These are good thoughts but don't you think that a Frankenplug to CHAdeMO adapter would be more of a challenge since the charging protocols are different? For example for L2 charging, making a Tesla plug to J1772 adapter or cutting off the Tesla plug and putting on a J1772 is more doable since its the same protocol.TonyWilliams wrote:...Let's do one of the above as "Open Source"
In fact, wouldn't it be easier to put a CHAdeMO port on a frankenplug car like the BMW i3, than actually making an adapter from SAE CCS to CHAdeMO? I imagine one way to implement CHAdeMO is to intercept the car's charging handshake signals and tell it that it's OK to charge and then send in direct current into the battery using a CHAdeMO port.
I'm confident that any adaptor that includes differing communication protocols will be a challenge.
The adaptor that I suggested was to charge the 60,000 cars in the USA with a Frankenplug, not the other way around. Since the several CCS stations (all 23 of them) in the USA usually have a CHAdeMO station sitting right next to it, the odds of finding CHAdeMO in use and Frankenplug growing cobwebs is high. Let's put them to use !!!
Yes, adding a CHAdeMO port would likely be easier on i3, and we have that in the works for late 2015, just like we are currently doing on RAV4 EV and Mercedes B-Class ED.
