The Chroma 17010H Battery Reliability Test System is high-precision charge and discharge test equipment specifically designed for high current/high power performance testing. This system is suitable for performance evaluation, life cycle testing and product selection of large Lithium-ion Battery Cells (LIB Cells), Electric Double Layer Capacitors (EDLCs) and Lithium-ion Capacitors (LICs).
The 17010H's energy recovery circuit architecture offers a marked improvement over traditional switching power supply equipment. It features high measurement accuracy and precision, high-speed current response, zero-crossover time for charge/discharge conversion, as well as multiple current ranges. These characteristics enhance the accuracy of battery cell capacity tests, improve performance parameter validation, and facilitate realistic dynamic current and power testing. In addition, Chroma 17010H features a powerful 30-second 200% pulse current output function. For instance, a unit with a single-channel continuous current of 300A can produce a 30-second 600A pulse current. This provides a highly cost-effective and space-saving solution for applications such as power capability and DC internal resistance testing, which require short but high-rate test currents.
High-current life cycle tests highlight the importance of testing the equipment's energy conversion efficiency. Benefits include not only reduced power demand, but also a large decrease in heat production. The control circuit operates at a relatively low temperature, effectively suppressing thermal drift and extending components' life cycles. In this way, the 17010H achieves accurate and stable test performance. Compared with linear circuit products, it offers more efficient energy conversion and higher power density, reduces power distribution requirements for laboratories, saves operating power and air conditioning costs, and improves space utilization.
Designed with the diversity of battery cell products and experiments in mind, Chroma 17010H features a channel parallel function with a continuous current up to 2400A and a pulse current up to 4800A. The performance of paralleled channels remains unchanged, with the exact same precision specifications and no response delay, significantly enhancing the equipment's applicability.
With regards to safety, each channel is additionally equipped with Level 2 V. Protection, and an independent measurement loop prevents battery overvoltage when a single component fails, enhancing testing safety. In addition, the system's product maintenance design has been improved: the circuit units are modularized and can be individually assembled and disassembled quickly, enabling convenient maintenance and channel backup.
