Cell Specifications

For a given battery model, we can compute the mass, the capacity and the nominal energy without running any simulation. A CellSpecificationSummary object can be instantiated from a model to print all this information

We setup a model using runBatteryJson but with the option runSimulation set as false to avoid running the simulation.

jsonstruct = parseBattmoJson('JsonDataFiles/sample_input.json');
model = runBatteryJson(jsonstruct, 'runSimulation', false);

css = CellSpecificationSummary(model);

Then, using the printSpecifications method, we get an overview of the cell specifications

There exist separate functions to compute all this information separatly.

• computeCellMass computes the mass of the battery and its components

• computeCellCapacity computes the capacity of the the electrodes

• computeCellEnergy computes the total energy of the battery when discharged at equilibrium conditions. It means that the transport effects are totally neglicted and corresponds to the case of an infinitly small CRate.
