512 Channel 5V 6A Polymer Battery Charge Discharge Tester Pouch Cell Capacity Life Cycle Tester
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.
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.
