I agree, the car should be carefully designed to protect itself from bad, false, wrong, failed, or faulty inputs from the external "charge" devices.

Measuring the inputs before closing internal relays, and continuing to monitor for potentially harmful input(s) would seem to be a necessary part of the "basic safety" of a design (to me). But, some designers tend to assume the inputs will be "up to spec.", and "nothing can go wrong, go wrong, go wrong, ...".

One should not have to "bet the car" and depend upon the random charger working properly (up to the standards) each and every time one connects to "e-fuel" (which could be frequently).

Perhaps Nissan will let us know if they have included such "protection"?

For example, one is L3 charging at 150 amps, and the car signals the "charger" to reduce to 50 amps, but the charger does not respond (or increases the voltage to increase the current). The car needs to protect itself with a big relay (or some such) that can be "opened" (interrupt the high voltage and high current) to "save" the battery pack from damage.

That's what fuses are for. :)

Sorry, a 200-amp fuse (or some such) will not sufficiently protect your vehicle.

See my example.

It's already been stated elsewhere that the Level 3 DC charge port will have a CAN bus for communication between the charger and the vehicles ECU's, the external charger is supposed to follow orders regarding charge current/voltage from the onboard BMS/ECU's, these are smart chargers, they likely have safe guards built in. It will all be defined in the ISO DC standard, if they can ever get it done :)

ACK! Which leaves us back at square one....not really knowing for sure.

Yeah, and then that raises yet another question... can the level 3 charging port be installed later as an accessory/upgrade? That would work for me, take the car without, then add it later if charging stations appear and I feel like I want it. Also give them a chance to settle further on standards.

you are overlooking one thing: The DC charging port could also be used for your OWN higher current external charger. I fully expect 3rd partys to come up with 8-12KW external DC chargers that use the dedicated DC port, for those who have places to go and people to meet :-O who has 8 hours to wait for a charge even at home sometimes... with no external DC charging port, you will only have the 3.3KW onboard S L O W charger.

I don't remember a pop-up either ... but now that you mention "pop-up" ... I have a "pop-up" blocker ... so that might explain it for me (and maybe others) !

I thought I had been back to this thread, but perhaps not. We've pretty much confirmed it..AS OF RIGHT NOW SL only, but an extra cost option. Subject to change, of course, once Nissan figures this stuff out once and for all.
