Channel No.: 8 channels
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.



Applicable Batteries:  
Battery cells of Li-Ion, polymer, Ni-MH, Ni-Cd, etc.

• Each channel is equipped with a dedicated processor to ensure a perfect level of capacity calculation, timing, voltage and current control.
• All channel is under isolated test, it can directly test the cells of the battery pack.
• Independent heat source channel, temperature control and speed regulation fan.
• The LED light indicates the running status, testing status, matching status, alarm status.
• Fully compatibility with the batteries of Li-ion, Polymer, Ni-MH, NiCd, and so on.
• Fully compatible installation with cylindrical, pouch, prismatic batteries.
• Online test between computer and device, the setting and result is particular and plentiful,
• With the work steps of Constant Current Discharge, Constant Power Discharge, Constant Resistance Discharge, Constant Current Charge, Constant Voltage Charge, Constant Current & Voltage Charge, Internal Resistance Test and Idle, etc.
• Work step automatically switching.
