It’s no secret that Chroma ATE provide a wide variety of world leading test and measurement products and solutions. With so many products to shout about, we’ve decided to start highlighting some of them, with their features and uses in this new series.
Our focus for this highlight: the 17011 Programmable Charge/Discharge Tester, the 17020 Regenerative Battery Pack and the 17040 Regenerative Battery Pack Test System
The 17011 Programmable Charge/Discharge Tester
This high precision system was designed specifically for testing lithium-ion battery (LIB) cells, electrical double layer capacitors (EDLC), and lithiumion capacitors (LIC).
Suitable for product development, quality control, and helpful to characteristic research, cycle life testing, product screening, and quality assessment. The Chroma 17011 has developed linear circuit and regenerative AC/DC bidirectional test systems for different applications.
The regenerative bidirectional test system with high efficiency, power saving, low heat, and stable measurement capabilities is applicable for testing energy storage components in medium and large size or power type battery cells to meet the low carbon emission production for the green energy industry.
In addition to the commonly used constant current (CC), constant power (CP), constant voltage (CV), constant resistance (CR), and rest test modes, Chroma 17011 is also equipped with waveform simulation functions and test items including DCIR, HPPC, EDLC capacitance, and EDLC DCR to comply with the international standards that made programs editing and test results analysis much easier.

The 17020 Regenerative Battery Pack Test System
Chroma’s 17020 is a high precision system specifically designed for secondary battery module and pack tests. Highly accurate sources and measurements ensure that the test quality is suitable for performing repetitive and reliable tests crucial for battery modules/packs, incoming, and outgoing inspections as well as capacity, performance, production, and qualification testing.
The Chroma 17020’s advanced hardware design creates 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 that simulate real world scenarios.
The Chroma 17020 system has 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, data is securely stored in system non-volatile memory protecting against potential data loss and allowing for continuous flow after restart.

The 17040 Regenerative Battery Pack Test System
The Chroma 17040 Regenerative Battery Pack Test System is a high precision system specifically designed for secondary battery module and pack tests. It has an energy regenerative function to greatly reduce power consumption during discharge, and ensure a stable power grid without generating harmonic pollution on other devices – even in dynamic charge and discharge conditions.
It is capable of recycling the electric energy discharged by the battery module back to the grid reducing wasted energy that is discharged by traditional equipment in the form of heat, thus reducing the HVAC requirements.
Equipped with Chroma’s powerful “Battery Pro” software, the 17040 system has flexible test editing functions to perform independent channel tests, and conforms to the diversified requirements for testing secondary battery packs with high safety and stability. It also supports power failure recovery functions that ensure test data is not interrupted.
The test system has multiple safety features including Over Voltage Protection, Over Current Protection Check, Over Temperature Protection, and external parameter detection to ensure protected charge/discharge testing on the batteries. Furthermore data loss, storage and recovery are protected against power failure
