Why V2G is gaining momentum (6) – V2G Costs

A major impediment for V2G has mainly been the high cost of infrastructure

The good news: costs* are coming down fast

1.    Infrastructure

V2G DC chargers have decreased in price from ~$8,000+ to $2,500 (7.4 kW); V2G AC chargers (10kW-20kW) around $1,000

2.    Energy loss

First V2G chargers could have a two-way energy loss of 30% – 40%. New V2G chargers around 5%-10%

3.    Battery wear

Fear of extensive V2G battery wear is greatly exaggerated. Nuvve, Nissan and Enel have deployed a V2G solution in Denmark since Sep. 2016 and have logged 250,000+ hours of operation with little V2G battery wear. The largest wear is from ageing, driving and fast charging. Nissan is so confident that it warrants their batteries for V2G (conditions apply)

4.    Energy (net metering)

For grid services the imported energy include taxes and fees, whereas the exported energy only is paid typically at the electricity cost. This issue still needs to be resolved in many regions to bring the cost of energy down

5.    BRP/Scheduling coordinator

For grid services a BRP (Europe)/Scheduling Coordinator (US) must be involved, adding cost. With V2G volume this cost should decrease substantially per aggregated EV
