Battery Emulation Test SystemRPS
RPS is a Battery Emulation Test System available in eight configurations, covering a power range from 100 kW to 400 kW.
It provides high-precision voltage and current control, fast current response, and seamless power supply for both motoring and regeneration—enabling accurate battery emulation for inverter, motor, and eAxle evaluation tests.
The system supports testing under emulated real-world driving conditions, with control modes such as CC, CV, and CP, as well as a variable internal resistance function.
It also includes essential protections against overvoltage, overcurrent, and overheating to safeguard the DUT and ensure operator safety.
Additionally, optional features allow setting I-V characteristics based on SoC and configuring equivalent circuits for secondary batteries, meeting various customer requirements.

Extending driving range and delivering an exciting driving experience requires inverters with superior power conversion efficiency
and fast response.
To support this development, advanced test environments—such as the one shown below—have been introduced to accurately emulate real-world driving conditions.
These evaluations focus on bidirectional power supply efficiency between the battery and motor, conversion quality factors such as phase shift and noise, and overall response performance.
Because high-current conditions are involved, ensuring operator safety and protecting the DUT are critical.

Extending driving range and delivering an exciting driving experience requires motors that efficiently convert power supplied by the inverter into driving force.
To support this development, advanced test environments —such as the one shown below—capable of emulating real-world driving conditions have been introduced.
In these environments, evaluations focus on key performance factors such as rotational speed, torque, and heat under high-speed inverter control.
Because these tests involve high-current conditions, protecting the DUT and ensuring operator safety are essential considerations.
We provide high-precision Battery Emulators that support multiple test modes (CV, CC, CP) and incorporate a wide range of safety features, enabling a highly realistic reproduction of actual vehicle behavior.
