you still trust what they say in the chat? When I asked them about order dates last saturday, the guy told me my time would come and that many people had already ordered their leaf ...Jimmydreams wrote:I just had a chat with the Nissan people.

Me: it's the 28th of august already, and I still haven't received any instructions Me: I was wondering if you knew when I would actually be able to order Justin: You will receive an email letting you know its time for you to order. I do appreciate your patients. Justin: I do not have an exact date for you <Me>, only the month. You will be contacted for order instructions before months end. Many people have already placed their orders for their LEAF.

Meg: There will be test drives available later this year, but they will begin after the launch markets have been invited to make a finalized order. You have the option to wait until you have gotten a test drive to make a final order. However this may affect your delivery date. The order phase will not be refundable, it will require you to (at the end of the ordering process) go to your local Nissan LEAF certified dealer to sign the paperwork and go over the financing. Me: and if I make a firm order in august, I'll have to pay / finance the full amount of the car at that time ? Meg: No <Me>, but the agreements will be signed and possibly your down payment will be requested. As dealerships are responsible for that stage of the purchasing process, I would recommend contacting your preferred Nissan LEAF certified dealer and asking your questions.
Oh, I agree that it would be more comfortable. But as I said, I was talking about "battery demand reduction". For that matter, for the purposes of "battery demand reduction", you shouldn't heat or cool at all.evnow wrote: That is debatable. For one there is the comfort question - obviously better to preheat by the time you get into the car.
That is a very interesting speculation, and one that I suspect may be valid. AndyH or Gary? You guys seem to know about this stuff.wwhitney wrote:it might be the case that if the battery charger needs 3.3kw, and the HVAC needs 1.5kw, and the EVSE can supply 6.6kw, then in this situation the car can ask for 4.8 kw total. I don't know.
No, I don't take the CHAT people as Gospel, because they often know less than we do.gudy wrote:you still trust what they say in the chat? When I asked them about order dates last saturday, the guy told me my time would come and that many people had already ordered their leaf ...

A/C will be less (my guess is closer to 1000 watts), but I have not seen any numbers on the Leaf's System for cooling. For that matter I've not seen specific numbers for the heater either.Jimmydreams wrote:Do we know if heating/cooling takes more eneergy than is provided by an L1 charge? I can't imagine that it does.
I would think that during preheating/cooling the car while on L1 charging, you won't be ADDING any energy to your batteries, but I can't imagine that you'd be taking away from your SOC (State Of Charge). How much power does the heater/cooler really use???
ex. L1 charge provides 1000 watts to the battery for charging purposes (made up numbers!)
Heating might take 900 watts, leaving 100 watts (+100) going TO your SOC. (very little charging going on, since most of your energy from L1 is going to the heater.)
Cooling might use 750 watts, leaving 250 (+250) going TO your SOC. (a little more charging, but still not much)
Turn on heating, radio, NAV, fans on high, windshield wipers AND headlights, might use 1500 watts, leaving -500 watts coming FROM your SOC. (now, you're taking charge AWAY from your batteries and decreasing range)
Do we have any hard numbers yet on how many watts L1 provides for charge vs how many watts heating/cooling uses??
edit: this is why I wish there were seat heaters. I would not preheat the car but just turn on the seat heater which would use far less power than the cabin heater.
Do you really think the HVAC will run directly on shore power, and be 120v/240v capable? I don't. I suspect it will run on DC off the battery. In that case, the 3.3kW charger is still the choke point.LEAFguy wrote:That is a very interesting speculation, and one that I suspect may be valid. AndyH or Gary?
