1. A hybrid power system, comprising:
a computing core;
a power converter, coupled to the computing core;
a driving motor, coupled to the power converter;
an engine generator, coupled to the power converter;
a charging stand, coupled to the power converter; and
a battery pack, coupled to the power converter,
wherein an electric energy source is coupled to the charging stand and provides power to the battery pack through the power converter in case of inputting a required torque to the computing core and switching to a charging mode, wherein the computing core executes an optimal power allocation algorithm,
wherein the optimal power allocation algorithm establishes a four-loop formula and conducts a global search for a total required power, a total required current, and a power ratio, further using a global grid search method to calculate a plurality of minimum power consumption of all conditions and outputting a multi-dimensional table.
