Triplett pushes EV charger field testing as infrastructure expands

Triplett Test Equipment & Tools is spotlighting the need for on-site verification and troubleshooting as EV charging stations spread across workplaces, fleets, commercial properties and public locations. The company says portable testers can help technicians separate charger faults from electrical-system problems and document equipment performance over time.

Why it matters: - EV charging stations are moving from one-time installations to ongoing service assets that need verification, maintenance and troubleshooting. - Electrical professionals need faster ways to tell whether a charging problem comes from the charger itself or from the supporting electrical system. - Better field testing can reduce downtime at commercial, workplace, fleet and public charging sites.

What happened: - Triplett Test Equipment & Tools highlighted the growing need for field verification and troubleshooting across EV charging infrastructure. - The company said electrical professionals are taking on a larger role in keeping charging equipment operational after installation. - The emphasis covers charging sites in commercial properties, workplaces, fleet facilities and public locations. - Triplett pointed to its EV Charging Station Testers as tools for installation verification, maintenance and troubleshooting.

The details: - The company said an EV charging station’s installation is only one stage of its operating lifecycle. - Technicians may need to investigate charging interruptions, verify performance or determine whether a problem is in the charger or the electrical installation supporting it. - Voltage, current, wiring, connections, grounding and other electrical conditions can affect charging performance. - Some problems may not show up in a visual inspection or on the charging station’s user interface. - Measurements at the charging location can help narrow the source of a problem by showing the electrical conditions present during testing. - Commissioning measurements can establish a baseline for newly installed equipment. - Keeping those results gives service teams a reference point for future changes in charging performance. - Richard Wexler, vice president of global business development at Triplett Test Equipment & Tools, said the first question during a service call is often whether the problem is inside the charger or in the electrical system supporting it. - Wexler said on-site measurements give technicians evidence to narrow that question before deciding what needs repair, adjustment or replacement. - Portable testing equipment lets service personnel perform diagnostic checks at the charging location and work from measured conditions instead of relying only on visual observations or user reports. - Consistent testing procedures can make it easier for electricians, commissioning teams, service technicians and facility managers to compare findings. - Documented results can provide a record of equipment condition during installation and later service. - The TEV300 Electric Vehicle Charger Test Kit provides visual LED indications that identify common wiring conditions and charger output socket status. - The TEV300 can also simulate vehicle connection states to support charger verification during commissioning and service. - When more electrical measurements are needed, technicians can use a multimeter with the test kit to investigate voltage and other conditions at the charging station. - More information is available at Triplett’s EVSE testers page.

Between the lines: - As EV charging networks spread, service work is shifting closer to the field and farther from a simple install-and-forget model. - The push for measured, documented testing reflects a broader need for reliability across distributed charging sites. - Triplett is positioning its tools around that service workflow, not just initial installation checks.

What's next: - As charging infrastructure expands, technicians are likely to rely more on portable verification tools during commissioning and field service. - Documented test results should become more important for maintenance records and troubleshooting across multi-site charging networks. - Triplett is likely to continue emphasizing tools that help electricians and service teams validate EV charging performance on site.

The bottom line: - EV charging uptime depends on field verification as much as installation, and Triplett is betting technicians will need better tools to prove where a fault starts and ends.
