Battery Emulator for Electric Propulsion Systems

In modern powertrain configurations such as hybrid vehicles, pure electric vehicles or fuel cell powered vehicles, electric motors and their power electronics play a central role. The AVL E-STORAGE BE is the perfect tool to characterize and verify e-motors and inverters.

Thanks to its unique control strategy for outstanding control accuracy and stability, the AVL E-STORAGE BE™ enables the most realistic emulation of a real-world battery. Automated configuration changes in the Power Distribution Switch Box (PDSB) reduce the testbed downtime and result in a higher testbed use. The PDSB allows you to switch between testbeds and/or the parallelization of systems.
The integrated web-GUI interface provides remote system parametrization and smart service capabilities. To be compliant with latest test runs, the AVL PUMA Open 2™ testbed automation platform facilitates the recording of reproducible measurement data across the entire development process.

Key Benefits

  • Unique control strategy enables realistic battery emulation with outstanding control accuracy and stability
  • High system versatility with automated configuration changes reduces testbed downtime
