The Chroma 17020C is a high-precision system designed for repeated and reliable testing of secondary battery modules and packs. Offering highly accurate sourcing and measurement, the 17020C is ideal for incoming and outgoing inspections as well as capacity, performance, production, and qualification testing.

Regenerative Discharge Capabilities

The test system efficiently recycles the energy discharged from a battery module, either from one channel to other charging channels or back to the grid, saving power and reducing thermal footprint.

Multiple Independent Channels

Supports dedicated charge/discharge tests on multiple battery modules or packs with distinct test characteristics. Channels can be paralleled for higher current requirements, offering flexibility between high channel count and high-current test.

Flexible Programming Functions

Operated with Chroma's user-friendly Battery Pro X software, which allows easy creation and execution of tests without needing advanced programming skills. Features include graphically aided test creation, pre-defined profiles, real-time monitoring, and integration with external equipment.

Backup Battery Unit (BBU) / Shelf Test

To ensure accurate BBU testing, it is essential that the slew rate of the testing equipment be minimal. The Chroma 17020C, with a slew rate of 5ms (transition from 10% to 90%), is an optimal solution for testing BBU and BBS, providing precise control and reliable performance.

Rapid Slew Rate

The 17020C features a -90% to +90% slew rate of 10ms, allowing it to replicate real drive profile conditions for accurate simulation of dynamic driving scenarios.

Safety Features

Includes Battery Polarity Check, Over Voltage Protection, Over Current Protection Check, Over Temperature Protection, and VDE-4105-AE Islanding Detection. Tested data is securely stored in non-volatile memory to prevent data loss during power or communication failures. With flexible programming functionality and user-friendly operating software, the Chroma 17020C provides a convenient, robust, and efficient solution for comprehensive battery test.
