Auto Industry Suppliers – Effectively Manage Electromagnetic Effects
The Electronic Components in an Automobile
The graphic below shows the huge number of electronic components in a non-electric car. There are even
more in an electric car.
If you are a supplier in this market, overdesigning and hoping to pass a required test is no longer a viable
strategy (and we would argue that it never has been). Today, it is critical that you understand the environment
that your product will be operating in. For example:
• Fully electric power trains and the development of vehicle autonomy increases the need for
> Active electrical components
> Complex interconnected systems
> The use of radio frequency systems
• Both far and near-field sensors require low-noise environments
• Real-time decisions making for safety-critical situations requires high-speed communication and
processing
• Power quality from on-board (powertrain) and off-board (utility grid) required deliberate EMC analysis
Updating A Design Strategy
We have helped hundreds of manufacturers update their strategies and processes to meet current regulatory
demands. We always start with these four questions:
1. Are you proactive or reactive? Have you designed electromagnetic compliance into your process?
2. Are your electromagnetic efforts collaborative? Do mechanical and electrical teams work together?
Do you test the components and the full system? Do you correlate simulations and tests?
3. Can you rapidly adapt to changes? Do test results that indicate the need for a design change cause
severe delays?
4. Do you learn from both wins and losses? Do you capture best practices from all situations?
