1. A method of managing a vehicle electrical system, the method comprising:
identifying a current number of available battery strings associated with an energy source coupled to an electrical grid in response to detecting unavailability of one or more battery strings at the energy source;
identifying a current degradation state of a plurality of degradation states associated with the vehicle electrical system;
determining an offset for increasing a control target for the energy source based at least in part on the current number of available battery strings and the current degradation state, wherein the control target comprises at least one of a state of charge (SOC) target and a voltage target;
determining an adjusted control target for the energy source by adding the offset to the control target to increase availability of the energy source based at least in part on the current number of available battery strings and the current degradation state, wherein the adjusted control target comprises at least one of an adjusted SOC target and an adjusted voltage target;
identifying a control scheme for the energy source based at least in part on the current number of available battery strings associated with the energy source, the control scheme comprising a prioritization for alternating between different modes; and
autonomously operating the vehicle electrical system in a manner that is influenced by the adjusted control target by alternating between the different modes in accordance with the identified control scheme.
