Abstract
A control system includes a state of charge module and a control module. The state of charge module receives a parameter associated with a battery in a vehicle and determines a state of charge of the battery based on the parameter. The control module activates a heater in a catalytic converter in an exhaust system of the vehicle based on the state of charge.
