SI-9300R Battery Analyzer

The SI-9300R battery analyzer is a complete solution for the characterization of high energy and power cells. More than just a battery cycler, it includes unique measurement and analysis features that are specifically designed to help accelerate materials research, support battery health/battery capacity analysis, and better understand performance issues that may arise in the service.

 

SI-9300R is a modular system in which each module consists of five independent measurement channels. Each channel is rated at 3 kW and can deliver current pulses up to 300 amps (200 amps continued). Each channel performs the same basic function of the battery cycler, but includes additional functions aimed at developers in HEV, PHEV and eV Second Life applications.

 

regenerative technology

 

The SI-9300R Battery Analyzer incorporates low-energy return-to-grid (RTG) technology in which excess power from discharging cells is returned to the mains or recycled within the system, reduces operating costs by up to 90% compared to non-regenerative technology. . RTG also reduces cooling requirements, allowing the SI-9300R to occupy as little as a quarter of the volume of non-regenerative systems, ideal where floor space is at a premium.

 

Multiple current ranges

 

Unlike single current range instruments that lose accuracy at low power tests, the SI-9300R Battery Analyzer uses a novel multi-range current sensor, enabling development work at high C-rate and low without loss of accuracy and precision. The system is equally well-suited for testing eV bag and prismatic cells, while providing tools to turn 18650 and 21700 form factor cylindrical cells on and off, with application in end-of-line testing, conduction cycle testing, and hybrid pulse power characterization. Multiple current range modules allow greater test flexibility with reduced space requirements.

 

Impedance measurement as standard

 

The system includes a dedicated Solartron frequency response analyzer on each channel, providing high-speed/high-accuracy EIS analysis of all cells under test. In addition, for cells that have a third electrode, anode/cathode analysis is also provided via EIS-enabled auxiliary channels.

 

Real-time data analysis

 

The system software makes extensive use of EIS modeling which provides real-time updates during test runs to enable continuous analysis of cell trends. This can be extended to rapid SoC/SoH analysis using proprietary algorithms essential for cell classification and other time-sensitive SoH applications.

 

Direct to disk technology

 

Conventional battery cycler systems use PCs to transfer data from battery cycler channels to disk. In contrast, SI-9300R uses advanced technology to write data directly to disk without the intervention of one PC. For systems with high channel counts, this drastically reduces the workload on the PC, increases system reliability, and allows PCs to focus on test control, channel monitoring and data analysis.
