HSTP3T 60-500 KE User Manual
battery is 40, it means that there are 40 blocks of batteries and both the positive
and negative are 20 blocks of batteries.
In the case of cell battery of 2V (usually with large capacity) is used, battery
number should be the same as the block battery. The cell battery actually in use
should be 240 cells (6*40), with both and positive and negative of 120 cells.
The battery number setting range is 36-44
2) Setting battery number for LFPB
For the cell of each LFPB, the cell voltage is 3.2V; each battery block consists of
1 cell. In total, if 40 blocks of Lead- Acid battery are used, for the LFPB, the
number will be 150. Both the positive and negative are 75 cells.
The battery number setting range is 140-180.The lowest EOD voltage for the
LFPB will be 360V and highest voltage can be 620V.
5.4.3 Battery Capacity Setting
Battery Capacity Setting sets the capacity value of the battery block .For example,
if the system uses 40 blocks of 12V/100AH batteries, the Battery Capacity Setting
should set to 100 Ah. If 240 cells of 2V/1000AH are used, the Battery Capacity Setting
should be set to 1000 Ah.
In case of there are more than one strings of battery in parallel, the battery
capacity setting value will be the times of the single string. For instance, if the
configuration is two strings of 40 blocks of 12V/100AH batteries, the battery capacity
setting should be set to 200AH.
The system sets current limits according to the battery capacity set. For the
Lead-Acid battery, the current limit is 0.2C, and for the LFPB, the current is 0.3C. For
instance, the 500kVA is configured to 40 blocks of 12V/500AH batteries, which can
provides total max charging current of 160A.Due to the current limits(0.2C) , the max
charging current will be 100A(0.2*500A).
5.4.4 Float and Boost Charge Setting
In boost charging, the system charges the batteries with constant current. After the
period, the system will enter the float charging.
For the Lead-Acid battery ,the default float charge voltage per cell is 2.25V, boost
charge voltage is 2.35V
；
For the LFPB, the default float and boost charge voltage per cell is 3.45V
5.4.5 OD Voltage Setting
The EOD voltage 0.6C is the EOD voltage when the discharging current is larger than
0.6C;
EOD voltage 0.15C is the EOD voltage when the discharging current is less than
0.15C.EOD voltage decreases linearly as the EOD voltage Current increases from
0.15C and 0.6C, as shown in Fig.5-3.
