3S 4S 6S 7S 8S 12S 13S 14S 15S 16S 5A LTO Li-Ion Lifepo4 Active Balancer BMS Board For Portable Emergency Power Supply
Product Description
Lithium-ion batteries have been widely used in new energy vehicles
(NEV) as large energy
storage systems (EES). Balancing among series-connected cells is
necessary to avoid overcharging or over-discharging as well as
improve the amount of usable energy. Different from
passive balancing, active balancing redistributes charges among
cells or control cell output
powers, further improving battery efficiencies.
A new active balancing topology and its control algorithms are
finally proposed by Enerkey,One supercapacitor is used in the
balancing circuit which replaces the highest state of
charge (SOC) cell and is charged during the vehicle regeneration
process. The supercapacitor also transfers energy to the lowest SOC
cell after it is fully charged. This new balancing
strategy can not only improve balancing efficiency due to fewer
times of energy conversion
but also reduce balancing time compared to the single capacitor
balancing.

Packing List
Wire connect
NOTE:As shown in the figure above,there can be multiple common ends of energy exchangeso that the efficiency of equilibrium will be higher;It is also possible to use only one common end of theenergy exchange atthejunction of two modules.The other free feet are suspended, and it is best todistribute the number of strings equally on each board.If you need the cascade diagram for more strings, Please contact our online service, Thanks.
