MTE (Meter Test Equipment Inc)

Exhibitor

MTE Meter Test Equipment (MTE) manufactures high-precision AC/DC calibration and testing systems designed to verify Electric Vehicle Supply Equipment (EVSE) - Level 2 AC and DCFC/Level 3 EV chargers. Our solutions ensure commercial EV chargers are safe, highly accurate, and legally compliant for consumer billing in both field and laboratory settings.

Key EVSE Test and Calibration Offerings

• Portable EVSE Working Standards & Adapters: MTE offers specialized measurement equipment, such as the eMOB I-500.1 AC/DC) that interface directly between the charger and the vehicle. These simulate EV charging states and accurately measure energy (kWh) at the transfer point to test against high-precision Portable Working Standards (PWS 3.3 genX)
• DC Meter Calibration Systems: MTE provides systems like the SRS 121.1 DC, which is a multi-channel reference standard for verifying multiple DC Energy Measuring Units (EMUs) or electricity meters simultaneously at high accuracy classes (e.g., Cl. 0.04)
• Stationary Test Systems: For labs and OEMs, MTE builds modular AC and DC power sources capable of performing phantom load tests. These cover legal metrology requirements for EVSE measurement systems, handling up to 1,500 V DC and 1,500 A DC
• CALegration Software: MTE pairs its hardware with this dedicated documentation and report generator, which handles data readout, manages calibration processes, and automatically generates compliance reports.

Why MTE Equipment Stands Out

• Precision: MTE's equipment features top-tier accuracy (reaching as precise as 0.05% or better), which is crucial for modern smart meters and legal-for-trade billing
• Broad Compatibility: Their testing devices support both AC (PWS 3.3 genX + PPL150 (portable power load)) and DC (eMOB I-500.1 AC/DC) charging standards, including SAE J1772, CCS, and NACS plugs.
• Field-Ready Durability: Despite laboratory-level accuracy, MTE's portable equipment is lightweight, ruggedized, and designed for technicians to perform rapid on-site calibration
