EIS Box

Sequential impedance measurement of 8 cells is possible

The EIS BoxTM is a multiplexed eight-channel device designed for impedance measurement of batteries (or other devices such as supercapacitors or fuel cells), usually in conjunction with battery charge-discharge cycling equipment. Ground isolated, EIS frequency range from 100 kHz to 10 μHz, with 3U 19'' rack mount base.

  • Can measure up to 8 battery EIS
  • 10 µHz to 100 kHz*
  • 3 m electrode wire included
  • Ethernet based
  • Up to 6 V per channel

*Specifications are subject to the actual product
*Only support Windows 10 operating system

系统特点

The EIS Box comes with 8 x 3 m electrode leads and is designed to be used with a battery tester/cycler to provide impedance testing. Cycling testing of batteries is provided by a battery tester/cycler. It can be mounted in a 19" rack (similar to the ECM8 multiplexer). The connection to the EIS Box is via Ethernet or USB. When connected to our electrochemical workstation via USB, the EIS Box must be continuously connected to the test computer in order to ensure a successful experiment run. The Ethernet connection is made through a direct connection to the computer or only through a local area network; not through the Internet.

Although the EIS Box is designed for single cell measurements, it can also measure the potential within the stack. Each EIS Box channel can measure a +/-5V battery, and the maximum potential of the battery cannot exceed 28V to ground. In addition, EIS Box cannot measure stacks whose total potential exceeds 28V. For example, if your stack contains 8 or more 4.2V cells, the EIS Box cannot measure more than the first 6. Please contact us if you would like to know more about this particular application.
