SI BAL-8624 – Lithium Battery Pack Voltage Equalization Controller

Description

Overview

Semco SI BAL-8624 equalizer controller adopts- high frequency transformer inversion and equipotential isolation coupling energy technology to realize the parallel connection of each series of batteries through equipotential isolation coupling. Based on the parallel connection state, each series of batteries with different high and low voltage realize energy transmission and distribution, and finally realize the high efficiency and precise balance of the battery pack. The Taiwan main control chip MCU combines with the ultra-low dynamic impedance inverter to obtain the more than 5A/8A balanced current. The precise transformer process and fully symmetrical circuit design can achieve the balanced effect of < 30mV.

Features of Machine:

1. Automatically analyzing the maximum voltage difference value and the average voltage value of battery pack. When balancing, it can quickly detect the voltage of each string of the battery pack.
2. Voltage difference analysis and equalizing voltage dual function.
3. Equipped with multi-mode intelligent voltage detection display, it can monitor the working progress of battery pack repair in real time.
4. Nano amorphous isolated fully symmetrical transformer ensures the minimum voltage difference.
5. American ultra-low internal resistance MOS devices constitute an ultra- low dynamic impedance inverter circuit. Achieve high power balance.
6. The control and management of intelligent MCU chip realize automatic self-balancing.
7. Automatically detect the minimum voltage of the battery, stop working when the battery energy is low, and protect the battery from power loss.
8. Overcurrent fuse resistance at each series input end to ensure safety.
9. 1H/3H/4H time-limited equalization time adjustable.
10. Heat dissipation design of inverter under extreme equilibrium state of high voltage difference.

About the voltage difference between battery strings after equalization:
1. The min voltage difference of 24 series design is S30mV (actually15-20mv); 2.The min voltage difference after equalization is related to the equalization time.
2. The longer the equalization time is, the smaller the pressure difference is;
3. The minimum voltage difference after equalization is related to the battery internal resistance, connecting line resistance and connector resistance.
