512 Channel Battery Tester for Battery Charge and Discharge Testing Lithium Ion Battery Experiment

 


This equipment mainly constitute by the computer system and control software, communication interface and battery detecting cabinet. Battery detecting cabinet comprises a fixture and placed the plate body of the fixture, charging, constant current and constant voltage source discharge constant current source, storage control circuit, current sampling circuit, voltage sampling circuit, the main control CPU, data memory, microcontroller programming and control panel.

 

Features

1. It is pecially used for chemical and capacity separation of polymer lithium ion batteries.

2. Per device consists of a set of completely independent MCU control system, using double-sided structure for our customers to save plant area, the whole equipment can test constant current charging and constant voltage of 512 monomer lithium ion battery;

3. The tester uses an unique constant current constant voltage power, constant current to constant voltage switch without impact, especially suitable for lithium ion battery charging and discharging requirements;

4. The device can control center by using P89C668 single chip computer, device can control by upper computer or break away it with the external sampling circuit to complete constant current constant voltage charging, constant current discharge test, capacity sorting work.

5. Each battery test station has independent constant current and constant voltage power.
