512 Channels 5V 6A BFGS Pouch Cell Capacity Grading Tester

512 Channels 5V 6A BFGS Pouch Cell Capacity Grading Tester

Introduction

This equipment is mainly composed of a computer, a communication interface and a battery detection cabinet. The battery testing cabinet is composed of a board including fixtures and fixtures, a constant current and constant voltage source, a register control circuit, a sampling circuit, a single-chip microcomputer and a control panel.

Features

1. Each device can perform constant current and constant voltage charging and constant current discharge tests on 512 batteries that meet the voltage range.

2. The invention patented constant current-constant voltage power supply is adopted, and the switch from constant current to constant voltage has no impact, which is especially suitable for the charging requirements of lithium-ion batteries.

3. The equipment adopts AVR single-chip computer as the control center, and with the peripheral sampling circuit, it can be controlled by the upper-level computer. When it is connected to the computer, it can save the complete charge and discharge curves of all channels, or it can be separated from the upper-level computer and operated through the control panel. Constant current and constant voltage charging, constant current discharge test, sorting by time, etc.

4. Each battery completely has an independent constant current and constant voltage source, which is self-contained and does not affect each other.

5. The voltage of each battery is detected in real time. When charging, it is first charged with constant current. When the battery voltage reaches the set value, it will smoothly switch to constant voltage charging. When the set time or current termination condition is met, the charging ends. In constant current discharge, when the battery voltage is lower than the set value, the discharge ends and the corresponding battery indicator lights up.

6. With power failure protection function, it can continue to run after the original work flow is connected.

7. The power tube adopts 50N06, which is suitable for batteries that require lower discharge voltage, such as lithium iron phosphate batteries.

8. The upper computer can set 32 step parameters and 256 cycles, and each upper computer can be connected to 1-10 sets of single-chip computer systems (10 sets or less are recommended).

9. Supporting software functions.

a) Graphical operation interface is used to display the voltage, current, time, capacity and other data of each battery, and the corresponding working status and abnormal conditions are displayed in various colors;

b) Any segment battery capacity indication (up to 100 segments);

c) Data points can be recorded according to the changing conditions of voltage, current and time to form a complete charging and discharging curve data. The time interval of the curve data points is less than 4 seconds

d) Various conditions (capacity, time, open circuit voltage, discharge platform, etc.) for battery sorting function;

e) Automatic calculation of constant current charging ratio, capacity loss, discharge efficiency, average voltage, median voltage and other data;

f) Operator authority setting, hierarchical operation;

g) It can display charge and discharge curve diagram and cycle diagram;
