             BAL-5624 Lithium Battery Pack Unit Voltage Equalization Controller

Features and advantages

• Max equalized current up to 5A.
• Automatically analyze the maximum voltage difference value and average voltage value of the battery pack, and quickly understand the voltage of each string of the battery pack during equalizing.
• Nano amorphous isolated fully symmetrical transformer ensures the minimum voltage difference.
• American ultra-low internal resistance MOS devices form an ultra-low dynamic impedance inverter circuit,which can achieve high power.

Why do battery pack need to be balanced?

1.The battery pack has been charged and discharged many times, the electrolyte inside the battery is depleted and the activity of the internal chemical substances is reduced.The internal resistance of the battery will increase to varying degrees.

2.The greater the difference in internal resistance, the greater the voltage difference between the batteries in the battery pack will be if used for a long time. This will shorten the charging time and prevent the battery from being fully charged, it will affect the mileage and lifespan.

3.If the voltage difference is greater than 0.5V will be power failure at start-up, short charging and use time, so battery equalizer is used to balance it.

Which situation need to use balance board for battery pack balance?

The electric bike lose power from starts up and charging and use time are short. First, the voltage of battery pack’s each series need to be checked. The equalizer could be used to balance if the difference of voltage is over than 0.3V. Second, the resistance of battery pack also be checked. The bigger difference of internal resistance is, the bigger difference of voltage. The big resistance of battery use electricity more. This situation is easy to disconnect power source.

Which situation does not need to use equalizer for battery pack balance?

1.It is long time not to start electric bike. The battery pack is in insufficient voltage. in this situation, the battery pack cannot be activated or restored by balance device and need to be used the specific charging machine to activate.

2.If the battery damage,there is no voltage, the corresponding battery should be replaced in a timely manner before voltage balance repair. 

Equalizer repairable battery:The battery is normal charging & discharging. There is no damage battery or insufficient voltage. The voltage of each series battery is the same. The balancer cannot repair the damaged battery.
