Precision Battery Cell Testing Solutions for Lithium Battery Production and R&D
Accurate and reliable cell testing is essential throughout lithium battery development and manufacturing. From initial formation and capacity grading to cycle-life evaluation and performance validation, every cell must be tested under controlled conditions to ensure consistency, safety and long-term reliability.
Shenzhen Brilliance Technology provides a comprehensive range of regenerative battery cell testing systems for cylindrical, prismatic and pouch lithium-ion cells. Our 5V testing platform supports different current levels and channel configurations, enabling customers to select a suitable solution for laboratory research, pilot production and high-volume battery manufacturing.
A Flexible 5V Battery Cell Testing Platform
Different battery cells require different testing currents, fixture designs and production capacities. Brilliance Technology offers a flexible 5V cell testing series covering current ranges from low-current capacity grading to high-current performance testing.
Typical configurations include:
- 5V6A multi-channel systems for cylindrical and pouch cell formation, capacity grading and cycle-life testing
- 5V60A systems for prismatic cell testing and medium-current performance evaluation
- 5V300A systems for high-current prismatic cell testing
- 5V600A systems for advanced high-current cell performance and cycle-life evaluation
Channel quantities can be configured according to the required current range, production capacity and testing application. Available solutions include high-density 512-channel systems, 64-channel prismatic cell testers and high-current multi-channel testing cabinets.
Main Testing Functions
Brilliance Technology battery cell testing systems support the principal processes required for lithium battery manufacturing and research:
Cell Formation
Programmable charging and discharging procedures activate newly manufactured battery cells and help establish stable electrochemical performance.
Capacity Testing and Grading
The system measures the available capacity of each cell and supports cell classification according to capacity, voltage and other test results. Accurate grading helps improve consistency when cells are assembled into battery modules and packs.
Cycle-Life Testing
Repeated charge and discharge cycles allow manufacturers and research laboratories to evaluate capacity retention, efficiency and long-term cell degradation under defined operating conditions.
Performance Evaluation
Programmable test profiles support the evaluation of cell voltage, current, capacity, energy and other performance characteristics under different charging and discharging conditions.
High Measurement Accuracy
Stable measurement accuracy is critical when comparing cells and identifying performance differences. Brilliance Technology cell testing systems provide voltage and current accuracy of up to ±0.05% F.S., depending on the selected model and configuration.
Four-wire measurement is used in suitable configurations to reduce the influence of cable and contact resistance. This helps improve measurement consistency, especially during high-current testing.
Regenerative Energy-Saving Operation
During conventional discharge testing, battery energy is often converted into heat and wasted. Brilliance Technology regenerative systems feed discharged energy back to the facility power supply for reuse.
Depending on the model and operating conditions, energy regeneration efficiency can reach 80% or higher. This reduces heat generation, air-conditioning requirements and electricity consumption, making the equipment more suitable for continuous operation and large-scale battery testing facilities.
Multi-Channel Testing for Higher Productivity
Each testing channel can operate according to an independently programmed test profile. Multiple cells can therefore be tested simultaneously under the same or different operating conditions.
High-density channel configurations help battery manufacturers increase testing capacity while making efficient use of production space. The modular system architecture also simplifies installation, maintenance and future capacity expansion.
Solutions for Different Cell Formats
Our battery cell testing systems can be configured for different lithium battery formats, including:
- Cylindrical cells
- Prismatic cells
- Pouch cells
- Lithium iron phosphate cells
- NMC lithium-ion cells
- Other rechargeable battery chemistries
Fixtures and cell-contact solutions can be customized according to cell dimensions, terminal structure and testing requirements.
For prismatic cells, motor-driven fixtures are available to automatically lower the test probes onto the battery terminals. This design simplifies loading and unloading, reduces repetitive manual operation and helps maintain consistent contact pressure during testing.
Intelligent Software and Data Management
The control software allows operators to create programmable charging and discharging processes, set protection limits and monitor test status in real time.
Test data can be recorded and exported for analysis and quality traceability. Depending on the project requirements, the system can also support barcode identification, database management and integration with production management systems.
