SI-9300R High Power and High Precision Energy Device Testing SystemFour major technical features:

Energy Reusable Technology

End users need to consider the ownership and testing costs of batteries. The SI-9300R multi-channel battery analyzer adopts energy reuse technology to reduce operating costs

Reduce testing costs

The energy recovery algorithm in the software can reflux current back to the grid or dynamically balance energy input and output in the same module, which can save 90% of energy compared to technologies that do not use energy return to the grid, greatly saving energy and costs.

space-saving

Due to the recycling of energy, the space used for cooling electronic components can be greatly reduced. This allows SI-9300R to increase its channel density by three times compared to systems without energy reuse. In the case of limited testing space, SI-9300 maximizes measurement capability while also maximizing experimental space savings.

Multi current range and flux valve sensing technology

This system uses multiple current ranges and flux valve sensors. These technologies are particularly suitable for high rate testing and low current charging measurements, and reducing testing costs will not compromise testing accuracy and precision. The temperature stability of flux valve sensing technology is improved by 5 times compared to shunt resistance sampling technology. Therefore, the measurement accuracy will not decrease due to temperature changes in the measurement circuit.

temperature measurement

Our PoE (Active Ethernet) - temperature measurement unit provides time stamped temperature or voltage measurements. Each analysis channel can be configured with up to 16 measurement inputs. Users no longer need to manually match temperature measurements with other data over time.

Hard disk direct writing technology

The SI-9300R battery analyzer uses revolutionary hard disk direct write technology to store data. In this system, the battery analyzer directly stores data to the central network hard drive without the need for computer processing. This not only improves the reliability of the system, greatly reduces computer data loading, reduces network congestion, but also maximizes the reduction of data transmission latency. Since the computer is no longer responsible for storing data, even if the computer experiences an unexpected shutdown, it will not affect the testing process. This can make the computer more focused on running its designed program functions, such as organizing test runs, system monitoring, and data analysis. Its additional benefit is that computers can be easily added, moved, or removed from the network without affecting the execution of tests.

SI-9300R comes standard with impedance function

Strong transmission force has incorporated frequency response analysis techniques into each measurement channel. Unlike expensive multiplexers, providing strong transmission power in each channel does not increase the cost of the system. In addition, the two auxiliary voltage measurement channels that come standard with each channel enable synchronous measurement of positive and negative impedance in the same battery. In addition to these, the SI-9300R multi-channel battery analyzer also provides real-time impedance data fitting during the testing process for real-time battery diagnosis.

NISSAN Leaf SoH Algorithm

Through collaboration with the School of Manufacturing Engineering at the University of Warwick in the UK, a SoH algorithm has been developed for NISSAN LEAF battery modules using strong transmission analysis. Unlike the time-consuming power pulse testing, our algorithm can provide the SoH of the battery within 3 minutes with an accuracy of ± 3%. This provides significant cost and time benefits for the grading testing required for the secondary utilization of batteries.
