1.Overview
Nebula is pleased to announce a functional upgrade to its 2026 Cell Cycle Test System series, enabling integrated ripple superposition during cycle testing.
With this upgrade, the system supports ripple superposition from 1 Hz to 100 Hz, allowing ripple signals to be injected directly into standard charge or discharge test processes. This integrated approach eliminates the need for additional ripple generators, enabling users to perform composite testing within a single system. As a result, equipment investment is reduced while test efficiency and accuracy are significantly improved.
2.Why Integrated Ripple Superposition Matters in Battery Testing?
In real application environments, battery cells are frequently exposed to ripple interference originating from external equipment and power systems. In fields such as electric vehicles (EVs), energy storage systems (ESS), and consumer electronics, low-frequency ripple signals may directly act on battery cells, potentially leading to:
- Abnormal voltage fluctuations
- Increased thermal stress and localized heating
- Accelerated electrode material aging
- Reduced system safety, long-term stability, and cycle life
Conventional test methods usually perform cycle testing and ripple testing separately, requiring multiple systems and making it difficult to reproduce realistic operating conditions. This separation often results in incomplete or less representative evaluation outcomes.
3. Key Features
3.1 Integrated Ripple Superposition Testing
The upgraded Nebula 2026 Cell Cycle Test System addresses this industry challenge by introducing a high-precision ripple simulation module. Engineers can insert ripple simulation steps independently and seamlessly into existing test profiles, including constant current (CC), constant voltage (CV), and dynamic cycling modes.
This allows ripple signals with predefined frequency and amplitude to be injected while the cell is charging or discharging, creating a composite test environment that closely reflects real operating conditions. The integrated design simplifies system configuration and operation while enabling more efficient and cost-effective evaluation of battery resistance to electrical interference during both R&D and quality inspection stages.
3.2 Low-Frequency Ripple Simulation Capability
The system upgrade focuses on the 1 Hz to 100 Hz low-frequency range, which is critical for simulating common disturbance sources such as power frequency fluctuations and industrial equipment harmonics.
Key characteristics include:
- Low-Frequency range: 1 Hz – 100 Hz
- Continuous adjustment with high control accuracy
- Frequency deviation: ≤ ±1 Hz
These capabilities enable precise and repeatable low-frequency ripple testing under controlled conditions.
3.3 Wide Ripple Amplitude Control
- Current ripple superposition range: ±1% – 100%
- Configurable according to system model and test requirements
- Suitable for a wide range of lithium cell performance and durability evaluations
4. Value for Battery Testing Applications
With this functional upgrade, the Nebula 2026 Cell Cycle Test System provides users with:
- Integrated cycle testing and ripple testing within a single system
- Reduced test system complexity and equipment investment
- Improved realism in battery performance evaluation
- Higher efficiency in battery R&D and quality testing workflows
By enabling composite testing that closely matches real operating conditions, the system supports more accurate assessment of battery performance, safety, and durability.
5. Driving More Realistic Battery Evaluation
This upgrade represents an important step toward more refined and application-oriented battery testing. Nebula will continue to focus on practical testing requirements and technological innovation, delivering reliable test systems that support the global battery industry in achieving safer, more stable, and more reliable energy solutions.
