Modern vehicle technology is undergoing explosive growth. The main driver of this is the rapid advancements in electronics. The global electric construction and agriculture equipment market size was valued at $3661.3 million in 2022, and is projected to reach $24271.2 million by 2032, growing at a CAGR (compound annual growth rate) of 21.1% from 2023 to 2032.
Due to this exponential technological growth and adoption, construction and agricultural whole vehicle EMC (electromagnetic compatibility) testing is becoming increasingly complex; failing a test is easier than you might think. To ensure a successful EMC test, forward-thinking manufacturers should be aware of any roadblocks that may arise well ahead of time. In this blog, we’ll explain the top five challenges we have encountered most often over our decades of vehicle EMC commercial testing experience, and we will share our expert advice to overcome them.
- Inadequate Chamber Size
The challenge: Most EMC chambers are designed for component testing, not whole vehicle testing. Maintaining proper test distances and field uniformity quickly becomes extremely difficult if testing is being performed in a room that isn’t made to test the entire vehicle.
The solution: Prior to scheduling an EMC test, review the testing chamber size of a potential test provider to make sure your vehicle can comfortably fit inside. For large agricultural equipment like tractors and construction machinery like dump trucks, this is a crucial step.
At Elite, our facility is equipped with a whole vehicle EMC testing chamber featuring 70’ long x 33’ wide x 18’ high room dimensions, 16’ wide x 16’ high door dimensions, and 80,000 lb. weight capacity. We can accommodate large vehicles, such as coaches, buses, combines, sprayers, front-end wheel loaders, large tractors, and bulldozers.
- Extensive EMC Test Setup
The challenge: Whole vehicle EMC testing in a highly extensive process, which requires extensive planning. This includes determining your product market, creating a detailed test plan, finalizing software, and much more.
The solution: Pre-planning is non-negotiable. We detail step-by-step EMC test planning instructions in our ebook, 10 Steps to Successful Automotive EMC Testing. Here are the key takeaways for construction and agriculture industry vehicle manufacturers seeking a streamlined EMC vehicle testing process:
- Know your market. Are you selling to OEMs, or is it an aftermarket product? In which countries will you be selling your product? Different countries have different regulations that you must comply with.
- Develop a test plan that captures all the information the test engineer needs to accurately complete the project. Many OEMs require a test plan approval process, but even if it’s not required for your vehicle, we still strongly recommend creating one. We have found this to be an invaluable tool to build confidence between the vehicle OEM and end user. At Elite, our team of expert engineers is happy to review your test plan to confirm that the necessary signatures and laboratory identification are present.
- Design for compatibility. EMC testing aims to confirm that a device will operate properly in the presence of its own interference as well as from other nearby and connected devices. To get a full picture of what is required of your vehicle, learn all of the corporate EMC standards or regulatory requirements for your vehicle’s parts and include them in the test plan.
- Perform development testing prior to validation testing. This adds confidence to product design and greatly improves the odds for successful validation testing.
- Prioritize communication. Open discussion throughout the testing process builds the relationship between the tester and manufacturer, and improves the potential for a successful EMC test. We also strongly urge communicating your scheduling needs. The earlier you reach out, the more likely you are to keep your timeline on track. Once testing begins, we will deliver daily progress updates. We also ask that clients inform us promptly of any project delays.
- Configure a fully functional system that can be delivered to the test laboratory on the scheduled start date. This will help the test run smoothly.
- Inauthentic Real-World Operating Conditions
The challenge: Whole vehicle EMC testing replicates a number of real-world operating conditions your vehicle is likely to encounter, like climate control active or engine running. Creating a realistic and safe environment while maintaining measurement accuracy, all while your vehicle is enclosed in a test chamber, is a highly involved undertaking.
The solution: Talk with your test engineers to ensure they have all of the proper protocols in place to run vehicles in their testing chambers. This includes ventilation systems, extraction systems, and dynamometers to simulate driving conditions.
- Evolving Standards
The challenge: As we’ve illustrated above, electric construction and agriculture equipment is accelerating fast with no signs of slowing down. Governments are starting to roll out new regulations to keep up compliance standards (see FCC Part 15, for example).
The solution: Check that your prospective testing company is keeping up with all regulations. Elite’s regulatory experts can help you navigate the ever-changing compliance landscape.
- High-Power, High-Voltage Systems
The challenge: Construction and agricultural vehicles pack much more power and battery voltage than the average car. These powerful systems are more likely to introduce significant electromagnetic interference and transients during EMC testing.
The solution: Find a partner with the facility, protocols, and experienced engineers in place to conduct EMC testing for large vehicles. At Elite, we specialize in testing heavy-duty construction and agricultural vehicles.
