The EIS Box comes with 8 x 3 m cell cables and is designed to be used in conjunction with a battery tester/cycler to provide impedance testing. Cycle testing of the battery would be provided by the battery tester/cycler. It can be installed in a 19-inch rack (similar to the ECM8 multiplexer). Connection to the EIS Box is made through ethernet or USB. As with a USB connection to our potentiostats, the EIS Box has to be in constant contact with the host computer for experiments to be performed successfully. Connection via ethernet is done via a direct connection to the computer or over a local network only; connection over the internet is not possible.
Though the EIS Box was designed for single cell measurements of individual cells, it can measure voltages within a stack of cells. Each EIS Box channel can measure a +/- 5V cell whose maximum voltage does not exceed 28V versus ground. Additionally, the EIS Box cannot measure more than 28V total in a stack. For example, if you had eight or more 4.2V cells in a stack, the EIS Box cannot measure more than the first six in that stack.
