Document Type and Number:
WIPO Patent Application WO/2019/178931
Kind Code:
A1
Abstract:
The present invention relates to a method and a system for testing battery pieces of a shingled assembly. The battery pieces have a front surface and a back surface opposite the front surface, a plurality of front surface busbars extending parallel to each other being formed on the front surface, and a plurality of back surface busbars extending parallel to each other being formed on the back surface. The method according to the present invention comprises the following steps: providing an adjustable upper test device comprising an adjustable number of upper probe rows; providing an adjustable lower test device comprising an adjustable number of lower probe rows; and electrically connecting the adjustable upper test device and the adjustable lower test device to test equipment for testing, selecting, according to the tested battery pieces of the shingled assembly, the number of probe rows of the adjustable upper test device and the number of probe rows of the adjustable lower test device, so that the adjustable upper test device is located on the front surface, is in contact with the front surface busbars and is turned on, and the adjustable lower test device is located on the back surface, is in contact with the back surface busbars and a back surface field and is turned on.
