Claim 9:
10. A method for an electric vehicle capable of being used with a first type of electrical energy source and a second type of electrical energy source, comprising:
detecting, by a vehicle system manager, the presence or absence of a signal from the second type of electrical energy source via an electrical energy source communication system;
generating, by the vehicle system manager, a type signal that indicates the first type of electrical energy source if a signal is not detected via the electrical energy source communication system, or the second type of electrical energy source if a signal is detected via the electrical energy source communication system;
using, by the vehicle system manager in response to the type signal indicating the first type of energy source, electrical energy source information from a vehicle mounted electrical energy source status determining unit coupled to the first type of electrical energy source; and
using, by the vehicle system manager in response to the type signal indicating the second type of energy source, electrical energy source information from an energy source mounted electrical energy source status determining unit,
wherein:
the vehicle mounted electrical energy source status determining unit is configured to determine an energy depletion of the first type of electrical energy source, and
the energy source mounted electrical energy source status determining unit is configured to determine an energy depletion of the second type of electrical energy source.
