Clearly, if there were more customers, the cost per session would fall. But because current costs are so high, investors have been slow to build stations, and because there are not enough charging stations, consumers have been slow to buy BEVs. There is a way to resolve this conundrum: stationary battery storage (Exhibit 3).
