I own a SR+ with LFP battery
I own a SR+ with LFP battery in Europe and the charging speeds went up after an update from 30kW to 100kW with my car. The range issues it has when the weather is colder is really awful though.
I received my car mid-December 2020 and can only drive it for 175-200 km per full charge when below 10 C. Above 10 C it goes up to 250 km. When above 15 C it seems to go up to 300 km.
When fully charged it states 416 km of range. I know that is WLTP so not real.
When talking to Tesla engineers they told me that range will improve in coming updates though.
I calculated one time what I lost in kW from the battery that was not used for driving. It was about 10kW when it was below 10 C. So I believe this is leaking away towards the heater. Unfortunately my car was build without the heat pump, so it eats up a massive amount of my range.
Still happy with the car though. :)
