It really baffles me how much an L3 station costs. What about making it simple, here is a thought: Create a battery bank using cheap deep-cycle batteries that can provide 20+kW of power and 400v DC.
First, we are not talking about L3, we are talking about CHAdeMO, also known as DCQC. "L3" is a term coined by the SAE and even their combo plug (aka Frankenplug) is not an L3 by their definition. They propose future AC L3s and DC L3s.
Second, you don't seem to understand what a DCQC must do. It does not provide a constant 400v input to the car. It provides a
variable voltage at high amperage. The battery controller inside the car constantly tells the DCQC through the CHAdeMO interface what voltage it must provide at that point in time. It is by varying the voltage that the battery controller is able to "baby" the battery through its charging cycle.
