· Product Description
Functions:
The equipment is mainly used for the hot pressing testing process of pouch cells. It performs hot pressing shaping and Hi-pot testing on the battery cells after winding/stacking. Its functions mainly include automatic loading, hot pressing shaping, Hi pot testing, automatic unloading, and information tracing.
Equipment parameters:
● Equipment dimension(L*W*H): 13000*4300*3500;
● Weight(ton): 54T;
● The pressing plate adopts the avoidance design. To prevent indentation at the avoidance position, a hot pressing paper device is used to cover the pressing plate to reduce the indentation;
● Adopting special coating treatment for hot pressing plates + lifting mechanism，preventing the cell from sticking on the top hot pressing plates；
● Parallelism of the upper and lower hot pressing plates: 0.05mm；
● Temperature speed of the hot pressing plates: from ambient temperature to 120℃，accuracy:±5℃；
● Temperature sensor detects the hot pressing temperature during the process. The temperature is controllable;
● Pressure range：10T adjustable. When it is below 5000kgf，the precision is ±100kgf；When it is between 5000kgf and 10000kgf，the precision is ±150kgf. It supports staged adjustment of the hot pressing speed;
● Integrated with short circuit testing system;
● Testing voltage：DC voltage range: 0~500V adjustable；
● Testing time: 190S；
● Testing resistance: Maximum displayed resistance value ＞9999MΩ;
● Hi-pot testing plate should be activated only when the cells are pressed tightly to prevent misalignment of outer electrodes;
● Equipment fault rate：≤2%，yield rate：≥99.5%.
