So, I think it’s better if there’s a lot of experience to create your own thread. It’s all about recording how the pre-climate (heating) hits the range and the % value of the battery in the winter. Because of the different KWh/100km consumption, everyone will have a different % to km ratio, as well as there may be differences between the IV60 and IV80. So medium and large battery, I have not mentioned the small one now, but can sofe I assume that the energy spent at the beginning is high, but the longer the time it takes, the more it sinks, so that there may be a clear difference between 5 and 10 min, but between 20 and 30 min is perhaps only minimal. So far, there have been 2 data in a thread. Once an attempt by me at the IV60 without a heat pump. Duration: 6min Outside temperature: ~6 degrees Ranges Loss: 3km Battery Verl ust: 1% Interior temperature: 20.5 degrees The other user has the following values for the IV80 with heat pump. Duration: 15min Outside temperature: probably similar to ~6 degrees Ranges Loss: 1km Battery Loss: 2% Interior temperature: 21 degrees
