This is how battery simulation works
What is battery simulation?
Battery simulation is used to model a battery’s electrical behavior in a virtual environment. This makes it possible to study the battery performance without requiring a real battery. The simulation allows for predicting a battery’s behavior under different conditions, contributing to improving the battery’s design and extending its life.
How is the optimum battery simulation developed?
To enable optimum modeling of a system in the battery simulation, the appropriate modeling approach and the acceptable model simplifications need to be selected. In this process, optimum alignment to the requirements of the specific objective and the respective system is crucial. In addition, cost-benefit considerations may also play a role.
After choosing the appropriate approach, the challenges in developing the optimum battery simulator are model development, testing, implementation and parameterization.
What does a battery simulation model comprise?
- Equations or systems of equations
- Input parameters (e.g. current and ambient temperature) and output parameters (e.g. voltage) that are calculated based on the underlying equations and the current state of the battery (e.g. SOC)
- Parameters that differ for the specific batteries – parameters can be provided in the form of characteristics to update them during the battery simulation, for example according to temperature, or the physical processes are depicted
In the white-box approach, the physical or electrochemical processes in a battery are simulated using partial differential equations, with each model parameter having a physical meaning. This makes it possible to gain insights into the systems of the battery that would not be possible without a simulation model.
The development of such a model requires a profound understanding of the energy storage system.
The BaSiS models have been developed based on the white-box approach.
- describes the non-linear battery behavior across the entire operating range
- typically more computationally intensive than other approaches
In the gray-box battery simulation approach, which is typically implemented in the form of an equivalent electrical circuit diagram, only some of the model parameters have a physical meaning.
- high computing speed
- does not allow any insights into the battery system
- only describes the strongly non-linear battery behavior at a certain operating point rather than across the battery’s entire operating range (SOH, SOC, current, temperature)
In the black-box approach, the battery simulation requires virtually no information about the system to be modeled. Instead, relatively comprehensive and time-consuming measurements in the laboratory are required for parameterization to obtain good simulation results.
These models are currently used relatively rarely in battery simulation.
- high computing speed
- does not allow any insights into the system, preventing a more in-depth understanding of the battery
