256 Channel 5V 30A Lithium Cylindrical Cell Grading Machine with Horizontal Tray and Energy Regenative Function

I. Equipment Configuration List

II. Equipment Scope and Function

l Scope of application: Mainly used for cell grading, suitable for specific types of cells (cylindrical 32-40).

l Supported tests: Constant current charge, constant current-constant voltage charge, constant current discharge, rest, etc.

l Energy feedback:

Adopting energy-saving voltage reducing chip DC to DC (14V-5V) conversion method to improve conversion efficiency and synchronize

Rectification technology, with an output efficiency of 90%, can reduce workshop temperature.

The discharge adopts DC-DC, and the battery voltage is converted into DC 15V through a boost circuit during battery discharge,

Then DC (15V) - AC (220V) is connected to the grid, generating a large amount of heat through traditional battery discharge

Measure the amount of electricity recovered from DC-AC batteries while improving the temperature environment in the workshop.
