DC as a Service Approach to High Power Commercial Vehicle Charging Systems
The IEEE P2030.13 draft standard (https://standards.ieee.org/project/2030_13.html ) “Guide for Electric Transportation Fast Charging Station Management System Functional Specification” continues the P2030 series of P2030.8 on AC microgrids, P2030.10 on DC microgrids and P2030.11 on DERMS. Pilot fleets of Class 3-Class 8 electric trucks have been deployed with new charging coupler standards aimed at 1500vdc/3000Adc to enable megawatt level power transfer. Power systems, specifically utility interconnections and site specific storage/active load management will be challenged to supply multiple vehicles charging collectively at greater than 1MW. This presentation will cover issues, standards, challenges and gap on designing EV charging systems for many vehicles charging at depot or other locations that require MW+ power levels. The DC-as-a-Service business case will be covered as well as current work on IEEE/SAE standards supporting these types of charging installations.
Theodore Bohn, Argonne National Laboratory
Mr. Bohn is with the Center for Transportation Research at Argonne National Laboratory, which is near Chicago IL. He is a principal electrical engineer in the EV-Smart Grid Interoperability Center, identifying and validating interoperability issues related to PEV charging systems. He actively serves on SAE, IEEE, and EV charging standards committees, including safety standards. His current area of focus is on high power (megawatt level) multi-port charging systems with integrated storage and active load management for DC distribution topologies. He leads US National working group for Weights and Measures related to commercial dispensing of electricity as a fuel. Mr. Bohn received his BS and MS degree in electrical engineering at the University of Wisconsin-Madison. He holds an adjunct faculty position at University of Wisconsin-Madison where he has developed and delivered EV charging safety related education and training materials.
