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: An electrical probe includes a probe assembly and a second electrical connection member. The probe assembly includes a needle cylinder, a first electrical connection member, a probe head and a sub-probe. The first electrical connection member and the probe head locate to two opposite sides of the needle cylinder. The first electrical connection member and the probe head electrically connect the needle cylinder. The sub-probe penetrates the probe head, and plugs the needle cylinder to electrically connect a cable but being electrically isolated from the needle cylinder. The sub-probe is located on a side away from the first electrical connection member. When the probe head depresses the object, the needle cylinder drives the first cylinder to a contact position to allow the first electrical connection member to electrically contact the second electrical connection member, and thus the probe head connects the second electrical connection member via the needle cylinder.
