19 October 2015 Manufacturer independent Battery Sizing according to IEEE Short description and important features

2 AbacusIEEE: History Abacus IEEE has several ancestors, stemming from the late 1990 years Samba Curves 1997 Blanca IEEE Sizing 1998 Ibis IEEE Sizing 2002 One Battery Manufacturer only Strict IEEE 485 Calculation (Lead-acid) Strict IEEE 1155 Calculation (NiCd) Electrically Smallest Solution only Limited Export and Interoperability These versions share several characteristic properties Samba, Blanca and Ibis used by many battery customers worldwide Users known to us include BENNING (Germany), E-ON (Germany), GUTOR (Switzerland)

3 AbacusIEEE: Evolution Abacus IEEE has evolved to a techno and commercial tool during the last decade Unlimited number of Manufacturers There are several editions, both manufacturer dependent and independent Abacus IEEE implements many extensions and has many new features New Users (partly early test stage) include AEGPS, AMETEK, NORTHSTAR, YUASA BENNING Edition 2008 FAAM Edition 2010 FIAMM Edition 2011 HBL Edition 2011 PANASONIC Edition 2012 Calculation Extensions to IEEE 485 and 1115 All possibly usable Batteries calculated Output Documents both technical and commercial Compare Results for different Manufacturers Output Documents in arbitrary languages Link to Rack and Cabinet sizing software Output Documents exportable as HTML, PDF, DOC,

4 AbacusIEEE: Editions Abacus IEEE is available in two main editions Unlimited number of Manufacturers Single Edition is for Battery Manufacturers and their Clients Premium Edition is for OEMs and Battery Traders Abacus IEEE Single Edition est. 1998/2010 Usually Open Redistribute License Find all Results for Distribute Manufacturer Files and Exports interchangeable Cheap Upgrade from Single to Premium is possible One Battery Manufacturer only Usually Open Company License Compare Results for different Manufacturers Abacus IEEE Premium Edition est. 2008/2014

5 AbacusIEEE: Distributions Abacus IEEE is available in two main distributions Running on the PiSoftware Server abacus 5 is for big companies with very many users and needs installation abacus4u is for smaller companies with fewer users and needs no installation abacus 5 Setup Edition est Company-wide License required Updates for Software and Databases needed Files and Exports interchangeable abacus 5 Single Edition can be individually updated to abacus4u Premium Edition Installed on every User‘s Computer Cheap individual Subscription model Software and Databases always up-to-date abacus4u Online Edition est. 2008/2014

6 AbacusIEEE: User Interface design Office Ribbons instead of Menus Language selection Presentation of results very variable Font, font size and font style Database tools Multiple Documents simultaneously

7 AbacusIEEE: Sizing Wizard, Battery Permanent instruction Clear orientation Filter for Battery type Elektrode type Life time Ventilation Application Select database (e.g. manufacturer) Additional settings Select one or more battery types

8 AbacusIEEE: Sizing Wizard, Cells Minimum system voltage leads to Final voltage per cell IEEE-Mode: ONE number of cells Maximum system voltage leads to IEEE-ideal number of cells

9 AbacusIEEE: Sizing Wizard, Cells Minimum system voltage or Final voltage per cell given Cell-Mode: Cells range given Number of cells variegated automatically Final voltage per cell or minimum system voltage will be calculated

10 AbacusIEEE: Sizing Wizard, Cells Minimum system voltage or Final voltage per cell given Voltage-Mode: Voltages given Number of cells variegated. Final voltage per cell or minimum system voltage will be calculated Maximum system voltage and minimum number of cells given

11 AbacusIEEE: Sizing Wizard, Load Comfortable Load input in table IEEE Load types Load profile sortable IEEE Random Load Power loads with KtP und RtP Input with power factor, efficicieny and apparent power

12 AbacusIEEE: Sizing Wizard, Custom Ambient temperatures Custom sizing: Tolerance and State of Charge Mix blocks with various cell numbers Additional parameters: Aging and Design Custom sizing: Range of Parallel strings

13 AbacusIEEE: Sizing Wizard, Project Project data Additional data

14 AbacusIEEE: IEEE Worksheet (HTML) Project data Recommended Battery Load profile Normed calculation Random Load Header

15 AbacusIEEE: Report (HTML) Graphical load profile Recommended Battery Additional data Battery picture Header

16 AbacusIEEE: Calculation control Progress indicator Cancel button Calculations Failures, i.e. unsuitable batteries Success, i.e. usable batteries Progress Remaining time Configurable summary

17 AbacusIEEE: Result list Sorting, e.g. Price or Workload Selection of preferred result Results freely groupable Sorting within groups Multiple grouping Columns, hideable Synchronizing with CellView

18 AbacusIEEE: CellView Additional freely configurable View of all Cellytypes for all manufacturers/databases Sortable, groupable, exportable Synchronizing with ResultList

19 AbacusIEEE: Exporting Result Data for own further processing ABACUS result as HTML, PDF and MS Word File Grouped and sorted result list for further work, e.g. in calculation worksheet Grouped and sorted CellView list for further analysis, e.g. in calculation worksheet Launch Rack & Cabinet sizing software Export to custom database

20 AbacusIEEE: Filtering Top Filter to hide uninteresting results Show best Ten, best 100 or All results Show all suitable Batteries and include their commercial data Show smallest suitable Battery for every Plate type and include Price Show all suitable Batteries but hide their commercial data Show smallest suitable Battery for every Plate type and hide Price Show only cheapest suitable Battery for every Plate type Show smallest suitable Battery for every Plate type and include all bigger Batteries which are not more expensive…

21 AbacusIEEE: Quick Sizing ONE input dialogue for all typical input parameters Preselection of manufacturers and battery types Battery filter System voltages Load Type and Calculation mode Load profile
