The reason your charger doesn’t stop charging is because the charger is trying to balance out the hv battery . More than likely you have one or more battery modules that are bad . The question here is when the hv battery gets down to 10 miles does the miles drop off really fast ?
The hv battery was designed when its fully charged the charger shuts off no reason to stop it from charging all the way to 50 miles . The only way to tell if a module is bad the car needs to be hooked up to the Fisker laptop and hv battery data needs to be checked. This check should also be done when the battery is low on miles .
