This manual provides you with very important installation and operation guidelines, which will guarantee your equipment an optimal performance and longer service life. For your safety, please do not open battery by yourself, only professionals shall be allowed to open and maintain the battery ;...

  • Page 16: Operation Parameters

    Operation Parameters Ambient temperature is -15℃~45℃ and the optimal operation temperature is 25℃±5℃. Ambient humidity less than RH 92% Altitude less than 4500m, if operation altitude more than 4500m, please make special reminder when confirm order. Factors Influencing Capacity Quantity of electricity battery discharge under certain condition is called battery capacity, symbol is C, normal unit is Ampere Hour, and in short is Ah.

    Figure 3-2 service life and temperature curve --- SSP series Figure 3-3 Service life and temperature curve --- SP series Charge Floating charge Charge method: 2.27V/cell with limited current of 0.3 C (A). Charge voltage should be adjusted according to ambient temperature, temperature compensation coefficient is -3mV/cell/℃.

  • Page 18: Battery Calculations

    Cycle application Charge method: 2.45V/cell with limited current of 0.25 C (A). Charge voltage should be adjusted according to ambient temperature, temperature compensation coefficient is -4mV/cell/℃. Setting charge capacity as 105-110% of discharge capacity, when the constant charge current keep as same value for 3hrs, charge end. Fast charge Increasing the charge voltage to 2.40V per cell can reduce recharge time and it is possible, depending on the depth of discharge, to half the recharge time.
  • Page 19 Preliminary calculation:  The maximum number of cells: 490V/2.27V=216 cells;  The minimum voltage per cell at the end of discharge: 378/216=1.75V. Case1: discharge with a surge at the end of discharge The surge power is to be 50kW for 10 minutes, followed by 10kW for 2 hours. Discharge current: During the surge:50000W/378V=132 amps, and then:10000W/378V=26 amps Determining the cell required for the current required:...

  • Page 20: Operating

    Accidental deep discharge This may involve discharge of the battery into indicator lamps, a lower load on the battery than that Initially planned, a failure of the charging system, a discharged battery not recharged immediately, etc… On a fully discharge battery: All of the sulphuric acid has been consumed, and the electrolyte is now nearly water.
  • Page 21 Unpacking the battery  Each shipment is accompanied by a packing list  The packing list should be checked, and the Sales Department should be told immediately of any missing items. Setting up the battery racks The structure should be assembled in accordance with instructions supplied with the equipment.

  • Page 22: Storage

    General recommendations  Do not wear clothing of synthetic material, to avoid the generation of static potentials.  Use insulated tools  Place the cells beginning with the least accessible rows, spacing the cells as shown on the drawing.  Consult the drawing for the correct position of the battery poles (positive=red color, negative=black color).
