Claim 11:
12. An automotive power system comprising:
a high voltage electrical bus network configured to receive electrical energy from a generator in mechanical communication with an internal combustion engine, wherein the high voltage electrical bus network is in electrical communication with both a low voltage electrical bus network configured to charge a low voltage battery via a first output of a converter, and a secondary electrical bus network configured to, at a same time as the charge, provide electrical energy to a catalytic thermal regulator via a second output of the converter, wherein the converter is configured to receive power at an input different than the first and second outputs;
a pump configured to receive electrical energy from one of the low voltage electrical bus network and high voltage electrical bus network, to pump coolant between the pump and a high voltage battery in electrical communication with the high voltage electrical bus network; and
a controller programmed to,
in response to a catalyst temperature being within a first predetermined range, command the converter to provide a first electrical parameter to the secondary bus, and
in response to the catalyst temperature being within a second predetermined range, command the converter to provide a second electrical parameter to the secondary bus.
