Can you actually upgrade to 6 kW (not 6.6, BTW) after buying S ? I thought the charger upgrade was a factory installed option.
I wish we would let the 6.0kW / 6.6kW issue die a peaceful death. Nissan markets the charger as a 6.6kW. That's the max it will pull from the wall socket. No, it doesn't match up with "3.3kW" nomenclature, since that can pull up to 3.8kW from wall socket.
If we're going to really split hairs, it's an "up to" 6.6kW charging system, since it can and does pull significantly less in many different conditions that I've outlined a few posts up. There's plenty more to split. If the battery is cold or seriously degraded, that 6.0/6.6kW charger won't put 6.0kW into the battery.
Tesla uses the same "from the wall socket" rating on their equipment, too: 40 amps at 250 volts is 10kW. But, just like the LEAF, it will be far less than that at lower voltages and with less than 40 amp pilot signals. By the same token, increasing the voltage to 277 volts used by virtually every street light in the USA/Canada lowers the amps the 36 so as not to exceed 10kW.
Lets just simply explain the nomenclature differences to newbies, and leave it at that.
