4.High-Precision Measurement for 52S/104S Energy Storage Batteries
Industry Challenges: Conventional 500V test systems typically do not support current range segmentation, or segmentation is only effective in constant current(CC) mode. In constant voltage (CV) and constant power (CP) modes, current ranging is ineffective. As energy storage battery capacity calculations under national standards are usually performed in constant power (CP) mode, traditional systems without current ranging result in low charge/discharge capacity accuracy.
Nebula 500V Series Advantages:
- Precisely supports 52S and 104S battery packs: Fully compatible with mainstream commercial and industrial energy storage modules.
- Multi-voltage compatibility: Also supports low-voltage module testing, eliminating the need for additional low-voltage equipment and helping reduce total system costs.
- Accurate constant power testing: Enables intelligent current range switching in constant current, constant voltage, and constant power modes, ensuring high-accuracy capacity measurement in compliance with applicable standards.
5.Flexible Negative/Positive Voltage Switching with Current Boost for High-Dynamic Testing
- The Nebula 500V Series supports flexible switching between negative and positive voltage modes.
- When switching from negative-voltage mode to positive-voltage mode, the system achieves an effective current boost, enabling higher dynamic performance.
This capability supports more cost-effective high-dynamic test applications, delivering greater performance without additional hardware investment.
Industry challenges: Conventional positive-voltage test systems cannot support 0 V or negative-voltage battery testing, requiring additional negative-voltage equipment and resulting in higher system costs.For over-voltage and over-discharge tests, traditional systems typically use a 10 ms sampling interval, which lacks sufficient resolution for capturing critical transient events.
Nebula 500V Advantages:
- Ultra-fast current slew rate to accurately emulate real battery current response under high-dynamic conditions.
- Seamless negative-to-positive voltage switching, delivering higher-quality, continuous test data without interruption.
