The Chroma 17050 system is a versatile platform that can be equipped with DC sources of different power ratings to cover a wide range of applications. Designed for both global and regional markets, it accommodates diverse power configurations to deliver tailored charge/discharge test solutions, along with customized system integration and worldwide service support.
Energy Recycling
The system features regenerative technology that recovers the large amount of power normally dissipated as heat during battery cycling. This not only reduces energy consumption but also ensures stable test performance without introducing harmonic interference to other equipment. The recovered energy can be fed back to the grid for reuse, easing the load on power infrastructure, reducing thermal management challenges, and aligning with green energy policies.
Independent Channel Architecture
The system supports testing of multiple battery modules or packs simultaneously, with each channel providing independent test characteristics. Channels can also be paralleled to meet higher current requirements, offering flexibility between high channel-count testing and high-current applications.
Versatile Programming
The Chroma 17050 system, together with Chroma's Battery Pro X software, offers flexible programming with an intuitive interface for editing and executing test steps. The software supports graphical creation of test programs, predefined test modules, realtime data monitoring, and seamless integration with external equipment. These features make test configuration more accurate and more efficient, meeting the needs of demanding applications.
Battery Reliability Testing
The system features dedicated functions for evaluating the self-discharge rate of batteries during long-term storage, providing an indepth analysis of durability and performance. The resulting data provides critical support for subsequent applications.
High-Speed Response Capability
With Chroma's Battery Pro X software integrated with third-party hardware, abnormal conditions can be detected in real time, triggering charge/discharge protection to stop the test. Combined with a BMS designated by Chroma and a data logger, the system achieves sampling latency of less than 10ms. This capability supports battery performance prediction, degradation analysis, and protection parameter verification, while ensuring accurate test status monitoring, data recording, fault diagnosis, and safety protection.
Customized Integration with Chambers and Chillers
The system can be software-integrated with third-party chambers and chillers to achieve precise control of both temperature and humidity. This reduces fragmented operation across multiple devices, simplifies overall workflow, and effectively shortens setup and operating time.
With these features, the Chroma 17050 system delivers a high-efficiency, fast-response, all-in-one solution for battery testing. Channels can be used independently or paralleled to support different testing needs. The system also simplifies durability testing, enables temperature and humidity control, and provides flexible programming functions. Together, these capabilities make operation easier while fully meeting the requirements of diverse test environments.
System Features
Suitable for Space-Constrained Applications
The 17050 model can be configured to communicate with stand- alone units and DC sources designated by Chroma. With Chroma's Battery Pro X software, each channel can perform independent testing to meet a wide range of battery pack requirements. The system also supports integration with chambers and chillers, and unlike fixed rack-based setups, offers greater flexibility for use in space-limited test environments. A reference diagram is shown below.
Discharge Energy Recovery
- Energy can be recycled back to the grid or internal loads, with recovery efficiency >90%.
- Low heat output reduces air-conditioning demand and lowers operating costs.
- At rated power, the power factor (PF) exceeds 0.95.
The system delivers high power testing capability even in space- limited environments.
A single cabinet achieves a maximum power density of 106kW/m³ while weighing only 740kg, minimizing footprint and saving valuable floor space. Product dimensions are shown in the figure below.
Protection Features
- Overcharge voltage, overdischarge voltage, overcurrent, overtemperature, overcapacity, and short-circuit resistance protection.
- Reverse connection protection and line-loss protection (ΔV)
- Delta protection:
- –ΔV/+ΔV (voltage) protections
- +ΔI/–ΔI (current) protections
Precharge Circuit
The system also features a precharge circuit that prevents inrush current from damaging power components.
Battery Charge/Discharge Software – Battery Pro X
The 17050 test system pairs with Chroma's Battery Pro X software, which is designed to meet the diverse requirements of rechargeable battery testing with robust safety and stability. When abnormal conditions are detected, the system's charge/discharge protection automatically halts the test to ensure data integrity. In addition, the software provides flexible programming, fast response capability with data acquisition latency of less than 10ms, and comprehensive data protection. These functions prevent data loss caused by unexpected power interruptions while supporting secure storage and rapid recovery, delivering a highly synchronized and reliable testing solution.
