Expanding Capacity, Enhancing Accuracy: NMi Invests in New EMOB500 for On-Site DC Charger Testing
01 July 2025
Bringing precision and performance to EV charging station verification—wherever you need us.
As the global roll-out of electric vehicle (EV) infrastructure accelerates, the demand for accurate, on-site verification of DC fast charging stations is growing fast. At NMi, we’re meeting that
demand head-on—with a significant new investment in our mobile testing capabilities.
We’re proud to announce the addition of the EMOB500, developed by ZERA (Germany), to our fleet of high-performance portable test equipment. Purpose-built for DC energy metering and charger performance testing, this new system strengthens our ability to support manufacturers, integrators, and regulators—both across Europe and around the world.
What the EMOB500 Brings to the Field
The EMOB500 enables our engineers to carry out high-accuracy, on-site measurements at charging stations operating up to:
- 500 A DC current,
- 1,000 V DC voltage.
Its integrated reference meter allows us to compare measured output from the charging station with a trusted benchmark under real-world conditions. This is essential for verifying charger accuracy across a variety of load profiles and use scenarios.
Designed for Mobility, Built for Precision
What makes the EMOB500 especially well-suited to our fieldwork is its:
- Compact, rugged design housed in a dedicated transport case
- Rapid setup enabled by a CCS output cable for fast and secure connections
- Versatility, allowing us to adapt quickly to different station types and testing environments
This makes it ideal for on-site investigations at client facilities, type testing for manufacturers, or validation at deployment locations.
A Step Forward for Global Testing Services
With demand for mobile DC charging station assessments growing—particularly from global clients—this investment directly expands our capacity to:
- Deliver rapid, accurate testing across regions,
- Support international standards and regulatory needs,
- And provide trusted, third-party verification wherever needed.
Whether you’re launching a new charger model or verifying existing installations, we now bring even more advanced tools directly to your site.
Our Commitment to Innovation in EV Testing
At NMi, we’re continuously investing in tools, knowledge, and partnerships that help our clients move confidently through compliance, certification, and product optimisation. The EMOB500 enhances not just our capability—but your confidence.
