EV experts from Southern Company and Argonne National Laboratory will share insights on recent developments and obstacles on defining required resources for informed planners of medium-duty and heavy-duty electric vehicle charging infrastructure. In-depth technical issues will be covered, with emphasis on minimizing charging location footprint of equipment for charging systems from 100kW to 1MW and above installations. Consequences of managed vs unmanaged charging networks will be addressed that directly impact capital equipment and operating costs.
