Chroma Releases Regenerative Battery-Pack Test System
By Rick Nelson, Executive Editor, September 2012
September 5, 2012. Chroma Systems Solutions has announced the release of its new 17020 regenerative battery-pack test system. Chroma’s 17020 system is specifically designed for secondary battery module and pack testing. Accurate source and measurement capabilities ensure that the test quality is suitable for performing battery module/pack incoming or outgoing inspection as well as capacity, performance, production, and qualification testing.
Chroma’s 17020 test system features regenerative battery energy discharge, designed to recycle the electric energy sourced by the battery module. The energy is recycled to the channels in the system performing a charging function, or back to the utility mains. Saving electricity and reducing the facilities thermal foot print, this feature provides a green solution by reducing the environmental impact.
The battery test system comes equipped with multiple independent channels to support dedicated charge/discharge tests on multiple battery packs, each featuring discrete test characteristics. Channels can be paralleled to support higher current requirements, providing flexibility between high-channel-count and high-current testing.
Charge/discharge mode allows customers to simulate real-world scenarios. Advanced driving hardware creates seamless transitions from a maximum charge to a maximum discharge (or maximum discharge to a maximum charge) with a 10-ms conversion.
Chroma’s 17020 system comes equipped with flexible programming functions. Coupled with Battery Pro software, customers are able to create cycling tests from basic charge or discharge to complex drive-cycle testing for each channel or channel group. Thermal chamber control can be integrated into a profile and triggered by time or test results, yielding a dynamic profile.
Multiple safety features come standard, including battery polarity check, overvoltage protection, overcurrent protection, and over temperature protection. In the unlikely event of power or computer communication loss, data is securely stored in the system’s nonvolatile memory.
