Isn't this technology supposed to be in the 4680's?

A rough calculation based on how many miles they were planning on driving, expected size of the Cybertruck's battery and the expectation that most of the charging will be done at night.

Even half charge in the right area is going to require at least 20kw in solar panels, as well as at least 75kwh in batteries to pre-store the power while you are at work. Most likely you will need 25+kw and 110-120kwh of storage to power your house and a daily 250 miles on a Cybertruck. But...

Nope I did not think the whole thing through. Is it something that can be done without any significant technical issues? Definetly. Is it practical? If you are putting the panels on top to power your camper anyways it might be but most likely not. Over the course of the day you might...

Many solar systems run in the 400v range, which is the same as the charging system for the Teslas. The max practical solar for a very large 5th wheel might be as high as 5kw. At 400v we are looking at less than 15 amps. A heavy duty 12-10ga extension cord can handle that easily.

Exactly. If the crash gets to the rigid cells and foam you are already intruding into the passenger compartment in a very dangerous way.

If I remember correctly energy density was supposed to be part of the equation. However this is still good news on the overall system, and cost viewpoint.

Really? Even someone like me who customizes their own cars, has a degree in Electrical Engineering, and works with significantly higher voltages.

Holy crap.

How much power you can charge a battery (of the same chemestry etc) at is based on the battery capacity and at max rate including tapering down both battery sizes will charge in the same amount of time. For example a battery with 1 amphour of capacity being charged at 2 amps is being charged...

Its going to depend on if you are limited by the charger or by the battery. If the charger is able to supply enough power to max the larger pack then the smaller pack will go up with the same % charged rate as the larger pack while the larger pack will get more miles per hour charge rate. If...

Cameras are not a fix all but they do work often enough. The cameras on my house have worked twice for two different neighbors. (my cameras caught thieves at their houses). In my area many of the metal scrap yards are corrupt anyways. If they think your wire is stolen they offer much less...

Its discussed at 7:00-9:00, but looks like I am wrong about the cooling from the bottom. These cells must run massively cooler.

As far as the cooling it was expected, especially when Sandy Munroe confirmed cooling strips under the negative side of the cells. (Electrons flowing from the cells also carries heat with them) I expected the increase in charging capability as a result but previously didn't know how much it...

Yeah I have figured out how it would work after I posted. The minimum frequency would be determined by the capacitance created by the plates on the car and the plates on the ground.

A charged plate has an electrical field, for it to make a magnetic field you would need to be flowing electrons. You can have both an electric and magnetic field like you have around power lines. To move charge you need a conductive plate, sheet or wire in parallel. Capacitors are built...

You are thinking kilowatt hours. If your car takes 300wh to drive a mile at 60mph (1 minute per mile) it is drawing 18kw from the battery pack. From an earlier post there is a difference between an electric field and a magnetic field. When you rub a balloon on your head and your hair stands...

Using the model 3 and Y with their smaller pack have a peak charge just north of 3C which tapers to approximately 1C by 80%. If we apply that charge rate to my guesstimate of 200kwh that would be 600kw that the pack can handle. 324 would come out to 1.6C and if it has the same profile as the...

One of the things I did when I first put my order down was see what it would cost to drive. What I found is that a rough rule of thumb is you multiply what you pay per KWH by 10 and it comes out pretty closely to the fuel cost in an equivalent vehicle. It seemed to work fairly accurately...

One of the only arguments (because very specific conditions set) I have is he states that it costs $600 for a level 1 charger. Don't most EV's come with a 110/220 charge cord that you can plug into a standard 110 or 220 outlet?
