Regenerative Battery Pack Test System

24 September 2012 - The Chroma 17020 System is a high precision integrated solution specifically designed for secondary battery module and pack tests. Accurate source and measurement ensure the test quality that is suitable for performing exact, reliable testing crucial for battery module / pack incoming or outgoing inspection as well as capacity, performance, production and qualification testing.

The system architecture offers regenerative discharge energy design to recycle the electric energy sourced by the battery module / pack to channels in the system performing a charging function or back 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.

It is equipped with multiple independent channels, to support dedicated charge / discharge tests on multiple battery modules / packs each with discrete test characteristics. Channels may be easily paralleled to support higher current requirements. This feature provides the ultimate flexibility between high channel count and high current testing.

Advanced driving hardware can create seamless transitions between a maximum charge to maximum discharge (or maximum discharge to maximum charge) with a rapid 10mS conversion. This feature allows for charge/discharge modes simulating real world scenarios.

The Chroma 17020 ATS has flexible programming functions that can be operated with Chroma's powerful "Battery Pro" Software (pictured below). 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. Thermal chamber control can be integrated into a profile and triggered by time or test results yielding a dynamic profile. Battery Pro's features allow quick and intuitive test development eliminating the need of tedious scripting or programming by a software engineer.

Multiple safety features are standard 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, data is securely stored in system non-volatile memory protecting against potential data loss and allowing for continuous flow after restart.

The green products should always apply the concept of environmentally friendly for production and testing. The 17020 system power regenerative architecture is able to recycle the discharged battery power to mains or to transfer it to the battery needs to be charged to solve the discharge energy wasting problem. It not only brings huge economic effect to the user by resolving the workspace heat treatment problem but also meets the carbon reduction and environmental protection requirements. The system provides a real environment-friendly battery test for testing the electric motorcycles and electric bicycles.
