technical field [0001] The invention relates to the field of high-voltage thermal batteries, in particular to a device for detecting that the high-voltage thermal battery can withstand backfilling energy. Background technique [0002] During the working process of the electromechanical servo, the electromechanical actuator has two working states of the motor and the generator, and the two interact. The electromechanical actuator works in the state of the motor, and the servo driver performs inversion processing on the direct current of the thermal battery, drives the electromechanical actuator to push the nozzle to do work, and directly converts the electrical energy into the mechanical energy of the nozzle. When the motor is working, the electromechanical actuator consumes electric energy, and the thermal battery must meet the instantaneous peak current of the electromechanical actuator and the steady-state load maintenance current demand. When the electromechanical actuat...
