Yes, these proprietary hardware/protocl issues are annoying. Especially since it did not take a bunch of rocket scientists to come up with
a glorified power plug.
Conceptually it seems straightforward, so again, in a few years you can just buy this stuff off the shelf.
My main concern is proper throttling of load being controlled by the BMS. If we can control the load, get the connectors and so on, Bob's your uncle, we're don! I agree ideally we just get a 100 or so TEPCO plugs and J1772 receptacles, a enough and variously sized rectifiers and transformers, encase and wire it water-tight and market them to a handful of hobbyists and disenfranchised LEAF owners. Can't imagine more than a 1,000 or so of these being sold though as the 201x LEAF (maybe 2, maybe 3, who knows) will have the 6.6kW but there would still be niche folks like myself with a desire for 19kW power. So in that case, we wait for the TEPCO plug to get mass-produced in China (or for an SAE J1772+2 Prong DC to replace it and for SAE Level 3 to TEPCO plugs to become ubiquitous and obviously then we could match the SAE Level 3 which may be licensed more cheaply). Then we test the 6.6kW rectifier, make it work, then look into 10kW and 20kW upgrades at cost + additional research and labor.
But I just can't see all this practically happening when the TEPCO plug itself is costing $2700. I'd expect the 20kW rectifier to be maybe that much but the plug? It just can't be economical if the plug is the most expensive component.
And that's my 2¢ and armchair engineering.
: Thanks to EVDriver the TEPCO plug cost has been corrected.
