CHALLENGE The failure rate of electronic devices employed in hybrid and pure electric vehicles are strongly linked to temperature and doubling with every 10ºC rise. The challenge is to identify the optimal configuration that is driven by: low chip-to-coolant thermal conductivity; temperature equality; low pumping pressure and physical size.

SOLUTION - In this study, LUCID motors, California-based electric-vehicle company and battery-pack supplier, developed a design strategy to built an inverter and employed modeFRONTIER to perform channel and manifold optimization in order to minimize pressure and temperature ratio. Moreover pervasive thermal analysis and suspension optimization have been carried out.  

BENEFITS - The optimization method enabled to identify the alternative Inverter optimal designs with efficiency enhanced and failure rates minimizedmodeFRONTIER optimization platftorm allowed to automate the design process, quick optimization setup and execution, and support the decision-making in order to overcome highly constrained design problems.
