摘要：

This document addresses the challenges in power/energy measurement for commercial dispensing of electricity as a fuel, using a scalable submeter designed to support a spectrum of charging system sizes and technologies. Certified accuracy measurement of delivered charging energy is required by nationwide, state enforced, weights and measures regulations for commercial EV charging transactions. Electric vehicle charging power is limited by available electrical distribution system infrastructure capacity and the rating or size of the electric vehicle battery system. A scalable submeter design can support light duty 3kW AC charging up to (work in progress) class 8 heavy duty electric vehicles delivering up to 1500vdc, 3000adc (4.5MW max). In simple terms, scalable from 120v to 1500v and with proper sensors from 30A to 3000A using the same submeter.
