摘要:
An apparatus comprises a series switching logic 202 configured to receive an input signal. When the series switching logic receives the input signal, the series switching logic transmits an output signal. The apparatus further comprises a relay control switch 204 configured to receive the output signal from the series switching logic and configured to activate a series-parallel relay 108. When the output signal from the series switching logic is received, the relay control switch activates the series- parallel relay that configures a first battery 104 and a second battery 106 between a series and parallel connection. The series switching logic is further configured to detect the presence of an external power source or an on-board generator, and the series switching logic is precluded from transmitting the output signal to the relay control switch when an external power source or on-board generator is detected.

According to one embodiment, an electrical system (100) comprises a generator (120; 130), a battery (140), and a regulator (150). The generator (120; 130) is operable to provide electrical energy at a plurality of voltage levels. The battery (140) is in electrical communication with the generator (120; 130). The regulator (150) is operable to compare a charge level of the battery (140) to a reference charge level, determine a voltage level for the generator (120; 130) based on the comparison, and provide a signal indicative of the determination toward the generator (120; 130).
