Abstract
A powertrain includes an engine and an electrical circuit having a motor-generator and a starter mechanism coupled to the engine. A first energy storage device is disposed in a parallel electrical relationship with the starter mechanism. A second energy storage device is disposed in a parallel electrical relationship with the motor-generator. A first auxiliary electric system is disposed in a parallel electrical relationship with both the first energy storage device and the second energy storage device. A first switch is disposed within the electrical circuit between the first energy storage device and the first auxiliary electric system. A second switch is disposed within the electrical circuit between the second energy storage device and the first auxiliary electric system. The first auxiliary electric system is disposed, within the electrical circuit, between the first switch and the second switch.
