Battery systems operating with the utmost performance are what makes electrical systems in e.g. electrified vehicles, ships, and aerospace applications efficient. Physically correct simulation decisively drives the development of batteries and battery management systems.
The tool is suitable to be used in safety-related development projects according to ISO 26262:2018 for any automotive safety integrity level (ASIL).
The tried-and-tested ASM multicell battery model assists you in the early phases of controller development and in the validation of control units. 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.
The ASM battery model simulates the voltage behavior of a battery based on an equivalent system with two RC-elements as default. If required, everything is prepared to be extended with further RC-elements. The battery pack respects cell-wise balancing currents and can handle each cell temperature, while simulating the voltage behavior of the battery.
As battery pack topologies vary from application to application, the ASM battery model follows a flexible approach. An ASM battery system can be formed with a parallel connection of battery packs which contains a flexible number of series connections of battery stacks where each stack represents a parallel connection of battery cells. Whether or not a clustering of modules is respected, depends on the architecture of so-called cell-supervision-circuits.
In order to provide a comprehensive ready-to-use demo, the model is equipped with a BMS SoftECU. The SoftECU is able to control the pre-charge circuit switches, perform passive cell balancing while charging and estimating the state-of-charge, and monitor the battery during operation. Our open ECU interfaces are already contained inside our demo model.
Of course, the real-time capability of the demo is ensured for today's battery systems and especially the compatibility with dSPACE BMS HIL systems is guaranteed. 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.
Less demanding applications, such as the simulation of vehicle power networks, are supported by a dedicated battery model.
