Abstract
Method and apparatus are disclosed for determining and controlling a vehicle load current and temperature through the use of a common current sensor. An example vehicle includes a power source, an electrical sensor configured to detect a total current provided by the power source to a plurality of electrical loads, and a processor. The a processor is configured to determine a target load temperature based on the total current, and set a voltage duty cycle of the target load to maintain the target load temperature.
