Programmable Lithium-Ion Battery Charge/Discharge Tester

Chroma Systems Solutions announces the release of its new 17200 Programmable Charge/Discharge Tester. Chroma's 17200 is a precision charge/discharge test instrument specifically designed for Lithium-ion secondary batteries. Chroma claims high accuracy output and measurement up to 0.02% ensures long term repetitive test results. The instrument is capable of supporting various charge/discharge test modes such as CV (Constant Voltage), CC (Constant Current) and CP (Constant Power). These optimized features are typically required to perform cell reliability verification (such as battery cycle life test), the study of material properties, product research and development, and production incoming / outgoing inspection, as well as balancing, quality control, and safety evaluation. Chroma's 17200 Tester also features long term stability suitable for life cycle testing, independent channels and more.

The 17200 can be paired with Chroma's redundant 62000B DC Power Supplies to ensure the continuity of extended duration analysis, such as life cycle testing. This innovative design assures the stability and continuity of each test. The 62000B was designed for work stations that are sensitive to power failures including system servers, burn-in, life-test or longevity testing that cannot be interrupted. In the unlikely event of a power supply failure, the parallel N+1 redundancy architecture assures continuous operation. Each power module is easily hot-swappable, eliminating down time.

Each module has en embedded CPU that allows for isolated instruction execution per channel. Once a test profile is created and transferred from the programming console, each channel can discretely operate and back-up the test results. The test results can be backed-up locally or uploaded to an external computer via Ethernet. Therefore, an overloaded network or a power outage will not compromise the data transfer.

Coupled with Chroma's BatteryPro software, customers gain access to flexible functions and programming that allows for the rapid creation of test recipes for individual or a group of channels, and as a single independent channel or as a high current paralleled channel set. The application field covers varied Lithium-ion battery or battery module characteristic tests, which were formulated to help customers meet the versatile test requirements for laboratory and manufacturing environments.

To ensure safety, the 17200 offers many protection features such as cell polarity check, over voltage, over current, over capacity and loop (contacts and current path) resistance monitoring. These important safety features are provided to safeguard each cell and its surroundings.
