BRISTOL, PA — With the rapid expansion of electric vehicle (EV) adoption, the reliability and accuracy of charging infrastructure have come under scrutiny. The U.S. currently boasts over 71,000 public charging stations housing approximately 200,000 ports, while Canada supports 33,767 ports across 12,955 stations. Yet, concerns over charger reliability and billing accuracy persist, posing risks to the industry’s growth.
Research reveals that 26% of public EV chargers fail to function as expected, while up to 45% of DC fast chargers have been reported as nonfunctional or broken, leading to failed sessions and billing issues. Additionally, California estimates over 15% of public chargers inaccurately bill customers. Despite regulatory standards like NIST Handbook 44, many chargers remain uncertified, exposing both consumers and operators to financial and regulatory risks.
“Accurate energy measurement is not just a regulatory requirement but a cornerstone of consumer confidence,” says TESCO (The Eastern Specialty Company), a leader in metering accuracy since 1904. Their patented Electric Vehicle Supply Equipment (EVSE) testing solutions address these challenges with precision.
TESCO’s technologies include:
- Comprehensive Accuracy Verification, ensuring energy dispensed matches what’s billed.
- Real-World Simulation, replicating actual charging conditions.
- Portable Testing Tools, enabling on-site testing and reducing downtime.
Reliable and accurate charging infrastructure is critical to fostering trust among EV users and ensuring the financial sustainability of charging networks. TESCO remains dedicated to supporting utilities, operators, and regulatory bodies by providing advanced solutions to strengthen the EV ecosystem.
