Voltage Accuracy


The Chroma 17040E Regenerative Battery Pack Test System is a highly precise and efficient solution for secondary battery module and pack testing. With its energy regenerative function, it reduces power consumption during discharge and ensures a stable power grid without harmonic pollution. The system offers dynamic profile simulation, parallel channels, and advanced safety features. Discover how the Chroma 17040E enhances testing accuracy and flexibility while minimizing waste energy and meeting international test standards.

Bidirectional Circuit for Power Supply Protection

The bidirectional circuit architecture allows highly efficient recycling of the discharge energy. Chroma 17040E accurately controls reverse current changes, the AC current waveforms are smooth and show changes in real time, and the design meets the grid requirements without contaminating other equipment on the grid. When any abnormalities on the power grid are detected, the test system will swiftly cut off the main circuit power supply to protect its safety.

High-frequency Sampling for Battery Pack Capacity Capture

The high-frequency sampling measurement technology reaches a 50kHz sampling rate to ensure dynamic measurement accuracy. Other battery chargers and dischargers use software to read current values for power computing; however, limited data sampling speed could result in large errors when calculating the dynamic current capacity.

Chroma increased the V/I sampling rate and added a double-sampling integrator, so the 17040E test system is able to provide capacity calculation with much higher accuracy. When the current changes, the data is not lost and the transmission speed is not affected.
