Overcoming Electric Vehicle Design Challenges with SaberRD
Introduction: Addressing Electric Vehicle Design Challenges
Designing electric vehicles (EVs) comes with unique challenges, from optimizing battery performance to ensuring efficient power distribution. However, most of these hurdles can be overcome with the right tools and technologies, paving the way for a more sustainable future. In partnership with Synopsys, EDS Technologies offers SaberRD, which addresses some specific design challenges EV manufacturers face. In this blog, we will discuss some challenges and explore key features that can address these challenges.
The Complexities of Electric Vehicle Design
Designing electric vehicles brings new challenges compared to traditional combustion-engine vehicles. The complexities lie in the powertrain and battery systems and other crucial components such as motor controllers, sensors, and charging infrastructure.
Driving Range
One of the primary concerns in EV design is range anxiety. EV manufacturers strive to extend the range of their vehicles to alleviate customer concerns about running out of power. Achieving a balance between range, battery size, and weight is a delicate task that requires advanced modellingand simulation tools.
Charging infrastructure
In the future, we expect improved charging infrastructure and faster chargers to make electric vehicles (EVs) competitive with gas cars. Long-distance travel poses a challenge due to sparse charging stations along routes. While expanding this infrastructure requires significant investment, daily recharging in home garages, workplaces, and commercial areas could eliminate the need for regular stops at filling stations for EV drivers.
Reliability
Ensuring the reliability of powertrain elements like the battery, motor, and power electronics while in use poses a significant challenge for engineers in powertrain design. These components are susceptible to various environmental stressors, including temperature fluctuations and mechanical impacts. Designers of automotive power ICs prioritize meticulous design and manufacturing of integrated power devices. The effectiveness of thermal management systems is crucial in ensuring the efficient and dependable operation of e-powertrain components. Suppliers and original equipment manufacturers (OEMs) must carefully consider material properties and the non-uniform distribution of current, voltage, magnetic flux, and component temperature. The performance of a single component can significantly affect the distribution of flux in others.
