Information about software:
The user selects a battery type and enters data for any D.C. to D.C. converters and power switches. Then, after entering a current drain profile for the product, a simulation run starts by 'pressing' either theCapacity or Run Time command button. During the ensuing simulation, the battery voltage gets plotted in the oscilloscope area with remaining battery capacity or running time for the X axis. The simulation also reports numeric data in the Simulation Summary area. All data entry forms, including simulation plots, can be printed by the user by 'pressing' the print button.
Simulation cannot give precise figures for the battery discharge time (life) of a complex product. Few users would care to model the current drain with the accuracy required for this precision. However, all models incorporated within the program maintain sufficient realism to give a very accurate interpretation of differences between simulation runs.
The inherent repeatability of the simulation environment provides the precision needed to quantify changes to the power management system. Such changes can be simulations with different battery capacities, changed converter efficiencies and, alternative current drain profiles.
Simulation also helps to quantify cost versus performance tradeoffs for the power system. Simulations with different numbers of battery cells, circuit components or power management strategies provide very accurate answers to help in making needed decisions.
