Triplett Highlights Need for Field Verification in EV Charging Infrastructure

Triplett, a company with a long history of providing test and measurement instruments, has highlighted the growing need for field verification and troubleshooting in electric vehicle (EV) charging infrastructure. The firm emphasizes the importance of using EVSE testers to ensure reliable performance and efficient maintenance of EV charging stations.

The installation of an EV charging station marks just the beginning of its operational lifecycle. Once in service, technicians must often investigate charging interruptions, verify performance, and determine whether issues stem from the charger or the supporting electrical system. Voltage, current, wiring, connections, grounding, and other electrical conditions can significantly impact charging performance. Some problems may not be evident from visual inspection or the charging station's user interface, necessitating direct evaluation of the installation.

Portable testing equipment allows service personnel to perform diagnostic checks at the charging location, relying on measured conditions rather than visual observations or user-reported symptoms. Consistent testing procedures can facilitate better communication among electricians, commissioning teams, service technicians, and facility managers. Documented results provide a useful record of equipment condition during installation and subsequent service.

Triplett offers the TEV300 Electric Vehicle Charger Test Kit, designed to support installation verification, maintenance, and troubleshooting activities across EV charging applications. The test kit helps technicians evaluate the wiring condition and electrical status of EV charging stations by providing visual LED indications that identify common wiring conditions and charger output socket status. It can also simulate vehicle connection states to support charger verification during commissioning and service activities.

For situations requiring additional electrical measurements, technicians can use a multimeter in conjunction with the test kit to further investigate voltage and other electrical conditions at the charging station. This comprehensive approach ensures reliable and efficient EV charging infrastructure, supporting the growing demand for electric vehicles.

Triplett has supplied professional test and measurement instruments since 1904, offering solutions for electrical testing, thermal imaging, environmental measurement, networking, maintenance, HVAC, security, industrial inspection, and process calibration. The company's products help electricians, contractors, technicians, inspectors, maintenance personnel, and facility managers perform testing, verify equipment and installations, troubleshoot operational issues, and support informed service and maintenance decisions across commercial, industrial, and field environments.
