1. A multi-power system for providing electrical energy to a load unit, said multi-power system comprising:
a fuel cell unit including a fuel cell, and a first conversion module that is electrically connected to said fuel cell and that is to be electrically connected to the load unit;
a lithium-ion cell unit including a lithium-ion cell, and a second conversion module that is electrically connected to said lithium-ion cell and said first conversion module and that is to be electrically connected to the load unit; and
a control unit electrically connected to said first conversion module and said second conversion module, and storing a power optimization data sheet that includes a plurality of power parameter sets, each of the power parameter sets including a power setting value, a first optimal power, and a second optimal power, said control unit being configured to switchably operate among a first mode, a second mode, a third mode, a fourth mode, and a fifth mode, wherein said control unit is configured to,
when operating in the first mode, control said first conversion module to draw electricity from said fuel cell at a maximum power and to output the electricity to the load unit and said second conversion module, and further control said second conversion module to output the electricity received from said first conversion module to said lithium-ion cell so as to charge said lithium-ion cell,
when operating in the second mode, control said first conversion module to draw electricity from said fuel cell at a first predetermined power that is lower than the maximum power and to output the electricity to the load unit,
when operating in the third mode, control said first conversion module to draw electricity from said fuel cell at a predetermined low power, control said second conversion module to draw electricity from said lithium-ion cell at a second predetermined power, and control said first conversion module and said second conversion module to cooperatively output the electricity drawn from said fuel cell and said lithium-ion cell to the load unit,
when operating in the fourth mode, control said first conversion module, said second conversion module, and the load unit to stop operating, and
when operating in the fifth mode, select one of the power parameter sets as a selected set, control said first conversion module to draw electricity from said fuel cell at the first optimal power included in the selected set, control said second conversion module to draw electricity from said lithium-ion cell at the second optimal power included in the selected set, and control said first conversion module and said second conversion module to cooperatively output the electricity drawn from said fuel cell and said lithium-ion cell to the load unit.
