Abstract: An automatic mounting and demounting device and system for a motor testing platform, adapted to enable a control host to control automatic mounting and demounting between an axle of a motor under test and an axle of a testing apparatus, includes a mobile platform and a positional information sensing member. The control host controls the mobile platform according to positional information generated by the positional information sensing member, such that a carrier for carrying the motor under test is automatically driven to a corresponding position to thereby effect alignment and connection or separation of the axle of the motor under test and the axle of the testing apparatus. Therefore, preparation for the motor dynamics testing is automatically carried out effectively and correctly, thereby reducing the time and manpower required for testing-related preparation.

Abstract: A method is provided for testing a semi-finished battery cell. The semi-finished battery cell is charged with a constant current when a voltage difference between the first conductor and the second conductor is less than a voltage threshold. The semi-finished battery cell is charged with a constant voltage when the voltage difference between the first conductor and the second conductor is equal to or larger than the voltage threshold. An overall electric quantity is obtained after a default time period, wherein the overall electric quantity is an electric quantity charged to the semi-finished battery cell with the constant current during the default time period. Accordingly, an insulation related to electrodes of the semi-finished battery cell is determined as poor when the overall electric quantity is larger than an electric quantity threshold.
