I would wait because there's no promise when the bidirectional charging will be implemented. We don’t know what additional part numbers will be needed...
That is good logic. I am following the same except...the more I look into the new tax credit law, the more confused I get. Right now, I am not sure I will qualify again because it looks like that $1,000 tax credit is now restricted to non urban areas. The Feds have put out a map that shows where those non urban areas are and even though we are way up by the Canadian border, in a little community of about 5,000, we are not a non urban area. Thus, I am not sure, but I think I may no longer quality under this new tax credit portion of the law. Thus, while I am enjoying the faster charging capabilities of the Lucid Charger, the tax credit savings for installation of the charger may elude me. Please, someone, tell me I am wrong and help get that tax credit for me... Click Here an article on this subject:
Whoo Hoo!
I understand your goal to charge only during that window and save some money, but spending all of the extra $$$ on 100 amp charger and possibly a switching device seems to negate that benefit. Unless you are routinely running the car all the way down to zero before charging every day, a slower, lower amperage, charger should be sufficient. I have a 40 amp charger on a 50 amp circuit and it’s usually more than enough to charge the car in five hours. Those occasional times when it is really low, and in your case charges at the higher rate electricity, would be few and far between. No?
i have 150amp service to my townhouse with two HVAC systems with AC on electric and one dryer. Everything else is gas (heat, range , hot water. ). I have successfully charged with the Lucid charger at the full 80 watts with both AC units and dryer running. I’ve had my charger since mid December and so far no issues. YMMV
The electrician should perform a load calculation for submittal with the permit. My electrician did that and provided me with options on what size circuit is compatible with my panel and the installation options. I elected to go with a 70 A circuit breaker, Lucid Home charger operating at 56 A. This was the largest wire that would fit in a 3/4" conduit. No panel change. Rewired two existing circuit breakers to have enough room to install the 70 A breaker.
Here are some numbers to put what you have/want in context. The Grand Touring has a 100kWh battery pack; the Touring a little less. If you charge at 20% to 80% for the GT, that would take a little over 6 hours using a 40A charger (hardwired or plugged into a NEMA 14-50 receptacle). If you hardwire a 48A charger, you cut the time by 20%; if you use the Lucid charger, you cut that time in half. Unless you only sleep 3 hours/night, you don't gain much with a Lucid charger IMO. Of course, in an emergency, the Lucid charger may bail you out. With the Lucid charger, you will more than double your installation costs - more for the charger and way more for the wiring. That big #3 or #2 doesn't bend easily.
Thanks for this. I also didn't put the higher installation costs into consideration, I will ask for a quote for that as well and compare.
fwiw .. I installed a hardwired Chargepoint on a 60A breaker (=48A draw); which I've found to be plenty for home/overnight charging. Unless you are always taking long road trips, you shouldn't be charging past 80% or so (for daily driving) .. I only charge it when it's down in the 50% range (or lower) .. from 50-80%, my Chargepoint usually takes ~3 hrs ... good luck!
Thanks for all the input. I will most likely be going with the Lucid 100amp charger. I know I will have a few days when I will need an emergency charge, also future proofing too if/when I get the gravity.
Do you really need 100 Amp to charge your car overnight? I would get another quote.
Yes I think its crazy too, my panel is just above my garage so I don't believe its the length. I also have my generator wired from my garage right beside the panel, which is probably about 20-30ft of wire run. I will probably look for a third party
It's always a good idea to get a few quotes. Beyond any price differences, it's useful to hear the thoughts and ideas of three individuals on the best installation.
