A battery simulator, also known as a battery emulator, is a bi-directional power supply that simulates the operation of a battery. A battery's voltage and current output fluctuate based on the connected load and its State of Charge (SOC). A battery simulator is designed to accurately replicate this dynamic behavior. Testing a physical battery requires time-consuming charge and discharge cycles to reach a specific SOC. In contrast, a battery simulator enables rapid evaluation across various conditions by instantly setting any desired SOC.
Most battery simulators are bi-directional power supplies that combine a DC power supply with an electronic load to simulate both charging and discharging. In addition, when simulating battery discharge (sink mode), the regenerative function returns the absorbed power to the AC line, significantly improving energy efficiency.
Battery simulation is based on I-V (current-voltage) curves, which represent a battery's fundamental electrical characteristics. Furthermore, by defining multiple I-V curves for different States of Charge (SOC), it is possible to achieve a highly realistic simulation of the battery's behavior.
Battery simulator function
Matsusada Precision's battery simulators can readily simulate a battery's I-V characteristic curve. Additionally, the voltage/current can be set at up to 1001 points within the rated values, enabling a more precise characteristic simulation.
Matsusada Precision manufactures regenerative DC power supplies, PBR, and PBRM series, which can simulate a high-power battery. This regenerative DC power supply (bi-directional power supply) with a large touch panel display is energy-saving, compact, and high-power, as its ability to regenerate power to the AC line during discharge simulation (sink mode) reduces overall energy consumption and heat dissipation.
