To be honest, it wasn't even my idea to begin with. I think it might have been Phil's (Ingineer) idea a while back when he was tossing around the idea of installing a third party 10KW charger in the front under the hood.
The beauty of this idea is that:
1) you don't have to rely on the flimsy wiring from the J1772 port to the back of the existing 3.3kw charger if the replacement charger is placed up front. You can just tap on the J1772 port directly with a new harness beefy enough to handle 10KW into the new 3rd party charger. This harness doesn't have to cost a lot of money because it should be short enough.
2) And if the output of this new 3rd party charger can tap on the CHAdeMO wiring already in place up front going to the battery, then no new long beefy harness is necessary to connect to the battery pack either.
3) You can just drop the 3rd party charger in the front under the hood, tap into the J1772 and CHAdeMO, and voila, you have even a better upgrade solution at 10kw than Nissan's 6.6kw solution.
