1. A vehicle comprising:
a power converter having first and second outputs and configured to receive power at an input different than the first and second outputs;
a low voltage battery configured to receive power from the power converter via the first output;
a heating element configured to receive power from the power converter via the second output, and to provide heat to a catalyst of an exhaust system; and
a controller programmed to command the converter to provide power to the heating element via the second output according to a temperature of the catalyst such that a value of the power provided to the heating element via the second output increases as the temperature decreases.
