○ Visual & Interface
○ Pack over voltage parameters
○ Pack low voltage parameters
○ Cell high/low temperature(charging) parameters
○ The difference between active and passive balancing
▇ Passive balancing
The battery with higher voltage is discharged by means of resistance discharge, releasing electricity in the form of heat. The advantages are low cost and simple circuit design; the disadvantages are that the balancing is based on the lowest battery residual amount, which cannot increase the capacity of the battery with less residual amount, and 100% of the balancing electricity is wasted in the form of heat. If the balancing current is small, the efficiency of the electricity balancing effect in a large-capacity battery pack with large electricity differences is very low, and it takes a long time to achieve balance, which feels like scratching an itch in the application.
▇ Active balancing
Balancing is done by transferring electricity, which is highly efficient and has low losses. Regardless of whether the battery is charging, discharging, or static, as long as the voltage difference is greater than the set value, balancing will begin. Therefore, as long as there is a voltage difference, active balancing should be done 24 hours a day until the voltage difference is less than the set range. Since active balancing is not limited by charging time, the balancing time is longer and the balancing current is larger, so it is more suitable for use in large-capacity battery packs.
○ Active balance boar - Installation method
○ Cable Assembly
○ Safety precautions
Do not place the battery on flammable building materials.
Recommended to place the battery in the cabinet .
The temperature should be between 10℃and 30 ℃ to maintain the best operating state .
The installation site should be some free space around the battery to dissipate heat
(as shown in the figure below), which is suitable for installation on the concrete surface or other non-flammable surfaces.
○Unboxing steps
1) Open carton
2) Take out the pearl cotton
3) Unfold carton
4) Stand out product,extension rod
