Model Features
The ASM battery model simulates the voltage behavior of a battery using an equivalent system with two RC-elements, which can be expanded as required. The battery pack respects cell-wise balancing currents and can handle each cell temperature, while simulating the voltage behavior of the battery. The model structure is flexible and allows different battery topologies: A system can consist of battery packs connected in parallel, which in turn contain stacks in series - each stack represents a parallel connection of cells. The consideration of module clustering depends on the architecture of so-called cell-supervision-circuits.
An integrated BMS SoftECU can control the pre-charge circuit switches, perform passive cell balancing while charging and estimating the state-of-charge, and monitor the battery during operation. Open ECU interfaces are already included in the demo model.The demo can easily be scaled with further ASM components, i.e., electric motor, fuel cell, vehicle or even truck simulation, as the collaboration within the ASM product family is one of our major goals.
Application Areas
You can use it to complete component tests or simulate the performance of a battery system in any type of application. It performs on SIL and HIL platforms, so that frontloading of tests or preparation of the test setup can be shifted to the early project phases.
Characteristics
Experience a powerful and versatile battery pack model designed to simulate complex cell clusters with ease. Thanks to its serial circuit foundation and parallel extendibility, it delivers precise terminal voltage calculations while accounting for ohmic losses and capturing the full dynamic behavior of your system. Each cell’s state of charge is calculated individually, with balancing currents respected to ensure accuracy and realism.
A sophisticated thermal model adds another layer of fidelity, simulating the temperature of every single cell. Whether you’re working with Pb, NiCd, NiMH, or Li-Ion technologies, flexible parameterization makes this solution adaptable to your needs. The model also integrates seamlessly with the electrical periphery, including pre‑charge circuits, DC links, and charging stations.
To accelerate your projects, a ready‑to‑use demo featuring the BMS SoftECU is included. From intuitive coupling with ASM charging stations to direct support of dSPACE smart charging and cell voltage emulation hardware (BMS HIL), the system is built for smooth integration. And for less demanding applications, such as simulating vehicle power networks, a dedicated battery model ensures efficiency without compromise.
