Description
Lithium Battery Charge Discharge Testing and Balance Maintenance Machine DT50W-20 
is capable of conducting capacity tests, charge and discharge characteristic tests, capacity grading and matching, balance maintenance, internal resistance tests, data analysis & comparison, etc., for a variety of Lithium batteries, NiMH batteries, and NiCD batteries. It offers physical compatibility with 18650, 26650, 32650, 33140 cells as well as pouch and prismatic cells. With its isolation measurement design, the DT50W can balance charge & discharge individual cells within a battery pack to ensure uniformity while identifying any faulty cells without requiring disassembly and restore unbalanced battery packs to their normal balanced state through balancing charge-discharge operations.

The device features a modular design, enabling parallel testing with a maximum current capacity of 200A.

The device is widely utilized in battery production facilities, battery recycling plants, research laboratories focusing on batteries development or new energy vehicle batteries testing and maintenance.

Intelligent, multi-functional, one machine to meet different testing needs
Modular Design, Easy Maintenance

The modular design enables flexible combinations, allowing multiple devices to be integrated into a testing cabinet for efficient and rapid completion of testing and maintenance tasks for the entire battery pack.

Isolated channel design, each channel is independently controlled and does not affect each other. After-sales maintenance is simple and convenient. If a single channel fails, just replace the module to complete the repair.

DT50W-160 is composed of the single DT50W-20, a number of DT50W-160 can constitute a testing group to match the needs of mass testing.
