Abstract

An electric energy managing system applied to an electric vehicle, comprises the following components. A first state-of-health (SOH) calculating circuit, calculates an overall SOH of a fuel cell of the electric vehicle. The overall SOH is associated with an aging condition of the fuel cell. A second SOH calculating circuit, calculates a SOH of a lithium battery of the electric vehicle. The SOH is associated with an aging condition of the lithium battery. An electric energy distribution circuit, calculates a first predefined ratio of an output power of the fuel cell with respect to a total electric energy demand of the electric vehicle according to the overall SOH of the fuel cell and the SOH of the lithium battery, and controls a second predefined ratio of the output power of the fuel cell with respect to an output power of the lithium battery according to the first predefined ratio.
