Electrical Vehicles for Transportation


The increasing volume of traffic, especially in the city and the need to reduce CO2 emission is today the primary reason to promote public transportation. Electric buses, subways and trains contribute to less city traffic, reduce emissions, and drive with renewable energy independent of fossil fuels. DEWETRON offers the right solution for online power measurements, efficiency calculation and for analyzing mechanical parameters.

POWER ANALYZER 


DEWETRON’s distributed and synchronized solutions makes it easy to test electric trains and buses in real driving applications and on a test bench. Even for testing electrical trains or electrical buses with several traction motors DEWETRON offers the right solution for online power, efficiency calculation and for analyzing mechanical parameters like torque, rotation speed, vibration or environmental parameters such as temperature even for wide spread measurement points. High sample rates, broadband filters, high performance power calculation and additional inputs for CAN and counter turn the DEWETRON solution to the right tool for testing electrical vehicles.


TYPICAL DEWETRON SOLUTION 

  • 9 TRIONet Distributed systems
  • 4 TRION-1820-POWER-4
  • 16 TRION-POWER-SUB-dLV-5V
  • 4 TRION-1603-LV
