1. A system, comprising:
a voltage converter to adjust a voltage from a first battery to a first setpoint;
a second battery having a lower voltage than the first battery, the second battery electrically coupled between the first battery and one or more loads; and
a processor coupled with memory, the processor to:
detect a first event at the one or more loads;
responsive to detecting the first event, adjust the first setpoint to a second setpoint to power the one or more loads;
detect a second event at the one or more loads;
responsive to detecting the second event at the one or more loads, compare a state of charge of the second battery to a threshold;
determine not to adjust the second setpoint from the first setpoint for the second event based on the comparison indicating the state of charge of the second battery exceeds the threshold;
identify a type of the one or more loads;
compare the type of the one or more loads to a table including identifications of different loads of an electric vehicle and a power requirement for each of the different loads;
retrieve the power requirement for the one or more loads based on the comparison to the table; and
determine the second setpoint based on the retrieved power requirement for the one or more loads;
using the second setpoint by the voltage converter to adjust the voltage of the second battery.
