From whence are these chargers charged? 

 

 

I would assume from the grid. By having a battery acting as a 'reservoir' it avoids the requirement for a supply cable to the facility capable of delivering the full 180kW supply. By the sounds of this the grid supply is good for 120kW with the battery being able to boost that to 180kW.

 

It lelays that upgrade capex, but probably doesn't totally remove the need for it... As the number of Vehicles using the charger rises, the battery recharge time available between uses will shrink...

But because the demand is established and there is data on the growth rate of the number of users, its much easier to justify to the accountants to upgrade the feed connections... at which point you can take the battery set up off to another "fringe" location at look at boosting use there...

Its a great way to get round the "Chicken and Egg" problem, - especially as lines companies like Counties energy have regulated Capex as they are a local monopoly and are restricted from "over building"
