Abstract
A method for controlling a low-voltage circuit of a vehicle having a generator includes monitoring operating conditions of the vehicle and determining whether surplus generator load is available. Available surplus generator load is captured and used to power the low-voltage circuit. The low-voltage circuit may include a low-voltage battery, which may be charged with the surplus generator load. The surplus generator load may be utilized for anti-sulfation of the low-voltage battery. The method is usable with both a hybrid vehicle and a conventional vehicle. The method may further include powering the low-voltage circuit with energy stored in the low-voltage battery as a result of charging the low-voltage battery with the surplus generator load.
