The usage scenarios of smart active balance BMS :
Electric Vehicles (EVs) and Hybrid Electric Vehicles (HEVs): Smart
active balance BMS is crucial in electric and hybrid vehicles to
monitor, manage, and balance the battery cells. It helps optimize
the performance, extend the battery life, and ensure safe operation
of the vehicle.
Energy Storage Systems (ESS): In applications like home energy
storage or grid-scale energy storage, BMS plays a vital role in
managing the charging and discharging cycles, optimizing energy
utilization, and ensuring the overall health of the battery pack.
Renewable Energy Integration: BMS is used in conjunction with
renewable energy systems, such as solar or wind power, to store
excess energy in batteries. The smart balancing ensures efficient
energy storage and release when needed.
Uninterruptible Power Supply (UPS): BMS is employed in UPS systems
to manage the energy storage component, ensuring a reliable and
stable power supply during electrical outages.
Portable Electronic Devices: In applications like laptops,
smartphones, and other portable electronic devices, smart BMS helps
manage and protect the battery, optimizing charging cycles and
enhancing the overall lifespan.

Precautions:
①. Installing the protection equalization board requires a certain
amount of electronic knowledge.
②. Welding the cable: The first cable (black line) is connected to
the total negative pole of the battery, the second cable (red line)
is connected to the positive pole of the first battery string, and
the third cable (red line) is connected to the positive pole of the
second battery string... and so on, connect all the cables;
③. Detect the cable: After connecting the cable, measure the
voltage between two adjacent cables from the head of the cable to
confirm that there is no problem of wrong connection or missing
connection in the welding sequence of the cable.
④. Connect the B+ line of the protection board to the total
positive pole of the battery, and then connect the sampling cable
plug to the protection board. After activating the protection
board, confirm that the voltage before the board (battery voltage
B+.B-) and the voltage after the board (P+.P-) are consistent.
