what is high voltage battery system?
1.For the lithium iron phosphate battery cells, the single cell voltage is always 3.2V, all voltage, current, power (kW) and energy(kwh) applications are based on this.
2.High voltage lithium battery system usually refers to the battery system voltage is greater than or equal to 96V, for example,192V 50Ah battery system is 1P60S (60 cells series connected) cell connection based on 50Ah single cell.
3.For high voltage, in the single-cluster battery system, the batteries are always connected in series to achieve a higher voltage.Moreover,there is a high voltage DC main unit is needed to manage this high voltage cluster.
4.The main function of the high voltage DC main unit is to manage all the BMU units of this cluster through the master BMS, meanwhile to provide start-stop, protection and other functions for this cluster
ding functional control.
