Abstract
A trailer battery charge system for an electrical connection device between a vehicle and a trailer. The trailer battery charge system generally includes a first switching device that allows current to flow to an electrical terminal associated with a trailer battery of the trailer. A voltage sensor generates a voltage signal based on a voltage at the electrical terminal associated with the trailer battery. A control module controls the first switching device to charge the trailer battery based on the voltage signal.
