The Chroma 17020C is a high-precision system engineered for repetitive and reliable testing of secondary battery modules and packs. With its highly accurate sourcing and measurement capabilities, the 17020C is ideal for incoming and outgoing inspections, as well as capacity, performance, production, and qualification testing.
Regenerative Discharge Capabilities
The 17020C system efficiently recycles energy discharged from battery modules, either transferring it to other charging channels or feeding it back into the power grid. This design reduces energy consumption and minimizes heat generation, offering both cost savings and environmental benefits.
Multiple Independent Channels
The system supports dedicated charge/discharge testing on multiple battery modules or packs, each with unique test profiles. Channels can be paralleled to meet high current demands, offering ultimate flexibility between high channel density and high-current testing.
Flexible Programming Functions
Operated via Chroma’s intuitive Battery Pro X software, the system allows users to easily create and execute tests without requiring advanced programming knowledge. Features include:
Graphical test profile creation
Pre-configured templates
Real-time data monitoring
Seamless integration with external devices
Backup Battery Unit (BBU) / Shelf Testing
The Chroma 17020C ensures precise BBU and BBS testing, thanks to its fast 5ms slew rate (from 10% to 90%). This enables accurate and reliable testing of battery backup systems with minimal response delay.
Rapid Slew Rate Performance
With a slew rate capability of -90% to +90% within 10ms, the 17020C can simulate dynamic driving scenarios and real-world power profiles with high accuracy—making it ideal for automotive and mobility applications.
Advanced Safety Features
Safety is built into the system, with features including:
Battery Polarity Check
Over Voltage Protection (OVP)
Over Current Protection (OCP)
Over Temperature Protection (OTP)
VDE-4105-AE Islanding Detection
All test data is securely stored in non-volatile memory to prevent data loss in the event of power outages or communication errors.
Conclusion
Combining advanced functionality, rapid response, and user-friendly operation, the Chroma 17020C delivers a robust and efficient solution for comprehensive battery testing needs.
