A battery simulator, also known as a battery emulator, is a bidirectional power supply designed to replicate the electrical behavior of a battery. A real battery's voltage and current output fluctuate dynamically based on the connected load and its State of Charge (SOC). A battery simulator accurately reproduces this dynamic behavior without the need for a physical battery.
Testing with actual batteries requires time-consuming charge and discharge cycles to reach a specific SOC. In contrast, a battery simulator enables rapid evaluation by instantly setting any desired SOC, significantly accelerating the development and testing process.
Operating Principle
Most battery simulators function as bidirectional DC power supplies, combining the capabilities of a power supply (source) and an electronic load (sink). This allows them to simulate both battery charging and discharging. Crucially, during discharge simulation (sink mode), Matsusada Precision's systems utilize regenerative technology. Instead of dissipating energy as heat, the system returns absorbed power to the AC line, improving energy efficiency and reducing cooling requirements in the test environment.
I-V Characteristic Simulation
Battery simulation is based on I-V (current-voltage) curves, which define a battery's fundamental electrical characteristics. By programming multiple I-V curves corresponding to different SOC levels, users can achieve highly realistic simulations of battery performance under various conditions.
