Pulse formation and grading technology adopts periodic pulse current (including forward and reverse pulses) to realize fast and accurate capacity testing and sorting. Its dynamic feature of short-time pulse plus standing depolarization conforms to the law of ion migration, reducing energy loss and structural damage of cells.
Equipment Features
● Pulse Width: 20ms~500ms
● Pulse Current Range: 0.5C~3C
● Charge-Discharge Rise Time: 3ms
● Charge-Discharge Switching Time: 5ms
● Working Mode: Positive Pulse, Negative Pulse
Technical Advantages
● Reduce polarization and temperature rise, inhibit lithium precipitation, and improve cell safety and yield rate
● Optimize SEI film performance, greatly enhance cell cycle life and consistency
● Support high-current formation & grading, shorten working hours and improve production line energy efficiency
● Higher testing accuracy with better effect on cell sorting and grouping
● Lower energy consumption and less heat dissipation pressure
