System simulation of autonomous power supplies for determination of battery operating conditions

To calculate the lifetime of a battery it is necessary to know the operating conditions in detail. Based on an existing concept for a system simulation software for autonomous power supply systems Fraunhofer ISE extended the programme in a way that different system designs can be handled with the programme instead of only very few pre-defined system designs. It is now possible to simulate AC or DC coupled batteries and it is possible to simulate various batteries in a system.

The outcome of the programme are time series of battery current and temperature over a period of 20 years taking into account the meteorological conditions and the system design including energy management systems and battery charging conditions. The operation condition will change according to the system design and operating strategies. Therefore the impact of any change in the system design or the operation strategy can be quantified in terms of battery lifetime.

A direct link between the system simulation software and the battery simulation model will be established.
