The invention relates to the technical field of automobile cranes, and in particular relates to an electric energy management system of an electric automobile crane. The system comprises a power management module HCM, a power protection distribution module PDM, an upper drive system, a power battery management system BMS, a chassis motor PE0 and a chassis engine ECU. The SOC signal output end of the power battery management system BMS is connected with the SOC signal input end of the power management module HCM, and the control signal output end of the power management module HCM is connectedwith the upper drive system, the power protection distribution module PDM, the chassis motor PE0 and the chassis engine ECU. The power transmission end of the power protection distribution module PDMis connected with the power transmission ends of the upper drive system, the power battery management system BMS and the chassis motor PE0. Electric power guarantee is provided for continuous work ofan upper operation system, meanwhile, the lowest fuel consumption is achieved, the working condition of an engine is changed under the driving working condition, and the working condition proportion in an economic area is increased.
