Hybrid power system and energy management optimization method thereof

An energy management optimization method of 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 the energy management optimization method comprises:
• in case of a required torque detected by the computing core being 0, switching the hybrid power system to a standby mode;
• in case of the hybrid power system being switched to a charging mode,
• inputting a required torque to the computing core and determining whether the required torque is greater than 0, wherein
• when the required torque is 0, the hybrid power system is switched to the standby mode;
• and
• when the required torque is greater than 0, the computing core of the hybrid power system 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.
