High-power simulation battery

The utility model relates to the technical field of simulation batteries, and discloses a high-power simulation battery, which aims to solve the technical problem that the existing simulation battery cannot meet the test requirement of a high-capacity battery, and comprises a power output unit and an output synchronous following unit, and the power output unit comprises a power output circuit. The power input end of the power output circuit is connected with the power output end of the output synchronous following unit, the power output circuit is provided with a discharge power adjusting tube, and the output synchronous following unit performs dynamic adjustment output according to a voltage difference signal between the input end and the output end of the discharge power adjusting tube. Therefore, when the output synchronous following unit is adjusted according to the voltage difference of the adjusting tube in the power output unit or works at a fixed voltage, the fixed voltage is maintained all the time,
