Toolbox Speichersysteme

Designing, Simulating and Testing Electrical Energy Storage Systems

Developers can use the Toolbox Speichersysteme simulation environment for many different battery simulation tasks conveniently via a graphical user interface.

Toolbox Speichersysteme (”Energy Storage Toolbox”) is a new development environment for simulating electrical energy storage systems. This new environment, developed by dSPACE and the Institute for Power Electronics and Electrical Drives (ISEA) of RWTH Aachen supports a particularly broad range of physical battery characteristics. Toolbox Speichersysteme makes it possible to realistically simulate the electrical and thermal behavior of various batteries, supercapacitors and other electrical energy storage systems, depending on their design and cooling system. The intuitive graphical user interface lets users conveniently configure and parameterize the virtual energy storage systems.


Flexible Parameterization
For the lithium-ion battery technology, which is critically important for electromobility, the simulation environment gives developers many different configuration options. These options include various aspects such as battery technology, the geometric shape of a battery, the number and arrangement of storage cells, wiring topologies or the peripheral cooling system. The simulation model uses these configuration settings to calculate the thermal and electrical behavior of a defined battery at cell level and system level and simulates thermal effects with a high local resolution. Developers can therefore analyze the cooling strategy and identify potential hot spots that would occur during battery operation.


Efficient Development Process
Toolbox Speichersysteme aims at using the model-based development process for energy storage and battery management systems (BMS). Such processes are used in the automotive sector for electric drive systems and electrified drivetrains, among others. The new simulation environment supports the complete process, from the virtual design of a battery, to in-vehicle simulation, to testing the BMS ECU. The simulation model can be configured via parameterization. For example, the battery topology, the battery’s geometric shape, the electrical characteristics, and the level of detail can be defined via parameters and used immediately in the simulation. The simulation model can be used in traction applications and also in other areas, such as energy supply and industrial and housing technology.


Seamless Tool Chain
Toolbox Speichersysteme is integrated into the dSPACE tool chain so batteries can be simulated either offline on a PC platform or in real time together with a battery management system ECU on a hardware-in-the-loop (HIL) simulator. Basic functions such as automation and data management are supported. This enables a seamless development process from battery system design to ECU testing. Toolbox Speichersysteme was already validated in an industrial project and is now available as a proven solution solution for development projects.

Toolbox Speichersysteme was created as part of a research project funded by the European Union and the German Federal State of North Rhine-Westphalia.

In Brief

  • Development environment for simulating electrical and thermal properties of various storage systems
  • Emulation of storage packs consisting of hundreds of cells in real time with a high local resolution of the temperature behavior
  • Simplified battery design process by virtualizing everything from system design to battery management
