Energy Recovery Battery Module Test System Model 17020C

The Chroma 17020C system is a high-precision device designed specifically for secondary battery module and pack testing. It is suitable for battery module/pack range testing, inbound and outbound product inspection, design validation studies, and production on-line capacity learning (Learning) and testing.

Recycled energy design

The system recovers the power released during the discharge of a battery module and sends it back to other battery modules in the charging channel or back to the utility grid, thus saving power and reducing heat generation.

Multiple independent channel design architecture

The system supports exclusive charge/discharge testing of multiple battery modules/packs, with independent test characteristics for each channel. Channels can be connected in parallel to meet higher current requirements, providing flexibility between high channel counts and high current testing.

Flexible Programming Functions

The Chroma 17020C system is equipped with "Battery Pro-X" software, which provides flexible programming capabilities and an intuitive and easy interface for editing and executing test steps. The system provides graphical test flow creation, predefined test templates, real-time data monitoring, and seamless integration with external devices, which significantly improves the efficiency and accuracy of test configurations and meets all kinds of complex test requirements.

Backup Battery Unit (BBU) / Rack Testing

To ensure accurate BBU testing, the conversion rate of the test equipment must be minimized. with a ramp rate of 5ms (from 10% to 90%), the Chroma 17020C is the optimal solution for backup battery unit (BBU) and battery backup system (BBS) testing, providing precise control and reliable performance.

Current creepage rate

The system is equipped with a 10ms climb rate from -90% to +90%, which accurately simulates the driving state under dynamic driving conditions, ensuring the authenticity and reliability of the test results.

Safety Features

Multiple safety protection mechanisms are built into the system, including battery polarity checking, over-voltage protection, over-current protection, over-temperature protection and VDE-4105-AE islanding detection, etc., which comprehensively safeguard the safety of the testing process. The data saving mechanism can automatically store the data into the memory in case of computer abnormality or instantaneous power failure to avoid data loss and record the interruption status, which can be selected to continue the test after recovery. These features make the Chroma 17020C system an efficient and accurate all-round battery testing solution. Its flexible programming capabilities and intuitive operating interface make it easy to operate and fully meet the needs of different test scenarios.
