Abstract
According to some embodiments, a start-stop system for a vehicle is disclosed. The start-stop system includes a first energy storage device coupled to a starter motor. The start-stop system also includes a first DC-to-AC inverter coupled to the first energy storage device, a starter/alternator coupled to the first DC-to-AC inverter, and a second DC-to-AC inverter coupled to the starter/alternator. The start-stop system further includes a second energy storage device coupled to the second DC-to-AC inverter. The start-stop system finally includes a controller configured to control the two DC-to-AC inverters such that either the starter motor or starter/alternator starts the vehicle based on the state of charge of the second energy storage device.
