5V5A 256 Channel Battery Charge and Discharge Tester for Pouch Cell

SPECIFICATIONS

Product pictures are just as reference , please in kind prevail

1.The Basic composition

This equipment is mainly composed of computer, communication interface and battery testing cabinet. The battery testing cabinet consists of a fixture and a board for placing the fixture, a constant current and voltage source, a hosting control circuit, a sampling circuit, a microcontroller and a control panel.

3.Main feature

（1） Each equipment can do constant current, constant voltage charge and constant current discharge for 256 pcs of cell which is within the voltage range.

（2）Constant current-constant voltage power supply, constant current to constant voltage switching without impact, especially suitable for lithium ion battery charging requirements

（3） The device adopts AVR single-chip computer as the control center, and cooperates with the peripheral sampling circuit, which can be controlled by the upper computer. When connected to the computer, the complete charge and discharge curve of all channels can be saved, or it can be separated from the upper computer and operated by the control panel. Constant current constant voltage charging, constant current discharge test, sorting by time, etc.

（4） Each battery has its own independent constant current and constant voltage source, and the self-forming loop does not affect each other. 

（5）A LED is mounted on each of the battery fixtures as an operational status display, and when the discharge is completed, it can be used to indicate battery capacity sorting. 

（6）Real-time detection each battery voltage, when charging, first constant current charging, when the battery voltage reaches the set value, it will smoothly transfer to constant voltage charging, when the set time or current termination condition is satisfied, the charging ends. When the constant current is discharged, when the battery voltage is lower than the set value, the discharge ends and the corresponding battery indicator lights up. 

（7）With power-down protection function, the original workflow can continue to run after the power back

（8）The upper computer can set 32 working step parameters and 256 cycles. Each upper computer can connect 1 to 15 sets of single chip microcomputer system.(suggest below 10 sets)

（9）Supporting software features

1) . Use the graphical operation interface to display data such as voltage, current, time, and capacity of each battery, and display the corresponding working status and abnormal conditions in various colors.

2) Arbitrary segmented battery capacity indication (up to 100 segments)

3) The data points can be recorded according to the changing conditions of voltage, current and time to form a complete charging and discharging curve data, and the time interval of the curve data points is ≤10 seconds.

4) Battery sorting function under various conditions (capacity, time, open

circuit voltage, discharge platform, etc.)

5) Automatic calculation of constant current charging ratio, capacity loss, discharge efficiency, average voltage, median voltage, etc.

6) Operator permission setting, hierarchical operation

7) Can display charge and discharge curve, cycle diagram

3. Technical parameter
