Lithium Battery Charge Discharge Testing and Balance Maintenance Tester-DT5050 can be used for capacity test, charge characteristic test, capacity grading and matching, balance maintenance, internal resistance test of various types of Li-ion Batteries, Ni-MH Batteries, Ni-CD Batteries. It can be compatible with cylindrical, pouch and prismatic cells. The isolation channel testing design can determine the location of the defective cells without disassembly the battery pack. Each isolation channel can independently charge and discharge the battery, maintain the balance of the battery pack, and restore the unbalanced battery pack to normal balance level.
Main Functions:
1.Capacity Testing
2.Charging Characteristic
3.Auto Cycle Charge-Discharge
4.Active & Passive Balance Repair
5.Data Grading & Matching
6.Data Analysis
It’s suitable for lithium battery testing, maintenance, battery pack assembly and EV battery repair/rebuilding, etc.
