What does the Capacity Throughput show? The capacity throughput corresponds to the number of discharged ampere hours. The simulator displays the ampere hours reached at the end of the simulation in relation to the nominal capacity throughput. A high value indicates that the battery is well utilized.
What is a Full Equivalent Cycle? The ratio of discharged ampere hours to nominal capacity is called Full Equivalent Cycle (FEC). For example, if you charge/discharge a battery at 50Ah for three days and the nominal capacity is 100Ah, then you have reached 1.5 FEC.
What are the optimal operating conditions for the battery? The lowest possible calendrical aging (storage) is achieved at SOC 10-40% and low temperatures. For cyclic aging, a temperature range of 20-25°C is ideal, the SOC edge areas (completely empty) should be avoided. Depending on the type of battery, there are also areas with increased cyclic aging in the SOC 55-80% range. We are happy to support you with further battery know-how to get the maximum out of your application.
Can the model be adapted to a specific cell? We will of course be happy to adapt the model to your cell. For this purpose, we usually use test series on battery test benches. We will gladly organize the corresponding tests for you. As a future option, we would like to adapt our algorithms to the real-time data in a self-learning manner.
Why is it not possible to set the C-rate in the simulator? The simulation runs with a fixed C-rate of 0.5C. The current carrying capacity varies greatly from cell to cell, general statements are only possible at low C rates.
Why can't negative temperatures be simulated? Most lithium batteries may only be charged at positive temperatures, otherwise lithium plating will occur. This simplified simulator works with symmetric cycles at a single operating point, therefore no negative temperatures are possible.
How do I proceed to simulate more complex situations? Would you like to simulate, for example, a complex current profile over an annual temperature distribution? Please contact us, we will find a solution.
The life span is one of the most urgent questions for the economy of battery applications, with the Teaser is to be pointed out the authority in the range. Our scientifically supported simulator let's you explore the impact of different factors on the life span of a battery.
The State of Health Simulator shows the course of the residual capacity for a typical lithium cell with graphite anode like NMC, NCA or LFP at low C-rate. You can adapt the simulator to your cell regarding cycles and calendar aging.
