EV Cooling Sample System Model






Motor Thermal Design and System Level Integration; Simcenter Flomaster & Simcenter Motorsolve

              • Ensuring the cooling systems of electric vehicles are properly designed is critical to ensuring thermal reliability, minimizing cost, and maximizing vehicle drive range.
              • Siemens automated thermal characterization is ideal for system engineers to account for thermal issues from earliest prototyping stages and reducing overall design cycle.



Thermal-driven implications for electric powertrain cooling system performance.


  • Accurate estimation of thermal behavior for motors over a range of driving conditions allow thermal system engineers to optimize cooling component sizing (and therefore cost) without jeopardizing motor  and power inverter life, due to high temperatures in the automotive environment.
