Abstract
The product is used for lithium battery formation, capacity sharing and performance parameter testing. The master-slave battery comprehensive testing system composed of computer and equipment single chip microcomputer has advanced structure, reliable performance, convenient operation, high efficiency and high cost performance. It is an indispensable production and testing equipment for lithium battery manufacturers, capacity sharing manufacturers and scientific research units.
Structure and appearance of equipment
The equipment structure is mainly composed of the following parts:
1.One CPU board, the whole cabinet is sent for control.
2.There are 64 eight channel constant current plates, which are evenly arranged
in four doors.
3.There are 32 charging switching power supplies with two constant current boards
for each.
4.Two keyboard boards, front and back operation.
5.The height of the battery supported by the clamp can be adjusted from 10 to
100 mm, and the width of the battery is within 32 mm. The battery can be round
or square
