44KW at 240V is about 185 amps (likely more because of conversion losses and voltage drop). That makes for very large wire. Jim Walls

Doesn't that just defer the cost to installation? Seems like you would need bigger wires using half the voltage.

I do know that it is entirely developed in-house incl production/assembly and the concept they are using is quite innovative, this is the first Smart Grid enabled Fast Charger, so they can integrate it into their network and you can earn money with it (JuicePoints is one of their programs). This means that the charger can earn back its investment if it is used often enough. > The cool thing with this Fast Charger is that it only requires a standard single phase 208 or 240V connection which is way cheaper and easier to find than the 480 Delta connections that almost all other Fast Chargers require, as 480V is the standard for a business park service connection but it is hard to find that voltage elsewhere. > There is some other amazing feature of this Fast Charger that I rather see > that they disclose themselves, so I won't post it on here. > They are still in the final stages of the basic development, working on things such as the cooling.
