Abstract
Systems and methods for operating a hybrid vehicle are presented. In one example, electric current may be supplied to or withheld from a positive temperature coefficient (PTC) heater and an electrically heated catalyst. In particular, electric current may be delivered to the PTC heater and withheld from the electrically heated catalyst, or vice-versa, in response to a catalyst temperature and battery state of charge.
