A battery simulator, also known as a battery emulator, is a bi-directional power supply that simulates the operation of a battery. The voltage and current output of a battery vary depending on the load connected to it (power consumption) and its remaining capacity (State Of Charge, SOC). A battery simulator simulates this. If you want to test a real battery, you have to wait for it to reach the required SOC by charging and discharging it. With a battery simulator, you can quickly perform various tests by simply changing the settings.

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 the charging mode (electronic load mode), the regenerative power supply with a battery simulator function is used to return the power consumption to the AC line.

The battery simulation operates based on the I-V curve characteristics, which are the basic characteristics of a battery. Furthermore, by setting the I-V curve characteristics according to the remaining capacity (SOC) % of the battery, it is possible to simulate a more realistic battery operation.

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 because it can regenerate power to the AC line during charging mode.
