Chroma ATE, a global provider of precision test and measurement solutions, strengthens its battery test portfolio with advanced battery cell charge and discharge testing systems designed to support the full lifecycle of lithium-ion battery development, from early-stage research and characterization to production validation and quality assurance.
As battery technologies evolve to meet the increasing demands of electric vehicles (EVs), energy storage systems (ESS), and consumer electronics, the need for accurate, repeatable, and safe charge/discharge testing has become critical. Chroma’s battery cell testing platforms are engineered to deliver high-precision electrical measurement, robust safety protection, and flexible test control, enabling manufacturers and research institutions to gain deeper insight into cell performance, degradation behavior, and safety margins under real-world operating conditions.
High-Precision Charge and Discharge Measurement
Chroma’s battery cell charge/discharge solutions are built using low-noise, high-accuracy power conversion architectures that ensure precise current and voltage control across a wide operating range. This level of accuracy is essential for evaluating key battery parameters such as capacity retention, coulombic efficiency, internal resistance evolution, and cycle life performance. By minimizing measurement uncertainty and drift, Chroma’s systems support consistent data generation across long-duration aging and cycling tests.
Integrated Safety and Environmental Control
Battery testing involves thermal, electrical, and chemical risks. Chroma addresses these challenges through multi-layer safety mechanisms, including hardware-level protections and software-based fault detection. The systems are designed to integrate seamlessly with environmental chambers, enabling synchronized control and safety interlocks during temperature-dependent testing. In the event of abnormal conditions, automated responses help mitigate risks to both personnel and equipment, making the platforms suitable for unattended long-term testing.
Chroma’s battery test platforms feature a modular and expandable channel architecture, allowing users to scale test capacity based on application requirements. This flexibility makes the systems equally suitable for laboratory R&D environments, where detailed characterization and experimental testing are required, and for manufacturing settings, where throughput, repeatability, and traceability are critical. Multi-channel configurations enable parallel testing of multiple cells while maintaining independent control and data integrity for each channel.
Advanced Software for Test Automation and Data Analysis
The systems are operated through Chroma’s proprietary battery test software, which provides an integrated environment for test configuration, execution, and monitoring. Users can define standard charge/discharge profiles such as constant current (CC), constant voltage (CV), and CC-CV, as well as more complex dynamic waveforms that replicate real application load conditions. Real-time data visualization and comprehensive logging functions support detailed post-test analysis, enabling engineers to extract actionable insights from large datasets.
By combining precision measurement, intelligent safety design, and flexible software control, Chroma’s battery cell charge/discharge testing solutions support a wide range of applications, including cell performance benchmarking, life-cycle testing, reliability assessment, and compliance verification. These capabilities are increasingly important as battery chemistries diversify and performance expectations continue to rise across automotive and stationary energy storage markets.
