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.

Abstract: A probe includes a first electrical conductor, a second electrical conductor and a voltage measurer. The first electrical conductor has a first through hole, and the first through hole extends through two ends of the first electrical conductor. The second electrical conductor is detachably disposed on the first electrical conductor, and the second electrical conductor has a working surface and a second through hole. The working surface is located at an end of the second electrical conductor away from the first electrical conductor. Two ends of the second through hole that are opposite to each other are located at the working surface and an end of the first through hole, respectively. The first through hole is communicated with the second through hole. The voltage measurer is penetrating through the first through hole and the second through hole.
