Enerkey 2S-16S 2A Smart Active Balancer Balancing Accuracy 1MV 12V 24V 36V 48V 72V 92V 112V Lifepo4 and Li-ion Battery Balance Board For Electric Car and Scooter
Electric vehicles generally use lithium-ion power batteries, whose single cell capacity and voltage vary greatly, which are prone to inconsistency during charging and discharging,
resulting in a shortened driving range of electric vehicles and affecting the battery life. Currently, the commonly used power battery for electric vehicles is lithium iron phosphate battery.
Since lithium iron phosphate battery is a secondary battery, inconsistency will occur during the charging and discharging process, which is due to the different internal resistance and resistivity of lithium iron phosphate battery.
In order to solve this problem, it is necessary to balance the single cell to minimize the internal inconsistency.
Active balancing technology charges or discharges single cells to make the voltage difference of each single cell reach the set value or keep it within a certain range to maximize the performance of lithium-ion power batteries.
The most commonly used active balancing technology is the series-parallel technology.
In a series circuit, each single cell works alone, but when the lithium-ion power battery is fully charged, the single battery pack will remain in a stable state,
which is the so-called "rest period". During this period, the voltage in the battery pack does not change and remains constant.

Wiring Diagram
EK-16S2EB supports cascading use, and at least one battery between every two equalizers is the "common end of energy exchange". The following uses the 32S as an example to describe how to install and connect cables:
Notice:
1.When used in cascade, there is at least one "energy exchange commonend" between every two equalizers. When welding, please note whetherthe connection here is correct.
2.During cascading use, please check whether the wiring is wrongrepeatedly.lf it cannot be used after connection, please contactafter-sales personnel to consult the corresponding cascade diagram.
