HighlightsDynamic charging can extend driving range at lower cost than increasing battery size.Annual dynamic charging can be more economical than gasoline refueling at $2.50 per gallon.A 40kW dynamic charging system is estimated to cost $2.5 billion in California.240 miles of electrified roadway would be required for EVs charging at 100kW.

    AbstractThis research evaluated the potential for wireless dynamic charging (charging while moving) to address range and recharge issues of modern electric vehicles by considering travel to regional destinations in California. A 200-mile electric vehicle with a real range of 160miles plus 40miles reserve was assumed to be used by consumers in concert with static and dynamic charging as a strict substitute for gasoline vehicle travel. Different combinations of wireless charging power (20–120kW) and vehicle range (100–300miles) were evaluated. One of the results highlighted in the research indicated that travel between popular destinations could be accomplished with a 200-mile EV and a 40kW dynamic wireless charging system at a cost of about $2.5billion. System cost for a 200-mile EV could be reduced to less than $1billion if wireless vehicle charging power levels were increased to 100kW or greater. For vehicles consuming 138kWh of dynamic energy per year on a 40kW dynamic system, the capital cost of $2.5billion plus yearly energy costs could be recouped over a 20-year period at an average cost to each vehicle owner of $512 per year at a volume of 300,000 vehicles or $168 per year at a volume of 1,000,000 vehicles. Cost comparisons of dynamic charging, increased battery capacity, and gasoline refueling were presented. Dynamic charging, coupled with strategic wayside static charging, was shown to be more cost effective to the consumer over a 10-year period than gasoline refueling at $2.50 or $4.00 per gallon. Notably, even at very low battery prices of $100 per kWh, the research showed that dynamic charging can be a more cost effective approach to extending range than increasing battery capacity.
