The invention discloses a multi-load wireless electric energy transmission system with constant current-constant voltage output. The multi-load wireless electric energy transmission system comprises an electric energy sending end and a plurality of electric energy receiving ends, the electric energy transmitting end is formed by sequentially connecting a DC power supply, a full-bridge inverter and an LCC-S type compensation network; and the electric energy receiving end is formed by sequentially connecting a receiving side compensation network, a rectifier bridge and an electric energy output end. According to the invention, switching from a constant current output mode to a constant voltage output mode can be realized through simple frequency switching, which is beneficial to simplifying control of the system; meanwhile, the constant current-constant voltage output switching method provided by the invention is suitable for the multi-load wireless power transmission system, the input impedance angle of the system is 0 in a constant current (constant voltage) working mode, the reactive component of the system is less, and the efficiency is high; in addition, additional switching devices do not need to be added, and miniaturization and light weight of a wireless electric energy transmission system of the underwater vehicle are facilitated.
