The Chroma 17060 is a high-power-density charge/discharge system developed specifically for rechargeable battery pack testing. It combines high precision with energy recovery capability and adopts a modular power architecture. Different power modules can be flexibly configured in series and/or parallel under specified conditions to provide multiple power-channel options. With high scalability and flexible system integration, the system can meet battery testing requirements across a wide range of applications.
The 17060 features energy recovery capability to reduce the large amount of electrical energy otherwise consumed during battery discharge. Even under dynamic charge/discharge conditions, the system maintains stable grid-side operation without harmonic interference affecting other equipment. Energy discharged from the battery pack can be recovered and fed back to the grid for reuse, reducing the energy waste and heat dissipation issues associated with conventional discharge equipment while supporting environmental requirements.
The system adopts a modular architecture, allowing power modules to be configured in series and/or parallel according to test requirements to meet different power, voltage, and current ranges. Flexible series/parallel channel configuration allows the system setup to be adjusted according to test power requirements and supports battery validation solutions up to the megawatt level, reducing initial capital investment. This architecture flexibly accommodates different test power requirements while maintaining high scalability and application flexibility.
When paired with Chroma Battery Pro X software, recipe test steps support multi-variable calculations and conditional logic. Test conditions can be dynamically adjusted according to signals returned by the battery pack or BMS, enabling diverse and complex test scenarios. Enhanced data analysis tools also support importing and comparing multiple datasets, rapid curve generation, and customized report data.
Multiple protection mechanisms designed for battery testing automatically detect overvoltage, overcurrent, and external signals to maintain safety and stability throughout the test process. If an abnormal condition is detected on any channel, charge/discharge operation is stopped for protection. Data retention after power interruption and test recovery functions further help prevent data loss.

System Features
Designed for high-power rechargeable battery pack testing, the Chroma 17060 Battery Pack Test System combines high power density with high-precision measurement capability. Its regenerative technology feeds energy back to the grid for reuse, effectively reducing energy consumption and improving overall energy efficiency. The system adopts a modular architecture that allows power stages to be configured in series and/or parallel according to test requirements, providing flexible multi-channel expansion capability.
Modular High-Power Architecture & Energy Regeneration
The Chroma 17060 uses a modular bidirectional DC power architecture and provides two power stages: the 69605-850-200 (50kW) and 69615-850-500 (150kW). Power stages can be flexibly configured and the system power rating expanded according to test requirements. The 50kW module provides up to 850V and 200A output, while the 150kW module provides up to 850V and 500A output, maintaining reliable output capability under either high-voltage or high-current conditions. Both power stages use a 3U design to deliver high power density within limited rack space and optimal space utilization. The modular architecture enables flexible expansion according to test requirements, improving overall configuration and integration efficiency. The 17060 also provides discharge energy recovery, returning energy generated during testing to the grid and improving overall energy utilization in high-power test environments.
Flexible Hardware and Software Integration
Chroma’s Battery Pro X software allows integration with third-party hardware, enabling charge/discharge protection to kick in and automatically stop the test when abnormalities are detected. The software can also integrate third-party chambers and chillers for temperature and humidity control, reducing fragmented operation across devices resulting in more streamlined workflows. Data from these devices can be incorporated into test procedure control to support integrated test solutions.
- Chamber: Temperature and humidity control integrated with charge/discharge procedures
- Chiller: Water temperature, flow, and pressure control for simulating various operating conditions
High Precision – Precise Measurement Improves Product Quality
The system features automatic voltage range switching with multiple measurement ranges. As the voltage changes dynamically, the system automatically switches to the appropriate range to optimize measurement accuracy.
- Voltage accuracy: ±0.02% of range
- Current accuracy: ±0.02% of F.S
High-Frequency Sampling Accurately Captures Battery Pack Capacity
The high-frequency sampling measurement technology provides a sampling rate of up to 50kHz to ensure dynamic measurement accuracy. Conventional battery charge/discharge systems directly use current values read by software for capacity calculation. However, limitations in software data reading speed can result in excessive capacity calculation errors under dynamic current conditions. By increasing the V/I sampling rate and using a double-integration method, the Chroma 17060 provides accurate capacity calculation without missing data during current changes and without being affected by the data transmission rate.
- V/I sampling rate: 50kHz (one sample every 20µs)
Fast-Response Testing for Battery Pack Verification
The Chroma 17060 supports Waveform testing for dynamic operating condition simulation, reproducing the current or power profiles of actual driving conditions. It supports test standards such as NEDC, FUDS, and HPPC. With fast current response and optimized charge/discharge mode switching, the system provides smooth transitions without current surges, helping prevent damage to the DUT during testing.
- Current switching time: 4ms (-90% to 90%)
Safety – Bidirectional Circuit Architecture for Power Protection
The system adopts a bidirectional circuit architecture to achieve efficient discharge energy recovery. It precisely controls the forward and reverse flow of AC current, maintaining a smooth AC current waveform with real-time phase transitions. The design complies with grid requirements to prevent interference with other grid-tied equipment. When an abnormal grid condition is detected, the system actively disconnects the main circuit power to ensure safety.
- I_T.H.D <3% @400VAC
- PF >0.99 @400VAC
- Max. Recycle Efficiency > 94%
Integrated Hardware Enhances Battery Pack Test Safety (Option)
The Chroma 17060 integrates software, a BMS data acquisition device, and a data logger through a middleware architecture to improve communication efficiency and achieve communication latency of less than 10ms, further enhancing safety protection and monitoring capability for battery pack testing. When used with the designated battery management system (BMS) data acquisition device, the system can read multiple sets of BMS data through communication interfaces such as CAN (FD) during charge/discharge testing. The acquired data can be used to configure protection parameters, helping ensure battery pack test status monitoring, data recording, fault diagnosis, and safety protection. When used with the designated data logger, the system can measure the voltage and temperature of multiple battery cells or modules during charge/discharge testing, and the measurement data can be used for protection condition settings.
- BMS Data Acquisition Device: Uses the Chroma 80700-5/80700-11 standard mainframe integrated with the A692017 4CH CAN (FD) bus communication card module for battery pack BMS communication and data acquisition. Test channels can be bound to BMS signals to monitor battery pack status while synchronously acquiring and recording DUT data. Charge/discharge conditions can also be dynamically adjusted based on real-time BMS signals, with cutoff and protection logic executed accordingly to better meet practical test requirements and reduce the risk of abnormal testing.
- Data Logger: Measures the voltage and temperature of battery cells or modules for use in protection condition settings.
