Drive to work today, the battery consumption on ABRP was way off. It’s normally very accurate but on my way to work I had to pull over and reset my SOC multiple times. In the end I gave up and just drove with it saying “route no longer viable”. I arrived at work at 10% SoC but ABRP was adamant I was at -20%.
