5V 3A 6A 18650 21700 26650 32700 Lithium Ion Cell Capacity Grading Machine


Product Description

ACEY-BCT506R-512H lithium ion battery testing machine is used for cyclic charging and discharging capacity testing of cylindrical batteries with a diameter range of 18 to 32 mm. It comes with a tray that can be turned over and used for different sizes of batteries. The whole machine has 512 channels and can test 512 cells simultaneously. And there are energy feedback and linear versions available for selection.


System Features

1.Single point independence, each battery has an independent constant current and constant voltage source, stable and without impact.

2.The accuracy of the equipment is 0.1% and the stability is high.

3.The software has powerful functions and friendly man-machine interface.

4.The four-wire test interface ensures high measurement accuracy.

5. Modular design concept, easy to maintain.


Equipment Structure

1. Independent CPU board, double keyboard board, independent operation of front and back sides, unified transmission control of the whole cabinet;

2. 8-channel constant current and constant voltage control module.

3. Two-way AC/DC inverter module.

4. Flat-head clamps, tray type manual opening clamps.


System Principle

1.The equipment is controlled by a computer connection, sending instructions and collecting data, etc.; the keyboard can manually operate the equipment, displaying parameters and Status; the constant current board is instructed by the CPU and has constant current and constant voltage functions; when the battery is charged, the bidirectional power supply converts the alternating current into 12V direct current, and the constant current board realizes the charging control and detection of the battery; when the battery is discharged, its process Contrary to charging, the battery voltage is raised to 12V through the constant current board, and then the DC power is converted into AC power through the bidirectional power supply and fed directly to the AC power distribution network of the factory, thus realizing the energy feedback of the battery discharged electric energy.

2.Significant power-saving effect: According to actual measurement, the power consumption of the device during charging is reduced by more than 40% compared with the power consumption of traditional devices. The comprehensive power-saving rate is more than 60%, and the power consumption is more than 60%, which saves a lot of cost for battery manufacturers.
