Product Description

 

Product Description

Monitoring: The BMS monitors the state of the entire battery cells on a cell-by-cell basis.
Voltage measurement:
The BMS measures the voltage of each battery cell or the overall voltage of the battery pack, thereby preventing an overcharging or excessive discharging.

Current measurement:
The BMS measures the discharge current from the battery or the charge current to the battery. It checks the use status or the charged state of the battery and performs proper control.

Temperature measurement:
The BMS constantly monitors the temperature of the battery through a temperature sensor. Using the battery within a proper temperature range ensures the safety of the battery and longer service life.

Control:The BMS eliminates variations in performance of individual battery cells to allow them to work uniformly.
A large-capacity battery pack consists of a number of battery cells. These cells vary in performance, and deteriorate at different rates. For example, when a specific cell deteriorates faster than other cells do,

it may affect the overall performance or service life of the battery pack. Such variations in performance or deterioration rate are eliminated by a function called "balancing."

Wiring precautions:
1. Installing the protective board requires a certain amount of technical electronic knowledge.
2. When wiring, first connect the B- wire at the soldering pad position to the total negative terminal of the battery (the B- wire should be soldered to a short and thick wire) and solder the wired terminal to the battery pack first, and then insert the protective plate.
3. The connection between the battery terminal B- and the protection board terminal B- should be short and thick, otherwise it will cause the protection board to charge and discharge in advance and malfunction.

4. You need to use thick wires when wiring P+/P-. Wires that are too thin and too long will burn the board!
