The Current Challenge
Battery manufacturers often present cycling graphs that look promising — smooth curves, high retention, and long lifetimes. But in many cases, these are generated from simulated data or based on standardized “ideal” test conditions that don’t reflect the real world.
In short: cycling graphs alone are not enough to guarantee reliability. Real-world conditions — high/low temperature, overcharge, short circuit, thermal runaway — need to be simulated and tested in a controlled lab environment.
Our Testing Package
To address this gap, Sinovoltaics has developed a Battery Cell Reliability Testing Package. Our goal is to provide verifiable insights into your battery’s true performance and safety profile before it reaches the field.
What We Test & Why It Matters
Our package combines a series of laboratory tests designed to expose potential weaknesses in battery cells:
1. Appearance, Polarity, and Mass Checks
Detect early signs of manufacturing defects or internal inconsistencies.
2. Charge/Discharge Energy Tests
Validate energy retention and efficiency under multiple conditions.
3. High & Low Temperature Adaptability Tests
Assess performance recovery after exposure to extreme climates.
4. Multiplier Charge/Discharge Tests
Stress-test the cell under high current loads to reveal weaknesses in design.
5. Overcharge & Over-Discharge Tests
Identify hidden risks of swelling, leakage, or irreversible damage.
6. Short Circuit Test
Simulate a real-world accident and verify the cell’s fail-safe mechanisms.
7. Thermal Runaway Test
Examine the most critical failure mode: whether the cell can contain extreme heat without catastrophic explosion or fire.
Each of these tests is designed not only to verify performance, but also to reveal failure mechanisms that manufacturers’ standard cycling graphs typically overlook.
Why Work With Sinovoltaics?
- Independent Verification – Results you can trust, not marketing graphs.
- Comprehensive Testing – Covering thermal, mechanical, and electrical stress.
- Bankability & Risk Reduction – Essential data for developers, EPCs, and investors before large-scale deployment.
- Highest International Standards – Testing executed to the highest international standards.
