Total Vehicle Review
Managing the balance between styling and performance is a challenge we often face and this was no different for a recent limited production, hybrid supercar development. We improved the cooling while preserving the radical styling, reduced drag and improved handling, and solved hot exhaust impingement issue.
We completed a parametric study of a new starter design for an electric drive motor as well as identified methods of reducing weight and volume in motor design while increasing torque density. Our team also assessed effect of part thickness and materials of construction on the performance of the motor.
We developed simulations of design concepts for advanced driver assistance systems. In one project, we assessed the effect of solar heating on the optical performance of sensors used for three-dimensional awareness of vehicle’s surroundings. In a second project, we assessed approaches for enclosing piezoelectric ultrasonic sensors behind the vehicle body.
Our team assessed the role of phase change materials in the thermal management of electric vehicle batteries. We also assessed the performance of an indirect liquid cooling system that circulates liquid coolant through pipes embedded in the battery. Finally, we reviewed design layouts to determine a design that provided the most uniform temperature within the batteries.
It is beneficial to incorporate simulation and modeling early in a design process; however, for various reasons that doesn’t always happen. With deadlines looming, we rapidly turned around over 25 cases in the first five days of working with an EV motorcycle manufacturer resulting in a substantial drag improvement while preserving the design styling.
Heat and Cooling System
Baseline CFD analysis of the main heat exchanger and cooling system for a medium duty EV truck showed that there were inefficiencies in the design. After discussing the root problem with the client, we quickly delivered a solution that increased the heat exchanger cooling capacity by over 65% as well as recommended avenues for improvement to reduce overall vehicle drag.
