  purpose: | To become familiar with battery specification.  |

| 1.  Specify
  a battery system. | Specification
  of auxiliary systems (such as batteries) is similar to that of the renewable
  energy systems covered in the last exercise. To specify an
  auxiliary system choose the Auxiliary tab in the upper-left frame.
  Right-click within the upper-left frame and the select  Details of the  In the Battery System tab find the Number of Series connected batteries and change the number to 200 and then press the Enter key (important) to register the new number of batteries. Input ‘1’ to define Number of Parallel connected batteries. Press the button select system; a profile graph of the characteristic of the battery system will be shown in the bottom frame and an item with the title of single 145@12 will be added to the tree of ‘Battery Storage’ in the upper-left frame as illustrated in the screen shot below. Rename the item as ‘1 x 200’ as instructed in the ‘Specify Supply profiles’ section.  NOTE:  As the performance
  of the auxiliary systems cannot be calculated until the demand/supply
  matching stage, the
  characteristic curve of the battery
  system selected is graphically shown in the bottom window.  The system
  will be included in the matching analysis.  In the same way, register another battery
  system with 4 Parallel connected and 50 Series connected, and
  rename it as ‘4 x 50’. You have now defined two
  battery systems with different specifications.
