Fluke’s FEV500 acts as a virtual EV to test DC fast chargers, replacing three separate instruments

Fluke has introduced the FEV500, an innovative all-in-one testing device designed specifically for Level 3 DC fast charging stations. This new tool acts as a virtual electric vehicle, enabling technicians to perform comprehensive safety, communication, and interoperability tests without the need to bring an actual EV to the charging site. The development responds to a significant industry challenge highlighted by a Harvard Business School study, which found that around 20% of DC fast chargers in the US are not operational, underscoring the need for more effective testing solutions. The FEV500 addresses the complexity of DC fast charger testing, which goes beyond simple electrical checks by requiring a digital handshake between the charger and the vehicle before charging can commence. Supporting key international standards ISO 15118 and DIN SPEC 70121, the device validates the full communication protocol stack, ensuring that chargers meet stringent interoperability requirements. By integrating the functions of a digital multimeter, insulation tester, and oscilloscope into a single unit, the FEV500 simplifies the testing process, eliminating the need for multiple instruments and reducing setup time. Designed with field technicians in mind, the FEV500 features guided workflows and automated test sequences that deliver clear PASS/FAIL results, making it accessible even to those without advanced technical training. It also logs test data directly to the device, supporting commissioning, maintenance, and troubleshooting from one interface. The rugged chassis, complete with wheels and a removable battery, is tailored for mobility between sites and convenient air travel, reflecting the practical demands of fieldwork in the EV charging infrastructure sector. Theo Brillhart, Fluke’s Technology Director, emphasised the critical role of reliable fast DC charging in the broader electric vehicle transition, noting that current reliability issues remain a significant barrier. The FEV500 aims to bridge this gap by providing a robust, user-friendly solution that enhances the operational readiness of DC fast chargers. Now available on the market, this device represents a key step forward in ensuring the dependability and efficiency of EV charging networks.
