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 upporting 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.
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.
