Battery Testing Machine 18650 21700 26650 Cylindrical Battery
Capacity Dividing Classify Equipment Cell Grading Cabinet
The grading machine is divided into different types: cylinder,
aluminum shell and polymer. The internal structure of them is
exactly the same, but the clamps are different. The cylinder and
the aluminum shell use upper and lower needles to contact, while
the polymer uses a gold-plated flat clamp to clamp the tabs for
punching. Different channels can be customized according to
customer requirements, and the current and voltage are unified, its
suitable for mass production.
Cell Grading Machine Features
1. Detect the voltage of each battery in real time. When charging,
charge with constant current first. When the battery voltage
reaches the set value, it will smoothly switch to constant voltage
charging. When the set time or current termination conditions are
met, the charging is finished. In constant current discharge, when
the battery voltage is lower than the set value, the discharge will
end and the corresponding battery indicator light will be on.
2. It has the function of power-off protection, and can continue to
run after receiving the original work flow.
3. The power tube is 50N06, which is suitable for batteries with
lower discharge voltage, such as lithium iron phosphate battery.
4. The upper computer can set 32 working step parameters and 256
cycles, and each upper computer can be connected with 1-10 sets of
single-chip microcomputer system (less than 5 sets are
recommended).
