Chroma's 17020 is a high precision system specifically designed for secondary battery modules and pack tests. Accurate sources and measurements ensure the test quality that is suitable to perform repetitive and reliable tests that are crucial for battery modules / packs, for both incoming or outgoing inspections as well as capacity, performance, production and qualification testing.
Chroma's 17020 system architecture offers regenerative discharge designed to recycle the electric energy sourced by the battery module ei ther back to the channel s in the sys tem performing a charging function or to the utility mains in the most energy efficient manner. This feature saves electricity, reduces the facilities thermal foot print and provides a green solution by reducing the environmental impact on our planet.
Chroma's 17020 system is equipped with multiple independent channels to support dedicated charge / discharge tests, on multiple battery modules / packs, each with discrete test characteristics. The channels can easily be paralleled to support higher current requirements. This feature provides the ultimate flexibility between high channel count and high current testing.
Advanced hardware design can create seamless transitions between maximum charge and maximum discharge (or maximum discharge and maximum charge) with a rapid 50 ms conversion. This feature allows for charge/discharge modes simulating real world scenarios.
Chroma's 17020 system has flexible programming functions and may be operated with Chroma's powerful Battery Pro software. Battery Pro utilizes the system to create cycling tests from basic charge or discharge to complex drive cycle testing for each channel or channel groups. A thermal chamber control can be integrated into a profile and triggered by time or test results yielding a dynamic profile. Battery Pro's features allows quick and intuitive test development to eliminate the need of tedious scripting or programming by a software engineer.
There are multiple safety features including Battery Polarity Check, Over Voltage Protection, Over Current Protection check and Over Temperature Protection to ensure protected charge / discharge testing. In the unlikely event of power or computer communication loss, the data is securely stored in the system, on a non-volatile memory, protecting against potential data loss and allowing for continuous flow after restart.
