8/16/32/64 Channel Prismatic Battery Testing Machine Cell Grading Machine

1. System  features:

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

The accuracy of the equipment is 0.05% and the stability is high.            

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

Four wire test interface to ensure high measurement accuracy.       

Modular design concept, easy to maintain.

The equipment structure is mainly composed of the following parts:

1、Independent   CPU   board   and   supporting   keyboard   board,  front  and  rear double-sided independent operation,  and  the  whole  cabinet  sends  control  uniformly ;

2、4-channel  constant  current  and  constant  voltage  control  module ;

3、Bidirectional AC/DC inverter module.

4、Flat head clamp, electric automatic unclamping. Compatible crocodile clip.

2. System  composition:

1.  Lithium  battery  into  capacity  sharing  equipment.

2.  Computer  with  USB  interface  (self  provided).

3、USB  to 485 interface converter and conmmunication line.

4、Battery  scanning  system

5、Software.

3. System principle:

The equipment is connected and controlled by computer, sending instructions and collecting data; The keyboard can manually operate the equipment and display parameters and status; Under the command of CPU, the constant current board has the function of constant current and constant voltage; When the battery is charged, the two-way power supply converts the AC into 12V DC, and the charging control and detection of the battery are realized through the constant current board; When the battery is discharged, the process is opposite to charging. Firstly, the battery voltage is increased to 12V through the constant current board, and then the DC is transformed into AC through the two-way power supply, which is directly fed into the AC distribution network of the factory, so as to realize the energy feedback of battery discharge electric energy.

Remarkable power saving effect: according to the actual measurement, the power consumption of the equipment during charging is more than 40% lower than that of traditional equipment, the comprehensive power saving rate is more than 60%, and the power consumption is more than 60%, which saves a lot of costs for battery manufacturers
