As a part of the E-mobility motor testing solutions, battery simulation is a must.

The Motomea e-Motorcycle Motor Dynamometer provides a unique array of testing and simulation capabilities.

A bi-directional regenerative DC power supply, with Four-Quadrant operation, allows achieving accurate battery simulations and testing results:

  • Battery Resistance Model System
  • Battery Charging Simulation
  • Battery Discharging Simulation
 

Battery simulation:

  • Modular scalability in the typical power range from 5 to 500 kW.
  • Modular scalability in the typical current range from ±10 to 1200 A.
  • Voltage ranges (5 to 1000 V) that can be adapted to the specific application.
  • Fast voltage control (typically: 3 ms).
  • Fast current control (typically: 1.3 ms).
  • Fast load transient response (typically: 1.3 ms for a load step of 10% to 90% of output current).
  • High control accuracy (typically 0.1% for current and voltage).
  • Real-time simulation.
  • Protection against short-circuits.
  • Insulation monitoring.
  • Standalone or integrated on the intermediate circuit (DC).
  • Battery simulation can be supplied as a standalone solution, or can be integrated into the test system prior to delivery.
