512 Channel 5V 3A Battery Grading Machine For Cylindrical Cell Testing

1. Basic Composition of Equipment

The equipment is mainly composed of computer, communication interface and battery detection cabinet. The battery detection cabinet is composed of a clamp and a board body for placing the clamp, a constant current and constant voltage source, a storage control circuit, a sampling circuit, a single chip microcomputer and a control panel.

2. Main Performance of Equipment

1) Each equipment can conduct constant current and constant voltage charging and constant current discharge tests on 512 batteries that meet the voltage range.

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

3) The equipment adopts AVR single chip computer as the control center and cooperates with the peripheral sampling circuit. It can not only be controlled by the superior computer. When the computer is connected to work, it can save the complete charge discharge curve of all channels, but also be separated from the superior computer and operated through the control panel to complete constant current and constant voltage charging, constant current discharge test, sorting according to time, etc.
