As power demands continue to surge across AI data centers, electric vehicles, and energy storage systems, requirements for power quality and dynamic response are becoming increasingly stringent. Traditional battery testing methods that focus mainly on charging and discharging can no longer support real-world application needs. Accurate evaluation of system performance and safety risks now requires the integration of multidimensional data, including voltage, current, BMS (Battery Management System) signals, and ambient temperature.

However, current long-duration life cycle test architectures typically rely on DC power supplies and electronic loads for charge/discharge operations, combined with BMS, thermal chambers, and external data loggers. These systems are controlled sequentially via SCPI commands from a host computer, resulting in a distributed, polling-based architecture. Without real-time data integration and synchronization, testing relies heavily on post-processing—leading to data misalignment and loss of transient information. This has become a critical bottleneck affecting both testing accuracy and efficiency. Key challenges include:

• Misaligned Data Time Axes
  Data collected from multiple devices is not synchronized, requiring manual alignment during post-processing and increasing the risk of analytical errors.
• Communication Latency Impacts Protection Decisions
  The SCPI query-response control model typically has a response time of around 100ms. When the system must wait for BMS status feedback before making a protection decision, it may delay protective actions and increase the risk of missing transient data.

From Data Integration to Testing Efficiency: Reducing Validation Costs

To overcome the challenges of fragmented data and insufficient real-time responsiveness, the Chroma 17050 Battery Pack Test System adopts a middleware architecture. This design integrates data acquisition, test monitoring, low-latency protection, and automated reporting, effectively reducing cross-device integration complexity while enhancing both testing efficiency and system reliability.

Within this architecture, a CAN bus polling and broadcast mechanism is used to control the Chroma 62000D series bidirectional DC power supply for battery charging/discharging and data acquisition. Command communication time is reduced to 20ms, enabling the system to obtain real-time power output status and execute control actions efficiently.

At the same time, the system integrates BMS data and data logger measurements to evaluate step termination conditions and protection criteria. With the middleware architecture reducing communication latency to within 10ms, real-time data acquisition combined with hierarchical control enables the system to detect and respond to state changes in the DUT (device under test) immediately.
Compared to traditional sequential decision architectures that are host-controlled, the Chroma 17050 effectively eliminates data synchronization issues and protection delays, reducing the risk of transient data loss while improving testing safety, data integrity, and reliability of analysis results. 

▲Chroma 17050 Middleware Architecture: Enabling Multi-Device Integration and Real-Time Decision Making

The Chroma 17050 is an integrated battery pack test platform that combines high-power bidirectional DC power supplies with a flexible software architecture, delivering comprehensive test control and data analysis capabilities.

• Hardware Architecture
  The system incorporates the Chroma 62000D bidirectional DC power supply, supporting multiple voltage levels (100V / 600V / 1200V / 2000V) with currents up to approximately 10,800A (depending on configuration). It also supports parallel operation to scale for high-power applications (12–45kW per unit, expandable further via parallel connection). Additionally, it features energy regeneration capabilities (efficiency >90%, power factor >0.95), allowing discharged energy to be fed back into the grid, which significantly reduces energy consumption and thermal management load.
• System Integration Capabilities
  The platform supports integration with BMS, thermal chambers, and external data loggers, offering multi-channel voltage and temperature measurements. Leveraging the middleware architecture, it enables low-latency control (<10ms) for real-time execution of termination conditions and protection logic, improving both testing safety and data synchronization.
• Software Features
  Paired with the Battery Pro X platform, the system provides flexible test programming and an intuitive graphical interface. It supports CC/CV/CP modes, cycle testing, and dynamic condition simulation, along with real-time monitoring and automated report generation, enhancing testing efficiency and data visualization.
