There are more features in this software platform when it is operated in advance mode, allowing the expert complete control of the instrument.
Intuitive and easy linear battery testing protocol builder, with real-time interactive user control, safety settings, cycling protocol, drive cycle import.
CycliScan is designed with the battery scientist in mind, or those who are involved in energy storage research. It is a straight-forward protocol builder that uses a linear structure, offering complete control and customization on all levels, as well as real-time.
Safety is taken care of by the global and local settings for each stage of the protocol, making the software reliable for peace-of-mind operation. Cycles can both be included in the protocol, and as an overall parameter to facilitate duration testing. For the more demanding protocols, drive cycles can either be easily imported, or simply created from the available cycle builder.
Clear and simple control of up to 100s of channels simultaneously with only a few mouse clicks.
MC mode caters for our users who have a high-channel count system and is designed to allow no-nonsense channel management.
With parallel measurement of >100 channels, MC Mode gives a clear overview of those channels which are active, those which are grouped, and those which are available. In addition, with a few simple clicks, the handling of these channels is fast and efficient. Ideal for the researcher with multiple cells, or the production engineer with high volumes of cells.
IviLAB is the perfect partner to use in combination with CycliScan and MC Mode. It offers advanced data handling for large or multiple data sets, with a versatile approach to displaying in a manner than suits your requirements.
IviLAB allows the data from multiple channels to be plotted separately or on one graph, overlaying of selected cycles for direct comparison, customized graphs and representation, and an overview of all measured data in a concise and ordered format.
Plots such as charge-discharge, capacity vs. cycle number, EIS fit, charge efficiency, and many more are possible with this powerful analysis tool.

Multiple views of the measurements can be used to display the graph as various representations. In the case below, an EIS measurement shown as both the Bode and Nyquist plots.
IviumSoft Special functions:
Automatic current ranging
When desired, the user can instruct the potentiostat to automatically select the optimal current range setting. For this functionality all current ranges are available, including the hi-sensitivity current ranges.
Apply wrt OCP
The measurement potentials are defined relative to “Open Cell Potential”. Before the measurement starts, the OCP is determined in a zero-current configuration.
Analog inputs
The available analog inputs from the peripheral port may be recorded simultaneously with the primary results. The results are visualized graphically, and stored with the primary data.
Pulse generator
A continuously repeating pulse can be applied to the cell with variable period and duty cycle; intended as a tool to treat the electrode without data being measured.
Pretreatment
Up to 5 levels may be defined to condition the electrode before the actual measurement starts. The E/I values during “Pretreatment” are recorded and stored with the primary data.
Ohmic drop compensation
Manual or automatic Ohmic drop compensation
Current interrupt
Direct method that allows the user to determine the IR-drop of the electrochemical system via the current interrupt method (can only be used when Current Interrupt Module is available)
Signal view
The current and potential transients are shown in an oscilloscope type screen. Under dc-conditions, the E/I signals can be inspected for the presence of specific noise elements. During ac-techniques, the quality of the perturbing and resulting sine-waves is visualized. For each data point these traces are stored with the primary data and can be (re)viewed after completion of the experiment.
