What Is the High-Voltage DC Battery Pack Cycler and Emulator?

The NI High-Voltage DC Battery Pack Cycler and Emulator is used as a battery cycler, regenerative, bidirectional DC source, regenerative DC load, high-power DC source, and/or battery DC emulator.

High Voltage DC Cycler and Emulator System Benefits

Save Energy

Regenerative capability with more than 90 percent power recovery leads to significant electrical cost savings.

Scale as Needed

The modular design allows easy field expansion up to 2.4 MW and 8,000 A, ensuring adaptability as testing needs grow.

Test with Versatile Ranges

Dual voltage ranges (1,200 V/167 A and 600 V/333 A at 100 kW) cater to a wide range of testing requirements and fast voltage, current, and mode transition times.

Simulate Realistically

The system safely emulates real-world conditions, including fast transitions, over/undercharged batteries, BMS failures, and more, while standardization lowers the cost of service across applications.
