Claim 17:
18. A power delivery system comprising:
an engine including an engine shaft and configured to be disposed onboard a vehicle;
an alternator mechanically coupled to the engine shaft;
a primary battery conductively connected to the alternator via at least a first switch device;
a secondary energy storage system (SESS) conductively connected to the alternator via at least a second switch device and conductively connected to the primary battery via at least a third switch device; and
a control system configured to close the second switch device to establish a conductive path between the SESS and the alternator for supplying electric current from the SESS to power the alternator to rotate the engine shaft during a cranking operation, and
responsive to the cranking operation successfully starting the engine, the control system is configured to open the second switch device and one of: (i) open the third switch device or (ii) maintain the third switch device in an open state to electrically isolate the SESS from the primary battery and the alternator, which blocks discharge of electric current from the SESS.
