Grid and Fleet Impact Mapping of EV Charge Opportunities

This chapter assesses the impact of different technical solutions and their impact on the ability of a fleet of plugin hybrid electric vehicles to drive in electric mode as much as possible. The technical solutions covered in this chapter to attain this objective include: charging at low and medium power; charging at home, at work and at other locations and using fleets with small, medium and large battery sizes. The driving behavior of the fleet is modeled using an availability analysis based on statistical data from Flanders and the Netherlands. The fleet itself is based on data of the Flemish vehicle segmentation, while the electric consumption of each segment is determined based on realistic vehicle data and driving cycles. This data is combined into different scenarios for which the utility factor, the energy consumption, the grid impact and the battery utilization is investigated. Based on these scenario guidelines concerning the appropriate charge power at different locations, the distribution of charge locations, the expected grid impact and utility factor of different fleets are formulated.status: publishe
