I can see that pre heating would give improved charge time and improved longevity of the batteries life but not range.
Is this maybe a typo from Volvo?
As it is written it implies that If you charge a battery to 90% with a preheated battery you will get more from that 90% than 90% that was charged without heating. This would mean 90%s are not all equal …
Maybe they are assuming that you will immediately use the car while the battery is warm …perhaps if you stick the car in a garage after a 90% charge that 90% becomes 89 or something?
What am I missing. My background is physics but I am not an electrical engineer and physics has also moved on since college

- Preheating of the battery when charging to 90% and 100%, gives improved range. No preheating when charging under 90%.
