With the fast growing demand for electrical storage systems not only triggered by the solar energy boom but also by e-mobility, the need for simulation of battery systems has become highly prominent. Battery Simulators allow the engineer to do his R+D work and various tests repeatably, energy-conscious and much faster than by using real battery stacks. Even extreme situations as for example operation under arctic temperatures or with high cyclic rates may be played through easily by a suitable software.
REGATRON Battery Simulators are made up of a bidirectional REGATRON DC power supply equipped with the powerful Application Software BatSim. This software is resident on-board the DC power supply respective on-board the master unit of a bigger system and is handled by a PC shell software. The fast BatSim process is running in real-time perfectly matched to the internal timing of the DC power supply. By this, an optimum computing rate can be reached leading to a nearly one-to-one time behaviour even in the case of steep changes in charge/discharge current.

Optional hardware for Reverse Polarity Protection. Prevents switch-on of the DC power supply if an external battery is being connected with wrong polarity.
Furthermore, if a battery is connected to the DC power supply, RPP starts a “pre-charge sequence” in order to bring the power supply to the same voltage as the battery. This prevents very high inrush currents from flowing from the battery back to the power supply output stage.
