inepro Metering’s new devices bring portable on-site accuracy testing to EV charge points

inepro Metering has launched two new portable devices, the Tunkia TE1000 and TE1100, designed to verify the measurement accuracy of electric vehicle (EV) charging points on-site. These compact testers are intended for use by manufacturers, network operators, and inspectors to ensure that EV charging stations are billing customers correctly. The introduction of these devices addresses a significant gap in the industry, as EV charge points currently lack mandatory inspection or recalibration requirements, unlike traditional utility meters such as those for gas and water. The absence of routine accuracy checks means that measurement errors of between 2 and 5 percent can go unnoticed for extended periods, potentially causing substantial financial losses for operators managing large charging networks. Such inaccuracies often manifest as unexplained billing discrepancies, which are frequently misattributed to software or hardware faults rather than the metering equipment itself. The new Tunkia devices offer a practical solution by enabling rapid, on-site verification that combines traceable calibration with automated testing, producing reports that support audits and quality assurance processes. This development is particularly timely given the increasing regulatory scrutiny in Europe, notably the German Eichrecht standard, which mandates transparency and tamper-proof measurement in EV charging. As this regulatory framework is expected to expand across the continent, inepro Metering positions its new testers as a proactive tool for stakeholders to achieve compliance ahead of enforcement deadlines. The devices cater to a broad range of users, from manufacturers conducting design validation to operators performing routine network checks and independent auditors carrying out third-party assessments. inepro Metering brings over three decades of experience in producing kWh meters and original equipment manufacturer (OEM) metering solutions, lending credibility to the new product line. By facilitating more accurate and reliable measurement of EV charging energy, the TE1000 and TE1100 could play a crucial role in enhancing trust and transparency in the rapidly growing electric mobility sector. The availability of such portable verification tools may also encourage wider adoption of standardised testing practices, ultimately benefiting consumers and operators alike.
