BRISTOL, PA — With electric vehicle (EV) adoption accelerating, the reliability and accuracy of charging infrastructure have become critical to sustaining growth in this sector. While the U.S. boasts over 71,000 public EV charging stations with approximately 200,000 ports, and Canada features 12,955 stations with 33,767 ports, widespread concerns remain regarding charger functionality and energy billing accuracy.
Recent studies revealed that 26% of public charging stations in the U.S. fail to perform as expected, and up to 45% of DC fast chargers experience functionality issues. Further, California estimates that over 15% of public chargers inaccurately bill customers, raising concerns about regulatory compliance and consumer trust. These challenges underscore the pressing need for standardized testing to ensure fair pricing and billing transparency.
Fair billing is essential for both consumers and operators. Overbilling can deter EV adoption by eroding trust, while underbilling impacts operator revenue and threatens the financial viability of charging networks. Without reliable metering systems, the growth of EV infrastructure faces substantial risks.
