The Megger EVT100x is a specialized testing instrument designed for professionals who manufacture, service, or maintain electric vehicles (EVs) and hybrid electric vehicles (HEVs). Engineered to support compliance with UNECE R100 safety regulations, the EVT100 provides a complete set of electrical tests in a single compact handheld device.

With its versatile functionality, the EVT100 enables technicians and engineers to perform essential electrical safety and performance tests required in modern EV testing environments.

Comprehensive EV Testing Capabilities

The EVT100 combines multiple essential diagnostic functions in one device, allowing users to perform routine electric vehicle electrical tests quickly and reliably.

Key testing features include:

• Insulation resistance testing up to 1 kV, ensuring high‑voltage system safety
• Low‑resistance bond testing with two‑wire, three‑wire, and four‑wire measurement options
• Continuity and diode testing for circuit verification
• DC voltage measurement with polarity detection

These capabilities make the EVT100 ideal for verifying high‑voltage EV components, grounding connections, and electrical system integrity.

Easy‑to‑Use and Safe Operation

Despite its advanced capabilities, the EVT100 is designed with simplicity and safety in mind. Its intuitive interface allows technicians with limited electrical testing experience to operate the device confidently.

Integrated safety features prevent testing if the instrument is incorrectly connected or used outside its operational limits, reducing the risk of user error. Users also benefit from Megger’s global technical support and detailed application guidance, ensuring reliable and accurate test procedures.

Accurate Results with Advanced Measurement Technology

To guarantee dependable measurements, the EVT100 supports two‑, three‑, and four‑wire low‑resistance testing, which is particularly useful for verifying bonding between metallic components in EV systems.

The insulation resistance testing function includes automatic temperature compensation to maintain measurement accuracy. In addition, a guard terminal eliminates surface leakage effects that could otherwise produce inaccurate readings.

Efficient Data Storage and Reporting

For improved workflow and documentation, the EVT100 includes internal memory capable of storing up to 256 test results. Test data can be easily transferred to a computer via a standard USB memory stick, allowing technicians to generate reports, certificates, and compliance documentation quickly.

This digital reporting capability not only saves time but also minimizes the risk of manual data entry errors.

Durable Design for Workshop Environments

Built with rugged industrial construction, the EVT100 is designed to withstand demanding workshop conditions. Its durable design ensures long-term reliability, making it a dependable solution for EV diagnostics, manufacturing verification, and maintenance testing.

Overall, the EVT100 provides a comprehensive, reliable, and easy‑to‑use testing solution for electric vehicle components and systems.

Connected EV Testing with CertSuite Asset (EVT100X)

The EVT100X expands the capabilities of the EVT100 by adding Bluetooth Low Energy (BLE) connectivity, enabling seamless integration with CertSuite Asset on mobile devices or web browsers.

This connected workflow allows test results to be streamed in real time and linked directly to specific vehicles, components, or test stages, improving traceability and documentation.

Key benefits of EVT100X connectivity:

• Live streaming of test results during EV testing
• Store results against vehicles, components, or assemblies
• Maintain clear and traceable compliance records
• Access test data through the CertSuite mobile app or web platform
• Secure wireless Bluetooth communication

This system helps organizations maintain auditable EV testing records and supports compliance with UNECE R100 requirements and internal quality procedures.

The EVT100X can still operate as a fully standalone testing instrument, while CertSuite Asset adds a digital layer for organizations that require enhanced reporting, traceability, and workflow efficiency.

CertSuite Asset Licensing

The CertSuite Asset Lite version is included at no additional cost. Organizations that require cloud storage and multi‑user account access can upgrade to the full version.

Note: Bluetooth connectivity and CertSuite Asset integration are available only on the EVT100X model, while the standard EVT100 operates solely as a standalone instrument.
