No, not mute, but it may be moot. Or maybe not. I just know words, not engineering.

You got that right! It's soft and irrelevant.

There is a dedicated CAN bus that is present at the CHAdeMO port. You must establish a handshake via CAN frames in order to use the DC QC port. (There is a contactor that prevents charging until the communication is acknowledged.) The CAN frames indicate what voltage/current is needed to charge, and they regulate the charge process from start to finish according to what the battery ECU in the LEAF decides.

Technically the charger doesn't necessarily need to be isolated, as the LEAF's HV system is already isolated and includes ground leakage detection which will help ensure safety.

I suspect the hardest part is locating the Yazaki CHAdeMO connector.

Just ground the heck out of the charger case?

For those who hadn't noticed yet, an attempt to get the connector straight from Yazaki is being tracked here:

I think it is a great idea to have a Quick Charge in your garage! Even if it isn't capable of 0 to 80% in 30 minutes.

Has there been any activity on this project in (almost) four weeks ? 8-)

If a charger was available for under $4000 that could charge to 80% in 30 to 50 minutes, any small business like a restaurant or shopping center (WalMart) or grocery store might be willing to put one or two in. I think this might be a good way to build CHAdeMO infrastructure.

Just a thought.

It isn't 100% electric if you have to put gas in it.

As soon as someone passes along the CHAdeMO specification, we'll get active on this project, but so far all CHAdeMO participants have been tight-lipped! :D
