Electric Vehicles Modeling & Simulation

Get to Market Faster & Optimize Your Electric Vehicle Designs

To be competitive in designing and manufacturing electric vehicles (EV) in today’s environment, you cannot afford to make design mistakes that extend your time to market, increase costs, and reduce the safety for end consumers.

Using simulation and modeling techniques will reduce the costs associated with prototyping, allow you to get to market faster by solving design issues yet to be defined, and increase quality and safety.

  • Use Simulation Early in the Design to Prevent Problems Before They Begin
  • Test Your Design Ideas Without Prototyping
  • Be Smart – Simulate

Benefits We Provide

Working with virtual modeling and simulation of fluid flows allows you to accelerate your design process using software such as Star-CCM+ or OpenFOAM. This reduces the number of physical prototypes and testing, while still evaluating all necessary conditions. Our engagement ranges from CFD consulting, to training, to customized workflows that meet your specific needs. 

Our simulations help save you time and money while providing valuable insights. Working with TotalSim will put you years ahead of the competition, while simultaneously lowering your costs and optimizing your designs. Let us help you reach your goals efficiently and accurately.

Our Success Stories

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.

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.

Drag Improvement
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.

Motor design
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.

Battery Cooling
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.

ADAS Sensors
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.

Outperform the competition by taking advantage of our extensive CFD experience today.
