zoe takes only a couple of kw power at the beginning and only warms the battery. This can be 1-2 hours. Only after that the charging power increases and battery starts to actually charge properly.

This has had such an effect to the timing that the battery is not full after the charge schedule. I can confirm this by looking at the battery temperature and power curve.

I have adjusted the charging percentage to compensate this but it's not optimal. I was thinking that if I could adjust the starting time by a static value I could get the actual powerful charging time to match the best hours.

If this value would be a input_number I could modify it dynamically based on temperature.

never mind. I managed to create automation which changes Charging speed when temperature changes
