The invention discloses a multi-scene high-voltage throw load test system for an electric vehicle. The multi-scene high-voltage throw load test system comprises a tested working circuit of the electric vehicle, a data acquisition system and an upper computer, a tested working circuit of the electric automobile comprises a power battery, a driving motor, a plurality of high-voltage loads, a power battery on-off control switch A, a driving motor on-off control switch B, a plurality of high-voltage load on-off control switches G and a test circuit on-off control main switch C; the data acquisition system is used for acquiring real-time voltage and real-time current information of each branch in the tested working circuit and then sending the real-time voltage and real-time current information to the upper computer; and the upper computer is connected with the data acquisition system and is used for testing different load throwing scenes. According to the invention, various load throwing scenes can be simulated,
